Summary of the invention

The problem that invention will solve

The heat-proof quality that Vacuumed insulation panel compares existing hard polyurethane foams has the heat-proof quality of such as more than 6 times.Therefore, from the angle etc. of energy-saving, be formed in the space between outer container and interior case, except configuration hard polyurethane foams, also configuring Vacuumed insulation panel.Further, along with the raising of the requirement of energy-saving in recent years, as the heat insulating box such as described in patent document 1, the use amount being configured at the Vacuumed insulation panel of heat insulating box also increases.

On the other hand, in recent years for heat insulating box, from the angle of the high capacity of space saving, internal volume, also require the wall thickness reducing the space, the i.e. heat insulating box that are formed between outer container and interior case.But existing heat insulating box is made based on following technological thought: hard polyurethane foams mainly bears heat insulating function, and Vacuumed insulation panel assists the heat insulating function of hard polyurethane foams.At this, existing heat insulating box obtains casing intensity by hard polyurethane foams is filled into the space between interior case and outer container with predetermined density, but when the thickness that will reduce polyurethane is to reduce the thickness of wall, the less thick of polyurethane, the density of polyurethane increases, heat-proof quality decline, be therefore difficult to meet heat-proof quality and obtain needed for casing intensity.

Namely, have in the equipment of Vacuumed insulation panel at existing heat insulating box or refrigerator etc., the intensity of the heat-proof quality of wall and casing and casing, wall is guaranteed by hard polyurethane foams, reduce the thickness of hard polyurethane foams to reduce the wall thickness of heat insulating box, then can produce that the heat-proof quality of heat insulating box is not enough or intensity is not enough and be difficult to realize the problem of the minimizing of wall thickness.

At this, in the heat insulating box described in patent document 1, the use amount (covering rate) of Vacuumed insulation panel increases, the Deflection Modulus of Elasticity (rigidity of hard polyurethane foams) of hard polyurethane foams increases, and therefore also thinks and can reduce wall thickness to a certain extent from the intensity face of heat insulating box.But, heat insulating box described in patent document 1 mainly bears heat insulating function by hard polyurethane foams and Vacuumed insulation panel assists the technological thought of the heat insulating function of hard polyurethane foams to be made, hard polyurethane foams mainly bears heat insulating function, Vacuumed insulation panel assists the heat insulating function of hard polyurethane foams, guarantees the heat-proof quality of heat insulating box and the intensity of wall by hard polyurethane foams.But during the less thick of hard polyurethane foams, density, Deflection Modulus of Elasticity can increase, but thermal insulation worsens.Therefore, in order to suppress the decline of the heat-proof quality of hard polyurethane foams, be set to that the Deflection Modulus of Elasticity, the density that make hard polyurethane foams are below predetermined value (below Deflection Modulus of Elasticity 10MPa, density 60kg/m ³below).When Deflection Modulus of Elasticity, density exceed predetermined value, although casing intensity is met, heat-proof quality worsens, thus is difficult to use.Therefore, heat insulating box described in patent document 1 is in order to ensure both the intensity of casing, wall and heat-proof quality, need to guarantee that the thickness of polyurethane is more than to a certain degree, need the polyurethane stream thickness at the position being adjusted to filled polyurethane to be more than predetermined thickness to make the density after polyurethane foam for (density 60kg/m below predetermined value for this reason ³below), thus exist and be difficult to reduce the problem of wall thickness.

In addition, patent document 2 is as the intensity measure of heat insulating box possessing Vacuumed insulation panel, employ following Vacuumed insulation panel, interior case, outer container: the outsourcing material for Vacuumed insulation panel is shaping etc. and be shaped to target shape by vacuum forming, compressed air by plastic material etc., fill granular core in inside, thus be shaped to the concaveconvex shape that ensure that intensity.But, make interior case, outer container be with the convex-concave profile of the concavo-convex basic similar shape of the outsourcing material of Vacuumed insulation panel and embed and make interior case and outer container have intensity, thus the shape of outsourcing material, interior case, outer container becomes complicated, there is the problems such as cost rising, assembleability deterioration.In addition, from the angle guaranteeing intensity, Vacuumed insulation panel also needs outsourcing material to be shaped to concaveconvex shape, the core enclosed in outsourcing material also needs to be the shape of the concaveconvex shape according to outsourcing material, therefore core needs to use the shot-like particle with mobility, cost raises compared with the fiber-like cores such as glass fibre, and heat-proof quality also exists the possibility of variation.In addition, the back side of indoor (accommodation spaces of the reserve in heat insulating box etc.) is concaveconvex shape, complex-shaped, and aesthetic appearance is deteriorated.

Therefore, in existing heat insulating box or equipment, especially refrigerator, be difficult to guarantee predetermined heat-proof quality and predetermined casing intensity and make to comprise thermal wall or the thermal insulation barriers slimming of Vacuumed insulation panel, therefore, the further expansion of internal volume or the miniaturization of appearance and size that realize heat insulating box, refrigerator, equipment etc. is difficult to.

In addition, in the refrigerator described in patent document 3, patent document 4, the track component of the box body of the storeroom of support drawer formula or door frame be fixed to thermal wall (interior case or the polyurethane thermal insulation barriers between interior case and outer container or the strengthening part be located between interior case and outer container) by screw.But, when being configured with Vacuumed insulation panel between outer container and interior case, when the thinner thickness of the thermal insulation barriers between Vacuumed insulation panel and interior case, likely because the uneven etc. of thickness of Vacuumed insulation panel causes the hold-down screw of track component or door frame to damage or destroy the outsourcing material of Vacuumed insulation panel and cause the decline of the heat-proof quality of Vacuumed insulation panel, the decline of reliability.

In addition, in order to not damage Vacuumed insulation panel, the length of the threaded portion of shortening screw can be considered, if but the intensity (such as density, bending resistance elasticity etc.) being filled in the polyurethane thermal insulation barriers between Vacuumed insulation panel and interior case is less, then the maintenance intensity of screw is also more weak and intensity that the is thermal wall be integrally formed with polyurethane is also more weak, therefore likely cause thermal wall or box deformation or screw loosens, reliability reduces, and therefore flighted length can not be shortened to below predetermined length.Therefore, be fitted through screw or embedded structure etc. in the thermal wall with Vacuumed insulation panel to keep or another fixing parts (such as support the ballast support parts that the track component of box body or door frame etc. support weight, or generate the cooler of the cold air being used for cold storage room or the vibration effect parts etc. of the impact of vibration when being subject to operating to the fan etc. of storeroom blowing cooling air) time, the position of installing needs the wall thickness that can obtain installation strength, in addition, according to the relation of the installation strength of screw, the length of the threaded portion of the fixed parts such as screw be also difficult to for predetermined length (such as 15mm) below, therefore be difficult to reduce wall thickness, be difficult to increase internal volume.

The present invention completes to solve the problem, and its main purpose is heat-proof quality and the intensity of the heat insulating box improving refrigerator compared to existing technology.In addition, its object also has to obtain and can realize the heat insulating box of the slimming of thermal wall or thermal insulation barriers, refrigerator, water storage device, has the equipment etc. of high-temperature portion or low-temp. portion.

In addition, its object is to the heat insulating box, refrigerator, water storage device, equipment etc. that obtain the internal volume (extension of the volume of room) that can expand heat insulating box, refrigerator, equipment etc. compared to existing technology or the appearance and size (miniaturization of appearance and size) reducing heat insulating box, refrigerator, equipment etc.

In addition, its object is to obtain the heat insulating box, refrigerator, water storage device, equipment etc. that also can realize the slimming of thermal wall or thermal insulation barriers when being fitted through the maintenance such as screw or embedded structure or fixing another parts (such as ballast support parts or vibration effect parts etc.) in the thermal wall with Vacuumed insulation panel.In addition, its object is to obtain the heat insulating box, refrigerator, water storage device, equipment etc. that reliability is high, internal volume is large.

In addition, its object is to reduce wall thickness and improve the aesthetic appearance of indoor (such as receiving in the storeroom of reserve).

(body structure of refrigerator)

Fig. 4 is the sectional elevation of the refrigerator of embodiments of the present invention 1.Figure is sectional elevation when cutting refrigerator with the face vertical with the above-below direction of refrigerator 1.In the diagram, equal with Fig. 1 ~ Fig. 3 part is marked with same-sign and omits the description.

In the diagram, the heat insulating box 700 forming refrigerator 1 is made up of outer container 710 and interior case 750, is configured with Vacuumed insulation panel 400 between outer container 710 and interior case 750.Vacuumed insulation panel 400 is located at the back side of refrigerator 1, directly pastes outer container 710 via PUR, double faced adhesive tape etc. as the 2nd bonding agent of the 2nd sandwiched parts.In addition, Vacuumed insulation panel 400 directly pastes a part (such as forming the left and right directions substantially central portion of the wall at interior case 750 back side) for interior case 750 by bonding agent, left and right end portions (corner part) near sidewall 790 except the substantially central portion at interior case 750 back side is formed with the protuberance 450 given prominence in front face side than back face wall 730, Vacuumed insulation panel 400 is configured to predetermined length overlapping with this protuberance 450, but also can exist at protuberance 450 and do not configure Vacuumed insulation panel 400 and the position of only filled polyurethane.In addition, between interior case 750 and Vacuumed insulation panel 400, be filled with the bonding agent (such as hard polyaminoester etc. can be used to have the foaming heat insulation part of self-adhesiveness) as the 1st sandwiched parts, Vacuumed insulation panel 400 is located between interior case 750 and outer container 710 via the bonding agent (such as hard polyaminoester etc.) as the 1st sandwiched parts.Therefore, Vacuumed insulation panel 400 is by the 1st sandwiched parts and the 2nd sandwiched adhering components or cementation or be fixed to interior case 750 or outer container 710.

At this, the back side shape of interior case 750, when seeing from the front face side (storeroom side) of refrigerator 1, forms the recess 440(of the groove-like of upper and lower substantially central portion depression also referred to as the 1st recess).In the recess 440 that this substantially central portion is formed, Vacuumed insulation panel 400 directly pastes outer container 710 and interior case 750 via bonding agent.In addition, when seeing from the front face side (storeroom side) of refrigerator 1, the back side shape of interior case 750 becomes width (left and right directions) end side and compares width (left and right directions) the substantially central portion convex form that forwardly side, opening portion (storeroom side) is outstanding.In other words, the substantially central portion that the back side shape of interior case 750 has left and right directions compares the groove-like and recess 440 that cave in left and right end portions side direction outer container side (rear side of refrigerator), and this recess 440 is located at the above-below direction of refrigerator in storeroom (such as refrigerating chamber 2).

That is, form recess 440 by the side 452 of protuberance 450 and back face wall 730, formed back face wall 730 inner face (storeroom side) interior case 750 and formed back face wall 730 outside outer container 710 between be provided with the Vacuumed insulation panel 400 of tabular.At this, although not shown, also the Vacuumed insulation panel 400 that tabular is set between the interior case 750 of inner face (storeroom side) of sidewall 790 and the outer container 710 of the outside of formation sidewall 790 can formed.Be located at the cold air wind path 760 of back face wall 730 or recess 440, by there is the 1st wind path accessory 762 as cap assembly of aesthetic appearance and being located at the rear side (interior case 750 side) of the 1st wind path accessory 762 and the 2nd wind path accessory 764 with thermal insulation is formed, be configured in recess 440.This 1st wind path accessory 762 as cap assembly or the 2nd wind path accessory 764 have installation portion (holding section), be embedded into the installation portion (holding section) of being located at protuberance 450 or back face wall 730 or by fixed parts such as screws, installation portion engaged with each other, thus cap assembly 760 is installed to protuberance 450 or back face wall 730.

At protuberance 450 place of left and right end portions side being formed at the back side in this storeroom, the center side (scope of overlap length X) of width, Vacuumed insulation panel 400 is configured between outer container 710 and interior case 750, the bonding agent (foaming heat insulation part 701, such as hard polyaminoester for self-adhesiveness) as the 1st sandwiched parts is filled with between Vacuumed insulation panel 400 and interior case 750, in addition, bonding by the 2nd bonding agent as the 2nd sandwiched parts between outer container 710 and Vacuumed insulation panel 400.End side stuffed heat insulated 701(such as hard polyaminoester between outer container 710 and interior case 750 of the width of protuberance 450), there is the part that Vacuumed insulation panel 400 is not set.Certainly, at protuberance 450 place, Vacuumed insulation panel 400 is increased to increase the configuration area of the Vacuumed insulation panel 400 of width at width, heat-proof quality and casing intensity can be improved, but cost raises, if therefore heat-proof quality and intensity are more than predetermined value, then can set the part that Vacuumed insulation panel 400 is not set.

At this, in recess 440, Vacuumed insulation panel 400 and outer container 710 are directly pasted via the 2nd bonding agent as the 2nd sandwiched parts, and the bonding agent that Vacuumed insulation panel 400 and interior case 750 have self-adhesiveness and foaminess via the polyurethane etc. as the 1st sandwiched parts is pasted.(between Vacuumed insulation panel 400 and interior case 750, be such as filled with the hard polyurethane foams as bonding agent.）

Therefore, in the heat insulating box possessing Vacuumed insulation panel or refrigerator, with the width at the storeroom back side as prior art (such as patent document 2) thermal insulation barriers 701 that polyurethane etc. is main purpose with heat insulation be not set at the configuration section of Vacuumed insulation panel and directly arrange at interior case 750 compared with the situation of Vacuumed insulation panel 400, the protuberance 450 be made up of the thermal insulation barriers such as polyurethane 701 is formed along the vertical direction in the present embodiment in left and right end portions side (width end side), therefore by forming this protuberance 450, the torsional strength of casing can be improved, buckling strength.In the formation shown in patent document 2, there is not the lap of the configuration section of protuberance 450 and Vacuumed insulation panel 400 in the width at the storeroom back side, therefore, when casing reverses, protuberance 450 and Vacuumed insulation panel 400 are cut off, and may produce the worry of intensity decline, casing breakage.At this, the side portion (only the part of outsourcing material) of Vacuumed insulation panel does not have core, and therefore do not have heat insulating function, intensity is also weak in addition, therefore for the side portion of Vacuumed insulation panel, gets rid of from the formation accessory of Vacuumed insulation panel.

At this, as shown in the embodiment, at the width at the storeroom back side, when protuberance 450 is configured to that at least local is overlapping with the configuration section of Vacuumed insulation panel 400 when overlap (be arranged to overlap length X), the hard polyurethane foams being filled into the inside of protuberance 450 is also filled into the part between the Vacuumed insulation panel 400 of the end side of the width (left and right directions) of Vacuumed insulation panel 400 and interior case 750, therefore, it is possible to make to be filled into and the thickness of hard polyurethane foams between the Vacuumed insulation panel 400 of protuberance 450 position in opposite directions and interior case 750, larger than the thickness be filled into the Vacuumed insulation panel 400 of recess 440 position in opposite directions and the hard polyurethane foams of interior case 750, so, the bond area of hard polyurethane foams relative to Vacuumed insulation panel 400 can be increased, and the thickness of the hard polyurethane foams of Vacuumed insulation panel 400 part can be increased, the bond strength of the hard polyurethane foams therefore in protuberance 450 and Vacuumed insulation panel 400 increases.

Therefore, even if the thickness of the hard polyurethane foams between the Vacuumed insulation panel 400 at thinning recess 440 place and interior case 750, also significantly can improve protuberance 450 and Vacuumed insulation panel 400 and protuberance 450 and sidewall 790(or the surrounding wall that protuberance 450 is set) bond strength, significantly improve the intensity of casing.In addition, at protuberance 450, can increase the thickness of hard polyurethane foams, even if therefore there is the part not arranging Vacuumed insulation panel 400, heat-proof quality also improves.

In addition, in embodiments of the present invention, do not need in order to ensure casing intensity, Vacuumed insulation panel, interior case, outer container to be shaped to complicated shape as existing patent document 2, in addition, the core of Vacuumed insulation panel can use at a low price and the core (cotton like core, non-woven fabrics core etc.) of the good organic fiber of heat-proof quality, inorfil, therefore, it is possible to obtain low cost, structure simple and the heat insulating box that heat-proof quality is high, refrigerator, showcase, hot water supply device, possess the equipment etc. of Vacuumed insulation panel.

Therefore, there will not be following situation: such as, box back surface is out of shape and is formed concavo-convex in storeroom; In addition, the door of storage room (such as refrigerating-chamber door 7) that such as box deformation and making is located at before storeroom (such as refrigerating chamber 2) tilts; In addition, when such as clamshell doors, one side of the door (7A, 7B) of left and right tilts and causes dislocation.Therefore, it is possible to successfully carry out the opening and closing of door of storage room, in addition, the dislocation of the door of storage room of left and right can not be caused, therefore (aesthetic appearance is good) attractive in appearance.In addition, different or tilt about the setting height(from bottom) of the shutter door that the sidewall in storeroom (such as ice-making compartment 3, switch room 4, vegetable compartment 5, refrigerating chamber 6 etc.) inwall or left and right can not be caused because of box deformation to arrange, the track component of drawer type box body, therefore, it is possible to successfully carry out the discrepancy of box body, obtain reliability refrigerator high, easy to use, equipment.

In addition, when Vacuumed insulation panel 400 is tabular, under the state at back side Vacuumed insulation panel 400 being equipped on refrigerator 1, easily bend at left and right directions (width) or fore-and-aft direction and easily reverse, about this point, under the state being equipped on the equipment such as refrigerator, if left and right end portions side is overleaf provided with the protuberance 450 of the thermal insulation barriers such as polyurethane in above-below direction formation and Vacuumed insulation panel 400 and the polyurethane be filled in protuberance 450 is integrally formed, then interior case 750, Vacuumed insulation panel 400, outer container 710 is bonding by protuberance 450 one, therefore, it is possible to improve the buckling strength (buckling strength especially in front-rear direction) of casing 700, torsional strength.Therefore, can suppress the opening portion deflection deformation of the storeroom of front openings or because of the seal member of opening portion dislocation etc. and cause the problem of cooling gas leakage, thus obtain that reliability is high, high-performance and energy-conservation heat insulating box, refrigerator, possess the equipment of Vacuumed insulation panel.

In addition, between interior case 750 and Vacuumed insulation panel 400, there is the position (protuberance 450) that setting is the foaming heat insulation parts such as the polyurethane of main purpose with heat insulation, and to arrange be not the bonding agent of main purpose with heat insulation (be such as main purpose owing to being not main purpose with heat insulation with bonding, as long as therefore there is self-adhesiveness, can be polyurethane etc.) position (recess 440), therefore, the position (recess 440) arranging the bonding agent with bonding being main purpose is compared with arranging with heat insulation the position of the thermal insulation barriers such as polyurethane being main purpose, without the need to the predetermined thickness as the thermal insulation barriers for obtaining heat-proof quality, as long as have predetermined adhesive strength.Therefore be that the position (such as recess 440) that main purpose uses can make the thickness of bonding agent quite little with bonding.Therefore, time as bonding agent use hard polyaminoester, comparing with heat insulation is that the position that main purpose uses can make the thickness of polyurethane quite little.Therefore, it is possible to make the amount of the thickness difference of wall thickness reduction bonding agent, thus the internal volume of storeroom can be increased, obtain refrigerator easy to use, equipment.

At this, storage controls lead-in wire storage member and the pipe 720 of the lead-in wires such as the driving power line of distribution, compressor or fan etc., is embedded in the thermal insulation barriers 701 such as the polyurethane forming protuberance 450 at above-below direction.The control distribution of the running control of open and close controlling, compressor 12 or the circulating cold air fan 14 etc. for carrying out various air door etc. is received, for lead-in wires such as the power lines to the supply such as compressor 12 or circulating cold air fan 14 electric power in this pipe 720.Control the lead-in wire such as distribution, power line pass through pipe 720 in and be connected with such as lower component: being located at the compressor 12 configured in the Machine Room 1A of the bottom (or top) of refrigerator 1; Be located at the back side of refrigerator 1, bottom surface or control device above (controlling substrate etc.) 30; Be located at the circulating cold air fan 14 of cooler room 131 grade; Be located at the switch room air door 15 of cold air wind path, refrigerating chamber air door 55; At the guidance panel 60 etc. that the shutter door (such as refrigerating-chamber door 7) arranged in the mode covered before storeroom (such as refrigerating chamber 2) is arranged.

The width being located at the left and right directions of the Vacuumed insulation panel 400 at the back side of refrigerator 1 is less than the width between the storeroom inner surface 791,792 of the sidewall 790 of refrigerator 1, multiple filling mouths 703,704 of the thermal insulation barriers such as the polyurethane that the end that can not be blocked in the left and right directions at the back side of refrigerator 1 is arranged, can not block the filling stream from thermal insulation barriers such as the polyurethane of filling mouth 703,704 filling.

At this, be located at the width of the left and right directions of the Vacuumed insulation panel 400 at refrigerator 1 back side width (distance) of (storeroom is left inside face the wall and meditate 791 and storeroom is right inside faces the wall and meditates between 792) when between the storeroom inner surface of the sidewall 790 with refrigerator 1 identical or less than it time, the filling mouth of the thermal insulation barriers such as polyurethane can not be blocked or fill stream, thus polyurethane thermal insulation barriers is filled without interruption, the lower degradation of heat-proof quality can not be there is, therefore preferably.As long as but Vacuumed insulation panel 400 is configured in the filling mouth 703 with thermal insulation barriers such as the polyurethane of the left and right end portions of the rear side being located at refrigerator 1, the allocation position of 704 is identical or compare filling mouth 703, 704 positions being close to central side (direction, inner side), the filling mouth 703 of polyurethane thermal insulation barriers, 704 would not be blocked by Vacuumed insulation panel 400, therefore can not hinder from filling mouth 703, the thermal insulation barriers such as 704 polyurethane of filling are in sidewall 790, or in protuberance 450, or between Vacuumed insulation panel 400 and interior case 750 etc. flow (being filled), filling polyurethane can not be there is bad etc., heat-proof quality also can not decline.

At this, if Vacuumed insulation panel 400 inner surface of comparing the sidewall 790 of refrigerator 1 to the protruding outside and filling mouth 703,704 blocking polyurethane thermal insulation barriers of width at least partially, the polyurethane of then filling from the filling mouth 703,704 of the thermal insulation barriers such as polyurethane may to be intercepted or hinder in sidewall 790 or in protuberance 450 by Vacuumed insulation panel 400 or flowing between Vacuumed insulation panel 400 and interior case 750 etc., at sidewall etc., the filling of the thermal insulation barriers such as polyurethane may occur bad and heat-proof quality is declined.

Therefore, Vacuumed insulation panel 400 is with can not from the filling mouth 703 of the thermal insulation barriers such as polyurethane of left and right end portions of rear side being located at refrigerator 1, 704 degree being exposed to outside are configured in the scope of the filling mouth 703 in left side (side) of left and right configuration and the inner side of the filling mouth 704 of right side (the opposing party), thus can not intercept or hinder from filling mouth 703, 704 thermal insulation barriers such as polyurethane of filling are in heat insulating box (between interior case 750 and outer container 710, such as, in sidewall 790, in protuberance 450, between Vacuumed insulation panel 400 and interior case 750, between Vacuumed insulation panel 400 and outer container 710 etc.) filling.Therefore, high performance heat insulating box, refrigerator that heat-proof quality can not reduce is obtained.

At this, when the width of Vacuumed insulation panel 400 is exposed to outside (allocation position that the width end position of Vacuumed insulation panel 400 is configured to the filling mouth 703,704 of the polyurethane etc. than the left and right end portions being located at refrigerator 1 rear side is close to outer fix) from the filling mouth 703,704 of the thermal insulation barriers such as polyurethane of the left and right end portions being located at refrigerator 1 rear side, filling mouth 703,704 may be blocked by Vacuumed insulation panel 400.Therefore, block to prevent Vacuumed insulation panel 400 and fill mouth 703,704 at least partially, be advisable arranging the notch part such as breach or opening 33 with filling mouth 703,704 part in opposite directions in Vacuumed insulation panel 400.So, the width of Vacuumed insulation panel 400 can be increased, thus can heat-proof quality be improved.

In the present embodiment, forming in protuberance the thermal insulation barriers 701 such as (or between interior case 750 and Vacuumed insulation panel 400) filled polyurethane between case 750 and outer container 710 or configure the thermal insulation barriers of other accessories (thermal insulation barriers beyond polyurethane), to improve the intensity of heat insulating box 700.But when wanting the intensity improving heat insulating box 700 further, can in protuberance 450 near (near the width end of such as between Vacuumed insulation panel 400 and interior case 750, Vacuumed insulation panel 400 etc.) or protuberance 450 outside (such as the inner side of case 750, the outside of interior case 750) of such as protuberance 450 strengthening part is set.

This strengthening part is less on the impact of the decline of heat-proof quality when parts (such as the resinous resin component etc.) for such as heat conduction rate variance, therefore preferably.If but the surrounding of strengthening part is covered by thermal insulation barriers, even if then for the parts of metal (aluminum or aluminum alloy etc.) also can suppress the reduction of heat-proof quality, therefore preferably.The shape of this strengthening part can be bar-shaped (pole or square rod etc.) or tubulose.In addition, can be configured to arrange rib etc. at interior case 750, as long as the casing intensity such as torsional strength, buckling strength of heat insulating box 700 can be improved.At this, strengthening part is made in pipe 720 or refrigerant piping 725 substitute that also storage can be controlled the lead-in wire such as distribution, power line, if pipe 720 or refrigerant piping 725 substitute are made strengthening part, then need the accessory for strengthening no longer in addition, therefore cost reduces, and the reinforcement of heat insulating box can be carried out, therefore, it is possible to improve the casing intensity of heat insulating box.In addition, strengthening part can be configured in the space in protuberance 450, between interior case 750 and outer container 710, strengthening part can not directly be seen by user, and therefore aesthetic appearance is also improved.Therefore, low cost, reliability is high, aesthetic appearance is good heat insulating box, refrigerator, equipment is obtained.

(recess is used as cold air wind path one of ())

The part that interior case 750 and Vacuumed insulation panel 400 are directly pasted via bonding agent (can be the foaming heat insulation part of self-adhesiveness) and recess 440, cave in relative to the protuberance 450 arranged at the corner part with the surrounding wall be formed at around recess 440 (such as sidewall 790 or roof 740 or partition wall 24), therefore this depressed part can be used as cold air wind path 760.(at this, such as, when storeroom is refrigerating chamber 2, cold air wind path 760 is equivalent to refrigerating chamber cold air wind path 50, and when storeroom is switch room 4, cold air wind path 760 is equivalent to switch room cold air wind path 16, and when storeroom is vegetable compartment 5, cold air wind path 760 is equivalent to vegetable chamber cold air wind path.）

When recess 440 is used as cold air wind path 760, the opening portion with the 2nd wind path accessory 764 of the opening portion of U-shaped (or concave shape) is configured to storeroom side opening, the opening portion of the U-shaped of covering the 2nd wind path accessory 764 will be configured to as the 1st wind path accessory 762 of wind path cover, and the opening portion of the 2nd wind path accessory 764 is blocked by the 1st wind path accessory 762, thus the cold air wind path 760 of roughly confined space can be formed.1st wind path accessory 762, the 2nd wind path accessory 764 are formed by the such as heat insulating member such as foam styrene or resin.The 2nd wind path accessory 764 being configured at recess 440 is made up of the wind path back part 765 of rear side, the wind path side members 766 of side.

The interior case 750 forming recess 440 is configured with in the rear side of the parts (wind path back part 765) of the rear side of the 2nd wind path accessory 764.Vacuumed insulation panel 400 is arranged across bonding agent with the interior case 750 forming back face wall 730, in addition, be provided with the protuberance 450 of interior case 750 formation at the side of the parts (wind path side members 766) of the side of the 2nd wind path accessory 764, in protuberance 450, be provided with the thermal insulation barriers such as polyurethane 701.Therefore, even if the wind path back part 765 of formation the 2nd wind path accessory 764, wind path side members 766 do not have thermal insulation and can guarantee heat-proof quality yet.Namely, the rear side of cold air wind path 760 by the Vacuumed insulation panel 400 be configured in back face wall 730 to guarantee heat-proof quality, the side of cold air wind path 760 guarantees heat-proof quality by the thermal insulation barriers 701 in protuberance 450, therefore, form the wind path back part 765 of the 2nd wind path accessory 764, wind path side members 766 can be the thermal insulation barriers such as foam styrene, but even not there are the parts of the resin-made or metal etc. of heat-proof quality, also can guarantee the heat-proof quality of cold air wind path 760.Thus, the parts forming the 2nd wind path accessory 764 can be the thermal insulation barriers such as the foam styrene with thermal insulation, but even not there are the parts of the resin-made of thermal insulation or metal etc., also can suppress the dew attachment that dew etc. is attached to the accessory forming cold air wind path 760 etc. or causes because producing dew.

In addition, the 1st wind path accessory 762 such as has the heat insulating member of thermal insulation or resin etc. by foam styrene etc. and forms, and in storeroom lateral inhibition, dew attachment is to prevent the attachments such as dew or to produce.In the drawings, 1st wind path accessory 762 is provided with the width protuberance (extension) 763 larger than the width of the left and right directions of the opening portion of the U-shaped of the width of the left and right directions of recess 440 or the 2nd wind path accessory 764, block the opening portion of the 2nd wind path accessory 764 or recess 440 by this protuberance (extension) 763 with roughly air-tight state and form cold air wind path 760, and can utilize protuberance (extension) 763 that the 1st wind path accessory 762 can be fixed to protuberance 450 or the 2nd wind path accessory 764 removably.At this, as long as the 1st wind path accessory 762 can block the opening portion of the 2nd wind path accessory 764 to guarantee cold air wind path, as long as the opening portion of the 2nd wind path accessory therefore only can be blocked, without the need to blocking recess 440, if but the opening portion of recess 440 is blocked, then the installation of the 1st wind path accessory 762 can improve, and in addition, aesthetic appearance also improves.

At this, the cold air wind path accessory (such as the 1st wind path accessory 762 or the 2nd wind path accessory 764 etc.) forming cold air wind path 760 can also use as the strengthening part of the intensity for improving casing.When think casing intensity or gear housing rigidity (such as torsional strength or buckling strength etc.) more weak, as long as the 1st wind path accessory 762 or the 2nd wind path accessory 764 are used as strengthening part to increase casing intensity (gear housing rigidity).Under the 1st wind path accessory or the 2nd wind path accessory 764 are resinous situation, as long as have the predetermined thickness of the degree that can obtain casing intensity, if but wanted thickness thinning, may not be resin-made and be the metal (can be such as and the metal that the phase such as copper, aluminium specific thermal conductivity is little, heat-proof quality is good) that thermal conductivity is little.In addition, the 1st wind path accessory 762 or the 2nd wind path accessory 764 in the width direction or above-below direction rib etc. is set to improve torsional strength, bending strength.When the intensity of heat insulating box 700 or rigidity no problem time, also the 2nd wind path accessory 764 can be omitted, recess 440 is directly used as the back face wall of cold air wind path 760, side walls, and arranges the 1st wind path accessory 762 in the mode of the opening portion covering recess 440.

When recess 440 is directly used as the back face wall of cold air wind path 760, side walls, without the need to arranging the 2nd wind path accessory 764, therefore, it is possible to obtain structure simple and the heat insulating box 700 of low cost, refrigerator 1.Now, 1st wind path accessory 762 is set in the mode covering recess 440, the protuberance (extension) 763 of the 1st wind path accessory 762 can be fixed at protuberance 450 removably, by protuberance (extension) 763 is directly fixed to protuberance 450, the intensity of casing is also improved.By being used as the cover covering recess 440 by the 1st wind path accessory 762, recess 440 can utilize as cold air wind path 760.At this, can thicken the 1st wind path accessory 762 thickness of slab or arrange rib etc. improve rigidity using as strengthening part use, heat insulating box intensity can be improved.

Fig. 5 is the sectional elevation of another refrigerator of embodiments of the present invention 1, is sectional elevation when cutting refrigerator with the face vertical with the above-below direction of refrigerator 1.In Figure 5, equal with Fig. 1 ~ Fig. 4 part is marked with same-sign and omits the description.

In Figure 5, recess 440 is used as cold air wind path 760 identically with Fig. 4.

That is, form recess 440 by the side 452 of protuberance 450 and back face wall 730, formed back face wall 730 inner face (storeroom side) interior case 750 and formed back face wall 730 outside outer container 710 between be provided with the Vacuumed insulation panel 400 of tabular.At this, although do not illustrate, forming the Vacuumed insulation panel 400 that tabular also can be set between the interior case 750 of inner face (storeroom side) of sidewall 790 and the outer container 710 of the outside of formation sidewall 790.Be located at the cold air wind path 760 of back face wall 730 or recess 440, by there is the 1st wind path accessory 762 as cap assembly of aesthetic appearance and being located at the rear side (interior case 750 side) of the 1st wind path accessory 762 and the 2nd wind path accessory 764 with thermal insulation is formed, be configured in recess 440.This 1st wind path accessory 762 as cap assembly or the 2nd wind path accessory 764 have installation portion (holding section), by being embedded in the installation portion (holding section) of protuberance 450 or back face wall 730 setting or making installation portion engage with each other by fixed parts such as screws, thus be installed to protuberance 450 or back face wall 730.

Cold air wind path 760 is made up of the 1st wind path accessory 762 as cover in the storeroom side opening portion in the storeroom side opening portion or recess 440 that are arranged to covering the 2nd wind path accessory 764 and recess 440 or the 2nd wind path accessory 764, above-mentioned 2nd wind path accessory 764 be incorporated in recess 440 at least partially or all, the 1st wind path accessory 762 is fixed or is held in the end face 451 of front face side or the wind path side members 766 of the 2nd wind path accessory 764 of protuberance 450.In the present embodiment, the size of the stage portion 775 formed by the extension 763 of the 1st wind path accessory 762 is less, therefore the stage portion 775 being difficult to the side formed at the extension 763 by the 1st wind path accessory 762 arranges cool-air feed mouth 768, thus cool-air feed mouth (cold air blow-off outlet) 768 is only located at the front face side of the 1st wind path accessory 762.But, due to the thickness of the protuberance (extension) 763 of the 1st wind path accessory 762 can be reduced, the size of stage portion 775 therefore can be reduced.Therefore, the depth direction length in storeroom can increase the amount that stage portion 775 reduces, and can increase the storage volume in storeroom.

At this, the shape as the 1st wind path accessory 762 of cover can be tabular as shown in Figure 4, Figure 5, also can be the curved (such as arc-shaped or arched door shape etc.) outstanding to storeroom side.When 1st wind path accessory 762 is curved, the opening direction of cool-air feed mouth 768 can be made not to be only front direction in storeroom, also can arrange at incline direction by being arranged on curvature portion, the free degree arranging the position of cool-air feed mouth 768 improves, and therefore can cool in storeroom equably.

2nd wind path accessory 764 can fixed or after being held in recess 440, the 1st wind path accessory 762 is being fixed or is being held in end face 451 or the 2nd wind path accessory 764 of the front face side of protuberance 450.Also can under the state the 2nd wind path accessory 764 fixed in advance or is held in the 1st wind path accessory 762 and is integrally formed, the assembly of the 1st wind path accessory 762 and the 2nd wind path accessory 764 be received or be configured in recess 440, the protuberance (extension) 763 of the 1st wind path accessory 762 is fixed or is held in the end face 451 of protuberance 450(such as front face side).So, the protuberance 450 in storeroom is installed under the state that can fix at the 2nd wind path accessory 764 or be held in the 1st wind path accessory 762 and define cold air wind path 760, therefore assembling easily, and also easily pull down (assembly that can be formed cold air wind path 760 by the 1st wind path accessory 762 and the 2nd wind path accessory 764), be therefore easy to the assembly of cold air wind path 760 to be installed to (such as protuberance 450) in storeroom removably.

In addition, between Vacuumed insulation panel 400, sandwiched main purpose is in the recess 440 of the bonding bonding agent as the 1st sandwiched parts (can be the foaming heat insulation part with self-adhesiveness), the thickness of the 1st sandwiched parts between interior case 750 and Vacuumed insulation panel 400 and bonding agent (can be the foaming heat insulation part with self-adhesiveness) is less, therefore suppose cold air wind path 760(the 1st wind path accessory or the 2nd wind path accessory 764, or the assembly etc. of the 1st wind path accessory and the 2nd wind path accessory) when being installed to recess 440, likely because damaging Vacuumed insulation panel 400 for fixing screw etc.But in the present embodiment, cold air wind path 760 is installed on protuberance 450, therefore cold air wind path 760 can not be installed to and the recess 440 of Vacuumed insulation panel 400 position in opposite directions or interior case 750, thus the outsourcing material etc. of Vacuumed insulation panel 400 can not be damaged, can obtain that reliability is high, the decline of heat-proof quality or few heat insulating box, refrigerator, the equipment of deterioration.

At this, as cold air wind path 760, if the 1st wind path accessory 762 is installed to protuberance 450 in the mode covering recess 440, even if then do not arrange the 2nd wind path accessory 764 can form cold air wind path 760 yet, thus can obtain that accessory number is few, low cost, easily assembling and high heat insulating box, the refrigerator of reliability.

(recess is used as cold air wind path (three))

Fig. 6 is the sectional elevation of another refrigerator of embodiments of the present invention 1, is sectional elevation when cutting refrigerator with the face vertical with the above-below direction of refrigerator 1.In figure 6, equal with Fig. 1 ~ Fig. 5 part is marked with same-sign and omits the description.

In figure 6, form recess 440 by the side 452 of protuberance 450 and back face wall 730, formed back face wall 730 inner face (storeroom side) interior case 750 and formed back face wall 730 outside outer container 710 between be provided with the Vacuumed insulation panel 400 of tabular.In addition, although do not illustrate, the Vacuumed insulation panel 400 that tabular also can be set between the interior case 750 of inner face (storeroom side) of sidewall 790 and the outer container 710 of the outside of formation sidewall 790 is being formed.Be located at the cold air wind path 760 of back face wall 730 or recess 440, by there is the 1st wind path accessory 762 as cap assembly of aesthetic appearance and being located at the rear side (interior case 750 side) of the 1st wind path accessory 762 and the 2nd wind path accessory 764 with thermal insulation is formed, be configured in recess 440.This 1st wind path accessory 762 as cap assembly or the 2nd wind path accessory 764 have installation portion (holding section), be located at the installation portion (holding section) of back face wall by embedding or by fixed parts such as screws, installation portion engaged with each other, thus being installed to back face wall 730.In the drawings, space 770 is provided with between the sidepiece (side) 766 and the side (side) 452 of protuberance 450 of cold air wind path 760, this space 770 can use as storage space, therefore, it is possible to increase the storage volume of the collecting article in storeroom (such as refrigerating chamber 2).

In figure 6, the 2nd wind path accessory 764 forming cold air wind path 760 be the U-shaped with opening portion relative to the cross sectional shape of the flow direction (such as the above-below direction of refrigerator 1) of cold air, is arranged at (recess 440 being configured at the storeroom back side is interior) in the storeroom of refrigerator 1 to make the opening portion of this U-shaped towards the mode in the direction, the back side of refrigerator 1.To be pressed into by the 1st wind path accessory 762 at the opening of the U-shaped of the 2nd wind path accessory 764 and to be formed by fixing for the 1st wind path accessory 762 or be held in protuberance 450 under state that in recess 440, case 750 abuts, thus form cold air wind path 760 by the 2nd wind path accessory 764 and interior case 750.At this, when 1st wind path accessory 762 is made up of the parts (such as styrene or porous part etc.) with heat insulating function, do not need the 2nd wind path accessory 764, therefore can form cold air wind path 760 by the 1st wind path accessory 762 and interior case, the refrigerator of low cost, equipment can be obtained.At this, the cross section of the flow direction relative to cold air of the 2nd wind path accessory 764 has the opening of U-shaped, but may not be U-shaped, as long as cold air wind path can be formed, therefore, can be square or ellipticity relative to the cross sectional shape of the flow direction of cold air, as long as cold air wind path can be formed in inside.The cross sectional shape of inner cold air wind path also can be square or ellipticity.Cold air wind path be circular or elliptical shape time flow path resistance little, efficiency is high, in addition, compare the circular length that can reduce depth direction at the elliptical shape that width is elongated, therefore, it is possible to reduce to the overhang in storeroom, storage volume can be increased.

At this, case 750 in recess 440 can be formed by the 1st wind path accessory 762 or the 2nd wind path accessory 764 are directly fixed or be held in, form cold air wind path 760, also as shown in Figure 4 protuberance (extension) 763 can be set at the 1st wind path accessory 762, and make this protuberance 763 stretch out longer than the situation of Fig. 4, thus make protuberance (extension) 763 can cross over space 770 and be fixed to protuberance 450.Now, different according to the place of fixed salient (extension) 763, likely because protuberance 763 makes the storage volume reducing in space 770, therefore, if make protuberance (extension) 763 stretch out (leap) to being located at fixing near the upper and lower top wall 740 of cold air wind path 760 or underside wall 780 or the partition wall 24 separated between storeroom or shelf 80 or being held in protuberance 450, then can make the minimizing of storage volume less (high collecting article can be suppressed to encounter protuberance (extension) 763 and situation about cannot receive).

At this, the accessory (the 1st wind path accessory or the 2nd wind path accessory) forming cold air wind path 760 can directly to fix or be held near the top wall 740 setting up and down of cold air wind path 760 or near underside wall 780 or to storeroom between near the partition wall 24 separated or sidewall 790.(when such as protuberance 763 is located at the below of the above-below direction substantial middle in space 770 or substantial middle, when receiving high collecting article in space 770, collecting article is likely encountered protuberance 763 and cannot receive, if to be therefore located near top wall 740 place that (or near underside wall 780 or near the partition wall 24 separating between storeroom) etc. is difficult to become obstruction, even if collecting article to be accommodated in space 770, protuberance 763 is also difficult to become obstruction, and can increase storage volume.）

In addition, cover i.e. the 1st wind path accessory 762 at least covering the part at the back side in storeroom can possess: formed cold air wind path 760 at least partially or cover the wind path cover portion at least partially of cold air wind path 760; From wind path cover portion, (left and right directions or sidewall 790 direction) is stretched out and is covered the cover portion, the back side at least partially of back face wall 730 or recess 440 in the width direction; And be connected with cover portion, the back side or form with cover portion, the back side and cover the cover portion, side at least partially of sidewall 790.Further, the back side portion of covering can be fixed or be held in and to form in back face wall 730 or recess 440 or protuberance 450 case 750 etc. and install.Or, also the side portion of covering can be fixed or is held in and to form in sidewall 790 or protuberance 450 case 750 etc. and install.So, can cover back face wall 730, sidewall 790, protuberance 450 at least partially by the 1st wind path accessory 762 as cover, therefore aesthetic appearance raising, assembleability also improve.

In addition, cover i.e. the 1st wind path accessory 762 at least covering the part at the back side in storeroom can possess: formed cold air wind path 760 at least partially or cover the wind path cover portion at least partially of cold air wind path 760; From wind path cover portion, (left and right directions or sidewall 790 direction) is stretched out and is covered the cover portion, the back side at least partially of back face wall 730 or recess 440 in the width direction; And be connected with wind path cover portion or be integrally formed with wind path cover portion and the partition wall 24(that the above-below direction covering back face wall 730 is arranged comprises roof 740 or underside wall 780) upper lower wall cover portion at least partially.Further, the back side portion of covering can be fixed or be held in and to form in back face wall 730 or recess 440 or protuberance 450 case 750 etc. and install.Or, also upper lower wall cover portion can be fixed or is held in be formed in back face wall 730 above-below direction arrange partition wall 24(comprise roof 740 or underside wall 780) interior case 750 etc. install.So, can cover back face wall 730, partition wall 24, roof 730, underside wall 780 at least partially by the 1st wind path accessory 762 as cover, therefore aesthetic appearance raising, assembleability also improve.

In cold air wind path 760 or formation cold air wind path 760 accessory (the 1st wind path accessory or the 2nd wind path accessory etc.), in the side of cold air wind path 760 or be provided with one or more for will to be generated by cooler 13 and the cool-air feed of flowing is to the cool-air feed mouth 768 in storeroom (such as refrigerating chamber 2, vegetable compartment 5, refrigerating chamber 6 etc.) in cold air wind path 760 etc. above, this cool-air feed mouth 768 is located at can the collecting article such as food of cold storage indoor, the position of reserve effectively.The cool-air feed mouth of side and cool-air feed mouth above can be same positions at the height and position of above-below direction, but can cool from the diverse location of height when the height and position that staggers is configured, therefore, it is possible to collecting article, the reserve such as Homogeneous cooling food efficiently.In addition, the height and position of the cool-air feed mouth 768 arranged in the side (right flank and left surface) of left and right also can be phase co-altitude, but can cool from the diverse location of height when the height and position that staggers is configured, therefore, it is possible to collecting article, the reserve such as Homogeneous cooling food efficiently.

In addition, the width dimensions, identical with Fig. 4, Fig. 5 at the setting position of heat insulating box or refrigerator of Vacuumed insulation panel 400.Namely, the filling stream of the thermal insulation barriers such as the width ratio of the left and right directions of the Vacuumed insulation panel 400 arranged in the back face wall 730 of refrigerator 1 is as little in the width between the storeroom inner surface 791,792 of the sidewall 790 of refrigerator 1, the polyurethane that the filling mouth 703,704 that can not block the polyurethane thermal insulation barriers arranged from the rear side at refrigerator 1 is filled.

At this, Vacuumed insulation panel 400 is configured at the position (position of the position that such as can not block the opening of filling mouth 703,704 or the inflow that can not intercept or hinder the thermal insulation barriers such as the polyurethane that flows into (such as sidewall 790) in heat insulating box from the opening of filling mouth 703,704 in sidewall 790 or in back face wall 730 etc.) that the filling mouth 703,704 comparing the thermal insulation barriers such as the polyurethane that arranges in the left and right end portions side at the back side of refrigerator 1 is not exposed to outside and is advisable.By being configured at the position being such as close to width central side (inner side) than the filling mouth (left filling mouth 703 and right filling mouth 704) of left and right, and above-below direction position and filling mouth 703, 704 nonoverlapping positions, can not intercept or hinder from filling mouth 703, 704 to the (space 315 between interior case 750 and outer container 710 in heat insulating box, such as, in sidewall 790, in back face wall 730 etc.) thermal insulation barriers such as the polyurethane of filling is to the filling in (space 315 between interior case 750 and outer container 710) in heat insulating box, lack of fill or the density that therefore can not produce thermal insulation barriers are not enough, the high performance heat insulating box that heat-proof quality can not decline can be obtained, refrigerator.

At this, Vacuumed insulation panel 400 and interior case 750 are via bonding agent (can be the foaming heat insulation part with self-adhesiveness) the directly bonding direct bonding site and the recess 440 that with bonding are main purpose, such as have the stage portion 776 of the projecting height amount of protuberance 450 relative to the strengthening part sandwiched position (such as protuberance 450) being filled with the strengthening parts such as hard polyaminoester, recess 440 caves in depth direction (rear side) relative to protuberance 450.Otherwise, outstanding to the front side of depth direction relative to the recess 440 as direct bonding site using the amount of stage portion 776 as the protuberance 450 at strengthening part sandwiched position.In addition, Vacuumed insulation panel 400 and interior case 750 are via the directly bonding direct bonding site of the bonding agent such as foaming heat insulation part of self-adhesiveness and recess 440, the step that the height (thickness) with cold air wind path 760 is measured, recess 440 caves in depth direction (rear side) relative to the front face side end 769 of cold air wind path 760.Otherwise the end face 769 of the front face side of cold air wind path 760 is outstanding to the front side of depth direction relative to direct bonding site with the amount of step.

As mentioned above, in the present embodiment, formed by interior case 750 and outer container 710 and possessing between interior case 750 and outer container 710 in the equipment such as heat insulating box, refrigerator, cold insulated cabinet, showcase of Vacuumed insulation panel 400, possessing: the direct bonding site (being recess 440 in the figure) Vacuumed insulation panel 400 be located in the back face wall 730 of indoor (such as in storeroom) directly being pasted interior case 750 by having the bonding agents such as the foaming heat insulation part of self-adhesiveness; And between Vacuumed insulation panel 400 and interior case 750 sandwiched for improving the strengthening part sandwiched position (in figure for protuberance 450) of the thermal insulation barriers 751 such as the polyurethane as strengthening part of the intensity of casing.At this, Vacuumed insulation panel 400 and outer container 710 by PUR or double faced adhesive tape etc. the 2nd bonding agent be directly pasted together.PUR or double faced adhesive tape etc. the 2nd bonding agent can apply or be pasted onto Vacuumed insulation panel 400 side or outer container 710 side in advance, therefore can the thickness of thinning bonding agent, thus preferably; But coating inequality may be produced or paste unequal, therefore between Vacuumed insulation panel 400 and interior case 750, preferably using the foaming heat insulation part with self-adhesiveness.

In addition, in the present embodiment, the width of such as strengthening part sandwiched position (such as protuberance 450) and direct bonding site (such as recess 440) the sustained height position in storeroom is arranged, direct bonding site (such as recess 440) between the strengthening part sandwiched position (such as protuberance 450) arranged by the left and right end portions of the width in storeroom and the strengthening part sandwiched position being located at left and right in the mode clipped by the strengthening part sandwiched position of left and right, and the left and right directions at the storeroom back side forms protuberance 450(strengthening part sandwiched position), the direct bonding site of recess 440(is formed) between protuberance 450.At this, recess 440 and protuberance 450 are from guaranteeing the intensity of casing or guaranteeing the angle of cold air wind path, and the roughly whole altitude range of the above-below direction preferably in storeroom is arranged.

So, with recess 440 position in opposite directions, make Vacuumed insulation panel 400 directly contact with outer container 710 via the 2nd bonding agent or abut, therefore between outer container 710 and Vacuumed insulation panel 400, do not need thermal insulation barriers, storeroom internal volume can be increased compared with during sandwiched thermal insulation barriers.In addition, at direct bonding site (such as recess 440), Vacuumed insulation panel 400 is made to contact with interior case 750 via the foaming binding agent with cementability or abut.In the present embodiment, at the configuration position (such as recess 440) of Vacuumed insulation panel 400, by Vacuumed insulation panel 400, there is heat-proof quality and intensity, therefore not needing between interior case 750 and Vacuumed insulation panel 400 is the thermal insulation barriers of main purpose with heat insulation, with with heat insulation be main purpose and sandwiched thermal insulation barriers time compared with can thinning wall thickness, therefore can increase storeroom internal volume.At this, when needing mobility as bonding agent, also can use the hard polyurethane foams etc. with self-adhesiveness, to make it foam after in two-phase state inflow space 315 thus to carry out bonding.

In the present embodiment, recess 440 can be utilized as the cold air wind path 760 blowed the cold air of cold storage indoor, therefore, it is possible to the recess 440 at the storeroom back side making the hand of user be difficult to touch is utilized effectively, thus the storage volume in storeroom can be used efficiently.In addition, use have predetermined intensity (bending strength, buckling strength) Vacuumed insulation panel 400 and by protuberance 450 in storeroom with predetermined width (preferably can guarantee the degree of torsional strength, buckling strength) when above-below direction is arranged continuously, heat insulating box 700, intensity needed for refrigerator 1 can be obtained, and guarantee the buckling strength of torsional strength, fore-and-aft direction or left and right directions, therefore, it is possible to obtain reliability high heat insulating box 700, refrigerator 1.In addition, as long as can obtain heat insulating box 700, intensity needed for refrigerator 1 guarantee the buckling strength of torsional strength, fore-and-aft direction or left and right directions, protuberance 450, without the need to arranging continuously at above-below direction, also can arrange a place or arrange many places intermittently.

In the present embodiment, in storeroom, the left and right end portions side (width end side) at the back side forms the protuberance 450 be made up of thermal insulation barriers 701 such as the polyurethane configured along the vertical direction, therefore can improve casing 700, the torsional strength of refrigerator 1, buckling strength by forming this protuberance 450.Therefore, casing 700 or refrigerator 1 is there will not be to be out of shape and the door of storage room (such as the refrigerating-chamber door 7 of rotary (radial type)) making to be located at before storeroom (such as refrigerating chamber 2) tilts, such as one side of the door (7A, 7B) of left and right tilts and causes the situation of dislocation when clamshell doors, therefore, it is possible to successfully carry out the opening and closing of door of storage room.In addition, the dislocation of the door of storage room of left and right can not be there is, therefore attractive in appearance.In addition, when drawer type door, different or inclination can not make the setting height(from bottom) of the track of the drawer type box body being located at storeroom (such as ice-making compartment 3, switch room 4, vegetable compartment 5, refrigerating chamber 6 etc.) inwall (sidewall of left and right) 791,792 because casing 700 is out of shape about, therefore, it is possible to successfully carry out the discrepancy of box body.

At this, in the present embodiment, the thermal insulation barriers such as the polyurethane of Vacuumed insulation panel 400, formation protuberance 450 need predetermined intensity, therefore Vacuumed insulation panel 400 uses the parts that Deflection Modulus of Elasticity is more than 20MPa, and the thermal insulation barriers such as polyurethane forming protuberance 450 uses Deflection Modulus of Elasticity to be greater than 60kg/m for more than 13.0MPa (being preferably more than 15MPa), density ³(be preferably 62kg/m ³parts above).Both casing intensity and heat-proof quality to be obtained by thermal insulation barriers such as polyurethane in the past, therefore from guaranteeing that the angle of casing intensity needs to make polyurethane thermal insulation barriers increase Deflection Modulus of Elasticity, if but increase Deflection Modulus of Elasticity as the characteristic of hard polyaminoester, then density increases, if density increases, heat-proof quality declines.Therefore, when polyurethane, in order to obtain predetermined heat-proof quality, being difficult to make Deflection Modulus of Elasticity be about more than 10MPa, therefore, the thickness of polyurethane cannot being made to be thinner than such as about 15mm.At this, the thickness of polyurethane is thinner, more can reduce the thickness of wall, increase storeroom internal volume, thus preferably.But, during in order to reduce the thickness of wall thickness and thinning polyurethane, the density of polyurethane increases, Deflection Modulus of Elasticity also increases, therefore, it is possible to increase casing intensity, but when density increases, heat-proof quality can worsen, and is therefore difficult to make the thickness of polyurethane to be thinner than predetermined value (such as 15mm).

In the present invention, Vacuumed insulation panel 400 uses Deflection Modulus of Elasticity greatly to the parts of more than 20MPa, therefore the part (casing or wall) of Vacuumed insulation panel 400 is being configured with, Vacuumed insulation panel 400 can be made to have both heat-proof quality and intensity, even if between outer container and interior case during the thermal insulation barriers such as filled polyurethane, at the position being configured with Vacuumed insulation panel, also bonding agent can be it can be used as to use without the need to being used as the thermal insulation barriers with heat insulation being main purpose by polyurethane.Therefore, the thermal insulation barriers such as polyurethane can be used as carrying out bonding bonding agent to Vacuumed insulation panel 400 and interior case 750 or Vacuumed insulation panel 400 and outer container 710, even if therefore reduce the thickness of polyurethane and to make the heat-proof quality of polyurethane decline also no problem.At this, by making the filling rate (Vacuumed insulation panel 400 is relative to the V/V shared by the space 315 between outer container 710 and interior case 750) of the covering rate of Vacuumed insulation panel 400 (the configuration area of Vacuumed insulation panel 400 is relative to the ratio of the surface area of casing 700, door) or Vacuumed insulation panel 400 large more than predetermined value, even if there is the position not configuring Vacuumed insulation panel 400, heat-proof quality, the intensity as heat insulating box 700 also can be guaranteed.

Therefore, between outer container 710 and interior case 750, the position of Vacuumed insulation panel 400 is configured with as shown in the embodiment in recess 440 grade, when be there is by Vacuumed insulation panel 400 both the intensity of casing 700 and heat-proof quality, between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, can as being that the bonding agent of main purpose is to use hard polyurethane foams with bonding, therefore can reduce the thickness of polyurethane, the decline of the heat-proof quality of polyurethane can not be considered.Therefore, even if reduce wall thickness because of the thickness of thinning hard polyurethane foams, make the heat-proof quality of hard polyaminoester decline, because the heat-proof quality of casing is born by Vacuumed insulation panel 400, so there is no problem.Thus, storeroom internal volume can be increased by the thickness of reduction polyurethane, reduction wall thickness.Wherein, can thinning wall thickness when any one party between outer container 710 and Vacuumed insulation panel 400 or between interior case 750 and Vacuumed insulation panel 400 uses the 2nd bonding agent such as PUR or double faced adhesive tape, therefore, it is possible to increase the volume in storeroom.

At this, the thickness of hard polyurethane foams when using as the bonding agent used between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750 is for below predetermined value or when being less than the thickness of Vacuumed insulation panel 400, wall thickness can be reduced, therefore, it is possible to increase the volume in storeroom.At this, for any one party between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750 use with bonding be the thickness of the hard polyurethane foams of main purpose be less than the thickness of Vacuumed insulation panel 400 time, the effect that can reduce wall thickness can be obtained.If the thickness sum of the thickness of the hard polyurethane foams between Vacuumed insulation panel 400 and outer container 710 and the hard polyurethane foams between Vacuumed insulation panel 400 and interior case 750 is less than the thickness of Vacuumed insulation panel 400, then can reduce wall thickness further, thus the volume in storeroom can be increased.

In the present embodiment, as the bonding agent used between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, use hard polyurethane foams, and make the thickness of polyurethane thin as far as possible.But, be not only between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, not arranging Vacuumed insulation panel 400 and only the position (in wall) of filled polyurethane also can use identical hard polyurethane foams.Do not arrange Vacuumed insulation panel 400 and only the position (part such as in wall or in protuberance) of filled polyurethane owing to there is not Vacuumed insulation panel 400, thus the thickness of hard polyaminoester can be made to increase the amount of thickness of Vacuumed insulation panel 400, therefore also can increase the insulating thickness of polyurethane.Therefore, compared with the thickness of the polyurethane of filling between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, the thickness of the polyurethane at the position that there is not Vacuumed insulation panel 400 can be increased, thus be configured with Vacuumed insulation panel 400 position polyurethane density compared with, the density of the polyurethane at the position not configuring Vacuumed insulation panel 400 can be reduced, therefore the heat-proof quality not configuring the polyurethane at the position of Vacuumed insulation panel 400 improves, and can guarantee predetermined performance.In addition, do not configuring the position of Vacuumed insulation panel 400, can increase the thickness of polyurethane, therefore casing intensity also improves.At this, in the present embodiment, in order to meet both casing intensity and heat-proof quality, the covering rate of Vacuumed insulation panel 400 (the configuration area of Vacuumed insulation panel 400 is relative to the ratio of the surface area of casing 700, door) or the filling rate (Vacuumed insulation panel 400 is relative to the V/V shared by the space 315 between outer container 710 and interior case 750) of Vacuumed insulation panel 400 large more than predetermined value.

In the present embodiment, by Vacuumed insulation panel 400, there is heat-proof quality, casing intensity, the thickness of polyurethane thermal insulation barriers therefore can be used to reduce and make the intensity of polyurethane thermal insulation barriers for Deflection Modulus of Elasticity is greatly to the parts of more than 13.0MPa (preferred more than 15MPa).In addition, the density of polyurethane thermal insulation barriers also can be used to be greater than 60kg/m ³(preferred 62kg/m ³parts above), therefore can reduce the thickness of polyurethane, also can reduce the wall thickness of heat insulating box 700.

In addition, in Fig. 4 ~ Fig. 8, protuberance 450 has as the function of strengthening part for maintaining or improve casing intensity, is also also used as the incorporating section of containing tube 720 or refrigerant piping 725 etc.In addition, the incorporating section that can will form the jut 910 of the 2nd recess 441 in Fig. 8 and be used for containing tube 720 or refrigerant piping 725 etc., also can filling-foam thermal insulation barriers etc. and using as strengthening part.One side of protuberance 450 or jut 910 can be used as the incorporating section of containing tube 720 or refrigerant piping 725 etc., also protuberance 450 and jut 910 both sides can be used as the incorporating section of containing tube 720 or refrigerant piping 725 etc.When like this protuberance 450 or jut 910 being used for the incorporating section of containing tube 720 or refrigerant piping 725 etc. or using as casing rib, being used for the incorporating section of containing tube 720 or refrigerant piping 725 etc. without the need to arranging separately, can obtaining that structure is simple, low cost and the heat insulating box of high strength, refrigerator, equipment etc.

Protuberance 450 is located at the corner part (turning, side or turning, both sides) of the side of the width at the storeroom back side.Protuberance 450, at the width of storeroom, one end is connected with the predetermined position 797 of the sidewall 790 forming storeroom, the other end of width is connected to and the predetermined position 798 of Vacuumed insulation panel 400 in the back face wall 730 of the position of the overlapping predetermined length X of width, is filled with the foaming heat insulation parts such as hard polyaminoester in inside.Like this protuberance 450 is extended to partly overlapping position (position of overlap length X) at the width of Vacuumed insulation panel 400, thus Vacuumed insulation panel 400 is integrally formed via the polyurethane in the polyurethane in protuberance 450 and sidewall 790, sidewall 790 is firmly formed together with Vacuumed insulation panel 400, hard polyaminoester integratedly with back face wall 730, and the intensity of casing 700 is improved.Now, make the hard polyurethane foams be filled in sidewall 790 also fill to the space between Vacuumed insulation panel 400 and interior case 750 and carry out foaming just can easily tackle.At this, protuberance 450 is located at corner part, cross sectional shape is square, rectangle, roughly triangular shape, arc-shaped or arched door shape, and highlightedly by shaping for interior case 750 in storeroom, by filling between case 750 and outer container 710 in this protuberance 450 of formation or arranging hard polyurethane foams etc., and form protuberance 450 using as strengthening part.At this, the packing material such as polyurethane of filling to the space between outer container 710 and interior case 750 is by considering to arrange the part of Vacuumed insulation panel 400 and not arranging the heat-proof quality of casing 700 of part of Vacuumed insulation panel 400, the adhesive strength of interior case 750, Vacuumed insulation panel 400 and outer container 710, the intensity (rigidity) etc. of casing 700 is determined.In the present embodiment, use hard polyurethane foams as packing material.

Predetermined length X overlapping with Vacuumed insulation panel 400 is arranged in one end as back face wall 730 side of the protuberance 450 of intensity portion (rib), therefore by be filled in hard polyurethane foams in protuberance 450 by Vacuumed insulation panel 400 and interior case 750 bonding securely, Vacuumed insulation panel 400 is also connected with sidewall 790 securely via polyurethane.In addition, the corner part of the width at the storeroom back side forms protuberance 450 outstanding in storeroom, even if be therefore configured with the lower thickness of the hard polyurethane foams of the recess 440 of Vacuumed insulation panel 400, also can suppress the reduction of heat-proof quality, and improve casing intensity by protuberance 450 and Vacuumed insulation panel 400.In addition, do not configuring the wall (such as sidewall 790, partition wall 24 etc.) of Vacuumed insulation panel 400, by increasing configuration area, the excretion volume (increasing covering rate, the filling rate of Vacuumed insulation panel) of Vacuumed insulation panel, the heat-proof quality as heat insulating box comprising the wall not configuring Vacuumed insulation panel 400 also can be guaranteed.In addition, protuberance 450 extends to Vacuumed insulation panel 400 in the overlapping position of width, and therefore the recess (440,441) of Vacuumed insulation panel 400, sidewall 790, back face wall can be integrally formed (or shaping), and casing intensity is improved.

In addition, pipe 720, refrigerant piping 725 that storage controls the lead-in wire such as distribution, power line can be configured in protuberance 450, now, except utilizing protuberance 450 to improve except casing intensity, pipe 720, refrigerant piping 725 also can utilize as the strengthening part for improving casing intensity.Therefore, not needing to configure reinforcement accessory separately to improve casing intensity, being therefore low cost, and the reinforcement of heat insulating box 700 can be carried out, therefore, it is possible to improve the casing intensity of heat insulating box.In addition, strengthening part can be configured in protuberance 450, therefore aesthetic appearance also improves.Therefore, it is possible to obtain low cost, reliability high and heat insulating box, refrigerator that aesthetic appearance is good.

At this, the predetermined length X of the width that protuberance 450 is overlapping with Vacuumed insulation panel 400 is longer, the hard polyaminoester in protuberance 450 and Vacuumed insulation panel 400 can the length (or cementation area) of cementation (or maintenance) larger, casing intensity can be improved; If but long, then protuberance 450 becomes large to the overhang (volume outstanding in storeroom) in storeroom, and the capacity in storeroom diminishes, and therefore can be below 200mm, is preferably below 180mm.In addition, if the predetermined length X of the width that protuberance 450 is overlapping with Vacuumed insulation panel 400 is too short, the cement strength of the hard polyaminoester then in Vacuumed insulation panel 400 and protuberance 450 diminishes, the intensity of casing reduces, in addition, the packing materials such as the hard polyaminoester length X overlapping with Vacuumed insulation panel 400 than 30mm in short-term, can increase heat leak along the surface of Vacuumed insulation panel 400.Namely, the packing materials such as hard polyaminoester relative to the part of Vacuumed insulation panel 400 overlap length X than 30mm in short-term, heat leak can be caused to become large because of the heat bridge from the surface of outwardly case 710 side (rear side) of case 750 side (storeroom side) in Vacuumed insulation panel 400, heat-proof quality reduces, therefore be advisable for more than 30mm, be preferably more than 40mm.Therefore, the length X of Vacuumed insulation panel 400 and protuberance 450 overlap, lower limit is that more than 30mm (preferred more than 40mm) is advisable, the upper limit is that below 200mm (preferred below 180mm) is advisable, and is be advisable in about less than 1/3 of sidewall 790 spacing (distance between storeroom inner surface 791,792) of heat insulating box 700.(when setting the outer width of refrigerator 1 as about 600mm, if set the thickness of sidewall 790 as 30mm, then the inner surface spacing of sidewall 790 is about 540mm, therefore overlap length X be about 540mm less than 1/3, namely below 180mm be advisable.）

In the present embodiment, be illustrated so that Vacuumed insulation panel 400 is configured at back face wall, but also can be configured at sidewall 790, also Vacuumed insulation panel 400 can be configured at back face wall and sidewall 790 both sides.Now, according to the reason same with back face wall side, too, the lower limit of the length of Vacuumed insulation panel 400 and protuberance 450 overlap is that more than 30mm (being preferably more than 40mm) is advisable to side wall side, and the upper limit is that below 200mm (being preferably below 180mm) is advisable.(length of Vacuumed insulation panel 400 and protuberance 450 overlap is preferably more than the 1st predetermined value (such as 30mm, preferred 40mm) the 2nd predetermined value width of the such as Vacuumed insulation panel 400 (about 1/3) below relative to the width of Vacuumed insulation panel 400.When 1st predetermined value is less than 30mm, the length X of the part that the packing materials such as hard polyaminoester are overlapping with Vacuumed insulation panel 400 shortens, to cause because of the heat bridge on the surface of the outwardly case side (rear side) of the inner box side (storeroom side) from Vacuumed insulation panel 400 that heat leak becomes large, heat-proof quality reduction, and the length of protuberance and Vacuumed insulation panel 400 overlap is too short, the intensity of casing reduces, and therefore the 1st predetermined value is preferably more than 30mm (more preferably more than 40mm).In addition, when the 2nd predetermined value exceedes 1/3 of the width of Vacuumed insulation panel 400, the width of recess 440 or the 2nd recess 441 diminishes, and cold air wind path 760 cannot guarantee predetermined size, and therefore the 2nd predetermined value is preferably less than 1/3.）

At this, Vacuumed insulation panel 400 can be configured at roof 740 or underside wall 780 or at corner part, protuberance 450 is arranged to the partition wall 24 separated between storeroom.The protuberance that formed of the corner part of wall 730 and roof 740 and the length of Vacuumed insulation panel 400 overlap overleaf, or the protuberance that formed of the corner part of wall 730 and underside wall 780 and the length of Vacuumed insulation panel 400 overlap overleaf, or the protuberance that formed of the corner part of wall 730 and partition wall 24 and the length of Vacuumed insulation panel 400 overlap overleaf, or the protuberance formed at the corner part of sidewall 790 and roof 740 and the length of Vacuumed insulation panel 400 overlap, also as described above, lower limit is preferably more than 30mm (being more preferably more than 40mm), the upper limit is preferably below 200mm (being more preferably below 180mm).

As mentioned above, the length X of the width of part overlapping with Vacuumed insulation panel 400 for one end of the protuberance 450 as intensity portion is set in preset range, increases the recess 440 of formation or the space 770 between the space 770(jut 910 formed between protuberance 450 and the 2nd recess and protuberance 450 between the protuberance 450 of left and right with therefore can can't harm casing intensity and heat-proof quality).Therefore, predetermined casing intensity and predetermined heat-proof quality can be guaranteed, and increase case internal volume, increase the space 770 of the reserve accommodation space as food etc., therefore can increase the storage volume in storeroom, user's refrigerator easy to use, equipment can be obtained.

Formed as the interior case 750 of the orbit portion end (orbit portion protuberance) 757 outstanding to storeroom side of track mounting portion and Vacuumed insulation panel 400(or outer container 710) between the thermal insulation barriers 701(such as hard polyurethane foams such as polyurethane of filling) density be greater than 60kg/m ³time, intensity as the orbit portion end 757 of track component mounting portion is improved, even if therefore receive weight at box body 520, track component mounting portion and the orbit portion protuberance 757 of mounting track component 810 also can not be out of shape, therefore stably can carry out the discrepancy of box body 520, the high refrigerator of reliability, equipment can be obtained.

At this, track component 810 can be located at sidewall 790, also can be located at the partition wall (being included in the partition wall and the bottom surface of formation storeroom or partition wall 24 above or underside wall 780 or roof 740 that arrange between storeroom and storeroom) of the storeroom of configuration track component 810.That is, the rail supported portion 820 of supporting track parts 810 can be located at (or being placed in) partition wall (comprising partition wall 24 or roof 740 or underside wall 780).If like this rail supported portion 820 of supporting track parts 810 to be located at the partition wall 24 of storeroom, just without the need to arranging fixed part 735 at sidewall 790, therefore the thickness of the Vacuumed insulation panel 400 in sidewall configuration can be increased, in addition, the thickness of the thermal insulation barriers 701 such as the polyurethane of filling between Vacuumed insulation panel 400 in sidewall 790 and interior case 750 can be reduced.Therefore, the volume of volume in storeroom or box body 520 can be increased.

At this, when rail supported portion 820 is located at partition wall, in partition wall 24 or underside wall 780 or roof 740, be not advisable at the position configuration Vacuumed insulation panel 400 arranging track fixed part 735.In addition, if arrange for the strengthening part of the fixed parts such as hold-down screw in the position arranging track fixed part 735, then fixed part constant intensity or keep intensity to be improved.In addition, when filling between Vacuumed insulation panel 400 and the profile parts forming partition wall or apply or configure the thermal insulation barriers such as hard polyurethane foams or foam styrene, if make the density of thermal insulation barriers be greater than 60kg/m ³, then fix or keep the fixed part of track component 810 or the maintenance of strengthening part or constant intensity to be improved, therefore reliability improves.

Be illustrated by the fixing situation such as screw (head of screw as the screw of fixed part 735 is located at storeroom 2,3,4,5,6 side, situation between the orbit portion 755 of interior case 750 and Vacuumed insulation panel 400 is located in the threaded portion of fixed part 735) inside storeroom using the orbit portion 755 of interior case 750 above.But the screw 735 of fixed part also can be made to give prominence to and fix in the laterally therein storeroom 2,3,4,5,6 of sidewall 790, now, between the orbit portion 755 that head of screw is located at Vacuumed insulation panel 400 and interior case 750 (orbit portion 755 or the thermal insulation barriers 701 such as track strengthening part 731 or polyurethane are fixed in threaded portion), even if but in this case, because the density of polyurethane is greater than 60kg/m ³therefore the thermal insulation barriers 701 such as fixed part 735 and the polyurethane etc. such as intensity increase, the screw thermal insulation barriers 701 of polyurethane 701, interior case 750 and polyurethane constant intensity or keep intensity to increase, thus the dislocation of the distortion of interior case etc., strengthening part 731, screw loosen etc. suppressed, box body 520 grade can be made to pull out swimmingly (can come in and go out swimmingly).

In embodiments of the present invention, the thickness of the foaming heat insulation part (such as hard polyurethane foams) in position in opposite directions, the position arranging track component of sidewall 790 between case 750 and Vacuumed insulation panel 400 is set as below 11mm (being preferably less than 10mm), thus the Deflection Modulus of Elasticity of polyurethane can be increased, therefore can maintain wall intensity while thinning wall thickness.In addition, when the thickness of the foaming heat insulation part (such as hard polyurethane foams) in position in opposite directions, the position arranging track component of sidewall 790 between case 750 and Vacuumed insulation panel 400 is set as below 6mm, the Deflection Modulus of Elasticity of polyurethane can be increased further, therefore can maintain wall intensity while thinning wall thickness.

In addition, by the thickness of foaming heat insulation part/(thickness of the thickness+Vacuumed insulation panel of foaming heat insulation part) is set as less than 0.3, thinning wall thickness the composite guide heating rate of composite component foaming heat insulation part and Vacuumed insulation panel combined can be reduced, even if therefore also can improve heat-proof quality.

In addition, by making the density after polyurethane foam be greater than 60kg/m ³, can maintain wall intensity while thinning wall thickness.

As above, in embodiments of the present invention, the thickness of the foaming heat insulation part (such as hard polyurethane foams) in position in opposite directions, the position arranging track component of sidewall 790 between case 750 and Vacuumed insulation panel 400 is below 11mm (being preferably less than 10mm), the thickness of foaming heat insulation part/(thickness of the thickness+Vacuumed insulation panel of foaming heat insulation part) is set as less than 0.3, and makes the density after polyurethane foam be greater than 60kg/m ³time, can further maintain wall intensity while thinning wall thickness.At this, the thickness of the foaming heat insulation part in above formula is the thickness of polyurethane, therefore, as the thickness of foaming heat insulation part, can be the thickness R of the thermal insulation barriers 701 such as the thickness Q of thermal insulation barriers 701 or the polyurethane between Vacuumed insulation panel 400 and strengthening part 731 such as the thickness P of the thermal insulation barriers 701 such as the polyurethane of filling between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750 or the polyurethane of filling between Vacuumed insulation panel 400 and interior case 750.Such as, when making the thickness of foaming heat insulation part be the thickness R of the thermal insulation barriers 701 such as polyurethane between Vacuumed insulation panel 400 and strengthening part 731, the thickness by the thickness R+ Vacuumed insulation panel of the thickness R/(foaming heat insulation part of foaming heat insulation part) be set as less than 0.3.Equally, when making thickness be P or Q, thickness R is replaced as P or Q.In addition, the thickness of the polyurethane shown in Figure 17, Figure 18, Figure 19 equally also can be the thickness R of the thermal insulation barriers 701 such as the thickness Q of thermal insulation barriers 701, the polyurethane between Vacuumed insulation panel 400 and strengthening part 731 such as the thickness P of the thermal insulation barriers 701 such as the polyurethane of filling between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750, the polyurethane of filling between Vacuumed insulation panel 400 and interior case 750.

In addition, if make the Deflection Modulus of Elasticity of Vacuumed insulation panel 400 be more than 20MPa, can further thinning wall thickness.At this, can not be that track component is fixed to sidewall 790, but the partition wall 24 of the underside wall 780 be fixed near sidewall 790 or bottom surface or upper wall (roof) 740 or partition wall 24 above.At this, the position that the fixed parts such as screw are set in opposite directions in do not configure Vacuumed insulation panel 400 between case 750 and outer container 710 time, wall or partition wall that the underside wall 780 of fixed part or partition wall 24 below or roof 740 or partition wall above 24 preferably do not contact with outer gas are set.Reduce the position that Vacuumed insulation panel 400 is not set at the wall contacted with outer gas (such as sidewall 790, roof 740, back face wall 730, underside wall 780 etc.) as far as possible, the loss because heat leak causes can be reduced, therefore, it is possible to obtain high performance heat insulating box, refrigerator, equipment.Thereby, it is possible to the configuration area of the Vacuumed insulation panel 400 of increase back face wall 730, sidewall 790, therefore, it is possible to increase covering rate or the filling rate of the Vacuumed insulation panel 400 in heat insulating box 700.

At this, the heat insulating box 700 of present embodiment 1, mainly to bear this prior art thought of heat insulating function different from the hard polyurethane foams in heat insulating box 700, and it bears heat-proof quality and this new technological thought of casing intensity based on making Vacuumed insulation panel 400 in the part being configured with Vacuumed insulation panel 400.Therefore, the heat insulating box 700 of present embodiment 1 make the Vacuumed insulation panel 400 in the wall that formed between outer container 710 and interior case 750 in space 315 filling rate (volume of Vacuumed insulation panel 400 relative to space 315 in the wall formed between outer container 710 and interior case 750 cumulative volume shared by ratio) for predetermined value more than (being such as more than 40% (being preferably more than 45%)).At this, the volume that the filling rate of Vacuumed insulation panel 400 also comprises Vacuumed insulation panel 400 relative to space in the door formed between the external door panel of profile of door and door inner panel volume shared by ratio and the filling rate of door.

In prior art, with make Vacuumed insulation panel relative to outer container 710 or interior case 750 surface area shared by the mode that is in predetermined scope of area ratio (covering rate) configure Vacuumed insulation panel, and do not consider the impact of the thickness of Vacuumed insulation panel 400, therefore make the thickness of the Thickness Ratio Vacuumed insulation panel 400 of hard polyurethane foams large, to be had the intensity of heat insulating box by hard polyaminoester.The covering rate of Vacuumed insulation panel 400 to be increased to improve the heat-proof quality of casing in prior art, but the filling rate not increasing Vacuumed insulation panel 400 improves heat-proof quality and casing intensity both sides, therefore the filling rate of Vacuumed insulation panel 400 less (filling rate in such as existing refrigerator is about 20%), there is the situation that heat-proof quality does not improve, and casing intensity-dependent is in hard polyurethane foams.In the present embodiment, to consider the mode of the filling rate of the thickness of Vacuumed insulation panel 400 to configure Vacuumed insulation panel 400, therefore heat-proof quality can not do not improved as prior art.Be more than predetermined value (such as more than 40%) by making the filling rate of Vacuumed insulation panel 400, heat-proof quality is improved, and can while meeting casing intensity, heat-proof quality thinning wall thickness, therefore, it is possible to increase storeroom internal volume, the storeroom internal volume required by product can be set as more than predetermined capacity.That is, suitably can set the length of Vacuumed insulation panel 400, width, thickness, configuration position, can wall thickness be reduced, can correspondingly increase storeroom internal volume.

By increasing the filling rate of the Vacuumed insulation panel 400 in space 315 so compared to existing technology, heat-proof quality is increased compared to existing technology, even if therefore the wall thickness of thinning heat insulating box 700 compared to existing technology, also can guarantee that heat-proof quality is more than the equal extent of prior art.

(other of the 1st wind path accessory are formed)

As mentioned above, in embodiments of the present invention, the width length of the 1st wind path accessory 762 of a part for such as, formation cold air wind path 760 shown in Fig. 4, Fig. 5, Fig. 6, Fig. 8 etc. is less than the width of recess 440, is fixed at the jut 910 etc. of protuberance 450 or the 2nd recess 441 or formation the 2nd recess 441 or is kept by the fixed parts such as screw or hooking structure or embedded structure etc.At this, the width length of the 1st wind path accessory 762 of a part for formation cold air wind path 760 can be made to reach the inner face of sidewall 790 in the mode of the part covering back face wall 730 or sidewall 790 and fixed by the fixed parts such as screw or hooking structure or embedded structure etc. by the 1st wind path accessory 762 or remain to the inner face of sidewall 790.Certainly, the inner face of sidewall 790 not only can be fixed or remain to the 1st wind path accessory 762, can also be fixed by fixed part or hooking structure or embedded structure etc. or be remained to jut 910, recess 440, protuberance 450 etc.

In addition, if make the width length of the 1st wind path accessory 762 of a part for formation cold air wind path 760 reach sidewall 790 inner face thus not only cover the 2nd recess 441 also cover recess 440, protuberance 450 at least partially or all, then the 1st wind path accessory 762 can be also used as the Appearance Panel, can the back face wall of covering chamber's (such as storeroom) or the inner face of sidewall at least partially or all, the cap assembly of the 1st wind path accessory 762 as the part covering the back side or side can be used.Therefore, by when being located at the 1st wind path accessory 762 to indoor supply from the supply port of the cold air of cold air wind path 760, the free degree of configuration can be improved, collecting article efficiently in cooling chamber, in addition, 1st wind path accessory 762 can use another parts different from interior case 750, and therefore easily can change shape or color or carry out all processing, coating or literature record etc., functional, aesthetic appearance is improved.When the 1st wind path accessory being also used as the Appearance Panel and using as cap assembly, be formed as roughly U-shaped and cover the back face wall 730 of forming chamber and the inner face of sidewall 790 at least partially or whole inner faces of wall be advisable.Now, lighting device (case intraoral illumination) is if 900 roof 740 or the underside walls 780 being configured at forming chamber, then when making to reach sidewall 790 as the 1st wind path accessory 762 of cap assembly, compared with lighting device 900 being located at the situation of sidewall 790 inner face, the 1st wind path accessory 762 without the need to the part by being provided with lighting device 900 excises or arranges opening, therefore the shape as the Appearance Panel (the 1st wind path accessory 762) of cap assembly becomes easy, can obtain the heat insulating box of low cost, refrigerator, equipment.At this, the Appearance Panel as cap assembly can be formed as covering the roof 740 of forming chamber and back face wall 730 at least partially or whole inner face side of wall.

(thickness of polyurethane, the filling rate of Vacuumed insulation panel)

At this, the relation of the filling rate of Vacuumed insulation panel 400 and the intensity of casing is described.Figure 15 is the figure representing the density of hard polyurethane foams and the relation of thermal conductivity, Figure 16 represents the density of hard polyurethane foams and the figure of Deflection Modulus of Elasticity, the figure of Figure 17 to be the figure of the relation of the stream thickness of the polyurethane represented when being filled with hard polyaminoester and the thermal conductivity of polyurethane, Figure 18 be relation of the stream thickness of the polyurethane represented when being filled with hard polyaminoester and the Deflection Modulus of Elasticity of polyurethane.Figure 15 ~ Figure 18 fills hard polyaminoester and experimental result under the model configuration body making it foam between two faces with predetermined gap (stream), the face of the side of stream is the steel plate (such as forming the profile of heat insulating box 700 and the coated steel plate of outer container 710 of Vacuumed insulation panel or refrigerator 1) as the 1st parts, the face of the opposite side of stream is resin (such as, interior case 750 use ABS(acrylonitrile, butadiene, cinnamic copolymerization resin), EPS(foamed plastic as the 2nd parts) etc. resin).

In Figure 15, transverse axis represents the density (kg/m of hard polyurethane foams ³), the longitudinal axis represents the thermal conductivity [W/(mK)] of hard polyurethane foams.In addition, Tu16Zhong, transverse axis represents the density (kg/m of hard polyurethane foams ³), the longitudinal axis represents the Deflection Modulus of Elasticity (MPa) of hard polyurethane foams.In Figure 17, transverse axis represents fills the stream thickness (mm) of hard polyurethane foams, and the longitudinal axis represents the thermal conductivity [W/(mK)] of hard polyurethane foams.In Figure 18, transverse axis represents the stream thickness (mm) of filling hard polyurethane foams, and the longitudinal axis represents the Deflection Modulus of Elasticity (MPa) of hard polyurethane foams.At this, the stream thickness table of filling hard polyurethane foams is shown in stream fills hard polyurethane foams and the thickness of the hard polyurethane foams of the state foamed.

According to Figure 15, Figure 16, hard polyurethane foams thermal conductivity, Deflection Modulus of Elasticity when density is larger is larger, and in density, more hour thermal conductivity, Deflection Modulus of Elasticity are less.That is, density and thermal conductivity or density and Deflection Modulus of Elasticity are proportional relation substantially.

According to Figure 17, Figure 18, hard polyurethane foams thermal conductivity when the stream thickness (or filling hard polyurethane foams and the thickness of the polyurethane of the state foamed in stream) of filled polyurethane is narrower is larger, and in addition, Deflection Modulus of Elasticity is also larger.Therefore, the thickness of the polyurethane in stream after foaming is thicker, and thermal conductivity is less, and heat-proof quality is higher, but Deflection Modulus of Elasticity is less, and intensity is lower.Therefore, when the thickness that reduce polyurethane is with thinning wall thickness, Deflection Modulus of Elasticity increases, therefore no problem in intensity, but thermal conductivity becomes excessive, and heat-proof quality worsens, and the thickness of polyurethane therefore cannot be made to be less than to a certain degree (such as 15mm).

At this, at Figure 17, Tu18Zhong, if the stream thickness of filled polyurethane (or the thickness of polyurethane in stream after foaming) narrows, then density increases, if density increases, then thermal conductivity increases as shown in figure 15, and heat-proof quality worsens.At this, as shown in figure 17, if the stream thickness of filled polyurethane (or the thickness of polyurethane in stream after foaming) becomes predetermined thickness (such as 11mm) below, then thermal conductivity sharply increases, and heat-proof quality worsens.Hard polyurethane foams foams and solidifies under the state bonding to the 1st parts and the 2nd parts between the 1st parts forming polyurethane stream and the 2nd parts, now, polyurethane forms sandwich layer and forms the boundary layer being called cortex in the both sides (the 1st component side and the 2nd component side) of this sandwich layer.

Figure 23 A and Figure 23 B is the schematic diagram of the cross sectional shape after hard polyurethane foams foaming, Figure 23 A is the schematic diagram in the cross section represented when to be filled with hard polyurethane foams 701A between the 1st parts (interior case 750) and the 2nd parts (outer container 710), the schematic diagram in cross section when being filled with hard polyurethane foams 701A when Figure 23 B is and represents and be folded with the 3rd parts (Vacuumed insulation panel 400) between the 1st parts (interior case 750) and the 2nd parts (outer container 710) between the 1st parts and the 3rd parts.

In Figure 23 A, the thermal wall possessing polyurethane foam filled between the 1st parts and the 2nd parts is made up of the 1st parts (such as case 750), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 2nd parts (such as outer container 710) successively.On the other hand, as shown in fig. 23b, time between the 1st parts (interior case 750) and the 2nd parts (outer container 710) as the 3rd parts configuration Vacuumed insulation panel 400, thermal wall is made up of the 1st parts (interior case 750), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 3rd parts (Vacuumed insulation panel 400), the 2nd bonding agent 715, the 2nd parts (outer container 710) successively.In addition, the 1st cortex 701B, sandwich layer 701C and the 2nd cortex 701D form hard polyurethane foams 701A.

Cortex is formed at the 1st nearby components or the 2nd nearby components or the 3rd nearby components, the scope that the stream thickness (thickness of polyurethane) of polyurethane uses for prior art namely about 20mm ~ 30mm time, the thickness of cortex is enough little relative to the thickness of sandwich layer, to density, the impact of thermal conductivity etc. is very little, if but the thickness of polyurethane be predetermined thickness (such as 11mm) below, then cortex thickness relative to sandwich layer thickness shared by ratio become large, to the density of polyurethane, thermal conductivity, the impact of Deflection Modulus of Elasticity sharply increases, density, thermal conductivity, Deflection Modulus of Elasticity sharply becomes large.Therefore, heat-proof quality sharply worsens.In addition, as shown in figure 18, because the density of polyurethane rises, the Deflection Modulus of Elasticity of polyurethane also sharply rises.

Therefore, in prior art, if reduce the thickness of polyurethane, then Deflection Modulus of Elasticity increase, intensity improve, but the thermal conductivity of polyurethane rises, heat-proof quality worsens, and therefore cannot reduce the thickness of polyurethane, and use in the scope of about 15mm ~ 30mm.In prior art, with polyurethane be main thermal insulation barriers, Vacuumed insulation panel is that the mode of auxiliary thermal insulation barriers is configured, therefore in the scope that the heat-proof quality of polyurethane thermal insulation barriers can not worsen, the thickness of polyurethane is determined, even if also ensure that about 15mm ~ 20mm in narrow part.

But, in the present embodiment, thermal wall is formed for main thermal insulation barriers by the mode of intensity that Vacuumed insulation panel obtains casing with Vacuumed insulation panel, therefore the hard polyaminoester being configured with the part of Vacuumed insulation panel does not require heat-proof quality, even if thus be predetermined thickness (such as 11mm, preferred 6mm) also no problem below, thinner then Deflection Modulus of Elasticity rises, casing intensity improves, therefore better.When predetermined thickness is below 11mm, the thickness of cortex becomes large to the impact of sandwich layer, and thermal conductivity sharply increases, and heat-proof quality sharply reduces, and is therefore difficult in prior art make the thickness of hard polyurethane foams be below 11mm.In prior art, about the thickness of hard polyurethane foams, even if local can make predetermined value be below 11mm among a small circle, be also difficult to make average thickness be below 11mm.And then if predetermined thickness is below 6mm, then the impact of thickness on sandwich layer of cortex increases further, and heat-proof quality worsens more, be therefore difficult in prior art use.But in the present embodiment, make Vacuumed insulation panel 400 have the heat-proof quality of heat insulating box 700, though therefore the thickness of thinning polyurethane use also no problem.Therefore, in the present embodiment, by the thickness of hard polyurethane foams is set as below 11mm (being preferably less than 10mm), the Deflection Modulus of Elasticity of hard polyurethane foams can be increased, improve the intensity (rigidity) of casing 700.In addition, if the thickness of hard polyurethane foams is set as below 6mm, can increase the Deflection Modulus of Elasticity of hard polyurethane foams further, therefore the intensity (rigidity) of casing 700 is further enhanced.

In addition, do not configuring the part of Vacuumed insulation panel 400, the thickness of polyurethane can with the thickness of Vacuumed insulation panel (such as about 15mm ~ 30mm) thicker formed, therefore the thickness of polyurethane can guarantee about 20mm ~ 40mm, the scope (below the thickness 11mm of polyurethane) that sharply can not rise in the thermal conductivity of polyurethane uses, can use in the scope (thickness of such as polyurethane is the scope of such as more than 15mm) that the rising degree of the thermal conductivity of polyurethane (slope) is little, even if therefore consider that the uneven thickness of polyurethane also can guarantee that the heat-proof quality of polyurethane is below predetermined value.Therefore, the intensity of heat insulating box 700 and the heat-proof quality both sides of heat insulating box 700 can be met.

At this, at the 1st parts that the face of the side of polyurethane stream uses, use the resins such as resin (such as, interior case 750 use ABS(acrylonitrile, butadiene, cinnamic copolymerization resin) or EPS(foamed plastic)).The face of the opposite side of stream is used as the aluminium-vapour deposition film of the outsourcing material of Vacuumed insulation panel, forms the steel plates such as the coated steel plate (PCM) of outer container 710.

Following explanation be configured with the part of Vacuumed insulation panel 400 (such as recess 440 or the 2nd recess 441 etc.), polyurethane thickness relative to the relation of ratio (thickness/(thickness+Vacuumed insulation panel thickness of polyurethane) of=polyurethane) and composite guide heating rate (thermal conductivity by the thermal wall of Vacuumed insulation panel and polyurethane composition) of thickness (thickness of the thickness+polyurethane of Vacuumed insulation panel) of thermal wall possessing polyurathamc and Vacuumed insulation panel 400.

Figure 19 is that the thickness of polyurethane when representing that wall thickness (between the inwall of wall thickness) is fixed as 27mm is relative to the ratio of the thickness of the thermal insulation barriers by Vacuumed insulation panel and polyurethane composition, the figure with the relation of composite guide heating rate.In Figure 19, transverse axis represents thickness/(thickness+Vacuumed insulation panel thickness of polyurethane) of the thickness of polyurethane relative to the ratio of the thickness of the thermal insulation barriers by Vacuumed insulation panel and polyurethane composition, i.e. polyurethane, and the longitudinal axis represents composite guide heating rate (thermal conductivity by Vacuumed insulation panel and polyurethane composition get up).At this, using the thickness of the thickness+Vacuumed insulation panel of the thickness of polyurethane and the total of the thickness of Vacuumed insulation panel, i.e. polyurethane as thickness in wall.

As shown in Figure 19, relative to thickness in wall, when the thickness of polyurethane is less, composite guide heating rate diminishes, and heat-proof quality improves.At this, composite guide heating rate represents the thermal conductivity of composite component polyurethane and Vacuumed insulation panel combined.In figure, in the thickness/wall of polyurethane, thickness is with 0.3 for boundary's slope changes, and compared with when being greater than 0.3 with thickness in the thickness/wall of polyurethane, in the thickness/wall of polyurethane, thickness is about less than 0.3 time, and slope is less, and the ratio of the reduction of composite guide heating rate is less.Figure is the experimental verification of thickness one timing in wall, and in the thickness/wall of therefore polyurethane, the ratio of thickness is less, and the thickness of polyurethane is less, otherwise the thickness of Vacuumed insulation panel is larger, and therefore the thickness of Vacuumed insulation panel is larger relative to the ratio in wall shared by thickness.That is, relative to thickness in wall, during the less thick of polyurethane, the thickness of Vacuumed insulation panel increases relative to the ratio of the thickness of polyurethane.In figure, in the thickness/wall of polyurethane, thickness is about 0.6 place, the thickness of the Thickness Ratio Vacuumed insulation panel of polyurethane is large, therefore the thermal conductivity of polyurethane is comparatively large on the impact of composite guide heating rate (Vacuumed insulation panel and polyurethane thermal conductivity altogether), and composite guide heating rate is comparatively large (heat-proof quality is poor) also.If thickness in the thickness/wall reducing polyurethane, then the thickness of Vacuumed insulation panel increases relative to the ratio of the thickness of polyurethane, therefore the thermal conductivity of polyurethane is compared, the impact of thermal conductivity on composite guide heating rate of Vacuumed insulation panel is larger, result, along with thickness/(thickness of the thickness+Vacuumed insulation panel of polyurethane) of polyurethane diminishes, the thermal conductivity (composite guide heating rate) of the composite component that polyurethane and Vacuumed insulation panel combine reduces.At this, until when the thickness of polyurethane/(thickness of the thickness+Vacuumed insulation panel of polyurethane) is about 0.3, compare the thermal conductivity of polyurethane, the impact of thermal conductivity on composite guide heating rate of Vacuumed insulation panel is larger, therefore the reduction ratio of composite guide heating rate is also larger, thickness/(thickness of the thickness+Vacuumed insulation panel of polyurethane) of polyurethane is less, and composite guide heating rate is less, and heat-proof quality significantly improves.

But, be less than about in the of 0.3 from the thickness of polyurethane relative to thickness/(thickness of the thickness+Vacuumed insulation panel of polyurethane) of the ratio of thickness in wall, i.e. polyurethane, the slope of the reduction of composite guide heating rate changes, and the slope of the reduction of composite guide heating rate diminishes (ratio of the reduction of composite guide heating rate diminishes).This be considered to due to, the thickness of polyurethane is relative to less thick in the thickness/wall of the ratio of thickness in wall, i.e. polyurethane, thus relative to the heat-proof quality of composite component (parts by polyurethane and Vacuumed insulation panel combine), the heat-proof quality of Vacuumed insulation panel becomes overriding, and the impact of heat-proof quality on the heat-proof quality of composite component of polyurethane diminishes.Therefore, in the present embodiment, in the thermal wall formed by composite component (the polyurethane heat insulating member formed adjacent with Vacuumed insulation panel both sides), with make thickness in the thickness/wall of polyurethane be less than 0.3 mode set the thickness of polyurethane time, the ratio of the reduction of heat-proof quality diminishes, even if therefore the thickness of polyurethane or the thickness of Vacuumed insulation panel produce uneven, the inequality of heat-proof quality also can be made less, therefore preferably.Otherwise, also thickness in the thickness/wall of Vacuumed insulation panel can be set as more than 0.7.

Therefore, when setting the thickness of polyurethane to make mode that in the thickness/wall of polyurethane, thickness is about less than 0.3, can reduce composite guide heating rate, the heat-proof quality of composite component is largely increased.In addition, if consider, the inequality (or inequality of the thickness of Vacuumed insulation panel) of the thickness of polyurethane carries out setting to make thickness in the thickness/wall of polyurethane to be in the scope of less than 0.3, even if then the thickness of polyurethane, the thickness of Vacuumed insulation panel produce uneven, also the reduction of the heat-proof quality of composite component can be suppressed, and the inequality of the composite guide heating rate of composite component can be suppressed, therefore, it is possible to obtain high, the high performance thermal wall of reliability, heat insulating box, refrigerator, equipment etc.

Figure 20 be represent the volume of Vacuumed insulation panel 400 relative to space in wall 315 volume shared by ratio and Vacuumed insulation panel filling rate, with figure to the relation of the deflection of heat insulating box during heat insulating box 700 imposed load (load).In fig. 20, the deflection that transverse axis represents the filling rate of Vacuumed insulation panel, the longitudinal axis represents heat insulating box.At this, the filling rate of Vacuumed insulation panel be Vacuumed insulation panel 400 relative to the space 315 in wall volume shared by the ratio (ratio) of volume, the deflection of heat insulating box is that under the state having door, on the side of distance casing, the height and position of about about 1/4 is along general horizontal direction (laterally in the heat insulating box of such as refrigerator 1 grade, being left and right directions when observing front openings portion in front) upper end position of the sidewall 790 of casing 700 when being applied with predetermined load is in the result of calculation of the deflection of left and right directions (transverse direction), if the deflection when filling rate of Vacuumed insulation panel 400 is 20% is 1.Figure 20 is the covering rate (such as 65%), polyurethane density (the such as 60kg/m that make Vacuumed insulation panel ³), the wall thickness (such as 30mm) etc. that is added of the thickness of the thickness (such as 28mm) of the Deflection Modulus of Elasticity (such as 15MPa) of the Deflection Modulus of Elasticity (such as 9MPa) of polyurethane, Vacuumed insulation panel, composite component, outer container and interior case fixes and makes the varied in thickness of Vacuumed insulation panel to change the result during filling rate of Vacuumed insulation panel.

In fig. 20, the filling rate of Vacuumed insulation panel is larger, and box deformation amount is less.This be considered to due to, the Deflection Modulus of Elasticity of Vacuumed insulation panel is larger than the Deflection Modulus of Elasticity of polyurethane, thus increase relative to the ratio of the polyurethane volume in heat insulating box with the volume of Vacuumed insulation panel, the impact of the Deflection Modulus of Elasticity of Vacuumed insulation panel becomes large, and the rigidity of casing 700 increases.When the filling rate of Vacuumed insulation panel 400 is more than 40%, the reduction ratio of the deflection of casing becomes minimum, even if the filling rate of Vacuumed insulation panel increases, box deformation amount also changes hardly.This is considered to because, Vacuumed insulation panel 400 is basic close to saturated for the influence degree of casing intensity (distortion of casing).

The Deflection Modulus of Elasticity of Vacuumed insulation panel 400 is larger than hard polyurethane foams, therefore by increasing the volume of Vacuumed insulation panel 400 relative to the ratio (ratio) (increasing the filling rate of Vacuumed insulation panel) shared by the volume in space 315, the deflection of heat insulating box 700 can be reduced, therefore, it is possible to improve the heat-proof quality of heat insulating box 700, increase the casing intensity of heat insulating box 700 or refrigerator 1 or equipment.Now, if the thickness increasing Vacuumed insulation panel 400 increases filling rate, while the effect that just can improve in the intensity realizing casing, improve heat-proof quality.At this, the filling rate of Vacuumed insulation panel can be increased by the thickness increasing Vacuumed insulation panel, also can be increased the filling rate of Vacuumed insulation panel relative to the ratio (covering rate of Vacuumed insulation panel) of the surface area of casing 700 by the surface area increasing Vacuumed insulation panel 400, now also can increase the intensity of casing, and, by increasing the covering rate of Vacuumed insulation panel 400, the filling rate of Vacuumed insulation panel can be increased.In addition, if increase the covering rate of Vacuumed insulation panel 400, then the configuration scope (configuration position) of Vacuumed insulation panel increases, can the wall thickness of thinning heat insulating box 700, and storeroom internal volume therefore can be made to increase the amount of wall thickness reduction.

In the present embodiment, such as, formed heat insulating box profile outer container 710 and formed heat insulating box storeroom inwall a part in space 315 between case 750 possess Vacuumed insulation panel 400 at least partially, the filling rate of the Vacuumed insulation panel 400 in space 315 is made to be more than 40%, and make Vacuumed insulation panel 400 be more than 60% relative to the area ratio (covering rate) of the surface area of outer container 710, thus can obtain that heat-proof quality is high, casing intensity also large and heat insulating box, refrigerator, equipment etc. that reliability is high.At this, in the present embodiment, be configured to by the high Vacuumed insulation panel 400 of the hard polyurethane foams that Deflection Modulus of Elasticity is more used than existing heat insulating box to bear the wall intensity of heat insulating box 700, therefore, it is possible to meet casing intensity and heat-proof quality simultaneously, and can thinning wall thickness, therefore storeroom internal volume also can increase.

The heat insulating box 700 of present embodiment, by the filling rate of Vacuumed insulation panel 400 higher than hard polyaminoester for bending strength being set as more than predetermined value (or in preset range) or the filling rate of Vacuumed insulation panel 400 and covering rate both sides being set as more than predetermined value (or in preset range), can meet heat-proof quality and casing intensity and can the wall thickness of thinning heat insulating box 700 simultaneously.Therefore, heat insulating box 700 need not be changed, the appearance and size of refrigerator 1 can expand internal volume in storeroom, collecting article, reserve that the inside that can be increased in heat insulating box 700 or refrigerator 1 or equipment can be stored.In addition, when wall intensity reduces, heat insulating box 700 can be there is and be out of shape, such as, be located at inner shelf 80 offset track portion and fall or the problem such as sliding variation of storeroom (or the door of drawer type or box body or shutter door etc.) of drawer type.But in the present embodiment, owing to the filling rate of Vacuumed insulation panel 400 and/or covering rate to be set as more than predetermined value (in preset range), therefore can the wall thickness of thinning heat insulating box 700, and casing intensity and heat-proof quality can be improved, therefore, it is possible to suppress the generation of following situation: shelf 80 offset track portion and falling, or the sliding of the storeroom of drawer type (or door or box body or shutter door etc.) is deteriorated, and causes reliability to reduce.

In addition, the heat insulating box 700 of present embodiment 1 makes the filling rate of the Vacuumed insulation panel 400 in space 315 be less than 90%.According to the technological thought of above-mentioned present embodiment, it is desirable in space 315 is all Vacuumed insulation panel 400.But, as illustrated at Figure 11 etc., wall 730 is provided with protuberance 450 or jut 910 overleaf, in addition the orbit portion 755 being formed at interior case 750 is made to arrange highlightedly in space 315, when in addition heat insulating box 700 being used for such as refrigerator 1, the pipe 720 of storage wire harness also will be configured in space 315 in wall, therefore be difficult to make the filling rate of Vacuumed insulation panel 400 more than 90%, above-mentioned wire harness is by connecting the compressor 12 carried in the Machine Room 1A of heat insulating box 700, the control device 30(controlling storage in substrate room 31 such as controls the device of the rotating speed of compressor etc.) etc. distribution class boundling.In addition, when heat insulating box 700 is applied to such as refrigerator 1, in space 315, also refrigerant piping 725 etc. to be configured.Therefore, to configure Vacuumed insulation panel 400 more than 90% ground in space 315, just need the Vacuumed insulation panel 400 with the form fit of distribution class 720, refrigerant piping 725, orbit portion 755 etc., the shape of Vacuumed insulation panel 400 becomes complicated, thus Vacuumed insulation panel 400 shaping (or formation) becomes difficulty, therefore the filling rate of Vacuumed insulation panel 400 is set as less than 90%.

In addition, the problem deformed to suppress the intensity of heat insulating box 700 to reduce, need to make outer container 710 and interior case 750 bonding with Vacuumed insulation panel 400 and possess adhesive strength, and interior case 750 be provided with orbit portion 755 for keeping being located at shelf 80 in storeroom (such as refrigerating chamber 2), other accessories (such as lighting device 900 or mist device 200 or partition wall 24 etc.) situation more, complex-shaped.Therefore, even if be easy to by Vacuumed insulation panel 400 by PUR or double faced adhesive tape etc. the 2nd bonding agent bond to outer container 710 side, be also difficult to make Vacuumed insulation panel 400 bond to complex-shaped interior case 750 side and obtain adhesive strength.

But, when hard polyurethane foams is used as the bonding agent between interior case 750 and Vacuumed insulation panel 400, can be made it in space 315 to fill while the flowing of two-phase state, to foam, even if also can interior case 750 and Vacuumed insulation panel 400 be bonded together by polyurethane without problems when therefore there are protuberance 450, jut 910, orbit portion 755, other accessories in space 315.Certainly, also hard polyurethane foams can be filled as bonding agent between outer container 710 and Vacuumed insulation panel 400 or between outer container 710 and interior case 750.Now, if the non-filling part (i.e. space) of hard polyurethane foams is not filled in generation in heat insulating box 700, then the heat-proof quality of heat insulating box 700 can reduce.Therefore, in the heat insulating box 700 of present embodiment, need to ensure the predetermined gap (such as about more than 1mm, preferably about more than 3mm) to a certain degree of filling needed for hard polyurethane foams, the filling rate of the Vacuumed insulation panel 400 therefore in space 315 can be less than 90%, is preferably less than 80%.

But if make the filling rate of the Vacuumed insulation panel 400 in space 315 increase, then the filling rate of the hard polyurethane foams in space 315 will reduce.Therefore, the thickness of the polyurethane between outer container 710 and interior case 750 reduces, and the casing intensity of heat insulating box 700 may be caused to reduce.But the heat insulating box of present embodiment 700, by using heat-proof quality, Vacuumed insulation panel 400 that bending rigidity is all good than polyurethane, can suppress the reduction of casing intensity.In addition, in the present embodiment, technological thought is mainly bear heat insulating function and intensity by the Vacuumed insulation panel 400 that thermal conductivity is little, therefore as shown in figure 20, by making the filling rate of Vacuumed insulation panel be more than 40%, even if the loading of hard polyaminoester reduces, the intensity of casing 700 also can be improved.In addition, as shown in figure 19, by thickening the thickness (namely increasing the filling rate of Vacuumed insulation panel) of Vacuumed insulation panel 400, can reduce the composite guide heating rate of compound heat-insulation part Vacuumed insulation panel and hard polyurethane foams combined, therefore the heat-proof quality of casing 700 also improves.

At this, if the density increasing hard polyurethane foams increases Deflection Modulus of Elasticity (bending rigidity), then the heat-proof quality of hard polyurethane foams self can reduce, but by making the covering rate of Vacuumed insulation panel 400 and filling rate be more than predetermined value, the impact of the reduction of the heat-proof quality of polyurethane can diminish and not become problem.In the heat insulating box 700 of present embodiment, as shown in figure 16, by make the density ratio prior art of hard polyurethane foams large, be such as greater than 60kg/m ³the Deflection Modulus of Elasticity of hard polyurethane foams can be made for large more than the 15MPa of the Deflection Modulus of Elasticity (such as about 6 ~ 10MPa) of the hard polyurethane foams used than existing heat insulating box, the casing intensity of the part not configuring Vacuumed insulation panel 400 can also be improved.Therefore, the equipment such as heat insulating box 700, refrigerator 1, showcase, hot water supply device of present embodiment, being more than 40% by making the filling rate of Vacuumed insulation panel 400, making the laterodorsal covering rate of Vacuumed insulation panel be more than 70%, the intensity that the reduction because of the filling rate of hard polyurethane foams can be suppressed to cause reduces, and heat insulating box 700 can also be suppressed to be out of shape because of cause crooked of the weight that cannot tolerate collecting article.Namely, by increasing the filling rate of Vacuumed insulation panel 400, the intensity of heat insulating box 700 can be improved, in addition, excellent heat-proof quality can be obtained, therefore, it is possible to obtain the high and energy-conservation heat insulating box possessing Vacuumed insulation panel of reliability, possess the refrigerator of Vacuumed insulation panel, possess the showcase of Vacuumed insulation panel, possess the hot-water supply of Vacuumed insulation panel, possess the equipment etc. of Vacuumed insulation panel.

In addition, the density adjustment of hard polyurethane foams, such as, can fill more than prior art by the amount of the stoste making the hard polyurethane foams be injected in space 315 (lengthen injection length or strengthen injection pressure) and adjust larger by density or less.In addition, the Deflection Modulus of Elasticity of hard polyurethane foams increases substantially pro rata with the size of density as shown in figure 16, therefore increase density and just can increase Deflection Modulus of Elasticity, and Deflection Modulus of Elasticity larger time, gear housing rigidity increases, therefore preferred, but the Deflection Modulus of Elasticity of polyurethane is preferably below 150MPa.If the Deflection Modulus of Elasticity of hard polyurethane foams is greater than 150MPa, then the density of hard polyurethane foams becomes excessive, can cannot be foamed into spongy and solidify, heat-proof quality sharply reduces, therefore can suppress the reduction of heat-proof quality when the Deflection Modulus of Elasticity of hard polyurethane foams is below 150MPa thus preferably, high performance heat insulating box can be obtained.

In the present embodiment, heat insulating box 700 is such as applied to the refrigerator of following specification.

(1) the total thickness of slab of outer container 710 and interior case 750 is used to be about below 2mm, to comprise the heat insulating box (at this, the average distance (in wall thickness) eliminating the wall thickness direction in the space 315 of the thickness of slab of outer container 710 and interior case 750 is about 18mm ~ about 38mm) that the average wall thickness of the heat insulating box 700 of the thickness of slab of outer container 710 and interior case 750 thickness of slab is about more than 20mm about below 40mm.

(2) thickness of Vacuumed insulation panel 400 is about 10mm ~ about 30mm, and the mean flowpath width (polyurethane stream thickness) being configured with the wall thickness direction of the hard polyurethane foams in the space 315 in the wall of the part (such as recess 440 or the 2nd recess 441) of Vacuumed insulation panel is more than 1mm (preferred more than 3mm), below 11mm (preferred below 6mm).

(3) thermal conductivity of hard polyurethane foams is 0.018W/(mK) ~ 0.026W/(mK).

(4) thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/(mK) ~ 0.0025W/(mK).

(5) internal volume is the power consumption under 200L ~ 600L level, predetermined condition is about below 60W degree.

The heat-proof quality of this refrigerator 1 is by being set to the filling rate that makes Vacuumed insulation panel 400 and covering rate and being in predetermined scope and selecting size, the thickness of Vacuumed insulation panel 400, Vacuumed insulation panel 400 is made to become overriding relative to the heat-proof quality of heat insulating box, the casing intensity of heat insulating box, thus the thermal conductivity of Vacuumed insulation panel 400 less time, the composite guide heating rate of heat insulating box can be reduced thus preferably, be preferably 0.0030W/(mK) below.If the thermal conductivity of Vacuumed insulation panel 400 is more than 0.0030W/mK, then wall thickness reduces and becomes large to the impact of heat-proof quality, and heat-proof quality worsens, and power consumption amount increases.Therefore, in the present embodiment, be 0.0030W/(mK by making the thermal conductivity of Vacuumed insulation panel 400) below, the impact that the heat-proof quality relative with thinning wall thickness reduces can be suppressed.In addition, the thermal conductivity of Vacuumed insulation panel 400 is the smaller the better, but in order to thermal conductivity is reduced 0.001W/(mK) spent by cost significantly increase, the thermal conductivity therefore using Vacuumed insulation panel 400 is 0.0012W/(mK) more than parts.If the thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/(mK) above 0.0025W/(mK) below, just little than the thermal conductivity of hard polyurethane foams about 10 times, therefore the heat-proof quality of heat insulating box 700 is especially good compared to existing technology, can meet product specification.Therefore, Vacuumed insulation panel 400 uses thermal conductivity for about 0.0012W/(mK) above 0.0030W/(mK) (be preferably about 0.0019W/(mK) above 0.0025W/(mK below) below) parts.

As an example of the heat insulating box 700 of embodiments of the present invention, the relation of the box deformation amount of the Deflection Modulus of Elasticity of the filling rate of wall thickness and Vacuumed insulation panel 400, hard polyurethane foams, heat insulating box 700 is shown in Table 1.The item 1 of table 1 is existing specification, the result when Deflection Modulus of Elasticity of the polyurethane of be wall thickness be 40mm, the filling rate of Vacuumed insulation panel 400 is 20%, filling between interior case 750 and Vacuumed insulation panel 400 is 9MPa.At this, the Deflection Modulus of Elasticity of Vacuumed insulation panel 400 uses the parts of 20MPa.According to item 1 and the item 2 of table 1, when the filling rate of Vacuumed insulation panel 400 is 20%, the Deflection Modulus of Elasticity of polyurethane is 9MPa, if make the wall thickness of heat insulating box 700 be thinned to 30mm from 40mm, then casing intensity reduces.Therefore, known as shown in item 3, when making wall thickness reduction to 30mm, if make the filling rate of Vacuumed insulation panel 400 increase to more than 40%, although then box deformation amount is than item 1(prior art) slightly large, be reduced to and item 1(prior art) equal degree.

As shown in the item 4 of table 1, even if by the item 1 of the wall thickness of heat insulating box 700 from existing 40mm(table 1) be thinned to 30mm, as long as make the filling rate of Vacuumed insulation panel 400 be more than 40% and the Deflection Modulus of Elasticity of polyurethane is more than 15Mpa (item 4 of table 1), box deformation amount just can be made less than prior art (item 1), the casing intensity of heat insulating box 700 therefore can be made to be more than existing parts (item 1).That is, even if reduce wall thickness (such as reducing to 30mm from 40mm), as long as the filling rate of Vacuumed insulation panel 400 and the Deflection Modulus of Elasticity of polyurethane are set as more than predetermined value, heat-proof quality is improved with just can not reducing casing intensity.Therefore, in the present embodiment, by using the parts of more than Deflection Modulus of Elasticity 20MPa as Vacuumed insulation panel 400, and the filling rate of Vacuumed insulation panel 400 is set as more than 40%, the Deflection Modulus of Elasticity of hard polyurethane foams is set as more than 15MPa, even if the wall thickness of thinning heat insulating box (being such as thinned to 30mm from 40mm), the intensity of heat insulating box 700 also can be improved compared to existing technology.

In addition, form the outsourcing material (exterior film) of the profile of Vacuumed insulation panel 400, compare aluminium foil film and preferably use aluminium-vapour deposition film.In order to the heat leak (heat is rearwardly conducted and the so-called heat bridge leaked from the surface of Vacuumed insulation panel 400 via the outsourcing material of Vacuumed insulation panel 400) that the outsourcing material suppressed along Vacuumed insulation panel 400 occurs, as the outsourcing material of Vacuumed insulation panel 400, compare aluminium foil film, preferably the aluminium-vapour deposition film being difficult to produce heat bridge is used as outsourcing material (exterior film).

In addition, the mensuration of the Deflection Modulus of Elasticity of the hard polyurethane foams in present embodiment 1, thermal conductivity, density, such as, hard polyurethane foams by cutting pre-sizing (such as 100 × 100 × more than 5mm) measures.Be configured with the part of Vacuumed insulation panel 400, from left and right side, the back side, end face, part that each face in these five faces, bottom surface is configured with Vacuumed insulation panel cut multiple, calculates its mean value.(when only cutting 1 position, carry out many places mensuration etc. at 1 position and carry out substitute and be advisable).When door is also configured with Vacuumed insulation panel, opposite house also measures density, Deflection Modulus of Elasticity, the thermal conductivity of polyurethane.In addition, do not configuring the part of Vacuumed insulation panel 400, cutting multiple to each face in left and right side, the back side, end face, these five faces, bottom surface yet, and calculate its mean value.In the present embodiment, be all from inferring that density or the larger place of Deflection Modulus of Elasticity carry out cutting and measuring in any case.In addition, when hard polyurethane foams can not be cut into pre-sizing when there is the distribution accessory 720 etc. of refrigerant piping 725, lead-in wire etc. etc., is advisable as the position of the hard polyurethane foams that can cut pre-sizing in the position close to center.

In the present embodiment, to each of these six faces of left surface, right flank, the back side, end face, bottom surface or door, measure density or the Deflection Modulus of Elasticity of the polyurethane of the part being configured with Vacuumed insulation panel 400 and the part do not configured, make the density of polyurethane or Deflection Modulus of Elasticity be more than predetermined value.By adjustment the free foaming density of polyurethane, the thickness, wall thickness etc. of Vacuumed insulation panel, the density of the polyurethane of sandwiched between Vacuumed insulation panel 400 and interior case 750 or between Vacuumed insulation panel 400 and outer container 710 or between outer container 710 and interior case 750 or Deflection Modulus of Elasticity can be set as more than predetermined value.

At this, in the present embodiment, in left and right side, the back side, end face, bottom surface or these six faces of door, the density, the Deflection Modulus of Elasticity that each are configured with to the polyurethane of the part of Vacuumed insulation panel 400 to major general are set as more than predetermined value, and the density, the Deflection Modulus of Elasticity that also each can not configured to the polyurethane of the part of Vacuumed insulation panel 400 in addition to major general are set as more than predetermined value.At this, in left and right side, the back side, end face, bottom surface or these six faces of door, make polyurethane density, Deflection Modulus of Elasticity be more than predetermined value if be set to for each face, then also improve at the partial intensities not configuring Vacuumed insulation panel 400.In addition, due to can intensity be obtained in each independent face, therefore only the section sets of needs can be become high strength, can low cost be obtained and high heat insulating box, refrigerator, the equipment of reliability.In addition, be set to and make the density in these six faces of left and right side, the back side, end face, bottom surface or door or the mean value of Deflection Modulus of Elasticity be more than predetermined value (density 60kg/m ³above, more than Deflection Modulus of Elasticity 15MPa) time, can guarantee the intensity of whole casing, therefore, it is possible to obtain, heat-proof quality is high, heat insulating box, refrigerator, equipment that reliability is high.

In addition, for covering rate, the filling rate of Vacuumed insulation panel 400, also be set in these six faces of left and right side, the back side, end face, bottom surface or door make each or multiple face covering rate altogether, filling rate is more than predetermined value, due to intensity, heat-proof quality can be obtained in each independent face, therefore only the section sets of needs can be become high strength, low cost, height is heat insulation, reliability is high heat insulating box, refrigerator, equipment can be obtained.In addition, be set to make this six faces entirety of left and right side, the back side, end face, bottom surface or door for more than predetermined value time, the intensity of whole casing can be guaranteed, improve the heat-proof quality of whole casing, therefore, it is possible to obtain heat insulating box, refrigerator, the equipment that heat-proof quality is high, reliability is high.

Above, in the heat insulating box 700 of present embodiment, the covering rate of Vacuumed insulation panel 400 is made to be greater than predetermined value (60%) (making the laterodorsal covering rate of Vacuumed insulation panel 400 be more than 70%).In addition, the filling rate of Vacuumed insulation panel 400 is made also to be that more than predetermined value (40%) is to reduce the loading of hard polyurethane foams, therefore, it is possible to guarantee heat-proof quality and the casing intensity of heat insulating box, the thin of the wall ratio prior art of heat insulating box 700 can be made simultaneously.Therefore, heat-proof quality is improved thus energy-conservation, and the internal volume in storeroom can be made compared to existing technology to increase the amount of wall thickness reduction, thus can provide heat insulating box 700, refrigerator 1, showcase, the equipment of internal volume good efficiency.Namely, according to the embodiment of the present invention, the appearance and size not changing heat insulating box 700 or the equipment such as refrigerator 1 or showcase increases internal volume (such as the internal volume of storeroom 2 ~ 6) with regard to comparability prior art, the collecting article that the inside that therefore comparability prior art increases heat insulating box 700 or refrigerator 1 can be stored.Thereby, it is possible to obtain easy to use, the energy-conservation equipment such as heat insulating box 700, refrigerator 1, showcase of user.Otherwise, if make internal volume (such as the internal volume of storeroom 2 ~ 6) equal with prior art, then can reduce appearance and size, therefore, it is possible to obtain the equipment such as energy-conservation and compact heat insulating box 700, refrigerator 1, showcase, hot-water supply.

In addition, the heat insulating box 700 shown in present embodiment, the mode of refrigerator 1, shape be an example only.Such as, also the reserve accommodation space of heat insulating box 700 can be formed four accommodation spaces (storeroom) by 3 cross septation plate zonings at above-below direction.In addition, such as also by the reserve accommodation space of heat insulating box 700 by 3 cross septation plate zonings and further by vertical demarcation strip zoning, thus five accommodation spaces (storeroom) can be formed.By increasing the quantity of demarcation strip 24, the intensity of heat insulating box 700 can be improved further.Namely, increase the quantity of demarcation strip 24 to increase the quantity of receiving room, storeroom, can obtain the effect being improved casing intensity by demarcation strip, even if thus the average thickness of the hard polyurethane foams of the thinning part covered by Vacuumed insulation panel 400 (space 315 between Vacuumed insulation panel 400 and interior case 750) (such as below 11mm, be preferably less than 10mm, be more preferably below 6mm), also can guarantee enough casing intensity.Therefore, the appearance and size not changing heat insulating box 700 just can increase the internal volume of storeroom, the collecting article that the inside can increasing heat insulating box 700 further can be stored further.

In addition, in the present embodiment, about the internal structure of demarcation strip 24, can be the formation same with heat insulating box 700.Namely, configure Vacuumed insulation panel 400 in the inner space of demarcation strip 24 and fill hard polyurethane foams, as long as but hard polyurethane foams is used as bonding agent, therefore can be thinner, and can be such as about below 11mm, be preferably less than 10mm, be more preferably about below 6mm.At this, more in the situation not configuring pipe arrangement 725, distribution 720 etc. in demarcation strip 24 as heat insulating box 700, therefore in this case, although also Vacuumed insulation panel 400 can be set as with heat insulating box 700 equal less than more than 40% 90% relative to the filling rate of demarcation strip 24, but about partition wall 24, at roughly whole configuration Vacuumed insulation panel 400 of the size of demarcation strip 24 (space in demarcation strip 24), therefore the filling rate of Vacuumed insulation panel 400 can be brought up to less than about more than 40% 95%.In addition, the Deflection Modulus of Elasticity of hard polyurethane foams is more than 15MPa, density is greater than 60kg/m ³be advisable.By also configuring Vacuumed insulation panel 400 like this in demarcation strip 24 and filling rate being set in preset range, the heat-proof quality of heat insulating box 700 can be improved further.

In the present embodiment, when possessing heat insulating box or the thermal wall of Vacuumed insulation panel, consider assembleability and Vacuumed insulation panel 400 is directly pasted outer container 710 by the 2nd bonding agent that PUR or double faced adhesive tape etc. are different from polyurathamc, hard polyurethane foams is filled as the bonding agent with bonding being main purpose between Vacuumed insulation panel 400 and interior case 750, but also can configure spacer formed by resins such as EPS etc. and Vacuumed insulation panel 400 is floated between interior case 750 and outer container 710 in the space 315 be formed between outer container 710 and interior case 750 and be configured, and hard polyurethane foams is filled between Vacuumed insulation panel 400 and outer container 710 and between Vacuumed insulation panel 400 and interior case 750.In addition, also can by Vacuumed insulation panel 400 by PUR or double faced adhesive tape etc. the 2nd bonding agent directly paste interior case 750 and between Vacuumed insulation panel 400 and outer container 710 filled polyurethane foam.

At this, make Vacuumed insulation panel 400 by spacer etc. float over be configured between outer container 710 and interior case 750 time, spacer can be set in the inner face side of outer container 710 (space between outer container 710 and Vacuumed insulation panel 400) and at spacer spatial placement refrigerant piping 725(such as condensation pipe arrangement).Refrigerant piping 725 is also the condensation pipe arrangement of the flow of refrigerant making the HTHP of discharging from the compressor 12 be configured in the 1A of Machine Room, via the tube wall of refrigerant piping 725 and outer container 710 under the effect of heat conduction etc., make the cold-producing medium of flowing in pipe arrangement 725 be cooled by the ambient air of pipe arrangement 725 and make condensation of refrigerant, thus use as condensation pipe arrangement.In addition, the heat insulating box 700 of present embodiment arranges the resinous spacer of the thickness of more than the diameter with refrigerant piping 725 at the inwall of the outer container 710 with the nonoverlapping position of refrigerant piping 725 (not position) in opposite directions, and make Vacuumed insulation panel 400 paste spacer, so, after making refrigerant piping 725 against the configuration of outer container 710 ground, the spacer being pasted with Vacuumed insulation panel 400 directly can be pasted outer container 710 with double faced adhesive tape etc. in the mode covering refrigerant piping 725, be easy to manufacture.The heat insulating box 700 of present embodiment Vacuumed insulation panel 400 is configured to interior case 750 at predetermined spaced intervals, and Vacuumed insulation panel 400 is configured to outer container 710 at predetermined spaced intervals, therefore become Vacuumed insulation panel 400 and be embedded in formation in hard polyurethane foams, heat-proof quality is improved.

As mentioned above, in the present embodiment, heat insulating box 700 can be foam filled to make Vacuumed insulation panel 400 be embedded in hard polyurethane foams in the space 315 between outer container 710 and interior case 750, the situation that there is condensation pipe arrangement 725 in this situation between outer container 710 and Vacuumed insulation panel 400 is more, but by being configured to utilize the resinous spacers etc. such as EPS to make Vacuumed insulation panel 400 and outer container 710 have predetermined distance, Vacuumed insulation panel 400 can be configured.

In addition, Vacuumed insulation panel 400 is when becoming high temperature, and easy absorption gas around, can cause inner vacuum reduction, thermal conductivity deterioration.When the outer temperature degree such as summer are high, the environment temperature (ambient air temperature) of outer container 710 uprises, the temperature of outer container 710 self also may uprise, in addition, the pipe arrangement 725 used as condensation pipe arrangement also becomes high temperature, therefore from the angle of reliability guaranteeing Vacuumed insulation panel 400, preferably make Vacuumed insulation panel 400 away from outer container 710, refrigerant piping (condensation pipe arrangement) 725.By making Vacuumed insulation panel 400 away from outer container 710, refrigerant piping (condensation pipe arrangement) 725, the deterioration that Vacuumed insulation panel 400 causes because temperature rises can be suppressed, if therefore make Vacuumed insulation panel 400 float with away from the wall of outer container 710 or refrigerant piping 725 by spacer etc., just can suppress the reduction of heat-proof quality, the heat insulating box 700 that can reliability be provided for a long time high, refrigerator 1.

In addition, Vacuumed insulation panel 400 causes inner vacuum to decline sometimes because absorbing gas (air etc.) around, thermal conductivity worsens, but in hard polyurethane foams, bury Vacuumed insulation panel 400 underground by being configured to that the resinous spacers such as EPS are pasted the ground such as outer container 710, the amount of the gas (air etc.) of the surrounding of Vacuumed insulation panel 400 can be reduced, therefore Vacuumed insulation panel 400 can be suppressed to absorb gas (air etc.) around, the deterioration of the Vacuumed insulation panel 400 caused because of the reduction of vacuum can be suppressed, can long term maintenance high heat-proof quality, and the heat insulating box 700 that reliability is high can be provided, refrigerator 1, equipment etc.

Especially, in the heat insulating box 700 of present embodiment, the hard polyurethane foams that hard polyurethane foams uses density ratio existing heat insulating box to use high (density is greater than 60kg/m ³), the bubble therefore in hard polyurethane foams correspondingly can reduce the amount that density increases, and can reduce the amount (air capacity) of the gas in bubble.Therefore, when the mode buried underground by hard polyurethane foams to make the surrounding of Vacuumed insulation panel 400 or cover carries out filling or configuring, the amount of the gas (air etc.) of the surrounding of Vacuumed insulation panel 400 can be reduced, therefore (density of polyurethane is larger can to suppress the reduction of the vacuum of Vacuumed insulation panel 400, space number in polyurethane is fewer, and the air capacity in polyurethane is fewer).Especially when the thinner thickness of polyurethane (when being such as below 11mm), Vacuumed insulation panel 400 easily makes to enter from gases such as the air waited around polyurethane, and the density therefore increasing polyurethane is larger for the effect of the degradation inhibiting of Vacuumed insulation panel 400 to the gas flow reducing the surrounding of Vacuumed insulation panel 400.Therefore, the deterioration of Vacuumed insulation panel 400 can be suppressed further, the heat insulating box 700 that can reliability be provided for a long time high, refrigerator 1, equipment.

In addition, in the present embodiment so that by condensation pipe arrangement 725, the heat insulating box 700 be configured in space 315 is illustrated, but condensation pipe arrangement 725 not being configured in the heat insulating box 700 in space 315 and can certainly burying Vacuumed insulation panel 400 underground in hard polyurethane foams.The amount of the gas of the surrounding of Vacuumed insulation panel 400 can be reduced, therefore can suppress the deterioration of Vacuumed insulation panel 400, the heat insulating box 700 that can reliability be provided for a long time high.

At this, when interior case 750 does not form the heat insulating box 700 of formation, the situation of refrigerator 1 etc. of orbit portion (track of the drawer of drawer type storeroom or recess etc.) 755, interior case 750 for being easy to utilize bonding agent or double faced adhesive tape etc. directly to paste the shape of Vacuumed insulation panel 400, also all or part of of Vacuumed insulation panel 400 can be configured at interior case 750 side.

At this, as shown in the embodiment when Vacuumed insulation panel 400 is directly pasted by PUR or double faced adhesive tape etc. interior case 750 side formation heat insulating box 700, can provide energy-conservation with the Vacuumed insulation panel 400 of less amount and the internal volume efficiency of storeroom heat insulating box 700, the refrigerator 1 better than prior art.Namely, when roughly rectangular-shaped or cylindric heat insulating box 700, in the surface area ratio of outer container 710, the surface area of case 750 is large, therefore when pasting Vacuumed insulation panel 400, the Vacuumed insulation panel 400 of Vacuumed insulation panel 400 specific viscosity being bonded at interior case 750 surface on outer container 710 surface is few, therefore, it is possible to obtain low cost and good heat insulating box, refrigerator, showcase, hot water supply device, the equipment of heat-proof quality.In addition, such as when pasting the Vacuumed insulation panel 400 of formed objects, in the bight of rectangular-shaped heat insulating box 700 (such as the bight of the back side of heat insulating box 700 and the connecting portion of side, or the bight of end face and side, or the bight etc. at end face and the back side), gap (gap between the Vacuumed insulation panel 400 of such as end face and the Vacuumed insulation panel 400 of adjacent side or distance) between the Vacuumed insulation panel 400 of the wall that bight place is adjacent one another are, when Vacuumed insulation panel 400 is configured at outer container 710 side, than large when Vacuumed insulation panel 400 being configured at interior case 750 side.Namely, by Vacuumed insulation panel 400 is configured at interior case 750, compared with when the Vacuumed insulation panel 400 of formed objects being configured at outer container 710, the gap formed each other at adjacent Vacuumed insulation panel 400 can be reduced, make the heat waste caused because of heat leak correspondingly reduce the amount of gap shrinks, heat insulating box 700, refrigerator 1, hot water supply device, showcase, equipment that heat-insulating efficiency is good can be provided.

In addition, the heat insulating box 700 of present embodiment possesses for carrying out the radial type of opening and closing or the shutter door of drawer type to the opening portion of the multiple storerooms 2,3,4,5,6 formed in zonings such as inner utilization partition walls 24.This possesses the profile parts (outside plate) be made up of such as metal and the inner part (inner panel) be made up of such as resin.Further, be formed in the door inner space between profile parts and inner part configure (filling) have hard polyurethane foams and Vacuumed insulation panel 400.Door is also formed based on the following technological thought illustrated by present embodiment: Vacuumed insulation panel is set in preset range relative to the filling rate of heat insulating box and is had the overwhelming majority of heat insulating function by Vacuumed insulation panel 400.Make that the filling rate of the Vacuumed insulation panel 400 of an inner space is 40% ~ 90%, covering rate is more than 70%.

When manufacturing this shutter door, by Vacuumed insulation panel 400 in advance by profile parts that is adhesively fixed such as the 2nd bonding agents, the raw material of liquid hard polyurethane foams is injected the space between Vacuumed insulation panel and inner part, the space between outside parts and inner part, foam in the mode enabling profile parts, Vacuumed insulation panel 400, inner part be integrally formed, thus the hard polyurethane foams as foaming heat insulation part can be filled in door inner space.Now, as long as the thickness of hard polyurethane foams is also have the intensity as bonding agent, can be preferred more than the 3mm of more than 1mm and below 11mm (being preferably less than 10mm, more preferably below 6mm).

In addition, for shutter door, exist, at storeroom 2,3,4,5,6, situation for the framework or door storage portion or shelf 80 etc. supporting containing box (storage box body 520) is installed, thus exist and need the fixed part of the hold-down screw of framework, door storage portion, the installing component etc. of shelf 80 to utilize the secure components such as screw, fixed part, holding member and fastening or remain to the situation of inner side (inside case) of shutter door.In this case, there is the situation that secure component, fixed part, holding member are outstanding to door inner space, if contact with Vacuumed insulation panel 400, just may damage the outsourcing material of Vacuumed insulation panel, therefore preferred in the inner side of shutter door with can not damage Vacuumed insulation panel 400 thickness configuration or filled polyurethane foam.But, when not needing to be installed on installation fitting (such as secure component, fixed part, the holding member etc.) of (inboard side) inside the storeroom of shutter door especially, also Vacuumed insulation panel 400 can be pasted inner panel.In addition, avoid installation fitting when Vacuumed insulation panel is set, also Vacuumed insulation panel can be pasted inner panel.

In addition, when having profile parts (outside plate) and inner part (inner panel), being formed at the configuration of the door inner space between profile parts and inner part Vacuumed insulation panel 400, at profile parts or when filling as foaming heat insulation part hard polyurethane foams between inner part and Vacuumed insulation panel 400, if make the density of foaming heat insulation part be greater than 60kg/m ³maintenance intensity or the constant intensity of the fixed part be then fixed the framework for supporting containing box (storage box body 520) and screw etc. are improved, even if therefore receive weight at box body 520, door is also difficult to distortion, stably can carry out the discrepancy of box body 520, the high refrigerator of reliability, equipment can be obtained.In addition, be improved for the maintenance intensity of the fixed part and screw etc. of the miscellaneous parts such as fixed handle or constant intensity, therefore when the door installing components such as the handle as miscellaneous part to be installed on, door installing component is improved to the installation strength of door, therefore door is difficult to distortion, stably can carry out the opening and closing of door, the high refrigerator of reliability, equipment can be obtained.In addition, if at profile parts or make the hard polyurethane foams as foaming heat insulation part be greater than 60kg/m between inner part and Vacuumed insulation panel 400 ³, then the Deflection Modulus of Elasticity of foaming heat insulation part is improved, and the intensity of door is also improved.

At this, Vacuumed insulation panel 400 can be configured at all shutter door or a part of shutter door.Such as, when the temperature difference of gas and heat insulating box 700 interior (such as in storeroom) is smaller outside (such as the storeroom of the refrigerated storage temperature band such as refrigerating chamber 2, vegetable compartment 5), even if Vacuumed insulation panel 400 is configured at shutter door, the effect that heat-proof quality is improved is also less.In this case, even if Vacuumed insulation panel 400 is not configured to shutter door also can guarantee sufficient heat-proof quality.Vacuumed insulation panel 400 is when the temperature difference of (such as in storeroom) is larger in gas and heat insulating box 700 outside the storeroom of cryogenic temperature band (such as ice-making compartment 3, switch room 4, the refrigerating chamber 6 etc.), if Vacuumed insulation panel 400 is configured at shutter door, then the effect of heat-proof quality improvement is larger.Therefore, outside in gas and heat insulating box 700 when the storeroom of the cryogenic temperature band that the temperature difference of (such as in storeroom) is larger, by Vacuumed insulation panel 400 is configured at shutter door, sufficient heat-proof quality can be guaranteed.

Above, in the heat insulating box 700 of present embodiment or refrigerator 1 or equipment, relative to the space 315 that will be formed between outer container 710 and interior case 750 and Ji Men inner space, the inner space spatial volume altogether of shutter door, the filling rate of the volume ratio shared by Vacuumed insulation panel 400 and Vacuumed insulation panel 400 is in predetermined scope (such as less than more than 40% 80%).Therefore, the wall thickness of heat insulating box 700 (distance such as between outer container 710 and interior case 750 and the thickness of shutter door) can be made thinner than prior art, therefore, it is possible to provide energy-conservation and heat insulating box 700, refrigerator 1, the equipment of internal volume excellent in efficiency in storeroom.Therefore, even if do not change the appearance and size of heat insulating box 700 or refrigerator 1, the interior volume specific ratio in storeroom also can be made greatly existing, the collecting article that the inside therefore can increasing heat insulating box 700 compared to existing technology can be received.Therefore, can provide more energy-conservation than prior art and heat-proof quality good, commodity value is high heat insulating box 700, refrigerator 1, hot water supply device, showcase, equipment.

In addition, by increasing the filling rate of the Vacuumed insulation panel 400 in space 315, the filling rate of the hard polyurethane foams in space 315 reduces.In the heat insulating box 700 of present embodiment, the density ratio prior art of hard polyurethane foams is made (to be such as greater than 60kg/m greatly ³), make the Deflection Modulus of Elasticity of hard polyurethane foams for large more than the 15.0MPa of the Deflection Modulus of Elasticity (about 6MPa ~ 10MPa) of the hard polyurethane foams used than existing heat insulating box.Therefore, the intensity that the heat insulating box 700 of present embodiment can also suppress the reduction because of the filling rate of hard polyurethane foams to cause reduces, there is not heat insulating box 700 because of cause crooked of the weight that cannot tolerate because of the collecting article in reserve accommodation space or storeroom or shutter door and problems such as distortion, the high heat insulating box of reliability 700, refrigerator 1, equipment can be obtained.

Therefore, present embodiment refrigerator 1 or possess band Vacuumed insulation panel 400 heat insulating box 700 equipment in, heat insulating box 700 can being suppressed crooked and make the shutter door such as shutter door inclination cannot the situation of smooth and easy opening and closing, in addition, the deterioration because being out of shape the outward appearance caused can being suppressed.In addition, shutter door can be prevented and produce gap for the position relationship of the contact surface (sealing surface) of the sealing gasket of the opening portion that seals heat insulating box departs from thus make the situation that the air in storeroom (being cold air when refrigerator) flows out outside heat insulating box.Thus, even if the performance of heat insulating box 700 reduces, reliability reduces to use Vacuumed insulation panel 400 also can suppress a large amount of, there is excellent heat-proof quality, therefore can obtain the energy-conservation and refrigerator that reliability is high or there is the heat insulating box of Vacuumed insulation panel or possess the equipment of Vacuumed insulation panel, possess the equipment of heat insulating box.

At this, during the elongated rectangular shape as large in the length for during refrigerator being the height over width direction of above-below direction of heat insulating box 700, compare the partition wall 24 etc. between the bottom surface sections 780 of approximate horizontal configuration, top 740, storeroom, the sidewall 790 configured roughly vertically, back face wall 730 are in elongated shape, and therefore rigidity is weak and be easily out of shape.Therefore, by being set in preset range by the filling rate of Vacuumed insulation panel 400, covering rate as in this embodiment, the intensity (rigidity) of heat insulating box 700 can be improved.In addition, by arranging protuberance 450 or jut 910 also can improve casing intensity.In addition, be arranged to make one end of protuberance 450 overlapping with predetermined length X with the Vacuumed insulation panel 400 being configured at recess 440 or the 2nd recess 441, and the other end is connected to side surface part 790, thus Vacuumed insulation panel 400 can be made to be integrally formed via hard polyurethane foams and protuberance 450, in addition, Vacuumed insulation panel 400 can be made to be integrally formed via hard polyurethane foams and sidewall 790, therefore can to improve the intensity of casing 700.

Figure 21 represents that Vacuumed insulation panel 400 is relative to the figure of the area ratio (back side, side covering rate) shared by the side surface part 790 of heat insulating box 700 and the surface area of back part with the relation of box deformation amount, is result of calculation.About the intensity of heat insulating box, the shape of sidewall 790, back face wall 730 is elongated oblong-shaped, more weak with the roughly square shape phase specific rigidity of top wall 740, underside wall 780, partition wall 24 etc., therefore by the back side, the side covering rate of Vacuumed insulation panel 400 is set as more than predetermined value, casing intensity can be improved.At this, to Vacuumed insulation panel 400 relative to sidewall 790 and back face wall 730 surface area shared by area ratio (back side, side covering rate) be described with the relation of casing intensity.

In figure 21, transverse axis represents that Vacuumed insulation panel 400 is relative to the area ratio (back side, side covering rate) shared by the sidewall 790 of heat insulating box 700 and the surface area of back face wall 730, and the longitudinal axis represents the deflection of casing.At this, if the density of polyurethane is 60kg/m ³, Vacuumed insulation panel 400 filling rate be 40%, the box deformation amount of laterodorsal area ratio (back side, side covering rate) when being 50% be 1.The Deflection Modulus of Elasticity calculating the Vacuumed insulation panel 400 used is 20MPa, based on the measurement result of the Deflection Modulus of Elasticity of the Vacuumed insulation panel of reality use, use the parts larger than the Deflection Modulus of Elasticity (about 6MPa ~ 10MPa) of existing hard polyurethane foams.At this, when changing area ratio (back side, side covering rate), the filling rate of Vacuumed insulation panel is fixed as 40%, if therefore the area ratio (back side, side covering rate) of Vacuumed insulation panel increases, then and the less thick of Vacuumed insulation panel.

In addition, the refrigerator 1 for calculating is an example, assuming that more than 4 (such as 4 or 5 or 6 specifications), internal volume be 500L level, power consumption is about the refrigerator of below 40W.Comprise distance (wall thickness) the average out to 30mm of the plate thickness between outer container 710 and interior case 750, assuming that the thickness of slab of outer container 710, interior case 750 is respectively 1mm, thus the thickness in space 315 (in wall thickness) is 28mm.The density of hard polyurethane foams is 60kg/m ³, Vacuumed insulation panel 400 thermal conductivity be 0.0021(W/mK), the thermal conductivity of hard polyurethane foams is 0.019(W/mK), Vacuumed insulation panel 400 heat-proof quality compared with hard polyurethane foams got well about about 10 times.

In figure 21, transverse axis represents that Vacuumed insulation panel 400 is relative to the area ratio (laterodorsal Vacuumed insulation panel covering rate) shared by side walls and back face wall surface area altogether, and the longitudinal axis represents the box deformation amount (amount of inclining of casing) when being applied with predetermined load to the heat insulating box 700 with shutter door.At this, the deflection of casing represent sidewall in the side of distance such as heat insulating box above about about 1/4 the deflection of height and position left and right directions of the sidewall upper of heat insulating box when being applied with predetermined load along general horizontal direction when observation front openings portion, front (laterally, be left and right directions).

Known in figure 21, the area ratio of Vacuumed insulation panel 400 is larger, and box deformation amount is less.When making the area ratio at side/back side (laterodorsal Vacuumed insulation panel covering rate) be more than 70%, the rate of change of box deformation amount diminishes.That is, be about 70% to the area ratio at side/back side, if area ratio becomes large, then box deformation amount sharply diminishes, but when the area ratio at side/back side becomes more than 70%, even if area ratio becomes greatly, box deformation amount changes hardly.Therefore, when the area ratio (laterodorsal Vacuumed insulation panel covering rate) at side/back side is more than 70%, the reduction ratio of the deflection of casing is minimum, even if the side backside area ratio of Vacuumed insulation panel increases, box deformation amount also changes hardly.This laterodorsal area ratio be considered to due to, Vacuumed insulation panel is basic close to saturated for the influence degree of casing intensity.

At this, make the filling rate of Vacuumed insulation panel be fixed as 40% and calculate, if therefore increase the configuration area of Vacuumed insulation panel 400, then the lower thickness of Vacuumed insulation panel 400.Be about 70% to the area ratio at the side/back side of Vacuumed insulation panel, if increase the area ratio at side/back side, compared with the recruitment of the box deformation then caused with the lower thickness of Vacuumed insulation panel, the intensity that configuration area because of Vacuumed insulation panel becomes the casing caused greatly improves the reduction of the box deformation caused more greatly, and the therefore rigidity raising of casing, the deflection of casing reduce.But, when the area ratio at the side/back side of Vacuumed insulation panel exceedes about 70%, the reduction that the recruitment that the intensity of the casing caused because of the lower thickness of Vacuumed insulation panel reduces the box deformation caused and the intensity becoming the casing caused greatly because of the configuration area of Vacuumed insulation panel improve the box deformation caused is same degree, and the minimizing degree of the deflection of casing diminishes.

In addition, when being made the lower thickness of Vacuumed insulation panel by the configuration area ratio (covering rate) of increase Vacuumed insulation panel, the thickness of polyurethane foam is thickening.Be about 70% to configuration area ratio, the thickness of Vacuumed insulation panel is more than predetermined thickness, therefore the reduction of the thickness of Vacuumed insulation panel is compared, the impact of recruitment on the intensity of heat insulating box of area ratio is larger, box deformation amount reduces, if but increase the configuration area ratio of Vacuumed insulation panel further, the then less thick of Vacuumed insulation panel, the thickness of polyurethane becomes large, thus the impact of recruitment on the intensity of heat insulating box of the configuration area ratio of the recruitment of the thickness of polyurethane and Vacuumed insulation panel becomes equal, the minimizing degree of box deformation amount diminishes.

Therefore, if the area ratio (back side, side covering rate) at the side/back side of Vacuumed insulation panel 400 is set as more than predetermined value (70%), just casing intensity can be obtained, therefore, it is possible to obtain the high casing of reliability.In addition, if the area ratio at the side/back side of Vacuumed insulation panel is set as more than predetermined value (70%), then become the region that box deformation amount changes hardly, even if therefore the configuration area of Vacuumed insulation panel produces uneven, the deflection of casing also changes hardly, therefore, it is possible to obtain high strength, aesthetic appearance is good, reliability is high heat insulating box, refrigerator, showcase, equipment.If make the covering rate of Vacuumed insulation panel 400 be more than predetermined value (more than 60%) and the area ratio at the side/back side of Vacuumed insulation panel 400 be set as more than the 2nd predetermined value (70%), then heat-proof quality improves, and box deformation amount can be reduced, therefore, it is possible to obtain heat-proof quality is large, reliability is high and energy-conservation refrigerator, showcase, equipment.

At this, if make the thickness of Vacuumed insulation panel fix and expand the configuration area of Vacuumed insulation panel 400, then the covering rate of Vacuumed insulation panel, filling rate all can increase, if but the filling rate of Vacuumed insulation panel 400 increases, then cost increases, therefore do not change filling rate and by increasing covering rate and improving the intensity of heat insulating box 700 time cost lower, and can increase the configuration area of Vacuumed insulation panel, therefore heat-insulating efficiency improves.Therefore, being more than 40% by making the filling rate of Vacuumed insulation panel 400, making the area ratio at side/back side (laterodorsal Vacuumed insulation panel covering rate) be more than 70%, the intensity of heat insulating box can be guaranteed with low-cost high-efficiency.Therefore, if the area ratio (laterodorsal Vacuumed insulation panel covering rate) at the side/back side of Vacuumed insulation panel is set as the 2nd predetermined value (be the reduction ratio of the deflection of heat insulating box diminish area ratio, be such as about 70%) more than, just can thinning heat insulating box 700 wall thickness (thickness of thinning polyurethane), increase the internal volume of storeroom.The configuration area (laterodorsal Vacuumed insulation panel covering rate) of the Vacuumed insulation panel 400 of sidewall 790 and back face wall 730 is larger, the deflection of heat insulating box 700 is less, therefore can increase the intensity of heat insulating box 700, can high strength be provided and the good heat insulating box 700 of heat-proof quality, refrigerator 1, possess the equipment of heat insulating box.

(polyurethane physical property)

At this, the physical property of hard polyurethane foams, the characteristic being filled in heat insulating box 700 is described.Hard polyurethane foams, by increasing free foaming density, can provide the heat insulating box 700 that the intensity stabilization after foaming, outward appearance are good, quality is high.

At this, free foaming density refers to, the density of hard polyurethane foams when not making polyurethane foam in the airtight space such as casing but make polyurethane foam in the container opened etc. under open mode.And in fact, due to foaming in the airtight narrow space of polyurethane in heat insulating box 700, expand, therefore foaming in the airtight narrow space such as heat insulating box 700, the density of polyurethane expanded are larger than the free foaming density of the polyurethane foaming in the open state, expand.

By improving the density of the hard polyurethane foams after foaming, as illustrated in figure 16, Deflection Modulus of Elasticity can be increased, but make polyurethane stock solution flow directly into heat insulating box 700 carry out filling to increase density time, for the polyurethane that the expansion ratio used now is little, free foaming density is little of 26 ~ 28kg/m ³expansion ratio is little, if to there is size not for the stream thickness of part of therefore polyurethane flowing, then foaming degree is uneven, near inlet 703,704 and terminal part (position away from inlet) polyurethane density easily produce inequality, be difficult to obtain stable intensity.

In the present embodiment, by using existing (the such as about 25 ~ 28kg/m of free foaming density ratio ³) (such as free foaming density is about 30 ~ 45kg/m to large hard polyurethane foams ³), even if exist at the stream thickness of the part of polyurethane flowing, a little size is also can stably not foam because expansion ratio is large, can reduce the inequality of the density after foaming.Therefore, the density being easy to the polyurethane after making foaming is roughly even.

The foaming body that hard polyurethane foams is such, have bubble in inside, density is less, and bubble is more, and heat insulation effect is higher.Therefore, in prior art, heat insulating box 700 makes by the density after the foaming of hard polyurethane foams that uses is about 25 ~ 28kg/m ³the hard polyurethane foams of little density.Want to use this existing polyurethane foam make Deflection Modulus of Elasticity for more than 15MPa to guarantee the intensity of heat insulating box 700 time, such as, in wall, thickness is 28mm, the thickness of the polyurethane after the thickness of removing Vacuumed insulation panel is in the heat insulating box of 8mm, must inject, the lucky loading of packing ratio polyurethane (is polyurethane amount when can not apply irrational load etc. and just fill hard polyurethane foams in the casing becoming object, density after foaming easily becomes even) how polyurethane, density easily produces inequality.

And then, due to the polyurethane that must inject, the lucky loading of packing ratio is many, therefore pressurization or prolongation filling time when polyurethane injects is needed, thus polyurethane is from the junction surface of the profile of heat insulating box 700, shutter door etc., and gap (such as the junction surface of outer container 710 and interior case 750) spills, the polyurethane of the scheduled volume needed for (cannot fill) cannot be injected, be difficult to guarantee that the density of the hard polyurethane foams after being filled into casing is than predetermined value (such as 60kg/mm ³) large density.In addition, if polyurethane spills from the profile of casing, just need the operation of removing the polyurethane spilt, activity duration or built-up time need to increase, and cause cost rising, aesthetic appearance reduction.Therefore, the density of the polyurethane after being filled into heat insulating box in prior art is less than 60kg/m ³, be about 25 ~ 30kg/m ³, up to about 55kg/m ³below.

At this, in the present embodiment, the amount that have studied the expanded material by comprising in minimizing polyurethane stock solution etc. increases free foaming density.Such as the thickness of polyurethane be 8mm(remove Vacuumed insulation panel thickness after polyurethane stream thickness be about 8mm) heat insulating box 700 in, by free foaming density is set as predetermined value (30kg/m ³above, preferred 35kg/m ³above), can make the density under lucky loading (do not apply the ground such as irrational load be filled into casing after the density of polyurethane) compare 60kg/m ³greatly, the Deflection Modulus of Elasticity of hard polyurethane foams can be made to be more than 15MPa.Therefore, the density unevenness of polyurethane can be eliminated, the problem of heat insulating box that polyurethane spills and so on, can obtain that reliability is high, the heat insulating box of high strength 700, refrigerator 1, showcase, possess the equipment of heat insulating box.

At this, worry because making the free foaming density ratio predetermined value of hard polyaminoester large, increase the polyurethane density after foaming to the impact of heat-proof quality, but illustrated by Figure 17 ~ Figure 21, such as the thickness of the polyurethane at the configuration position of Vacuumed insulation panel 400 is set as below predetermined value (below 11mm, or below 6mm), or thickness in the thickness/wall of polyurethane is set as predetermined value (0.3) below, or when the filling rate of Vacuumed insulation panel 400 being set as preset range (less than more than 40% 90%), the impact of the heat-proof quality on heat insulating box can be reduced (to heat insulating box 700, the impact of the heat-proof quality of the heat insulating box of shutter door).In addition, when making the thickness of polyurethane be below 11mm, be predetermined value (such as 35kg/m by making free foaming density ³) more than, the lucky loading (lucky loading can be adjusted) not causing polyurethane to spill can be set to.

The heat insulating box 700 of present embodiment can make the wall ratio of heat insulating box 700 existing thin, in addition, guarantee predetermined intensity, when filling polyurethane, polyurethane is also difficult to spill from profile, required quality can be met, can provide energy-conservation, the heat insulating box 700 of internal volume excellent in efficiency.Namely, the appearance and size of the equipment not changing heat insulating box 700 or refrigerator 1 or possess heat insulating box just can make the reserve storage volume of heat insulating box (being such as case internal volume or reservoir volume when refrigerator) than greatly existing, the collecting article that the inside can increasing heat insulating box 700 compared to existing technology can be stored.Therefore, it is possible to obtain that user is easy to use, thermal insulation good, high strength and the high heat insulating box 700 of reliability or refrigerator 1 or possess the equipment of heat insulating box.In addition, when the storage volume settings of indoor (in storeroom) is become equal with prior art, the amount that appearance and size can be enable correspondingly to reduce wall thickness reduce.

At this, refrigerator 1 possesses the cooling device for cooling the air (cold air) to multiple storeroom supply such as refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5.This cooling device is made up of compressor 12, refrigerant piping (such as condensation pipe arrangement 725), decompressor (expansion valve, capillary etc.), cooler 13 etc., forms freeze cycle.Form the compressor 12 in the inscape of this freeze cycle, decompressor is located in the Machine Room 1A that formed in the back underside (also can be on the upside of the back side) of heat insulating box 700 forming refrigerator 1.Condensation pipe arrangement 725 is located at the such as sidewall 790 of heat insulating box 700 or back face wall 730 or top wall 740.By forming the fan grill etc. of reserve accommodation space at the back side of storeroom, the storeroom side of wall 730 is provided with and covers with the back side of the parts of interior case 750 split overleaf, and cooler 13 is located in the cooler room 131 that formed between the back side cap assemblies such as interior case 750 and fan grill.In addition, in this cooler room 131, be also provided with the circulating cold air fan 14 for each storerooms such as refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5 of being blown to by the chilled air of cooler 13 (cold air).In addition, be provided with in the top wall 740 of heat insulating box 700 or the top (or substantial middle height and position of back face wall 730) of back face wall 730 and control substrate room 31, in control substrate room 31, be provided with control device 30, the motion that this control device 30 carries out controlling the rotating speed of compressor 12 or circulating cold air fan 14 etc. controls or the temperature inside the box control etc.

At the refrigerator 1 formed like this, the gas refrigerant of the HTHP sent by the compressor 12 be configured in the 1A of Machine Room, pass through at refrigerant piping (such as condensation pipe arrangement) 725 and be condensed, become the liquid refrigerant of cryogenic high pressure, the liquid refrigerant of cryogenic high pressure is reduced pressure into the gas-liquid two-phase cold-producing medium of low-temp low-pressure by decompressor, when arriving cooler 13, become the low temperature of such as less than-20 DEG C.Air in the gas-liquid two-phase refrigerant cools cooler room 131 of this low-temp low-pressure, and this cooled air is supplied to each storerooms such as refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5 by circulating cold air fan 14, thus the storerooms (or the collecting article received in these storerooms) such as refrigerated compartment 2, refrigerating chamber 6, vegetable compartment 5.On the other hand, cool the gas-liquid two-phase cold-producing medium of the low-temp low-pressure of the air in cooler room 131, evaporated by the air heat in cooler room 131, become the gas shape cold-producing medium of low pressure and be inhaled into compressor 12 once again and compressed.

As mentioned above, in the refrigerator 1 of present embodiment, make Vacuumed insulation panel 400 relative to the internal capacity of the door inner space of the space 315 formed between outer container 710 and interior case 750 and shutter door total volume shared by ratio and the filling rate of Vacuumed insulation panel be predetermined value (such as 40% ~ 80%).Therefore, even if thickness (distance (thickness) such as between outer container 710 and interior case 750 or the thickness of shutter door) is thinner than prior art in the wall of heat insulating box 700, also heat-proof quality can be guaranteed.Therefore, in the refrigerator 1 of present embodiment, the heat-proof quality of heat insulating box 700 is improved, thus cold air in multiple storeroom 2,3,4,5,6, collecting article are not easy to warm, and therefore can shorten the duration of runs of the compressor 12 for cooling or reduce the air quantity of fan.Therefore, it is possible to the air quantity of the air (cold air) needed for the cooling in storeroom 2,3,4,5,6 is suppressed less, the rotating speed of compressor 12 can be reduced or extend the running OFF time, therefore can carry out energy-conservation running.Therefore, in the refrigerator 1 of present embodiment, can be more energy-conservation than existing.In addition, refrigerator 1 does not change appearance and size just can expand reservoir volume (case internal volume) compared to existing technology, can increase the collecting article can stored in storeroom compared to existing technology, therefore can obtain refrigerator easy to use, equipment.

In addition, if the refrigerating chamber 6 maximum with the temperature difference of outer gas to be configured at the substantial middle position of above-below direction, then can suppress from above and the heat being derived from outer gas that enters towards refrigerating chamber 6, the hot entering surface that heat therefore can be made to enter refrigerating chamber 6 from outer gas cut is 4 (shutter door above, left surface, right flank, these 4 faces, the back side).Therefore, energy-conservation refrigerator 1 can be obtained.

In addition, according to the present embodiment, the Deflection Modulus of Elasticity of the hard polyurethane foams being filled in space 315 and door inner space is made to be more than 15.0MPa, therefore the casing intensity of heat insulating box 700 can meet predetermined intensity, thus heat insulating box 700 can be suppressed to be out of shape because of cause crooked of the weight that cannot tolerate collecting article.Therefore, heat insulating box 700 can be suppressed crooked and shutter door is above tilted, the deterioration of outward appearance can be prevented.In addition, can suppress to stagger to the position of the seal member sealed between shutter door and the front openings portion of heat insulating box and produce gap thus make the situation that the air (cold air) in refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5, ice-making compartment 3, switch room 4 spills to the outside of heat insulating box 700, refrigerator 1, thus more energy-conservation refrigerator, equipment can be obtained.

In addition, about the distribution of the filling rate of the Vacuumed insulation panel 400 in space 315 or door inner space, also according to the temperature difference of outer gas and each storeroom, and in space 315 or door inner space, the filling rate of Vacuumed insulation panel 400 can be changed according to preposition.

Such as, refrigerating chamber 6(or ice-making compartment 3, switch room 4 as low temperature chamber), the temperature difference of the temperature in its storeroom and outer gas is maximum.Therefore, can make to be in the left surface of the heat insulating box 700 of refrigerating chamber 6 scope in opposite directions, right flank, the back side and above the Vacuumed insulation panel 400 of (shutter door) filling rate than with the wall of other storerooms (such as refrigerating chamber 2, the vegetable compartment 5 of hot room) scope in opposite directions (such as left surface, right flank, the back side and above (shutter door)) large (such as more than 60%).By such formation, the heat to the minimum low temperature chamber of temperature and refrigerating chamber 6 can be suppressed to invade, more energy-conservation refrigerator 1, equipment can be obtained.

Such as, outer temperature degree be such as 30 DEG C time, become such as more than 40 DEG C in the 1A of Machine Room.The temperature controlling substrate room 31 also rises to such as more than 40 DEG C.That is, Machine Room 1A and wall, partition wall 24 between control substrate room 31 and the storeroom of position in opposite directions, compare the wall of other parts, partition wall 24, larger with the temperature difference in storeroom.Therefore, thermal capacitance easily invades at Machine Room 1A, the storeroom controlling configuration near substrate room 31.Therefore, at the wall, the partition wall 24 that are configured at Machine Room 1A or control between substrate room 31 and storeroom, the filling rate of Vacuumed insulation panel 400 can be made to improve heat-proof quality greatly than other walls, partition wall 24.Such as at the wall, the partition wall 24 that are configured at Machine Room 1A or control between substrate room 31 and storeroom, the filling rate of Vacuumed insulation panel 400 can be made to be more than 60% (back side, the side covering rate making Vacuumed insulation panel 400 is more than 70%), and to make the filling rate of the Vacuumed insulation panel 400 of other walls, partition wall 24 be more than 40% (less than 90%).By such formation, the hot Machine Room 1A high from temperature can be suppressed, control substrate room to the intrusion of neighbouring storeroom, refrigerator 1 energy-saving more can be made.

The heat insulating box 700 of present embodiment such as may be used for the heater of heating water and possesses the water storage device of the tank storing up the water stayed by this heating devices heat.By the inside batch tank at heat insulating box 700, can be more heat insulation by tank than existing little heat insulating box 700 by appearance and size, water storage device space saving can be made.In addition, as long as the equipment (such as refrigerator, showcase, refrigerator, hot-water supply, hot shot water machine, aircondition etc.) that present embodiment has the thermal wall of band Vacuumed insulation panel just can be applied.

In embodiments of the present invention, concavo-convex etc. without the need to arranging at Vacuumed insulation panel 400, also without the need to making the core in inclosure outsourcing material be the shape of the concaveconvex shape along outsourcing material, therefore Vacuumed insulation panel 400 can use flat object, so, core has the shot-like particle of mobility without the need to using, the fiber-like such as inorfil, the organic fiber cores such as glass fibre can be used, and do not need to arrange concavo-convex etc. complicated processing at outsourcing material, thus low cost, treatability is good, heat-proof quality is high heat insulating box, refrigerator, equipment can be obtained.

At this, in the present embodiment, the 3rd sandwiched parts can be identical with the 1st sandwiched parts.In addition, the 2nd sandwiched parts also can be identical with the 1st sandwiched parts.

(effect that embodiment plays)

As mentioned above, in the present embodiment, formed by outer container 710 and interior case 750, at least there is sidewall 790, back face wall 730, having in the heat insulating box 700 of opening portion above, possess: protuberance 450, be formed at the corner part of back face wall 730 and sidewall 790, forwardly give prominence to side, opening portion relative to back face wall 730, recess 440(also can be the 2nd recess 441), in formation back face wall 730, case 750 is formed, and caves in rearward from front face side read fortune for protuberance 450, with flat Vacuumed insulation panel 400, at least arrange between case 750 and outer container 710 in formation back face wall 730, to be configured at and in recess 440 position in opposite directions between case 750 and outer container 710, at least large than the width (representing with the scope W of recess 440 in Fig. 8) of recess 440 on width (or length direction), protuberance 450 is formed as overlapping with predetermined length X with Vacuumed insulation panel 400, in Vacuumed insulation panel 400 and formation recess 440 between case 750, and when filling bonding agent as sandwiched parts between Vacuumed insulation panel 400 and the interior case 750 forming protuberance 450, even if the thickness of the bonding agent between Vacuumed insulation panel 400 and interior case 750 is less, due to protuberance 450 and Vacuumed insulation panel 400 overlap length X, therefore corresponding to the amount of the length X of overlap, the bonding thickness of bonding agent (such as the hard polyurethane foams of foaming heat insulation part) increases, Vacuumed insulation panel 400 via the bonding agent in protuberance 450 and can form case 750(or outer container 710 in recess 440) bonding securely.In addition, the interior case 750 forming recess 440 and the interior case 750 forming sidewall 790 also can be bonding securely via protuberance 450.Therefore, even if the thickness of the bonding agent between the Vacuumed insulation panel 400 at thinning recess 440 place and interior case 750, also via the large protuberance 450 of bonding agent thickness, recess 440, Vacuumed insulation panel 400, sidewall 790 can be integrally formed, therefore can the wall thickness of recess 440 of thinning configuration Vacuumed insulation panel, and the intensity of casing or wall can be improved.

At this, if the bonding agent as sandwiched parts is used as the hard polyurethane foams of the foaming heat insulation part with self-adhesiveness, even if then the thickness of the hard polyurethane foams between Vacuumed insulation panel 400 and interior case 750 is set to and is thinned to predetermined below 11mm, also due to protuberance 450 and Vacuumed insulation panel 400 overlap length X, corresponding to the amount of the length X of overlap, the thickness of the hard polyurethane foams between Vacuumed insulation panel 400 and interior case 750 can be made to increase, Vacuumed insulation panel 400 can via the hard polyurethane foams in protuberance 450 and interior case 750(or outer container 710) bonding securely.In addition, even if the thickness of the hard polyurethane foams between the Vacuumed insulation panel 400 of thinning and recess 440 position in opposite directions and interior case 750, also can be integrally formed via the hard polyurethane foams in protuberance 450 and sidewall 790 with the Vacuumed insulation panel 400 of recess 440 position in opposite directions, even if therefore the wall thickness of the part of thinning formation recess 440, also can improve the intensity of casing intensity or wall.

In addition, formed by outer container 710 and interior case 750, the surrounding of wall 730 has at least one surrounding wall (such as sidewall 790 overleaf, roof 740, underside wall 780, partition wall 24), have in the heat insulating box 700 of opening portion above, back face wall 730 has the protuberance 450 formed at the corner part with surrounding wall, with the recess 440(caved in rearward for protuberance 450 from front face side read fortune or the 2nd recess 441), and possess be configured at and recess 440(or the 2nd recess 441) between the interior case 750 of position in opposite directions and outer container 710 and at least on width or length direction than the scope W of the width P(recess of recess) large flat Vacuumed insulation panel 400, protuberance 450 is formed as predetermined length X overlapping with Vacuumed insulation panel 400, in recess 440 position in opposite directions between case 750 and Vacuumed insulation panel 400, and and between the interior case 750 of protuberance 450 position in opposite directions and Vacuumed insulation panel 400, if fill bonding agent as sandwiched parts, even if the less thick of the bonding agent then between Vacuumed insulation panel 400 and interior case 750, also due to protuberance 450 and Vacuumed insulation panel 400 overlap length X, corresponding to the amount of the length X of overlap, the bonding thickness of bonding agent (such as the hard polyurethane foams of foaming heat insulation part) can be made to increase, Vacuumed insulation panel 400 via the bonding agent in protuberance 450 and can form case 750(or outer container 710 in recess 440) bonding securely.In addition, interior case 750 and at least one surrounding wall (such as sidewall 790, roof 740, underside wall 780, partition wall 24) of forming recess 440 also can be bonding securely via protuberance 450.Therefore, even if the thickness of the bonding agent between the Vacuumed insulation panel 400 at thinning recess 440 place and interior case 750, also via the protuberance that sandwiched component thickness (bonding agent thickness) is large, recess 440, Vacuumed insulation panel 400, at least one surrounding wall (such as sidewall 790, roof 740, underside wall 780, partition wall 24) can be integrally formed, therefore can the wall thickness of recess 440 of thinning configuration Vacuumed insulation panel, and the intensity of casing or wall can be improved.

In addition, surrounding wall is for being connected and the sidewall 790 of forming chamber (such as storeroom) with back face wall 730, roof 740, underside wall 780, during any one of partition wall 24, even if the sandwiched parts between the Vacuumed insulation panel 400 at thinning recess 440 place and interior case 750 and the thickness of bonding agent, the Vacuumed insulation panel 400 being configured at recess 440 also can via the sandwiched parts (bonding agent) of protuberance and at least one surrounding wall (such as sidewall 790, roof 740, underside wall 780, partition wall 24) be integrally formed, even if the therefore wall thickness of the part of thinning formation recess, also the intensity of casing or wall can be improved.In addition, if use hard polyurethane foams as sandwiched parts (bonding agent), then predetermined heat-proof quality can also be improved.

In addition, as sandwiched parts (bonding agent), if to use before filling as having the liquid of mobility or two-phase state, fill post-foaming and play the foaming heat insulation part with self-adhesiveness of function as bonding agent, even if the gap smaller then between the Vacuumed insulation panel 400 at recess 440 place and interior case 750, also narrow gap can be flowed into liquid condition or two-phase state, therefore can fill sandwiched parts (bonding agent) equably, adhesive strength or constant intensity can be guaranteed.Even if therefore thinning wall thickness also can guarantee the intensity of casing.In addition, also play function as thermal insulation barriers, therefore heat-proof quality also improves.

In addition, when using bonding agent as sandwiched parts, when bonding agent is the hard polyurethane foams as foaming heat insulation part, in the part (such as recess 440 etc. are configured with the wall of Vacuumed insulation panel 400) of the thinner thickness of polyurethane, effect as thermal insulation barriers reduces, as long as but be used as the hard polyurethane foams of sandwiched parts as in the present embodiment as bonding agent.In addition, can guarantee that part (such as not configuring the wall etc. of Vacuumed insulation panel 400) that the thickness of polyurethane is thicker can obtain the effect as thermal insulation barriers, therefore can use as thermal insulation barriers, therefore, it is possible to guarantee intensity and the heat-proof quality of casing simultaneously, high-performance can be obtained and the high heat insulating box, refrigerator, equipment etc. of reliability.In addition, hard polyurethane foams has this speciality of the unexistent self-adhesiveness of other thermal insulation barriers material, even if therefore do not use other bonding agents, also by directly foaming on the surface of object (interior case 750, Vacuumed insulation panel 400, outer container 710) and forming the thermal insulation layer bonding to object securely, can obtain cementability and thermal insulation simultaneously.

In addition, even if the thickness being filled in the bonding agent as sandwiched parts between Vacuumed insulation panel 400 and interior case 750 is less than the thickness of Vacuumed insulation panel 400, also can guarantee wall intensity or casing intensity by Vacuumed insulation panel 400, therefore thinningly can possess the wall thickness of the wall of Vacuumed insulation panel 400.

In addition, if the thickness of the bonding agent as sandwiched parts (such as hard polyurethane foams) of filling between case 750 and Vacuumed insulation panel 400 in recess 440 position is in opposite directions set as below 11mm, the less thick of hard polyurethane foams then can increase the Deflection Modulus of Elasticity of hard polyurethane foams, even if therefore also can improve intensity.Therefore, even if reduce wall thickness also can improve casing intensity.

In addition, by back face wall 730, sidewall 790, upper wall 24(or roof 740) and lower wall 24(or underside wall 780) to be formed and in the heat insulating box of front openings, possess: Vacuumed insulation panel 400, formed back face wall 730 inner face in case 750 and formed back face wall 730 outside outer container 710 between or formed sidewall 790 inner face in case 750 and formed sidewall 790 outside outer container 710 between arrange; With sandwiched parts, fill between Vacuumed insulation panel 400 and interior case 750 or enclose or apply or arrange, by Vacuumed insulation panel 400 with interior case 750 is bonding or cementation or fixing, sandwiched parts are polyurethane foam, the thickness of sandwiched parts is below 11mm, therefore the reduction of the thickness of polyurethane foam the Deflection Modulus of Elasticity of polyurethane foam can be increased, even if thus also can improve intensity.Therefore, even if reduce wall thickness also can improve casing intensity.

In addition, when there is the hard polyurethane foams of self-adhesiveness as sandwiched parts (bonding agent) use and [(thickness of sandwiched parts)/(thickness of the thickness+Vacuumed insulation panel of sandwiched parts)] be set as below 0.3, the composite guide heating rate of the wall formed by the composite component possessing Vacuumed insulation panel 400 and hard polyurethane foams can be reduced, even if therefore reduce wall thickness also heat-proof quality can be improved.

In addition, directly bonding by the 2nd bonding agent as the 2nd sandwiched parts beyond the foaming heat insulation such as PUR or double faced adhesive tape part between Vacuumed insulation panel 400 and outer container 710, using and recess 440(or the 2nd recess 441) thickness of the bonding agent (such as hard polyurethane foams) as the 1st sandwiched parts of filling between the interior case 750 of position in opposite directions and Vacuumed insulation panel 400 is set as below 11mm, when the thickness of the 1st sandwiched parts/(thickness of the thickness+Vacuumed insulation panel of the 1st sandwiched parts) is set as below 0.3, using Vacuumed insulation panel 400 by filling the bonding agent as the 1st sandwiched parts after directly bonding to outer container 710 as the 2nd bonding agent of the 2nd sandwiched parts between Vacuumed insulation panel 400 and interior case 750, therefore assembleability improves.In addition, between outer container 710 and Vacuumed insulation panel 400 by beyond the foaming heat insulation such as PUR or double faced adhesive tape part the 2nd bonding agent direct bonding time, can wall thickness be reduced.In addition the thickness therefore reducing hard polyurethane foams, the Deflection Modulus of Elasticity of the hard polyurethane foams as the 1st sandwiched parts can be increased, even if also can improve intensity.Therefore, even if reduce wall thickness also can improve casing intensity.In addition, the composite guide heating rate of the wall formed by the composite component possessing Vacuumed insulation panel 400 and hard polyurethane foams can be reduced, even if therefore reduce wall thickness also heat-proof quality can be improved.

In addition, Vacuumed insulation panel 400 is at least configured at back face wall 730, when the configuration area of Vacuumed insulation panel 400 that configures of wall 730 and sidewall 790 is more than 70% relative to the ratio of the surface area of back face wall 730 and sidewall 790 overleaf, casing intensity can be improved, reduce the deflection of casing.Therefore, it is possible to obtain high strength and the high heat insulating box, refrigerator, hot water supply device, equipment etc. of reliability.

Namely, Vacuumed insulation panel 400 is at least configured at back face wall 730, and be configured to by Vacuumed insulation panel 400 to make wall 730 or sidewall 790 configure overleaf Vacuumed insulation panel 400 to support or oppose to face the wall and meditate the total of the projected area of 730 or sidewall 790 to become the ratio of more than 70% relative to back face wall 730 and sidewall 790 total surface area altogether, therefore casing intensity improves, and can reduce the deflection of casing.Therefore, it is possible to obtain high strength and the high heat insulating box, refrigerator, hot water supply device, equipment etc. of reliability.

In addition, in the heat insulating box 700 with outer container 710 and interior case 750, Vacuumed insulation panel 400 relative between outer container 710 and interior case 750 formed space 315 volume shared by volume be more than 40% time, casing intensity improve, the deflection of casing can be reduced.Therefore, it is possible to obtain high strength and the high heat insulating box, refrigerator, hot water supply device, equipment etc. of reliability.

In addition, by arranging protuberance 450 at the corner part of sidewall 790 and back face wall 730 and be configured with Vacuumed insulation panel 400 between outer container 710 and interior case 750, casing intensity is improved, therefore concavo-convex etc. without the need to arranging at Vacuumed insulation panel 400; In addition, without the need to the core enclosed in outsourcing material is formed as concaveconvex shape, therefore Vacuumed insulation panel 400 can use tabular thing, thus the fiber-like such as organic fiber or inorfil core can be used as the core of Vacuumed insulation panel 400, therefore, core waits complicated shape without the need to using the shot-like particle with mobility to be formed as concavo-convex, and outsourcing material does not need to arrange concavo-convex etc. complicated processing yet, thus heat insulating box, refrigerator, the equipment that the good and heat-proof quality of low cost, treatability improves can be obtained.
