Description

Refrigerator

The present invention relates to a kind of structure of refrigerator body of thermal insulating box, especially the sort of for the body of thermal insulating box structural strength is reduced to the improved refrigerator in addition of (partition) panel (front plate) or outer container at interval.

The body of thermal insulating box of refrigerator by metal outer container, resinous in case and the foamed thermal insulating that is filled between inside and outside two casees constitute.In order to increase the case internal volume of the body of thermal insulating box that identical depth size and same widths size are arranged, the measure of generally taking is the space that dwindles the Machine Room, perhaps reduce the thickness in each wall of body of thermal insulating box and next door, but in these measures, guarantee the method for case internal volume with the left and right sides wall thickness that reduces body of thermal insulating box, can produce such problem, promptly because the thickness of sidewall, the particularly reduced thickness because of heat-insulating material reduce the structural strength of body of thermal insulating box.

Therefore, in order to ensure structural strength, generally take to increase the thickness of outer boxboard, perhaps setting reinforcement in the weak part of the part that is subjected to the load effect easily and structure increases structural strength.

As shown in Figure 5, front-end edge 3 places at the body of thermal insulating box 1 of general refrigerator, form groove on the face of a side joining with heat-insulating material, refrigerant pipe 5 is set in this groove, the hyperthermia induced refrigerant flow is crossed this pipe, can prevent body of thermal insulating box opening edge portion dewfall (for example Japanese patent gazette special fair 3-33996 number disclosed like that).This refrigerant pipe 5 is equivalent to condenser (condenser), and the HTHP refrigerant of discharging from the compressor (not having expression the figure) of body of thermal insulating box 1 bottom imports cooler (being evaporimeter (evaporator)) by condenser.That part of 5B (be " U " font usually, thereby be called " U " font part) that is connected with refrigerant pipe 5 in being contained in this groove also be configured in refrigerator inside up and down isolated next door and in front opening part with each storeroom up and down on the front of isolated space before member (also not having expression among the figure).

Figure 14 is the amplification decomposition figure with refrigerant pipe in the pre-structure 5 and " U " font part 5B coupling part (part shown in the circle A among Fig. 5 and Fig. 6), and Figure 15 is the horizontal sectional view after several parts shown in Figure 14 are assembled.And Figure 16 is the front elevation of the above-mentioned coupling part of outer container and interior case assembling back.

In Figure 14～Figure 16, the body of thermal insulating box 1 of refrigerator is made of outer container 7, interior case 9 and foamed thermal insulating, and the intermediate bulkheads (among the figure there be not expression) that the inner space of interior case 9 is partitioned into each chamber is arranged on the B part of Figure 14, continuous and outside flange 13 is arranged on the front-end edge of interior case 9.

The metallic plate that sprays paint in advance is bent into an outer container of shape structure 7, forms groove 10 and double-deck front flange 11B and the back flange 11A that concaves at the front openings circumference of outer container 7.Groove 10 is used for the refrigerant pipe 5 and the outward flange 13 of packing into above-mentioned; Double-deck front flange 11B by front chimb 11a and the inboard of this front chimb 11a and separate with it some at interval the inside chimb 11b that turns back of P constitute; Back flange 11A and the inside chimb 11b continuously and its with the inside chimb 11b between the above-mentioned groove 10 of formation.

In addition, the step part 15A that forms on interval panel 15 two ends that cover the front, next door also is inserted in the groove 10.At the mid portion of the above-below direction of the back flange 11A of groove 10 (in more detail, be the part of configuration next door and space before member) form big otch 17, from otch 17, " U " font part 5B of refrigerant pipe 5 is set continuously to next door and space before member front in groove 10.

In the position of this big otch 17 is corresponding, also form roughly " " word shape recess 19 that becomes two ladders to depth direction on the outward flange 13 of case 9.By forming recess 19, just form the roughly protuberance 21 of " " word shape in the inside of interior case 9.This protuberance 21 is inserted into 17 li at above-mentioned big otch, and case 9 is inserted on the assigned position of outer container 7 in just making, and guarantees the space size that filling heat insulator is used between interior case 9 and the outer container 7.

So just on the flange 11A of back, form bigger otch 17, but for foamed thermal insulatings such as polyurathamc being filled between outer container 7 and the interior case 9, heat-insulating material can not spilt from otch 17, just must stop up the gap of otch 17 and 21 generations of protuberance with containment member.In addition, in outer case 7 one sides of above-mentioned interval panel 15, the hingen 23 (as representing with double dot dash line on Figure 15) that makes the refrigerator door open-close action is set.

Owing to form aforesaid big otch 17, the front-end edge of Yan Xu outer container 7 becomes discontinuously in the part that forms otch 17 along the vertical direction, makes the intensity reduction of this part, thereby must strengthen the intensity of this part with reinforcing material.Therefore,, install hingen pressing plate installing plate 25, hingen pressing plate 27 is installed from the face side of interior case 9 as reinforcing material from the inside side of interior case 9 at the fore-end of the B of Figure 14.On the case 9, also hingen pressing plate 27 is fastened on the panel 15 of interval in bolt, Screw or screw thread above-mentioned member 25 and 27 being fastened on then with bolt, Screw or screw thread.

In addition, also just like Japanese patent gazette special public clear 63-16025 number disclosed like that, with the front of the end face and the back flange 11A on the position, side dogleg section corresponding upper front end turning of outer container 7, set positive L-shaped enhancing accessory (" L " shape reinforcement plate), perhaps the thickness of interval panel 15 is made also thicklyer, strengthened outer container intensity thus than the thickness of previous interval panel and outer container.Also can further strengthen the fastening structure of Machine Room inner compressor support of body of thermal insulating box bottom or the structure that Screw quantity that increase is used for fixing the outer container front-axle beam strengthens outer container.

But, above-mentioned these structures in the past, that part of component number of guiding to next door and space before member front owing to refrigerant pipe 5 from outer container groove 10 inside is more, thereby the manufacturing cost of each parts is increased; Along with component number increases, the number in man-hour of processing increases, and assembly cost increases.In addition,, therefore must partial enhanced separate up and down because the 25 spaced apart configurations of hingen pressing plate installing plate are a plurality of, thus the opening edge portion that can not fully strengthen outer container 7 above-below directions.

In addition, the step part 15A at panel 15 two ends is contained in the groove 10 of outer container 7 at interval, because the step thicknesses of 15A equates that with the bending part thickness of front flange 11B step part 15A is not strengthened.Again because on the weight of door or door pocket added load (i.e. Men load) etc., be added at interval by hingen 23 and make step part 15A be subjected to the pulling force effect on the panel 15 along the direction that comes off, cause step part 15A and front flange 11B or Screw flexural deformation, making at interval, hingen 23 standing parts (following joining part) of panel 15 bend along the direction that comes off, cause a difficulty to open, degradation disadvantage under the sealing property of door.

Because the face (being expressed as joining part in an embodiment) almost parallel with the face of the step part 15A that is contained in 10 li of grooves (being that step part 15A is curved the right angle) of hingen 23 is installed, thereby when step part 15A installs to 10 li of grooves, inside can occur at interval between the front end of chimb 11b and step part 15A.

Like this, when being fixed to interval panel 15 on the outer container 7 with Screw, when perhaps being fixed to hingen 23 on the outer container 7, screwing force by Screw makes the surface of the front flange 11B of outer container 7 be pressed towards the rear, because step part 15A does not contact with the inside of front flange 11B, thereby can not strengthen front flange 11B with step part 15A, and the front flange 11B of outer container 7 is caved in easily, the problem of the appearance damage of making is arranged.

Therefore, as shown in figure 17, if the front end of the step part 15A of interval panel 15 is pressed to the front side again, make it as Figure 18 and shown in Figure 19, chimb 11b joins with the inside, just can support front flange 11B from the inboard, can also improve the intensity of step part 15A self.

But, in this case, because base portion at step part 15A, form the step that thickness equates with the dogleg section thickness of front flange 11B up and down along it, thereby shown in Figure 20 arrow, when step part 15A is inserted into 10 li of grooves, makes the interior case 9 of this step part be pressed towards the rear by " U " font part 5B and be out of shape.Therefore, when the thickness of slab attenuate of interior case 9, have and chap, make the at interval insertion operation of panel 15 also to become to be difficult to the problem of carrying out.

The purpose of this invention is to provide a kind of for obtaining bigger case internal volume, even under the situation of the left and right sides wall thickness of attenuate body of thermal insulating box, the refrigerator that casing intensity does not still reduce.Specifically, the 1st purpose of the present invention is the front flange that strengthens outer container, form the step part that is inserted in the outer container groove at the two ends of metal interval panel, the front chimb of the size of this step part and outer container and the size of space of the inside chimb are identical or slightly bigger; And this step part is forwards tilted gradually, its front end and the inside chimb are joined.

The 2nd purpose of the present invention is to make the intensity raising of the step part of panel at interval, and the upper and lower side at septal surface pallet exponent part forms the rib (rib) that strengthens usefulness for this reason.

The 3rd purpose of the present invention is the otch of flange behind the removal outer container, increase the intensity of the opening edge portion that outer container extends along the vertical direction, for this reason on above-mentioned basis, the inboard of flange behind outer container, cross over the configuration section of next door and space before member, the enhancing accessory is set along the vertical direction.

Below, with reference to accompanying drawing embodiments of the invention are described.

The body of thermal insulating box 1 of refrigerator 20 of the present invention comprises with metal outer container 7, plastic interior case 9 and foamed thermal insulating 31 (with reference to Figure 12 and Figure 13).Above-mentioned metal outer container 7 is that the steel plate Bending Processing of spraying paint that constitutes the refrigerator outside is made; Above-mentioned plastic in case 9 the ABS synthetic resin such as (acrylonitrile butadient styrenes) that constitutes the refrigerator inner surfaces in addition vacuum forming constitute; Above-mentioned foamed thermal insulating 31 is used for being filled in the space of the two formation under the state that interior case is contained in outer container the inside.By the fluon (for example R-22, R-142b, R-141b) of water or non-rule as blowing agent.

With next door 32 inner space of interior case 9 is separated up and down, form respectively the top refrigerating chamber 33 and below refrigerating chamber 34.Lower opening portion at body of thermal insulating box 1 also is installed with the space before member 35 that this opening is separated up and down, and in the back of space before member 35 dividing plate 37 is being set, and 37 bottoms establish vegetable container 36 at dividing plate.Cooler 38 and pressure fan 39 in the refrigerating circulation system are set in the behind of refrigerating chamber 33, deliver in each chamber by 39 cold air that carried out heat exchange with cooler 38 of pressure fan and circulate, the temperature that they are cooled to stipulate separately.In addition, below body of thermal insulating box 1, form Machine Room 41,41 li compressors 42 that refrigerating circulation system is set in the Machine Room.

The open front of the open front of refrigerating chamber 33 and refrigerating chamber 34 and vegetable container 36 is closed tightly by refrigerating chamber door 43, refrigerating-chamber door 44 and vegetable compartment door 45 respectively, can free switch.In Figure 13, the top of vegetable container 36 also is installed with another group space before member 46 and dividing plate 47, and dividing plate 47 bottoms are being provided with the container 48 that is cooled to than about the low zero degree of refrigerated storage temperature.The open front of container 48 is closed by door 49, can free switch.

In above-mentioned each refrigerator 20, interior case 9 has outward flange 13 at front-end edge.This is L font outward flange 13 inserts in the following groove 10, making has certain intervals between outer container 7 and the interior case 9 and chimeric.With inside and outside two casees chimeric states groove 10 is sealed (with reference to Fig. 3).

Outer container 7 comprises outer container body 7A, backplate 7B and bottom panel 7C, and outer container body 7A forms corresponding formation door shape with end face, the left and right side of outer container 7 with the steel plate that sprays paint through bending; Backplate 7B is installed in the back of outer container body 7A; Bottom panel 7C is installed on the bottom of outer container body 7A; There is opening front at outer container 7.Especially the front-end edge of outer container body 7A also be provided with dress refrigerant pipe 5 and above-mentioned in case 9 outward flange 13 usefulness to internal channel 10.

Outer container body 7A also has double-deck front flange 11B and back flange 11A.Double-deck front flange 11B comprises front chimb 11a and the inboard of this front chimb 11a and separate a little interval P and the inside chimb 11b that turns back; Back flange 11A links to each other with the inside chimb 11b, at it and form above-mentioned groove 10 here between the chimb 11b.Do not peel off in order when the steel plate that sprays paint turns back, not make coating, above-mentioned front flange 11B is converted into interval P gentlely, and this gentle fold back portion is just just passable at the entrance side of groove 10, in fact, in the inside of groove 10, front chimb 11a and the inside chimb 11b are overlapping.The thickness Q of lap is equivalent to the thickness (with reference to Fig. 7) of two steel plates.

Front at the back flange 11A at the position, the corresponding upper front end turning of the dogleg section with end face and side of outer container body 7A is provided with the enhancing accessory (" L " shape reinforcement plate) 8 that the front is " L " font.Inboard at the back flange 11A of outer container body 7A is equipped with the enhancing accessory 30 that section is " コ " font, strengthen accessory 30 and cross over above-mentioned next door 32 and space before member 35,46 parts that disposed (forming the part of the vertical slit 29 of aftermentioned), extend along the vertical direction.

Like this, because an enhancing accessory 30 that extends along the vertical direction is installed in configuration next door 32 and space before member 35,46 parts that disposed, and be designed to stay up and down apart from a plurality of separated portions of ground leap, thereby just can strengthen being subjected to easily the part of several derivation " U " font part 5B of load effect with an accessory 30, needn't be as before, used respectively by the part of load effect at each and strengthen accessory or hingen pressing plate and hingen pressing plate installing plate, thereby number reduces when making number of components and assembler, has reduced assembly cost.

It is in order to prevent outer container 7 opening edge portion dewfall that refrigerant pipe 5 is provided in the above-mentioned groove 10, material manufacturings such as refrigerant pipe 5 usefulness copper or aluminium, the HTHP gaseous refrigerant that the compressor 42 that is provided with from the Machine Room 41 of body of thermal insulating box 1 bottom is sent is in pipe 5 internal flows.Gaseous refrigerant release heat and be condensed into liquid cryogen in the flow process of refrigerant pipe 5 inside is transported to cooler 38 again.

Below, be that the pipeline of a refrigerant pipe 5 is installed example.After pipe 5 is drawn from compressor 42, be suitably configured in Machine Room 41, a side of 41 (being from the left side in an embodiment) sets towards opening edge one side gradually along the side (left surface) of outer container body 7A from the Machine Room then, then groove 10 lower ends from outer container body 7A enter 10 li of grooves, set along groove 10.From the left surface to the end face, extend in order to the middle part (part in configuration next door 32) of right flank again and be provided with; Herein, pipe stretches out from groove 10, be provided in the previous section (this part is " U " font part 5B) in next door 32, get back to 10 li of grooves then again, be set to the part that space before member 46,35 disposes downwards along groove 10, from groove 10, stretch out again, be provided in the previous section (this part also is " U " font part 5B) of space before member 46,35, after this get back to 10 li of grooves again, along groove 10 down to lower end (representing to be configured in part in the groove 10) with 5A.After this, stretch out from the lower end of groove 10, set towards the rear gradually along the right flank of outer container body 7A, after this 41 right-hand member is got back to Machine Room 41 from the Machine Room, figure goes up the decompressor that does not have expression by capillary etc., is connected on the set cooler 38 in refrigerating chamber 33 backs.

The position that next door 32, space before member 35,46 are being set on the surface of interior case 9 forms groove 9A and the groove (there be not expression among the figure) that fully extends along fore-and-aft direction along depth respectively.In the 32 both ends insertion groove 9A of next door and be supported.And for " U " font part 5B of refrigerant pipe 5 that flange 13 is formed previously draws, groove 9A constitutes and becomes " コ " font recess 19 that roughly is of two sections steps to link to each other with depth direction.

In the present embodiment, next door 32 is split type with interior case 9, just need on interior case 9 groove 9A be set under the situation of next door 32 and interior case 9 formation one.The front side of next door 32 and space before member 35,46 is installed respectively with next door 32 or space before member 35,46 " U " font part 5B is clipped in wherein metal interval panel 15.

At interval panel 15 comprises with the joining part 150 of above-mentioned same installation hingen 23 and is arranged on the step part 151 that these two ends, joining part 150 left and right sides are used for inserting groove 10, and the thickness of slab of its thickness ratio outer container 7 is also thick.When inserting groove 10, joining part 150 is concordant with the front flange 11B of outer container body 7A, constitutes the abutted surface of above-mentioned door gasket; On the other hand, form the rib 154 that extends back, be used for keeping at interval and gain in strength at the upper and lower side of joining part 150; The upper and lower side of step part 151 also form with the rib 154 of joining part 150 continuously and the rib 153 of the enhancing usefulness that extends back.

The height of rib 154 can suitably be determined according to the shape of space before member 35,46.The height of rib 153 is then according to definite with the relation of the depth of groove 10 (i.e. the interval of back flange 11A and front flange 11B), both by comparison, aspect ratio rib 153 height of rib 154.

The step dimension R of step part 151 is identical or big slightly with the interval P of front flange 11B bending part; Bending forms step backward at the two ends of joining part 150, and turning forward gradually to the position of decline step dimension R from joining part 150 curves acute angle.When 10 li of grooves that step part 151 is installed to outer container 7, for the front end that makes step part 151 can contact with the inside chimb 11b, depth size till from the position of decline size R to step part 151 front ends is taken as S, should satisfies the relation (with reference to Fig. 7) of R-S≤Q.

Adopt the interval panel 15 of this spline structure, owing to be contained in step part 151 upper and lower sides of interval panel 15 of 10 li of the grooves of outer container 7 rib 153 is arranged, thereby the intensity of step part 151 is increased, step part 151 is out of shape because of the external force effect with regard to being difficult for.Again since at interval the step part 151 of panel 15 tilt gradually to the front, the inside chimb 11b of front end and outer container 7 joins, thereby it is very close to each other between the front end of the front flange 11B of outer container 7 and step part 151, the thin front flange 11B (its rear side) of thickness of slab is strengthened by the thicker step part 151 of thickness of slab, and front flange 11B just is difficult for depression backward.

Especially 153 in rib owing to step part 151 is arranged on upper and lower side, thereby shown in the arrow among Figure 11, when step part 151 is inserted into groove 10, does not contact " U " font part 5B; On the contrary, rib 153 joins with the first step of interior case 9 recesses 19 both sides, makes between the base of panel 15 and recess 19 at interval to keep the interval.Like this, before just solving when step part inserts by " U " font part 5B with interior case 9 after pressure be out of shape, and problem such as generation be full of cracks on interior case 9 thus also can be carried out the insertion operation of interval panel 15 smoothly.

Here, because interior case 9 is tabular components, so make its back side form protuberance 21 by recess 19.This protuberance 21 that roughly is " コ " word shape is inserted into 10 li of grooves.The corresponding part in protuberance 21 insertion positions with interior case 9 on the back flange 11A of outer container 7 is provided with the vertical slit 29 that extends along longitudinally (being above-below direction).

Along with the insertion of raised part 21, when back flange 11A was squeezed, this vertical slit 29 was just naturally and understandably squeezed wide, makes back flange 11A easy deformation.The length of vertical slit 29 and width can be determined only size according to the height and the rigidity of the protuberance 21 of the iron plate thickness that constitutes outer container 7 and rigidity, interior case 9.Set the optimum size of vertical slit 29, can avoid back flange 11A to be deformed to unnecessary degree, and interior case 9 inserts easily.

When the refrigerator of assembling said structure, earlier refrigerant pipe 5 is arranged on outer container body 7A and goes up groove 10 inside that form.As above said, this refrigerant pipe 5 is derived in the vertical slit 29 set directions of part to next door 32, carries out returning 10 li of grooves after " U " font is turned, and constitutes " U " font part 5B (with reference to Fig. 5).

Then, 5B bends towards hand the place ahead to (promptly leaving the direction in next door 32) temporarily " U " font part, and the outward flange 13 of interior case 9 is inserted into 10 li of grooves.When inserting, the protuberance 21 of interior case 9 is pressed to the inside with the back flange 11A of outer container 7.That is, in the part that protuberance 21 is inserted into, groove 10 is enough big space not, and therefore back flange 11A is subjected to protuberance 21 extruding.In the present embodiment, be extruded out because squeezing action is indulged slit 29, thereby make back flange 11A easily along direction of extrusion distortion, this distortion takes place along protuberance 21, roughly is " コ " font.

Then, respectively next door 32 and space before member 35,46 are installed on the assigned position.Then, 32 front is returned to original state (promptly becoming parastate with the opening edge portion of outer container 7) along the next door " U " font part 5B that is bending temporarily, after this interval panel 15 is configured to the front of " U " font part 5B, simultaneously the two ends (being step part 151) of interval panel 15 is inserted into 10 li of grooves as mentioned above.

Its result because the outward flange 13 of interior case 9 sandwiched by step part 151 and back flange 11A, thereby is subjected to a certain degree fastening force, and meanwhile, the step part 151 of panel 15 is sandwiched by front flange 11B and outward flange 13 and is subjected to fastening at interval.With two Screws (about each) two ends (step part 151) of the interval panel 15 that inserts are fixed on the front flange 11B of groove 10.

After the foaming end of job, during the same hingen 23 (with reference to Fig. 9) of fixing and Figure 15, the front flange 11B of outer container 7 is sandwiched with the step part 151 and the hingen 23 of hingen 23 1 sides, fix with a Screw again.Available same operating sequence is installed space before member 35,46.That is, space before member 35,46 is installed on the interior case 9,, refills panel 15 at interval the arranged in front of " U " font part 5B along space before member 35,46.

After this, the backplate 7B of outer container 7 and bottom panel 7C are assembled on the outer container body 7A, make backplate 7B be in the upside of foaming mould (not having expression among the figure).The inlet that forms from backplate 7B is filled into foamed thermal insulating 31 in the space that forms between outer container 7 and the interior case 9, and when foamed thermal insulating 31 sclerosis, panel 15 just is subjected to abundant supporting at interval.After the foaming end of job, hingen 23 is installed on the panel 15 of interval (with reference to Fig. 9) with bolt etc.

From above-mentioned explanation as can be known,, can obtain various effects, for example,, thereby need not form unnecessary big gap, can prevent that heat-insulating material 31 from spilling from the gap owing to the distortion of flange 11A afterwards takes place along protuberance 21 by above-mentioned structure.In addition, the flange 13 of interior case 9 is at the back flange 11A of its protuberance 21 extruding outer containers 7, rabbets 10 li of grooves when making back flange 11A distortion.After the interlocking, fastening by power to a certain degree, outer container 7 and interior case 9 are fixed temporarily, therefore, the work that makes filling with foam insulation materials 31 in the subsequent handling is just than carrying out easily in the past.

Because such big otch 17 (with reference to Figure 14) not being provided with on the groove 10 before, thereby the problem that reduces significantly with regard to the intensity that can not form by 17 generations of this otch.And the heat-insulating material 31 that is filled between outer container 7 and the interior case 9 has sufficient rigidity after sclerosis, makes casing have higher intensity.Also can draw thus,, also have full intensity to support hingen 23 (with reference to Fig. 9) etc. even former hingen pressing plate 27 and hingen pressing plate installing plate 25 (with reference to former illustration 14) are removed.

Like this, in the present invention, because the step part of panel forwards tilts gradually at interval, the inside chimb of front end and outer container joins, thereby the front flange of outer container and the gap between the step part are eliminated, the rear side of front flange is strengthened by step part, at fixing hingen or when the fixed components such as screw thread used of panel are fastening at interval, just can prevent that front flange from caving in to rear side.

Again because the step part upper and lower side that is contained in the interval panel in the outer container groove is being provided with the rib that strengthens usefulness, thereby can prevents the crooked of the step part that causes by the hingen applied force of installing on the panel of interval for the intensity that strengthens step part or be out of shape.

In addition, for sky is opened certain distance, cross over several different pieces configuration next door and space before member up and down, the enhancing accessory that extends along the vertical direction is installed, thereby just can strengthen the several different pieces that are subjected to load easily of above-mentioned outer container with an accessory, do not need hingen pressing plate and hingen pressing plate installing plate, can reduce the part number, reduce the manufacturing cost and the assembly cost of part.
