The side below holding container 6b in lower floor is provided with moisture absorption discharging gear release mechanism 62, and this moisture absorption discharging gear release mechanism 62 holds air from the outside of container 6b to lower floor releases the moisture produced from the greengrocery of the inside being contained in lower floor accommodation container 6b.

Moisture absorption discharging gear release mechanism 62 is provided with: the high thermal conductivity parts 63 of the such as aluminum that the thermal conductivity be cooled from the outside of lower floor accommodation container 6b is higher; And than high thermal conductivity parts 63 (with reference to Fig. 6) rearward side, face bottom is contacted with high thermal conductivity parts 63 and sheet form the higher such as fiber of water imbibition water suction release parts 64 (reference Fig. 6).

The moisture that the vegetables held in container 6b from lower floor produce high thermal conductivity parts 63 surface cool and condense and become water droplet, being released parts 64 by water suction absorbs, thus water suction to release parts 64 moistening because of capillarity phenomenon.The moisture that water suction is released contained by parts 64 contacts with the air of the low temperature flowed between interior case 10a with the container (lower floor holds container 6b, upper strata holds container 6c) in vegetable compartment 6, releases in the air of this low temperature.

As shown in Figure 9, lower floor hold container 6b be placed with above possess bottom surface, above, below, the upper strata accommodation container 6c of left surface and right flank.Upper strata accommodation container 6c probably configures suitable gap 65 in the inner side of lower floor accommodation container 6b and is fitted together to.Upper strata holds before container 6c, below, the limit of the upside of left surface and right flank becomes the flange part 66 that toward the outer side and with having thickness turns back to obtain rigidity.

The periphery of flange part 66 becomes the mounting portion 67 of stretching out further downwards, the flange part 68 turned back laterally in upper end mounting portion 67 being placed in the wall of left and right sides lower floor being held container 6b, can move along the longitudinal direction in the scope of regulation.Fig. 6, Fig. 7 and Figure 10 are the states that upper strata accommodation container 6c configures near front relative to lower floor accommodation container 6b, and in this situation, vegetable compartment 6 is the states of closing relative to refrigerator main body 1H.If the upper strata of the state of pull-out holds container 6c and is pressed towards vegetable compartment 6 side in vegetable compartment 6, then by be formed at concave shape formed vegetable compartment 6 internal face in the pull out guide rail of case 10a support.In addition, under the state that vegetable compartment door 6a closes, upper strata holds container 6c is held container 6b upper edge support by lower floor.

As shown in Figure 6, hold the side holding container 6b close to lower floor of the bottom surface of container 6c on upper strata, the limit holding the rear side of container 6b along lower floor is provided with the liner 69 of such as soft rubber.When vegetable compartment 6 is closed, liner 69 holds the location contacts on the limit of the rear side of container 6b with forming lower floor, closes the position forming lower floor and hold the limit of the rear side of container 6b.

As shown in Figure 7, when vegetable compartment 6 is closed, the what is called that the protuberance 71 of the mounting portion 67 (with reference to Fig. 9) of the recess 70 being located at the left and right sides upper end of lower floor accommodation container 6b and the left and right sides being located at upper strata accommodation container 6c is mutually chimeric falls into locate.

At this, recess 70 falls into obtained Qian He built on the sand with protuberance 71.In other words, if hold container 6c from front to upper strata to apply the above power of regulation, then protuberance 71 departs from from recess 70, thus upper strata hold container 6c become hold container 6b relative to lower floor can the structure of rearward movement.

As shown in Figure 6, be following structure, the first abutting part 72 that the rear portion namely, on upper strata holding container 6c is arranged towards rear and abutting at the second abutting part 73 that adiabatic partition wall 11b is arranged toward the front, thus restriction upper strata accommodation container 6c rearward moves.In addition, if hold the structure of container 6c rearward movement on restriction upper strata, assigned position, then the structure that the second abutting part 73 is set at adiabatic partition wall 11b is not necessarily defined as.

The central front portion holding container 6c on upper strata is provided with bolt lock mechanism 80, and this bolt lock mechanism 80 pairs of vegetable compartment separators 74 and upper strata hold between container 6c and lock, and can be unlocked by lever operated, but its detailed construction aftermentioned.

As shown in the top view of Figure 10, the face that the face in the front of bolt lock mechanism 80 is configured to hold with upper strata the front of container 6c is roughly the same face, or in the depth size of regulation.The anterior spatial accommodation 6b1 (with reference to Fig. 7) holding container 6b relative to lower floor due to bolt lock mechanism 80 does not stretch out significantly, thus when producing obstruction when accommodation recess 61 drinks etc.

As shown in Figure 6, with become bottom surface that lower floor holds container 6b with hold recess 61 border step 60 close to and exceed the face of step 60 1 side, separate the vegetable compartment separator 74 that lower floor holds container 6b before and after being detachably provided with.When being provided with vegetable compartment separator 74, that lower floor is held container 6b is divided into anterior spatial accommodation 6b1 on the front than vegetable compartment separator 74, to be divided into rear portion spatial accommodation 6b2 rearward than vegetable compartment separator 74, when taking off vegetable compartment separator 74, lower floor holds container 6b entirety becomes a spatial accommodation.

Because vegetable compartment separator 74 is configured to be placed in the face be located at lower floor and held the higher side of the step 60 of the bottom surface of container 6b, so the height of vegetable compartment separator 74 only holds the height of the bottom surface of container 6c from the face of the higher side of step 60 to upper strata, thus suppress the overall height of vegetable compartment separator 74 and miniaturized.

Vegetable compartment separator 74 configures in the mode on the limit holding the forward lower part of container 6c close to upper strata, and being provided with breech lock carrier 75 in the upper end of vegetable compartment separator 74, this breech lock carrier 75 locks (detailed construction will in hereinafter describe) for holding container 6c via bolt lock mechanism 80 to vegetable compartment separator 74 and upper strata.

< vegetable compartment separator 74 >

Then, the structure of Figure 11 to Figure 15 to vegetable compartment separator 74 is used to be described.

Figure 11 is the stereogram observing vegetable compartment separator 74 obliquely from the front, shortens province's sketch map of the length direction of left and right for local.And, the separation guide 76 being located at lower floor accommodation container 6b in order to load and unload vegetable compartment separator 74 is illustrated with the shape of only taking out its part to illustrate, and is expressed as the exploded perspective view of the position relationship of vegetable compartment separator 74 and separation guide 76.

Figure 12 is the F-F sectional view of Figure 11, represents the profile construction of vegetable compartment separator 74.

Figure 13 is the stereogram observing vegetable compartment separator 74 from oblique rear, is expressed as province's sketch map that local shortens the long side direction of left and right identically with Figure 11, and, illustrate the structure that lower floor holds container 6b and separates guide 76 partly.

Figure 14 represents that vegetable compartment separator 74 and lower floor hold the top view of the configuration of container 6b.

Figure 15 be represent vegetable compartment separator 74 and lower floor hold the relation of container 6b, the G-G sectional view of Figure 13.

As shown in Figure 11 to Figure 13, vegetable compartment separator 74 is such as be formed as combining the structure having resinous spacing frame 74b around the glass plate 74a of quadrangle integratedly.Because glass plate 74a is transparent, so when visualization the food in lower floor accommodation container 6b can be contained in by vegetable compartment separator 74 after opening vegetable compartment 6, easily confirm saturation, the state of food.

As shown in figure 12, the bottom along vegetable compartment separator 74 is provided with the holding groove 74c as recess, on the other hand, holds the position corresponding with holding groove 74c of container 6b in lower floor, is provided with the bottom surface protuberance 77 (with reference to Figure 13) as projection upwards.Bottom surface protuberance 77 and holding groove 74c have the effect being arranged at by vegetable compartment separator 74 and positioning when lower floor holds container 6b.In addition, holding groove 74c and bottom surface protuberance 77 become mutually chimeric and group enters so-called maze configuration, so there is the effect of the movement of the gas hindered between anterior spatial accommodation 6b1 (with reference to Figure 15) and the rear portion spatial accommodation 6b2 putting into vegetables.

Be provided with breech lock carrier 75 in the top center portion of vegetable compartment separator 74, this breech lock carrier 75 is for mutually locking via the breech lock 83 (with reference to Figure 12) being located at bolt lock mechanism 80 (with reference to Figure 10) vegetable compartment separator 74 and upper strata accommodation container 6c and unlock.

Upper strata holds the breech lock 83 (with reference to Fig. 8) of container 6c and that lock position chimeric with the breech lock carrier 75 (with reference to Fig. 8) of vegetable compartment separator 74 to be become upper strata and holds container 6c and hold the chimeric position of container 6b because of recess 70 (reference Fig. 7) and falling into of protuberance 71 with lower floor.Therefore, when upper strata accommodation container 6c is locked, it is chimeric because falling in left and right sides that upper strata accommodation container 6c and lower floor hold container 6b, and, central portion is locked by bolt lock mechanism 80 and vegetable compartment separator 74, thus reliably carries out the location of upper strata accommodation container 6c.

As shown in figure 13, vegetable compartment separator 74 inserts along the separation guide 76 being located at lower floor accommodation container 6b, and is installed on lower floor accommodation container 6b.At this, the below of the left and right sides of vegetable compartment separator 74 and rear side form the recess 74d of removing crestal line.Be located at lower floor to hold in the separation guide 76 of container 6b, be provided with protuberance 76b in the position that the recess 74d with vegetable compartment separator 74 is corresponding, avoid the interference of recess 74d and protuberance 76b.

On the other hand, when making all around of vegetable compartment separator 74 or oppositely inserting separation guide 76 up and down, interfere owing to separating the protuberance 76b of the guide 76 and spacing frame 74b of vegetable compartment separator 74, so vegetable compartment separator 74 cannot be arranged on along separation guide 76 position of regulation.Therefore, when to get wrong vegetable compartment separator 74 towards and settle, user can easily identification error.

Therefore, vegetable compartment separator 74 correctly holds container 6b with what specify towards being placed in lower floor relative to all directions of top to bottom, left and right, front and rear, can not towards oppositely settling.Namely, according to above-mentioned structure, the effect that the breech lock carrier 75 with vegetable compartment separator 74 is reliably installed along correct direction.

Figure 16 is the exploded perspective view of the structure representing vegetable compartment 6.

At the two ends, left and right of vegetable compartment door 6a, and be provided with backing roll 58 at the supporting guide 55 outstanding towards rear.Backing roll 58 can be slidably inserted into the main body guide rail 59 (with reference to Fig. 7) being located at case 10a in refrigerator main body 1H along the longitudinal direction.Further, be configured to, by loading supporting guide 55 at main body roller 56, thus vegetable compartment door 6a can move and opening and closing along the longitudinal direction.Load lower floor at the supporting guide 55 of left and right and hold container 6b.Further, be configured to, vegetable compartment separator 74 is settled along the separation guide 76 (with reference to Figure 15) being located at lower floor accommodation container 6b from top with inserting downward, and upper strata accommodation container 6c is placed in lower floor accommodation container 6b.

As mentioned above, if vegetable compartment separator 74 is placed in lower floor to hold container 6b, then lower floor's accommodation container 6b is divided into anterior spatial accommodation 6b1 and rear portion spatial accommodation 6b2 (with reference to Fig. 7) by vegetable compartment separator 74.Herein, be the space for preserving the tall and big food such as beverage of such as putting into bottle or container than vegetable compartment separator 74 anterior spatial accommodation 6b1 on the front, and become the region of the space open in inside case 10a.Namely, the cold air in vegetable compartment 6 freely comes and goes at anterior spatial accommodation 6b1.

On the other hand, spatial accommodation 6b2 in rear portion is held container 6c when vegetable compartment 6 is closed by vegetable compartment separator 74 and upper strata and is configured to close to airtight suitable airtight conditions.

Namely, be configured to, held the maze configuration separation of the bottom surface protuberance 77 of container 6b and the holding groove 74c of vegetable compartment separator 74 below vegetable compartment separator 74 by lower floor, and the left and right side of vegetable compartment separator 74 is embedded in the groove separating guide 76, thus hinders passing through of gas.

Being located at local below that liner 69 (with reference to Fig. 6) that upper strata holds the width below container 6c contact of rear portion spatial accommodation 6b2 and local is airtight, thus prevent the rear portion spatial accommodation 6b2 of the cold air inflow lower floor accommodation container 6b discharged from blow-off outlet 25a (with reference to Fig. 4).

On the other hand, lower floor holds via the upper strata be located at shown in Fig. 9, the side of container about 6b and bottom rear two ends hold that container 6c and lower floor hold gap 65 between container 6b and to hold container 6c chimeric with upper strata, and the cold air of discharging from the inside of blow-off outlet 6c inside case 10a passes through gap 65 and with in the rear portion spatial accommodation 6b2 of trace inflow lower floor accommodation container 6b.Like this, by making rear portion spatial accommodation 6b2 be hemiclosed structure, thus greengrocery, fruit thing class etc. that restriction is accommodated in the spatial accommodation 6b2 of rear portion are exposed in cold air, suppress the drying such as greengrocery, fruit thing class, can keep freshness.

Herein, as an example of the size in gap 65 (with reference to Fig. 9), be about 2mm to 3mm.If this gap 65 is excessive, then too flow into lower floor from the cold air of blow-off outlet 25a (with reference to Fig. 4) and hold greengrocery, fruit thing class etc. in container 6b, thus produce the problem points that lower floor's humidity held in container 6b reduces and vegetable drying, freshness decline and so on.On the other hand, if gap 65 is too small, then the air in rear portion spatial accommodation 6b2 is not stirred, thus produces that lower floor's Temperature Distribution held in container 6b becomes large and temperature local reduces, a part for wall easily generates the problem points of condensation.

Therefore, preferably keep the cold air of only trace to flow into suitable gap such in the spatial accommodation 6b2 of rear portion, and become close to closed state and the airtight conditions of the appropriateness obtained by greengrocery, fruit thing class etc.

Because rear portion spatial accommodation 6b2 becomes the airtight conditions of the appropriateness close to air-tight state, can be described as semi-closed state, thus in the spatial accommodation 6b2 of rear portion the moisture that produced by held greengrocery etc. and be maintained humidity close to 100% high humidity state.And, the outside holding container 6b by moisture absorption discharging gear release mechanism 62 (with reference to Fig. 6) to lower floor due to the excessive moisture condensed at wall releases, so maintain the freshness of vegetables etc. and dew can not be attached to wall, the bottom surface that lower floor holds container 6b as water droplet, thus there is the effect of the freshness maintaining greengrocery etc.

< bolt lock mechanism 80 >

Next, Figure 17 to Figure 19 is used to be described the structure being located at upper strata and holding the bolt lock mechanism 80 in the central front portion of container 6c.

Figure 17 (a) is the stereogram from oblique forward observation bolt lock mechanism 80, and Figure 17 (b) is the stereogram from observation bolt lock mechanism 80 in rear tiltedly.

Figure 18 (a) ~ (c) is the stereogram representing order bolt lock mechanism 80 being installed on upper strata accommodation container 6c.

Figure 19 is the G-G sectional view of Figure 18 (c).

As shown in figure 17, bolt lock mechanism 80 has: the breech lock housing 81 forming profile; And before the central portion of bolt lock mechanism 80, above and a part below for the handle 82 of user's operation.User is when removing upper strata and holding the locking of container 6c (with reference to Figure 16) and vegetable compartment separator 74 (with reference to Figure 16), and arrow α 1 direction to Figure 17 presses.

As shown in Figure 21 (a) ~ (c), breech lock 83 can engage relative to the breech lock carrier 75 of the upper-center being located at vegetable compartment separator 74, arrange discretely.Breech lock 83 lower end towards rearward face roughly vertical, face be toward the front formed as more below more towards rearward R shape.

As shown in Figure 21 (c), breech lock 83 is moved by upward direction and removes the engaging with the breech lock carrier 75 of the upper-center being located at vegetable compartment separator 74, thus removes the locking of upper strata accommodation container 6c and vegetable compartment separator 74.

On the other hand, as shown in Figure 21 (a), breech lock 83 is by downward direction moving and engaging with the breech lock carrier 75 of the upper-center being located at vegetable compartment separator 74, thus upper strata holds container 6c and vegetable compartment separator 74 locks.

At this, the second arm 98 and latch arms 99 be arranged on by breech lock housing 81 around space in than handle 82 scope in the outer part, be configured to, even if handle 82 rotates, handle 82, second arm 98 and latch arms 99 are not also interfered.

In addition, relative to the latch arms fulcrum 100 being subject to the power from bellcrank 93 via the second arm 98, breech lock 83 is configured at roughly below projected position.Therefore, the power that latch arms 99 is subject to from the second arm 98 is consistent with the direction that breech lock 83 rises and do not produce bending moment, thus has breech lock 83 and do not tilt and the effect of the having stable behavior of breech lock 83.

Under the state that breech lock 83 coordinates with breech lock carrier 75, be located at lower floor shown in Figure 16 hold the recess 70 of the upper end in the left and right sides portion of container 6b and be located at the protuberance 71 that upper strata holds the mounting portion 67 of the left and right sides of container 6c and be mutually fitted together to, and become and fall into the structure of locating by what is called.That is, the Qian He be configured to, lower floor holds container that container 6b and upper strata hold container 6c concavo-convex the obtained nested position fallen into each other, obtaining with breech lock 83 and the breech lock carrier 75 of being located at vegetable compartment separator 74 produces simultaneously.

The imparting > of the latch-release sense of < breech lock 83 and breech lock carrier 75

This refrigerator 1 possesses following structure, namely, to user gives breech lock 83 and is located at the locking of breech lock carrier 75 of vegetable compartment separator 74 by the operation sense removed.

As shown in Figure 21 (a) ~ (c) of the Figure 20 (a) of the stereogram from forward observation, (b) and sectional view, stretch out the plate spring part 103 arranging and abut (contact) and the softness of elastic deformation with the back side 82b of handle 82 from bellcrank axle 94.

Plate spring part 103 has: elastic deformation and give the arm 103a of elastic force; And be located at the front end of arm 103a and abut the leading section 103b of (contact) with the back side 82b of handle 82.

Arm 103a can for such as having the shape in rectangular-shaped cross section, if but the elastic force that specifies can be obtained, its shape is arbitrary.

Leading section 103b can be the drum such as in the lateral direction with axle, if but the function specified can be played, its shape is arbitrary.In addition, leading section 103b is when the position abutted with the back side 82b of handle 82 has curvature, and its action or slip can become smooth and easy, thus more desirable.

The back side 82b of handle 82 has: the plane domain 82b1 of bottom; And there is at left and right directions (direction, the table back side of the paper of Figure 21) the curved surface area 82b2 on the top of axle.Therefore, the recess 82b3 of the wire that the state having face between the plane domain 82b1 and the curved surface area 82b2 on top of bottom changes.In addition, in this example, the region illustrating top is curved surface area 82b2, the region of bottom is the situation of plane domain 82b1, but 82b overleaf, if the surface state of upper and lower changes at recess 82b3, then the face on top and the face of bottom can be arbitrary face.

The elastic force that plate spring part 103 is produced by the elastic deformation of arm 103a and leading section 103b with the crimp force of appropriateness be located at plane domain 82b1, the curved surface area 82b2 of back side 82b of handle 82, recess 82b3 abuts.

As an example, if by the shaping bellcrank axle 94 of polyacetal resin, then the first arm 96, second arm 98, plate spring part 103 also can be integrated with bellcrank axle 94.

The action > of < bolt lock mechanism 80

Then, the action of bolt lock mechanism 80 is described.

Figure 20 (a) and Figure 21 (a) represents non-operating grip 82, the state that breech lock 83 engages with the breech lock carrier 75 of the upper-center of vegetable compartment separator 74.

Situation shown in Figure 20 (a), Figure 21 (a) is that breech lock 83 is compressed spring 101 and is in for the active force of the prolonging direction of the shape that resiles the position moving to bottom.Namely, breech lock 83 is in outstanding state downwards.

Breech lock 83 is in the position of decline, and the lower end of breech lock 83 engages with the breech lock carrier 75 being located at vegetable compartment separator 74 upper end, becomes upper strata and holds the container 6c state relative to the vegetable compartment separator 74 not locking of rearward movement.In this condition, vegetable compartment separator 74 is comprised and the lower floor that formed holds and holds container 6c by upper strata in container 6b and become semi-closed state.

Because latch arms fulcrum 100 is afterburning downward, so in figure 21, bellcrank 93 is rotated counterclockwise by reinforcing.Therefore the recess 82b3 on the plane domain 82b1 of bottom and the border of the curved surface area 82b2 on top of leading section 103b to the back side 82b being positioned at handle 82 of plate spring part 103 is afterburning and crimp, and handle 82 to be in by reinforcing the state that (arrow α 2 direction of Figure 20 (a), Figure 21 (a)) counterclockwise rotates.

In addition, in this situation, the first arm 96 does not contact with the arm press section 97 of the 82b side, the back side of handle 82.As mentioned above, first arm 96 contacts with the arm press section 97 of the 82b side, the back side of handle 82 and refers to, user presses the handle 82 shown in Figure 21 (c) to arrow α 1 direction, removes the engaging of the breech lock 83 of handle 82 and the breech lock carrier 75 of vegetable compartment separator 74 and situation about unlocking.

Near the contact site of the leading section 103b of the plate spring part 103 of the recess 82b3 of the back side 82b of handle 82, apply the lubricant g such as lubricating grease (with reference to Figure 21), thus the contact of the leading section 103b of the back side 82b of handle 82 and plate spring part 103 becomes smooth and easy.In addition, as the function that lubricant g plays regulation, then also can be the lubricant g beyond lubricating grease, also can not make with lubricator g.

And, if user rearward presses handle 82 (arrow α 1 direction of Figure 20 (a), Figure 21 (a)) to open lower floor accommodation container 6b, then the thorny handle fulcrum 92 of handle 82 rotates to the clockwise direction of Figure 20 (a), Figure 21 (a).So, the leading section 103b of plate spring part 103 is subject to the rearward power of recess 82b3 of the back side 82b from handle 82, the arm 103a of plate spring part 103, as shown in Figure 21 (b), is positioned at the mode elastic deformation at rear with leading section 103b around bellcrank fulcrum 95.

In this situation, along with arrow α 1 direction of the thorny handle fulcrum 92 of handle 82 to Figure 21 (a), Figure 21 (b) is rotated, the quantitative change of the elastic deformation of arm 103a is large.Now, the elastic force of the elastic deformation of arm 103a is utilized to make handle 82 become large gradually around the power of the counter clockwise direction pressing centered by handle fulcrum 92.Now, as resistance, user can be subject to the anticlockwise power of handle 82.

Further, if the thorny handle fulcrum 92 of handle 82 rotates to arrow α 1 direction of Figure 21 (b), then the amount of the elastic deformation of arm 103a increases significantly, and the amount of the elastic deformation of arm 103a reaches capacity.So as shown in Figure 21 (c), the leading section 103b of plate spring part 103 departs from from recess 82b3, resets into the original shape close to arm 103a, and contacts with the curved surface area 82b2 on the top of the back side 82b of handle 82.Now, bellcrank 93 rotates clockwise around bellcrank fulcrum 95, second arm 98 rotates clockwise to diagram, and the breech lock 83 linked with the second arm 98 rises upward, thus the engaging of the releasing breech lock 83 of handle 82 and the breech lock carrier 75 of vegetable compartment separator 74.

Meanwhile, the elastic force of arm 103a reduces suddenly and the anticlockwise resistance of handle 82 reduces suddenly, and therefore user can experience the click effect of latch-release.

At this, the rotating shaft of handle 82 is different respectively from the rotating shaft of plate spring part 103, thus the rotational trajectory of handle 82 is different respectively from the rotational trajectory of plate spring part 103.Therefore, if handle 82 rotates, then arm 103a has and contacts and the interval of elastic deformation with handle 82 back side 82b.Then, along with the rotation of handle 82, plate spring part 103 is also rotated further, thus the contact condition of arm 103a to the back side 82b of handle 82 changes, thus arm 103a has the interval of removing from elastic deformation.

In addition, the shape of handle 82 is not limited to 82b overleaf and has curved surface area 82b2, if the rotating shaft of handle 82 is different respectively from the rotating shaft of plate spring part 103, the rotational trajectory of handle 82 is different respectively from the rotational trajectory of plate spring part 103, even if then also can obtain identical effect in the plane.

Click effect refers to, such as when operating grip 82, give following characteristic, namely the initial load (elastic force of plate spring part 103), from static state during action is larger, on the other hand from load (elastic force of plate spring part 103) is sharply reduced after action, thus the action of handle 82 can be passed on clearly to the releasing action of breech lock 83 to the sense of touch of user.

If arrange, then as shown in Figure 21 (a), when breech lock 83 is embedded in breech lock carrier 75 and becomes the state of locking, leading section 103b is chimeric with recess 82b3.If operator makes handle 82 move towards rear, make bellcrank axle 94 start to rotate, then plate spring part 103 elastic deformation and reaction force increase, thus the operating physical force of handle 82 (resistance) increases.

If make handle 82 rearward move further, then leading section 103b departs from from recess 82b3 and is moved upward, and as shown in Figure 21 (c), becomes the state abutted with the curved surface area 82b2 of the back side 82b of handle 82.In the moment that leading section 103b departs from from recess 82b3, the abutted position of leading section 103b sharply changes and reaction force reduces.Therefore, the operating physical force (resistance) of handle 82 sharply reduces, and can give so-called click effect.

Almost plate spring part 103 leading section 103b from recess 82b3 depart from while, bellcrank 93 around bellcrank fulcrum 95 identical with handle 82 rotate clockwise, the second arm 98 be integrally formed with bellcrank 93 also rotates clockwise.Because the second arm 98 rotates clockwise, so latch arms fulcrum 100 is moved upward, breech lock 83 is moved upward.The lower end of breech lock 83 is left upward from the breech lock carrier 75 being located at vegetable compartment separator 74 upper end and removes chimeric.Therefore, become upper strata hold container 6c rearward can the state of state, i.e. latch-release of movement relative to vegetable compartment separator 74.

Namely, owing to making handle 82 move towards rear in (arrow α 1 direction of Figure 20, Figure 21), the quantitative change of the elastic deformation of the arm 103a softness of plate spring part 103 is large, when the amount of elastic deformation reaches capacity, arm 103a resets to original shape, and the leading section 103b of plate spring part 103 contacts with the curved surface area 82b2 of the back side 82b of handle 82.Almost simultaneously, if the bellcrank 93 being formed with plate spring part 103 to rotate and the second arm 98 is moved upward clockwise around bellcrank fulcrum 95, then latch arms fulcrum 100 is moved upward, and rises with the breech lock 83 that latch arms fulcrum 100 links.Because breech lock 83 rises, the breech lock 83 as bolt lock mechanism 80 is removed with the locking of the breech lock carrier 75 of vegetable compartment separator 74.

At this, because breech lock 83 is located near before bolt lock mechanism 80, so less from the distance before vegetable compartment separator 74 to bolt lock mechanism 80.Namely, bolt lock mechanism 80 or upper strata hold container 6c and do not stretch out relative to the anterior spatial accommodation 6b1 of lower floor accommodation container 6b above, thus anteriorly spatial accommodation 6b1 can not be hindered to take out, put into food.

As shown in figure 20, in the breech lock housing 81 near about a pair second arm 98 of bellcrank 93 and the two ends, left and right being arranged on bellcrank axle 94 across handle 82 with about a pair latch arms 99 of breech lock 83 one that link with the second arm 98.Therefore, if operating grip 82 and make bellcrank 93 rotate, then latch arms 99 symmetery ground rises.Therefore, be located at integratedly latch arms 99 central authorities downside breech lock 83 not in the lateral direction or above-below direction tilt and roughly rise symmetery.Therefore, the having stable behavior of the above-below direction of breech lock 83, and there is latch-release and lock reliable effect.

The state that < upper strata accommodation container 6c rearward moves and opens is to the action > closed

Then, according to Figure 22, upper strata is held that container 6c rearward moves and the state opened is described to action when closing.

Figure 22 (a) represents the locking of releasing bolt lock mechanism 80 and makes upper strata accommodation container 6c rearward move thus produce the state of the opening 102 of rear portion spatial accommodation 6b2.Under this state, the breech lock 83 moved up and down does not contact with breech lock carrier 75, becomes mutually state freely.

The face toward the front of breech lock 83 lower end is configured to more below R shape 83r more rearward.On the other hand, the face towards rearward side of breech lock carrier 75 upper end forms the inclined plane 106 that more front is more outstanding.According to these structures, due to when closing upper strata and holding container 6c, the R shape 83r of breech lock 83 abuts with the inclined plane 106 of breech lock carrier 75, so as shown in Figure 22 (b), breech lock 83 overcomes boosting upward for the active force extended of Compress Spring 101, and the clockwise direction of bellcrank axle 94 via the second arm 98 to Figure 22 (a), (b) rotates.

If make upper strata hold container 6c from the state shown in Figure 22 (b) further forwards to move, then breech lock 83 is crossed breech lock carrier 75 and becomes the state of Figure 21 (a), and upper strata holds container 6c or bolt lock mechanism 80 returns the state locked relative to vegetable compartment separator 74.

In this process, the back side 82b due to handle 82 is in the state (with reference to Figure 22 (b)) be separated from the leading section 103b of plate spring part 103, so the existence of plate spring part 103 can not become the resistance moved up and down of breech lock 83.

< vegetable compartment separator 74 and lower floor hold the relation > of container 6b

Then, the relation that vegetable compartment separator 74 and lower floor hold container 6b is described.

Figure 24 is the K-K generalized section of the Figure 15 of the state be placed in ideally by vegetable compartment separator 74 in lower floor accommodation container 6b.Figure 25 (a) is that the lower floor be out of shape because of heat affecting when being shaped illustrated in an example of comparative example holds the base plate of container 6b and the relation of vegetable compartment separator 74, corresponding with the D-D section of Fig. 7 schematic diagram, and Figure 25 (b) is that the lower floor be out of shape because of heat affecting when being shaped illustrated in other example of comparative example holds the base plate of container 6b and the relation of vegetable compartment separator 74, corresponding with the D-D section of Fig. 7 schematic diagram.

Lower floor holds container 6b and it is desirable to as shown in figure 24, and the base plate 6bt that lower floor holds container 6b is formed as tabular surface (plane).Therefore, when vegetable compartment separator 74 is placed in lower floor accommodation container 6b, the lower edge 74t of vegetable compartment separator 74 is almost seamlessly connected to lower floor to be held between the base plate 6bt of container 6b, and is placed in the commitment positions in lower floor accommodation container 6b.

At this, there is following situation, that is, lower floor holds container 6b is resin forming product, the impact of heat during because being shaped, thus the base plate 6bt warpage that lower floor holds container 6b is configured as convex, or warpage is configured as concavity.

As shown in Figure 25 (a), when the base plate 6bt warpage that lower floor holds container 6b is configured as concavity, when vegetable compartment separator 74 is placed in lower floor accommodation container 6b, the base plate 6bt holding container 6b due to lower floor is concavity, so the commitment positions that the lower edge 74t of vegetable compartment separator 74 does not hinder the base plate 6bt of lower floor accommodation container 6b and is placed in lower floor accommodation container 6b.

On the other hand, as shown in Figure 25 (b), when the base plate 6bt warpage that lower floor holds container 6b is configured as convex, vegetable compartment separator 74 collides the convex form that lower floor holds the base plate 6bt of container 6b, and set position cannot be placed in, vegetable compartment separator 74 is positioned at than commitment positions by the top.

In this situation, produce following situation, namely, as shown in Figure 22 (a), (b), when the rear side toe lateral making upper strata accommodation container 6c from lower floor accommodation container 6b moves, upper strata holds container 6c and collides vegetable compartment separator 74, and is used in that upper strata holds that the breech lock 83 of container 6c is chimeric with the breech lock carrier 75 of vegetable compartment separator 74 and bolt lock mechanism 80 that is that lock can not move.

Figure 26 (a) is the K-K generalized section that the vegetable compartment separator 74 of an example of embodiment is placed in lower floor and holds Figure 15 of the state in container 6b, and Figure 26 (b) is the K-K generalized section that the vegetable compartment separator 74 of other example of embodiment is placed in lower floor and holds Figure 15 of the state in container 6b.

Therefore, in view of lower floor holds the impact of heat when container 6b is shaped, as shown in Figure 26 (a), the lower edge 74t1 of vegetable compartment separator 74 is positioned at the concave shape of top as center side along vertical in advance and is formed, and the base plate 6bt warpage becoming lower floor accommodation container 6b is configured as the relief portion of convex.

Like this, it is the shape of convex that the lower edge 74t1 of vegetable compartment separator 74 avoids the warpage that lower floor holds the central portion of the base plate 6bt of container 6b, even if thus when the base plate 6bt warpage that lower floor holds container 6b is configured as convex, vegetable compartment separator 74 also accurately can be placed in the assigned position that lower floor holds container 6b.Therefore, as shown in Figure 22 (a), (b), when the rear side toe lateral making upper strata accommodation container 6c from lower floor accommodation container 6b moves, upper strata holds container 6c can not collide vegetable compartment separator 74, can be used in that upper strata holds that the breech lock 83 of container 6c is chimeric with the breech lock carrier 75 of vegetable compartment separator 74 and bolt lock mechanism 80 that is that lock moves effectively.

In addition, if make the lower edge 74t of vegetable compartment separator 74 become center side along vertical be positioned at top concave shape, then except the curvilinear concave shape shown in Figure 26 (a), also can, as shown in Figure 26 (b), the lower edge 74t2 of vegetable compartment separator 74 be made to be with step-like concave shape.Namely, as long as if the mode of the shape that the lower edge 74t of vegetable compartment separator 74 is convex with the warpage of the central portion can avoiding the base plate 6bt of lower floor accommodation container 6b becomes concave shape, then its shape also can be the shape beyond the shape shown in Figure 26 (a), (b), is arbitrary shape.

At this, even if preferred lower edge 74t1,74t2 at vegetable compartment separator 74 (with reference to Figure 26 (a), (b)) are for also arranging bottom surface protuberance 77 when concave shape, this bottom surface protuberance 77 enters the holding groove 74c as recess of the formation of the lower edge 74t along vegetable compartment separator 74 shown in above-mentioned Figure 13 using the maze configuration being formed at lower floor accommodation container 6b with being fitted together to, and suppresses cold air to hold in container 6b to lower floor thus and comes in and goes out.

According to the present embodiment, when user to open be placed in the lower floor upper strata held on container 6b hold container 6c and to arrow α 1 direction pressing handle 82 of Figure 20, be formed at the leading section 103b of the plate spring part 103 of bellcrank 93 to abut (contact) with the recess 82b3 of the back side 82b of handle 82, the arm 103a elastic deformation of plate spring part 103 and giving and resistance sense user.

And, as shown in Figure 21 (c), when breech lock 83 upward direction of bolt lock mechanism 80 moves and departs from the engaging that vegetables are located at the breech lock carrier 75 of the upper-center of dish room separator 74 and unlock, the leading section 103b of plate spring part 103 to depart from and the amount of the elastic deformation of the arm 103a of plate spring part 103 reduces suddenly from the recess 82b3 of the back side 82b of handle 82.Therefore, the resistance sense giving user from handle 82 reduces suddenly, can give the operation sense of latch-release.Therefore, user has operation sense and can carry out the use of refrigerator giocoso.

In other words, bolt lock mechanism 80 extends the plate spring part 103 being provided with softness from bellcrank axle 94 towards handle 82, using the front end of plate spring part 103 as such as cylindric leading section 103b, utilize the elastic deformation of plate spring part 103 to abut with the recess 82b3 of the crimp force of appropriateness with the back side 82b of handle 82.If make handle 82 rearward move, then plate spring part 103 elastic deformation and reaction force (elastic force) increase, and thus the operating physical force of handle 82 increases.If make handle 82 rearward move further, then leading section 103b gives prominence to from recess 82b3 and is moved upward, and in this moment, the abutted position of leading section 103b sharply changes and reaction force (elastic force) reduces.

So-called click effect is given to user owing to sharply can be reduced by the operating physical force of this handle 82, so the breech lock 83 action of handle 82 can being passed on clearly to produce to the sense of touch of user removes action, thus refrigerator that serviceability can be provided good.

In addition, the recess 82b3 due to the back side 82b using the handle 82 of the leading section 103b of plate spring part 103 carries out the cataclysm of above-mentioned resistance sense, so reliably can carry out the action of plate spring part 103.

Further, the leading section 103b of plate spring part 103 is the shape with cylindric etc. curvature, and the leading section 103b of plate spring part 103 can not be hooked on the back side 82b of handle 82, slides swimmingly, carries out reliable action.In addition, owing to being coated with the lubricant g such as lubricating grease near the contact site contacted with the back side 82b of handle 82 of the leading section 103b in plate spring part 103, so the contact of the back side 82b of handle 82 and the leading section 103b of plate spring part 103 becomes smooth and easy, more reliably carry out the action of plate spring part 103, reliability is high.

In addition, be concave shape upward owing to making lower edge 74t1, the 74t2 of vegetable compartment separator 74, even if so when the base plate 6bt that lower floor holds container 6b be warpage be configured as convex, also vegetable compartment separator 74 can be placed in the commitment positions that lower floor holds container 6b.Therefore, it is possible to reliably form, upper strata is held the bolt lock mechanism 80 that container 6c is locked in the assigned position of lower floor accommodation container 6b.

As the concrete effect of bolt lock mechanism 80, as described below.

Because bolt lock mechanism 80 is the structures via the bellcrank 93 of conversion direction upward, rearward for the upper end of handle 82 movement being passed to breech lock 83 in the mode of movement upward, so unlock by enabling handle 82 rearward movement make breech lock 83 be moved upward.

And, for the first arm 96 becoming driving side from handle 82 to bellcrank 93 transmitting force and the second arm 98 becoming slave end from bellcrank 93 to breech lock 83 transmitting force, the inner side of the left and right width of handle 82 is configured in due to the first arm 96, second arm 98 be configured in than the left and right width of handle 82 arrange in the outer part as in the breech lock housing 81 of fixed frame, even if also do not interfere with handle 82 so the second arm 98 rotates, thus make bolt lock mechanism 80 lightening in the longitudinal direction, and food containment space can be guaranteed.

In addition, due to bellcrank 93 the second arm 98 and be integrally provided on the left and right sides balanced configuration of latch arms 99 at handle 82 at the two ends of the left and right directions of breech lock 83 with " コ " shape roughly upward, so breech lock 83 by the second arm 98 balancedly on lift the left and right sides.Therefore, make breech lock 83 be moved upward the having stable behavior making to unlock, thus reliably carry out latch-release action.

Further, relative to the latch arms fulcrum 100 accepted via the second arm 98 from the power of bellcrank 93, breech lock 83 is configured at roughly.Therefore, the power that latch arms 99 accepts from the second arm 98 is consistent with the direction that breech lock 83 rises and produce bending moment hardly, thus breech lock 83 can not tilt, and has the effect of the having stable behavior of breech lock 83.

In addition, this refrigerator 1 has following effect.

1., by separator 74 and the upper strata accommodation container 6c division lower floor accommodation container 6b of loading and unloading type, obtain the suitable airtight conditions close to approximate air-tight state, and inside is remained high humidity and prevents from condensing, and automatically lock when vegetable compartment is closed.Thus, the freshness being suitable for foodstuff storing (particularly greengrocery) can be provided to maintain and improve the refrigerator of serviceability.

2. the separator that can freely load and unload is set, this separator lower floor's vegetable compartment (accommodation box) is divided into the beverage of the container being suitable for putting into market sale etc. tall and big food accommodation anterior spatial accommodation and utilize suitable airtight conditions close to air-tight state to maintain the rear portion spatial accommodation of high humidity, and breech lock carrier is set on separator.In the front portion of upper strata vegetable compartment, be arranged through lever operated and move up and down thus the breech lock engaging relative to breech lock carrier, depart from.When vegetable compartment is closed, the breech lock being located at upper strata vegetable compartment (little thing box) is crossed the breech lock carrier of separator and automatically locks.Thus, even if user does not operate action bars at every turn, rear portion spatial accommodation also can keep high humidity, and locks reliable and improve serviceability.

3. handling vegetable compartment separator 74 is freely configured to, when can be chimeric with breech lock 83 except breech lock carrier 75 correct towards except, for installing in mode reverse up and down, the recess 74d of vegetable compartment separator 74 and be located at the protuberance 76b separating guide 76 and interfere and cannot install.Therefore, can not oppositely install vegetable compartment separator 74, thus breech lock 83 is fixed with the position relationship of breech lock carrier 75, and has and can reliably breech lock 83 is embedded in breech lock carrier 75 and enter line-locked effect.

4. due to the breech lock carrier 75 that makes to utilize breech lock 83 and be located at vegetable compartment separator 74 to lock upper strata hold container 6c and vegetable compartment separator 74 position, to hold container 6c with upper strata because of falling into of obtaining of recess 70 and protuberance 71 and hold the chimeric position consistency of container 6b with lower floor, so upper strata holds container 6c and lower floor accommodation container 6b is fitted together to because falling in left and right sides, and central portion is locked via bolt lock mechanism 80 and vegetable compartment separator 74.Therefore, the location that upper strata holds container 6c is reliable, thus has and can will be held in rear portion spatial accommodation 6b2 that container 6b, vegetable compartment separator 74 and upper strata accommodation container 6c impale the effect of the airtight conditions being maintained suitable by lower floor.

5. the close central authorities of the front portion of container 6c are held on upper strata, be provided with the bolt lock mechanism 80 possessing the breech lock 83 moved up and down by the operation of handle 82, the breech lock carrier 75 chimeric with breech lock 83 is arranged on the upper end of vegetable compartment separator 74, this vegetable compartment separator 74 is configured to hold container 6b relative to lower floor and can freely loads and unloads.

And, owing to becoming by making breech lock 83 and breech lock carrier 75 be fitted together to the state locking upper strata accommodation container 6c relative to lower floor accommodation container 6b and vegetable compartment separator 74, so the rear portion spatial accommodation 6b2 being held the lower floor accommodation container 6b that container 6b, vegetable compartment separator 74 and upper strata accommodation container 6c impale by lower floor can be made to be in the suitable airtight conditions being suitable for maintaining high humility, thus there is the effect of the refrigerator that can provide the freshness that can maintain greengrocery.

6. according to the present embodiment, also be configured to, close from the position that rearward movement is opened forwards movement if upper strata holds container 6c, then breech lock 83 crosses the breech lock carrier groove 74c being located at vegetable compartment separator 74, and to locking between upper strata accommodation container 6c and vegetable compartment separator 74, thus only closedown upper strata accommodation container 6c just automatically locks, and does not need specially to lock, thus can provide easy-to-use refrigerator when closing.
