As shown in Figure 6, on bin guide rail 222, integrally formed guide rails assembling portion 223 is configured to one side and contacts with the side surface part of inner casing 110, and is fixed to the sidepiece of inner casing 110 by screw 400.

Now, because the inner casing 110 as installed surface is mainly by resin forming, even if therefore screw 400 is directly fixed to inner casing 110, inner casing 110 is also difficult to guarantee to stand the intensity of the load that puts on track-type facilities 202.

Therefore,, for fixed guide device 202 reliably, guide rails assembling portion 223 is arranged on the guide rail holding member 270 of imbedding in heat-insulating material 111 by inner casing 110.

Guide rail holding member 270 is made up of metal materials such as such as iron.Guide rail holding member 270 is fixed to the precalculated position of inner casing 110 inner surfaces in advance.,, between inner casing 110 and shell 112, fill and bury foamed thermal insulating underground thereafter.By this way, can more improve guide rail holding member 270 to putting on the confining force of load of track-type facilities 202.

Guide rail holding member 270 is by being fixed to the guide rail maintaining part 270a of guide rails assembling portion 223 by screw 400 and preventing that the 270b of the enhancing portion entirety of falling in track-type facilities 202 from forming.The 270b of enhancing portion is formed in the horizontal flange part of the bottom of guide rail maintaining part 270a.Guide rail maintaining part 270a is the standing flange portion being formed as from heat-insulating material 111 side close contact inner casings 110.

More specifically, the 270b of enhancing portion is formed as leaving inner casing 110 to shell 112 bendings from the bottom of guide rail maintaining part 270a.In addition, the distal portion of the 270b of enhancing portion is formed as being bent downwardly.Filling heat insulator 111, the horizontal flange part of the 270b of enhancing portion has the face of receiving heat-insulating material 111, and in incision heat-insulating material 111.By this way, can further guarantee the intensity of guide rail holding member 270.Therefore, can prevent that guide rails assembling portion 223 from toppling in the refrigerator inner side of refrigerating chamber 104, that is, can prevent that track-type facilities 202 from toppling in the inner side of refrigerator.Therefore, sliding door 201 can open and close smoothly.

Can form from the upper bend of guide rail maintaining part 270a entirety as the 270b of enhancing portion of horizontal flange part, and the 270b of enhancing portion can be respectively formed at upper and lower on both.When the 270b of enhancing portion be respectively formed at upper and lower both when upper, the horizontal flange part that is formed on the upper and lower of guide rail maintaining part 270a has the face that receives heat-insulating material 111, and cuts up and down in heat-insulating material 111.By this way, can further guarantee the intensity of guide rail holding member 270.

At formation bottom surface, the both sides stage portion 108a of the partition wall 108 of the underside wall as refrigerating chamber 104.Bottom surface stage portion 108a is formed as having the height of the high step of central portion of the datum level that is compared to partition wall 108 at depth direction.Track-type facilities 202 is configured on the stage portion 108a of bottom surface.

On the sidewall face of the inner casing 110 being fixed at track-type facilities 202, form the 110a of side step portion.The 110a of side step portion is formed as from the upper portion side wall face in refrigerating chamber 104 in shell 112 sides depressions, and has little wall thickness.

It is upper that track-type facilities 202 is arranged on bottom surface stage portion 108a, and be fixed to the 110a of side step portion by screw.By this way, can suppress track-type facilities 202 and project in storage space, and can increase the integral width of the container 206 in refrigerating chamber 104.Therefore, can reduce idle space.

Because track-type facilities 202 is upper and assembled by being arranged on bottom surface stage portion 108a, therefore can improve workability.In addition, because the wall thickness of the heat-insulating material 111 of partition wall 108 belows is larger, even if therefore the metal guide rail device 202 in refrigerating chamber 104 is cooled, the part of bottom surface stage portion 108a also can prevent dewfall on the partition wall 108 of the end face of the vegetable compartment 103 as below the stage portion 108a of bottom surface.

Next,, with reference to the vegetable compartment 103 in drawing and pulling type storeroom, the installation between inner casing 110 and the track-type facilities 202 in refrigerator 100 is described.

Especially, in the time that the first crook 331 is configured in the end of bin guide rail 222, the first crook 331 can be easily integrally formed with bin guide rail 222.In addition, because the first crook 331 is configured in the end of bin guide rail 222, so the first crook 331 can easily be inserted the rear side of the bottom surface of storeroom from oblique upper, therefore, can improve the disassembly of track-type facilities 702 for adiabatic main body 101.

In addition, when at bin guide rail 222 side configuration jut, only need form recess at the bottom surface of the bottom surface of partition wall 108 stage portion 108a and inner casing 110 stage portion 401a, and without forming jut.Therefore, can in storeroom, guarantee large actual storage space volume.

In addition, central protrusion portion 332 is engaged in front recess 252, can prevent that track-type facilities 702 from swinging centered by the first crook 331.Therefore because left and right rail device 702 is parallel to each other, so moving guide rail slide smoothly, the operating physical force while making it possible to reduce pull sliding door 201.

In addition,, in the time that track-type facilities 702 is configured in the below of central portion of the above-below direction of sliding door 201, the rear side of the bottom surface of storeroom can easily be inserted in the rear end of bin guide rail 222 from oblique upper.Therefore, can improve the disassembly of track-type facilities 702 for adiabatic main body 101.

Track-type facilities 702 is configured in the below of the central portion of the above-below direction of sliding door 201, makes the major part of the side of container 206 have the even shape that does not form convex-concave surface.By this way, can reduce along the duct resistance of the side cooling cold air that side direction rear side flows of container 206 in the past.As a result, the input to cooling fan (not shown) can be reduced, and the energy-conservation of refrigerator 100 can be realized.Because side is even shape, so can improve design.In the time that container 206 is drawn out of together with sliding door 201, can reduces cold air in container 206 outside container 206, to the outer outflow of vegetable compartment 103, and can realize the energy-conservation of refrigerator 100.

In addition, therefore container 206 keeps bottom by door frame 305.Therefore, track-type facilities 702 can be not upper and lower by the spatial division of container 206 sides, and can, because of the generation of the temperature difference between top and the bottom or convection current air pocket, not cause dewfall or frosting.

Can not configure central protrusion portion 332 and front recess 252, and by the first crook 331 and rear recess 251 fixed guide devices 702.

Industrial usability

As mentioned above, according to the present invention, can realize following special-effect.That is, in drawing and pulling type storeroom, in guaranteeing large actual storage space, suppress sliding door distortion, and reduce cooling gas leakage, make it possible to improve cooling capacity.Therefore, the present invention can be used for comprising the refrigerator of drawing and pulling type storeroom.In addition, the present invention, owing to also can be applicable to modular kitchen for example with drawer etc. and require the field of high-quality and good design, is therefore useful.
