Guide rail maintaining part 280a is substantially in L-shaped, including standing flange portion and horizontal flange part, and with the side surface part of inner shell 110 and bottom surface sections close contact.In the 280b of falling preventing portion and the horizontal flange part of bottom surface sections as guide rail maintaining part 280a be integrally formed, and be formed as on the direction leaving inner shell 110 lower flange portion downward.

In this way, the interior 280b of falling preventing portion is embedded in adiabator 111, as lower flange portion downward.Therefore, even if the moment loading on the direction toppled over inside the refrigerator of vegetable compartment 103 is in guide rail department of assembly 223, in being also filled in as the movement of the 280b of falling preventing portion in lower flange portion, the adiabator 111 of the bottom of the 280b of falling preventing portion stops.In this way, can prevent guide rail holding member 280 from toppling over, and can ensure that the intensity of guide rail holding member 280.Due to this reason, can prevent the track-type facilities 202 of vegetable compartment 103 from toppling over inside refrigerator.

Formation bottom surface, both sides stage portion 401a at the underside wall 401 of vegetable compartment 103.Bottom surface stage portion 401a is formed as the height with the high step of central part of the datum level being used for underside wall 401 at depth direction.Track-type facilities 202 is arranged on the stage portion 401a of bottom surface.

The sidewall level sections of the inner shell 110 being fixed at track-type facilities 202 is formed side step portion 110a.Side step portion 110a is formed as caving in from the upper side wall face in vegetable compartment 103 in shell 112 side, and has little wall thickness.

The side of guide rail department of assembly 223, by the side step portion 110a being clipped in the middle, is fixed to metal guide rail holding member 280 by screw 400.

In this way, owing to track-type facilities 202 is arranged on the stage portion 401a of bottom surface, and it is fixed to side step portion 110a by screw, track-type facilities 202 therefore can be suppressed to stretch in memory space.Therefore, the overall width of container 206 in vegetable compartment 103 can be increased, and Dead space can be reduced.

Owing to track-type facilities 202 is arranged on the stage portion 401a of bottom surface and assembles, workability therefore can be improved.Additionally, because the wall thickness of the adiabator 111 below underside wall 401 increases, so the part of bottom surface stage portion 401a can ensure that thermal insulation.

The sliding door 201 of bottom vegetable compartment 103 is positioned at the downside of the sliding door 201 of refrigerating chamber 104.Due to this reason, when user pulls out sliding door 201, it is positioned at the sliding door 201 of the vegetable compartment 103 bottom refrigerator and is positioned at user and is easily placed the position of body weight.Therefore, except the load of the content of storage article, external load also can put on the sliding door 201 of vegetable compartment 103.But, owing to guide rail holding member 280 can be integrally formed by the guide rail maintaining part 280a of substantially L-shaped with as the 280b of falling preventing portion in lower flange portion, therefore the track-type facilities 202 that can prevent bottom sliding door 201 is toppled over, enabling give the structure of sliding door 201 rigidity.

In each refrigerating chamber 104 and vegetable compartment 103, side step portion 110a is configured to reduce the wall thickness of side.As being directed to this countermeasure, can at the position configuration vacuum heat insulation materials (not shown) corresponding with the part installing track-type facilities 202.More specifically, in each refrigerating chamber 104 and vegetable compartment 103, height is attached at shell 112 more than the vacuum heat insulation materials of the distance between track-type facilities 202, enabling guarantee thermal insulation.

Will be described below the assembling between sliding door 201 and track-type facilities 202.

Fig. 6 is the perspective view of 201 states being connected to each other with track-type facilities 202 that are shown in the refrigerator 100 of the first exemplary embodiment according to the present invention sliding door.

Sliding door 201 includes the inner panel 211 of the whole inner surface substantially over sliding door 201 and door frame 205.Inner panel 211 is the plate-shaped member formed by vacuum forming.The door frame 205 being directly fixed to inner panel 211 is connected to constitute the head rail 203 of track-type facilities 202 by screw etc..In this way, sliding door 201 is configured to be drawn out by the function of track-type facilities 202 or push back.

At the close end of the door frame 205 being connected to inner panel 211, form the expansion section 281 that the major part from door frame 205 projects upwards.In this way, when user grips the upper end pull-out of sliding door 201 particularly sliding door 201 or pushes back sliding door 201, the stress that the close end in head rail 203 produces is concentrated and can be relaxed.

Door frame 205 includes the bending section 241 bent in the end edge portion formation corresponding with the side of door frame 205 inner panel 211 along sliding door 201.Bending section 241 is assemblied in the part of the sliding door 201 above the close end of head rail 203.

When expansion section 281 is arranged between bending section 241 and door frame 205, the size of the fixed part between door frame 205 and sliding door 201 can increase in short transverse.In this way, the intensity deficiency of the department of assembly being assemblied between track-type facilities 202 and the sliding door 201 of the bottom of sliding door 201 is compensated, enabling smoothly opening and closing sliding door 201.

Inner panel 211 includes container mount 301.Container mount 301 is metal parts, is fixed to flat metal plate (not shown) fixing in the foamed thermal insulating on rear side of inner panel 211 by inner panel 211 by screw etc..Above container mount 301, between container mount 301 and inner panel 211, form gap.A part for container 206 is inserted in this gap to fix container 206.

By above-mentioned structure, even if user grips sliding door 201 and pulls out or push back sliding door 201, stress is also dispersed to bending section 241 and the part connected by door frame 205, and does not concentrate on the department of assembly of head rail 203.In this way, as entirety, the fixing intensity between sliding door 201 and head rail 203 can be improved.

Above-mentioned structure for wherein head rail 203 be assemblied in the bottom of sliding door 201, such as structure according to the refrigerator 100 of the present embodiment effective especially.

In such a case, it is contemplated that guarantee that track-type facilities 202 is assemblied in the door frame 205 of the minimum intensity needed for the situation of the near middle position of the above-below direction of sliding door 201.By using this door frame 205, the same with the example of the present embodiment, when track-type facilities 202 be arranged in sliding door 201 above-below direction middle part below before and after opening and closing sliding door 201.

In this case, owing to door frame 205 is not enough with the intensity of the fixed part side of sliding door 201, door frame 205 or inner panel 211 can deform.As a result, it is arranged in filler 207 on sliding door 201 and separates with adiabatic main body 101 and form gap, and the such as mass defect such as frosting in refrigerator 100 can occur.

When department of assembly between sliding door 201 and head rail 203 is positioned at the bottom of sliding door 201, user grips the top pull-out of sliding door 201 or pushes back sliding door 201 so that the moment acting on department of assembly becomes bigger.

But in the present embodiment, adopt the door frame 205 with the expansion section 281 projected upwards from department of assembly, and container mount 301 is arranged in above department of assembly.Due to this reason, it is configurable on the top of department of assembly as the position of the fulcrum of tensile strength, and the moment acting on department of assembly reduces.It is therefore possible to prevent the department of assembly of head rail 203 damages.

Position relationship between container 206 and track-type facilities 202 is described in further detail below.

Fig. 7 is shown in the refrigerator 100 of the first exemplary embodiment according to the present invention rearview of the outline state that container 206 is arranged between track-type facilities 202.

In this way, owing to track-type facilities 202 is arranged in two bottoms of sliding door 201, therefore narrow 261 can expand as much as possible in container 206.Therefore, container 206 can adopt the shape that the volume of memory space increases as far as possible.

Fig. 8 A to Fig. 8 C is the figure of the configuration schematically showing track-type facilities 202 and container 206 in the refrigerator 100 of the first exemplary embodiment according to the present invention.Fig. 8 A to Fig. 8 C amplifies the end illustrating container 206.Fig. 8 A to Fig. 8 C illustrates the position relationship between track-type facilities 202 and container 206, and wherein door frame 205 is omitted and not shown.

In the example of above-mentioned Fig. 7, as shown in Figure 8 A, container 206 has the less narrow of width 261, in order to be inwardly formed stage portion 262 in two ends of bottom.But, the invention is not restricted to this example.Such as, the side of container 206 can have the almost straight shape without stage portion 262, and track-type facilities 202 may be configured to support the side (with reference to Fig. 8 B) at the two ends, left and right bottom container 206.Track-type facilities 202 is also configured to support the downside (with reference to Fig. 8 C) at the two ends, left and right bottom container 206.

By constructed above, the maximum extraction distance of sliding door 201 can make the wide-open length of the opening making container 206.More specifically, when vegetable compartment 103 standard-sized sheet, container 206 end below is positioned at the front before the sliding door 201 above immediately vegetable compartment 103.Due to this reason, the food depositing and taking out the rear side of container 206 can become easy.Due to the sliding door 201 on the not dry top of container 206, therefore the assembly or disassembly of container 206 can be easily performed.

Will be detailed below container 206.

Fig. 9 is the perspective view of the container 206 of the refrigerator 100 of the first exemplary embodiment according to the present invention, and Figure 10 is the side view of the container 206 of refrigerator 100, and Figure 11 is the rearview of container 206 of refrigerator 100.

Container 206 includes the flange part outwardly formed around opening.More specifically, form front flange portion 206a in upper end above, form side flanges portion 206b in the upper end of side, and form rear flange portion 206c in upper end below.Front flange portion 206a, side flanges portion 206b and rear flange portion 206c are continuously formed.Each flange part be formed as separately folded before, side and sidewall below, and preferably there is in alleviating weight the inside of hollow.Flange part is formed so that the intensity of the opening that can increase container 206.

Container 206 is constructed such that wall face height below is lower than at least one in the wall face height of above with two sides.In other words, rear flange portion 206c is arranged in position more less than at least one in front flange portion 206a and side flanges portion 206b.

In the stage portion 262 that the bottom of two sides of container 206 is formed, form one-body molded with container 206 and downward projection of jut 206d at least side of front side and rear side.

In this way, the rear of sliding door 201 it is positioned at as the position of the fulcrum of tensile strength, enabling reduce the moment acting on department of assembly.In this way, can prevent the department of assembly of head rail 203, guide rail department of assembly 223 etc. from damaging.

In the outside of stage portion 262, form the side fin part 266 of narrow boards shape at fore-and-aft direction (depth direction), in order to cover jut 206d.Side fin part 266 is formed as being downwardly projected from the two ends of stage portion 262, so that the plane of container 206 side downwardly extends.

In the bottom of container 206, form the bottom surface rib 206e protruded inwardly from from bottom.Bottom surface rib 206e is in the front side at the center of the depth direction of container 206, i.e. sliding door 201 side when container 206 loads in vegetable compartment 103 is formed.Bottom surface rib 206e traverses two sides of container 206 and is longitudinally formed at width (left and right directions).Additionally, bottom surface rib 206e is formed as having the top above the position being positioned at stage portion 262.

Container 206 is divided into two regions by bottom surface rib 206e, i.e. is arranged in the first storage part 263 of front side and is arranged in the second storage part 264 of rear side.The degree of depth of the first storage part 263 is configured to more deeper than the degree of depth of the second storage part 264.

In the bottom surface of container 206, at the two ends of narrow 261, it is downwardly projected the narrow rectangular cylindrical protuberance 265 of formation from the bottom surface of the second storage part 264 at fore-and-aft direction (depth direction).The protuberance 265 almost whole part at the second storage part 264 two ends is formed, and its height is of substantially equal with the height of the bottom surface of the first storage part 263.

In the container inside of the bottom surface of the second storage part 264, form flat multiple inside bottom surface flanks 267 of left and right elongation (upwards) prominent inside refrigerator.

Additionally, the outside of containers of the bottom surface at the second storage part 264, between protuberance 265, form netted outer side bottom surface flank 268 prominent (downwards) outside refrigerator.

In this case, the container 206 assembling to door frame 205 will be described.

Figure 12 illustrates figure according to the position relationship between the sliding door 201 in the refrigerator 100 of first exemplary embodiment of the present invention, door frame 205 and container 206 when viewed from the side.

The front flange portion 206a of container 206 inserts in the gap being arranged between the container mount 301 on inner panel 211 and inner panel 211, in order to container 206 is fixed to sliding door 201.

The jut 206d formed in the stage portion 262 of container 206 is inserted in door frame 205 in the nick shaped fixing hole (not shown) of formation.

More specifically, jut 206d has the shape that may be inserted in the hole formed in door frame 205.

In this way, container 206 is fixed to door frame 205 with can not damaging disassembly.Particularly, when track-type facilities 202 is assemblied in the two ends bottom container 206, the moment of the power in the pull direction of the pull state of sliding door 201 is orthogonal with fixed-direction.Due to this reason, can effectively alleviate the load being applied on door frame 205 and track-type facilities 202.

Additionally, the outer upper end portion of door frame 205 is covered by side fin part 266.In this way, container 206 can be fixed to door frame 205.

When container 206 is correctly fixed to door frame 205, protuberance 265 is downwardly projected from the lower surface of the intermediate rail 221 as moving guide rail.In other words, protuberance 265 is prominent makes its lower end include between the horizontal plane S1 of lower surface of sliding door 201 and the horizontal plane S2 of lower surface including intermediate rail 221.

In this way, protuberance 265 is formed at the two ends of narrow 261, enabling improve the intensity of container 206, without forming rib etc. in the side of container 206.

The front flange portion 206a of container 206 is fixed to the container mount 301 of sliding door 201, and jut 206d and side fin part 266 are fixed to door frame 205.In this way, the intensity deficiency of the department of assembly being assemblied between track-type facilities 202 and the sliding door 201 of the bottom of sliding door 201 is compensated, enabling smoothly opening and closing sliding door 201.

Protuberance 265 is downwardly projected from the lower surface of the intermediate rail 221 as moving guide rail.In this way, user can prevent finger or toe etc. to be caught in the middle between the leading section B of guide rail 221 and the rearward end C of the first storage part 263 or between the leading section B and the rearward end D of sliding door 201 of intermediate rail 221.If finger, toe etc. are laterally inserted into the part between leading section B and the rearward end C of the first storage part 263 or the rearward end D of sliding door 201 of intermediate rail 221, then finger etc. contact with protuberance 265, without being further inserted into.Now, even if sliding door 201 is closed in this case, finger, toe etc. are without being jammed.

Particularly, in the present embodiment, when container 206 also is stored in the storeroom (vegetable compartment 103) of bottom, the position of lower section 30 to the 50mm of the horizontal plane S1 in the lower surface including sliding door 201, there is the floor placing refrigerator 100.In this case, the probability clamping toe due to user mistakenly increases, and therefore protuberance 265 is configured to prevent finger or toe etc. to be jammed when sliding door 201 is closed by significant.

Additionally, protuberance 265 protrudes the bottom surface having with the first storage part 263 is in the plane of sustained height.In this way, even if container 206 is removed and is placed on floor etc., without making container 206 integral inclined because of the difference between the first storage part 263 and the degree of depth of the second storage part 264, and the storage article in container 206 will not be toppled over or cave in.

Container 206 is kept bottom by door frame 205.Due to this reason, the spatially lower of container 206 side will not be separated by track-type facilities 202, and due to the generation of the temperature difference between top and the bottom or convection current air pocket, will not cause condensation, frosting etc..

Additionally, side fin part 266 is arranged so that above the upper surface of the lower section of the lower surface of side flanges portion 206b and door frame 205, to be formed the side of the container 206 of the even shape without convex-concave surface.In this way, the duct resistance of the side cooling cold air of lateral rear side flowing in the past along container 206 can be reduced.In this way, it is possible to decrease to the input cooling down fan (not shown), and the energy-conservation of refrigerator 100 can be realized.Owing to side can form smooth shape, design therefore can be improved.When container 206 is drawn out of together with sliding door 201, the cold air in container 206 can be reduced and flow out outside container 206, namely outside vegetable compartment 103, and the energy-conservation of refrigerator 100 can be realized.

Bottom surface rib 206e is formed in the front side of central part, and bottom surface rib 206e traverses two sides of container 206 in width formation so that the degree of depth of the first storage part 263 is set to be greater than the degree of depth of the second storage part 264.By above-mentioned structure, it can be ensured that act on the intensity of the tensile strength at depth direction of the side of container 206.

Based on container 206, there is the hypothesis of the first storage part 263 the present embodiment is illustrated.But, the invention is not restricted to this structure.Such as, in container 206, can by the second storage part 264 but not the first storage part 263 forms structure.In contrast, structure can have another storage part, for instance the 3rd storage part.

Protuberance 265 need not be always above-mentioned rectangular cylindrical.Protuberance 265 can be formed when sliding door 201 is opened, and is including the horizontal plane S1 of lower surface of sliding door 201 and is including shape prominent between the horizontal plane S2 of the lower surface of intermediate rail 221.Protuberance 265 can form the shape that the gap between the rearward end C of the leading section B making intermediate rail 221 and the first storage part 263 or the rearward end D of sliding door 201 reduces.

The present embodiment is illustrated by the hypothesis of the container being stored in vegetable compartment 103 and refrigerating chamber 104 based on container 206.But, even if container 206 is used as the container being stored in another storeroom of such as switching chamber 106, it is possible to obtain same effect.

In this case, another example being described below in the present embodiment.

Figure 13 is the side view of another example illustrating the container 406 in the refrigerator 100 of the first exemplary embodiment according to the present invention.

In container 406, bottom surface rib 406e is formed so that the top of bottom surface rib 406e is positioned at the lower section of stage portion 262.Compared with above-mentioned container 206, container 406 does not have side fin part 266, and the height of protuberance 265 is lower than the height of the plane of the bottom surface of the first storage part 263.

When container 406 is assemblied on door frame 205, protuberance 265 projects to the less height of height of the lower surface of the intermediate rail 221 being used for moving guide rail.

In container 406, the top of bottom surface rib 406e is configured to be positioned at the downside of stage portion 262.In this way, in the side of container 406, the side of the container 406 above the lower section of lower surface and the upper surface of door frame 205 of side flanges portion 206b can form the even shape without convex-concave surface.Therefore, the duct resistance of the side cooling cold air of lateral rear side flowing in the past along container 406 can be reduced.The input to cooling fan (not shown) can be reduced, and the energy-conservation of refrigerator 100 can be realized.Owing to side can form smooth shape, design therefore can be improved.

And in container 406, protuberance 265 is downwardly projected from the lower surface of the intermediate rail 221 as moving guide rail.In this way, user can prevent finger or toe etc. from being clamped (with reference to Figure 12) by the gap formed between leading section B and the rearward end C of the first storage part 263 or the rearward end D of sliding door 201 of intermediate rail 221.

(the second exemplary embodiment)

Hereinafter, second exemplary embodiment of the present invention will be described.

In the present embodiment, the difference with the first exemplary embodiment will be mainly described.Explanation for identical structure, operation and function may be omitted.

Figure 14 is the perspective view of the container 506 in the refrigerator 100 of the second exemplary embodiment according to the present invention.

Container 506 includes the flange part outwardly formed around opening.More specifically, form front flange portion 206a in upper end above, form side flanges portion 206b in the upper end of side, and form rear flange portion 206c in upper end below.Front flange portion 206a, side flanges portion 206b and rear flange portion 206c are continuously formed.Each flange part be formed as separately folded before, side and sidewall below, and preferably there is in alleviating weight the inside of hollow.Flange part is formed so that the intensity of the opening that can increase container 506.

In the stage portion 262 that the bottom of two sides of container 506 is formed, form one-body molded with container 506 and downward projection of jut 206d at least side of front side and rear side.Each jut 206d is inserted in door frame 205 in the nick shaped fixing hole (not shown) of formation.

Identical with the container 206 according to the first exemplary embodiment, the front flange portion 206a of container 506 is fixed to the container mount 301(of sliding door 201 with reference to Figure 12), and jut 206d is fixed to door frame 205.In this way, the intensity deficiency of the department of assembly being assemblied between track-type facilities 202 and the sliding door 201 of the bottom of sliding door 201 is compensated, enabling smoothly opening and closing sliding door 201.

Even if more specifically, use container 506 according to the present embodiment, it also is located at the rear of sliding door 201 as the position of the fulcrum of tensile strength, enabling reduce the moment acting on department of assembly.Due to this reason, can prevent the department of assembly of head rail 203 or the department of assembly of track-type facilities 202 from damaging.

Container 506 is constructed such that wall face height below is lower than at least one in the wall face height of above with two sides.In other words, rear flange portion 206c is arranged in position more less than at least one in front flange portion 206a and side flanges portion 206b.

In the bottom of container 506, form the bottom surface rib 406e protruded inwardly from from bottom.Bottom surface rib 406e is in the front side at the center (the E-E line segment in Figure 14) of the depth direction of container 506, i.e. loads the sliding door after in storeroom 201 side at container 506 and is formed.Bottom surface rib 406e traverses two sides of container 506 and is formed at width.The top of bottom surface rib 406e is configured to be positioned at the downside of the position of stage portion 262.

Container 506 is divided into two regions by bottom surface rib 406e, i.e. is arranged in the first storage part 263 of front side and is arranged in the second storage part 264 of rear side.The degree of depth of the first storage part 263 is configured to more deeper than the degree of depth of the second storage part 264.

Before container 506, form passage 365 before being made up of (above-below direction opening) the multiple longitudinal elongated slot formed at width.In the side of container 506, form the side passage 366 being made up of multiple horizontal elongated slots.

Side passage 366 is in the front side at the center (the E-E line segment in Figure 14) of the depth direction of container 506, i.e. loads sliding door 201 side after in the storeroom of such as refrigerating chamber 104 at container 506 and is formed.Additionally, side passage 366 is in the lower section of lower surface of side flanges portion 206b and being formed over of stage portion 262.

Assume the common metal mould using above-below direction to move, by injection mould container 506.In this case because when move up metal die time, the framework formed between horizontal elongated slot is interfered with metal die, so being difficult to form horizontal elongated slot in the side of container 506.

Therefore, in the present embodiment, the slide core that the left and right directions at container 506 as a part for metal die moves is used, by using injection mould container 506.In this way, the post processing by cutting formation groove etc. is unnecessary after moulding, and can be easily manufactured the container 506 with the side passage 366 being made up of horizontal elongated slot.

Will be described below the flowing of cold air in the configuration storeroom of container 506 configured as described above, such as refrigerating chamber 104.

Figure 15 is the figure that the cold air flow in the storeroom of the dispensing containers 506 in second exemplary embodiment of the present invention is described.

The outlet (not shown) supply that cooling cold air 367 is formed from the upper back of container 506.Now, as it has been described above, container 506 is constructed such that the wall face height lower than other face of the wall face height below.In this way, cooling cold air 367 is not smoothly fed in container 506 with not increasing duct resistance.It is fed to the inside to cool down container 506 of the cooling cold air 367 forward side flowing in container 506.

Afterwards, cooling cold air 367 in part through above passage 365, and flow from the upper side to the lower side in the space between the inner panel 211 of container 506 and sliding door 201.Cooling cold air 367 is along the bottom surface lateral rear side flowing in the past of container 506, and the suction inlet (not shown) that the back lower being back to container 506 from the rear side bottom surface of container 506 is formed.

Cooling cold air 367 in part through side passage 366, in the past lateral rear side flowing in the space between container 506 and inner shell 110, and the suction inlet that the back lower being back to container 506 is formed.

Even if in the present embodiment, container 506 is also kept bottom by door frame 205.Due to this reason, the lateral space of container 506 will not be divided into upper and lower by track-type facilities 202, and due to the generation of the temperature difference between top and the bottom or convection current air pocket, will not cause condensation or frosting.

Owing to side passage 366 is being formed over of upper surface of track-type facilities 202, even if therefore container 506 is drawn out of together with sliding door 201, see as the track-type facilities 202 of mechanical part, door frame 205 etc. without by side passage 366.Due to this reason, it may be achieved have the structure of good appearance and good design.

In the side of container 506, rear side (near outlet side), do not form side passage 366.In this way, can prevent the part for the cooling cold air 367 of the upper back supply from container 506 from not circulating the front side to storeroom, and automatically return to the rear side bottom surface of container 506.In this way, the inside of container 506 can effectively be cooled down.

Side passage 366 is made up of horizontal elongated slot.Due to this reason, compared with the situation forming longitudinal elongated slot, the duct resistance occurred when cooling down cold air 367 by groove of forwards flows outside inside the rear from container 506 can be reduced.The input to cooling fan (not shown) can be reduced, and the energy-conservation of refrigerator 100 can be realized.

Owing to groove is formed in upside, therefore when container 506 is drawn out of together with sliding door 201, can suppress the cold air in container 506 outside container 506, namely flow out outside storeroom, and the energy-conservation of refrigerator 100 can be realized.

The top of bottom surface rib 406e is arranged on the position of the lower section of stage portion 262, and at the depressed part not formed above of the lower section of lower surface of side flanges portion 206b and stage portion 262.Except side passage 366, at the convex-concave surface not formed above of the lower section of lower surface of side flanges portion 206b and stage portion 262.In this way, the duct resistance of the side cooling cold air 367 of lateral rear side flowing in the past along container 506 can be reduced.Owing to side forms smooth shape, design therefore can be improved.

Same in the present embodiment, the front flange portion 206a of container 506 is fixed to the container mount 301 of sliding door 201, and jut 206d is fixed to door frame 205, in order to the intensity of the department of assembly between compensation track-type facilities 202 and sliding door 201 is not enough.Due to this reason, when the movable execution opening and closing operations of sliding door 201, the tensile strength at depth direction acts on the side of container 506.

But in the present embodiment, owing to side passage 366 is only formed in the front side of the side of container 506, the therefore intensity of the side of container 506 having no lack of.Owing to side passage 366 is made up of horizontal elongated slot, the intensity of tensile strength at depth direction therefore can be guaranteed by the framework between groove.

Bottom surface rib 406e is formed in the front side at center, and bottom surface rib 406e traverses two sides of container 206 and formed at width, and the degree of depth of the first storage part 263 is configured to more deeper than the degree of depth of the second storage part 264.By above-mentioned structure, it is possible to guarantee the intensity acting on the tensile strength at depth direction of the side of container 506.

The hypothesis formed in the front side of side based on side passage 366 understands the present embodiment.But, the present invention is not limited to this example.Such as, though only formed above passage 365 and do not formed in the structure of side passage 366, it is possible to obtain effect same as described above.

Figure 16 is the side view of the example illustrating the relation between sliding door 201 and the container 506 in second exemplary embodiment of the present invention.

In example shown in figure 16, side passage 366 is formed so that the height of the lower side of side passage 366 is positioned at the higher position of container 506 height below (posterior facial height H2 < side passage lower side height H1).In addition, in this example, owing to side passage 366 is arranged in top, therefore when sliding door 201 is drawn out of together with container 506, can suppress the cold air in container 506 outside container 506, namely flow out outside the storeroom of such as refrigerating chamber 104, and the energy-conservation of refrigerator 100 can be realized.

Container 806 includes upper container 208 and bottom container 906.

Bottom container 906 includes the flange part outwardly formed around opening.More specifically, form front flange portion 206a in upper end above, form side flanges portion 206b in the upper end of side, and form rear flange portion 206c in upper end below.Front flange portion 206a, side flanges portion 206b and rear flange portion 206c are continuously formed.

Each flange part be formed as separately folded before, side and sidewall below, and preferably there is in alleviating weight the inside of hollow.Flange part is formed so that the intensity of the opening that can increase bottom container 906.

In the stage portion 262 that the bottom of two sides of bottom container 906 is formed, form one-body molded with bottom container 906 and downward projection of jut 206d at least side of front side and rear side.Each jut 206d is inserted in door frame 205 in the nick shaped fixing hole (not shown) of formation.

The front flange portion 206a of bottom container 906 is fixed to the container mount 301 of sliding door 201, and jut 206d is fixed to door frame 205.In this way, the intensity deficiency of the department of assembly being assemblied between track-type facilities 202 and the sliding door 201 of the bottom of sliding door 201 is compensated, enabling smoothly opening and closing sliding door 201.

More specifically, be positioned at the rear of sliding door 201 as the position of the fulcrum of tensile strength, enabling reduce the moment acting on department of assembly.Due to this reason, can prevent the department of assembly of head rail 203 or the department of assembly of track-type facilities 202 from damaging.

Bottom container 906 is constructed such that wall face height below is lower than at least one in the wall face height of above with two sides.In other words, rear flange portion 206c is arranged in position more less than at least one in front flange portion 206a and side flanges portion 206b.

Upper container 208 includes jut (aftermentioned) on the side and track flanges 209, and slide anteroposterior on the guide-track groove (not shown) formed in the side flanges portion 206b and inner shell 110 of bottom container 906, enabling on lower portion container 906 and move in inner shell 110.

Figure 22 is from the sectional view of major part according to the sliding part between upper container 208 and the bottom container 906 refrigerator 100 of the 4th exemplary embodiment of present invention when watching in front.

Upper container 208 includes outside jut 208a on the side and inside protrusions portion 208b.Side flanges portion 206b as the lateral upper end of bottom container 906 includes outer ribs 210a and interior side rib 210b.

Outside jut 208a is arranged between outer ribs 210a and interior side rib 210b.Inside protrusions portion 208b is arranged in the inner face side of interior side rib 210b.By above-mentioned structure, upper container 208 slides in bottom container 906.Make the projection of the inside protrusions portion 208b projection than outside jut 208a high, the overlap margin of outside jut 208a is set as about 7mm, and the overlap margin of inside protrusions portion 208b is set as about 15mm so that the overlap margin of inner side is set to be greater than the overlap margin in outside.About the rib of bottom container 906, the height of outer ribs 210a is set to be greater than the height of interior side rib 210b.

Hereinafter, operation and the function of container 806 configured as above will be described.

Firstly, since on the side flanges portion 206b of the lateral upper end as bottom container 906, form two ribs at depth direction, namely outer ribs 210a and interior side rib 210b, therefore can alleviate the deformation of the left and right directions of bottom container 906.

Additionally, the outside jut 208a and inside protrusions portion 208b of the upper container 208 of the sliding part constituted between upper container 208 and bottom container 906, between the outer ribs 210a and interior side rib 210b of bottom container 906, constitute the fit structure of guide rail shape.Due to this reason, the rock deformation pressure of the left and right directions of bottom container 906 dispersibles to upper container 208.The deformation of the left and right directions of bottom container 906 is alleviated also by the rigidity of upper container 208.

Constitute the distance between each jut and each rib of fit structure be set as making the rigid of sliding function and bottom container 906 improve can be compatible value be critically important.Such as, this distance is set as about 1 to 5mm, and the flange part of bottom container 906 is indeformable.In this case, this distance is set such that the gap formed between each jut and each rib for sliding, and when deformation is beyond degree of admission, this gap eliminates, and the deformation that can play bottom container 906 prevents function.

Owing to upper container 208 self also has two juts, namely outside jut 208a and inside protrusions portion 208b, therefore can obtain the structure with high rigidity.Due to this reason, the deformation preventing bottom container 906 can be contributed by upper container indirectly.

Higher than outside jut 208a near the inside protrusions portion 208b of the sidewall of upper container 208, enabling to increase the rigid of upper container 208.

In bottom container 906, outer ribs 210a is set to higher than interior side rib 210b, enabling suppresses or prevents outside jut 208a from coming off from the groove between outer ribs 210a and interior side rib 210b.

As it has been described above, according to the present embodiment, in track-type facilities 202 is assemblied in the structure at the two ends, left and right bottom bottom container 906, can suppress and prevent from becoming the deformation on bottom container 906 top of problem.In this way, the volume of bottom container 906 can increase further, and accommodation can improve.Additionally, by optionally using upper container and bottom container, it may be achieved the improvement of convenience.

Figure 23 is the perspective view of another example illustrating the upper container 308 in the refrigerator 100 of the 4th exemplary embodiment according to the present invention.

In upper container 308, form inside protrusions portion 208b in the whole region of the depth direction of upper container 308.In this way, owing to being formed in the whole region of the depth direction of upper container 308 near the inner projection portion 208b of configuration in the side of upper container 308, therefore the rigidity of the depth direction of upper container 308 and intensity can be improved.

Figure 24 is from the sectional view of major part according to the sliding part between upper container 308 and the bottom container 906 refrigerator 100 of the 4th exemplary embodiment of present invention when watching in front.

The cold air communication mouth 212 being formed about by inside protrusions portion 208b by above-mentioned structure, the rigidity of upper container 308 side and intensity is weakened.But, form inside protrusions portion 208b in the whole region of the depth direction of upper container 308, in order to strengthen rigidity and the intensity of upper container 308.Due to this reason, also can be supplemented even if forming cold air communication mouth 212, the rigidity of upper container 308 and the reduction of intensity near the inside protrusions portion 208b of upper container 308 side at a predetermined interval.

Figure 25 is the zoomed-in view of the major part of the side flanges portion 206b in another example of the bottom container 716 of the refrigerator 100 of the 4th exemplary embodiment according to the present invention, and Figure 26 be upper container 408 another example in the perspective view of major part of vicinity of outside jut 208a in front, side.

Form outside jut 208a in the front of upper container 408, and may replace jut composition groove portion at the rear formation first jut 213(backward of the lateral upper end (side flanges portion 206b) of bottom container 716).When upper container 408 moves to rearmost position, outside jut 208a be configured to first backward jut 213 contact.Outside jut 208a and the first jut 213 backward plays the effect of the positioning stop preventing upper container 408 from transfiniting backward and to come off.

As it has been described above, in this example, the outside jut 208a of upper container 408 side is used as brake, and it prevents bottom container 716 from deforming and prevents what upper container 408 movable from causing to come off backward.In this way, following excellent effect has been given play to, i.e. without forming projection in the bottom of upper container 408, can prevent upper container 408 from coming off backward, and projection will not damage the storage article in bottom container 716.

Figure 27 is the perspective view of the major part of the structure of the side flanges portion 206b in the another example of the bottom container 726 of the refrigerator 100 illustrating the 4th exemplary embodiment according to the present invention and rear flange portion 206c.

In such a case, it is contemplated that the upper container 408 shown in Figure 26 and the combination between the bottom container 726 shown in Figure 27.Inside protrusions portion 208b is configured in the front of upper container 408, and upper end (rear flange portion 206c) after the rear of lateral upper end (side flanges portion 206b) or bottom container 726 of bottom container 726, although jut 214,215(figure 27 illustrates two second jut 214,215 backward, but also can form one of them backward to form second).

When upper container 408 moves to rearmost position, inside protrusions portion 208b and the second jut 214 backward with second backward jut 215 contact.In this way, inside protrusions portion 208b and the second jut 214,215 backward plays the effect of the positioning stop preventing upper container 408 from transfiniting backward and to come off.

As it has been described above, in above-mentioned structure, the inside protrusions portion 208b of upper container 408 side is used as the brake preventing upper container 408 from coming off backward along with moving forward and backward.In this way, rigidity and the intensity of bottom container 726 can be improved, it is prevented that deformation, and realize brake functionality.When below, upper end (rear flange portion 206c) forms the second jut 215 backward, second backward jut 215 need not always be newly formed as another, can pass through to use the wall of rear flange portion 206c, make the wall of inside protrusions portion 208b and rear flange portion 206c contact.

Inside protrusions portion 208b is arranged in two sides of upper container 408.Due to this reason, inside protrusions portion 208b is arranged in two ends of bottom container 726, and projection will not damage the storage article in bottom container 726.

It follows that the bottom container 716 shown in imagination Figure 25 and the combination between the upper container 408 shown in Figure 26.In this case, the front of upper container 408 formed outside jut 208a, and formed in the front of the lateral upper end (side flanges portion 206b) of bottom container 716 jut 216(forward may replace jut constitute groove portion).When upper container 408 moves to forefront position, outside jut 208a is configured to contact with jut 216 forward.In this way, outside jut 208a and forward jut 216 play the effect of the positioning stop preventing upper container 408 from transfiniting forward and to come off.

In above-mentioned structure, the outside jut 208a of upper container 408 side is used as the brake preventing upper container 408 from coming off forward along with moving forward and backward.In this way, rigidity and the intensity of bottom container 716 can be improved, it is prevented that deformation, and realize brake functionality.

In this way, bottom container 716 and upper container 408 have location division (brake functionality), to avoid upper container 408 to deviate from, and can improve convenience.

Figure 28 illustrates from the sectional view of another example according to the bottom container 736 refrigerator 100 of the 4th exemplary embodiment of present invention when watching in front.

In bottom container 736, framework 506a is configured to be different from the parts of bottom container 736.More specifically, framework 506a embeds and is fixed to top-open circumference 506d from above.

Now, top-open circumference 506d forms the shape of the step 506f of the section thickness having thickness equal to framework 506a so that the internal face of bottom container 736 and framework 506a are formed without step, and side walls is formed as not having convex-concave surface.

Therefore, even if when the bottom of bottom container 736 is supported by door frame 205, the side walls of bottom container 736 or the top-open portion of leading edge portion faced the wall and meditated as front and back also can be strengthened by the framework 506a with high rigidity.Due to this reason, though storage food etc., it is possible to suppress bottom container 736 to deform.

Additionally, framework 506a with the reverse side in the top-open circumference 506d face contacted (above), form the sliding part 506e for making upper container 208,308 and 408 slide anteroposterior.

Sliding part 506e is formed as the shape with channel-shaped and the movable sliding part 506e of slip face that two sidepieces bottom upper container 208,308 and 408 are formed, enabling movable upper container 208,308 and 408.

PP resin is used as the moulding material of bottom container 736, and the ABS resin higher than PP resin rigidity and hardness is used as framework 506a.In this way, the ABS resin higher than PP resin wearability and resistance to impact is used as the material of framework 506a, easily contacts framework 506a when putting into or take out storage article when upper container 208,308 slides with 408.In this way, it can be ensured that reliability.Use and there is good mouldability and not easily by the PP resin of storage article damage, mould bottom surface sections and there is the bottom container 736 of concaveconvex shape, enabling guarantee surface quality.

Owing to framework 506a has high rigidity, therefore can reduce the flexure at fore-and-aft direction, and can prevent upper container 208,308 and 408 from coming off from the sliding part 506e of bottom container 736.Framework 506a owing to contacting with upper container is made up of the ABS resin with high-impact and high-wearing feature, it is thus ensured that reliability, and good dimensional stability can be obtained.Therefore, the error between batch can be only small, and while guaranteeing the dimensional accuracy of upper container 208,308 and 408, can keep sliding.

(the 5th exemplary embodiment)

Hereinafter, the 5th exemplary embodiment of the present invention will be described.

Same in the present embodiment, the difference with other embodiments will be mainly described.Explanation for identical structure, operation and function may be omitted.

Figure 29 is the perspective view illustrating the department of assembly between sliding door 251 and the door frame 205 in the refrigerator 100 of the 5th exemplary embodiment according to the present invention.

Inner panel 211 includes the inner face recess 602 as recess.Inner face recess 602 forms concavity in the left and right of inner panel 211.The concave part of inner face recess 602 can be strengthened by metal parts.The reinforcement of inner face recess 602 and the reinforcement of door frame 205 also can be undertaken by same reinforcement plate.A part for container 306 inserts inner face recess 602, enabling container 306 is connected to sliding door 251.

The partial section of the state that Figure 30 is assemblied on sliding door 251 according to the container 306 in the refrigerator 100 of the 5th exemplary embodiment of the present invention when being and illustrate viewing from the side.
