Head rail 203, middle guide rail 221, cabinet guide rail 222 and rotation holding components 145 are assemblied on inner casing 110 with the state of assembling in advance.

Below by the assembling of 202 pairs of inner casings 110 of explanation track-type facilities.

As shown in Figure 4, on cabinet guide rail 222, integrally formed guide rail department of assembly 223 is configured to simultaneously contact with the side surface part of inner casing 110, and by screw 400, is fixed to the sidepiece of inner casing 110.

Therefore now, because the inner casing 110 as fitting surface is mainly by resin forming, even if screw 400 is directly fixed to inner casing 110, inner casing 110 is also difficult to guarantee to stand put on the intensity of the load of track-type facilities 202.

Therefore,, for fixed guide device 202 reliably, guide rail department of assembly 223 is assemblied on the guide rail holding member 270 being embedded in heat-insulating material 111 by inner casing 110.

Guide rail holding member 270 is made by the metal material of for example iron.Guide rail holding member 270 is fixed on the precalculated position of inner casing 110 inner surfaces in advance.Inner casing 110 and shell 112 between fill bury foamed thermal insulating thereafter.In this way, can more improve 270 pairs of confining forces that put on the load of track-type facilities 202 of guide rail holding member.

Guide rail holding member 270 is by whole formation of the interior anti-stop 270b of falling that is fixed to the guide rail maintaining part 270a of guide rail department of assembly 223 by screw 400 and prevents from falling in track-type facilities 202.The anti-stop 270b that inside falls 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 forming from heat-insulating material 111 side close contact inner casings 110.

More specifically, inside falling anti-stop 270b forms from the bottom of guide rail maintaining part 270a and leaves inner casing 110 to shell 112 bendings.In addition, inside falling the distal portion of anti-stop 270b forms and is bent downwardly.Heat-insulating material 111 is filled, and the horizontal flange part of anti-stop 270b of inside falling has the face of receiving heat-insulating material 111, and cuts in heat-insulating material 111.In this way, can guarantee the intensity of guide rail holding member 270.Therefore, can prevent that guide rail department of assembly 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.

As horizontal flange part interior, falling anti-stop 270b can whole form from the upper bend of guide rail maintaining part 270a, and interiorly falls anti-stop 270b and can be respectively formed at upper and lower on both.When interior fall anti-stop 270b 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 of receiving heat-insulating material 111, and cuts up and down in heat-insulating material 111.In this way, can further guarantee the intensity of guide rail holding member 270.

Formation bottom surface, both sides stage portion 108a at the partition wall 108 of the underside wall as refrigerating chamber 104.Bottom surface stage portion 108a forms the height of the high step of central portion with the datum level that is compared to partition wall 108 on 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 upper side wall face that the 110a of side step portion forms in refrigerating chamber 104 caves in shell 112 sides, 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.In this way, can suppress track-type facilities 202 and stretch in memory space, and can increase the integral width of the container 206 in refrigerating chamber 104.Due to this reason, can reduce idle space.

Because track-type facilities 202 is arranged on bottom surface stage portion 108a, goes up and assemble, therefore can improve workability.In addition,, because the part of bottom surface stage portion 108a has the large wall thickness perpendicular to partition wall 108, even if the metal guide rail device 202 therefore in refrigerating chamber 104 is cooled, also can prevent partition wall 108 dewfall as the end face of the vegetable compartment 103 of refrigerating chamber 104 belows.

Fig. 5 be illustrate when when front is watched according to the sectional view of the structure of the inner casing 110 vegetable compartment 103 of the refrigerator 100 of the first exemplary embodiment of the present invention and the department of assembly between track-type facilities 202.

Even in the vegetable compartment 103 forming in the foot of refrigerator 100, guide rail holding member 280 is also configured in heat-insulating material 111.Guide rail holding member 280 comprises guide rail maintaining part 280a and the interior anti-stop 280b of falling.

Guide rail maintaining part 280a is in fact L font, comprises standing flange portion and horizontal flange part, and with side surface part and the bottom surface sections close contact of inner casing 110.Inside fall anti-stop 280b and whole formation of horizontal flange part as the bottom surface sections of guide rail maintaining part 280a, and form in the direction of leaving inner casing 110 lower flange downward.

In this way, the anti-stop 280b that inside falls is embedded in heat-insulating material 111, as lower flange downward.Therefore, even if the moment loading in the direction of toppling in the refrigerator inner side of vegetable compartment 103 falls the heat-insulating material 111 of bottom of anti-stop 280b and stops in guide rail department of assembly 223, being also filled in as the movement of the interior anti-stop 280b of falling of lower flange.In this way, can prevent that guide rail holding member 280 from toppling over, and can guarantee the intensity of guide rail holding member 280.Due to this reason, can prevent that the track-type facilities 202 of vegetable compartment 103 from toppling over to refrigerator inner side.

Formation bottom surface, both sides stage portion 401a at the underside wall 401 of vegetable compartment 103.Bottom surface stage portion 401a forms the height of the high step of central portion with the datum level that is compared to underside wall 401 at depth direction.Track-type facilities 202 is configured on the stage portion 401a 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 forms from the upper side wall face in vegetable compartment 103 in shell 112 sides depressions, and has little wall thickness.

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

In this way, because track-type facilities 202 is arranged on bottom surface stage portion 401a above, and be fixed to the 110a of side step portion by screw, therefore can suppress track-type facilities 202 and stretch in memory space.Therefore, can increase the integral width of the container 206 in vegetable compartment 103, and can reduce idle space.

Because track-type facilities 202 is arranged on bottom surface stage portion 401a, goes up and assemble, therefore can improve workability.In addition, because the wall thickness of the heat-insulating material 111 of underside wall 401 belows increases, so the part of bottom surface stage portion 401a can be guaranteed 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, the sliding door 201 that is positioned at the vegetable compartment 103 of refrigerator bottom is positioned at the position that user easily places body weight.Therefore,, except the load of the content of stores, external load also can put on the sliding door 201 of vegetable compartment 103.Yet, because guide rail holding member 280 can fall by the guide rail maintaining part 280a of L font in fact with as lower flange interior, anti-stop 280b is whole to be formed, the track-type facilities 202 that therefore can prevent bottom sliding door 201 is toppled over, and makes it possible to give the structure of sliding door 201 rigidity.

In each refrigerating chamber 104 and vegetable compartment 103, the 110a of side step portion is configured to reduce the wall thickness of side.As being directed to this countermeasure, position configuration vacuum heat insulation materials (not shown) that can be corresponding in the part with mounting guide rail device 202.More specifically, in each refrigerating chamber 104 and vegetable compartment 103, the vacuum heat insulation materials that is highly greater than the distance between track-type facilities 202 is attached to shell 112, makes it possible to guarantee thermal insulation.

Below by the assembling between explanation sliding door 201 and track-type facilities 202.

Fig. 6 is illustrated in the perspective view with track-type facilities 202 states connected to one another according to sliding door in the refrigerator 100 of the first exemplary embodiment of the present invention 201.

Sliding door 201 comprises the inner panel 211 of the whole inner surface that substantially covers sliding door 201, and door frame 205.Inner panel 211 is the plate-shaped members that form by vacuum forming.The door frame 205 that is directly fixed to inner panel 211 is connected to by screw etc. the head rail 203 that forms track-type facilities 202.In this way, sliding door 201 is configured to be drawn out or be pushed back by the function of track-type facilities 202.

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

Door frame 205 is included in that end edge portion corresponding to a side with door frame 205 forms and along the bend 241 of inner panel 211 bendings of sliding door 201.Bend 241 is assemblied in the part of sliding door 201 of the close end top of head rail 203.

When expansion section 281 is configured between bend 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 track-type facilities 202 of bottom and the undercapacity of the department of assembly between sliding door 201 that are assemblied in sliding door 201 are compensated, and make it possible to open and close smoothly sliding door 201.

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

By above-mentioned structure, even if gripping sliding door 201, user pulls out or pushes back sliding door 201, stress is also dispersed to bend 241 and the part being connected by door frame 205, and does not concentrate on the department of assembly of head rail 203.In this way, as a whole, the constant intensity between sliding door 201 and head rail 203 can be improved.

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

In this case, imagination guarantees that track-type facilities 202 is assemblied in the door frame 205 of the required minimum intensity of the situation of near middle position of above-below direction of sliding door 201.By using this door frame 205, the same with the example of the present embodiment, open and close sliding door 201 be configured under the state below the middle part of above-below direction of sliding door 201 at track-type facilities 202 before and after.

In this case, due to the undercapacity of door frame 205 with the fixed part side of sliding door 201, door frame 205 or inner panel 211 can distortion.As a result, be configured in filler 207 on sliding door 201 separated with adiabatic main body 101 and form gap, and can occur such as in mass defects such as refrigerator 100 interior frostings.

When the department of assembly between sliding door 201 and head rail 203 is positioned at the bottom of sliding door 201, user grips the top of sliding door 201 and pulls out or push back sliding door 201, makes the moment that acts on department of assembly become larger.

Yet in the present embodiment, adopt the door frame 205 with the expansion section 281 projecting upwards from department of assembly, and container fixed part 301 is configured in top, department of assembly.Due to this reason, configurable above department of assembly as the position of the fulcrum of tensile strength, and the moment that acts on department of assembly reduces.The department of assembly that therefore, can prevent head rail 203 damages.

Below by the position relationship illustrating in greater detail between container 206 and track-type facilities 202.

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

In this way, because track-type facilities 202 is configured in two bottoms of sliding door 201, so 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 schematically illustrated according to the figure of the configuration of the track-type facilities 202 in the refrigerator 100 of the first exemplary embodiment of the present invention and container 206.Fig. 8 A to Fig. 8 C amplifies the end that container 206 is shown.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 is not shown.

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

By above structure, the maximum of sliding door 201 is extracted distance out can make the wide-open length of opening that makes container 206.More specifically, when vegetable compartment 103 standard-sized sheet, the end below of container 206 is positioned at immediately the place ahead above of the sliding door 201 of vegetable compartment 103 tops.Due to this reason, the food of depositing and take out the rear side of container 206 can become easy.Due to the sliding door 201 on container 206 Bu Gan Wataru tops, thus the assembling of container 206 and dismounting can easily carry out.

Below will describe container 206 in detail.

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

The flange part forming is outwards given prominence to by the surrounding that container 206 is included in opening.More specifically, in upper end above, form the 206a of front flange portion, in the upper end of side, form the 206b of side flanges portion, and form the 206c of rear flange portion in upper end below.The 206a of front flange portion, the 206b of side flanges portion and the 206c of rear flange portion form continuously.Each flange part form respectively folding before, side and sidewall below, and aspect weight reduction, preferably there is the inside of hollow.Flange part forms the intensity of the opening that makes it possible to increase container 206.

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

In the stage portion 262 forming in the bottom of two sides of container 206, at least one side of front side and rear side, form and downwards outstanding jut 206d one-body molded with container 206.

In this way, as the position of the fulcrum of tensile strength, be positioned at the rear of sliding door 201, make it possible to reduce to act on the moment of department of assembly.In this way, can prevent the damage such as department of assembly, guide rail department of assembly 223 of head rail 203.

In the outside of stage portion 262, at fore-and-aft direction (depth direction), form the side fin portion 266 of narrow boards shape, to cover jut 206d.Side fin portion 266 forms from the two ends of stage portion 262 outstanding downwards, so that the plane of container 206 sides is to downward-extension.

In the bottom of container 206, form from bottom inwardly outstanding bottom surface rib 206e.Bottom surface rib 206e is in the front side at the center of the depth direction of container 206, that is, container 206 packs sliding door 201 sides of vegetable compartment 103 when interior into and forms.Two sides that bottom surface rib 206e traverses container 206 longitudinally form at width (left and right directions).In addition, rib 206e in bottom surface forms the top with the top, position that is positioned at stage portion 262.

Container 206 is divided into two regions by bottom surface rib 206e,, is configured in first storage part 263 and the second storage part 264 that is configured in rear side of front side that is.The degree of depth of the first storage part 263 is configured to darker 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, at fore-and-aft direction (depth direction), from the bottom surface of the second storage part 264, give prominence to downwards and form narrow rectangle column protuberance 265.Protuberance 265 forms in the almost whole part at the second storage part 264 two ends, and its height equates substantially with the height of the bottom surface of the first storage part 263.

Container inside in the bottom surface of the second storage part 264, is formed on flank 267 inside flat a plurality of bottom surfaces of the outstanding left and right elongation in refrigerator inner side (make progress).

In addition, the outside of containers in the bottom surface of the second storage part 264 is formed on flank 268 outside the netted bottom surface of giving prominence in refrigerator outside (downwards) between protuberance 265.

In this case, by the assembling of 206 pairs of door frames 205 of explanation container.

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

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

In the nick shaped fixing hole (not shown) that the jut 206d forming in the stage portion 262 of container 206 forms in being inserted in door frame 205.

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

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

In addition, the outer upper end portion of door frame 205 is covered by side fin portion 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 outstanding downwards from the lower surface of the middle guide rail 221 as moving guide rail.In other words, protuberance 265 outstanding make its lower end comprise sliding door 201 lower surface horizontal plane S1 and comprise between the horizontal plane S2 of lower surface of middle guide rail 221.

In this way, protuberance 265 is formed on the two ends of narrow 261, makes it possible to improve the intensity of container 206, and forms rib etc. without the side at container 206.

The 206a of front flange portion of container 206 is fixed to the container fixed part 301 of sliding door 201, and jut 206d and side fin portion 266 are fixed to door frame 205.In this way, the track-type facilities 202 of bottom and the undercapacity of the department of assembly between sliding door 201 that are assemblied in sliding door 201 are compensated, and make it possible to open and close smoothly sliding door 201.

Protuberance 265 is outstanding downwards from the lower surface of the middle guide rail 221 as moving guide rail.In this way, user can prevent that finger or toe etc. are sandwiched between the leading section B of middle guide rail 221 and the rearward end C of the first storage part 263 or between the leading section B of middle guide rail 221 and the rearward end D of sliding door 201.If finger, toe etc. insert the part between the leading section B of middle guide rail 221 and the rearward end D of the rearward end C of the first storage part 263 or sliding door 201 from the side, finger waits and contacts with protuberance 265, and can further not insert.Now, even if sliding door 201 is closed under this state, finger, toe etc. can not be jammed yet.

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

In addition, protuberance 265 protrudes the bottom surface that has with the first storage part 263 plane in sustained height.In this way, upper even if container 206 is removed and is placed on floor etc., can not make because of the difference between the first storage part 263 and the degree of depth of the second storage part 264 container 206 integral inclinations, and the stores in container 206 can not toppled over or cave in yet.

Container 206 keeps bottom by door frame 205.Due to this reason, track-type facilities 202 can not separate the space of container 206 sides up and down, and can, due to the generation of the temperature difference between top and the bottom or convection current air pocket, not cause dewfall, frosting etc.

In addition, side fin portion 266 be arranged so that can be below the lower surface of the 206b of side flanges portion and the upper surface of door frame 205 above, form the side of the container 206 of the even shape without convex-concave surface.In 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.In this way, the input to cooling fan (not shown) can be reduced, and the energy-conservation of refrigerator 100 can be realized.Because side can form smooth shape, therefore can improve design.When 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.

Bottom surface rib 206e forms in the front side of central portion, and two sides that bottom surface rib 206e traverses container 206 form at width, makes the degree of depth of the first storage part 263 be configured to be greater than the degree of depth of the second storage part 264.By above-mentioned structure, can guarantee to act on the intensity of the tensile strength at depth direction of the side of container 206.

The hypothesis that has had the first storage part 263 based on container 206 is illustrated the present embodiment.Yet, the invention is not restricted to this structure.For example, in container 206, can be by the second storage part 264 but not the first storage part 263 forms structure.In contrast, structure can have another storage part, for example the 3rd storage part.

Protuberance 265 needn't be always above-mentioned rectangle column.Protuberance 265 can form when sliding door 201 is opened, comprise sliding door 201 lower surface horizontal plane S1 and comprise shape outstanding between the horizontal plane S2 of lower surface of middle guide rail 221.Protuberance 265 can form the shape that the gap between the leading section B of middle guide rail 221 and the rearward end D of the rearward end C of the first storage part 263 or sliding door 201 is reduced.

Based on container 206, be that the hypothesis that is stored in the container in vegetable compartment 103 and refrigerating chamber 104 is illustrated the present embodiment.Yet, even if container 206 is used as being stored in the container in another storeroom of switching chamber 106 for example, also can obtain same effect.

In this case, by another example in following explanation the present embodiment.

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

In container 406, bottom surface rib 406e is formed the below that makes the top of bottom surface rib 406e be positioned at stage portion 262.Compare with above-mentioned container 206, container 406 does not have side fin portion 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.

At container 406, be assemblied under the state on door frame 205, protuberance 265 projects to the lower height of height of the lower surface of the middle guide rail 221 that is compared to 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, below the lower surface of the 206b of side flanges portion and the upper surface of door frame 205 above the side of container 406 can form the even shape without convex-concave surface.Therefore, can reduce along the duct resistance of the side cooling cold air that side direction rear side flows of container 406 in the past.The input to cooling fan (not shown) can be reduced, and the energy-conservation of refrigerator 100 can be realized.Because side can form smooth shape, therefore can improve design.

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

(the second exemplary embodiment)

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

In the present embodiment, by mainly explanation and the difference of the first exemplary embodiment.Explanation for identical structure, operation and function may be omitted.

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

The flange part forming is outwards given prominence to by the surrounding that container 506 is included in opening.More specifically, in upper end above, form the 206a of front flange portion, in the upper end of side, form the 206b of side flanges portion, and form the 206c of rear flange portion in upper end below.The 206a of front flange portion, the 206b of side flanges portion and the 206c of rear flange portion form continuously.Each flange part form respectively folding before, side and sidewall below, and aspect weight reduction, preferably there is the inside of hollow.Flange part forms the intensity of the opening that makes it possible to increase container 506.

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

Identical with the container 206 according to the first exemplary embodiment, the 206a of front flange portion of container 506 is fixed to the container fixed part 301(of sliding door 201 with reference to Figure 12), and jut 206d is fixed to door frame 205.In this way, the track-type facilities 202 of bottom and the undercapacity of the department of assembly between sliding door 201 that are assemblied in sliding door 201 are compensated, and make it possible to open and close smoothly sliding door 201.

More specifically, even if use according to the container 506 of the present embodiment, as the position of the fulcrum of tensile strength, be also positioned at the rear of sliding door 201, make it possible to reduce to act on the moment of department of assembly.Due to this reason, can prevent that 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 is below lower than at least one in the wall face height of with two sides above.In other words, the 206c of rear flange portion is configured in than at least one the lower position in the 206a of front flange portion and the 206b of side flanges portion.

In the bottom of container 506, form from bottom inwardly outstanding bottom surface rib 406e.Bottom surface rib 406e is in the front side at the center of the depth direction of container 506 (the E-E line segment in Figure 14), that is, sliding door 201 sides after container 506 packs in storeroom form.Two sides that bottom surface rib 406e traverses container 506 form 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,, is configured in first storage part 263 and the second storage part 264 that is configured in rear side of front side that is.The degree of depth of the first storage part 263 is configured to darker than the degree of depth of the second storage part 264.

Before container 506, form the passage 365 above being formed by (the above-below direction opening) that form at width a plurality of longitudinal elongated slots.In the side of container 506, form the side passage 366 being formed by a plurality of horizontal elongated slots.

Side passage 366 is in the front side at the center of the depth direction of container 506 (the E-E line segment in Figure 14), that is, sliding door 201 sides after container 506 packs in the storeroom of refrigerating chamber 104 for example form.In addition, side passage 366 below the lower surface of the 206b of side flanges portion and stage portion 262 above form.

Suppose the common metal mould that uses above-below direction to move, by injection mo(u)lding molded container 506.In this case, because when moving up metal die, at the framework laterally forming between elongated slot and metal die, interfere, so be difficult to form horizontal elongated slot in the side of container 506.

Therefore, in the present embodiment, the slide core that is used as the left and right directions at container 506 of a part for metal die to move, by being used injection mo(u)lding molded container 506.In this way, the post processing that forms groove etc. by cutting after injection mo(u)lding is unnecessary, and can easily manufacture the container 506 with the side passage 366 consisting of horizontal elongated slot.

Flowing of the storeroom of the container 506 below explanation configuration being formed as mentioned above, the cold air in for example refrigerating chamber 104.

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

The supply of the cooling cold air 367 outlet (not shown) that upper lateral part forms from container 506.Now, as mentioned above, container 506 is constructed such that wall face height is below lower than the wall face height of other face.In this way, cooling cold air 367 does not increase duct resistance ground and is fed to reposefully in container 506.Be fed to cooling cold air 367 in container 506 forward side flow with the inside of cooled containers 506.

Afterwards, a part for cooling cold air 367 is by passage 365 above, and in the space between container 506 and the inner panel 211 of sliding door 201 from the downward side flow of upside.Cooling cold air 367 along the bottom surface of container 506 in the past side direction rear side flow, and from the rear side bottom surface of container 506 be back to container 506 the suction inlet (not shown) that forms of side lower part.

A part for cooling cold air 367 is by side passage 366, and in the space between container 506 and inner casing 110, side direction rear side flows in the past, and is back to the suction inlet of the rear side lower part formation of container 506.

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

Because side passage 366 forms above the upper surface of track-type facilities 202, even if therefore container 506 is drawn out of together with sliding door 201, can not see track-type facilities 202 as mechanical part, door frame 205 etc. by side passage 366 yet.Due to this reason, can realize the structure with good appearance and good design.

In the side of container 506, at rear side (near outlet side), do not form side passage 366.In this way, can prevent that a part for the cooling cold air 367 of upper lateral part supply from container 506 is not circulated to the front side in storeroom, and auto-returned is to the rear side bottom surface of container 506.In this way, the inside of cooled containers 506 effectively.

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

Therefore because groove forms at upside, when container 506 is drawn out of together with sliding door 201, can suppresses cold air in container 506 outside container 506, flow out outside storeroom, and can realize the energy-conservation of refrigerator 100.

The top of bottom surface rib 406e is arranged on the position of the below of stage portion 262, and below the lower surface of the 206b of side flanges portion and stage portion 262 above do not form depressed part.Except side passage 366, below the lower surface of the 206b of side flanges portion and stage portion 262 above do not form convex-concave surface.In this way, can reduce along the duct resistance of the side cooling cold air 367 that side direction rear side flows of container 506 in the past.Because side forms smooth shape, therefore can improve design.

Same in the present embodiment, the 206a of front flange portion of container 506 is fixed to the container fixed part 301 of sliding door 201, and jut 206d is fixed to door frame 205, so that the undercapacity of the department of assembly between compensation track-type facilities 202 and sliding door 201.Due to this reason, when sliding door 201 moves forward and backward execution opening and closing operations, in the tensile strength of depth direction, act on the side of container 506.

Yet in the present embodiment, because side passage 366 only forms in the front side of the side of container 506, so the intensity of the side of container 506 having no lack of.Because side passage 366 consists of horizontal elongated slot, therefore can guarantee the intensity in the tensile strength of depth direction by the framework between groove.

Bottom surface rib 406e forms in the front side at center, and two sides that bottom surface rib 406e traverses container 206 form at width, and the degree of depth of the first storage part 263 is configured to darker than the degree of depth of the second storage part 264.By above-mentioned structure, also can guarantee to act on the intensity of the tensile strength at depth direction of the side of container 506.

Based on side passage 366, be formed on clear the present embodiment of hypothesis of the front side of side.Yet the present invention is not limited to this example.For example,, even only forming above passage 365 and not forming in the structure of side passage 366, also can obtain effect same as described above.

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

In the example shown in Figure 16, the height that side passage 366 forms the lower side that makes side passage 366 is positioned at the higher position (passage lower side, posterior facial height H2< side height H 1) of height below of container 506.In addition, in this example, because side passage 366 is configured in top, therefore when sliding door 201 is drawn out of together with container 506, cold air in container 506 can be suppressed outside container 506, flow out outside the storeroom of for example refrigerating chamber 104, and the energy-conservation of refrigerator 100 can be realized.

(the 3rd exemplary embodiment)

Below, the 3rd exemplary embodiment of the present invention will be described.

Same in the present embodiment, by mainly explanation and the difference of other embodiment.Explanation for identical structure, operation and function may be omitted.

As shown in Figure 18 A, the flange part forming is outwards given prominence to by the surrounding that container 606 is included in opening.More specifically, in upper end above, form the 206a of front flange portion, in the upper end of side, form the 206b of side flanges portion, and form the 206c of rear flange portion in upper end below.The 206a of front flange portion, the 206b of side flanges portion and the 206c of rear flange portion form continuously.

Each flange part form respectively folding before, side and sidewall below, and aspect weight reduction, preferably there is the inside of hollow.Flange part forms the intensity of the opening that makes it possible to increase container 606.

Stage portion 262 is formed at the bottom in two sides of container 606.In stage portion 262, at least one side in front side and rear side forms one-body molded with container 606 and downward outstanding jut 206d.Each jut 206d is inserted in the nick shaped fixing hole 302 forming in door frame 205.

As shown in Figure 17 A, between the upside of container fixed part 301 and inner panel 211, form gap.The 206a of front flange portion of container 606 inserts in this gap, makes it possible to fixed container 606.

In this way, the 206a of front flange portion of container 606 is fixed to the container fixed part 301 of sliding door 601, and jut 206d is fixed to door frame 205.In this way, the track-type facilities 202 of bottom and the undercapacity of the department of assembly between sliding door 201 that are assemblied in sliding door 601 are compensated, and make it possible to open and close smoothly sliding door 601.

More specifically, as the position of the fulcrum of tensile strength, be positioned at the rear of sliding door 601, make it possible to reduce to act on the moment of department of assembly.Due to this reason, can prevent the department of assembly of head rail 203, the damages such as department of assembly of track-type facilities 202.

As shown in Figure 18 B, the upper surface in the expansion section 281 of door frame 205 forms rake 303, and the horizontal part of the position contacting with the horizontal part 304 of door frame 205 at rake 303 formation hole 302.

Conventionally, user confirms the general location in hole 302, and container 606 is placed on door frame 205.User moves forward and backward container 606 a little from the state being placed on door frame 205, and by fixing to complete in jut 206d patchhole 302.

By above-mentioned structure, when container 606 is placed on the place ahead, fixed position, jut 206d is placed on rake 303, and by the weight of container 606, jut 206d easily slides on rake 303.Therefore,, by slight operating physical force or weight, jut 206d is directed to the hole 302 of the horizontal part side formation contacting with rake 303 and inserts wherein.

On the other hand, when container 606 is placed on rear, fixed position, jut 206d is placed on horizontal part 304.Container 606 is moved forward, so that by jut 206d patchhole 302.Now, even if jut 206d moves on horizontal part 304, the rake 303 that makes power that jut 206d moves forward also be subject to contacting with horizontal part 304 suppresses, and to be placed on the situation in the place ahead, fixed position the same with container 606, and jut 206d is directed to hole 302.

When rake 303 forms curve form and forms while contacting with horizontal part 304, jut 206d can move smoothly on rake 303 and horizontal part 304, and jut 206d can be directed to hole 302.

When upper container 408 moves to last location, the 208b of inside protrusions portion with second backward jut 214 with second backward jut 215 contact.In this way, the 208b of inside protrusions portion and second backward jut 214,215 play the effect of the positioning stop that prevents that upper container 408 from transfiniting backward and coming off.

As mentioned above, in above-mentioned structure, the 208b of inside protrusions portion of upper container 408 sides can be used as the brake that prevents that upper container 408 from coming off backward along with moving forward and backward.In this way, can improve rigidity and the intensity of bottom container 726, prevent distortion, and realize brake functionality.When upper end (206c of rear flange portion) in the back forms second backward during jut 215, second backward jut 215 needn't always newly form another, can, by using the wall of the 206c of rear flange portion, the 208b of inside protrusions portion be contacted with the wall of the 206c of rear flange portion.

The 208b of inside protrusions portion is configured in two sides of upper container 408.Due to this reason, the 208b of inside protrusions portion is configured in two ends of bottom container 726, and projection can not damaged the stores in bottom container 726.

Next, the bottom container 716 shown in imagination Figure 25 and the combination between the upper container 408 shown in Figure 26.In this case, in the place ahead of upper container 408, form outside jut 208a, and in the place ahead of the upper end, side of bottom container 716 (206b of side flanges portion), form forward jut 216(and can replace jut and form slot part).When upper container 408 moves to position, forefront, 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 that prevents that upper container 408 from transfiniting forward and coming off.

In above-mentioned structure, the outside jut 208a of upper container 408 sides can be used as the brake that prevents that upper container 408 from coming off forward along with moving forward and backward.In this way, can improve rigidity and the intensity of bottom container 716, prevent distortion, 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 when front is watched according to the sectional view of the another example of the bottom container 736 refrigerator 100 of the 4th exemplary embodiment of the present invention.

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

Now, above opening circumference 506d form and to there is the shape of step 506f that thickness equals the section thickness of framework 506a, make the internal face of bottom container 736 and framework 506a not form step, and side walls forms and does not have convex-concave surface.

Therefore,, even when the bottom of bottom container 736 is supported by door frame 205, the peristome above of the side walls of bottom container 736 or the leading edge portion of facing the wall and meditating as front and back also can be strengthened by the framework 506a with high rigidity.Due to this reason, even if storage food etc. also can suppress bottom container 736 distortion.

In addition, framework 506a and the reverse side face that opening circumference 506d contacts above (above), be formed for the sliding part 506e being slided in upper container 208,308 and 408 front and back.

Sliding part 506e forms the shape with groove shape, and the slip face that two sidepieces in upper container 208,308 and 408 bottoms form moves forward and backward sliding part 506e, makes it possible to move forward and backward upper container 208,308 and 408.

PP resin is used as the moulding material of bottom container 736, and is used as framework 506a than PP resin rigidity and the higher ABS resin of hardness.In this way, than PP resin wearability and the higher ABS resin of resistance to impact, be used as the material of framework 506a, easy contact frame 506a when putting into or taking out stores under upper container 208,308 and 408 states that slide.In this way, can guarantee reliability.Use has good mouldability and is difficult for being stored the PP resin of article damage, and molded bottom surface sections has the bottom container 736 of concaveconvex shape, makes it possible to guarantee surface quality.

Due to framework, 506a has high rigidity, therefore can reduce the deflection at fore-and-aft direction, and can prevent that upper container 208,308 and 408 from coming off from the sliding part 506e of bottom container 736.Because the framework 506a contacting with upper container is made by the ABS resin with high-impact and high-wearing feature, therefore can guarantee reliability, and can obtain good dimensional stability.Therefore, the error between batch can be very little, and can, when guaranteeing the dimensional accuracy of upper container 208,308 and 408, keep sliding.

(the 5th exemplary embodiment)

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

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

Inner panel 211 comprises the inner face recess 602 as recess.Inner face recess 602 forms concavity in the left and right of inner panel 211.The concavity part of inner face recess 602 can be strengthened by metal parts.The reinforcement of the reinforcement of inner face recess 602 and door frame 205 also can be undertaken by same stiffener.A part for container 306 is inserted inner face recess 602, makes it possible to container 306 to be connected to sliding door 251.

Figure 30 illustrates the partial section that is assemblied in the state on sliding door 251 while watching from the side according to the container 306 in the refrigerator 100 of the 5th exemplary embodiment of the present invention.

The 306e of jut forward forming in the place ahead of container 306 is inserted in the inner face recess 602 forming on inner panel 211, makes it possible to container 306 to be connected to sliding door 251.
