Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention provides a refrigerator compartment at the top of the refrigerator, a freezer compartment at the bottom of the refrigerator, a vegetable compartment between the refrigerator compartment and an opening / closing door supported on the front side of the refrigerator compartment, The present invention relates to a refrigerator including a storage case supported by an inner wall surface of a refrigerator in a freezer compartment and a vegetable compartment, and a drawer door that can be pulled out in a front and rear direction.

[0002]

[Prior art]

 A conventional refrigerator has a plurality of storage chambers suitable for the temperature of each food, which are formed by foaming and filling a heat insulating material between an outer box and an inner box to divide the inside into a plurality of temperature zones. Conventionally, a refrigerator with a freezer at the top, a refrigerator at the center, and a vegetable compartment at the bottom was the mainstream, but recently, refrigerators with various layouts have been proposed.

For example, Japanese Patent Laid-Open No. 5-223431 (referred to as a first conventional example) proposes a refrigerator called a mid-freezer in which a freezer compartment is arranged in the center. Its specific structure is: a refrigerator room with an opening / closing door at the top of the refrigerator, a freezer room with a drawer door that is divided into two stages in the center, and a vegetable room with a drawer door at the bottom. However, a compressor is located at the rear of the vegetable compartment, and a fan motor and heat exchanger are located at the rear of the freezing compartment.

Further, for example, in Japanese Unexamined Patent Publication No. 5-60440 (referred to as a second conventional example), a refrigerator is divided into two storage chambers having an opening / closing door through a partition wall, and the upper storage chamber is divided into two parts. The refrigerator room has a drawer-type vegetable compartment at the bottom, and the lower storage room is a freezer compartment with multiple drawers.

Further, for example, Hitachi, Ltd. has a refrigerator room with an opening / closing door at the top of the refrigerator, a vegetable room / refrigeration room (switchable type) with a opening / closing door with a rotating storage case at the center, In 1980, a refrigerator with a lower part as a refrigerating room equipped with a rotating vegetable storage case and an opening / closing door with an ice making shelf was released as model R-336BRV (referred to as the third conventional example).

Further, for example, in Japanese Utility Model Publication No. 37-18668 (referred to as a fourth conventional example), a storage chamber having upper and lower opening and closing doors is provided, and the refrigerator is placed at the center or the waist of the refrigerator and pulled out. A refrigerator having a multi-purpose storage compartment with a door is disclosed.

[0007]

[Problems to be solved by the device]

 A survey of refrigerator usage shows that the refrigerator is installed side by side with the kitchen sink and is frequently used for standing cooking. The frequency of use is the refrigerator room, then the vegetable room, and then the freezer room. From this standing posture, it can be said that arranging the refrigerator compartment in the upper part, the vegetable compartment in the center, and the freezer compartment in the lower part suits the actual usage.

However, for example, in the first conventional example, although the usability of the refrigerating room is improved, the vegetable room is disposed below the freezing room, which is less frequently used, so that the vegetable room is used in a squatting position. It must be done, and it can be said that the usability of the vegetable room is poor. In particular, because the freshness of vegetables deteriorates quickly, it is not suitable for the actual usage of the vegetable compartment, which must be constantly monitored for freshness, below the freezer compartment where long-term preservation of frozen foods is performed. It is a thing.

[0009] Furthermore, it is known that vegetables are significantly deteriorated in freshness when they are stacked vertically or when unnecessary force is applied. In the first conventional example, a compressor is installed behind the vegetable compartment. Because of this, the back of the vegetable compartment becomes slanted, and the vegetables stored on this slope push other vegetables to reduce the freshness. Furthermore, in the first conventional example, since the freezer compartment whose temperature inside the refrigerator is greatly different from that of the refrigerator compartment or the vegetable compartment is arranged between the refrigerator compartment and the vegetable compartment, the heat insulating material is provided above and below the freezer compartment. Must be provided.

Further, since the freezing compartment is arranged above the vegetable compartment, the heat exchanger and the fan motor, which are arranged along with this, are necessarily arranged above, and the compressor and the heat exchanger are Not only is there a dead space formed between them, but the center of gravity shifts upwards and the refrigerator itself becomes less stable.

On the other hand, for example, in the second and third conventional examples, since the vegetable compartment is arranged at the center, the positional usability of the first conventional example is improved, but this type of fruit is used. Looking at the status of application, since the vegetable compartment is located at a high position of 1000 mm or more, there are problems in coordinating work with the work in the sink and putting in and out of large vegetables.

Further, for example, in the second conventional example, since the vegetable compartment is arranged in the refrigerating compartment, the opening / closing door and the drawer must be opened / closed when the vegetable compartment is used. Moreover, there are problems such as a decrease in the temperature inside the refrigerator and damage when the opening / closing door is closed while the drawer is pulled out.

Further, for example, in the third conventional example, the vegetable compartment can be made into a vegetable compartment by switching the central compartment, but this vegetable compartment / refrigerator is further provided with an opening / closing storage case inside the opening / closing door. Therefore, two opening / closing operations are always required in use. Moreover, in this conventional example, since the opening / closing door and the rotating storage case are opened and closed by one hinge, the center of gravity moves diagonally forward and the stability of the main body deteriorates. Further, in this conventional example, since all the storage chambers are opened / closed doors, there is a problem in the usability of the storage chambers arranged below.

Further, for example, in the fourth conventional example, although the structure of the central storage chamber is disclosed, there is no specific disclosure of the upper and lower storage chambers. Furthermore, there is no specific disclosure as to the refrigerator associated with the internal temperature of each storage room. In addition, since the lowermost storage compartment is an opening / closing door, there is a problem in the usability of the lower storage compartment in the crouching posture.

A first object of the present invention is to provide a refrigerator with good usability by arranging a refrigerator compartment, a vegetable compartment, and a freezer compartment one above the other according to the order of frequency of use.

A second object of the present invention is to provide a refrigerator in which the vegetable compartment has a door structure suitable for a bent posture, and the vegetable compartment is arranged in an operation region optimal for this posture.

A third object of the present invention is to provide a first storage case and a second storage case that can slide on the first storage case in the vegetable compartment, and devise the peripheral side surface and front side shape of the first storage case. In this way, it is possible to provide a refrigerator that is easy to store and take out various vegetables of different sizes and lengths.

A fourth object of the present invention is to provide a refrigerator having a low center of gravity with reduced dead space.

A fifth object of the present invention is to provide a refrigerator having a high freezing efficiency in a freezer compartment.

[0020]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention adopts the following configurations.

An upper part of the refrigerator is provided with a refrigerating compartment, a lower part of the refrigerator is provided with a freezing compartment, and a vegetable compartment is provided between the refrigerating compartment and the freezing compartment. A door is arranged, and a drawer door that is movable in the front-rear direction with respect to the refrigerator is installed at the front of the vegetable compartment together with a storage case. A drawer door that can move in any direction is installed, and the front and rear doors of the opening / closing door, the drawer door of the vegetable compartment, and the drawer door of the freezer compartment are installed so that the respective doors are closed and aligned in the front-rear direction. The height of the upper end of the drawer door of the vegetable compartment is set in the range of 850 mm or more and 1000 mm or less from the floor surface, a compressor is arranged in the lower rear portion of the refrigerator, and heat is exchanged in the rear of the freezing compartment.

At the same time, the size of the nameplate 24 is used as a space for the nameplate 24. The drawer doors 30 and 40 are provided with lateral handles 31 and 41, which are horizontally long handle portions 32 and 42 and concave portions 33 and 43, at the centers of the upper ends.

Next, referring to FIG. 4, the internal structure will be described. In the figure, the housing 2 is formed by foaming and filling a heat insulating material 5 between an outer box 3 made of a steel plate and an inner box 4 made of a resin. The open / close door 10 and the drawer doors 20, 30, 40 also have the same structure as the case 2.

The refrigerating compartment 100 is provided with a shelf 102 that divides the inside into a plurality of upper and lower compartments, a chilled compartment 104 arranged at the bottom, and a plurality of trays 126 mounted inside the opening / closing door 10. The refrigerating chamber 100 has an internal temperature set to 4 ° C. and has the largest storage volume VR in the storage chamber. The chilled chamber 104 has an opening / closing door 106 and is set at -1 ° C.

Further, in the vegetable compartment 200, a storage case 202 whose peripheral side surface is substantially vertical and whose upper side is open is supported by an opening / closing mechanism 600 (see FIG. 13) of the drawer door 20 and can slide together with the drawer door. It is provided in. With this structure, by pulling out the drawer door 20, the storage case 202 can be pulled out, and the food to be stored can be taken in and out, and the storage case 202 can be removed from the drawer door 20 and cleaned.

At the rear of the upper part of the storage case 202, another storage case 204 which is interlocked with the storage case 202 or which can be independently put in and taken out when the drawer door 20 is opened is arranged. With this two-tiered structure, vertical stacking of vegetables can be reduced, freshness can be maintained, and storability can be improved. The vegetable compartment 200 has an inside temperature set to 3 ° C. and has a storage volume VV larger than that of the upper freezing compartment or the lower freezing compartment.

The freezer compartment 800, which is composed of the upper freezer compartment 300 and the lower freezer compartment 400, has an internal temperature set to −18 ° C. I have it. The upper freezer compartment 300 is provided with a storage case 302 whose peripheral side surface is substantially vertical and whose upper side is open, and which is detachably supported by the opening / closing mechanism 600 of the drawer door 30 like the storage case 202. In addition, an ice-making shelf that moves in the front-rear direction in association with the opening and closing of the drawer door 30 is provided on the upper surface of one side of the upper freezer compartment 300. The lower freezer compartment 400 is provided with a storage case 402 having an inclined rear surface and an open upper side, which is detachably supported by the opening / closing mechanism 600 of the drawer door 40, like the storage case 202.

In this embodiment, the freezer compartment 800 is vertically divided into an upper freezer compartment 300 and a lower freezer compartment 400, so that the depth of each drawer storage can be made small and the storage of stored foods can be facilitated. . Moreover, since the storage capacity is limited by the machine room 600 in which the lower freezer compartment 400 is provided at the rear, the depth of the lower freezer compartment 400 is made larger than the depth of the upper freezer compartment 300 to store the upper freezer compartment 300. Since the volume VF1 and the storage volume VF2 of the lower freezer compartment 400 are set to be approximately the same size, there is a restriction that the commonly used food is stored in the upper thin storage case 302 to improve the usability. The lower storage case 402 stores stock foods that are sometimes used to reduce usability.

In this refrigerator 1, since the refrigerator compartment 100 having a similar internal temperature is arranged above the vegetable compartment 200 and the upper freezer compartment 300 having a significantly different internal compartment temperature is arranged below the vegetable compartment 200, the heat insulation is improved. The partition wall 70 provided with the material 5 may be provided at one place between the vegetable compartment 200 and the upper freezer compartment 300, and the internal volume can be increased. Here, a partition wall 71 having a cool air ventilation passage (not shown) without a heat insulating material is provided between the refrigerating compartment 100 and the vegetable compartment 200, and a partition wall 72 is provided between the upper freezing compartment 300 and the lower freezing compartment 400. Is provided.

In this embodiment, the total storage volume V is 370 l (liter), the storage volume VR of the refrigerating compartment 100 is 200 l, the storage volume VV of the vegetable compartment 200 is 70 l, the upper freezing compartment 300 and the lower freezing compartment. The total storage volume VF of the freezer compartment 800 including the compartment 400 is set to 100 l. Here, the storage volume VF1 of the upper freezing chamber 300 and the storage volume VF2 of the lower freezing chamber 400 are set to have substantially the same size.

A machine room 500 having a compressor 502 is provided behind the lower freezing compartment 400, a heat exchanger 504 is provided behind the upper freezing compartment 300, and a fan motor 506 and a vegetable compartment 200 are provided at the lower rear of the vegetable compartment 200. A cold air distributor (cold air supply amount adjuster) 508 is arranged across the rear of the storage case 204 and the chilled chamber 104.

According to this arrangement structure, since the heavy compressor 502 is provided at the lowermost portion of the back surface, the center of gravity of the refrigerator 1 can be lowered and stabilized. In addition, since the heat exchanger 504, which is a cooling source, is arranged in a step different from that of the vegetable compartment 200 having a high inside temperature, and is placed in the vicinity of the freezing compartment 800 (upper freezing compartment 300) having the lowest inside temperature, It is possible to reduce the temperature drop inside the chamber 200 and efficiently cool the freezing chamber 800 (upper freezing chamber 300). Particularly, in the refrigerator 1 according to the present invention, since the freezer compartment 800 is arranged at the lowermost part, the heat exchanger 504 can inevitably be arranged below, so that between the machine room 500 and the heat exchanger 504. It is possible to eliminate the dead space formed in the.

Further, since the heat exchanger 504, the fan motor 506 arranged above the heat exchanger 504, and the cool air conditioner (cold air supply amount adjusting device) 508 can be lowered downward, the center of gravity of the refrigerator 1 can be lowered downward. The installability of the refrigerator 1 can be improved.

Further, since the storage case 204 of the vegetable compartment 200 (at the rear of the upper portion) is provided adjacent to the relatively thin cold air distributor 508 provided above the fan motor 506 having a slight thickness, the storage case 202 is provided. Since the storage case 204 can be further shifted and arranged rearward, the storage capacity VV of the vegetable compartment 200 can be increased while maintaining the storage space formed by a substantially vertical surface.

Further, since the cool air distributor 508 is arranged in the refrigerating compartment 100 adjacent to the chilled compartment 104 having a low inside temperature, the refrigerating compartment 100 is prevented from being over-cooled and the cool air is blown directly to the chilled compartment 104 to improve efficiency. Can be cooled well.

Next, the flow of cold air will be described with reference to FIGS. 4 to 7. First, the cool air generated in the heat exchanger 504 is blown by the fan motor 506 to the cool air distributor 508 and the freezing compartment 800 (the upper freezing compartment 300 and the lower freezing compartment 400). The cool air blown to the cool air distributor 508 is divided into the refrigerating chamber 100 and the chilled chamber 104 by the cold air distributor 508. This cold air ventilation passage structure will be described in detail with reference to FIGS. 5 and 6 together with the peripheral structure.

FIG. 5 is a front view of the refrigerating compartment 100, FIG. 6A is a partial sectional view of the refrigerating compartment 100, and FIG. 6B is a front perspective view around the chilled compartment 104.

In FIG. 5, a duct 112 having an in-compartment lighting device 108 and a cold air passage 110 is flatly attached to the center of the wall surface of the rear side inner wall of the refrigerating compartment 100. The duct 112 has a width that is half the size of the refrigerating compartment 100 and a vertical size that is as large as the height of the refrigerating compartment 100. A vertically long interior lighting device 108 is provided in the center of the duct 112. Cold air passages 110a and 110b branched from the cold air distributor 508 in a “Y” shape are provided on both sides of the lighting device 108.

The interior lighting device 108 is arranged so as to straddle a plurality of partition shelves 102, and the cooling air passages 110a and 110b are provided on the respective shelves so that cold air can reach the respective shelves of the partition shelves 102. A cold air outlet 114 is provided. With this structure, the food stored in each of the partition shelves 102 can be evenly and efficiently illuminated by the interior lighting device 108 provided at the center of the back surface.

In addition, the food stored in each of the partition shelves 102 can be efficiently cooled by blowing cold air from the two cold air vents 114 in each of the stages arranged substantially evenly on the back surface. In the interior lighting device 108, a light source 116 is provided slightly above the refrigerating compartment 100, and a transparent material 118 having a length of 422.5 mm and a width of 70 mm is provided flat in front of the light source 116. Further, the interior lighting device 108 has a light source 116 whose longitudinal direction is parallel to the wall surface and is closely arranged to reduce the depth dimension, and the translucency is provided through a reflection surface (not shown) provided on the back side thereof. It is made compact so that it can be illuminated from the material 118.

In FIG. 6, cold air is supplied to the chilled chamber 104 directly from a cold air outlet 124 provided on the front surface of the cold air distributor 508, and passes through a gap above and below the tray 122 in the chilled chamber 104. An exhaust port 125 provided below the port 124 is returned to the refrigerant circulation system. Further, a part of the cold air supplied to the chilled room 104 is supplied to the vegetable room 200.

The chilled chamber 104 is partitioned in the refrigerating chamber 100 by a transparent box 120, and by pulling out the tray 122, the opening / closing door 106 is opened in an interlocking manner. Therefore, since the exhaust port 125 can be seen through the transparent box, the exhaust port 125 is provided as low as possible so as not to be seen when the opening / closing door 10 is opened / closed.

An exhaust port 206 for exhausting cold air from the vegetable compartment 200 is provided below the front surface of the cold air distributor 508. In addition, 510 is a control box.

Returning to FIG. 4, the cold air blown from the back wall surface of the refrigerating compartment 100 cools the inside of the refrigerating compartment 100 along the arrow to reach the vegetable compartment 200 through the cold air passage provided in the partition plate 71. Be guided. Further, the cold air blown into the chilled chamber 104 is returned to the refrigerant circulation system through the upper surface and the lower surface of the tray 122, and the overcooling of the refrigerating room 100 and the vegetable room 200 is reduced. Here, in this embodiment, since an air path is formed between the chilled chamber 104 (tray 122) and the partition plate 71, the temperature inside the vegetable compartment 200 is low, without newly providing a heat insulating material. The adverse effect of the chilled chamber 104 can be reduced.

Then, the cool air guided to the vegetable compartment 200 passes through the peripheries of the storage cases 202 and 204, and then is returned from the exhaust duct 512 to the refrigerant circulation system through the exhaust port 206. The subsequent cool air passage will be described with reference to FIG.

FIG. 7 is a perspective view showing a schematic configuration of the back surface. In the figure, the cold air returned to the refrigerant circulation system in the exhaust duct 512 is guided to the drainage 514 provided below the heat exchanger 504, cooled again in the heat exchanger 504, and then guided to the fan motor 506. The drain tray 514 has a lower inclined portion and a drain hose 516 is provided at the lower end portion thereof. Therefore, the dew attached to the cooler 504 is received by the drain tray 514 and provided on the bottom surface of the refrigerator 1 (not shown). Can be led to the dew pan.

Returning to FIG. 4, on the other hand, the cool air supplied to the upper freezing compartment 300 and the lower freezing compartment 400 circulates inside and outside the storage cases 302, 402 and is returned to the drain tray 514. As described above, in the refrigerator 1 according to this embodiment, the cold air can efficiently cool the inside of the refrigerator while circulating in the distribution path.

Further, the temperature decrease due to the opening / closing of the opening / closing door 10 and the drawer doors 20, 30, 40 is detected by a sensor (not shown) provided in each storage chamber or passage, and a microcomputer (not shown) provided in the control box The cold air distributor 508 and the compressor 502 are controlled to control the temperature inside the refrigerator.

Next, referring to FIGS. 8 to 10, the usability associated with the arrangement of the refrigerating compartment 100, the vegetable compartment 200, and the freezing compartment 800 (the upper freezing compartment 300 and the lower freezing compartment 400) will be described. FIG. 8 is an installation state diagram of the refrigerator 1, FIG. 9 is an explanatory diagram showing the frequency of use of each storage room of the refrigerator, and FIG. 10 is an explanatory diagram showing the relationship between the posture of a person and the arrangement of each storage room of the refrigerator 1. .

In FIG. 8, when considering the usability of the refrigerator 1, it is necessary to consider the installation environment and the usage pattern of a person who uses the refrigerator. That is, since the refrigerator 1 is installed in the kitchen, it is necessary to consider the relationship between the refrigerator 700 (see FIG. 10), the cupboard, and the like, which are often used side by side in the kitchen, and the housing equipment.

In particular, the relationship between the refrigerator 1 and the sink 700 is important because it is frequently used as a part of cooking work. And, as a matter of course, the part-time work flow must be suitable for the usage pattern of the person using it. The refrigerator 1 according to the present embodiment is planned from the above viewpoint.

For example, when a standard Japanese woman (height 155 cm) uses the refrigerator 1 at a distance of 400 mm from the refrigerator 1, the range Y2 that can be easily reached in a standing posture is 630 mm at the lower side and 1340 mm at the upper side. . The upper part of 1340 mm is the storage range Y 1 above the shoulder. In addition, the storage range Y3 that can be easily reached when the body is in the bent posture is 310 mm in the lower part and 630 mm in the upper part. The lower part of 310 mm is a storage range Y3 that can be easily reached when crouching.

A standard female elbow height is 970 mm, and food can be easily taken in and out without raising the elbow below this position.

From these points, in view of the workability of the refrigerator 1, the storage room arranged above the elbow height of 970 mm has a good work operation in the standing posture with the opening / closing door 10. On the other hand, from the height of the elbow below 970 mm, the workability of the drawer doors 20, 30, and 40, which allows food to be taken in and out while looking over the storage chamber in any posture, is excellent.

In particular, considering the workability in the standing posture, the standard lower height of the hand of a Japanese woman is 643 mm, so the drawer placed below the elbow height of 970 mm. When the height of the door 20 from the floor surface of the drawer door 20 is 643 mm or more, food can be taken in and out in a standing posture in a comfortable posture. The height of the drawer door 20 from the floor is set further downward in the bent posture where the posture can be easily changed from the standing posture. That is, if the drawer door is provided at a position lower than the height of the elbow and within reach of the standing posture and the bending posture, food can be taken in and out easily.

The above-mentioned dimensional relations are numerical values based on a model of a standard woman, and the numerical range is, for example, considering the height of slippers normally worn in the kitchen, the coverage rate of the user, and the storage ratio. It is necessary to consider other conditions such as capacity.

When the actual usage of the refrigerator is investigated, as shown in FIG. 10, the refrigerator 1 is installed side by side with the kitchen sink 700, and is frequently used in cooking work in a standing posture. As shown in FIG. 9, the frequency of use is such that the refrigerator compartment 100, the vegetable compartment 200, the freezer compartment 800 (the upper freezer compartment 300 and the lower freezer compartment 400) continue. According to the actual use in this standing posture, by arranging the refrigerator compartment 100 in the upper part, the vegetable compartment 200 in the center, and the freezer compartment 800 (upper freezer compartment 300 and lower freezer compartment 400) in the lower part, Work movements can be made easier by reducing movements to the crouching and crouching postures.

Can be provided.

Next, the opening / closing structure of the drawer door will be described with reference to FIGS. 11 to 13. FIG. 11 is a schematic view of the opening / closing mechanism of the drawer door, FIG. 12 is an enlarged cross-sectional view of a main part of FIG. 11, and FIG. 13 is an operation comparison diagram with a conventional example of the drawer door.

11 and 12, an open / close drawer structure (opening / closing mechanism) 600 adopted by the drawer doors 20, 30, 40 will be described. The opening / closing drawer structure 600 includes a first guide rail 610 formed by being embedded in the wall surfaces on both sides of the storage chamber, and a second guide rail 620 moving on the first guide rail 610 via rollers 621. The support body 630 provided with the drawer door 20 (30, 40) that moves on the second guide rail 620 via the roller 631 and the first guide rail 610 and the second guide rail 620 are separated. The first stopper 640 for preventing the second guide rail 620 and the second stopper 641 for preventing the support body 630 from being separated from each other, and the storage case 202 (302, 402) is attached to the support body 630. It is detachably attached.

The first guide rail 610 is formed to have a U-shaped cross section, allows the roller 621 and its rotation shaft 622 to move, and has a size having a diameter of the roller 621 and an appropriate gap. To be done. The second guide rail 620 has an “L” -shaped cross-sectional shape in which the lower end portion is bent inward, the roller 621 is attached to the rear side of the outer side surface via the rotation shaft 622, and the front side of the inner side surface is formed. A roller 631 is attached to the side via a rotary shaft 632.

At least two rollers 621 and 631 are provided so that the second guide rail 620 and the support body 630 can be moved horizontally. The support 630 has an “S” -shaped cross-sectional shape, and the upper “U” -shaped portion of the “S” shape allows the roller 631 and its rotation shaft 632 to move, and the diameter of the roller 631 is It is formed in a large size with a proper gap. In this embodiment, the second guide rail 620 has an “L” shape and the support body 630 has an “S” shape, thereby increasing the rigidity of the opening / closing drawer structure 600.

The support bodies 630 provided on the left and right sides have a front portion attached to the drawer door 20 and a rear portion attached to the connecting member 650, thereby forming a “B” -shaped frame body as viewed from above, By inserting the storage case 202 into the frame body and supporting the edge body 202a of the storage case 202 with the support body 630 and the connecting member 650, the storage case 202 is detachably provided. Further, the first and second stoppers 640 and 641 are formed at the front end of the first guide rail 610 and the rear end of the support 630 so as to prevent the rollers 621 and 631 from moving. Installed.

According to the opening / closing drawer structure 600, the second guide rail 620 serves as an intermediate connecting member between the first guide rail 610 and the support body 630, so that the storage case 202 attached to the support body 630 is attached to the storage case 202. Since it can be pulled out largely forward while maintaining the horizontal position, the entire storage case 202 can be seen from above and food can be easily taken in and out.

At this time, the rollers 621 and 631 are prevented from moving by the stoppers 640 and 641 when the opening / closing drawer structure 600 is pulled out to the maximum extent, so that the drawer door 20 is prevented from falling due to being pulled out too much. You can Further, since the storage case 202 is largely pulled out forward, the storage case 202 can be easily removed, so that the storage case 202 can be easily cleaned.

On the other hand, in the housed state, the first and second guide rails 610 and 620 and the support 630 form a triple stack and are housed compactly.

In FIG. 13, according to the opening / closing drawer structure 600 according to the present embodiment shown in FIG. 13A, the weights of the storage case 202 and the stored items are distributed by the first guide rails 610 on both sides. Can be supported. Therefore, even if the drawer door 20 is pulled out, the center of gravity G of the storage case 202 only slides forward. Therefore, the weight of the moved center of gravity G is evenly distributed by the legs (not shown) provided at the front part of the bottom surface of the housing 2. You can support it.

Furthermore, since the first guide rail 610 can be embedded in both wall surfaces of the storage chamber and a storage case having almost the same size as the storage chamber can be employed, dead space can be reduced and efficient storage can be achieved. Can be achieved.

On the other hand, in the conventional example including the opening / closing door 650 and the rotating storage case 651 shown in FIG. 13B, when the rotating door 650 and the storage case 651 are opened, the center of gravity G moves diagonally forward. To do. Moreover, since all of these weights are applied to one hinge part and one leg part, the hinge part is upsized and the balance of the entire refrigerator is lost.

Further, in this structure, due to the presence of the opening / closing door 650, there is no choice but to put in and take out food from the left side in the drawing, and the workability of taking in and out food is poor as compared with the drawer door. Furthermore, in this embodiment, since a dead space is created because the storage case 651 is pulled out, efficient storage cannot be achieved.

Next, each storage chamber will be described in detail with reference to FIGS. 2 and 14 to 21. Since the specific size of each storage chamber has been shown above, description thereof will be omitted.

In FIG. 2, the refrigerating compartment 100 is provided with a thin transparent shelf 102 fixed to the upper stage of the refrigerator and transparent variable shelves 124 arranged side by side in the middle stage.
