[0011] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[0012] <First embodiment> (Overall configuration of refrigerator) First, the overall configuration of a refrigerator 1 according to the first embodiment will be described. Fig. 1 shows the external appearance of the refrigerator 1 as seen from the front.

[0013] The exterior of the refrigerator 1 is mainly composed of an insulated box 50. This insulated box 50 forms the storage space of the refrigerator 1. The storage space formed by the insulated box 50 is divided by a plurality of horizontally extending partitions into, for example, from the top, a refrigerator compartment 11, a vegetable compartment (a drawer-type storage compartment) 12, an ice-making compartment and a second freezer compartment, and a freezer compartment.

[0014] The refrigerator compartment 11 is provided with refrigerator compartment doors 11a and 11b that open like a double door divided into left and right halves. The vegetable compartment 12 is provided with a pull-out vegetable compartment door 12a. The freezer compartment is provided with a pull-out freezer compartment door 13a. The ice-making compartment is provided with a pull-out ice-making compartment door 14a. The second freezer compartment is provided with a pull-out freezer compartment door 15a.

[0015] As described above, the refrigerator 1 according to the present embodiment is divided into a plurality of storage spaces, and includes the refrigerator compartment 11 and the vegetable compartment 12. However, the locations of the storage spaces are not limited to the above. Furthermore, the configuration of the doors provided in the storage spaces is not limited to the above.

[0016] In this embodiment, the surface on which the door is provided is called the front or front surface of the refrigerator. Based on the front surface, the surfaces of the refrigerator 1 are called the top, side, back, and bottom surfaces based on the positions of the refrigerator 1 when it is installed in a normal state. In addition, the left-right direction (horizontal direction perpendicular to the up-down direction) when the refrigerator 1 is placed on the installation surface is called the left-right direction of the refrigerator 1 (or the vegetable compartment 12, etc.). In addition, the up-down direction (vertical direction perpendicular to the left-right direction) when the refrigerator 1 is placed on the installation surface is called the up-down direction of the refrigerator 1 (or the vegetable compartment 12, etc.). In addition, the side located on the left side when viewed from the front side of the refrigerator 1 is called the left side of the refrigerator 1, and the side located on the right side when viewed from the front side of the refrigerator 1 is called the right side of the refrigerator 1.

[0017] (Vegetable compartment configuration) Next, a more detailed configuration of the vegetable compartment 12 provided in the refrigerator 1 will be described. Fig. 2 shows the appearance of the vegetable compartment 12 as seen from the front. Fig. 3 shows the internal configuration of the vegetable compartment 12. Fig. 3 shows a cross-sectional configuration of the vegetable compartment 12 taken along line AA in Fig. 2. Fig. 4 shows the side configuration of the vegetable compartment 12. Figs. 5 and 6 are perspective views showing the interior of the vegetable compartment 12. Figs. 3 and 5 show the vegetable compartment door 12a in a closed state. Figs. 4 and 6 show the vegetable compartment door 12a in a pulled-out state.

[0018] The vegetable compartment 12 mainly includes a pull-out vegetable compartment door 12a, a main body case 20, a case support portion 21, and an upper case 80.

[0019] The vegetable compartment door 12a is disposed at the front of the vegetable compartment 12 and is configured so as to be able to be pulled out towards the front.

[0020] The main body case 20 is disposed on the rear surface of the vegetable compartment door 12a. More specifically, the main body case 20 is supported by a case support portion 21 attached to the rear surface of the vegetable compartment door 12a.

[0021] The case support part 21 is formed of a rigid material such as metal. The case support part 21 is attached to the back surface of the vegetable compartment door 12a and extends in the front-rear direction along the side surface of the refrigerator 1. In this embodiment, two case support parts 21 are provided, one of which is attached near the right end of the back surface of the vegetable compartment door 12a, and the other is attached near the left end of the back surface of the vegetable compartment door 12a.

[0022] A movable roller (sliding portion) 22 is provided at the rear end of the case support portion 21. When the vegetable compartment door 12a is housed in the refrigerator 1, the movable roller 22 abuts against a rail (not shown) formed on the inner wall of the insulated box body 50. When the vegetable compartment door 12a is pulled out from the refrigerator 1, the movable roller 22 slides on the rail while abutting against the bottom surface of the rail.

[0023] With the above configuration, when the vegetable compartment door 12a is pulled out toward the front and opened, the main body case 20 supported by the case support portion 21 is pulled out together with the door 12a, as shown in Fig. 6. This allows the user to take out items stored in the main body case 20 of the vegetable compartment 12.

[0024] The upper case 80 is disposed on the upper side of the vegetable compartment 12. The upper case 80 has a generally rectangular box shape in top view. The upper case 80 has a size (plan area) of about 2 / 3 of the size (plan area) of the upper part of the main body case 20 in top view, and covers the upper central part to the rear part of the main body case 20 (see FIG. 5). Sliders 81 are provided on both the left and right side surfaces of the upper case 80, and are slidably supported on the upper edges of both side surfaces of the main body case 20. Stoppers 82 are provided on the upper edges of both side surfaces of the main body case 20, and by engaging with protrusions (not shown) extending downward from the slide parts 81, the upper case 80 moves together with the main body case 20 in conjunction with the opening and closing of the door 12a.

[0025] Upper case 80 can be used, for example, as a fruit case for storing fruits, etc. Upper case 80 may have two storage spaces divided into left and right as shown in Fig. 5 and the like.

[0026] A second rail (not shown) is formed on the inner wall of the heat-insulating box 50, and when the upper case 80 is pushed inward with the main case 20 pulled out toward the front, the sliding portion 81 of the upper case 80 slides on the second rail to support the upper case 80. This allows the user to push the upper case 80 inward to take out items stored behind the main case 20. When the vegetable compartment door 12a is closed with the upper case 80 pushed inward, the stopper 82 of the main case 20 engages again with the protrusion of the sliding portion 81 of the upper case 80. This allows the upper case 80 to move together with the main case 20 in conjunction with the opening and closing of the door 12a.

[0027] In this manner, the vegetable compartment 12, which is an example of a drawer-type storage compartment, is mainly formed by the drawer-type door 12a, the main body case 20, and the upper case 80.

[0028] The main body case 20 has a box-like shape. The main body case 20 mainly has a front part 20a, left and right side parts 20b, a rear part 20c, a main bottom part (rear bottom part) 20d, and a front bottom part 25. The names of these parts of the main body case 20 are determined based on the positions of the main body case 20 when it is accommodated in the refrigerator 1.

[0029] The inner wall (front inner wall) of the front portion 20a has a wave-shaped shape 24. This wave-shaped shape 24 is an uneven shape with multiple curved recesses. By making the recesses a curved surface, it is possible to support objects of various sizes in the lateral direction. In addition, by making the surface curved, it is possible to support the object without applying local pressure, and leafy vegetables (specifically, spinach, Chinese cabbage, Japanese mustard spinach, etc.) can be stored without damaging them. The width (width in the left-right direction) of one curved recess can be determined according to the size of, for example, a beverage bottle (specifically, a PET bottle of about 2 liters, a one-sho bottle, etc.) and leafy vegetables. Specifically, the width of one curved recess can be set within a range of, for example, 7 cm to 20 cm.

[0030] 3 and the like, the upper side of the front surface 20a is slightly inclined toward the front. In line with this inclination, the upper side of the inner wall of the front surface 20a having the corrugated shape 24 is also inclined toward the front. As a result, since the upper side of an item placed on the front side of the main body case 20 is inclined toward the front, it is possible to make it easy to take out the item placed on the front side of the main body case 20.

[0031] The upper side of the rear surface 20c of the main body case 20 is inclined backward. The upper end of the rear surface 20c is located at approximately the same position as the rear surface of the upper case 80 when the vegetable compartment door 12a is closed (see FIG. 3).

[0032] The bottom surface of the main case 20 is mainly formed by a main bottom surface portion 20d and a front bottom surface portion 25. The main bottom surface portion 20d is mainly formed in an area facing the upper case 80 in the vertical direction. The front bottom surface portion 25 is located on the front side of the main bottom surface portion 20d, and its front end portion is connected to the front surface portion 20a.

[0033] A step 26 is provided between the front bottom surface portion 25 and the main bottom surface portion 20d. This allows the interior of the main body case 20 to be simply divided into sections with the step 26 as a boundary.

[0034] 3, the front bottom surface portion 25 is inclined downward toward the front. On the other hand, the main bottom surface portion 20d extends substantially horizontally in the front-rear direction.

[0035] Because the front bottom surface portion 25 is inclined downward toward the front, items to be placed on the front side of the main body case 20 can be placed by leaning them against the front side (i.e., the front inner wall portion having the corrugated shape 24).

[0036] 3 and 5, the upper case 80 is engaged so that the front portion 80a of the upper case 80 is positioned at a distance from the inner wall portion having the corrugated shape 24 of the front portion 20a on the rear side of the front portion 20a of the main case 20. As a result, the upper portion 80 is not present in the upper portion of the front side of the main case 20 formed by the front bottom portion 25 and the front portion 20a, and the upper side of the case is open. Therefore, taller items can be stored on the front side of the main case 20 compared to the rear side of the main case 20.

[0037] (Summary of the first embodiment) As described above, the refrigerator 1 according to this embodiment is equipped with a drawer-type storage compartment such as the vegetable compartment 12. The vegetable compartment 12 is equipped with a main body case 20. The main body case 20 has a front portion 20a (front inner wall portion) having an uneven shape such as a corrugated shape 24 on the inside surface. The upper side of this front portion 20a is inclined toward the front. The main body case 20 also has a front bottom surface portion 25 that is inclined downward toward the front.

[0038] Providing unevenness on the inner surface of the front portion 20a makes it possible to absorb lateral shaking of items stored on the front portion 20a side of the main body case 20. Therefore, it is possible to prevent items stored on the front portion 20a side of the main body case 20 from falling over due to vibration of the main body case 20 that may occur when, for example, the vegetable compartment door 12a is pulled out.

[0039] In addition, since the upper side of the front surface 20a of the main body case 20 is inclined toward the front and the front bottom surface 25 of the main body case 20 is inclined downward toward the front, an item placed on the front side of the main body case 20 can be placed so as to lean against the inner wall surface of the front surface 20a. This allows the item to be supported by the uneven shape provided on the inner wall surface of the front surface 20a, effectively preventing the item from falling sideways due to vibration of the main body case 20. Therefore, for example, a vertically long beverage container such as a plastic bottle can be placed in a stable state.

[0040] In addition, according to the above configuration, leafy vegetables such as spinach, Chinese cabbage, and Japanese mustard spinach can be stably held in a vertically arranged state, thereby preventing the loss of freshness of the leafy vegetables.

[0041] Furthermore, according to the above configuration, the upper side of an item placed on the front side of main body case 20 is inclined toward the front in accordance with the inclination of front surface portion 20a and front bottom surface portion 25, making it easy to take out items placed on the front side of main body case 20.

[0042] As described above, the refrigerator 1 according to this embodiment can prevent items stored in the vegetable compartment 12 from tipping over without adding any additional parts. Therefore, items that are long, such as beverage containers and leafy vegetables, can be stored in a stable state by preventing them from tipping over sideways.

[0043] In this embodiment, the vegetable compartment 12 is given as an example of a drawer-type storage compartment, but the drawer-type storage compartment is not limited to the vegetable compartment. In another embodiment of the present invention, the drawer-type storage compartment may be, for example, a freezer compartment, a chilled compartment, or the like.

[0044] <Second embodiment> Next, a second embodiment of the present invention will be described. In the second embodiment, the configuration of the vegetable compartment is different from that of the first embodiment. For the other configurations, the same configuration as in the first embodiment can be applied.

[0045] As in the first embodiment, the vegetable compartment 12 of the refrigerator 1 according to this embodiment mainly includes a drawer-type vegetable compartment door 12a, a main body case 20, a case support portion 21, and an upper case 80. The vegetable compartment door 12a, the case support portion 21, and the upper case 80 can have the same configuration as in the first embodiment.

[0046] As in the first embodiment, the main body case 20 has a box-like shape mainly formed by a front portion 20a, left and right side portions 20b, a rear portion 20c, a main bottom portion (rear bottom portion) 20d, and a front bottom portion 25.

[0047] In the first embodiment, the inner wall (front inner wall) of the front surface 20a is configured with a wall surface having a wave shape 24. In contrast to this, in the present embodiment, the inner wall (front inner wall) of the front surface 20a is provided with a plurality of protrusions such as ribs. For example, the ribs are formed of plate-like members protruding approximately perpendicularly to the inner wall surface of the front surface 20a. In this way, an uneven shape is formed on the inner wall (front inner wall) of the front surface 20a.

[0048] The spacing between the multiple ribs can be determined according to the size of beverage bottles (specifically, about 2-liter plastic bottles, 1.8L bottles, etc.) and leafy vegetables (specifically, spinach, Chinese cabbage, Japanese mustard spinach, etc.) Specifically, the spacing between the multiple ribs can be within the range of, for example, 7 cm to 20 cm.

[0049] As in the first embodiment, the upper side of the front surface portion 20a is slightly inclined toward the front. Along with this inclination, the upper side of the inner wall of the front surface portion 20a, which has multiple ribs, is also inclined toward the front. In addition, the front bottom surface portion 25 is inclined downward toward the front.

[0050] According to the above configuration, since the upper side of an item placed on the front side of the main body case 20 is inclined toward the front, it is possible to make it easy to take out the item placed on the front side of the main body case 20.

[0051] In addition, the inner wall of the front portion 20a is provided with an uneven shape by a plurality of ribs or the like. Therefore, by arranging items at a slight incline against this wall, vertically long items such as beverage containers and leafy vegetables can be prevented from falling sideways and can be arranged in a more stable state. Therefore, the refrigerator 1 can be obtained which can prevent items stored in the vegetable compartment 12 from falling over.

[0052] <Third embodiment> Next, a third embodiment of the present invention will be described. In the third embodiment, the configuration of the vegetable compartment is different from that of the first embodiment. For the other configurations, the same configuration as in the first embodiment can be applied.

[0053] As in the first embodiment, the vegetable compartment 12 of the refrigerator 1 according to this embodiment mainly includes a drawer-type vegetable compartment door 12a, a main body case 20, a case support portion 21, and an upper case 80. The vegetable compartment door 12a, the case support portion 21, and the upper case 80 can have the same configuration as in the first embodiment.

[0054] As in the first embodiment, the main body case 20 has a box-like shape mainly formed by a front portion 20a, left and right side portions 20b, a rear portion 20c, a main bottom portion (rear bottom portion) 20d, and a front bottom portion 25.

[0055] In the first embodiment, the front bottom surface portion 25 is inclined downward toward the front. In contrast, in this embodiment, the front bottom surface portion 25 extends in a substantially horizontal direction without inclining in the front-rear direction. The front bottom surface portion 25 may be integral with (i.e., flush with) the main bottom surface portion 20d. In another embodiment, the front bottom surface portion 25 and the main bottom surface portion 20d may be formed by different surfaces, and a step 26 may be provided between them.

[0056] On the other hand, the front surface 20a has a slight upper inclination toward the front, as in the first embodiment, and the inner wall of the front surface 20a, which has multiple ribs, also has an upper inclination toward the front.

[0057] The inner wall (front inner wall) of the front surface portion 20a has an uneven shape. This uneven shape may be a wave shape 24 similar to the first embodiment, or may be formed of a plurality of protrusions (e.g., ribs, etc.) similar to the second embodiment.

[0058] According to the above configuration, an item placed on the front side of the main body case 20 has its upper side inclined toward the front in line with the inclination of the front portion 20a, making it easy to take out the item placed on the front side of the main body case 20.

[0059] In addition, since the inner wall of the front portion 20a is provided with an uneven shape, items can be arranged at a slight incline relative to this wall, which prevents vertically long items such as beverage containers and leafy vegetables from tipping over and allows them to be arranged in a more stable state. This results in a refrigerator 1 that can prevent items stored in the vegetable compartment 12 from tipping over.

[0060] <Fourth embodiment> Next, a fourth embodiment of the present invention will be described. In the fourth embodiment, the configuration of the vegetable compartment is different from that of the first embodiment. For the other configurations, the same configuration as in the first embodiment can be applied.

[0061] As in the first embodiment, the vegetable compartment 12 of the refrigerator 1 according to this embodiment mainly includes a drawer-type vegetable compartment door 12a, a main body case 20, a case support portion 21, and an upper case 80. The vegetable compartment door 12a, the case support portion 21, and the upper case 80 can have the same configuration as in the first embodiment.

[0062] As in the first embodiment, the main body case 20 has a box-like shape mainly formed by a front portion 20a, left and right side portions 20b, a rear portion 20c, a main bottom portion (rear bottom portion) 20d, and a front bottom portion 25.

[0063] In the first embodiment, the upper side of the front surface 20a is slightly inclined toward the front, whereas in the present embodiment, the front surface 20a extends substantially vertically in the up-down direction without being inclined.

[0064] On the other hand, the front bottom surface portion 25 is inclined downward toward the front, similarly to the first embodiment, and a step 26 is provided between the front bottom surface portion 25 and the main bottom surface portion 20d.

[0065] The inner wall (front inner wall) of the front surface portion 20a has an uneven shape. This uneven shape may be a wave shape 24 similar to the first embodiment, or may be formed of a plurality of protrusions (e.g., ribs, etc.) similar to the second embodiment.

[0066] According to the above configuration, the upper side of an item placed on the front side of the main body case 20 is inclined toward the front in accordance with the inclination of the front bottom surface portion 25, making it easy to take out the item placed on the front side of the main body case 20.

[0067] In addition, since the inner wall of the front portion 20a is provided with an uneven shape, items can be arranged at a slight incline relative to this wall, which prevents vertically long items such as beverage containers and leafy vegetables from tipping over and allows them to be arranged in a more stable state. This results in a refrigerator 1 that can prevent items stored in the vegetable compartment 12 from tipping over.
