Description

[Technical field]

[0001] The present disclosure relates to a partition structure for a refrigerator. [Background technology]

[0002] Conventional refrigerators are provided with multiple storage compartments inside the box, and the multiple storage compartments include, for example, a refrigerator compartment controlled to be in a refrigeration temperature range, a freezer compartment controlled to be in a freezing temperature range, and a vegetable compartment controlled to be in a vegetable compartment temperature range. In this way, the internal space of each storage compartment is set to a different temperature range according to the food to be stored, and there are refrigerators with the same capacity range in which the vegetable compartment, freezer compartment, etc. are located differently inside the box in response to the needs of users.

[0003] In addition, in a refrigerator having a plurality of storage compartments inside the box, since different foods are stored in each storage compartment, there is an appropriate front height and set temperature for each storage compartment. Therefore, when manufacturing a refrigerator in which the arrangement of each storage compartment inside the box differs from the conventional one, it is necessary to change the structure for attaching the partitions inside the inner box in order to attach plate-shaped partitions inside the box according to the arrangement of each storage compartment, and it is common to form the boxes individually.

[0004] In this way, by providing a plurality of models of refrigerators in which the boxes are individually formed and the storage compartments, each controlled to a different temperature range, are arranged in different positions, it is possible to expand the choices available to consumers. However, on the other hand, even for refrigerators of the same capacity range, the appropriate front height of the storage compartments is different, so the manufacturer must change the mounting positions of the partitions to be mounted inside the box body, and a different mold is required for each inner box with a changed mounting position, which results in the need to manufacture a plurality of molds, resulting in high costs.

[0005] In order to reduce the manufacturing costs of refrigerators that arise from changing the arrangement of storage compartments and to improve user convenience, there are refrigerators that allow the user to freely set the storage compartments with multiple drawer doors to either refrigerator compartments or freezer compartments (see, for example, Patent Document 1).

[0006] In Patent Document 1, the refrigerator has multiple drawer doors that allow the user to freely set the storage compartments as either refrigerator compartments or freezer compartments, making it possible to provide refrigerators with the same capacity but with different layouts of storage compartments inside the box. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 6655747 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in the refrigerator of Patent Document 1, the temperature of each storage compartment is switched with the frontage height of each storage compartment fixed, so it is not possible to ensure an appropriate frontage for the storage compartment for each size of food being stored, which may reduce usability for the user.

[0009] The present disclosure has been made to solve the above problems, and has an object to provide a refrigerator that is easy to use for users while reducing manufacturing costs. [Means for solving the problem]

[0010] The refrigerator according to the present disclosure comprises an outer box constituting an outer shell, an inner box arranged to form a first space between the outer box and the inner box and having an injection opening for injecting an insulating material, and the insulating material filled in the first space, and a box body having a storage space for storing food therein, a partition having a second space formed therein and a partition opening formed on a side surface, the partition having a partition body dividing the storage space into a plurality of storage compartments with different temperature zones, and a locking portion for fixing the partition body to the inner box, and the inner box is provided with a partition member having a second space formed therein and a partition opening formed on a side surface, the partition body having a second space formed therein and a partition opening formed on a side surface, the partition body dividing the storage space into a plurality of storage compartments with different temperature zones, and a locking portion for fixing the partition body to the inner box, and the inner box is provided with a locking portion for locking the partition body to the inner box. the partition body has an attachment portion to which the locking portion is attached, the attachment portion has an attachment portion opening formed on a surface of the partition body facing the side surface when the locking portion is attached to the attachment portion and the partition body is fixed to the inner box, the attachment portion opening communicates with the first space, and the partition body can be attached to the inner box at a position where the attachment portion opening and the partition opening overlap above the attachment portion opening or at a position where the attachment portion opening and the partition opening overlap below the attachment portion opening, when viewed from the side of the inner box. The partitions having different positions of the partition body relative to the inner box can be selectively attached to the common attachment portion. . Effect of the Invention

[0011] According to the refrigerator of the present disclosure, the partition body can be attached to the inner box at a position where the mounting opening and the partition opening overlap above the mounting opening or at a position where the mounting opening and the partition opening overlap below the mounting opening, when the inner box is viewed from the side. Therefore, the vertical position of the partition body changes when the partition body is attached at a position where the mounting opening and the partition opening overlap above the mounting opening and when the partition body is attached at a position where the mounting opening and the partition opening overlap below the mounting opening. In either case, since the mounting opening and the partition opening overlap, the insulating material injected into the first space from the injection opening can be injected into the second space of the partition body through the mounting opening and the partition opening communicating with the first space. In this way, the mounting position of the partition body attached to the box body can be changed, so that an appropriate opening can be secured for each storage chamber, improving usability for the user. In addition, since the mounting position of the partition body inside the box can be changed, and the insulating material injected into the first space from the injection opening can be injected into the second space of the partition body regardless of the mounting position of the partition body inside the box, manufacturing costs can be reduced. In other words, usability for users can be improved while reducing manufacturing costs. [Brief description of the drawings]

[0022] FIG. 6 is a diagram showing refrigerant circuits 103 of refrigerators 100 and 200 according to the embodiment. FIG. 7 is a connection diagram of refrigerant piping inside refrigerator 100 according to the embodiment. FIG. 8 is a connection diagram of refrigerant piping according to a modified example of the inside of refrigerator 100 according to the embodiment. Since the configuration of refrigerant circuit 103 is the same for refrigerators 100 and 200, refrigerator 100 will be taken as an example for explanation. Arrows shown in FIG. 6 indicate the flow of refrigerant. In FIG. 7 and FIG. 8, the diagonally lower right direction indicated by the outline arrow is the front side of refrigerator 100.

[0023] Refrigerator 100 according to the embodiment includes refrigerant circuit 103 in which refrigerant circulates. As shown in Fig. 6, refrigerant circuit 103 includes compressor 8, fin-tube type machine room condenser 9, left side surface condensation pipe 10, ceiling surface condensation pipe 11, rear surface condensation pipe 12, right side surface condensation pipe 13, dew formation prevention pipe 14, dryer 15, capillary tube 16 as a pressure reducing device, cooler 17, muffler (liquid reservoir) 18, and suction pipe 19. Here, machine room condenser 9, left side surface condensation pipe 10, ceiling surface condensation pipe 11, rear surface condensation pipe 12, right side surface condensation pipe 13, and dew formation prevention pipe 14 are condensation system pipes.

[0024] As shown in FIG. 7, the compressor 8, the machine room condenser 9, and the dryer 15 are installed in a machine room 21 provided at the lower part of the rear side of the refrigerator 100. A part of the left side condensation pipe 10 provided inside the left side plate constituting the left side surface of the box body 101 extends to the ceiling surface side and is connected to the ceiling surface condensation pipe 11 provided inside the ceiling plate constituting the ceiling surface. Instead of the left side condensation pipe 10 and the ceiling surface condensation pipe 11 being connected, a part of the right side condensation pipe 13 provided inside the right side plate constituting the right side surface of the box body 101 may extend to the ceiling surface side and be connected to the ceiling surface condensation pipe 11. The left side condensation pipe 10, the ceiling surface condensation pipe 11, the rear condensation pipe 12, and the right side condensation pipe 13 are fixed to the inner surface of the metal outer box 22 of the refrigerator 100 with aluminum tape, although not shown.

[0025] Further, the refrigerator 100 is provided with a machine room cooling fan (not shown) that is provided in the machine room 21 and cools the machine room condenser 9 and the compressor 8.

[0026] Two capillary tubes 16 or multiple coolers 17 may be installed downstream of the dew prevention piping 14 after passing through the condensation system piping. When two capillary tubes 16 are installed, a three-way valve is installed upstream of the capillary tubes 16. Also, the machine room condenser 9, ceiling surface condensation piping 11, and rear surface condensation piping 12 do not have to be installed if the condensation capacity can be obtained with only the left side surface condensation piping 10 and the right side surface condensation piping 13.

[0027] 7, dew prevention piping 14 is arranged on front flange portion 24 so as to surround each storage compartment, i.e., refrigerator compartment 1, ice-making compartment 2, small freezer compartment 3, freezer compartment 4, and vegetable compartment 5. In addition, dew prevention piping 14 is connected to right side condensation piping 13 at the lower right rear side, and is connected to dryer 15 arranged in machine compartment 21 at the lower left rear side.

[0028] When the insulation performance between the wall surface of the refrigerator compartment 1 and the outer box 22 is good, the dew prevention piping 14 may be arranged on the front flange portion 24 so as to surround each storage compartment except for the refrigerator compartment 1, as shown in Fig. 8. In other words, the dew prevention piping 14 does not have to be arranged on the upper side and the left and right front flange portions 24 of the refrigerator compartment 1. Here, cases where the insulation performance between the wall surface of the refrigerator compartment 1 and the outer box 22 is good include cases where the distance between the wall surface of the refrigerator compartment 1 and the outer box 22, i.e., the insulation thickness, is large, or cases where a vacuum insulation material is arranged between the wall surface of the refrigerator compartment 1 and the outer box 22.

[0029] In the refrigerator 100, the cold air produced by cooling the air in the cooling compartment 39 by the refrigerant circuit 103 is blown by the cooling fan 25 provided above the cooler 17 as shown in FIG. 4. The blown cold air is supplied to the freezer compartment 4, the ice making compartment 2, the small freezer compartment 3, and the refrigerator compartment 1 through the duct 26 on the back of the refrigerator 100. Return cold air from the refrigerator compartment 1 is supplied to the vegetable compartment 5 through a refrigerator compartment intermediate air duct (not shown). The cold air supplied to the vegetable compartment 5 is returned to the cooler 17 through a return duct (not shown). The temperature of each storage compartment is detected by a thermistor installed in each storage compartment, and is controlled by adjusting the opening degree of the damper (not shown) installed in each storage compartment, the output of the compressor 8, the airflow rate of the cooling fan 25, and the like so as to reach a preset temperature.

[0030] In addition, in the refrigerator 200, the cold air produced by cooling the air in the cooling compartment 39 by the refrigerant circuit 103 is blown by the cooling fan 25 provided above the cooler 17 as shown in FIG. 5. The blown cold air is supplied to the freezer compartment 4, the ice-making compartment 2, the small freezer compartment 3, and the refrigerator compartment 1 through the duct 26 on the back of the refrigerator 200. Return cold air from the refrigerator compartment 1 is supplied to the vegetable compartment 5 through a refrigerator compartment return air duct (not shown). The cold air supplied to the vegetable compartment 5 is returned to the cooler 17 through a return duct (not shown). In the refrigerator 200, since the cooler 17 is provided on the back of the vegetable compartment 5, a heat insulating material 28 is provided between the vegetable compartment 5 and the cooler 17 to insulate them. The heat insulating material 28 may include a vacuum heat insulating material. The temperature of each storage compartment is detected by a thermistor installed in each storage compartment, and is controlled by adjusting the opening of a damper (not shown) installed in each storage compartment, the output of compressor 8, the airflow rate of cooling fan 25, etc. so as to reach a preset temperature.

[0031] The refrigerator 100 and the refrigerator 200 are provided with an inner box 29 indicated by a thick line in Fig. 4 and Fig. 5, and the inner box 29 is configured to have a common shape in the refrigerator 100 and the refrigerator 200. In the refrigerator 100 and the refrigerator 200, the types of the storage compartments of the refrigerator compartment 1, the ice making compartment 2, the small freezer compartment 3, the freezer compartment 4, and the vegetable compartment 5 are the same, and the vegetable compartment 5 is arranged at the lowest level in the refrigerator 100, and the freezer compartment 4 is arranged at the lowest level in the refrigerator 200. The vegetable compartment 5 and the freezer compartment 4 have different vertical widths of the front openings. Therefore, partitions 27a and 27b are provided between the vegetable compartment 5 and the freezer compartment 4 to separate the vegetable compartment 5 and the freezer compartment 4, and the vertical positions at which the partitions 27a and 27b are provided are different between the refrigerator 100 and the refrigerator 200.

[0032] FIG. 9 is a perspective view of the lower part of the inner box 29 to which the partitions 27a and 27b of the refrigerators 100 and 200 according to the embodiment are attached. FIG. 10 is an enlarged view of the region C of the inner box 29 shown in FIG. 9. FIG. 11 is a side view of the periphery of the recess of the inner box 29 of the refrigerators 100 and 200 according to the embodiment. As shown in FIG. 10, a recess 30 is formed on the left side surface 29a of the inner box 29 at a position where the partitions 27a and 27b are attached, the recess 30 being recessed toward the outside of the inner box 29 (to the left in the left side surface 29a when the inner box 29 is viewed from the front). The recess 30 extends rearward from the opening of the inner box 29 in a substantially horizontal direction and is formed with a certain width in the upper and lower directions, and the upper and lower boundaries of the recess 30 are formed by a protrusion protruding toward the inside of the refrigerator. The protrusion above the recess 30 is referred to as an upper protrusion 31, and the protrusion below the recess 30 is referred to as a lower protrusion 32. As shown in Fig. 11, the recess 30 is formed with a plurality of mounting openings 33 (33a to 33c) for injecting the urethane foam 23 into the insides of the partitions 27a and 27b. These mounting openings 33 communicate with an internal space 44 (see Figs. 4 and 5). The recess 30, the upper protrusion 31, and the lower protrusion 32 formed on the left side surface 29a of the inner box 29 form a mounting portion 34a for mounting the partitions 27a and 27b to the inner box 29. Upper flanges 35a, 40a and lower flanges 36a, 41a of the partitions 27a and 27b, which will be described later, are pushed into the rear of the inner box 29 between the upper protrusion 31 and the lower protrusion 32 so as to slide along the side surface of the recess 30. By doing so, the upper flanges 35a, 40a and the lower flanges 36a, 41a of the partitions 27a, 27b are sandwiched between the upper convex portion 31 and the lower convex portion 32, and the partitions 27a, 27b are attached to the inner box 29. Although not shown, an attachment portion 34b having a similar configuration to the attachment portion 34a is also formed on the right side surface 29b of the inner box 29 at approximately the same height as the attachment portion 34a.

[0033] Fig. 12 is an overall perspective view of partition 27a attached to attachment parts 34a, 34b of inner box 29 of refrigerator 100 according to the embodiment. Fig. 13 is an overall perspective view of partition 27b attached to attachment parts 34a, 34b of inner box 29 of refrigerator 200 according to the embodiment. Fig. 14 is an enlarged perspective view of left front part D1 of partition 27a shown in Fig. 12. Fig. 15 is an enlarged perspective view of left front part D2 of partition 27b shown in Fig. 13.

[0034] The partition 27a (hereinafter also referred to as the first partition) is a partition used in the refrigerator 100 of model A. As shown in Fig. 12, Fig. 14, and Fig. 22 described later, the partition 27a is composed of a plate-shaped partition body 37a having an internal space 37aa (hereinafter also referred to as the second space), a left side surface portion 38a forming the left side surface of the partition body 37a, a right side surface portion 42a forming the right side surface of the partition body 37a, upper flanges 35a, 40a, and lower flanges 36a, 41a. The partition 27b (hereinafter also referred to as the second partition) is a partition used in the refrigerator 200 of model B. As shown in Fig. 13, Fig. 15, and Fig. 23 described later, the partition 27b is composed of a plate-shaped partition body 37b having an internal space 37ba (hereinafter also referred to as a second space), a left side surface portion 38b forming the left side surface of the partition body 37b, a right side surface portion 42b forming the right side surface of the partition body 37b, upper flanges 35b, 40b, and lower flanges 36b, 41b. The partition 27a includes upper flanges 35a, 40a extending above the left and right side surfaces, and lower flanges 36a, 41a extending below the left and right side surfaces as locking portions. Similarly, the partition 27b includes upper flanges 35b, 40b extending above the left and right side surfaces, and lower flanges 36b, 41b extending below the left and right side surfaces as locking portions. Partition 27a is fixed to upper flanges 35a, 40a and lower flanges 36a, 41a of inner box 29 from the back side of inner box 29 with screws (not shown). Partition 27b is fixed to upper flanges 35b, 40b and lower flanges 36b, 41b of inner box 29 from the back side of inner box 29 with screws (not shown). Fixing partitions 27a, 27b in this manner suppresses outflow of urethane foam 23 from between partition 27a and inner box 29 or between partition 27b and inner box 29.

[0035] Fig. 16 is a vertical cross-sectional view of the vegetable compartment 5 and its surroundings in a state where the partition 27a is attached to the inner box 29 of the refrigerator 100 according to the embodiment. Fig. 17 is a schematic diagram in which the region F of the inner box 29 and the partition 27a shown in Fig. 16 is enlarged. Fig. 16 shows a vertical cross-section along the left-right direction in a schematic manner, and the dashed lines show the attachment parts 34a and 34b. Fig. 16 also shows the vegetable compartment 5 at the bottom of the refrigerator 100. Fig. 17 also shows a path along which the urethane foam 23 injected from an injection opening (not shown) provided on the back surface of the inner box 29 of the box body 101 flows into the internal space 44 of the box body 101, and the arrows show the flow of the urethane foam 23.

[0036] The internal spaces of the partition bodies 37a, 37b of the partitions 27a, 27b are filled with urethane foam 23 as a heat insulating material. As shown in Fig. 16 and Fig. 17, when manufacturing the refrigerator 100, after the partition 27a is attached to the inner box 29 of the box body 101, the urethane foam 23 is injected from the injection opening on the back surface of the inner box 29 of the box body 101 into the internal space 44 (see Fig. 4 and Fig. 5) of the box body 101, and the urethane foam 23 is filled into the internal space 37aa of the partition body 37a of the partition 27a through the attachment opening 33 of the inner box 29 and an opening of the partition 27a (partition opening 45 described later). Similarly, when manufacturing the refrigerator 200, after the partition 27b is attached to the inner box 29 of the box body 101, the urethane foam 23 is poured into the internal space 44 of the box body 101 from the injection opening on the back surface of the inner box 29 of the box body 101, and the urethane foam 23 is filled into the internal space 37ba of the partition main body 37b of the partition 27b through the attachment portion opening 33 of the inner box 29 and the opening of the partition 27b (partition opening 46 described later). Note that, with the partitions 27a, 27b attached to the attachment portions 34a, 34b of the inner box 29, the attachment portion opening 33 of the inner box 29 partially overlaps with the partition openings 45, 46 of the partitions 27a, 27b, and the urethane foam 23 flows into the insides of the partitions 27a, 27b through the overlapping region.

[0037] As shown in Fig. 11, among the multiple mounting openings 33, the mounting opening 33 provided on the front side of the inner box 29 (hereinafter also referred to as the mounting front opening 33c) and the mounting opening 33 provided on the rear side of the inner box 29 (hereinafter also referred to as the mounting rear opening 33a) are formed larger than the multiple mounting openings 33 provided between them (hereinafter also referred to as the mounting central opening 33b). The reason for this is as follows. When liquid urethane foam 23 is injected into the internal space 44 from the injection opening on the rear side of the inner box 29, the liquid urethane foam 23 flows into the front side of the inner box 29 in a highly fluid state. Therefore, the mounting front opening 33c provided on the front side of the inner box 29 is formed larger than the mounting central opening 33b so that the highly fluid urethane foam 23 injected from the rear side of the inner box 29 is sufficiently filled inside the partitions 27a, 27b. In addition, rear opening 33a for the mounting portion provided on the rear side of inner box 29 is formed larger than central opening 33b for the mounting portion so that urethane foam 23, whose fluidity has decreased by the time it reaches this opening, is filled at the rear inside partitions 27a, 27b.

[0038] Foods stored in the vegetable compartment 5 include radishes and burdock roots, which are taller than frozen foods, so it is desirable that the opening of the vegetable compartment 5 is longer in the vertical direction of the box body 101 than the opening of the freezer compartment 4. Therefore, in a refrigerator 100 of model A in which the vegetable compartment 5 is located below the freezer compartment 4, as shown in FIG. 14, the partition 27a, in which the upper flange 35a and the lower flange 36a in contact with the recess 30 have a longer vertical width than the upper flange 35a, is attached to a first position of the inner box 29. In a refrigerator 200 of model B in which the vegetable compartment 5 is located above the freezer compartment 4, as shown in FIG. 15, the partition 27b, in which the upper flange 35b has a longer vertical width than the lower flange 36b, is attached to a second position of the inner box 29. Here, the second position is lower than the first position. Moreover, the upper flange 35b of the partition 27b has a larger vertical width than the upper flange 35a of the partition 27a, and the lower flange 36b of the partition 27b has a smaller vertical width than the lower flange 36a of the partition 27a. The inner box 29 is common to the refrigerator 100 of model A and the refrigerator 200 of model B. The vertical width of the recess 30 is substantially the same as the maximum vertical width of the left side surface of the partition 27a formed by the upper flange 35a, the lower flange 36a, and the left side surface portion 38a. The vertical width of the recess 30 is substantially the same as the maximum vertical width of the left side surface of the partition 27b formed by the upper flange 35b, the lower flange 36b, and the left side surface portion 38b. In this way, when partition 27a, whose lower flange 36a has a vertical width longer than upper flange 35a, is attached to recess 30 whose vertical width is fixed, partition body 37a is located above partition body 37b, whose upper flange 35b has a vertical width longer than lower flange 36b. Therefore, the opening of vegetable compartment 5 can be made larger than the opening of freezer compartment 4.

[0039] FIG. 18 is a cross-sectional view of the left side surface 29a of the inner box 29 and the partition 27a in a state where the urethane foam 23 is not yet injected into the partition 27a according to the embodiment. FIG. 19 is a cross-sectional view of the left side surface 29a of the inner box 29 and the partition 27b in a state where the urethane foam 23 is not yet injected into the partition 27b according to the embodiment. Note that FIG. 18 is a cross-sectional view taken along the line XX in FIG. 17, and FIG. 19 is a cross-sectional view taken along the line XX in FIG. 17. FIG. 20 is a view of the left side surface portion 38a of the partition 27a of the refrigerator 100 according to the embodiment, as seen from the left side. FIG. 21 is a view of the left side surface portion 38b of the partition 27b of the refrigerator 200 according to the embodiment, as seen from the left side. Note that the dashed line in FIG. 20 indicates the left side surface portion 38a, and the dashed line in FIG. 21 indicates the left side surface portion 38b.

[0040] As shown in Figs. 18 and 20, a plurality of partition openings 45 (45a to 45c) are provided in the left side surface portion 38a of the partition 27a. The mounting portion opening 33 (see Fig. 11) formed in the left side surface 29a of the inner box 29 communicates with the plurality of partition openings 45. The lower region E1 of the mounting portion opening 33 formed in the left side surface 29a of the inner box 29 is blocked by the lower flange 36a and the left side surface portion 38a of the partition 27a. Therefore, when the urethane foam 23 is injected into the inside of the partition 27a through the mounting portion opening 33 of the inner box 29, it is possible to prevent the urethane foam 23 from leaking out of the partition 27a from the lower region E1 of the mounting portion opening 33. Similarly, as shown in Figs. 19 and 21, a plurality of partition openings 46 (46a to 46c) are provided in the left side surface portion 38b of the partition 27b. The mounting portion opening 33 formed on the left side surface 29a of the inner box 29 communicates with the multiple partition openings 46. An upper region E2 of the mounting portion opening 33 formed on the left side surface 29a of the inner box 29 is blocked by the upper flange 35b and the left side surface portion 38b of the partition 27b. Therefore, when the urethane foam 23 is injected into the partition 27b through the mounting portion opening 33 of the inner box 29, it is possible to prevent the urethane foam 23 from leaking out of the partition 27a from the upper region E2 of the mounting portion opening 33.

[0041] Fig. 22 is an enlarged view of the mounting portion 34b in a state where the partition 27a is attached to the right side surface 29b of the inner box 29 according to the embodiment. Fig. 23 is an enlarged view of the mounting portion 34b in a state where the partition 27b is attached to the right side surface 29b of the inner box 29 according to the embodiment. Fig. 22 is an enlarged view of the region F of the inner box 29 shown in Fig. 16, and Fig. 23 is an enlarged view of the same region as the region F of the inner box 29 shown in Fig. 16. In Fig. 22, the dashed line indicates the mounting portion 34b, and the dashed line indicates the right side surface portion 42a, and in Fig. 23, the dashed line indicates the mounting portion 34b, and the dashed line indicates the right side surface portion 42b.

[0042] As shown in FIG. 22, the right end of the partition body 37a of the partition 27a is provided with a plate-shaped upper flange 40a that is convex upward when the partition body 37a is attached to the attachment portion 34b of the inner box 29, and a plate-shaped lower flange 41a that is convex downward. Furthermore, the right end of the partition body 37a of the partition 27a is provided with a right side surface portion 42a that forms the right side surface of the partition body 37a. Also, as shown in FIG. 23, the right end of the partition body 37b of the partition 27b is provided with a plate-shaped upper flange 40b that is convex upward when the partition body 37b is attached to the attachment portion 34b of the inner box 29, and a plate-shaped lower flange 41b that is convex downward. Furthermore, the right end of the partition body 37b of the partition 27b is provided with a right side surface portion 42b that forms the right side surface of the partition body 37b.

[0043] In the partition 27a, in order to increase the front height of the lowest chamber (i.e., the vertical width of the front opening), the lower flange 41a is longer than the upper flange 40a as shown in FIG. 22. In the partition 27b, in order to increase the front height of the chamber one step above the lowest chamber (i.e., the vertical width of the front opening), the upper flange 40b is longer than the lower flange 41b as shown in FIG. 23. In addition, the upper flange 40b of the partition 27b has a longer vertical width than the upper flange 40a of the partition 27a, and the lower flange 41b of the partition 27b has a shorter vertical width than the lower flange 41a of the partition 27a. In the refrigerator 100 of model A and the refrigerator 200 of model B, the vertical width of the recess 30 is approximately the same as the maximum value of the vertical width of the right side surface of the partition 27a formed by the upper flange 40a, the lower flange 41a, and the right side surface portion 42a. Further, the vertical width of the recess 30 is substantially the same as the maximum vertical width of the right side surface of the partition 27b formed by the upper flange 40b, the lower flange 41b, and the right side surface portion 42b. Therefore, it is possible to provide two types of refrigerators 100 and 200 using a common inner box 29, in which the partitions 27a and 27b are attached at different positions.

[0044] 24 is a diagram showing the positional relationship between mounting portion opening 33 of inner box 29 and partition openings 45, 46 of partitions 27a, 27b in a state in which partitions 27a, 27b are attached to left side surface 29a of inner box 29 of refrigerators 100, 200 according to the embodiments. When partitions 27a, 27b are attached to mounting portions 34a, 34b of inner box 29, positions of partition main bodies 37a, 37b relative to inner box 29 are different between refrigerator 100 and refrigerator 200. Therefore, positions of partition openings 45, 46 for injecting urethane foam, formed on the side surfaces of partition main bodies 37a, 37b, relative to mounting portion opening 33 for injecting urethane foam of inner box 29 are also different.

[0045] When the partition 27a is attached to the left side surface 29a of the inner box 29, the partition central opening 45b of the partition 27a overlaps with the upper region of the mounting portion central opening 33b in a side view and is disposed above the mounting portion central opening 33b. On the other hand, when the partition 27b is attached to the left side surface 29a of the inner box 29, the partition central opening 46b of the partition 27b overlaps with the mounting portion central opening 33b in a side view and is disposed below the mounting portion central opening 33b. In other words, as shown in Fig. 24, the mounting portion central opening 33b is formed on the left side surface 29a of the inner box 29 in a shape that overlaps with both the partition central opening 45b of the partition 27a and the partition central opening 46b of the partition 27b. In other words, when the partitions 27a and 27b are attached to the left side surface 29a of the inner box 29, the opening area of ​​the central opening 33b for the mounting portion overlaps with the opening area of ​​the central openings 45b and 46b for the partitions in a side view. Although not shown, the opening area of ​​the rear opening 33a for the mounting portion overlaps with the opening area of ​​the central openings 45a and 46a for the partitions in a side view. Although not shown, the opening area of ​​the central opening 33b for the mounting portion overlaps with the opening area of ​​the central openings 45b and 46b for the partitions in a side view even when the partitions 27a and 27b are attached to the right side surface 29b of the inner box 29. Furthermore, the opening area of ​​the rear opening 33a for the mounting portion overlaps with the opening area of ​​the central openings 45a and 46a for the partitions in a side view.

[0046] Similarly, when the partition 27a is attached to the left side surface 29a of the inner box 29, the partition front opening 45c of the partition 27a overlaps with the attachment portion front opening 33c in a side view and is disposed above the attachment portion front opening 33c. On the other hand, when the partition 27b is attached to the left side surface 29a of the inner box 29, the partition front opening 46c of the partition 27b overlaps with the attachment portion front opening 33c in a side view and is disposed below the attachment portion front opening 33c. In other words, as shown in FIG. 24, the attachment portion front opening 33c is formed on the left side surface 29a of the inner box 29 in a shape that overlaps with both the partition front opening 45c of the partition 27a and the partition front opening 46c of the partition 27b. In other words, when the partitions 27a, 27b are attached to the left side surface 29a of the inner box 29, the opening area of ​​the attachment portion front opening 33c and the opening area of ​​the partition front openings 45c, 46c overlap in a side view. Although not shown, even when the partitions 27a, 27b are attached to the right side surface 29b of the inner box 29, the opening area of ​​the attachment portion front opening 33c and the opening area of ​​the partition front openings 45c, 46c overlap in a side view.

[0047] With this configuration, it is possible to fill both partitions 27a and 27b with urethane foam 23 in inner box 29 of the same shape, and a common mold for molding inner box 29 can be used for refrigerators 100 and 200. Therefore, it is not necessary to manufacture a plurality of molds, and manufacturing costs can be reduced. Partition central opening 45b and partition central opening 46b may overlap. Partition front opening 45c and partition front opening 46c may overlap.

[0048] When the partition 27b is attached to the inner box 29, the upper part of the partition body 37b becomes the vegetable compartment 5, and the lower part becomes the freezer compartment 4. In this case, the vegetable compartment 5 is sandwiched between the storage compartments with lower temperatures above and below, and is therefore likely to be cooled. Therefore, it is necessary to suppress the heat transfer between the upper and lower storage compartments and the vegetable compartment 5, and therefore a vacuum insulation material 50 is arranged inside the partition body 37b. Here, since the thermal conductivity of the vacuum insulation material 50 is about 10 times that of the urethane foam 23, by arranging the vacuum insulation material 50 inside the partition body 37b, the thickness in the vertical direction of the partition body 37b can be reduced more than that of the partition body 37a. On the other hand, when the partition 27a is attached to the inner box 29, the lower part of the partition body 37a becomes the vegetable compartment 5, and the upper part becomes the freezer compartment 4. In this case, the insulation performance of the partition body 37a may be lower than that of the vegetable compartment 5 above the freezer compartment 4, so the vacuum insulation material 50 is not arranged inside the partition body 37a, and the urethane foam 23 is filled inside the partition body 37a.

[0049] Fig. 25 is a vertical cross-sectional view of the portion of the partition 27b shown in Fig. 13 taken along the line AA. As shown in Fig. 25, the partition 27b includes a vacuum heat insulating material 50 inside the partition body 37b. The vacuum heat insulating material 50 is placed in the internal space 37ba of the partition body 37b, and is attached to the lower side surface 37bb of the partition body 37b from the inside via an adhesive member 47. By placing the vacuum heat insulating material 50 at the bottom inside the partition body 37b, a part of the front side of the upper side surface 37bc of the partition body 37b can be recessed, and a plurality of protrusions 37bd and recesses 37be (see Fig. 13) can be formed on the upper side surface 37bc. By providing a recess 37be on the upper side surface 37bc of the partition main body 37b, the storage space of the vegetable compartment 5 can be expanded, and by providing a protrusion 37bd, a surface of constant height can be formed in front of and behind the upper side surface 37bc, so that the jig that suppresses deformation of the partition main body 37b when injecting the urethane foam 23 can be used in common for the partitions 27a and 27b.

[0050] In the embodiment, in order to make the hole punching die for mounting portion opening 33 of inner box 29 common to model A and model B, the shape of mounting portion opening 33 of inner box 29 is sized to communicate with both partition openings 45, 46 of partitions 27a, 27a as shown in Fig. 24, but is not limited to this. Separate hole punching dies for mounting portion opening 33 may be used for model A and model B. In this case, the size of mounting portion opening 33 of inner box 29 can be reduced compared to the case where the hole punching die is common to model A and model B, and therefore the strength of the side surface of recess 30 of inner box 29 can be improved.

[0051] In the embodiment, the mounting opening 33 of the inner box 29 is sized to communicate with both the partitions 27a, 27a's partition openings 45, 46, but the shape of the mounting opening 33 of the inner box 29 is not limited thereto. The inner box 29 may be formed with two types of mounting openings 33: an opening that communicates only with the partition opening 45 of the partition 27a of the model A, and an opening that communicates only with the partition opening 46 of the partition 27b of the model B. If the position of the partition opening 45 when the partition 27a is attached to the inner box 29 is separated from the position of the partition opening 46 when the partition 27b is attached to the inner box 29, the opening area of ​​the mounting opening 33 can be reduced, thereby improving the strength of the side surface of the recess 30 of the inner box 29.

[0052] Fig. 26 is a diagram showing a positional relationship between the mounting opening of the inner box 29 and the partition openings 45, 46 of the partitions 27a, 27b in a state in which the partitions 27a, 27b are attached to the left side surface 29a of the inner box 29 of the first modified example of the refrigerators 100, 200 according to the embodiment. Fig. 27 is a diagram showing a positional relationship between the mounting opening of the inner box 29 and the partition openings 45, 46 of the partitions 27a, 27b in a state in which the partition 27a is attached to the left side surface 29a of the inner box 29 of the second modified example of the refrigerator 100 according to the embodiment. Fig. 28 is a diagram showing a positional relationship between the mounting opening of the inner box 29 and the partition openings 45, 46 of the partition 27b in a state in which the partition 27b is attached to the left side surface 29a of the inner box 29 of the second modified example of the refrigerator 200 according to the embodiment. FIG. 29 is a diagram showing the positional relationship between the mounting opening of inner box 29 and partition openings 45, 46 of partitions 27a, 27b when partitions 27a, 27b are attached to left side surface 29a of inner box 29 of a third modified example of refrigerators 100, 200 relating to the embodiments.

[0053] 24, the partition front opening 45c and the partition front opening 46c overlap with one mounting portion front opening 33c, and the partition central opening 45b and the partition central opening 46b overlap with one mounting portion central opening 33b, but the configuration of the mounting portion opening 33 formed on the left side surface 29a is not limited to this. As shown in FIG. 26, a first mounting portion front opening 47c and a second mounting portion front opening 48c spaced apart from each other may be formed on the left side surface 29a, so that when the partition 27a is attached to the left side surface 29a of the inner box 29, the partition front opening 45c overlaps with the first mounting portion front opening 47c in a side view, and when the partition 27b is attached to the left side surface 29a of the inner box 29, the partition front opening 46c overlaps with the second mounting portion front opening 48c in a side view. The first mounting portion central opening 47b, the second mounting portion central opening 48b, the first mounting portion rear opening (not shown), and the second mounting portion rear opening (not shown) have the same configuration.

[0054] Further, as shown in Figs. 27 and 28, either the first attachment portion front opening 47c or the second attachment portion front opening 48c is selectively formed on the left side surface 29a by one punching in accordance with the type of the partition. Then, as shown in Fig. 27, when the first attachment portion front opening 47c is formed, the partition 27a is attached to the left side surface 29a of the inner box 29, and as shown in Fig. 28, when the second attachment portion front opening 48c is formed, the partition 27b is attached to the left side surface 29a of the inner box 29. Similarly, either of the two openings is provided at the top and bottom in accordance with the type of the partition for the first attachment portion central opening 47b, the second attachment portion central opening 48b, the first attachment portion rear opening (not shown), and the second attachment portion rear opening (not shown). Even in such a case, it is possible to provide two types of refrigerators 100 and 200 having different mounting positions corresponding to the partitions 27a and 27b by using a common inner box 29.

[0055] 24, the front opening 33c for the mounting portion and the central opening 33b for the mounting portion have a vertically elongated shape, but the shape of the opening 33 for the mounting portion is not limited to this. As shown in Fig. 29, the front opening 33c for the mounting portion, the central opening 33b for the mounting portion, and the rear opening 33a for the mounting portion may have a shape that is not vertically elongated, such as a horizontally elongated shape or a square shape.

[0056] As described above, refrigerators 100, 200 according to the embodiments include an outer box 22 constituting an outer shell, an inner box 29 arranged to form a first space between the outer box 22 and the inner box 29 having an injection opening for injecting an insulating material, and insulating material filled in the first space. Box body 101 has a storage space for storing food therein, and partition bodies 37a, 37b having a second space therein and dividing the storage space into a number of storage compartments with different temperature zones, and partitions 27a, 27b having locking portions for fixing partition bodies 37a, 37b to inner box 29 and partition openings 45, 46 formed on the side surfaces of partition bodies 37a, 37b. Furthermore, the inner box 29 has mounting portions 34a, 34b to which the locking portions are attached, and when the locking portions are attached to the mounting portions 34a, 34b and the partition bodies 37a, 37b are fixed to the inner box 29, the mounting portions 34a, 34b have an opening 33 for the mounting portion on the surface facing the side surface, and the opening 33 for the mounting portion communicates with the first space. When the inner box 29 is viewed from the side, the partition bodies 37a, 37b can be attached to the inner box 29 at a position above the opening 33 for the mounting portion where the opening 33 for the mounting portion and the partition openings 45, 46 overlap, or at a position below the opening 33 for the mounting portion where the opening 33 for the mounting portion and the partition openings 45, 46 overlap.

[0057] According to the refrigerators 100 and 200 according to the embodiments, the partition bodies 37a and 37b can be attached to the inner box 29 at a position where the mounting opening 33 and the partition openings 45 and 46 overlap above the mounting opening 33, or at a position where the mounting opening 33 and the partition openings 45 and 46 overlap below the mounting opening 33, when the inner box 29 is viewed from the side. Therefore, the vertical positions of the partition bodies 37a and 37b change depending on whether the partition bodies 37a and 37b are attached at a position where the mounting opening 33 and the partition openings 45 and 46 overlap above the mounting opening 33 or a position where the partition bodies 37a and 37b are attached at a position where the mounting opening 33 and the partition openings 45 and 46 overlap below the mounting opening 33. In either case, since the mounting opening 33 and the partition openings 45, 46 overlap, the heat insulating material injected from the injection opening into the first space can be injected into the second space of the partition bodies 37a, 37b through the mounting opening 33 and the partition openings 45, 46 that communicate with the first space. In this way, since the mounting positions of the partitions 27a, 27b mounted in the box body 101 can be changed, an appropriate opening can be secured for each storage chamber, and usability for the user can be improved. Furthermore, since the mounting positions of the partitions 27a, 27b mounted in the box body 101 can be changed, and the heat insulating material injected from the injection opening into the first space can be injected into the second space of the partition bodies 37a, 37b regardless of the mounting positions of the partitions 27a, 27b mounted in the box body 101, the mold for molding the inner box 29 can be shared, and there is no need to manufacture multiple molds, so manufacturing costs can be reduced. In other words, usability for the user can be improved while reducing manufacturing costs. Furthermore, since the structure requires that the box 101 be manufactured individually for each model, compared to a conventional structure in which a common box 101 is manufactured regardless of the model and the temperature of each storage compartment is freely set by the user, it is possible to configure an optimal cooling structure and insulation structure for the position of each storage compartment, thereby reducing power consumption and internal volume loss.

[0058] In addition, in the refrigerators 100 and 200 according to the embodiments, the multiple mounting portion openings 33 include a rear mounting portion opening 33a formed on the rear side of the inner box 29, a front mounting portion opening 33c formed forward of the inner box 29 from the rear mounting portion opening 33a, and multiple mounting portion central openings 33b formed between the rear mounting portion opening 33a and the front mounting portion opening 33c, and the rear mounting portion opening 33a and the front mounting portion opening 33c have a larger area than each of the mounting portion central openings 33b.

[0059] According to the refrigerators 100 and 200 of the embodiments, when liquid insulating material is injected into the internal space 44 from the injection opening on the back surface of the inner box 29, the liquid insulating material flows in a highly fluid state into the front side of the inner box 29, so by forming the mounting portion front opening 33c larger than the mounting portion central opening 33b, the highly fluid insulating material injected from the back surface side of the inner box 29 can be sufficiently filled inside the partitions 27a and 27b. Also, by forming the mounting portion rear opening 33a larger than the mounting portion central opening 33b, the insulating material whose fluidity has decreased by the time it reaches the mounting portion rear opening 33a can be filled in the rear of the interiors of the partitions 27a and 27b.

[0060] In addition, in refrigerator 100 according to the embodiment, partition 27a is a first partition attached to inner box 29 so that mounting opening 33 and partition opening 45 overlap above mounting opening 33, and when the first partition is attached to inner box 29, a part of mounting opening 33 is blocked by lower flanges 36a, 41a of the locking portion of the first partition and a side surface of partition body 37a.
