Description

refrigerator

This disclosure relates to a partition structure of a refrigerator.

In the past, refrigerators had multiple storage rooms inside the cabinet. For example, the multiple storage rooms included: a refrigerator controlled to a refrigeration temperature zone; a freezer controlled to a freezing temperature zone; and a vegetable room controlled to a vegetable room temperature zone. In this way, the space inside each storage room is set to a different temperature zone in accordance with the food stored, and in response to the needs of the user, even refrigerators with the same capacity range may have different positions of the vegetable room and freezer room inside the cabinet.

In addition, in a refrigerator having multiple storage chambers inside the cabinet, each storage chamber stores different foods, so each storage chamber has an appropriate compartment opening height and set temperature. Therefore, when manufacturing a refrigerator in which the configuration of each storage chamber in the cabinet is different from that in the past, in order to install a plate-shaped partition in the cabinet to match the configuration of each storage chamber, the structure of the partition installed in the inner box must be changed, and the cabinet is generally formed individually.

In this way, the cabinets are formed individually, and the storage chambers controlled to different temperature zones are arranged at different positions to provide multiple styles of refrigerators, which can expand the options for consumers. However, on the other hand, even for refrigerators with the same capacity, the appropriate compartment opening heights of the storage chambers are different, so the installation position of the partition installed in the cabinet must be changed. And because the inner boxes with changed installation positions each require different molds, it is necessary to manufacture multiple molds, which leads to high costs.

Therefore, in order to reduce the manufacturing cost of the refrigerator caused by the change of the storage room configuration and improve the convenience of the user, there is a refrigerator in which the user can freely set the storage room of the refrigerator with multiple drawer doors as a refrigerator or a freezer (for example, refer to Patent Document 1).

In Patent Document 1, the user can freely set the storage compartments of the multiple drawer doors of the refrigerator as refrigerator compartments or freezer compartments, thereby providing refrigerators with the same capacity and different configurations of storage compartments located inside the cabinet.

[Prior Art Literature] [Patent Literature]

Patent document 1: Japanese Patent No. 6655747

However, in the refrigerator of Patent Document 1, since the temperature of each storage chamber is switched while the height of the compartment opening of each storage chamber is fixed, it is impossible to ensure an appropriate compartment opening in the storage chamber according to the size of each stored food, which may affect the user's convenience.

This disclosure is made to solve the above-mentioned problems, and its purpose is to provide a refrigerator that reduces manufacturing costs and improves user convenience.

The refrigerator disclosed in the present invention comprises: a box body, which has an outer box, an inner box and a heat insulating material and has a storage space for storing food inside, the outer box constitutes an outer contour, the inner box is configured to form a first space between the outer box and has an injection opening for injecting the heat insulating material, and the heat insulating material is filled in the first space; and a partition, which has a partition body and a locking portion, the partition body has a second space formed inside and a partition opening formed on the side, and divides the storage space into a plurality of storage rooms with different temperature zones, the locking portion fixes the partition body to the inner box, and the inner box has The mounting portion for mounting the aforementioned stopper portion, the aforementioned mounting portion having a surface formed with an opening for the mounting portion, the surface being opposite to the aforementioned side surface of the aforementioned partition body when the aforementioned stopper portion is mounted on the aforementioned mounting portion and the aforementioned partition body is fixed to the aforementioned inner box, the aforementioned mounting portion opening is connected to the aforementioned first space, and when the aforementioned inner box is viewed from the side, the aforementioned partition body can be mounted on the aforementioned inner box at a position above the aforementioned mounting portion opening and the aforementioned mounting portion opening overlaps with the aforementioned partition opening, or can be mounted at a position below the aforementioned mounting portion opening and the aforementioned mounting portion opening overlaps with the aforementioned partition opening.

According to the refrigerator disclosed in the present invention, when the mounting opening is viewed from the side of the inner box, the partition body can be mounted above the mounting opening of the inner box and at a position where the mounting opening and the partition opening overlap, or the partition body can be mounted below the mounting opening of the inner box and at a position where the mounting opening and the partition opening overlap. Therefore, when the partition body is mounted above the mounting opening and at a position where the mounting opening and the partition opening overlap, the position of the partition body in the up-down direction will change compared to when the partition body is mounted below the mounting opening and at a position where the mounting opening and the partition opening overlap. Furthermore, in any case, since the opening for the mounting portion and the opening for the partition overlap, the heat insulating material injected from the injection opening into the first space can be injected into the second space of the partition body through the opening for the mounting portion and the opening for the partition that are connected to the first space. In this way, the mounting position of the partition body installed in the box can be changed, so that the appropriate compartment opening can be ensured in each storage room, thereby improving the user's convenience. Furthermore, since the mounting position of the partition body installed in the box can be changed, and regardless of the mounting position of the partition body installed in the box, the heat insulating material injected from the injection opening into the first space can be injected into the second space of the partition body, so the manufacturing cost can be suppressed. That is, the manufacturing cost can be suppressed while improving the user's convenience.

In addition, a machine room 21 is provided at the lower back side of the refrigerator 100, a cooling room 39 is provided above the machine room 21, and a duct 26 is provided above the cooling room 39. The machine room 21 is provided with a compressor 8, etc., and the cooling room 39 is provided with a cooler 17 and a cooling fan 25 provided above it, etc.

As shown in Fig. 2, Fig. 3 and Fig. 5, the refrigerator 200 of the embodiment is model B, and has a housing 101 like the refrigerator 100. The housing 101 is composed of an outer box 22 constituting an outer frame, an inner box 29 forming an inner space 44 between the outer box 22 and the inner box 29, and a foamed urethane 23 which is a heat insulating material filling the inner space 44. In addition, hereinafter, the inner space 44 is also referred to as the first space. Inside the housing 101, a storage space for storing food is provided, and the storage space is divided by a partition 27b described later, and a plurality of storage rooms with different temperature zones are provided. Specifically, as a plurality of storage rooms, there are provided a refrigerator room 1, an ice making room 2, a small freezer room 3, a freezer room 4 belonging to the second storage room, and a vegetable room 5 belonging to the first storage room.

FIG. 6 is a diagram showing the refrigerant circuit 103 of the refrigerators 100 and 200 of the embodiment. FIG. 7 is a connection diagram of the refrigerant piping inside the refrigerator 100 of the embodiment. FIG. 8 is a connection diagram of the refrigerant piping inside the refrigerator 100 of the embodiment of the modification. In addition, the structure of the refrigerant circuit 103 is the same in the refrigerator 100 and the refrigerator 200, so the refrigerator 100 is used as an example for explanation. In addition, the arrow shown in FIG. 6 indicates the flow of the refrigerant. In addition, in FIG. 7 and FIG. 8, the oblique lower right direction shown by the hollow arrow is the front side of the refrigerator 100.

The refrigerator 100 of the embodiment has a refrigerant circuit 103 for refrigerant circulation. As shown in FIG6 , the refrigerant circuit 103 has a compressor 8, a fin-tube type machine room condenser 9, a left side condensation pipe 10, a top condensation pipe 11, a back condensation pipe 12, a right side condensation pipe 13, an anti-dew pipe 14, a dryer 15, a capillary tube 16 as a pressure reducing device, a cooler 17, a muffler (liquid storage device) 18, and an intake pipe 19. Here, the machine room condenser 9, the left side condensation pipe 10, the top condensation pipe 11, the back condensation pipe 12, the right side condensation pipe 13, and the anti-dew pipe 14 are condensation system pipes.

As shown in FIG7 , the compressor 8, the machine room condenser 9 and the dryer 15 are arranged in the machine room 21 arranged at the lower part of the back side of the refrigerator 100. In addition, a part of the left side condensation pipe 10 arranged inside the left side panel constituting the left side of the cabinet 101 extends toward the top side and is connected to the top condensation pipe 11 arranged inside the top panel constituting the top. Furthermore, a part of the right side condensation pipe 13 arranged inside the right side panel constituting the right side of the cabinet 101 may be extended toward the top side and connected to the top condensation pipe 11, instead of the left side condensation pipe 10 being connected to the top condensation pipe 11. In addition, the left side condensation pipe 10, the top condensation pipe 11, the back 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 (not shown) with aluminum tape.

Furthermore, the refrigerator 100 is installed in the machine room 21 and includes a machine room cooling fan (not shown) for cooling the machine room condenser 9 and the compressor 8.

Furthermore, if it is the downstream side of the anti-dew pipe 14 passing through the condensation system piping, two capillary tubes 16 or multiple coolers 17 can be installed. Furthermore, when two capillary tubes 16 are installed, a three-way valve is installed on the upstream side of the capillary tube 16. In addition, as long as the machine room condenser 9, the top condensation pipe 11 and the back condensation pipe 12 only use the left side condensation pipe 10 and the right side condensation pipe 13 to exert their condensation capacity, there is no problem even if they are not installed.

As shown in FIG7 , the anti-condensation piping 14 is arranged on the front surface flange 24 in a manner of surrounding the refrigerating chamber 1, the ice making chamber 2, the small freezing chamber 3, the freezing chamber 4 and the vegetable chamber 5, i.e., each storage chamber. In addition, the anti-condensation piping 14 is connected to the right side condensation piping 13 at the lower right inner side, and is connected to the dryer 15 arranged in the machine chamber 21 at the lower left inner side.

In addition, when the insulation performance between the wall of the refrigerating chamber 1 and the outer box 22 is good, as shown in FIG8 , the anti-condensation piping 14 can also be arranged on the front surface flange 24 in a manner to surround each storage chamber other than the refrigerating chamber 1. That is, the anti-condensation piping 14 may not be arranged on the upper side and the left and right front surface flanges 24 of the refrigerating chamber 1. Here, the so-called good insulation performance between the wall of the refrigerating chamber 1 and the outer box 22 refers to, for example, a large distance between the wall of the refrigerating chamber 1 and the outer box 22, i.e., a large insulation thickness, or a vacuum insulation material is arranged between the wall of the refrigerating chamber 1 and the outer box 22.

As shown in FIG. 4 , the cold air generated by cooling the air in the cooling chamber 39 by the refrigerant circuit 103 is sent by the cooling fan 25 installed above the cooler 17. The sent cold air is supplied to the freezing chamber 4, the ice making chamber 2, the small freezing chamber 3 and the refrigerating chamber 1 through the duct 26 on the back of the refrigerator 100. The return cold air from the refrigerating chamber 1 is supplied to the vegetable chamber 5 through the return air duct for the refrigerating chamber (not shown). The cold air supplied to the vegetable chamber 5 is returned to the cooler 17 through the return duct (not shown). The temperature of each storage chamber is detected by a thermistor installed in each storage chamber, and is controlled by adjusting the opening of the damper (not shown) installed in each storage chamber, the output of the compressor 8, and the air supply volume of the cooling fan 25, so that it becomes a preset temperature.

In the refrigerator 200, the cooled cold air generated by cooling the air in the cooling chamber 39 by the refrigerant circuit 103 is sent by the cooling fan 25 provided above the cooler 17 as shown in FIG5. And the sent cold air is supplied to the freezing chamber 4, the ice making chamber 2, the small freezing chamber 3 and the refrigerating chamber 1 through the duct 26 on the back of the refrigerator 200. The return cold air from the refrigerating chamber 1 is supplied to the vegetable chamber 5 through the return air duct for the refrigerating chamber (not shown). The cold air supplied to the vegetable chamber 5 returns to the cooler 17 through the return duct (not shown). In the refrigerator 200, since the cooler 17 is disposed 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 the vegetable compartment 5 from the cooler 17. Furthermore, the heat insulating material 28 may also include a vacuum heat insulating material. The temperature of each storage chamber is detected by a thermistor disposed in each storage chamber, and is controlled by adjusting the opening of a damper (not shown) disposed in each storage chamber, the output of the compressor 8, and the air supply volume of the cooling fan 25, so as to achieve a preset temperature.

Refrigerator 100 and refrigerator 200 have inner box 29 indicated by thick lines in FIG. 4 and FIG. 5, and inner box 29 is formed in a common shape in refrigerator 100 and refrigerator 200. In refrigerator 100 and refrigerator 200, the types of storage chambers of refrigerator compartment 1, ice making chamber 2, small freezer compartment 3, freezer compartment 4 and vegetable compartment 5 are the same, and the vegetable compartment 5 of refrigerator 100 is arranged at the bottom section, and the freezer compartment 4 of refrigerator 200 is arranged at the bottom section. The upper and lower widths of the front openings of vegetable compartment 5 and freezer compartment 4 are different. Therefore, between vegetable compartment 5 and freezer compartment 4, partitions 27a and 27b are provided to partition vegetable compartment 5 and freezer compartment 4, and the upper and lower positions of the partitions 27a and 27b are provided in refrigerator 100 and refrigerator 200.

FIG. 9 is a perspective view of the lower part of the inner box 29 on which the partitions 27a and 27b of the refrigerator 100 and 200 of the embodiment are installed. FIG. 10 is an enlarged view of the area C of the inner box 29 shown in FIG. 9. FIG. 11 is a side view of the periphery of the recessed portion of the inner box 29 of the refrigerator 100 and 200 of the embodiment. As shown in FIG. 10, a recessed portion 30 is formed on the left side surface 29a of the inner box 29 at the position where the partitions 27a and 27b are installed, which is recessed toward the outside of the inner box 29 (the left side surface 29a is the left side when the inner box 29 is viewed from the front). The recessed portion 30 extends rearward from the opening of the inner box 29 in a substantially horizontal direction, and is formed to have a certain width in the upper and lower parts, and the upper and lower boundaries of the recessed portion 30 are formed by a convex portion protruding toward the inner side of the refrigerator. Furthermore, the convex portion above the concave portion 30 is called an upper convex portion 31, and the convex portion below the concave portion 30 is called a lower convex portion 32. As shown in FIG. 11, a plurality of openings 33 (33a to 33c) for mounting portions are formed in the concave portion 30 for injecting the foamed urethane 23 into the interior of the partitions 27a and 27b. The plurality of openings 33 for mounting portions are connected to the internal space 44 (see FIG. 4 and FIG. 5). In addition, by forming the concave portion 30, the upper convex portion 31 and the lower convex portion 32 on the left side surface 29a of the inner box 29, a mounting portion 34a for mounting the partitions 27a and 27b is formed in the inner box 29. Moreover, between the upper convex portion 31 and the lower convex portion 32, the upper side flanges 35a, 40a and the lower side flanges 36a, 41a of the partitions 27a, 27b described later are pressed into the rear of the inner box 29 in a manner that they slide on the side surface of the recess 30. Thus, the upper side flanges 35a, 40a and the lower side flanges 36a, 41a of the partitions 27a, 27b are clamped between the upper convex portion 31 and the lower convex portion 32, and the partitions 27a, 27b are mounted on the inner box 29. Furthermore, although not shown, a mounting portion 34b having the same structure as the mounting portion 34a is formed on the right side surface 29b of the inner box 29 at approximately the same height as the mounting portion 34a.

FIG. 12 is an overall three-dimensional view of the partition 27a installed on the mounting parts 34a and 34b of the inner box 29 of the refrigerator 100 of the embodiment. FIG. 13 is an overall three-dimensional view of the partition 27b installed on the mounting parts 34a and 34b of the inner box 29 of the refrigerator 200 of the embodiment. FIG. 14 is an enlarged three-dimensional view of the left front part D1 of the partition 27a shown in FIG. 12. FIG. 15 is an enlarged three-dimensional view of the left front part D2 of the partition 27b shown in FIG. 13.

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 partition body 37a, a left side surface 38a, a right side surface 42a, upper flanges 35a, 40a and lower flanges 36a, 41a. The partition body 37a is plate-shaped and has an internal space 37aa (hereinafter also referred to as the second space). The left side surface 38a forms the left side surface of the partition body 37a, and the right side surface 42a forms the right side surface of the partition body 37a. 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 separator 27b is composed of a separator body 37b, a left side surface 38b, a right side surface 42b, upper side flanges 35b, 40b and lower side flanges 36b, 41b. The separator body 37b is plate-shaped and has an internal space 37ba (hereinafter also referred to as a second space). The left side surface 38b forms the left side surface of the separator body 37b, and the right side surface 42b forms the right side surface of the separator body 37b. The separator 27a has upper side flanges 35a, 40a extending upward from the left and right side surfaces and lower side flanges 36a, 41a extending downward from the left and right side surfaces as a stopper. Similarly, the partition 27b has upper flanges 35b and 40b extending upward from the left and right side surfaces and lower flanges 36b and 41b extending downward from the left and right side surfaces as locking portions. The partition 27a is fixed to the inner box 29 from the back side of the inner box 29 by screws not shown in the figure. In addition, the partition 27b is fixed to the inner box 29 from the back side of the inner box 29 by screws not shown in the figure. By fixing the partitions 27a and 27b in this way, the foamed urethane 23 can be prevented from flowing out from between the partition 27a and the inner box 29 or from between the partition 27b and the inner box 29.

FIG. 16 is a longitudinal section view of the vegetable compartment 5 in the state where the partition 27a is installed on the inner box 29 of the refrigerator 100 of the embodiment. FIG. 17 is a schematic diagram of the area F of the inner box 29 and the partition 27a shown in FIG. 16. Furthermore, FIG. 16 schematically shows a longitudinal section along the left-right direction, and a dot chain shows the installation parts 34a and 34b. Moreover, in FIG. 16, the vegetable compartment 5 is provided at the bottom of the refrigerator 100. Furthermore, FIG. 17 shows the flow path of the foamed urethane 23 injected into the internal space 44 of the box body 101 from the injection opening (not shown) provided on the back of the inner box 29 of the box body 101, and the arrow shows the flow of the foamed urethane 23.

The internal space of the partition body 37a, 37b of the partitions 27a, 27b is filled with foamed urethane 23 as a heat insulating material. As shown in Figures 16 and 17, when the refrigerator 100 is manufactured, after the partition 27a is installed in the inner box 29 of the box body 101, the foamed urethane 23 is injected into the internal space 44 of the box body 101 from the injection opening on the back of the inner box 29 of the box body 101 (refer to Figures 4 and 5), and the foamed urethane 23 is filled into the internal space 37aa of the partition body 37a of the partition 27a through the installation opening 33 of the inner box 29 and the opening of the partition 27a (the partition opening 45 described later). Similarly, when manufacturing the refrigerator 200, after the partition 27b is installed in the inner box 29 of the box body 101, the foamed urethane 23 is allowed to flow into the internal space 44 of the box body 101 from the injection opening on the back side of the inner box 29 of the box body 101, and the foamed urethane 23 is filled into the internal space 37ba of the partition body 37b of the partition 27b through the opening 33 for the installation part of the inner box 29 and the opening of the partition 27b (the partition opening 46 described later). In addition, when the partitions 27a and 27b are installed in the mounting parts 34a and 34b of the inner box 29, the mounting opening 33 of the inner box 29 partially overlaps with the partition openings 45 and 46 of the partitions 27a and 27b, and the foamed urethane 23 flows into the interior of the partitions 27a and 27b through the overlapping area.

As shown in FIG. 11 , the opening 33 for the mounting portion provided on the front side of the inner box 29 (hereinafter, also referred to as the front opening 33c for the mounting portion) and the opening 33 for the mounting portion provided on the rear side of the inner box 29 (hereinafter, also referred to as the rear opening 33a for the mounting portion) are formed larger than the plurality of openings for the mounting portion 33 provided therebetween (hereinafter, also referred to as the central opening 33b for the mounting portion). The reason is as follows. When the liquid foaming urethane 23 is injected into the internal space 44 from the injection opening on the back side of the inner box 29, the liquid foaming urethane 23 flows into the front side of the inner box 29 in a highly fluid state. Therefore, the front opening 33c for the mounting part provided on the front side of the inner box 29 is formed larger than the central opening 33b for the mounting part in order to allow the foamed urethane 23 in a highly fluid state injected from the back side of the inner box 29 to be fully filled in the interior of the partitions 27a and 27b. Furthermore, the rear opening 33a for the mounting part provided on the rear side of the inner box 29 is formed larger than the central opening 33b for the mounting part because the foamed urethane 23 with reduced fluidity is filled in the rear of the interior of the partitions 27a and 27b until the opening thereof.

Since the food stored in the vegetable compartment 5 includes foods that are taller than frozen foods, such as radish and burdock, it is preferable that the length of the compartment opening of the vegetable compartment 5 along the vertical direction of the box body 101 is greater than the length of the compartment opening of the freezing chamber 4 along the vertical direction of the box body 101. Therefore, in the refrigerator 100 of model A in which the vegetable compartment 5 is arranged below the freezing chamber 4, as shown in FIG. 14, of the upper flange 35a and the lower flange 36a in contact with the recess 30, the partition 27a in which the vertical width of the lower flange 36a is longer than that of the upper flange 35a is installed at the first position of the inner box 29. In the refrigerator 200 of model B in which the vegetable compartment 5 is arranged above the freezing compartment 4, as shown in FIG. 15, of the upper flange 35a and the lower flange 36a in contact with the recess 30, the partition 27b whose upper and lower widths of the upper flange 35b are longer than those of the lower flange 36b is installed at the second position of the inner box 29. Here, the second position is a position lower than the first position. In addition, the upper flange 35b of the partition 27b has a longer upper and lower width than the upper flange 35a of the partition 27a, and the lower flange 36b of the partition 27b has a shorter upper and lower width than the lower flange 36a of the partition 27a. Moreover, the inner box 29 is common in the refrigerator 100 of model A and the refrigerator 200 of model B. In addition, the upper and lower widths of the recessed portion 30 are substantially the same as the maximum value of the upper and lower widths of the left side surface of the partition 27a formed by the upper convex edge 35a, the lower convex edge 36a and the left side surface 38a. In addition, the upper and lower widths of the recessed portion 30 are substantially the same as the maximum value of the upper and lower widths of the left side surface of the partition 27b formed by the upper convex edge 35b, the lower convex edge 36b and the left side surface 38b. In this way, when the partition 27a whose upper and lower widths of the lower flange 36a are installed in the recess 30 with fixed upper and lower widths, the position of the partition body 37a is located higher than when the partition 27b whose upper and lower widths of the upper flange 35b are installed is located higher. Therefore, the compartment opening of the vegetable compartment 5 can be made larger than the compartment opening of the freezer compartment 4.

Fig. 18 is a diagram showing the left side surface 29a of the inner box 29 and the cross section of the partition 27a in a state where the foamed urethane 23 is not injected into the interior of the partition 27a of the embodiment. Fig. 19 is a diagram showing the left side surface 29a of the inner box 29 and the cross section of the partition 27b in a state where the foamed urethane 23 is not injected into the interior of the partition 27b of the embodiment. Fig. 18 is an arrow view of the X-X cross section of Fig. 17, and Fig. 19 is an arrow view of the cross section at the same position as the X-X cross section of Fig. 17. Fig. 20 is a diagram of the left side surface 38a of the partition 27a of the refrigerator 100 of the embodiment as viewed from the left side. Fig. 21 is a diagram of the left side surface 38b of the partition 27b of the refrigerator 200 of the embodiment as viewed from the left side. Furthermore, the dotted line in FIG. 20 represents the left side of the face 38a, and the dotted line in FIG. 21 represents the left side of the face 38b.

As shown in FIG. 18 and FIG. 20 , a plurality of partition openings 45 (45a to 45c) are provided on the left side surface 38a of the partition 27a. Moreover, the mounting opening 33 (see FIG. 11 ) formed on the left side surface 29a of the inner box 29 is connected to the plurality of partition openings 45. Furthermore, the area E1 below the mounting opening 33 formed on the left side surface 29a of the inner box 29 is blocked by the lower side flange 36a of the partition 27a and the left side surface 38a. Therefore, when the foamed urethane 23 is injected into the interior of the partition 27a through the mounting opening 33 of the inner box 29, the foamed urethane 23 can be prevented from leaking from the area E1 below the mounting opening 33 to the outside of the partition 27a. Similarly, as shown in FIG. 19 and FIG. 21, a plurality of partition openings 46 (46a~46c) are provided on the left side surface 38b of the partition 27b. Moreover, the mounting opening 33 formed on the left side surface 29a of the inner box 29 is connected to the plurality of partition openings 46. In addition, the area E2 on the upper side of the mounting opening 33 formed on the left side surface 29a of the inner box 29 is blocked by the upper side flange 35b and the left side surface 38b of the partition 27b. Therefore, when the foamed urethane 23 is injected into the interior of the partition 27b through the mounting opening 33 of the inner box 29, the foamed urethane 23 can be prevented from leaking from the area E2 on the upper side of the mounting opening 33 to the outside of the partition 27a.

FIG. 22 is an enlarged view of the mounting portion 34b in the state where the partition 27a is mounted on the right side 29b of the inner box 29 of the embodiment. FIG. 23 is an enlarged view of the mounting portion 34b in the state where the partition 27b is mounted on the right side 29b of the inner box 29 of the embodiment. Furthermore, FIG. 22 is an enlarged view of the area F of the inner box 29 shown in FIG. 16, and FIG. 23 is an enlarged view of the same area as the area F of the inner box 29 shown in FIG. 16. In addition, a dotted line in FIG. 22 represents the mounting portion 34b, and a dashed line represents the right side surface 42a, and a dotted line in FIG. 23 represents the mounting portion 34b, and a dashed line represents the right side surface 42b.

As shown in FIG22, at the right end of the partition body 37a of the partition 27a, there are provided a plate-shaped upper side flange 40a that protrudes upward when the partition body 37a is mounted on the mounting portion 34b of the inner box 29, and a plate-shaped lower side flange 41a that protrudes downward. In addition, at the right end of the partition body 37a of the partition 27a, there is provided a right side surface portion 42a that forms the right side surface of the partition body 37a. Furthermore, as shown in FIG23, at the right end of the partition body 37b of the partition 27b, there are provided a plate-shaped upper side flange 40b that protrudes upward when the partition body 37b is mounted on the mounting portion 34b of the inner box 29, and a plate-shaped lower side flange 41b that protrudes downward. Furthermore, at the right end of the separator body 37b of the separator 27b, there is a right side surface 42b forming the right side surface of the separator body 37b.

In the partition 27a, in order to increase the compartment opening height of the lowest chamber (i.e., the upper and lower widths of the front surface opening), as shown in FIG22, the lower flange 41a is longer than the upper flange 40a. In addition, in the partition 27b, in order to increase the compartment opening height of the upper chamber than the lowest chamber (i.e., the upper and lower widths of the front surface opening), as shown in FIG23, the upper flange 40b is longer than the lower flange 41b. In addition, the upper and lower widths of the upper flange 40b of the partition 27b are longer than the upper flange 40a of the partition 27a, and the upper and lower widths of the lower flange 41b of the partition 27b are shorter than the lower flange 41a of the partition 27a. Moreover, in the refrigerator 100 of model A and the refrigerator 200 of model B, the upper and lower widths of the recess 30 are approximately the same as the maximum value of the upper and lower widths of the right side surface of the partition 27a formed by the upper flange 40a, the lower flange 41a and the right side surface 42a. In addition, the upper and lower widths of the recess 30 are approximately the same as the maximum value of the upper and lower widths of the right side surface of the partition 27b formed by the upper flange 40b, the lower flange 41b and the right side surface 42b. Therefore, the common inner box 29 can be used to provide two types of refrigerators 100 and 200 with different installation positions of the partitions 27a and 27b.

FIG. 24 is a diagram showing the positional relationship between the opening 33 for the mounting portion of the inner box 29 and the openings 45 and 46 for the partitions of the partitions 27a and 27b when the partitions 27a and 27b are mounted on the left side 29a of the inner box 29 of the refrigerators 100 and 200 of the embodiment. In the refrigerators 100 and 200, when the partitions 27a and 27b are mounted on the mounting portions 34a and 34b of the inner box 29, the positions of the partition bodies 37a and 37b relative to the inner box 29 are different. Therefore, the positions of the partition openings 45 and 46 for injecting foamed urethane formed on the side surfaces of the partition bodies 37a and 37b relative to the mounting portion opening 33 for injecting foamed urethane of the inner box 29 are also different.

When the partition 27a is mounted on the left side surface 29a of the inner box 29, the partition central opening 45b of the partition 27a overlaps with the area on the upper side of the central opening 33b for the mounting portion in a side view, and is arranged on the upper side of the central opening 33b for the mounting portion. On the other hand, when the partition 27b is mounted on the left side surface 29a of the inner box 29, the partition central opening 46b of the partition 27b overlaps with the central opening 33b for the mounting portion in a side view, and is arranged on the lower side of the central opening 33b for the mounting portion. That is, as shown in FIG. 24, the central opening 33b for the mounting portion is formed on the left side surface 29a of the inner box 29 in the shape of the partition central opening 45b for the partition 27a and the partition central opening 46b for the partition 27b overlapping each other. In other words, when the partitions 27a and 27b are mounted on 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 when viewed from the side. In addition, although not shown, the opening area of the rear opening 33a for the mounting portion overlaps with the opening area of the openings 45a and 46a for the partitions when viewed from the side. In addition, although not shown, even when the partitions 27a and 27b are mounted on the right side surface 29b 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 when viewed from the side. In addition, the opening area of the rear opening 33a for the mounting portion and the opening areas of the openings 45a and 46a for the partition overlap when viewed from the side.

Similarly, the front opening 45c for the partition 27a of the partition 27a overlaps with the front opening 33c for the mounting portion in a side view when the partition 27a is mounted on the left side 29a of the inner box 29, and is arranged on the upper side of the front opening 33c for the mounting portion. On the other hand, the front opening 46c for the partition 27b overlaps with the front opening 33c for the mounting portion in a side view when the partition 27b is mounted on the left side 29a of the inner box 29, and is arranged on the lower side of the front opening 33c for the mounting portion. That is, as shown in FIG. 24, the front opening 33c for the mounting portion is formed on the left side 29a of the inner box 29 in a shape overlapping with the front opening 45c for the partition 27a and the front opening 46c for the partition 27b. In other words, when the partitions 27a and 27b are mounted on the left side 29a of the inner box 29, the opening area of the front opening 33c for the mounting portion overlaps with the opening area of the front openings 45c and 46c for the partition when viewed from the side. Furthermore, although not shown, even when the partitions 27a and 27b are mounted on the right side 29b of the inner box 29, the opening area of the front opening 33c for the mounting portion overlaps with the opening area of the front openings 45c and 46c for the partition when viewed from the side.

By setting such a structure, the foamed urethane 23 can be filled into both the partition 27a and the partition 27b using the inner box 29 of the same shape, so that the mold for forming the inner box 29 of the refrigerator 100 and the refrigerator 200 can be shared. Therefore, there is no need to manufacture multiple molds, which can reduce manufacturing costs. Furthermore, the central opening 45b for the partition and the central opening 46b for the partition can also overlap. In addition, the front opening 45c for the partition and the front opening 46c for the partition can also overlap.

Furthermore, when the partition 27b is installed in the inner box 29, the upper part of the partition body 37b becomes the vegetable chamber 5, and the lower part becomes the freezing chamber 4. In this case, since the vegetable chamber 5 is sandwiched between the storage chambers with a lower temperature zone and is easily cooled, it is necessary to suppress the heat transfer between the upper and lower storage chambers and the vegetable chamber 5, so 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 foamed urethane 23, by arranging the vacuum insulation material 50 inside the partition body 37b, the thickness of the partition body 37b in the up-down direction can be reduced more than that of the partition body 37a. On the other hand, when the partition 27a is installed in the inner box 29, the lower part of the partition body 37a becomes the vegetable chamber 5, and the upper part becomes the freezing chamber 4. In this case, because the heat insulation performance of the partition body 37a can be lower than that of the vegetable chamber 5 above the freezing chamber 4, the vacuum insulation material 50 is not arranged inside the partition body 37a, but is filled with foamed urethane 23.

FIG. 25 is a longitudinal cross-sectional view of the A-A arrow portion of the separator 27b shown in FIG. 13 as viewed from the arrow direction. As shown in FIG. 25, the separator 27b includes a vacuum heat insulating material 50 inside the separator body 37b. The vacuum heat insulating material 50 is disposed in the internal space 37ba of the separator body 37b and is attached to the lower side surface 37bb of the separator body 37b from the inside through the connecting member 47. By disposing the vacuum heat insulating material 50 at the lower part of the separator body 37b, a portion of the front side of the upper side surface 37bc of the separator body 37b can be recessed, and a plurality of convex portions 37bd and concave portions 37be are formed on the upper side surface 37bc (see FIG. 13). By providing a recessed portion 37be on the upper side surface 37bc of the partition body 37b, the storage space of the vegetable chamber 5 can be expanded, and by providing a convex portion 37bd, a surface with a certain height can be formed in front and behind the upper side surface 37bc, so that the partition 27a and the partition 27b can share a jig for suppressing the deformation of the partition body 37b when the foaming urethane 23 is injected.

Furthermore, in the embodiment, in order to make the machine type A and the machine type B share the punching die for the mounting opening 33 of the inner box 29, as shown in FIG. 24, the shape of the mounting opening 33 of the inner box 29 is set to a size that can be connected to any one of the partition openings 45 and 46 of the partitions 27a and 27a, but it is not limited to this. The punching die for the mounting opening 33 used by the machine type A and the machine type B can also be different. In this case, the size of the mounting opening 33 of the inner box 29 can be reduced compared to the case where the machine type A and the machine type B share it, so the strength of the side surface of the recess 30 of the inner box 29 can be improved.

In the embodiment, the mounting opening 33 of the inner box 29 is set to a size that is connected to any one of the partition openings 45 and 46 of the partitions 27a and 27b, but the shape of the mounting opening 33 of the inner box 29 is not limited thereto. The mounting opening 33 may be divided into two types: an opening that is connected only to the partition opening 45 of the partition 27a of the model A and an opening that is connected only to the partition opening 46 of the partition 27b of the model B to form the inner box 29. Furthermore, when the position of the partition opening 45 when the partition 27a is mounted on the inner box 29 is separated from the position of the partition opening 46 when the partition 27b is mounted on 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 recessed portion 30 of the inner box 29.

FIG. 26 is a diagram showing the positional relationship between the opening for the mounting portion of the inner box 29 and the partition openings 45 and 46 of the partitions 27a and 27b when the partitions 27a and 27b are mounted on the left side surface 29a of the inner box 29 of the first modified example of the refrigerator 100 and 200 of the embodiment. FIG. 27 is a diagram showing the positional relationship between the opening for the mounting portion of the inner box 29 and the partition openings 45 and 46 of the partitions 27a and 27b when the partitions 27a are mounted on the left side surface 29a of the inner box 29 of the second modified example of the refrigerator 100 of the embodiment. FIG. 28 is a diagram showing the positional relationship between the opening for the mounting portion of the inner box 29 and the partition openings 45 and 46 of the partition 27b when the partition 27b is mounted on the left side 29a of the inner box 29 of the second variant of the refrigerator 200 of the embodiment. FIG. 29 is a diagram showing the positional relationship between the opening for the mounting portion of the inner box 29 and the partition openings 45 and 46 of the partition 27a and 27b when the partition 27a and 27b are mounted on the left side 29a of the inner box 29 of the third variant of the refrigerator 100 and 200 of the embodiment.

Furthermore, in Figure 24, the front opening 45c of the partition overlaps with the front opening 46c of the partition and the front opening 33c of the mounting portion, and the central opening 45b of the partition overlaps with the central opening 46b of the partition and the central opening 33b of the mounting portion, but the structure of the opening 33 of the mounting portion formed on the left side surface 29a is not limited to this. As shown in FIG. 26, the left side surface 29a may also form a mutually separated front opening 47c for the first mounting portion and a front opening 48c for the second mounting portion. When the partition 27a is mounted on the left side surface 29a of the inner box 29, the front opening 45c for the partition overlaps with the front opening 47c for the first mounting portion in a side view, and when the partition 27b is mounted on the left side surface 29a of the inner box 29, the front opening 46c for the partition overlaps with the front opening 48c for the second mounting portion in a side view. Furthermore, 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) are also configured in the same manner.

Further, as shown in Fig. 27 and Fig. 28, on the left side surface 29a, either the first mounting portion front opening 47c or the second mounting portion front opening 48c is selectively formed by punching a hole in accordance with the type of the partition. Then, as shown in Fig. 27, when the first mounting portion front opening 47c is formed, the partition 27a is mounted on the left side surface 29a of the inner box 29, and as shown in Fig. 28, when the second mounting portion front opening 48c is formed, the partition 27b is mounted on the left side surface 29a of the inner box 29. Furthermore, Regarding the central opening 47b for the first mounting part, the central opening 48b for the second mounting part, the rear opening for the first mounting part (not shown), and the rear opening for the second mounting part (not shown), similarly, two openings are provided at the top and the bottom according to the type of the partition. Even in this case, the shared inner box 29 can be used to provide two types of refrigerators 100 and 200 with different mounting positions corresponding to the partition 27a and the partition 27b.

Furthermore, in FIG. 24 , the front opening 33c for the mounting portion and the central opening 33b for the mounting portion have a longitudinal shape, but the shape of the mounting portion opening 33 is not limited thereto. As shown in FIG. 29 , the shapes of 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 also be non-longitudinally long, such as horizontally long, square, etc.

The refrigerator 100, 200 of the embodiment includes: a box body 101, which has an outer box 22, an inner box 29 and a heat insulating material and has a storage space for storing food inside, the outer box 22 forming an outer shell, the inner box 29 being configured to form a first space between the outer box 22 and having an injection opening for injecting the heat insulating material, and the heat insulating material is filled in the first space; and partitions 27a, 27b, which have a partition body 37a , a partition body 37b, a locking portion and partition openings 45, 46. The partition body 37a, the partition body 37b has a second space inside and divides the storage space into a plurality of storage chambers with different temperature zones. The locking portion fixes the partition body 37a, the partition body 37b to the inner box 29, and the partition openings 45, 46 are formed on the side surfaces of the partition body 37a, the partition body 37b. In addition, the inner box 29 has mounting parts 34a and 34b for mounting the stopper. When the stopper is mounted on the mounting parts 34a and 34b and the partition body 37a and 37b are fixed to the inner box 29, the mounting parts 34a and 34b have a mounting part opening 33 on the surface opposite to the side surface. The mounting part opening 33 is connected to the first space. When the inner box 29 is viewed from the side, the partition body 37a and 37b can be mounted on the inner box 29 at a position where the mounting part opening 33 and the partition openings 45 and 46 overlap above the mounting part opening 33 or at a position where the mounting part opening 33 and the partition openings 45 and 46 overlap below the mounting part opening 33.

According to the refrigerator 100, refrigerator 200 of the embodiment, when viewing the inner box 29 from the side, the partition body 37a, partition body 37b can be installed in the inner box 29 at a position where the mounting part opening 33 and the partition opening 45, partition opening 46 overlap above the mounting part opening 33 or at a position where the mounting part opening 33 and the partition opening 45, partition opening 46 overlap below the mounting part opening 33. Therefore, when the partition body 37a, 37b is installed at a position where the mounting opening 33 and the partition openings 45, 46 overlap above the mounting opening 33, and when the partition body 37a, 37b is installed at a position where the mounting opening 33 and the partition openings 45, 46 overlap below the mounting opening 33, the position of the partition body 37a, 37b in the up-down direction changes. Furthermore, in either case, since the mounting opening 33 and the partition openings 45, 46 overlap, the heat insulating material injected into the first space from the injection opening can be injected into the second space of the partition body 37a, 37b through the mounting opening 33 and the partition openings 45, 46 connected to the first space. In this way, the installation position of the partitions 27a and 27b installed in the box body 101 can be changed, so that appropriate compartments can be ensured in each storage room, which can improve the convenience of use for users. In addition, the installation position of the partitions 27a and 27b installed in the box body 101 can be changed, and regardless of the installation position of the partitions 27a and 27b installed in the box body 101, the heat insulating material injected into the first space from the injection opening can be injected into the second space of the partition body 37a and 37b, so that the mold for forming the inner box 29 can be shared, and there is no need to manufacture multiple molds, so the manufacturing cost can be suppressed. That is, the manufacturing cost can be suppressed while improving the convenience of use for users. Furthermore, since the structure of the housing 101 is manufactured individually for each model, compared with the previous structure in which a common housing 101 is manufactured regardless of the model, and the user can freely set the temperature of each storage room, it is possible to construct an optimal cooling structure and heat insulation structure that matches the position of each storage room, thereby suppressing power consumption and content storage loss.

In addition, in the refrigerators 100 and 200 of the embodiment, the plurality of mounting openings 33 include: a mounting rear opening 33a formed at the rear side of the inner box 29; a mounting front opening 33c formed at the front of the inner box 29 relative to the mounting rear opening 33a; and a plurality of mounting center openings 33b formed between the mounting rear opening 33a and the mounting front opening 33c, and the mounting rear opening 33a and the mounting front opening 33c have a larger area than each mounting center opening 33b.

According to the refrigerator 100, 200 of the embodiment, when the liquid heat insulating material is injected into the internal space 44 from the injection opening on the back of the inner box 29, the liquid heat insulating material flows into the front side of the inner box 29 in a highly fluid state. Therefore, by forming the front opening 33c for the mounting portion larger than the central opening 33b for the mounting portion, the heat insulating material in a highly fluid state injected from the back side of the inner box 29 can be fully filled into the interior of the partitions 27a and 27b. Furthermore, by forming the rear opening 33a for the mounting portion larger than the central opening 33b for the mounting portion, the heat insulating material whose fluidity drops to the rear opening 33a for the mounting portion can be filled into the rear of the interior of the partitions 27a and 27b.

In addition, in the refrigerator 100 of the embodiment, the partition 27a is installed on the first partition of the inner box 29 in a manner that the opening 33 for the mounting portion and the opening 45 for the partition are overlapped above the opening 33 for the mounting portion. When the first partition is installed on the inner box 29, a part of the opening 33 for the mounting portion is blocked by the lower side flange 36a of the locking portion of the first partition, the lower side flange 41a and the side surface of the partition body 37a. In the refrigerator 200 of the embodiment, the second partition is mounted on the inner box 29 in such a manner that the mounting opening 33 and the partition opening 46 overlap below the mounting opening 33. When the second partition is mounted on the inner box 29, a portion of the mounting opening 33 is blocked by the upper flange 35b and the upper flange 40b of the locking portion of the second partition and the side surface of the partition body 37b.

According to the refrigerator 100 and the refrigerator 200 of the embodiment, when the heat insulating material is injected into the interior of the partition 27a and the partition 27b, the heat insulating material can be prevented from leaking to the outside from the lower area E1 or the upper area E2 of the opening 33 for the mounting portion.
