DETAILED DESCRIPTION

[0030] Hereinafter, an embodiment of a refrigerator will be described with reference to the drawings. Figure 1 The refrigerator 10 shown as an example has a plurality of storage chambers 12, 13, 14, 15, and 16 formed inside a rectangular box-shaped heat-insulating box body 11 constituting its outer contour. Various storage items such as food can be stored inside the storage chambers 12, 13, 14, 15, and 16. Although detailed illustrations are omitted, the heat-insulating box body 11 has a structure in which a heat-insulating material is provided between an inner box and an outer box. As the heat-insulating member constituting the heat-insulating box body 11, various heat-insulating members such as vacuum insulation panels, foamed polyurethane, and heat-insulating molded bodies formed by molding heat-insulating materials can be applied.

[0031] In this case, the storage room 12 is a cold storage room maintained within the temperature range of the refrigerating temperature zone. Hereinafter, the storage room 12 is sometimes referred to as the "cold storage room 12". The refrigerating temperature zone is an example of a basic temperature zone, and the cold storage room 12 is an example of a basic storage room. In this case, the storage room 13 is a vegetable room maintained within the temperature range of the refrigerating temperature zone. Hereinafter, the storage room 13 is sometimes referred to as the "vegetable room 13". In this case, the storage room 14 is an ice-making room maintained within the temperature range of the freezing temperature zone. Hereinafter, the storage room 14 is sometimes referred to as the "ice-making room 14". In this case, the storage room 15 is a small freezing room maintained within the temperature range of the freezing temperature zone. Hereinafter, the storage room 15 is sometimes referred to as the "small freezing room 15". In this case, the storage room 16 is a large freezing room maintained within the temperature range of the freezing temperature zone. Hereinafter, the storage room 16 is sometimes referred to as the "large freezing room 16".

[0032] The refrigerating chamber 12 is a storage chamber arranged at the top among the multiple storage chambers 12, 13, 14, 15, and 16 provided in the refrigerator 10. The vegetable chamber 13 is provided at the lower side of the refrigerating chamber 12 and is provided so as to be located approximately in the middle of the vertical direction of the heat-insulating box body 11. The ice-making chamber 14 and the small freezer chamber 15 are provided at the lower side of the vegetable chamber 13 and are arranged in the horizontal direction of the refrigerator 10 in the heat-insulating box body 11. The large freezer chamber 16 is provided at the lower side of the ice-making chamber 14 and the small freezer chamber 15 in the heat-insulating box body 11. The large freezer chamber 16 is a storage chamber arranged at the bottom among the multiple storage chambers 12, 13, 14, 15, and 16 provided in the refrigerator 10.

[0033] The refrigerating chamber 12 has a rectangular opening on its front surface. The front surface opening of the refrigerating chamber 12 is opened and closed by two refrigerating chamber doors 12D[R] and 12D[L] that are rotatable in the left-right direction. The right refrigerating chamber door 12D[R] is an example of a first refrigerating chamber door, and the left refrigerating chamber door 12D[L] is an example of a second refrigerating chamber door. That is, the front surface opening of the refrigerating chamber 12 is formed as follows: it is opened and closed by at least two refrigerating chamber doors, in this case, the right refrigerating chamber door 12D[R] and the left refrigerating chamber door 12D[L]. In addition, the refrigerating chamber door may also be: a single refrigerating chamber door that opens and closes the front surface opening of the refrigerating chamber 12. In addition, the front surface opening of the refrigerating chamber 12 may also be a structure that is opened and closed by a plurality of 3 or more refrigerating chamber doors.

[0034] The size of the right door 12D[R] of the refrigerator compartment and the left door 12D[L] of the refrigerator compartment are the same in the vertical direction, but the size of the left and right direction is different. In this case, the size H1 of the right door 12D[R] of the refrigerator compartment is larger than the size H2 of the left door 12D[L] of the refrigerator compartment. When the front surface opening of the refrigerator compartment 12 is closed by the right door 12D[R] of the refrigerator compartment and the left door 12D[L] of the refrigerator compartment, the left end of the right door 12D[R] of the refrigerator compartment is located at a position further to the left than the center line L of the refrigerator 10 in the left and right direction, and the right end of the left door 12D[L] of the refrigerator compartment is also located at a position further to the left than the center line L of the refrigerator 10 in the left and right direction.

[0035] The longitudinal partition plate 12S is foldably provided at the right end of the left door 12D[L] of the refrigerating chamber. When the front opening of the refrigerating chamber 12 is closed by the right door 12D[R] and the left door 12D[L] of the refrigerating chamber, the longitudinal partition plate 12S blocks the gap between the right door 12D[R] and the left door 12D[L] of the refrigerating chamber. Thus, the longitudinal partition plate 12S prevents the cold air in the refrigerating chamber 12 from flowing out from the gap between the right door 12D[R] and the left door 12D[L].

[0036] The vegetable compartment 13 has a rectangular opening on its front surface. The front opening of the vegetable compartment 13 is opened and closed by a storage compartment door that can move in the front-to-back direction, so-called a drawer-type vegetable compartment door 13D. The ice compartment 14 has a rectangular opening on its front surface. The front opening of the ice compartment 14 is opened and closed by a storage compartment door that can move in the front-to-back direction, so-called a drawer-type ice compartment door 14D. The small freezer compartment 15 has a rectangular opening on its front surface. The front opening of the small freezer compartment 15 is opened and closed by a storage compartment door that can move in the front-to-back direction, so-called a drawer-type small freezer compartment door 15D. The large freezer compartment 16 has an opening on its front surface. The front opening of the large freezer compartment 16 is opened and closed by a storage compartment door that can move in the front-to-back direction, so-called a drawer-type large freezer compartment door 16D.

[0037] Also like Figure 2 As shown in the example, a fresh-keeping room 100 is provided in the refrigerating room 12. In this case, the fresh-keeping room 100 is provided in the lower part of the refrigerating room 12. The fresh-keeping room 100 is an example of a special storage room. The fresh-keeping room 100 is provided in the refrigerating room 12, and therefore, can be cooled to a refrigerating temperature zone in the same manner as the refrigerating room 12. However, the fresh-keeping room 100 can also be cooled to a fresh-keeping temperature zone different from the refrigerating temperature zone. The fresh-keeping temperature zone is an example of a special temperature zone. In this case, the fresh-keeping temperature zone is assumed to be a temperature zone lower than the refrigerating temperature zone.

[0038] A plurality of containers capable of storing stored items are stored in the fresh food compartment 100 so as to be pulled out in the front-rear direction. In this case, three containers are stored, namely, a large container 101, a medium container 102, and a small container 103. The large container 101, the medium container 102, and the small container 103 are pulled out in the fresh food compartment 100. The user pulls the large container 101, the medium container 102, and the small container 103 forward, thereby enabling the stored items to be taken in and out of the large container 101, the medium container 102, and the small container 103.

[0039] In this case, the large container 101 is arranged in the upper layer of the fresh food compartment 100. The middle container 102 and the small container 103 are arranged in the lower layer of the fresh food compartment 100, and are arranged side by side in the left-right direction below the large container 101. In this case, when viewed from the front side of the refrigerator 10, the middle container 102 is arranged on the right side of the lower layer of the fresh food compartment 100, and the small container 103 is arranged on the left side of the lower layer of the fresh food compartment 100. In addition, the following structure can also be formed: when viewed from the front side of the refrigerator 10, the middle container 102 is arranged on the left side of the lower layer of the fresh food compartment 100, and the small container 103 is arranged on the right side of the lower layer of the fresh food compartment 100.

[0040] In the lower layer of the cold fresh room 100, a water supply box 104 is accommodated in a position further to the left than the small container 103 in a manner that can be pulled out in the front-back direction. The water supply box 104 is a box that can store water for ice making. Although detailed illustrations are omitted, the water stored in the water supply box 104 is supplied to the ice maker in the ice making room 14 by a pump and a water supply pipe.

[0041] The large container 101 is an example of a first container, and in this case, is formed into a shallow rectangular box with an open upper surface. Although the front surface of the large container 101 is provided with a handle for the user to hang his fingers, the large container 101 is formed into a structure in which the front surface opening of the upper space is substantially open when the large container 101 is accommodated in the upper space of the cold and fresh compartment 100. Therefore, even if the user does not pull the large container 101 out of the cold and fresh compartment 100, the stored items can be put in and out of the large container 101 to some extent.

[0042] The middle container 102 is an example of a second container, and in this case, is formed into a deep rectangular box shape with an open upper surface. The front surface portion of the middle container 102 is wall-shaped, and is formed into a structure in which the front surface opening of the lower space is substantially closed when the middle container 102 is accommodated in the lower space of the cold fresh food compartment 100.

[0043] The small container 103 is an example of a third container, and in this case, is formed into a deep rectangular box shape with an open upper surface. The front surface portion of the container 103 is also wall-shaped, and is formed into a structure in which the front surface opening of the lower space is substantially closed when the small container 103 is accommodated in the lower space of the cold fresh room 100.

[0044] The storage spaces of the large container 101, the medium container 102, and the small container 103 are different in size. In this case, the storage space of the large container 101 is the largest among the multiple containers 101, 102, and 103. The storage space of the small container 103 is the smallest among the multiple containers 101, 102, and 103. The storage space of the medium container 102 is smaller than the storage space of the large container 101, and larger than the storage space of the small container 103.

[0045] like Figure 3As shown in the example, the large container 101 is opposed to both the right door 12D[R] and the left door 12D[L] of the refrigerator compartment 12 in a state where the front surface opening of the refrigerator compartment 12 is closed. In a state where the front surface opening of the refrigerator compartment 12 is closed by the right door 12D[R] and the left door 12D[L] of the refrigerator compartment, the left end of the large container 101 is located at a position that is further inside than the left end of the left door 12D[L] of the refrigerator compartment, that is, at a position that is at a center side in the left-right direction, and the right end of the large container 101 is located at a position that is further inside than the right end of the right door 12D[R] of the refrigerator compartment, that is, at a position that is at a center side in the left-right direction. That is, the left-right dimension H3 of the large container 101 is smaller than the dimension H4 between the left end of the left door 12D[L] of the refrigerator compartment and the right end of the right door 12D[R] of the refrigerator compartment in a closed state.

[0046] like Figure 4 As shown in the example, the middle container 102 is opposite to one of the storage door of the refrigerator compartment right door 12D[R] and the refrigerator compartment left door 12D[L], which is in a state where the front surface opening of the refrigerator compartment 12 is closed, that is, the refrigerator compartment right door 12D[R]. When the front surface opening of the refrigerator compartment 12 is closed by the refrigerator compartment right door 12D[R] and the refrigerator compartment left door 12D[L], the left end of the middle container 102 is located at a position that is more inward than the left end of the refrigerator compartment right door 12D[R], that is, at a position that is more inward than the right end of the refrigerator compartment right door 12D[R], that is, at a position that is more inward than the right end of the refrigerator compartment right door 12D[R], that is, at a position that is more inward than the right end of the refrigerator compartment right door 12D[R]. That is, the left-right dimension H5 of the middle container 102 is smaller than the dimension H1 between the left and right ends of the refrigerator compartment right door 12D[R] in the closed state.

[0047] The small container 103 is opposite to the other storage door, in this case, the left door 12D[L] of the refrigerator compartment, of the right door 12D[R] and the left door 12D[L] of the refrigerator compartment, which are in a state of closing the front surface opening of the refrigerator compartment 12. When the front surface opening of the refrigerator compartment 12 is closed by the right door 12D[R] and the left door 12D[L] of the refrigerator compartment, the left end of the small container 103 is located at a position that is further inside than the left end of the left door 12D[L] of the refrigerator compartment, i.e., at a position on the central side in the left-right direction, and the right end of the small container 103 is located at a position that is further inside than the right end of the left door 12D[L] of the refrigerator compartment, i.e., at a position on the central side in the left-right direction. That is, the left-right dimension H6 of the small container 103 is smaller than the dimension H2 between the left and right ends of the left door 12D[L] of the refrigerator compartment in a closed state.

[0048] like Figure 5As shown in the example, a plate-shaped partition member 105 is provided above the large container 101. The fresh food compartment 100 is formed by a space below the partition member 105. The partition member 105 partitions the space between the partition member 105 and the large container 101 from the refrigerating compartment 12 as a part of the fresh food compartment 100.

[0049] The height of the partition member 105 can be adjusted above the large container 101. In more detail, the partition member 105 is placed on a protrusion (not shown) provided on the inner side of the refrigerating chamber 12 in a detachable manner. Moreover, the protrusion (not shown) is formed in multiple layers with a predetermined interval in the vertical direction. The partition member 105 is selectively mounted at any height position in the multiple protrusions. Therefore, the height of the partition member 105 can be appropriately adjusted above the large container 101.

[0050] In addition, the unillustrated protrusion supporting the partition member 105 may be, for example, a reinforcing rib-like protrusion integrally provided on the inner box forming the inner surface of the heat-insulating box body 11, or a fixing part installed on the inner box.

[0051] A plurality of shelf members 12T are provided in a detachable manner in the refrigerating chamber 12. Stored goods can be placed on the upper surface of the shelf members 12T. A partition member 105 is provided as a structural element different from the above-mentioned shelf members 12T. However, the partition member 105 can also be defined as a structural element that functions as a shelf member of the lowest layer in the refrigerating chamber 12, and stored goods can also be placed on the upper surface of the partition member 105.

[0052] The upper region in the fresh-keeping room 100 is a structure that does not include a fresh-keeping room door that makes the fresh-keeping room 100 roughly a closed space. That is, the upper region in the fresh-keeping room 100 is formed as an open space whose front surface opening is always open. Therefore, the refrigerator 10 is formed as follows: when both the right door 12D[R] and the left door 12D[L] of the refrigerator are open, the entire space between the large container 101 and the partition member 105 is open to the front side. In addition, the refrigerator 10 is formed as follows: when at least one of the right door 12D[R] and the left door 12D[L] of the refrigerator is open, at least a portion of the space between the large container 101 and the partition member 105, that is, the portion opposite to the open refrigerator door, is open to the front side.

[0053] In addition, the lower area of ​​the fresh food compartment 100 is also not provided with a fresh food compartment door that makes the fresh food compartment 100 substantially a closed space. However, the front surface of the middle container 102 and the front surface of the small container 103 accommodated in the lower space of the fresh food compartment 100 are formed into a structure that can function as a fresh food compartment cover that closes the lower space of the fresh food compartment 100.

[0054] like Figure 6 For example, when the left refrigerator door 12D[L] closes the front opening of the refrigerator compartment 12, and the right refrigerator door 12D[R] opens the front opening of the refrigerator compartment 12 by an opening angle of, for example, 90 degrees or more, Figure 7 As shown in the example, the small container 103 cannot be pulled out forward, but the middle container 102 can be pulled out forward.

[0055] like Figure 8 For example, when the right door 12D[R] of the refrigerator compartment closes the front opening of the refrigerator compartment 12, and the left door 12D[L] of the refrigerator compartment opens the front opening of the refrigerator compartment 12 by an opening angle of, for example, 90 degrees or more, Fig. 9 As shown in the example, the middle container 102 cannot be pulled out forward, but the small container 103 can be pulled out forward.

[0056] The large container 101, the medium container 102, and the small container 103 are each configured to be able to adjust the cooling capacity. Next, this point will be described in detail. Fig.10 As shown in the example, the refrigerator 10 includes a cooler compartment 200. In this case, the cooler compartment 200 is provided on the rear side of the vegetable compartment 13. In the cooler compartment 200, a cooler 201 and a blower fan 202 are accommodated.

[0057] The cooler 201, together with a compressor (not shown) and the like, constitutes a well-known refrigeration cycle mechanism, generating cold air for cooling the refrigerator compartment 12 and the vegetable compartment 13. The cooler 201 is surrounded by a heat insulating member 203 in the cooler compartment 200. In this case, the heat insulating member 203 is opposed to the upper portion and the left and right side portions of the cooler 201, but is not opposed to the lower portion of the cooler 201. A guide groove member for receiving the defrost water generated by the cooler 201 is provided below the cooler 201.

[0058] The air supply fan 202 delivers the cold air generated by the cooler 201 into the refrigerating chamber 12 and even into the vegetable chamber 13. The refrigerator 10 includes a plurality of air supply fans 202, and in this case, includes two air supply fans 202. The plurality of air supply fans 202 are assembled in a portion of the heat insulating member 203 that is opposite to the upper portion of the cooler 201. The plurality of air supply fans 202 are arranged so that the rotating shafts of the fans are in the up-down direction. The plurality of air supply fans 202 are arranged in a row in the left-right direction.

[0059] In the upper part of the cooler room 200, a refrigerator duct 210 is provided extending upward along the rear surface of the refrigerator room 12. The refrigerator duct 210 is provided with a plurality of cold air outlets 211 for the refrigerator room. In addition, the refrigerator duct 210 is provided with a plurality of cold air outlets as cold air outlets for the fresh air room, in which case, a large container cold air outlet 221, a medium container cold air outlet 222, and a small container cold air outlet 223 are provided.

[0060] The cold air generated by the cooler 201 passes through the refrigerator duct 210 due to the air supply of the air supply fan 202, and is supplied to the refrigerating chamber 12 from the refrigerating chamber cold air outlet 211. Thus, the refrigerating chamber 12 is cooled to a temperature within a predetermined refrigerating temperature range.

[0061] In addition, the cold air generated by the cooler 201 passes through the refrigerator duct 210 due to the air supply effect of the air supply fan 202, and is supplied from the large container cold air outlet 221 to the large container 101 in the cold fresh temperature zone. As a result, the inside of the large container 101 is cooled to a temperature range within a predetermined cold fresh temperature zone. In addition, in the present embodiment, a plurality of, in this case, two large container cold air outlets 221 are arranged to have a predetermined interval in the vertical direction. In addition, the opening area of ​​the upper large container cold air outlet 221 is larger than the opening area of ​​the lower large container cold air outlet 221.

[0062] In addition, the cold air generated by the cooler 201 passes through the refrigerator duct 210 due to the air supply of the air supply fan 202, and is supplied to the middle container 102 in the cold fresh room 100 from the middle container cold air outlet 222. Thus, the inside of the middle container 102 is cooled to a temperature within the specified cold fresh temperature range.

[0063] In addition, the cold air generated by the cooler 201 passes through the refrigerator duct 210 due to the air supply of the air supply fan 202, and is supplied from the small container cold air outlet 223 to the small container 103 in the cold fresh room 100. As a result, the inside of the small container 103 is cooled to a temperature within the specified cold fresh temperature range.

[0064] Also like Fig.11 and Fig.12As shown in the example, the refrigerator internal duct 210 is provided with a cold air supply adjustment unit 300 capable of adjusting the amount of cold air supplied to the refrigerating chamber 12, the large container 101, the medium container 102, and the small container 103. The cold air supply adjustment unit 300 is an example of an adjustment unit, and in this case, it is provided with a double damper 310 and a single damper 320.

[0065] The double damper 310 is a structure having a plurality of dampers, in this case, a large damper 311 and a medium damper 312. The double damper 310 is a structure having a plurality of openings, in this case, a large opening 313 and a medium opening 314. The large opening 313 is located below the large container cold air outlet 221. The medium opening 314 is located below the medium container cold air outlet 222.

[0066] The large opening 313 is opened in a rectangular shape that is long in the left-right direction. The large air door 311 is formed in a rectangular plate shape that is long in the left-right direction and has a size that can close the large opening 313. The middle opening 314 is opened in a rectangular shape that is long in the left-right direction. The middle air door 312 is formed in a rectangular plate shape that is long in the left-right direction and has a size that can close the middle opening 314.

[0067] The large damper 311 and the medium damper 312 are configured to be rotatable by a common motor (not shown) provided in the double damper 310. That is, the double damper 310 is configured to be able to rotate a plurality of dampers, in this case two dampers 311 and 312, by a single motor.

[0068] The double adjustment damper 310 can make the opening degrees of the large damper 311 and the medium damper 312 different or the same by adjusting the transmission mechanism (not shown) for transmitting the rotational force of the motor to the large damper 311 and the medium damper 312.

[0069] The large air door 311 is an example of a switching component, and the double adjustment air door 310 controls the driving of the motor not shown in the figure to switch the large air door 311 to a blocking state and a allowing state. The blocking state is an example of a first state, and is a state in which the cold air generated by the cooler 201 is blocked from flowing to the cold air outlet 221 for the large container. That is, the blocking state is a state in which the large air door 311 closes the large opening 313. On the other hand, the allowing state is an example of a second state, and is a state in which the cold air generated by the cooler 201 is allowed to flow to the cold air outlet 221 for the large container. That is, the allowing state is a state in which the large air door 311 opens the large opening 313.

[0070] The middle air door 312 is an example of a switching component, and the double adjustment air door 310 controls the driving of the motor not shown in the figure to switch the middle air door 312 to a blocking state and a allowing state. The blocking state is an example of a first state, and is a state in which the cold air generated by the cooler 201 is blocked from flowing to the cold air outlet 222 for the middle container. That is, the blocking state is a state in which the middle air door 312 closes the middle opening 314. On the other hand, the allowing state is an example of a second state, and is a state in which the cold air generated by the cooler 201 is allowed to flow to the cold air outlet 222 for the middle container. That is, the allowing state is a state in which the middle air door 312 opens the middle opening 314.

[0071] The single damper 320 is formed as a structure including one small damper 321. The single damper 320 has one small opening 322. The small opening 322 is located below the small container cold air outlet 223.

[0072] The small opening 322 is opened in a rectangular shape that is long in the left-right direction. The small damper 321 is formed in a rectangular plate shape that is long in the left-right direction and has a size that can close the small opening 322 .

[0073] The small damper 321 is configured to be rotatable by a single motor (not shown) provided in the single damper 320. That is, the single damper 320 is configured to be rotatable by a single motor.

[0074] The small air door 321 is an example of a switching component, and the small air door 321 can be switched between a blocking state and a allowing state by controlling the driving of the motor (not shown) by the single air door 320. The blocking state is an example of the first state, and is a state in which the cold air generated by the cooler 201 is blocked from flowing to the cold air outlet 223 for the small container. That is, the blocking state is a state in which the small air door 321 closes the small opening 322. On the other hand, the allowing state is an example of the second state, and is a state in which the cold air generated by the cooler 201 is allowed to flow to the cold air outlet 223 for the small container. That is, the allowing state is a state in which the small air door 321 opens the small opening 322.

[0075] The cold air supply adjustment unit 300 is disposed between the cooler 201 and the plurality of cold air outlets 221, 222, and 223, and a partition rib 330 is disposed between the plurality of cold air outlets 221, 222, and 223. Thus, the cold air passing through the large opening 313 can be easily guided to the cold air outlet 221 for the large container, the cold air passing through the middle opening 314 can be easily guided to the cold air outlet 222 for the middle container, and the cold air passing through the small opening 322 can be easily guided to the cold air outlet 223 for the small container.

[0076] According to the refrigerator 10, the amount or intensity of cold air supplied to the large container 101, the medium container 102, and the small container 103 can be adjusted by appropriately changing the opening of the large air door 311, the medium air door 312, and the small air door 321. Thus, the cooling capacity of the large container 101, the medium container 102, and the small container 103 can be adjusted respectively.

[0077] In addition, if Fig.13 As shown in the example, regarding the middle wind door 312, it is configured that at least one end, in this case, the front end, of the middle wind door 312 switched to the permitted state overlaps with the middle container cold air outlet 222 in the blowing direction R of cold air. That is, the front end of the middle wind door 312 switched to the permitted state is arranged at a position higher than the lower end of the middle container cold air outlet 222. In addition, it is configured that in the process of switching the middle wind door 312 from the blocking state to the permitted state, at least one end, in this case, the front end, of the middle wind door 312 moves away from the middle container cold air outlet 222 side to the opposite side of the middle container cold air outlet 222.

[0078] In addition, the small air door 321 is also configured such that at least one end, in this case, the front end, of the small air door 321 switched to the permitted state overlaps with the small container cold air outlet 223 in the blowing direction R of cold air. That is, the front end of the small air door 321 switched to the permitted state is arranged at a position higher than the lower end of the small container cold air outlet 223. In addition, the following structure is formed: in the process of switching the small air door 321 from the blocking state to the permitted state, at least one end, in this case, the front end, of the small air door 321 moves away from the small container cold air outlet 223 side to the opposite side of the small container cold air outlet 223.

[0079] like Figures 10 to 12 As shown in the example, a cold air return port 401 is provided at the rear of the partition wall 400 that separates the refrigerating chamber 12 and the fresh cold chamber 100 from the vegetable chamber 13 so as to be located on the side of the refrigerator internal duct 210. The cold air return port 401 is provided on the rear surface side of the partition wall 400 that constitutes the bottom wall of the refrigerating chamber 12 and the fresh cold chamber 100, and is opposed to the cooler chamber 200 in the vertical direction. In this case, the cold air return port 401 is opposed to the upper surfaces of the left and right ends of the cooler chamber 200.

[0080] In addition, the cold air return port 401 is provided at a position offset to the left and right sides of the cooler 201 relative to the cooler 201 in the cooler chamber 200. The cold air return port 401 has a function of returning the cold air supplied to the refrigerating chamber 12 or the fresh cold chamber 100 to the cooler 201, and in this case, is formed as an opening composed of a plurality of slits. In this case, the plurality of slits extend in the front-rear direction, respectively, and are arranged at a predetermined interval in the left-right direction.

[0081] In addition, an opening 230 composed of a plurality of slits is provided on the upper surface of the left and right ends of the cooler chamber 200 in a manner opposite to the cold air return port 401. Furthermore, a cold air return passage 232 is formed below the opening 230 in the cooler chamber 200 in a manner located between a cover 231 forming the outer contour of the cooler chamber 200 and the heat insulating member 203.

[0082] like Fig.14 and Fig.15 As shown by the black arrow in the figure, the cold air supplied to the refrigerating chamber 12 or the fresh cold chamber 100 is supplied to the vegetable chamber 13 via the cold air return port 401, thereby the vegetable chamber 13 is also cooled by the cold air. That is, the refrigerator 10 is formed as follows: the cold air supplied to the refrigerating chamber 12 or the fresh cold chamber 100 is then transported to the vegetable chamber 13 to cool the vegetable chamber 13.

[0083] like Fig.16 As shown by the black arrow in the middle, a cold air recovery port 240 is provided at the lower part of the heat insulating member 203. In the vegetable chamber 13, the cold air passing through the cold air return port 401 enters the cooler chamber 200 from the opening 230, flows through the cold air return passage 232, and forms a cold air flow returning from the cold air recovery port 240 to the cooler 201. As a result, it is difficult for the cold air to directly flow toward the stored items in the vegetable chamber 13, and therefore, it is easy to maintain the temperature or humidity in the vegetable chamber 13 suitable for the stored items such as vegetables.

[0084] In addition, a slight gap is formed between the cold air return port 401 and the opening 230 , so that a part of the cold air passing through the cold air return port 401 can also flow into the vegetable compartment 13 without flowing into the cooler compartment 200 .

[0085] In addition, the partition wall 400 is mainly made of resin material, and has a lower heat insulation property than a heat insulating wall with a heat insulating member. Therefore, the cold air in the refrigerating chamber 12 or the fresh cold chamber 100 can be used to indirectly cool the vegetable chamber 13 through the partition wall 400, and even if the cold air is difficult to directly flow toward the stored items in the vegetable chamber 13, the vegetable chamber 13 can be kept cooled to an appropriate temperature.

[0086] The cold air returned from the cold air recovery port 240 to the cooler chamber 200 is cooled again by the cooler 201, and is supplied to the refrigerating chamber 12 or the fresh cold chamber 100, and then transported to the vegetable chamber 13. The following structure is formed: by repeatedly circulating this cold air, the refrigerating chamber 12, the fresh cold chamber 100, and the vegetable chamber 13 are cooled to a temperature range within a predetermined temperature zone.

[0087] According to the refrigerator 10 involved in the present disclosure, the fresh food compartment 100 is provided with a large container 101 on the upper layer, and a medium container 102 and a small container 103 arranged in the left-right direction on the lower layer. Moreover, the structure is formed as follows: the medium container 102 is opposite to the right door 12D[R] of the refrigerator compartment in a closed state, and the small container 103 is opposite to the left door 12D[L] of the refrigerator compartment in a closed state. Moreover, in a state where the front surface opening of the refrigerator compartment 12 is closed by the right door 12D[R] of the refrigerator compartment and the left door 12D[L] of the refrigerator compartment, the left and right ends of the medium container 102 are located at a position closer to the inside than the left and right ends of the right door 12D[R] of the refrigerator compartment in a closed state opposite to the container 102, and the left and right ends of the small container 103 are located at a position closer to the inside than the left and right ends of the left door 12D[L] of the refrigerator compartment in a closed state opposite to the container 103.

[0088] According to this structural example, in a refrigerator 10 having a structure in which a special storage room, such as a fresh-keeping room 100, is provided in a refrigerating room 12, and a front surface opening of the refrigerating room 12 is opened and closed by a right door 12D[R] and a left door 12D[L] of the refrigerating room, stored objects can be taken in and out of the fresh-keeping room 100 even when only one of the right door 12D[R] and the left door 12D[L] of the refrigerating room is open.

[0089] That is, when the left door 12D[L] of the refrigerator is closed and the right door 12D[R] of the refrigerator is open, the user can move stored items in and out of the portion of the large container 101 corresponding to the right door 12D[R] of the refrigerator, and can also move stored items in and out of the middle container 102.

[0090] In addition, when the right door 12D[R] of the refrigerator is closed and the left door 12D[L] of the refrigerator is open, the user can move stored items in and out of the portion of the large container 101 corresponding to the left door 12D[L] of the refrigerator, and can also move stored items in and out of the small container 103.

[0091] In addition, according to the refrigerator 10, the large container 101, the middle container 102, and the small container 103 are respectively configured to be able to adjust the cooling capacity. According to this structural example, the large container 101, the middle container 102, and the small container 103 can be switched to cooling modes of different temperature zones and used, and a structure with good convenience for the user can be provided.

[0092] As the switchable cooling modes, for example, a fresh-keeping mode for cooling to a temperature zone near 0 degrees, a local mode for cooling to a temperature zone near -3 degrees, and a refrigeration mode for cooling to a temperature zone near 5 degrees can be realized. In addition, a heater is provided on the bottom of the container, so that a summer vegetable cooling mode for cooling to a temperature zone near 10 degrees can be realized. In addition, a heat insulator is provided around the container, so that a soft freezing mode for cooling to a temperature zone near -9 degrees can be realized.

[0093] In addition, according to the refrigerator 10, the cold air supply adjustment unit 300 can adjust the amount of cold air supplied to the large container 101, the medium container 102, and the small container 103, respectively, and the cold air supply adjustment unit 300 appropriately changes the opening of the large air door 311, the medium air door 312, and the small air door 321 to adjust the cooling capacity of the large container 101, the medium container 102, and the small container 103. Thus, the cooling capacity of the large container 101, the medium container 102, and the small container 103 can be adjusted with high precision and fineness.

[0094] In addition, according to the refrigerator 10, the middle air door 312 is configured such that at least one end of the middle air door 312 switched to the permitted state, in this case, the front end, overlaps with the middle container cold air outlet 222 in the cold air blowing direction R. In addition, the small air door 321 is also configured such that at least one end of the small air door 321 switched to the permitted state, in this case, the front end, overlaps with the small container cold air outlet 223 in the cold air blowing direction R.

[0095] According to this structural example, the distance between the middle air door 312 and the middle container cold air outlet 222 and the distance between the small air door 321 and the small container cold air outlet 223 can be shortened as much as possible, and the size of the cold air supply adjustment unit 300 can be suppressed. In addition, cold air can be blown out from the middle container cold air outlet 222 or the small container cold air outlet 223 while maintaining the momentum of the cold air as much as possible.

[0096] In addition, according to the refrigerator 10, the following structure is formed: during the process of switching the middle air door 312 from the blocking state to the allowing state, at least one end of the middle air door 312, in this case, the front end, moves away from the side of the middle container cold air outlet 222 toward the opposite side of the middle container cold air outlet 222. In addition, the following structure is formed: during the process of switching the small air door 321 from the blocking state to the allowing state, at least one end of the small air door 321, in this case, the front end, moves away from the side of the small container cold air outlet 223 toward the opposite side of the small container cold air outlet 223.

[0097] According to this structural example, it is possible to prevent the front end of the middle air door 312 switched from the blocking state from closing the entire or a part of the middle container cold air outlet 222, thereby allowing the cold air to smoothly flow out of the middle container cold air outlet 222. In addition, it is possible to prevent the front end of the small air door 321 switched from the blocking state from closing the entire or a part of the small container cold air outlet 223, thereby allowing the cold air to smoothly flow out of the small container cold air outlet 223.

[0098] In addition, according to the refrigerator 10, the cold air return port 401 is provided on the rear surface side of the bottom wall of the refrigerating chamber 12 and the fresh cold chamber 100, and is opposed to the upper surfaces of the left and right ends of the cooler chamber 200 in the vertical direction. In addition, the upper surfaces of the left and right ends of the cooler chamber 200 are provided with openings 230 connected to the cooler 201. According to this structural example, the cold air passing through the cold air return port 401 can be smoothly guided from the opening 230 toward the cooler 201.

[0099] In addition, according to the refrigerator 10, the cold air return port 401 is provided on the left and right sides of the cooler 201. According to this structural example, the space on the left and right sides of the cooler 201 can be flexibly used to allow the cold air passing through the cold air return port 401 to flow. In addition, according to the refrigerator 10, a cold air return passage 232 is formed in the space on the left and right sides of the cooler 201, and the cold air return passage 232 is located below the cold air return port 401 and is opposite to the cold air return port 401 in the vertical direction. According to this structural example, the cold air passing through the cold air return port 401 can be efficiently returned to the cooler 201 through the cold air return passage 232.

[0100] In addition, the refrigerator 10 may have a structure in which the cold air return port 401 or the cold air return passage 232 is provided on at least one of the left and right sides of the cooler 201 .

[0101] In addition, according to the refrigerator 10, a partition member 105 is provided above the large container 101. The partition member 105 partitions the space between the partition member 105 and the large container 101 from the refrigerating chamber 12 as a part of the fresh food chamber 100. In addition, the refrigerator 100 has a structure in which at least a part of the space between the large container 101 and the partition member 105 is opened to the front side when at least one of the refrigerating chamber right door 12D[R] and the refrigerating chamber left door 12D[L] is opened.

[0102] According to this structural example, when at least one of the refrigerator compartment right door 12D[R] and the refrigerator compartment left door 12D[L] is open, the user can move the stored objects in and out of at least a portion of the large container 101. Therefore, compared with the existing structure in which the stored objects cannot be moved in and out of the cold storage compartment unless the two refrigerator compartment doors are opened, a structure with good usability can be provided.

[0103] In addition, according to the refrigerator 10, the height of the partition member 105 can be adjusted above the large container 101. According to this structural example, the storage capacity of the upper region in the fresh food compartment 100 can be appropriately expanded or reduced, thereby providing a more convenient structure.

[0104] In addition, the present disclosure is not limited to the above-mentioned one embodiment, and various modifications and extensions can be made within the scope not departing from the gist of the present disclosure.

[0105] The refrigerator 10 can be formed into a first deformation structure without the longitudinal partition plate 12S. In addition, the refrigerator 10 can be formed into the following second deformation structure: the longitudinal partition plate 12S can be connected to any one of the refrigerator right door 12D[R] and the refrigerator left door 12D[L], the longitudinal partition plate 12S is connected to the storage room door that is opened first among the refrigerator right door 12D[R] and the refrigerator left door 12D[L], and the longitudinal partition plate 12S is not connected to the storage room door that is opened later or the storage room door that is not opened. According to the above-mentioned first deformation structure or the second deformation structure, if the opposite storage room door is opened, any of the middle containers 102 and small containers 103 arranged on the left and right sides of the lower layer of the fresh food room 100 can be pulled out without interfering with other storage room doors or the longitudinal partition plate 12S.

[0106] like Figure 4 As shown in the example, the left end of the middle container 102 of the refrigerator 10 is located further to the left than the right end of the longitudinal partition plate 12S. Therefore, even if the right door 12D[R] of the refrigerator compartment is opened, when the left door 12D[L] of the refrigerator compartment provided with the longitudinal partition plate 12S is closed, if the middle container 102 is pulled forward, the left end of the middle container 102 may touch the longitudinal partition plate 12S.

[0107] Therefore, if Fig.17 For example, the refrigerator 10 may be configured such that the boundary wall 106 separating the middle container 102 and the small container 103 is located further to the right than the right end of the longitudinal partition plate 12S. Thus, the left end of the middle container 102 is located further to the right than the right end of the longitudinal partition plate 12S, and when the middle container 102 is pulled forward, the left end of the middle container 102 can be prevented from touching the longitudinal partition plate 12S.

[0108] The refrigerator 10 can be structured as follows: when the front surface opening of the refrigerating chamber 12 is closed by the refrigerating chamber right door 12D[R] and the refrigerating chamber left door 12D[L], the left and right ends of at least any one of the middle container 102 and the small container 103 are located further inward than the left and right ends of the storage chamber door opposite to the container.

[0109] The refrigerator 10 may be configured as follows, that is, at least the left and right ends of the container whose storage space is larger than the storage space of the other container among the middle container 102 and the small container 103 are located at a position closer to the inside than the left and right ends of the storage chamber door opposite to the container. That is, in the structural example of the refrigerator 10 disclosed in the present invention, it may be configured as follows, that is, the left and right ends of the middle container 102 whose storage space is larger than the small container 103 are located at a position closer to the inside than the left and right ends of the storage chamber door opposite to the container. In addition, the refrigerator 10 may be configured as follows, that is, at least the left and right ends of the container whose storage space is smaller than the storage space of the other container among the middle container 102 and the small container 103 are located at a position closer to the inside than the left and right ends of the storage chamber door opposite to the container. That is, in the structural example of the refrigerator 10 disclosed in the present invention, it may be configured as follows, that is, the left and right ends of the small container 103 whose storage space is smaller than the middle container 102 are located at a position closer to the inside than the left and right ends of the storage chamber door opposite to the container.

[0110] In addition, if Fig.18 For example, the refrigerator 10 may be configured to include one air supply fan 202 instead of a plurality of air supply fans 202. In this case, the refrigerator 10 may include an air supply fan 202 with higher air supply performance as the number of air supply fans 202 is reduced. Fig.18 In the illustrated configuration example, the air supply fan 202 is arranged such that the rotation axis of the fan is along the front-rear direction. Fig.18 In the structural example shown in the example, the air supply fan 202 can also be configured so that the rotation axis of the fan is along the up-down direction. In addition, although detailed illustrations are omitted, in the structural example with multiple air supply fans 202, the multiple air supply fans 202 can be configured so that the rotation axis of the fan is along the front-back direction.

[0111] The cold air supply adjustment unit 300 is formed as follows: when viewed from the front side of the refrigerator 10, it is provided with a double damper 310 on the right side and a single damper 320 on the left side. However, the cold air supply adjustment unit 300 may also be formed as follows: when viewed from the front side of the refrigerator 10, it is provided with a double damper 310 on the left side and a single damper 320 on the right side.

[0112] According to the cold air supply adjustment unit 300, it is formed as: a structure with a double adjustable damper 310 that can rotate two dampers 311 and 312. Therefore, compared with a structure with three single adjustable dampers that can rotate one damper, the increase in the number of components can be suppressed. In addition, the overall compactness of the cold air supply adjustment unit 300 can be achieved.

[0113] In addition, the cold air supply adjustment unit 300 may be configured as follows: a three-adjustable damper that can rotate three dampers. According to this structural example, the increase in the number of components can be further suppressed, and the overall compactness of the cold air supply adjustment unit 300 can be further achieved. However, the present disclosure does not exclude a structure having three single-adjustable dampers that can rotate one damper, and therefore, the cold air supply adjustment unit 300 may also be configured as a structure having three single-adjustable dampers that can rotate one damper.

[0114] In addition, according to the cold air supply adjustment unit 300, the opening area of ​​the large opening 313 is the largest among the plurality of openings 313, 314, and 322. The opening area of ​​the small opening 322 is the smallest among the plurality of openings 313, 314, and 322. The opening area of ​​the middle opening 314 is smaller than the opening area of ​​the large opening 313 and larger than the opening area of ​​the small opening 322.

[0115] In addition, according to the cold air supply adjustment unit 300, the following structure is formed: the large opening 313 is arranged in the center of the left and right direction. When viewed from the front side of the refrigerator 10, the middle opening 314 is arranged on the right side of the large opening 313, and the small opening 322 is arranged on the left side of the large opening 313.

[0116] However, the configuration of the plurality of openings 313 , 314 , and 322 is not limited thereto, and for example, may be configured as follows: when viewed from the front side of the refrigerator 10 , a small opening 322 is disposed on the right side of the large opening 313 , and a middle opening 314 is disposed on the left side of the large opening 313 .
