[0006] In the refrigerator of the conventional structure as described above, the fresh-keeping room is formed to be long in the horizontal direction in response to the desire to store long stored items or large stored items, and accordingly, the fresh-keeping room door for opening and closing the front surface opening of the fresh-keeping room is also formed to be long in the horizontal direction. Therefore, when the front surface opening of the refrigerating room is closed by the refrigerating room door, there are two refrigerating room doors in front of the fresh-keeping room door. Therefore, if the user does not open the two refrigerating room doors, that is, if the entire front surface opening of the refrigerating room is not opened, the fresh-keeping room door cannot be opened to allow stored items to enter or exit the fresh-keeping room.

[0007] The present embodiment provides the following technical solution: Regarding a refrigerator in which a second storage chamber such as a fresh food chamber is provided in a first storage chamber such as a cold room, stored items can be moved in and out of the second storage chamber even when only at least a portion of the front surface opening of the first storage chamber is open.

[0008] The refrigerator involved in this embodiment comprises: a first storage chamber, which is cooled to a first temperature zone; a storage chamber door, which opens and closes the front surface opening of the first storage chamber; a second storage chamber, which is arranged in the first storage chamber and can be cooled to a second temperature zone different from the first temperature zone; and a cold air supply unit, which can supply cold air into the second storage chamber and from the front side to the rear side, and when the storage chamber door opens at least a part of the front surface opening of the first storage chamber, at least a part of the front surface opening of the second storage chamber is opened to the front side.

[0009] According to the above configuration, even in a state where at least a portion of the front opening of the first storage chamber is open, stored objects can be taken in and out of the second storage chamber. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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.

[0033] In this case, storage chamber 12 is a cold storage chamber maintained within a temperature range of a refrigerating temperature zone. Hereinafter, storage chamber 12 is sometimes referred to as "cold storage chamber 12". The refrigerating temperature zone is an example of a first temperature zone, and cold storage chamber 12 is an example of a first storage chamber. In this case, storage chamber 13 is a vegetable chamber maintained within a temperature range of a refrigerating temperature zone. Hereinafter, storage chamber 13 is sometimes referred to as "vegetable chamber 13". In this case, storage chamber 14 is an ice-making chamber maintained within a temperature range of a freezing temperature zone. Hereinafter, storage chamber 14 is sometimes referred to as "ice-making chamber 14". In this case, storage chamber 15 is a small freezing chamber maintained within a temperature range of a freezing temperature zone. Hereinafter, storage chamber 15 is sometimes referred to as "small freezing chamber 15". In this case, storage chamber 16 is a large freezing chamber maintained within a temperature range of a freezing temperature zone. Hereinafter, storage chamber 16 is sometimes referred to as "large freezing chamber 16".

[0034] 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 center of the up-down 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.

[0035] 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.

[0036] 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.

[0037] 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].

[0038] 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.

[0039] Also like Figure 2 As shown in the example, a fresh-keeping room 20 is provided in the refrigerating room 12. In this case, the fresh-keeping room 20 is provided in the lower part of the refrigerating room 12. The fresh-keeping room 20 is an example of a second storage room provided in the first storage room. The fresh-keeping room 20 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 20 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 second temperature zone. In this case, the fresh-keeping temperature zone is assumed to be a temperature zone lower than the refrigerating temperature zone.

[0040] The fresh food compartment 20 contains a plurality of containers capable of storing stored goods. In this case, three containers, namely, a large container 21, a medium container 22, and a small container 23, are stored in a manner that can be pulled out in the front-rear direction. The large container 21, the medium container 22, and the small container 23 that are pulled out in the fresh food compartment 20 allow the user to pull the large container 21, the medium container 22, and the small container 23 forward, thereby allowing the stored goods to enter and exit the large container 21, the medium container 22, and the small container 23.

[0041] In this case, the large container 21 is arranged in the upper region R1 in the fresh food compartment 20. The upper region R1 is an example of the first cooling region. The middle container 22 and the small container 23 are arranged in the lower region R2 in the fresh food compartment 20. The lower region R2 is an example of the second cooling region. The middle container 22 and the small container 23 are arranged in the left-right direction below the large container 21. In this case, when viewed from the front side of the refrigerator 10, the middle container 22 is arranged on the right side of the lower region R2 in the fresh food compartment 20, and the small container 23 is arranged on the left side of the lower region R2 in the fresh food compartment 20. In addition, the following structure can also be formed: when viewed from the front side of the refrigerator 10, the middle container 22 is arranged on the left side of the lower region R2 in the fresh food compartment 20, and the small container 23 is arranged on the right side of the lower region R2 in the fresh food compartment 20.

[0042] In the lower region R2 in the cold and fresh room 20, a water supply box 24 is accommodated in a position further to the left than the small container 23 so as to be pulled out in the front-back direction. The water supply box 24 is a box that can store water for ice making. Although the detailed illustration is omitted, the water stored in the water supply box 24 is supplied to the ice maker in the ice making room 14 via a water supply pipe by a pump.

[0043] The large container 21 is an example of a first container, and in this case, is formed into a shallow rectangular box shape with an open upper surface. Although the front surface of the large container 21 is provided with a handle portion 21a for the user to hang his fingers, the large container 21 is formed so that the front surface opening of the upper layer region R1 is substantially open when the large container 21 is accommodated in the upper layer region R1 of the cold fresh compartment 20. Therefore, even if the user does not pull the large container 21 out of the cold fresh compartment 20, the stored items can be put in and out of the large container 21 to some extent.

[0044] The middle container 22 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 22 is wall-shaped, and is formed into a structure in which the front surface opening of the lower layer area R2 is substantially closed when the middle container 22 is accommodated in the lower layer area R2 in the cold fresh room 20.

[0045] The small container 23 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 small container 23 is also wall-shaped, and is formed into a structure in which the front surface opening of the lower layer area R2 is substantially closed when the small container 23 is accommodated in the lower layer area R2 in the cold fresh room 20.

[0046] The sizes of the storage spaces for storing the stored items of the large container 21, the medium container 22, and the small container 23 are different. In this case, the size of the storage space of the large container 21 is the largest among the multiple containers 21, 22, and 23. The size of the storage space of the small container 23 is the smallest among the multiple containers 21, 22, and 23. The size of the storage space of the medium container 22 is smaller than the storage space of the large container 21, and larger than the storage space of the small container 23.

[0047] A plate-shaped partition member 30 is provided above the large container 21. The fresh food compartment 20 is formed by a space below the partition member 30. The partition member 30 partitions the space between the partition member 30 and the large container 21 from the refrigerating compartment 12 as a part of the fresh food compartment 20.

[0048] 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 30 is provided as a structural element different from the above-mentioned shelf members 12T. However, the partition member 30 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 30.

[0049] The upper region R1 in the fresh-keeping room 20 is structured as follows: there is no fresh-keeping room door that makes the fresh-keeping room 20 roughly a closed space. That is, the upper region R1 in the fresh-keeping room 20 is formed as an open space whose front surface opening is always open. Therefore, the refrigerator 10 is structured 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 21 and the partition member 30 is open to the front side. In addition, the refrigerator 10 is structured 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 21 and the partition member 30, that is, the portion opposite to the open refrigerator door, is open to the front side.

[0050] In addition, the lower region R2 in the fresh-keeping room 20 is also structured as follows: there is no fresh-keeping room door that makes the fresh-keeping room 20 substantially a closed space. However, it is structured as follows: the front surface of the middle container 22 and the front surface of the small container 23 accommodated in the lower region R2 in the fresh-keeping room 20 can function as a fresh-keeping room cover that closes the lower region R2 in the fresh-keeping room 20.

[0051] like Figure 3 For example, when the left door 12D[L] of the refrigerator compartment closes the front opening of the refrigerator compartment 12, and the right door 12D[R] of the refrigerator compartment opens the front opening of the refrigerator compartment 12 by, for example, 90 degrees or more, Figure 4 As shown in the example, the small container 23 cannot be pulled out forward, but the medium container 22 can be pulled out forward.

[0052] like Figure 5 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, for example, 90 degrees or more, Figure 6 As shown in the example, the middle container 22 cannot be pulled out forward, but the small container 23 can be pulled out forward.

[0053] like Figure 7As shown in the example, the refrigerator 10 is provided with a cooler chamber 40. In this case, the cooler chamber 40 is provided at the rear side of the vegetable chamber 13. A cooler or an air supply fan, etc., not shown in the figure, is accommodated in the cooler chamber 40. The cooler and a compressor, etc., not shown in the figure, together constitute a well-known refrigeration cycle mechanism, generating cold air for cooling the inside of the refrigerating chamber 12 and the vegetable chamber 13. The air supply fan delivers the cold air generated by the cooler into the refrigerating chamber 12 and even into the vegetable chamber 13.

[0054] In the upper part of the cooler room 40, a refrigerator duct 41 is provided extending upward along the rear surface of the refrigerator room 12. A plurality of cold air outlets 42 for the refrigerator room are provided in the refrigerator duct 41. In addition, as a cold air outlet for the fresh air room, a plurality of cold air outlets are provided in the refrigerator duct 41, in which a large container cold air outlet 43, a medium container cold air outlet 44, and a small container cold air outlet 45 are provided.

[0055] The cold air generated by the cooler passes through the refrigerator duct 41 due to the blowing action of the blower fan, and is supplied from the cold air outlet 42 for the refrigerating chamber into the refrigerating chamber 12. Thus, the inside of the refrigerating chamber 12 is cooled to a temperature within a predetermined refrigerating temperature range.

[0056] In addition, the cold air generated by the cooler passes through the refrigerator duct 41 due to the air supply effect of the air supply fan, and is supplied from the large container cold air outlet 43 to the large container 21 in the fresh-keeping room 20. As a result, the inside of the large container 21 is cooled to a temperature range within a predetermined fresh-keeping temperature zone. The large container cold air outlet 43 is an example of a first opening that allows cold air to flow into the upper region R1 of the fresh-keeping room 20.

[0057] In addition, the cold air generated by the cooler passes through the refrigerator duct 41 due to the air supply effect of the air supply fan, and is supplied from the middle container cold air outlet 44 to the middle container 22 in the fresh-keeping room 20. As a result, the inside of the middle container 22 is cooled to a temperature within the prescribed fresh-keeping temperature range. The middle container cold air outlet 44 is an example of a second opening that allows cold air to flow into the lower layer area R2 of the fresh-keeping room 20.

[0058] In addition, the cold air generated by the cooler passes through the refrigerator duct 41 due to the air supply effect of the air supply fan, and is supplied from the small container cold air outlet 45 to the small container 23 in the cold fresh room 20. As a result, the inside of the small container 23 is cooled to a temperature within the prescribed cold fresh temperature range. The small container cold air outlet 45 is an example of a second opening that allows the cold air to flow into the lower layer area R2 of the cold fresh room 20.

[0059] like Figure 8As shown in the example, a cold air diverter 50 capable of adjusting the amount of cold air supplied to the refrigerator compartment 12, the large container 21, the medium container 22, and the small container 23 is provided in the refrigerator internal duct 41. The cold air diverter 50 is an example of a diverter that diverts the cold air generated by the cooler to the cold air outlet 42 side for the refrigerator compartment, the cold air outlet 43 side for the large container, the cold air outlet 44 side for the medium container, and the cold air outlet 45 side for the small container. In this case, a double damper 51 and a single damper 52 are provided.

[0060] The double damper 51 is formed into a structure including a large damper 51a and a medium damper 51b. The double damper 51 includes a large opening (not shown) that is opened and closed by the large damper 51a. In addition, the double damper 51 includes a medium opening (not shown) that is opened and closed by the medium damper 51b. The large opening is located below the large container cold air outlet 43. The medium opening is located below the medium container cold air outlet 44.

[0061] The large damper 51a and the medium damper 51b are configured to be rotatable by a common motor (not shown) provided in the double damper 51. That is, the double damper 51 is configured to be able to rotate a plurality of dampers, in this case two dampers, by a single motor.

[0062] The double damper 51 can adjust the transmission mechanism (not shown) that transmits the rotational force of the motor to the large damper 51a and the medium damper 51b, so that the opening degrees of the large damper 51a and the medium damper 51b are different or the same.

[0063] The large air door 51a is an example of a switching component, and the double adjustment air door 51 controls the driving of the motor not shown in the figure to switch the large air door 51a 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 is blocked from flowing to the cold air outlet 43 for the large container. That is, the blocking state is a state in which the large air door 51a closes the large opening. 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 is allowed to flow to the cold air outlet 43 for the large container. That is, the allowing state is a state in which the large air door 51a opens the large opening.

[0064] The middle air door 51b is an example of a switching component, and the double adjustment air door 51 controls the driving of the motor not shown in the figure to switch the middle air door 51b 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 is blocked from flowing to the cold air outlet 44 for the middle container. That is, the blocking state is a state in which the middle air door 51b closes the middle opening. 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 is allowed to flow to the cold air outlet 44 for the middle container. That is, the allowing state is a state in which the middle air door 51b opens the middle opening.

[0065] The single damper 52 is formed as a structure including one small damper (not shown). The single damper 52 includes a small opening (not shown) opened and closed by the small damper. The small opening is located below the small container cold air outlet 45.

[0066] The small damper is configured to be rotatable by a single motor (not shown) provided in the single damper 52. That is, the single damper 52 is configured to be rotatable by a single motor.

[0067] The small air door is an example of a switching component, and the small air door can be switched between a blocking state and a allowing state by controlling the driving of the motor (not shown) by adjusting the air door 52 alone. The blocking state is an example of a first state, and is a state in which the cold air generated by the cooler is blocked from flowing to the cold air outlet 45 for the small container. That is, the blocking state is a state in which the small air door closes the small opening. 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 is allowed to flow to the cold air outlet 45 for the small container. That is, the allowing state is a state in which the small air door opens the small opening.

[0068] According to the refrigerator 10, the opening of the plurality of dampers can be appropriately changed to adjust the amount and intensity of cold air supplied to the large container 21, the middle container 22, and the small container 23. Thus, the cooling capacity of the large container 21, the middle container 22, and the small container 23 can be adjusted respectively. That is, according to the refrigerator 10, the upper region R1 and the lower region R2 can be cooled to different temperature zones. In addition, according to the refrigerator 10, the large container 21, the middle container 22, and the small container 23 can be cooled by different cooling modes.

[0069] like Fig. 9 As shown in the example, the refrigerator 10 includes a cold air supply unit 100 for supplying cold air mainly to the upper region R1 in the fresh air compartment 20. Next, a configuration example of the cold air supply unit 100 will be described in detail. The cold air supply unit 100 includes a rectifying unit 101 and a returning unit 102.

[0070] The rectifying section 101 is an example of the first guide section. In this case, the rectifying section 101 is formed by the lower surface of the partition member 30, and thus is formed into a planar structure extending in the front-rear direction. The rear end of the rectifying section 101 is connected to the large container cold air outlet 43. Fig. 9 As shown by arrow A1 in the figure, the rectifying unit 101 guides the cold air blown out from the large container cold air outlet 43 toward the front side from the rear side to the front side along the lower surface of the rectifying unit 101. That is, the rectifying unit 101 rectify the cold air blown out from the large container cold air outlet 43 so that it flows toward the front side.

[0071] The return portion 102 is an example of a second guide portion. The return portion 102 is provided at the front end of the rectifying portion 101 so as to be smoothly folded back from the upper front side toward the lower rear side. Fig. 9 As shown by arrow A2 in the figure, the return part 102 guides the cold air guided from the rear side to the front side by the rectifying part 101 from the front side to the rear side, and more specifically, guides the cold air from the upper front side to the lower rear side. That is, the return part 102 allows the cold air transported from the rectifying part 101 to the front side to return in a manner toward the rear side.

[0072] According to the first embodiment shown by way of example above, in the refrigerator 10, a fresh-keeping room 20 is provided as a special storage room in the refrigerator room 12, and the front surface opening of the refrigerator room 12 is opened and closed by the refrigerator room right door 12D[R] and the refrigerator room left door 12D[L], and the fresh-keeping room 20 is not provided with a structure of a fresh-keeping room door that makes the fresh-keeping room 20 substantially a closed space. According to this structural example, even when at least a portion of the front surface opening of the refrigerator room 12 is open, stored goods can be put in and out of the fresh-keeping room 20.

[0073] 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 21 corresponding to the right door 12D[R] of the refrigerator, and can also move stored items in and out of the middle container 22.

[0074] 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 21 corresponding to the left door 12D[L] of the refrigerator, and can also move stored items in and out of the small container 23.

[0075] In addition, the cold air supply unit 100 conveys the cold air blown out from the large container cold air outlet 43 toward the front side as it is, along the rectifying unit 101 from the rear side to the front side, and then guides the cold air from the rear side toward the front side by using the return unit 102, and more specifically, guides the cold air from the upper front side toward the lower rear side. According to this structural example, even if the cold fresh room 20 does not have a cold fresh room door, the cold air sent from the return unit 102 toward the lower rear side can form a wall, a so-called cold air curtain, on the front surface of the cold fresh room 20, thereby preventing the cold air from leaking out of the cold fresh room 20. In this way, insufficient cooling in the cold fresh room 20 can be prevented.

[0076] In addition, the return portion 102 is configured to return from the front end portion of the partition member 30 to the rear side. According to this structural example, when observing from the front side or the upper side of the front of the refrigerator 10, it is possible to avoid the return portion 102 blocking the fresh-keeping room 20, and it is possible to suppress the situation in which the visual confirmation of the fresh-keeping room 20 is reduced due to the return portion 102.

[0077] (Second Embodiment)

[0078] Fig.10 The cold air supply unit 200 shown in the example is provided with a cold air flow path 201 in the cold fresh room 20. In this case, the cold air flow path 201 is provided along the bottom of the large container 21. A cold air inlet 202 for allowing cold air to enter the cold air flow path 201 is provided at the rear end of the cold air flow path 201. The cold air flow path 201 is located in the upper region R1 in the cold fresh room 20, in front of the cold air outlet 43 for the large container, and when viewed from the front side of the refrigerator 10, the cold air outlet 43 for the large container overlaps with the cold air inlet 202 in the front-to-back direction. In addition, the central part of the cold air outlet 43 for the large container in the vertical direction and the central part of the cold air inlet 202 in the vertical direction are at approximately or completely the same height position.

[0079] According to this structural example, if the large container 21 is accommodated in the upper region R1 in the fresh air compartment 20, the cold air inlet 202 of the cold air flow path 201 is connected to the large container cold air outlet 43. In addition, the large container cold air outlet 43 and the cold air inlet 202 are provided at the lower side of the upper region R1 in the fresh air compartment 20, that is, the side close to the cold air diverter 50.

[0080] A cold air outlet 203 is provided at the front end of the cold air flow path 201. The cold air outlet 203 is opened upward at the front end of the cold air flow path 201, and blows the cold air entering the cold air flow path 201 from the large container cold air outlet 43 upward. In this structural example, the cold air flow path 201 functions as an example of a cold air guide air path that guides cold air from the large container cold air outlet 43 toward the cold air outlet 203. In this case, the cold air outlet 203 is formed as an opening that extends vertically in the up-down direction.

[0081] The height of the partition member 30 can be selectively installed at least at a first position and a second position having a height different from the first position above the large container 21. In more detail, the end of the partition member 30 in the left and right direction can be selectively placed on: either a first protrusion 30a or a second protrusion 30b provided on the inner side surface of the refrigerating chamber 12.

[0082] Furthermore, the first protrusion 30a and the second protrusion 30b are formed in multiple layers at predetermined intervals in the vertical direction, in this case, in two layers. That is, if the height position at which the first protrusion 30a is provided is defined as the first position, the second protrusion 30b is formed at a height position different from the first position, in this case, at a position higher than the first position, that is, the second position.

[0083] The partition member 30 can be selectively mounted at any height position of the first protrusion 30 a and the second protrusion 30 b . Therefore, the user can appropriately adjust the height of the partition member 30 above the large container 21 .

[0084] In addition, the first protrusion 30a and the second protrusion 30b may be, for example, rib-shaped protrusions integrally provided on the inner box forming the inner surface of the heat-insulating box body 11, or may be fixtures installed on the inner box, etc. In addition, the number of layers of the protrusion is not limited to 2 layers, and may be, for example, multiple layers of 3 or more layers.

[0085] In the conventional refrigerator, the fresh food compartment door is rotatably mounted on the front end of the member corresponding to the partition member 30, and therefore, it is difficult to configure such that the height of the member corresponding to the partition member 30 can be changed. According to the refrigerator 10 involved in the present disclosure, the fresh food compartment door is not provided on the partition member 30, and therefore, as described above, a structure capable of reasonably changing the height of the partition member 30 can be realized.

[0086] like Fig.11For example, a resin plate 60 and a metal plate 61 that can be separated from the large container 21 can be arranged in the large container 21. The resin plate 60 and the metal plate 61 can both be defined as bottom plates that can form the bottom surface of the large container 21. The resin plate 60 is formed of, for example, a plastic material. The metal plate 61 is formed of, for example, a metal material such as aluminum.

[0087] When the resin plate 60 is disposed in the large container 21 and the metal plate 61 is not disposed, the upper surface of the resin plate 60 functions as a placement surface on which stored items can be placed in the large container 21. That is, the resin plate 60 can be defined as an example of a placement member that can form a placement surface.

[0088] In addition, if Fig.12 As shown in the example, when the resin plate 60 is arranged in the large container 21 and the metal plate 61 is arranged on the resin plate 60, the upper surface of the metal plate 61 functions as a loading surface on which the stored items can be loaded in the large container 21. That is, the metal plate 61 can be defined as an example of a metal member that can form a loading surface.

[0089] The cold air flow path 201 is formed between the bottom surface in the large container 21 and the resin plate 60 disposed in the large container 21, or between the bottom surface in the large container 21 and the metal plate 61 disposed in the large container 21. More specifically, the cold air flow path 201 is formed between the bottom surface in the large container 21 and the placement surface formed by the resin plate 60 disposed in the large container 21, or between the bottom surface in the large container 21 and the placement surface formed by the metal plate 61 disposed in the large container 21.

[0090] like Fig.11 As shown in the example, the resin plate 60 has a plurality of cold air supply holes 60a penetrating the resin plate 60. The cold air supply holes 60a can supply cold air from the cold air flow path 201 toward the metal plate 61. On the other hand, the metal plate 61 is a non-porous plate having no cold air supply holes penetrating the metal plate 61.

[0091] The metal plate 61 is cooled not only by the cold air in the fresh air compartment 20, but also by the cold air supplied from the cold air flow path 201 through the cold air supply hole 60a. Thus, the cooling of the stored items placed on the metal plate 61 can be promoted. That is, the metal plate 61 functions as an example of a heat exchange promotion unit that promotes heat exchange between the cold air in the cold air flow path 201 and the stored items in the fresh air compartment 20.

[0092] like Fig.11As shown in the example, a plurality of front ribs 60b protruding into the cold air outlet 203 are provided on the front surface of the front end portion of the resin plate 60. The front rib 60b is an example of a protruding portion in the cold air outlet, and prevents the front surface of the front end portion of the resin plate 60 from contacting the rear surface of the front end portion of the large container 21, that is, prevents the cold air outlet 203 from not being formed.

[0093] Furthermore, the front rib 60b may be provided on the rear surface of the front end portion of the large container 21 instead of the front surface of the front end portion of the resin plate 60, or may be provided on both the front surface of the front end portion of the resin plate 60 and the rear surface of the front end portion of the large container 21. In other words, the front rib 60b may be provided on at least one of the front surface of the front end portion of the resin plate 60 and the rear surface of the front end portion of the large container 21.

[0094] In addition, if Fig.13 As shown in the example, a plurality of bottom ribs 60c, 60d, 60e, and 60f are provided on the lower surface of the resin plate 60, protruding into the cold air flow path 201. The bottom ribs 60c, 60d, 60e, and 60f are an example of protruding portions in the cold air guide air path, and prevent the lower surface of the resin plate 60 from contacting the bottom surface of the large container 21, that is, prevent the cold air flow path 201 from being formed.

[0095] Furthermore, the bottom ribs 60c, 60d, 60e, and 60f may be provided on the bottom surface of the large container 21 instead of the lower surface of the resin plate 60, or may be provided on both the lower surface of the resin plate 60 and the bottom surface of the large container 21. In other words, the bottom ribs 60c, 60d, 60e, and 60f may be provided on at least one of the bottom surface of the large container 21 and the lower surface of the resin plate 60.

[0096] The bottom ribs 60c and 60d are provided on one side in the width direction of the resin plate 60, and in this case, are provided on the right side of the center portion in the width direction. Hereinafter, the bottom ribs 60c and 60d are sometimes referred to as right side protrusions 60c and 60d. The bottom ribs 60e and 60f are provided on the other side in the width direction of the resin plate 60, and in this case, are provided on the left side of the center portion in the width direction. Hereinafter, the bottom ribs 60e and 60f are sometimes referred to as left side protrusions 60e and 60f.

[0097] The central protrusion 60c provided on the central side in the width direction of the resin plate 60 among the plurality of right protrusions 60c and 60d extends linearly in the front-rear direction. In addition, the right end protrusion 60d provided on the right end side in the width direction of the resin plate 60 among the plurality of right protrusions 60c and 60d extends in a manner inclined from the rear toward the front and toward the right.

[0098] The central protrusion 60e provided on the central side in the width direction of the resin plate 60 among the plurality of left protrusions 60e and 60f extends linearly in the front-rear direction. In addition, the left end protrusion 60f provided on the left end side in the width direction of the resin plate 60 among the plurality of left protrusions 60e and 60f extends in a manner inclined from the rear toward the front and toward the left.

[0099] The resin plate 60 has an enlarged region R3 that enlarges the interval between the right end protrusion 60d and the left end protrusion 60f from the cold air inlet 202 toward the cold air outlet 203. In this case, the interval between the right end protrusion 60d and the left end protrusion 60f gradually enlarges from the cold air inlet 202 toward the cold air outlet 203, and thus the enlarged region R3 is formed as an area covering the entire range from the rear end to the front end of the right end protrusion 60d and the left end protrusion 60f. In addition, the interval between the central protrusion 60c and the central protrusion 60e is constant throughout the entire range from the rear end to the front end of the central protrusion 60c and the central protrusion 60e.

[0100] The cold air entering the cold air flow path 201 from the large container cold air outlet 43 passes through between the central protrusion 60c and the central protrusion 60e, between the central protrusion 60c and the right end protrusion 60d, and between the central protrusion 60e and the left end protrusion 60f, and is sent out from the cold air delivery outlet 203. That is, the plurality of bottom ribs 60c, 60d, 60e, and 60f function as guide plates that guide the cold air flowing in the cold air flow path 201 toward the cold air delivery outlet 203.

[0101] According to the second embodiment shown in the above example, the cold air supply unit 200 includes: a cold air flow path 201 for the flow of cold air blown out from the cold air outlet 43 for the large container. In addition, the cold air supply unit 200 includes: a metal plate 61 for promoting heat exchange between the cold air in the cold air flow path 201 and the stored items in the cold fresh room 20. According to this structural example, regarding the structure in which the cold fresh room 20 does not have a cold fresh room door, even if the cooling in the cold fresh room is insufficient, the cold source heat of the cold air in the cold air flow path 201 can be transferred to the stored items by means of the metal plate 61, thereby suppressing insufficient cooling of the stored items.

[0102] In addition, according to the cold air supply unit 200, a cold air outlet 203 capable of sending cold air upward is provided at the bottom of the fresh air room 20. According to this structural example, even if the fresh air room 20 does not have a fresh air room door, the cold air sent upward from the cold air outlet 203 can form a wall, a so-called cold air curtain, on the front surface of the fresh air room 20, so that the cold air curtain can be used to suppress the leakage of cold air from the fresh air room 20. In this way, insufficient cooling in the fresh air room 20 can be suppressed.

[0103] In addition, the cold air flow path 201 is provided between the bottom surface of the large container 21 and the loading surface on which the stored items can be loaded in the cold freshness chamber 20. According to this structural example, since the cold air flow path 201 exists between the loading surface on which the stored items are loaded and the bottom surface of the large container 21, the cold source heat of the cold air in the cold air flow path 201 can be easily transferred to the stored items, thereby cooling the stored items more efficiently.

[0104] In addition, according to the cold air supply unit 200, the large container cold air outlet 43 and the cold air inlet 202 overlap in the front-to-back direction when viewed from the front side of the refrigerator 10. According to this structural example, as the large container 21 is accommodated in the upper region R1 in the cold fresh room 20, the cold air inlet 202 of the cold air flow path 201 can be connected to the large container cold air outlet 43, and a cold air supply path to the cold air flow path 201 can be easily and automatically formed. In addition, by removing the large container 21 from the upper region R1 in the cold fresh room 20, the large container cold air outlet 43 can be exposed, so that the large container cold air outlet 43 and its surrounding parts can be easily cleaned and maintained.

[0105] In addition, the cold air supply unit 200 may be formed as follows: an airtight component such as a gasket is provided between the cold air inlet 202 of the cold air flow path 201 and the large container cold air outlet 43, thereby airtightly connecting the cold air flow path 201 and the large container cold air outlet 43. The airtight component may be pre-installed at the rear end of the cold air flow path 201, or pre-installed at the front end of the large container cold air outlet 43, or may be sandwiched between the rear end of the cold air flow path 201 and the front end of the large container cold air outlet 43 when the large container 21 is accommodated in the cold fresh room 20.

[0106] In addition, according to the cold air supply unit 200, the large container cold air outlet 43 and the cold air inlet 202 are provided on the side close to the cold air diverter 50 in the upper region R1 of the fresh air chamber 20. According to this structural example, the portion for allowing cold air to enter the cold air flow path 201 from the large container cold air outlet 43 can be arranged at a position as close to the cold air diverter 50 as possible. Thus, the cold air can be supplied from the large container cold air outlet 43 to the cold air flow path 201 while maintaining the momentum of the cold air as much as possible, so that the cold air can be blown out from the cold air delivery outlet 203 with good momentum to form a strong cold air curtain.

[0107] Furthermore, according to the cold air supply unit 200, the cold air flow path 201 through which the cold air flows is formed in the large container 21. According to this configuration example, the cold air flowing in the cold air flow path 201 can efficiently cool the large container 21 itself.

[0108] In addition, a plurality of front ribs 60b protruding into the cold air outlet 203 are provided on the front surface of the front end portion of the resin plate 60. According to this configuration example, the cold air outlet 203 having a sufficient size to smoothly send cold air can be reliably formed.

[0109] In addition, a plurality of bottom ribs 60c, 60d, 60e, and 60f are formed on the lower surface of the resin plate 60, protruding into the cold air flow path 201. According to this structural example, a cold air flow path 201 having a sufficient size to allow the cold air to flow smoothly can be reliably formed. In addition, since the bottom ribs 60c, 60d, 60e, and 60f function as guide plates, the cold air flowing in the cold air flow path 201 can be smoothly guided to the cold air delivery port 203.

[0110] In addition, the resin plate 60 has an expansion area R3 that expands the interval between the right end protrusion 60d and the left end protrusion 60f from the cold air inlet 202 toward the cold air outlet 203. According to this structural example, cold air can be supplied to a wide range as wide as possible from the cold air inlet 202 toward the cold air outlet 203, so that a cold air curtain can be formed over a wide range in the front surface opening of the cold fresh room 20.

[0111] Furthermore, the resin plate 60 can be supported from below by the plurality of bottom ribs 60 c , 60 d , 60 e , and 60 f , so that deformation of the resin plate 60 and, by extension, deformation of the cold air flow path 201 can be suppressed.

[0112] In addition, the resin plate 60 has a cold air supply hole 60a that can supply cold air from the cold air flow path 201 toward the metal plate 61. According to this structural example, the metal plate 61 can be efficiently cooled by the cold air passing through the cold air supply hole 60a from the cold air flow path 201, and the stored items placed on the metal plate 61 can be cooled more efficiently.

[0113] In addition, the cold air supply holes 60a are dispersedly arranged throughout the resin plate 60. Thus, the entire metal plate 61 can be cooled uniformly, and the state of different cooling intensities in different places, so-called uneven cooling, can be avoided. In addition, the entire metal plate 61 can be cooled quickly, and the stored items on the metal plate 61 can be cooled quickly.

[0114] In addition, the resin plate 60 or the metal plate 61 can be attached to and detached from the large container 21. According to this structural example, by removing the resin plate 60 or the metal plate 61 from the large container 21, maintenance such as cleaning of the large container 21, the resin plate 60, and the metal plate 61 can be easily performed. In addition, by appropriately performing maintenance such as cleaning of the large container 21, the resin plate 60, and the metal plate 61, it is possible to avoid the state where foreign matter exists in the cold air flow path 201, and the cold air flow in the cold air flow path 201 can be well maintained.

[0115] In addition, the resin plate 60 may be formed into a non-porous structure without the cold air supply hole 60a. According to this structural example, the cold source heat in the cold air flow path 201 can be transferred to the metal plate 61 by means of the resin plate 60, so that the metal plate 61 and even the storage items on the metal plate 61 can be cooled.

[0116] Alternatively, the metal plate 61 may be directly disposed in the large container 21 without disposing the resin plate 60. In this case, a cold air flow path can be formed between the bottom surface of the large container 21 and the lower surface of the metal plate 61.

[0117] In addition, the large container 21 can also be used in a state where the resin plate 60 or the metal plate 61 is not arranged in the large container 21. In this case, the cold air delivery port 203 is not formed, so the function of suppressing the leakage of cold air by the cold air curtain is limited, but the capacity in the large container 21 can be increased compared to the case where the resin plate 60 or the metal plate 61 is arranged in the large container 21.

[0118] In addition, the resin plate 60 and the metal plate 61 may be structured as follows: divided into a plurality of parts in the left-right direction. According to this structural example, the resin plate 60 or the metal plate 61 is arranged in a part of the large container 21 to form a cold air curtain in the part, and the capacity can be increased in other parts.

[0119] In addition, if Fig.14 As shown in the example, the cold air delivery port 203 can be tilted in a manner pointing forward. In addition, although not shown in the figure, the cold air delivery port 203 can also be tilted in a manner pointing backward, or can be tilted in a manner pointing to the left or right, etc. In addition, it can be formed as a structure in which the bottom surface of the large container 21 is provided with a cold air supply hole 21b. According to this structural example, the cold air flowing in the cold air flow path 201 can also be supplied to the lower layer area R2, thereby suppressing: insufficient cooling of the lower layer area R2 without the cold fresh room door.

[0120] (Third Embodiment)

[0121] like Fig.15 For example, when the front 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 portion closed by the longitudinal partition plate 12S has lower thermal insulation performance than the portion closed by the refrigerator compartment right door 12D[R] and the refrigerator compartment left door 12D[L]. Therefore, if the back of the refrigerator compartment right door 12D[R] and the refrigerator compartment left door 12D[L] is defined as a first thermal insulation area having a thermal insulation performance of a predetermined reference, the back of the longitudinal partition plate 12S can be defined as a second thermal insulation area having a lower thermal insulation performance than the first thermal insulation area.

[0122] Furthermore, in the third embodiment, the cold air supply unit 300 is configured to suppress the supply of cold air to the back side of the longitudinal partition plate 12S more than the supply of cold air to the back side of the refrigerating chamber right door 12D[R] and the refrigerating chamber left door 12D[L]. More specifically, the cold air supply unit 300 includes a cold air delivery port 203 behind the back side of the refrigerating chamber right door 12D[R] and the refrigerating chamber left door 12D[L], and does not include a cold air delivery port 203 behind the back side of the longitudinal partition plate 12S.

[0123] The cold air supply unit 300 configured in this way supplies cold air from a portion facing the back of the right door 12D[R] and the left door 12D[L] of the refrigerating chamber, rather than the portion facing the back of the longitudinal partition plate 12S. Therefore, even if the cold air delivered from the cold air delivery port 203 leaks from the front surface opening of the fresh-keeping chamber 20, the cold air is likely to flow toward the right door 12D[R] and the left door 12D[L] of the refrigerating chamber, but is unlikely to flow toward the longitudinal partition plate 12S. Therefore, compared with the supply of cold air to the back of the right door 12D[R] and the left door 12D[L] of the refrigerating chamber, the supply of cold air to the back of the longitudinal partition plate 12S can be further suppressed.

[0124] In addition, the cold air supply unit 300 is provided with a bottom rib 302 and an inclined portion 303 in the cold air flow path 301. The bottom rib 302 is arranged to extend in a straight line in the front-to-back direction behind the back surface of the longitudinal partition plate 12S. The inclined portion 303 is formed at the front end portion of the bottom rib 302 as an inclined surface that gradually expands from the rear of the central portion in the left-right direction of the longitudinal partition plate 12S toward the left and right ends. The inclined portion 303 guides the cold air flowing in the cold air flow path 301 from the longitudinal partition plate 12S side toward the right door 12D[R] side of the refrigerating chamber and the left door 12D[L] side of the refrigerating chamber. Thus, the cold air supply unit 300 adjusts the cold air flow in the cold air flow path 201 to be from the longitudinal partition plate 12S side toward the right door 12D[R] side of the refrigerating chamber and the left door 12D[L] side of the refrigerating chamber. Therefore, the supply of cold air to the back surface of the vertical partition plate 12S can be further suppressed compared to the supply of cold air to the back surface of the refrigerating chamber right door 12D[R] and the refrigerating chamber left door 12D[L].

[0125] According to the third embodiment, the cold air supply unit 300 further suppresses the supply of cold air to the back side of the vertical partition plate 12S, compared with the supply of cold air to the back side of the right door 12D[R] and the left door 12D[L] of the refrigerating chamber. As a result, it is difficult for cold air to flow toward the vertical partition plate 12S having lower heat insulation performance than the right door 12D[R] and the left door 12D[L] of the refrigerating chamber, and it is possible to suppress the leakage of cold source heat from the vertical partition plate 12S portion having lower heat insulation performance.

[0126] The cold air supply unit 300 supplies cold air from the portion opposite to the right door 12D[R] and the left door 12D[L] of the refrigerating chamber, which have a higher heat insulation performance than the longitudinal partition 12S. As a result, it is more difficult for cold air to flow toward the longitudinal partition 12S, which has a lower heat insulation performance than the right door 12D[R] and the left door 12D[L] of the refrigerating chamber, and the leakage of cold source heat from the longitudinal partition 12S portion with lower heat insulation performance can be further suppressed.

[0127] The cold air supply unit 300 adjusts the cold air flow in the cold air flow path 301 to flow from the longitudinal partition plate 12S side with lower heat insulation performance toward the right door 12D[R] side and the left door 12D[L] side of the refrigerating chamber with higher heat insulation performance by using the inclined portion 303. Thus, the cold air can be further prevented from flowing toward the longitudinal partition plate 12S with lower heat insulation performance, and the cold source heat can be further prevented from leaking from the longitudinal partition plate 12S with lower heat insulation performance.

[0128] Furthermore, when the front opening of the refrigerating chamber 12 is closed by the right refrigerating chamber door 12D[R] and the left refrigerating chamber door 12D[L], the door pocket 12P provided on the back of the right refrigerating chamber door 12D[R] and the back of the left refrigerating chamber door 12D[L] is arranged in front of the cold air delivery port 203. Therefore, the door pocket 12P can suppress the cold air from leaking out of the front opening of the cold fresh chamber 20.

[0129] And, if Fig.16 As shown in the example, when a portion of the door pocket 12P, in this case the right door 12D[R] and the left door 12D[L] of the refrigerator compartment close the front surface opening of the refrigerator compartment 12, the wall 12Pa disposed inside the refrigerator can be formed into a double structure, for example, to improve the heat insulation performance. According to this structural example, it is possible to suppress the situation where condensation is generated on the door pocket 12P due to the cold air that is trying to leak from the front surface opening of the fresh food compartment 20.

[0130] In addition, if Fig.17As shown in the example, a structure may be formed in which a cold air outlet 304 is provided, and the cold air outlet 304 is located above the two cold air outlets 203 provided behind the back of the right door 12D[R] and the left door 12D[L] of the refrigerating chamber, for example, to send cold air downward from the top surface of the fresh air chamber 20. According to this structural example, a cold air curtain can be formed by sending cold air from above using the cold air outlet 304 between the two cold air outlets 203 where cold air is not sent from below, that is, where it is difficult to form a cold air curtain. Thus, leakage of cold air from between the two cold air outlets 203 can be suppressed.

[0131] (Fourth Embodiment)

[0132] Fig.18 The refrigerator 10 shown in the example also has cold air outlets 400 at the upper portions of the left and right sides of the fresh air compartment 20. Fig.18 As shown by arrow A3 in the figure, cold air can also be supplied to the fresh room 20 from the side of the fresh room 20. According to this structural example, even if the fresh room 20 does not have a fresh room door, cold air can be supplied not only from the front surface of the fresh room 20 but also from the side surface, which can further suppress insufficient cooling in the fresh room 20.

[0133] (Other embodiments)

[0134] In addition, the present disclosure is not limited to the above-mentioned multiple embodiments, and various modifications and extensions can be made within the scope of the present disclosure. For example, the refrigerator 10 can be formed into an embodiment in which at least two or more of the above-mentioned multiple embodiments are appropriately selected and combined.

[0135] like Fig.19 As shown in the example, the refrigerator 10 can be formed into the following structure: a cold air duct 70 extending in the front-to-back direction is provided on the lower surface of the partition member 30. The rear end of the cold air duct 70 is connected to the cold air outlet 43 for large containers. In addition, a plurality of cold air delivery ports 71 are formed on the lower surface of the cold air duct 70. According to this structural example, cold air can also be efficiently supplied to the cold fresh room 20 without a cold fresh room door, and insufficient cooling in the cold fresh room 20 can be suppressed.

[0136] In addition, the cold air duct 70 may be formed as a structure having only the cold air delivery port 71 at the front end. According to this structural example, all the cold air supplied to the cold air duct 70 can be centrally delivered from the cold air delivery port 71 at the front end, and a strong cold air curtain can be formed at the front surface opening of the cold fresh room 20 without a cold fresh room door.

[0137] like Fig. 20For example, the following structure can be formed: a protruding member 80 is provided on the bottom surface of the large container 21 to form a cold air flow path 81. The protruding member 80 is integrally formed with: a right side wall 80a, which is arranged on the right side of the central part in the width direction of the large container 21; a left side wall 80b, which is arranged on the left side of the central part in the width direction of the large container 21; and an upper wall portion 80c, which connects the upper ends of the right side wall 80a and the left side wall 80b.

[0138] The right side wall 80a extends from the rear to the front and is inclined to the right. The left side wall 80b extends from the rear to the front and is inclined to the left. The upper wall portion 80c is formed into a substantially trapezoidal shape that gradually expands from the rear to the front. For example, a metal plate 61 can be placed on the upper surface of the protruding member 80.

[0139] A cold air flow path 81 surrounded by a right side wall 80a, a left side wall 80b, and an upper wall portion 80c is formed in the protruding member 80. A cold air inlet 80e is provided at the rear end of the cold air flow path 81. A cold air outlet 80f is provided at the front end of the cold air flow path 81. In this case, the cold air outlet 80f is formed as an opening pointing forward. The cold air sent out from the cold air outlet 80f contacts the rear surface of the front end of the large container 21 and faces upward.

[0140] In addition, the protruding member 80 may be configured by combining the right side wall 80a, the left side wall 80b, and the upper wall portion 80c which are formed of different members.

[0141] The refrigerator 10 may be configured as follows: a cooler for generating cold air is provided in a portion of the heat-insulating box body 11 that is located above the central portion in the vertical direction, for example, in the refrigerating chamber 12. The interior of the upper portion of the refrigerating chamber 12 is a portion that is easily a dead space that is difficult for a user's hand to reach. That is, the refrigerator 10 may be configured as follows: a cooler is provided in such a dead space.

[0142] The cold air flow divider 50 is formed into a structure in which, when viewed from the front side of the refrigerator 10, a double damper 51 is provided on the right side and a single damper 52 is provided on the left side. However, the cold air flow divider 50 may also be formed into a structure in which, when viewed from the front side of the refrigerator 10, a double damper 51 is provided on the left side and a single damper 52 is provided on the right side.

[0143] According to the cold air diversion part 50, it is formed as: a structure with a double adjustable damper 51 that can rotate two dampers. 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 diversion part 50 can be achieved.

[0144] In addition, the cold air flow divider 50 may be configured as follows: it is provided with one three-adjustable damper capable of rotating 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 flow divider 50 can be further achieved. However, the present disclosure does not exclude a structure having three single-adjustable dampers capable of rotating one damper, and therefore, the cold air flow divider 50 may also be configured as follows: it is provided with three single-adjustable dampers capable of rotating one damper.

[0145] In addition, the opening areas of the large opening, the middle opening, and the small opening of the cold air distribution portion 50 can be appropriately changed for implementation. In addition, the arrangement positions of the large opening, the middle opening, and the small opening can be appropriately changed for implementation.

[0146] This embodiment can be applied not only to a structure including three containers 21, 22, and 23 in the second storage chamber, but also to a structure including four or more containers.

[0147] The first storage room is not limited to the refrigerating room 12, and may be other storage rooms. In addition, the second storage room is not limited to the cold and fresh room 20, and may be other storage rooms.

[0148] The refrigerator 10 may be configured as follows: cold air is not supplied from the front surface of the fresh-keeping room 20, but only from the side surface of the fresh-keeping room 20. That is, the refrigerator 10 may be configured as follows: the cold air supply unit 100, 200, 300, etc. for supplying cold air from the front surface of the fresh-keeping room 20 is not provided, and the cold air supply unit 400 for supplying cold air from the side surface of the fresh-keeping room 20 is provided, and cold air is only supplied from the side surface into the fresh-keeping room 20. In addition, the refrigerator 10 may be configured as follows: the cold air supply unit 400 is provided on at least one of the left side surface and the right side surface of the fresh-keeping room 20. In addition, the height position of the cold air supply unit 400 on the side surface of the fresh-keeping room 20 may be appropriately changed for implementation.

[0149] The above describes a plurality of embodiments of the present invention, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the scope of the invention.
