As shown in fig. 2 and 3, two first freezing

chambers

721 and 722 are provided in parallel on the left and right sides of the lower portion of first refrigerating chamber 71. In the present embodiment, the left first freezing chamber 721 functions as an ice storage chamber for storing ice supplied from the automatic ice making device 753. First freezing chamber 722 on the right side functions as a switching chamber. The switching chamber is configured to be capable of arbitrarily switching the cold insulation temperature in a section from the freezing temperature zone to the cold storage temperature zone. Therefore, the right first freezing chamber 722 functions as a refrigerating chamber in addition to the freezing chamber.

The surroundings of the first freezing

chamber

721, 722 are divided by heat insulating members (heat insulating plates and inner heat insulating covers). The first freezing

chamber

721, 722 is provided inside the first refrigerating chamber 71. Therefore, the first freezing

chamber

721 or 722 is insulated by the heat insulating member in order to keep the temperature thereof in a freezing temperature range lower than that of the first refrigerating chamber 71. The upper portion of the first freezing

chamber

721, 722 is divided by an upper heat insulation plate 251. The lower portion of the first freezing

chamber

721, 722 is divided by the first partition 28. The rear of the first freezing

chamber

721, 722 is divided by a rear heat insulating wall 255 (rear heat insulating panel, refer to fig. 5). In the present embodiment, the rear heat insulating wall 255 is formed of a plate-like portion of the duct member 31 described later. The sides of the first freezing

chamber

721, 722 are divided by side heat insulating panels (the heat insulating wall 253 and the inner heat insulating wall 252). The front of first freezing

chamber

721, 722 is partitioned by front cover 15 (inner heat insulating cover) so as to be openable and closable.

As shown in fig. 5, a projection 282 projecting upward is provided on the upper surface of the first partition 28. The protrusion 282 is provided over substantially the entire area in the lateral width direction of the first freezing

chamber

721, 722. The projection 282 is provided in a region where the lower portion of the

drawer container

431, 432 is disposed in a state where the

drawer container

431, 432 is housed in the first freezing

chamber

721, 722, which will be described later. Specifically, the protrusion 282 is provided at a position where the lower surfaces of the front end portions of the

drawer containers

431 and 432 contact with each other in a state where the

drawer containers

431 and 432 are housed in the first freezing

chambers

721 and 722. The front surface 283 of the protrusion 282 has a planar shape along the up-down direction. A sealing material 284 is bonded to the front surface 283.

An upper heat insulation plate 251 is disposed above the first freezing

chamber

721, 722. A water supply tank chamber 75 for ice making and a fresh air chamber 74 are provided above the upper heat insulation plate 251. That is, the ice-making water supply tank chamber 75 and the fresh air chamber 74 are insulated from the first freezing

chambers

721 and 722 by the upper heat insulating plate 251. As shown in fig. 3, the heat insulating wall 253 is provided along the left and

right side walls

23, 24 from the left and right end portions of the first partition portion 28 to the lower end of the upper heat insulating plate 251. The left and right first freezing

chambers

721, 722 are partitioned by an inner heat insulating wall 252. The heat insulating wall 253 and the inner heat insulating wall 252 are examples of heat insulating plates on the side portions. When first freezing chamber 722 on the right side does not have the function of switching chambers, or when first freezing chamber 72 is a single chamber, inner heat insulating wall 252 may not be provided from the viewpoint of cooling efficiency.

As shown in fig. 4 and 5,

drawer containers

431 and 432 are respectively housed in the first freezing

chambers

721 and 722. The front cover 15 of each

drawer container

431, 432 has heat insulating properties. The front cover 15 is an example of an inner heat insulating cover. Therefore, the first freezing

chambers

721 and 722 are insulated by the casing 20 having high insulation performance, the first partition 28, the upper insulation board 251, and the front cover 15, and kept cold at the freezing temperature range.

The upper insulation panel 251 has a thickness thicker than that of the insulation wall 253 or the inner insulation wall 252. The upper heat insulation plate 251 has a heat insulation material therein, which has a higher heat insulation performance than the upper surface partition portion 40 of the fresh ice compartment 74 and the ice-making water supply tank compartment 75. The insulation material of the upper insulation panel 251 is composed of a vacuum insulation material and a molded insulation material. The molded heat insulating material is, for example, a foamed heat insulating material such as foamed polyurethane or foamed styrene, or a porous heat insulating material composed of a porous body containing aerogel, xerogel, or crystal gel. The molded heat insulating material may be, for example, a heat insulating material formed by compounding a polypropylene foam or a fibrous structure. The thickness of the upper heat insulating plate 251 is, for example, 1.5 times the thickness of the inner heat insulating wall 252. The upper insulation plate 251 may have a thickness thicker than that of the insulation wall 253. The upper insulation panel 251 may have a thickness thicker than the insulation walls 253 and the inner insulation walls 252.

The water supply tank chamber 75 for ice making is provided adjacent to the left side wall 23 above the left first freezing chamber 721. The fresh water chamber 74 is provided between the ice-making water supply tank chamber 75 and the right side wall 24. The upper portions of the fresh water chamber 74 and the ice-making water supply tank chamber 75 are partitioned by a fresh water chamber upper surface partition 40 provided substantially in the horizontal direction. The fresh water chamber 74 and the water supply tank chamber 75 for ice making are partitioned from the first freezing chamber 72 by an upper heat insulation plate 251. As shown in fig. 3, the fresh water compartment 74 and the water supply tank compartment 75 for ice making are partitioned by a water supply tank compartment partition 254 (heat insulating member, heat insulating wall) provided substantially in the vertical direction.

The ice-making water supply tank 751 for storing ice-making water is disposed in the ice-making water supply tank compartment 75 and on the side of the fresh water compartment 74. An automatic ice making device 753 (see fig. 4) is provided behind the ice-making water supply tank compartment 75. A water supply mechanism 752 for supplying water in the ice making water supply tank 751 (see fig. 2) of the ice making water supply tank 75 to the water container of the automatic ice making device 753 is provided between the ice making water supply tank 75 and the automatic ice making device 753. The water supply mechanism 752 draws up water in the ice-making water supply tank 751 by, for example, the operation of a pump, and supplies the drawn water to the water container through a water supply pipe. The water supplied to the water container is supplied to the ice making tray of the automatic ice making device 753 via another water supply pipe. The ice made by the automatic ice making device 753 is automatically supplied and stored toward the left first freezing chamber 721.

With respect to the fresh air chamber 74, a closed space is formed by the fresh air chamber upper surface partition 40 and the fresh air chamber cover 434. A fresh ice box 433 (see fig. 5) is provided in the fresh ice chamber 74 so as to be able to be put in and taken out.

The fresh air compartment upper surface partition 40 extends substantially horizontally to form a top of the fresh air compartment 74. The fresh air chamber cover 434 is located on the front side of the fresh air chamber 74, and is rotatably connected to the front upper end of the fresh air chamber upper surface partition 40, for example, to openably close the fresh air chamber 74. However, instead of being rotatably connected to the fresh air chamber upper surface partition 40, the fresh air chamber cover 434 may be integrally provided with the fresh air box 433 and be configured to be movable toward the front of the refrigerator 1 integrally with the fresh air box 433.

The fresh air chamber upper surface partition 40 and the fresh air chamber cover 434 are formed of, for example, a translucent synthetic resin, glass, or the like. A heat insulating sheet, not shown, is bonded to the fresh air chamber upper surface partition 40 and the fresh air chamber lid 434.

A plurality of shelves 45 are provided above the fresh water chamber 74 and the ice-making water supply tank chamber 75, and serve as placement portions for articles stored in the first refrigerating chamber 71.

As shown in fig. 2, 3, and 6, an operation panel 9 is provided in front of the upper heat insulation board 251. In order to secure the insulation performance between the first refrigerating chamber 71 and the first freezing

chambers

721 and 722, the upper insulation board 251 has a thick thickness. The operation panel 9 is provided on the front surface of the thick portion of the upper heat insulation board 251. The front surface of the upper heat insulation plate 251 is formed as an inclined surface inclined such that the lower portion protrudes forward from the upper portion. The operation panel 9 is provided on the inclined surface. The operation panel 9 is provided on the inclined surface, so that the area of the operation panel 9 can be secured wide. Further, since the operation panel 9 is provided so as to face obliquely upward, a user who opens the

swing doors

11 and 12 and stands in front of the first refrigerating compartment 71 can easily visually confirm the operation panel 9 and perform a setting operation.

Fig. 7 is a front view showing an example of the operation panel 9. The operation panel 9 is provided with: operation units such as a temperature setting button 91 in first refrigerating compartment 71, a temperature setting button 92 in first freezing compartment 72, an ice making function setting button 93 of an automatic ice making device, a setting button 94 in fresh ice compartment 74, a cold insulation temperature setting button 95 in right first freezing compartment 722, freezing function buttons 96 in first freezing

compartments

721 and 722, setting display units 901 to 905 thereof, and a display unit 906 for informing whether or not the usage status of refrigerator 1 is in the energy saving mode. Operation panel 9 is provided in first refrigerating compartment 71, whereby a user can more intuitively perform a setting operation of first refrigerating compartment 71. The operation panel 9 shown in fig. 7 is merely an example. As another example, a monitor may be provided as an operation panel, and the screen may be switched according to an arbitrary setting mode.

The left and

right swing doors

11 and 12 include: surfaces 111, 121 (see fig. 4) opposed to a user standing on the front face of the refrigerator 1; and rear surfaces 112 and 122 (inner surfaces of the first refrigerating chamber side) opposed to the inside of the first refrigerating chamber 71 at positions where the

swing doors

11 and 12 are closed. A plurality of

door storage boxes

161, 162 are provided on the back surfaces 112, 122.

The lowermost lower-stage door pocket 161 of the left and

right swing doors

11, 12 is provided at a position facing the first freezing

chamber

721, 722. The lower door storage box 161 is disposed at a position lower than the upper end of the first freezing

chamber

721, 722. The lower door pocket 161 is an example of a storage shelf. The storage shelf is not limited to a box type with an upper opening as shown in fig. 4, and may be any shelf that is attached to the back surface of the

swing doors

11 and 12 and can store articles. For example, the rack may be a rack that protrudes from the back surface in the depth direction, and has a bar attached to the protruding end portion or above the protruding end portion to prevent the bar from falling down, and a rack that protrudes from the back surface of the revolving

doors

11 and 12 obliquely upward as it goes toward the depth direction may be a rack having a front door; and the like.

A plurality of upper door storage boxes 162 are arranged above the lower door storage box 161 in an up-down arrangement. The upper-door bin 162 is disposed at a position higher than the upper portions of the fresh water compartment 74 and the water supply compartment 75 for ice making. The upper door storage box is an example of an upper storage shelf. The number of the upper box door storage boxes 162 is not particularly limited, and may be one layer.

The upper surface of the first partition 28 constitutes the bottom of the first refrigerating chamber 71. In a state where

drawer containers

431 and 432 are housed in first freezing

chambers

721 and 722, the upper surface of first partitioning portion 28 is widely exposed in front of first freezing

chambers

721 and 721. The exposed portion of the upper surface of the first partition 28 is referred to as an exposed surface. The exposed surface 281 of the exposed tip portion of the first partition portion 28 functions as a region having high versatility. That is, as shown in fig. 4, in a state where the

drawer containers

431 and 432 are accommodated in the first freezing

chambers

721 and 722 and the revolving

doors

11 and 12 are opened, the exposed surface 281 can be used as a temporary storage place for the stored material. By providing the exposed surface 281 with a sufficient width, when the

drawer containers

431 and 432 are pulled out forward from the first freezing

chambers

721 and 722, a wide opening of the upper portions of the

drawer containers

431 and 432 can be ensured. For example, when the side of the installation place of the refrigerator 1 approaches the wall of the building, the

swing doors

11 and 12 cannot be opened at a large angle. As a result, as shown in fig. 6, even when the rotation angle of the swing door is about 90 degrees, the drawer container 431 can be pulled out forward without interfering with the lower door pocket 161, and the stored articles can be easily taken out by providing the exposed surface 281 to the refrigerator 1. Therefore, regardless of the installation place of the refrigerator 1, the

drawer containers

431 and 432 can be drawn out without interfering with the lower door pocket 161. Further, the lower door pocket 161 can be provided at the same height as the

drawer containers

431 and 432. That is, the range in which the door storage box can be provided is wider than that of the conventional refrigerator, and the lower door storage box 161 can be provided in front of the first freezing chamber 72. As a result, the lower door pocket, which can secure a storage space and is excellent in usability, is provided at a low position, and therefore, the storage property and the usability are excellent.

The length of the exposed surface 281 in the front-rear direction is longer than the length of the lower door pocket 161 in the front-rear direction. As shown in fig. 4, in a state where the

swing doors

11 and 12 are closed, the lower door pocket 161 is positioned above the exposed surface 281.

The space above the exposed surface 281 functions as a free space as a temporary storage place for the stored articles and the like, a drawing space of the drawing

containers

431 and 432, a storage space of the lower door pocket 161, and the like.

Both first refrigerating room 71 and second refrigerating room 732 are kept at a refrigerating temperature range (e.g., 1 to 5 ℃). The freezing chamber 74 is maintained at a freezing temperature range (e.g., 0-1 ℃). That is, fresh air compartment 74 is cooled to a temperature zone lower than that of first refrigerating compartment 71 and second refrigerating compartment 732.

The first cooling mechanism 61 is disposed behind the first refrigerating compartment 71. A duct member 31 is provided at the rear of the first refrigerating compartment 71. For example, the refrigerant gas compressed by the compressor 60 provided in the machine room at the bottom of the refrigerator 1 is supplied to the duct D3 and to the refrigerating cooler 612, and cools the air flowing through the refrigerating duct D1. Cold air outlet 311 is formed in duct member 31, and cooling fan 613 is provided near cold air outlet 311. The cold air cooled in cold storage duct D1 is blown out by cold air fan 613 from cold air outlet 311 into first cold storage room 71. The cold air blown out into first refrigerator compartment 71 circulates in first refrigerator compartment 71, and is returned from a cold air return port (not shown) into cold storage duct D1. In the present specification, the phrase "blowing air to the cooler" is not limited to the case where the air is blown to the cooler while being arranged on the upstream side of the cooler in the air flow direction, but also includes the case where the air is arranged on the downstream side of the cooler in the air flow direction, and the air located on the upstream side of the cooler is moved to the cooler by sending the surrounding air further to the downstream side. Similarly, cold air is blown out from the cold air supply port 313 for fresh ice toward the fresh air compartment 74. Cold air is blown out from cold air supply port 312 for freezing toward first freezing

chambers

721 and 722.

The second cooling mechanism 62 is disposed behind the second freezing chamber 731. A duct member 32 is provided at the rear of the lower storage chamber 73. Similarly to the first cooling mechanism 61, the refrigerant gas supplied to the duct D3 is supplied to the refrigeration cooler 622, and cools the air flowing through the duct D2 for the lower storage compartment. The cold air cooled in duct D2 for the lower storage compartment is blown out from cold air outlet 321 into second freezing chamber 731 by freezing fan 623.

The

covers

13 and 14 of the second freezing chamber 731 and the second refrigerating chamber 732 and the covers of the first freezing

chambers

721 and 722 also have the same heat insulating structure as the revolving

doors

11 and 12.

In the present specification, the phrase "blowing air to the cooler" is not limited to the case where the fan is disposed on the upstream side of the cooler in the air flow direction and the air is blown to the cooler, and includes the case where the fan is disposed on the downstream side of the cooler in the air flow direction and the air on the upstream side of the cooler is moved to the cooler by sending the surrounding air further to the downstream side. The air supply duct is communicated with the cooler chamber for cold storage. The refrigerating compartment suction port is opened in the second refrigerating compartment 732, for example.

The use of the refrigerator 1 described above will be explained. The user can set the use temperature band of the first freezing compartment 722 on the right side to a freezing temperature band or a refrigerating temperature band. The ice making process can be performed by storing water in the ice making water supply tank 751 in advance. That is, water in the ice-making water supply tank 751 is supplied to the water container of the automatic ice-making device 753 through the water supply mechanism 752. The water container is disposed in first freezer compartment 72 and is kept cold at a freezing temperature range, so that ice can be made. As for the ice to be produced, the ice in the water container is stored in the drawer container 432 of the first freezing chamber 721 by an operation mechanism of the water container, not shown. The first freezing compartment 72 is kept cold at a lower temperature zone than the first refrigerating compartment 71 by means of the upper heat insulation plate 251, the

heat insulation plates

252, 253, 254 and the front cover 15. The freezing chamber 74 is cooled at a temperature band different from that of the first refrigerating chamber 71 and the first freezing chamber 72 by the freezing chamber upper surface partition 40, the freezing chamber cover 434, and the upper heat insulation plate 251.

The user opens the

swing doors

11 and 12 to store or take out the stored items in or from the first refrigerating compartment 71. When the

rotary doors

11 and 12 are opened, the front covers 15 of the first freezing

chambers

721 and 722 and the fresh air chamber cover 434 of the fresh air chamber 74 block the first freezing chamber 72 and the fresh air chamber 74 through the first freezing

chambers

721 and 722 and the fresh air chamber cover 434, and therefore, increase in the indoor temperatures of the respective chambers can be suppressed. In a state where the

drawer containers

41 and 42 are housed in the first freezing

chambers

721 and 722, the lower end portion 151 (front lower end portion, see fig. 5) on the back side of the front cover 15 of the first freezing

chambers

721 and 722 is in contact with the sealant 284. The front surface 283 of the protrusion 282 and the sealing material 284 are integrally provided in the lateral width direction of the first freezing

chamber

721, 722, and thus the first freezing

chamber

721, 722 has a high cooling effect. Since the refrigerator 1 includes the first freezing chamber 72 in the first refrigerating chamber 71, the vertical dimension of the

swing doors

11 and 12 is long, and as a result, the lower door pocket 161 is disposed at a low position. Therefore, the stored articles can be easily stored in or taken out from the lower door storage box 161.

Since the exposed surface 281 is widely exposed in a state where the

rotary doors

11 and 12 are opened and the first freezing

chambers

721 and 721 are closed, the user can use the exposed surface 281 as a temporary storage place for the stored material.

Since the exposed surface 281 is widely provided in front of the first freezing

chamber

721 or 722, the user can easily pull out the

drawer containers

431 or 432 without interfering with the lower door pocket 161 even if the user does not open the

swing doors

11 or 12 at the maximum angle when taking out the stored materials in the first freezing

chamber

721 or 722.

With such a configuration, the refrigerator 1 can ensure heat insulation and improve convenience of the refrigerator 1.

According to the above-described embodiment, the refrigerator 1 includes: a first refrigerating compartment 71; a first freezing chamber 72 disposed in the first refrigerating chamber 71 and kept cold at a freezing temperature range; and the lower storage chamber 73, convenience can be improved.

According to the above embodiment, first freezing chamber 72 is disposed in first refrigerating chamber 71 in the upper part of refrigerator 1, and the lower end of first refrigerating chamber 71 is disposed at a lower position than in the conventional refrigerator. As a result, as described below, the convenience of the user can be improved.

According to the above-described embodiment, the first freezing

chamber

721, 722 is provided inside the first refrigerating chamber 71, and therefore, the number of doors or covers can be reduced as compared with the conventional refrigerator in which a small freezing chamber is separately provided. As a result, the refrigerator 1 is improved in design. That is, the vertical dimension of the revolving door can be increased as compared with a conventional refrigerator in which a small freezing chamber is separately provided, and as a result, the lower end position of the revolving door can be lowered significantly. Thus, the design of the refrigerator can be improved. Further, first freezing

chambers

721 and 722 are provided in first refrigerating chamber 71, and the vertical dimension of the revolving door is increased. As a result, the number of the storage boxes of the box door can be increased. Further, since the height of the lower door pocket 161 is lowered, a user can easily put or take out a heavy storage such as a beverage bottle into or from the first refrigerating chamber 71. As a result, the convenience in use of the refrigerator 1 is improved.

According to the above-described embodiment, the first freezing

chamber

721, 722 and the fresh air chamber 74 are provided within the first refrigerating chamber 71. As a result, for example, the operation of moving the stored material originally stored in the fresh food compartment 74 to the first freezing compartment 722 immediately below and freezing the stored material, or conversely, moving the stored material originally stored in the first freezing compartment 722 to the fresh food compartment 74 and thawing the stored material for cooking can be completed only by one door opening and closing operation. Therefore, a new usage trajectory that does not exist in the existing refrigerator can be provided, and convenience in use is improved.

According to the above embodiment, since the plurality of first freezing chambers 72 are provided and the automatic ice making device 753 is provided in at least one first freezing chamber 721, the automatic ice making device 753 and the first freezing chamber 721 for storing ice can be provided in the first refrigerating chamber 71. As a result, the water supply path between the ice making water tank and the automatic ice making device can be shortened, and space saving of the automatic ice making device can be achieved.

According to the above embodiment, since a plurality of first freezing chambers 72 are provided and at least one first freezing chamber 722 is a switching chamber, the user can arbitrarily change the setting of first freezing chamber 72 according to the usage mode. As a result, the convenience in use of the refrigerator 1 is improved.

According to the above embodiment, since operation panel 9 is provided in first refrigerating room 71, the states of adjacent first freezing room and fresh-ice room 74 can be displayed, and the state in first refrigerating room 71 can be visually recognized. In the conventional refrigerator, the operation panel is provided on a decorative panel of an outer surface of the door or an inner wall of the refrigerating chamber. However, in the refrigerator of the above embodiment, since operation panel 9 is provided at a position adjacent to the upper side of first freezer compartment 72, user can easily see operation panel 9. Also, the user can intuitively recognize the state of the first refrigerating compartment 71. As a result, convenience in use of the refrigerator is improved. Since the operation panel 9 is provided in the thickness portion of the heat insulating partition formed in the first refrigerating compartment 71, the operation panel can be provided without reducing the storage space of the first refrigerating compartment 71.

According to the above embodiment, the upper surface of the first partition 28 constituting the bottom of the first refrigerating compartment 71 is widely exposed as the exposed surface 281. Therefore, the drawing trajectory of the first freezing

chamber

721, 722 can be secured, and convenience in use is improved. In addition, in the state where the

swing doors

11 and 12 are closed, the storage space of the lower box door pocket 161 can be effectively used. Therefore, the lower door pocket 161 can be made large. In a state where the

swing doors

11 and 12 are opened, the user can temporarily place an article on the exposed surface 281. As a result, convenience in use of the refrigerator is improved.

According to the above embodiment, the upper door pocket 162 is provided at a position higher than the fresh air compartment 74 on the

rear surfaces

112 and 122 of the

swing doors

11 and 12, so that the accommodation performance of the

swing doors

11 and 12 is high. In the present embodiment, since ice is made by providing the automatic ice making device 753, the temperature around the front cover 15 tends to be easily lowered. Since the upper door bank 162 is disposed at a position higher than the fresh air compartment 74, the influence of the cold air is hard to be exerted on the upper door bank 162. As a result, the upper door storage box 162 is not excessively cooled.

Since the lower door pocket 161 is provided, the region in front of the front cover 15 can be prevented from becoming a dead space, and can be used as a storage space. That is, the areas with different temperature zones in the spaces on the back sides of the

swing doors

11 and 12 can be provided to the user as storage locations.

With respect to the longitudinal interval of the respective door pockets 161, 162 of the

respective swing doors

11, 12, the interval between the lower door pocket 161 and the upper door pocket 161 on the upper layer of the lower door pocket 161 is larger than the interval between the upper door pockets 162, 162. Therefore, a relatively high-ratio container such as a beverage can be easily stored in the lower door pocket 161. As described above, the lower door pocket 161 is located in a region where the temperature of the periphery of the front cover 15 is likely to decrease, and therefore can be used as a rapid cooling region of a 500ml can, for example.

In the above embodiment, an example in which the first freezing

chamber

721, 722 is provided in the lower portion of the first refrigerating chamber 71 is shown. However, the position of the first freezer compartment in the first refrigerator compartment is not limited to the lower part, and the first freezer compartment may be disposed on the upper part of the first refrigerator compartment, for example.

The upper door pocket 162 is disposed above the fresh water compartment 74 and the ice-making water supply compartment 75, but this configuration is not essential. For example, the upper-door pocket may be located below the fresh water compartment 74 and the ice-making water supply compartment 75. Further, the following configuration may be adopted: the upper door pockets are provided to be detachable from the

swing doors

11 and 12, and are appropriately attached to the upper side or the lower side of the fresh water compartment 74 and the water supply tank compartment 75 for ice making in accordance with the user's demand.

In the above embodiment, the example in which 2 cooling mechanisms are provided in the refrigerator is shown, but the number of cooling mechanisms is not limited as long as the number is 1 or more.

In the above embodiment, the example in which the sealing material 284 is bonded to the front surface 283 of the protrusion 282 of the first partition 28 has been described, but the sealing material 284 may be provided between the first partition and the front end portion of the drawer container. For example, a sealing material may be bonded to the back surface of the lower end portion of the front cover 15. Further, the following configuration may be adopted: the first partition does not have a projection, and the sealing material is directly attached to the upper surface of the first partition and the lower surface of the front cover 15 or the drawer container, and the first partition and the lower surface of the front cover or the drawer container are in contact with the sealing material.

In the above-described embodiment, the example in which the fresh air chamber 74 is provided above the first freezing chamber is shown, but the fresh air chamber 74 is not necessarily configured. For example, as shown in fig. 8, instead of providing the fresh air compartment 74, the upper portion of the upper heat insulation plate 251 may be used as a shelf.

In the above embodiment, the example in which the two first freezing

chambers

721 and 722 are arranged in the left-right direction is shown, but the first freezing chamber is not limited to this configuration example. For example, when two or more first freezing compartments are provided, the plurality of first freezing compartments may be arranged vertically. The first freezing chamber may be one. In addition, an ice storage container for storing ice may be provided in one first freezing chamber.
