As shown in FIGS. 2 and 3, two first freezer compartments 721 and 722 are provided side by side in the lower part of the first refrigerator compartment 71. In this embodiment, the first left freezing chamber 721 functions as an ice storage chamber that stores ice supplied from the automatic ice making device 753. The first freezing chamber 722 on the right functions as a switching chamber. The switching chamber is configured such that the cold storage temperature can be arbitrarily switched from a freezing temperature range to a refrigeration temperature range. Therefore, the first freezing compartment 722 on the right functions not only as a freezing compartment but also as a refrigerating compartment.

The first freezing chambers 721 and 722 are circumferentially partitioned by a heat insulating member (a heat insulating plate and an inner heat insulating lid). The first freezing compartments 721 and 722 are provided within the first refrigerating compartment 71. Therefore, in order to maintain the temperature of the first freezing compartments 721 and 722 in a freezing temperature range lower than that of the first refrigerating compartment 71, the first freezing compartments 721 and 722 are insulated by a heat insulating member. The upper portions of the first freezing chambers 721 and 722 are separated by an upper heat insulating plate 251. The lower portions of the first freezing chambers 721 and 722 are separated by a first partition portion 28. The rear portions of the first freezer compartments 721, 722 are separated by a rear heat insulating wall 255 (rear heat insulating plate, see FIG. 5). In this embodiment, the rear heat insulating wall 255 is constituted by a plate-shaped portion of a duct component 31, which will be described later. The sides of the first freezing chambers 721 and 722 are separated by side heat insulating plates (the heat insulating wall 253 and the inner heat insulating wall 252). The front of the first freezer compartments 721, 722 is divided into openable and closable sections by a front lid 15 (inner insulation lid).

As shown in FIG. 5, a protrusion 282 that protrudes upward is provided on the upper surface of the first partition 28. As shown in FIG. The protrusion 282 is provided over substantially the entire width direction of the first freezing chambers 721, 722. The protrusion 282 is provided in a region where the lower portions of the drawer containers 431, 432, which will be described later, are placed in a state where the drawer containers 431, 432 are stored in the first freezer compartments 721, 722. Specifically, the protrusion 282 is provided at a position where the lower surfaces of the front ends of the drawer containers 431, 432 come into contact with each other when the drawer containers 431, 432 are stored in the first freezer compartments 721, 722. . The front surface 283 of the protrusion 282 has a planar shape extending in the vertical direction. A sealing material 284 is adhered to the front surface 283.

An upper heat insulating board 251 is provided above the first freezing chambers 721, 722. An ice-making water supply tank chamber 75 and a chilled chamber 74 are provided above the upper heat insulating board 251. That is, the upper insulation board 251 provides insulation between the ice-making water supply tank chamber 75 and the chilled chamber 74 and the first freezing chambers 721 and 722. As shown in FIG. 3, a heat insulating wall 253 is provided along the left and right side walls 23 and 24 from the left and right ends of the first partition 28 to the lower end of the upper heat insulating plate 251. As shown in FIG. The left and right first freezing chambers 721 and 722 are separated by an inner heat insulating wall 252. The heat insulating wall 253 and the inner heat insulating wall 252 are examples of side heat insulating plates. In addition, when the first freezing compartment 722 on the right does not have the function of a switching compartment, or when there is only one first freezing compartment 72, the internal heat insulating wall 252 may not be provided from the viewpoint of cold storage efficiency.

As shown in FIGS. 4 and 5, drawer containers 431 and 432 are housed in the first freezer compartments 721 and 722, respectively. The front lid 15 of each drawer container 431, 432 has heat insulation performance. The front lid 15 is an example of an internal heat insulation lid. Therefore, the first freezer compartments 721, 722 are insulated by the casing 20, the first partition 28, the upper heat insulating plate 251, and the front lid 15, which have high heat insulation performance, and are kept cool in the freezing temperature range.

The thickness of the upper heat insulating board 251 is thicker than the thickness of the heat insulating wall 253 or the inner heat insulating wall 252. The upper heat insulating board 251 has a built-in heat insulating material that has higher heat insulation performance than the chilled room upper partition section 40 above the chilled room 74 and the ice-making water supply tank room 75. The heat insulating material of the upper heat insulating board 251 includes a vacuum heat insulating material and a molded heat insulating material. The molded heat insulating material is, for example, a porous heat insulating material made of a porous body containing a foamed heat insulating material such as urethane foam or styrofoam, aerogel, xerogel, or cryogel. The molded heat insulating material may be, for example, a heat insulating material composited with a polypropylene foam or a fiber structure. The thickness of the upper heat insulating board 251 is, for example, 1.5 times the thickness of the inner heat insulating wall 252. The thickness of the upper heat insulating board 251 may be thicker than the thickness of the heat insulating wall 253. The thickness of the upper heat insulating board 251 may be thicker than the heat insulating wall 253 and the upper heat insulating board 251.

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

An ice-making water supply tank 751 in which ice-making water is stored is arranged in the ice-making water supply tank chamber 75 and on the side of the chilled chamber 74. An automatic ice making device 753 (see FIG. 4) is installed behind the ice making water supply tank chamber 75. Between the ice-making water tank chamber 75 and the automatic ice-making device 753, there is provided a water tank for supplying water from the ice-making water tank 751 (see FIG. 2) of the ice-making water tank chamber 75 to the water container of the automatic ice-making device 753. A water supply mechanism 752 is provided. The water supply mechanism 752 pumps up water in the ice-making water supply tank 751 by operating a pump, for example, and supplies the pumped water to a water receiving container through a water supply pipe. The water supplied to the water container is supplied to the ice tray of the automatic ice making device 753 via another water supply pipe. Ice made by the automatic ice making device 753 is automatically supplied to the left first freezer compartment 721 and stored.

The chilled chamber 74 is a closed space formed by the chilled chamber top partition 40 and the chilled chamber lid 434. A chilled case 433 (see FIG. 5) is provided inside the chilled chamber 74 and is removable.

The chilled chamber top partition 40 extends substantially horizontally and forms the ceiling of the chilled chamber 74 . The chilled chamber lid 434 is located on the front side of the chilled chamber 74, and is rotatably connected to, for example, the front upper end of the upper partition 40 of the chilled chamber, so that the chilled chamber 74 can be opened and closed. However, the chilled chamber lid 434 is provided integrally with the chilled case 433 instead of being rotatably connected to the chilled chamber upper partition 40, and is moved toward the front of the refrigerator 1 together with the chilled case 433. It may be configured such that it is possible.

The chilled chamber top partition 40 and the chilled chamber lid 434 are made of, for example, a light-transmitting member such as synthetic resin or glass. A heat insulating sheet (not shown) is adhered to the chilled chamber top partition 40 and the chilled chamber lid 434.

A plurality of shelves 45 are provided above the chilled chamber 74 and the ice-making water supply tank chamber 75, and are used as a mounting section for items stored in the first cold storage chamber 71.

As shown in FIGS. 2, 3, and 6, an operation panel 9 is provided at the front of the upper heat insulating board 251. As shown in FIGS. In order to maintain insulation performance between the first refrigerator compartment 71 and the first freezer compartments 721, 722, the upper insulation board 251 is thick. An operation panel 9 is provided on the front of the thick portion of the upper heat insulating board 251. The front surface of the upper heat insulating board 251 is formed with an inclined surface such that the lower part projects more forward than the upper part. An operation panel 9 is provided on the inclined surface. By providing the operation panel 9 on the inclined surface, a large area of the operation panel 9 can be secured. In addition, since the operation panel 9 is provided diagonally upward, a user who opens the revolving doors 11 and 12 and stands in front of the first refrigerator compartment 71 can easily see the operation panel 9 and perform setting operations. .

FIG. 7 shows a front view of an example of the operation panel 9. The operation panel 9 includes a temperature setting button 91 for the first refrigerator compartment 71, a temperature setting button 92 for the first freezing compartment 72, a setting button 93 for the ice making function of the automatic ice maker, a setting button 94 for the chilled compartment 74, and a setting button 94 for the chilled compartment 74. Operation parts such as the cold storage temperature setting button 95 of the first freezer compartment 722, the freezing function button 96 of the first freezer compartments 721 and 722, and these setting display parts 901 to 905, and whether the usage status of the refrigerator 1 is in eco mode or not. A display section 906 or the like is provided to notify the user of the situation. By providing the operation panel 9 in the first refrigerating compartment 71, the user can perform setting operations for the first refrigerating compartment 71 more intuitively. The operation panel 9 shown in FIG. 7 is an example. As another example, a monitor may be provided as an operation panel, and the screen may be switched depending on an arbitrary setting mode.

The left and right revolving doors 11, 12 have surfaces 111, 121 facing the user standing in front of the refrigerator 1 (see FIG. 4), and facing the inside of the first refrigerator compartment 71 in the closed position of the revolving doors 11, 12. It has back surfaces 112 and 122 (inner surfaces on the first refrigerating compartment side). A plurality of pockets 161, 162 are provided on the back surfaces 112, 122.

The lower pockets 161 at the bottom of the left and right revolving doors 11 and 12 are provided at positions facing the first freezer compartments 721 and 722. The lower pocket 161 is provided at a position lower than the upper ends of the first freezer compartments 721 and 722. The lower pocket 161 is an example of a storage shelf. As shown in FIG. 4, the storage shelf is not limited to a pocket type with an open top, but may be any shelf that is attached to the back surface of the revolving doors 11, 12 and can store articles. For example, a shelf that protrudes from the back surface in the depth direction and has a fall prevention bar attached to the protruding end or above the protruding end, or a shelf that protrudes diagonally upward from the back surface of the revolving doors 11 and 12 in the depth direction. It may be a shelf, a shelf with a front door, etc.

Above the lower pocket 161, a plurality of upper pockets 162 are arranged vertically. The upper pocket 162 is provided at a higher position than the tops of the chilled chamber 74 and the ice-making water supply tank chamber 75. The upper pocket is an example of an upper storage shelf. The number of upper pockets 162 is not particularly limited, and may be one stage.

The upper surface of the first partition section 28 constitutes the floor section of the first refrigerating chamber 71. With the drawer containers 431, 432 stored in the first freezing compartments 721, 722, the upper surface of the first partition 28 is widely exposed in front of the first freezing compartments 721, 721. The exposed portion of the upper surface of the first partition portion 28 is referred to as an exposed surface. The exposed surface 281 at the front end of the first partition 28 functions as a highly versatile area. That is, as shown in FIG. 4, when the drawer containers 431, 432 are stored in the first freezer compartments 721, 722 and the revolving doors 11, 12 are opened, the exposed surface 281 is a temporary space for stored items. It can be used as a storage place. Since the exposed surface 281 has a sufficient width, when the drawer containers 431, 432 are pulled forward from the first freezer compartments 721, 722, a wide upper opening of the drawer containers 431, 432 can be secured. For example, if a wall of a building is adjacent to the side where the refrigerator 1 is installed, the revolving doors 11 and 12 cannot be opened at a wide angle. As a result of the refrigerator 1 having the exposed surface 281, the drawer container 431 can be pulled out forward without interfering with the lower pocket 161 even if the rotation angle of the revolving door is about 90 degrees, as shown in FIG. Stored items can be easily retrieved. Therefore, regardless of where the refrigerator 1 is installed, the drawer containers 431 and 432 can be pulled out without the lower pocket 161 interfering. Further, the lower pocket 161 can be provided at the same height as the drawer containers 431 and 432. That is, compared to conventional refrigerators, the range in which pockets can be installed is expanded, and the lower pocket 161 can be provided in front of the first freezer compartment 72. As a result, storage space is secured, and the lower pocket, which is excellent in usability, is provided at a low position, resulting in excellent storage and usability.

The length of the exposed surface 281 in the front-back direction is longer than the length of the lower pocket 161 in the front-back direction. As shown in FIG. 4, the lower pocket 161 is located above the exposed surface 281 when the revolving doors 11 and 12 are closed.

The space above the exposed surface 281 functions as a free space as a temporary storage place for the above-mentioned stored items, a drawer space for the drawer containers 431 and 432, a storage space for the lower pocket 161, and the like.

Both the first refrigerating compartment 71 and the second refrigerating compartment 732 are maintained within the refrigerating temperature range (for example, 1 to 5° C.). The chilled chamber 74 is maintained at a chilled temperature range (for example, 0 to 1° C.). That is, the chilled compartment 74 is cooled to a lower temperature range than the first refrigerating compartment 71 and the second refrigerating compartment 732.

The first cooling mechanism 61 is provided at the rear of the first refrigerator compartment 71. A duct component 31 is provided at the rear of the first refrigerator compartment 71. For example, 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 then to the refrigeration cooler 612 to cool the air flowing through the refrigeration duct D1. A cold air outlet 311 is formed in the duct component 31, and a refrigeration fan 613 is provided near the cold air outlet 311. The cold air cooled within the refrigeration duct D1 is blown out into the first refrigeration compartment 71 from the cold air outlet 311 by the refrigeration fan 613. The cold air blown into the first refrigerating compartment 71 circulates within the first refrigerating compartment 71 and returns into the refrigerating duct D1 from a cold air return port (not shown). Note that in this specification, "sending air to the cooler" is not limited to the case where the air is placed upstream of the cooler in the direction of air flow, and air is sent toward the cooler; This also includes cases in which the air located upstream of the cooler is moved toward the cooler by being placed downstream of the cooler and sending surrounding air further downstream. Similarly, cold air is blown into the chilled chamber 74 from the chilled air supply port 313 . Cold air is blown out from the freezing cold air supply port 312 to the first freezing chambers 721 and 722.

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

The lids 13 and 14 of the second freezer compartment 731 and the second refrigerator compartment 732 and the lids of the first freezer compartments 721 and 722 also have the same heat insulating structure as the revolving doors 11 and 12.

In this specification, "sending air to the cooler" is not limited to cases in which a fan is placed upstream of the cooler in the air flow direction and sends air toward the cooler; This also includes a case where a fan is disposed downstream of the cooler and sends surrounding air further downstream, thereby moving air located upstream of the cooler toward the cooler. The ventilation duct communicates with the refrigerator cooler room. The refrigerator compartment suction port opens to, for example, the second refrigerator compartment 732.

The manner of use of the refrigerator 1 mentioned above will be explained. The user can set the operating temperature range of the first freezer compartment 722 on the right to the freezing temperature range or the refrigeration temperature range. When water is stored in the ice-making water supply tank 751, ice-making processing is performed. That is, water in the ice-making water supply tank 751 is supplied to the water container of the automatic ice-making device 753 via the water supply mechanism 752. The water container is placed in the first freezing chamber 72 and is kept cold in the freezing temperature range to make ice. The produced ice is stored in the drawer container 432 of the first freezer compartment 721 by the operation mechanism of the water container (not shown). The first freezer compartment 72 is kept cool in a lower temperature range than the first refrigerator compartment 71 by the upper heat insulating board 251, the heat insulating boards 252, 253, 254, and the front lid 15. The chilled chamber 74 is kept cool in a different temperature range from the first refrigerator chamber 71 and the first freezing chamber 72 by the chilled chamber upper partition 40, the chilled chamber lid 434, and the upper heat insulating board 251.

The user opens the revolving doors 11 and 12 to store or take out stored items in the first refrigerator compartment 71. When the revolving doors 11, 12 are opened, the front lid 15 of the first freezing compartment 721, 722 and the chilled compartment lid 434 of the chilled compartment 74 cause the first freezing compartment 721, 722 and the chilled compartment lid 434 to open the first freezing compartment. Since the chamber 72 and the chilled chamber 74 are shut off, the rise in temperature in each room is suppressed. When the drawer containers 41, 42 are stored in the first freezer compartments 721, 722, the lower end 151 (front lower end, see FIG. 5) of the back side of the front lid 15 of the first freezer compartment 721, 722 is sealed. contact material 284. Since the front surface 283 of the protrusion 282 and the sealing material 284 are provided in the entire width direction of the first freezing compartments 721, 722, the first freezing compartments 721, 722 have a high cold retention effect. Since the refrigerator 1 includes the first freezing compartment 72 within the first refrigerating compartment 71, the revolving doors 11 and 12 have long dimensions in the vertical direction, and as a result, the lower pocket 161 is disposed at a low position. Therefore, it is easy to store and take out stored items into the lower pocket 161.

In this embodiment, since the automatic ice making device 753 is provided to make ice, the temperature around the front lid 15 tends to drop easily. Since the upper pocket 162 is provided at a higher position than the chilled chamber 74, the influence of cold air is less likely to reach the upper pocket 162. As a result, the upper pocket 162 is not excessively cooled.

Since the lower pocket 161 is provided, the area in front of the front lid 15 is prevented from becoming a dead space, and can be used as a storage space. In other words, the space on the back side of the revolving doors 11 and 12 with different temperature ranges can be provided to the user as a storage space.

The vertical distance between the pockets 161, 162 of each revolving door 11, 12 is larger than the distance between the upper pockets 162, 162 between the lower pocket 161 and the upper pocket 161 of the upper row of the lower pocket 161. . Therefore, relatively tall containers such as drinks can be easily stored in the lower pocket 161.
