The vegetable compartment 4 includes a lower case 4a which is a storage container and an upper case 4b which is located above the lower case 4a and can move in the front-rear direction.
Below the vegetable compartment 4, a frozen storage space for cooling to, for example, -18 to -20 ° C is provided via a heat insulating wall. In the frozen storage space, an ice making chamber 5 provided with an automatic ice making device 5a and an ice storage box 5b and a small freezing chamber (not shown) are arranged side by side. Moreover, the main freezer compartment 6 provided with the lower case 6a and the upper case 6b which are storage containers is arrange | positioned at the lowest stage of frozen storage space. The ice making room 5, the small freezer room, and the main freezer room 6 are also examples of the storage room.

  The front opening of each storage chamber is closed by an independent heat insulating door. Specifically, the front opening of the refrigerator compartment 3 is closed by a so-called double door that is pivotally supported by hinges provided on the upper and lower sides of the left and right sides. The vegetable compartment 4, the ice making compartment 5, the small freezer compartment, and the main freezer compartment 6 are closed by a so-called drawer-type door supported by a rail mechanism provided in the storage compartment. Storage containers are connected to and held by the doors of the vegetable compartment 4, the ice making compartment 5, the small freezer compartment, and the main freezer compartment 6, respectively.

A refrigeration cooler 7 and a refrigeration blower 8 are disposed on the back of the refrigerated storage space that spans the refrigerator compartment 3 and the vegetable compartment 4. Further, the back of the refrigerated storage space straddling the refrigerator compartment 3 and the vegetable compartment 4 is partitioned from the storage compartment by a cold air duct 9, a cooler cover 10 and a blower cover 11. In addition, a refrigeration cooler 12 and a refrigeration blower 13 are disposed on the back of the refrigeration storage space that spans the ice making chamber 5, the small freezer compartment, and the main freezer compartment 6. Further, the back portion of the frozen storage space straddling the ice making room 5, the small freezer room, and the main freezer room 6 is partitioned from the storage room by a cold air duct 14.
A machine chamber 17 that is recessed inward is formed outside the lower back of the heat insulating box 2. The machine room 17 is provided with a compressor 18 that forms part of the refrigeration cycle, a condenser, a radiator fan, and an evaporating dish 16 that evaporates defrost water.

In addition, a control device 19 equipped with a microcomputer for controlling the operation of the refrigerator is installed in the upper part of the machine room 17.
The control device 19 detects detection signals from temperature sensors 20, 21, 22 provided in the refrigerator compartment 3, the vegetable compartment 4, and the main freezer compartment 6, and the opening / closing of the refrigerator compartment 3 and the main freezer compartment 6. Various signals such as detection signals from the detection switches are input. Further, the control device 19 receives a signal such as switching of a cooling mode by a user operation on an operation panel (not shown) installed on the front face of the door of the refrigerator compartment 3. The control device 19 controls the compressor 18 and the refrigerant switching of the refrigeration cycle, the refrigeration blower 8, the refrigeration blower 13, and the display of the operation panel unit based on various input signals and a control program prepared in advance. .

  Next, the flow of cold air when the refrigerator is operated will be described. When the control device 19 drives the compressor 18, in the refrigeration cycle, the refrigerant is supplied to the refrigeration cooler 7 and the refrigeration cooler 12 to cool each to a predetermined temperature. The cold air cooled by the refrigeration cooler 7 is sent to the cold air duct 9 by the refrigeration blower 8, and the cold air inside the refrigerating chamber 3 through a plurality of cold air outlets 9 a provided at appropriate intervals in the vertical direction of the cold air duct 9. To blow out. Thereby, the room is cooled to a predetermined set temperature, for example, about 3 ° C.

  Further, as shown in FIG. 2 showing a perspective view of the chilled room 54, a cold air outlet 9 b is disposed behind the chilled room 54 of the cold air duct 9. Cold air blows out into the chilled room 54 from the cold air outlet 9b in the same manner as cold air blows out into the refrigerator compartment 3 from the cold air outlet 9a. Thereby, the inside of the chilled room 54 is cooled to 0 to 1 ° C., which is a predetermined set temperature.

The cold air circulated in the refrigerator compartment 3 is directed downward from above the refrigerator compartment 3 and reaches the bottom of the refrigerator compartment 3. And it flows in into the vegetable compartment 4 from the inflow port of the cold air opened at the rear part of the bottom plate of the refrigerator compartment 3. The cold air that has flowed into the vegetable compartment 4 flows around the lower case 4 a provided in the vegetable compartment 4, and cools the vegetable compartment 4 to about 7 ° C., for example, which is slightly higher than the temperature of the refrigerator compartment 3. The state of the circulation of the cold air is shown as an arrow A in FIG.
The defrosting of the refrigeration cooler 7 is performed at 0 ° C. or higher in the refrigeration room 3 and the vegetable room 4 by operating the refrigeration blower 8 with the refrigerant flowing into the refrigeration cooler 7 stopped. This is done by circulating air at a temperature of.

  A cold air duct 14 for circulating cold air is disposed on the back of the heat insulating box 2, which is the rear part of the ice making room 5, the small freezer room and the main freezer room 6. The frozen storage space is cooled as follows. That is, the cold air cooled by the refrigerating cooler 12 is blown by the refrigerating blower 13 along the cold air duct 14 toward each freezer compartment. Thereafter, the cold air that has cooled the freezing space is directed downward in the freezer compartment, is sucked into a suction port 26 provided below the cold air duct 14, and is cooled again by the freezing cooler 12. Such cold air circulation is repeated by the refrigeration blower 13. Thereby, the frozen storage space is cooled. The state of the circulation of the cold air is shown as an arrow B in FIG.

  In addition, below the freezing cooler 12, a dewatering heater 15 and a drainage tub that receives defrosted water are disposed. The defrosting of the refrigeration cooler 12 is performed by stopping the operation of the compressor 18 and stopping the inflow of the refrigerant to the refrigeration cooler 12 by radiating heat from the defrost heater 15. This is done by heating. At this time, the melted defrost water is discharged to the external evaporating dish 16 by a drainage tub (not shown).

  FIG. 3 is a perspective view showing the chilled case 51 with the partition member 61. The chilled case 51 is provided with a handle portion 55 at the front upper portion over the entire width of the chilled case 51 in the left-right direction. The user puts the hand on the handle portion 55 and pulls the chilled case 51 in the front-rear direction, thereby storing and taking out stored items in the chilled case 51.

  At the upper end of the left and right side surfaces of the chilled case 51 and the upper end of the rear surface, flanges are formed in the direction from the inside toward the outside. On the bottom surface of the chilled case 51, there are formed feet 56 that hang downward and extend in the front-rear direction. In this case, the foot portions 56 are provided on the bottom surfaces of the left and right ends that are outside the storage space in the chilled case 51. Although the chilled case 51 is placed on the bottom surface of the refrigerator compartment 3, the entire bottom surface portion of the chilled case 51 does not contact the bottom surface of the refrigerator compartment 3, but the foot portion 56 contacts the bottom surface of the refrigerator compartment 3. Therefore, a gap corresponding to the height of the foot portion 56 is formed between the bottom surface of the chilled case 51 and the bottom surface of the refrigerator compartment 3.

The partition member 61 is fixed by being engaged with the upper end edge on the rear side of the chilled case 51, and is divided by partitioning the inside of the chilled case 51 in the front-rear direction and the vertical direction. Thereby, the inside of the chilled case 51 is partitioned into left and right independent spaces.
The user can appropriately change the capacity of the left and right spaces in the chilled case 51 by moving the partition member 61 while sliding along the upper edge of the chilled case 51. Alternatively, the user removes the partition member 61 from the chilled case 51 and engages and fixes the partition member 61 at a desired position on the upper edge of the chilled case 51 to appropriately change the capacity of the left and right spaces in the chilled case 51. be able to.

  As shown in FIG. 4, which is a perspective view of the partition member 61, the partition member 61 includes a partition main body 62 and a fixing portion 63. The fixing part 63 is provided with a groove part 64 extending along the longitudinal direction of the fixing part 63. The partition main body 62 is provided with an engaging portion 65 extending in the vertical direction at one end of the partition main body 62. The engaging portion 65 is provided with a ridge portion 65 a that extends along the longitudinal direction of the engaging portion 65 and fits into the groove portion 64. The partition member 61 integrally forms the partition main body 62 and the fixing portion 63 by engaging the groove portion 64 provided in the fixing portion 63 and the engaging portion 65 provided in the partition main body 62. Specifically, as shown in FIG. 5, which is a perspective view showing the fixing portion 63, there is a portion where the groove portion 64 is not formed at the lower end of the groove portion 64 of the fixing portion 63. The user inserts the engaging portion 65 of the partition main body 62 while sliding from above so as to fit the groove portion 64 of the fixing portion 63. And the lower end of the groove part 64 of the fixing | fixed part 63 and the lower end of the engaging part 65 of the partition main body 62 are contact | abutted, and an engagement state is hold | maintained. Here, the vertical dimension of the groove portion 64 and the engaging portion 65 is such that the upper end of the fixing portion 63 and the upper end of the partition main body 62 are substantially the same in a state where the fixing portion 63 and the partition main body 62 are engaged and held. The dimensions are as follows.

A clip portion 66 is provided on the side of the fixing portion 63 opposite to the side engaging with the partition main body 62. The clip portion 66 sandwiches the chilled case 51 from the inside and the outside and stably maintains the fixed state of the partition member 61.
In addition, as a material of the partition main body 62 and the chilled case 51, a good-looking and high-strength polystyrene is used. As a material of the fixing part 63, polypropylene which is a softer material than polystyrene is used. However, the material of the partition main body 62, the chilled case 51, and the fixing | fixed part 63 is not restricted to the material mentioned above. In addition, it is preferable to use a soft material as the material of the fixing portion 63 as compared with the material of the chilled case 51.

The fixing part 63 of the partition member 61 is formed of polypropylene which is a soft material compared to polystyrene which is a material used for the chilled case 51. Therefore, when the partition member 61 is slid to arbitrarily divide the chilled case 51, the chilled case 51 is hardly damaged even if the fixing portion 63 is slid on the edge of the chilled case 51.

  The partition member 61 is composed of two members, a partition main body 62 and a fixing portion 63. Therefore, a structure for fixing the two members to each other, in this case, by sharing the structure of the groove portion 64 and the engaging portion 65, the partition main body 62 having a different shape can be fitted to the same fixing portion 63. Can do. Thereby, the shape of the partition member 61 can be changed. Alternatively, the partition main body 62 can be applied to storage cases other than the chilled case 51 such as containers and door pockets in the vegetable compartment 4 by changing the fixing portion 63 to another shape. Therefore, the parts used for the partition can be shared.

  When the partition member 61 becomes dirty, only the partition main body 62 that easily comes into contact with the stored item among the partition members 61 can be removed from the fixing portion 63 and washed. Therefore, maintenance is easy and it is easy to keep the storage space clean.

(Second embodiment)
The difference from the first embodiment described above is that the partition member is provided with a duct 69 for guiding cool air.
As shown in FIG. 7 showing the partition member 67 of the second embodiment, the partition main body 68 constituting the partition member 67 is provided with a duct 69 having a U-shaped cross section at the rear upper part thereof. The duct 69 includes two surface portions 69a and 69b that face each other in the vertical direction, and a surface portion 69c that connects end portions on the protruding side of the surface portions 69a and 69b. In this case, the duct 69 has a substantially triangular shape with a large opening on the rear side and a gradually decreasing opening toward the front. Further, the duct 69 is positioned at the height of the cold air outlet 9b, and divides the space at a position higher than the height from the bottom surface to the upper end of the chilled case 51.

The cool air supplied into the chilled case 51 from the cool air outlet 9b by the duct 69 is sent to one of the partitioned areas in the chilled case 51, in this case, the area where the duct 69 is not provided. It is done. With this configuration, the amount of cool air flowing into the chilled case 51 can be adjusted for each space partitioned from the partition member 67 into the right side and the left side. Therefore, the user can control the temperature of each space partitioned by appropriately adjusting the position of the partition member 67. Furthermore, the height of the partition member 67 is higher than the height of the chilled case 51. Therefore, the partition member 67 restricts cool air from flowing back and forth in the upper region of the chilled case 51. Therefore, spaces having different temperatures can be created in one chilled case 51. Therefore, the user can select and store a space having a temperature more suitable for the stored item.
The shape of the duct 69 is not limited to a U-shaped cross section, and may be any shape that can guide cool air to a specific region. For example, a semicircular duct having a U-shaped cross section may be provided.

According to the refrigerator of at least one embodiment described above, the fixing portion 63 of the partition members 61 and 67 is made of a softer material than the material used for the chilled case 51. Therefore, when the partition members 61 and 67 are slid to arbitrarily divide the chilled case 51, the chilled case 51 is hardly damaged even if the fixing portion 63 is slid on the edge of the chilled case 51.
Further, the members attached to the fixing portion 63 are not limited to the partition main bodies 62 and 68. For example, a camera or an illuminating device for imaging the inside of a refrigerator may be provided with an engaging portion as an attachment structure, and then attached and fixed to containers such as a storage case via the engaging portion.

  Although this embodiment demonstrated the case where the partition members 61 and 67 were provided in the chilled case 51 as an example, the place provided with the partition members 61 and 67 is not restricted to the chilled case 51. For example, you may provide the partition members 61 and 67 in each storage case in storage rooms of freezing temperature zones, such as the vegetable compartment 7 and a small freezer compartment.
