Reference numerals 3 and 54 are arranged above and below the freezer compartment 12 to store frozen food, ice cream, and the like.

The partition plate 44, the cooler 47 and the blower 4
8, a cooling air distribution duct 56 is formed. In the partition plate 44, freezing room cold air discharge ports 57 and 58 communicating with the duct 56 and the freezing room 12 are provided at the upper and lower portions of the containers 53 and 54. Open correspondingly. Further, on the lower surface of the heat insulating partition wall 9, a freezing room cool air duct 64 communicating with the duct 56 is formed. An automatic ice maker 61 is attached to the upper part of the freezing compartment 12, and cool air is supplied to the automatic ice maker 61 from a free air outlet 57 of the freezing compartment. In addition, a freezer compartment cool air return port 63 communicating with the lower portion of the cooling compartment 46 is formed behind the container 54.

In the upper part of the duct 56, a cool air distribution port 66 is formed on the side of the blower 48.
The communication duct 67 rising from 6 communicates with the lower end of the refrigerator compartment duct 24 behind the vegetable compartment 11. A motor-driven damper 68 is mounted in the communication duct 67 in front of the discharge ports 26 and 25 and the bypass duct 36, and is located behind the vegetable compartment 11.

A refrigerator / vegetable compartment cool air return duct 71 is formed on the right side of the cooler 47, and the upper end thereof communicates with the vegetable compartment cool air return port 37, and the lower end thereof is located at the lower portion of the cooling chamber 46. The refrigerator compartment / vegetable compartment communicates with the inside of the cooling compartment 46 at a cold air return port 72 which is open to the outside.

In this case, a concave portion 46A (see FIG. 6) projecting rightward is continuously formed in the cooling chamber 46 below the cooler 47.
The upper surface of the concave portion 46A is open in a state of being directed downward and forward (see FIG. 3).

On the other hand, the bottom wall of the heat-insulating box 6 has a rear portion that rises in a stepped manner, and a machine room 73 is formed outside the rear portion of the bottom wall. In the machine room 73, a compressor (not shown) and an evaporating dish condenser, which constitute a cooling device, are installed.

The operation and the cooling air circulation will be described with such a configuration.
When the compressor and the blower 48 are operated, the cooler 47 exerts a cooling action. The extremely low temperature (−25 ° C. to −30 ° C.) cool air cooled by the cooler 47 is sucked by the operation of the upper blower 48 and is blown out to the front distribution duct 56. The cold air blown out to the distribution duct 56 is discharged from the freezer compartment cool air discharge ports 57 and 58 and the freezer compartment duct 64 into the containers 53 and 54 in the freezer compartment 12 and the automatic ice maker 61, and is frozen at about -20 ° C. Cool to temperature.

Here, when the water supply pump 76 is operated,
From the water supply tank 74 in the refrigerator compartment 8 to the pipe 77 and the water supply pipe 8
Since the water is supplied to the automatic ice making machine 61 through 1,
Automatic ice making is performed. Then, the cool air in the freezing room 12 returns from the freezing room cool air return port 63 into the cooling room 46 on the suction side of the cooler 47 (indicated by an arrow in each figure).

The cool air blown out to the distribution duct 56 also flows from the cool air distribution port 66 to the communication duct 67 and the damper 6.
After flowing into the refrigerating room duct 24 through the upper portion 8 and ascending there, it is discharged into the refrigerating room 8 and the ice temperature room 19 from each of the refrigerating room cold air discharge ports 26,. reference). The damper 68 is controlled based on the temperature in the refrigerator compartment 8 to open and close the communication duct 67, whereby the refrigerator compartment 8 is kept at a refrigeration temperature of about + 5 ° C. and the ice compartment 19 is kept at 0 ° C.
The ice temperature is maintained at about -3 ° C.

A part of the cool air passing through the damper 68 (low-temperature cool air immediately after the heat exchange with the cooler 47) flows into the bypass duct 36 and directly flows into the upper part of the duct space 34.

On the other hand, the cool air circulating in the refrigerator compartment 8 and flowing down inside the door 21 flows from the cool compartment cool air return port 31 on the front lower side of the ice temperature container 16 to the space between the upper lid 32 and the partition member 7. Interval G
Flows into. Then, while moving forward, it flows down into the space in the vegetable compartment 11 around the lower vegetable container 43 along the slope of the lower surface of the pre-partition heat insulating member 29.

The cool air circulated in the ice room 19 and the rest of the cool air circulated in the cool room 8 flow into the upper part of the duct space 34 from the cool room return port 27 at the rear. It is mixed with the passing cold air.
After that, it flows into the rear part of the gap G from the communication hole 33, moves forward as described above, and mixes with the cool air from the cold room return port 31 on the way, along the slope of the lower surface of the pre-partition heat insulating member 29, and the lower vegetables. It flows down into the space in the vegetable compartment 11 around the container 43.

Thus, the inside of the vegetable container 43 is kept cool from the surroundings. Then, the cool air circulated in the vegetable room 11 is returned to the cool room / vegetable room cool air return duct 7 from the vegetable room cool air return port 37.
1 and flows down there to return to the cooling chamber 46 on the suction side of the cooler 47 from the cold room / vegetable room cold air return port 72 (see arrows in each figure).

At this time, the cold room / vegetable room cold air return port 72
Is open in a state of being directed downward and forward on the upper surface of the concave portion 46A formed to protrude rightward continuously from the cooling chamber 46 below the cooler 47, so that there is sufficient space between the concave portion 46A and the cooler 56. The distance is secured. Therefore, the humid cold air having a relatively high temperature flows from the cold room / vegetable room cold air return port 72 to the cooling room 4.
Even if the air is blown into the inside 6, frost hardly occurs around the return port 72.

Further, since local frost formation of the cooler 56 is hardly generated, deterioration of the cooling effect due to frost blockage is suppressed. Then, even when defrosting the cooler 47 by the defrost heater 49, dew water does not adhere to the return port 72, and the return port 72 is separated from the bottom surface of the cooling chamber 46 (including the concave portion 46A). There is no danger that defrost water dropped from the cooler 47 at the time of frost flows into the return port 72. This eliminates the need for a water seal around the cold air return port 72 for the refrigerator compartment / vegetable compartment and simplifies the structure.

In particular, since the bypass duct 36 for supplying a part of the cold air passing through the damper 68 to the vegetable compartment 11 directly without passing through the refrigerator compartment 8 or the ice compartment 19 is provided. From the refrigerator compartment 8 to the vegetable compartment 11
It becomes possible to supply fresh (low temperature) cold air that has not passed through.

As a result, low-temperature cold air is supplied to the vegetable compartment 11 in addition to the return cold air from the refrigerator compartment 8, so that the vegetable compartment 11 can be supplied regardless of the load on the refrigerator compartment 8 side.
Can be cooled stably.

The partitioning member 7 is composed of a partition plate 28 and a pre-partition heat insulating member 29 provided in front of the partition plate 28. The partition plate 28 is located below the front of the ice temperature container 16. Since the cold room return port 31 is formed and the lower surface of the pre-partition heat insulating member 29 is inclined forward and low, the return cold air from the refrigerator room 8 is transferred from the lower front part of the ice temperature container 16 to the partition member 7 and the upper lid. The water flows into the gap G between the two, and moves downward and flows down around the lower vegetable container 43 along the slope of the lower surface of the pre-partition heat insulating member 29.

The cool air circulated around the vegetable container 43 flows into the vegetable room cool air return port 37 in the upper part of the vegetable room 11 so that the cool air can be evenly and smoothly circulated around the vegetable container 43. Thus, the inside of the vegetable container 43 can be cooled well without unevenness. In particular, since the refrigerator compartment cold air return port 31 is located below the ice temperature container 16, it is difficult to see and the external appearance with the door 21 opened is not hindered.

Further, the cold air flowing out from another cold room return port 27 formed on the rear side of the ice temperature container 16 is mixed with the cold air passed through the bypass duct 36, and the partition member 7 and the upper lid 3 are mixed.
Since it flows into the rear part of the gap G between the two, it is possible to prevent the partition plate 28 of the partition member 7 or the vegetable compartment 11 of the upper lid 32 portion, which is directly hit by the cool air from the bypass duct 36, from being overcooled. . Thereby, while maintaining the cooling effect of the vegetable compartment 11, the necessity of attaching a heat insulating material to the partition plate 28 and the upper lid 32 and the occurrence of temperature unevenness in the vegetable compartment 11 can be more effectively eliminated. Become.

On the other hand, in the above, the water supply pipe 81 to the automatic ice making machine 61 receives the cooling action from the freezing room 12, but since the electric heater 82 is attached around the water supply pipe 81, the water inside is frozen. Nothing to do. In the event that foreign matter is clogged in the water supply pipe 81, the door 38 is first removed together with the vegetable container 43, and the upper end of the water supply pipe 81 is pulled out from the water supply joint 78 from the vegetable room 11 side. Next, the lower end of the water supply pipe 81 is pulled upward from the fitting hole 79, and the water supply pipe 81 is removed. Thereafter, when a new water supply pipe 81 is mounted, the new water supply pipe 81 is mounted in the same procedure as described above.
