行えない問題があった。In a hotel, restaurant, or the like, it is necessary to temporarily store food prepared in a kitchen in a low-temperature storage until the food is provided to a customer. However, since the conventional low-temperature storage was opened only at the front as described above, it is necessary to take out and store the cooked food from the same direction,
There was a problem that it was not possible to smoothly provide the food to the customer and replenish the food to the storage room.

Since there is no back surface in the box, as shown in FIG.
A concave groove 104 extending up and down on both side surfaces 103B, 103B
The drain pipe 102 must be guided under the heat insulating box 103 through the inside of the concave groove 104. If the both sides of the low-temperature storage cannot be brought into close contact with the wall surface, a problem in appearance occurs. .

The front opening 7 is on the kitchen side and the rear opening 8 is on the customer side. When the compressor 36 and the blower 34 of the cooling device are operated, the cool air cooled by the evaporator 33 is sucked downward by the blower 34 and is blown downward from the outlet 42. The cool air blown out from the blowout port 42 flows into the cool air passage 39 on one side of the upper heat conduction box 21 as shown by the arrow in FIG. 2 and flows down there. And flows into the cool air passage 39 on one side of the lower heat conduction box 22 as it is, and the remainder flows into the cold air passage 39 between the upper and lower heat conduction boxes 21 and 22.

The heat flows into the cool air passage 39 on the other side of the heat conduction box 22. The cool air flowing into the cold air passage 39 on the other side of the lower heat conduction box 22 rises there and flows into the cold air passage 39 on the other side of the upper heat conduction box 21 from the through hole 14A. And the upper and lower heat conduction boxes 21, 2
The cold air that has passed through the cold air passage 39 between the two is joined in the cold air passage 39 on the other side of the upper heat conduction box 21, and the cool air above the upper heat conduction box 21 from the suction port 43. It flows into the passage 39.

却作用を受けるようになる。The cool air flowing into the cool air passage 39 above the upper heat guide box 21 flows from the other side of the upper heat guide box 21 to one side rear and rises in the cooling chamber 11 behind the evaporator 33. Then, it returns to the evaporator 33 from above the evaporator 33. By such a series of forced circulation of the cool air, the cool air from the evaporator 33 flows along substantially the entire upper, lower, left and right surfaces of the upper and lower heat conduction boxes 21 and 22. Therefore, the air in the upper and lower storage chambers 31 and 32 is cooled by the upper, lower, left and right walls of the upper and lower heat conduction boxes 21 and 22.

内の収容容積の縮小も発生しない。As described above, the defrost water from the evaporator 33 provided in the upper part of the heat insulating box 6 is discharged downward and outside the heat insulating box 6 by the drain pipe 72. Since it is inserted through the vertical partition member 13, it is not necessary to pass through the inside of the side wall of the heat insulating box 6 or the outer surface of the side wall as in the related art. Therefore, there is no danger that the appearance of the heat-insulating box 6 is impaired, the structure of the heat-insulating box 6 is simplified, and the upper and lower storage chambers 31 and 32 are formed by increasing the thickness of the side wall of the heat-insulating box 6.
There is no reduction in the storage volume inside.

Since the drains 56 and 57 are provided, the drain water flowing down the drain pipe 72 is supplied to the upper and lower storage chambers 31 and 32 or the cold air passage 3.
It is well insulated from the cold air in 9. Therefore, the drainage pipe 72
The re-freezing of the wastewater inside is also prevented.
