As a cooling means, a unit cover 9 having a blowout port 7 at an upper portion and a suction port 8 at a lower portion is disposed in a space between the unit cover 9 and the inside of the unit cover 9. And a blower 11 for circulating cool air, which faces the outlet 7. The evaporator 10 is connected by a refrigerant pipe 15 to an electric compressor 13 and a condenser 14 disposed in a machine room 12 defined on the outside of the main body 1. Reference numeral 16 denotes a guide plate that prevents a short cycle of cold air and actively guides the cool air to a space opposite to a space where the evaporator 10 is provided.

い。In the above configuration, the cool air that has undergone heat exchange in the evaporator 10 is discharged from the outlet 7 to the cooling passage 5 by the blower 11 to cool the heat conduction box 4. Thereby, the storage room 6
Is indirectly cooled through the heat conduction box 4. Such an indirect cooling method can maintain the storage room 6 at a high humidity, but on the other hand, the cooled air in the cooled storage room 6 has a temperature difference between the upper and lower sides of the storage room 6 because the cool air falls down by natural convection. In addition, it is difficult to maintain uniform freshness of stored products.

とになる。However, according to the present invention, the low-temperature cold air stagnating at the bottom of the storage room 6 is sucked from the suction port 18 by the operation of the blower 21 disposed in the storage room 6 as indicated by an arrow,
The discharged cool air is discharged obliquely upward from the outlet 19, and is circulated upward along the rear plate of the storage chamber 6 and mixed with the cool air in the upper part of the storage chamber 6. As a result, the temperature difference between the upper and lower sides of the storage room 6 is eliminated, and since the cool air is circulated at a slight wind speed, the storage room 6 can be maintained at a high humidity. To achieve uniform freshness.

The cooling means provided in the cooling passage 5 is not limited to the cooling means in the embodiment, and can be freely changed as long as it cools the storage room indirectly. Further, the present invention exerts the same effect not only in the horizontal cooling storage as in the embodiment but also in the vertical cooling storage.
