Since the cool air flows around the outer wall of the sub-storage chamber including the heat transfer panel, the sub-storage chamber is cooled via the heat transfer panel. The cooling temperature in the sub-storage room and the cooling temperature in the main storage room are managed in different temperature zones, and can be classified according to the type of food and stored in a refrigerator with an appropriate storage temperature to maintain good quality. The outside air that enters the sub-storage room does not circulate with the cold air, which prevents excessive frost formation on the evaporator and prevents cooling failure of the main storage room.

The drain water from is guided to the evaporation tray 62 arranged in the lower part of the storage main body 1 by the drain hose 60, heated and evaporated by the heater 64, and the exhaust hot air after passing through the condenser 53 is discharged into the duct 66 and the space of the cover 59. By forming the air passage through the passage 58 to the upper surface of the evaporation tray 62 to allow the air to flow, the evaporation of the drain water can be increased and the water can be effectively evaporated. There is no need for a drain tank and the work of draining the water in the tank as in the past, and there is no need for wastewater management.

る。As described above, according to the present invention, a closed cold air passage through which a part of the cold air from the main storage chamber passes and circulates around the sub-storage chamber provided separately from the main storage chamber, is provided. By cooling the outer wall plate of the sub-storage room made of a material with good conductivity,
The temperature of the sub storage chamber can be different from that of the main storage chamber.

効率良く副貯蔵室の冷却も行える。Since the cold air is not directly introduced into the sub-storage room, it is circulated without being affected by the outside air that enters the sub-storage room, and there is no excessive frost formation on the evaporator. While maintaining a high temperature, the single refrigeration cycle device can efficiently cool the sub-storage room.
