Switch to operation. Then, according to a command from the controller 48, the evaporator fan 6n and the code heater 45 are turned on, and the heat insulation operation can be performed.

  During the heat insulation operation, the circulating air blown from the outlet 6j of the duct 40 on the ceiling flows to the left side through the upper surface of the stacked vegetable containers 41 in FIG. It flows downward through the outside and then flows to the right along the bottom plate 31. At this time, the circulating air is warmed by the cord heater 45, and the heated circulating air flows upward through the right outer side of the vegetable container 41 and returns to the cooling device 6 in the cooling stopped state from the suction port 6k of the duct 40. The same circulation is repeated by the rotation of the evaporator fan 6n, and the vegetable container 41 is kept warm.

  Further, in the cold insulation mode, the temperature is detected by the evaporator temperature sensor SE1 and the internal temperature sensor SE2 during operation, and when the detected internal temperature becomes, for example, “set temperature + α”, the compressor 6b, the condenser fan 6m, The evaporator fan 6n is activated to start the cooling operation, and when the detected internal temperature becomes, for example, “set temperature−α”, the driving of the compressor 6b and the condenser fan 6m is stopped to stop the cooling operation.

  In the heat retention mode, when the evaporator temperature sensor SE1 and the internal temperature sensor SE2 detect temperatures during operation, respectively, and the detected internal temperature becomes, for example, “set temperature + α”, the code heater 45 and the evaporator fan 6n. Is turned off to stop the heating operation, and when the detected internal temperature becomes, for example, “set temperature−α”, the code heater 45 and the evaporator fan 6n are turned on to start the heating operation.

  According to the above configuration, the vegetable container 41,... Is heated indirectly by heating the circulating wind with the cord heater 45 in the winter, so the vegetable container 41,. It can be kept warm while preventing drying.

Next, FIG. 25 will be described.
A filter 55 is detachably attached below the suction port 6k of the duct 40 in the cold air circulation path of the cool box 1, and the filter 55 is configured to remove dust from the circulating air.
