と電気的に接続されている。Thus, between the top plate 4A of the heat conduction box 4 and the dew receiving plate 7,
An internal temperature display sensor 18 for detecting the temperature of the storage room 6 is provided. The sensor 18 uses, for example, a semiconductor temperature sensitive element such as a thermistor, and the outer surface of the sensor 18 is covered with a sensor holder 19 made of rubber or the like and fixed to the top plate 4A of the heat conducting box 4 via a clip 20. Has been done. The lead wire 18A extending from the sensor 18 is a digital display 22 which is inserted through the heat insulation box 1 and is arranged on the front grill 21 of the machine room.
Is electrically connected to.

冷却方式は、該貯蔵室６を高湿度に維持する１つの要件
として大きな効果を発揮する。In the above configuration, the cold air that has undergone heat exchange in the evaporator 11 is
The circulation operation in which the air is discharged from the blow-out port 8 to the cool air passage 5 by the blower 12 and the heat-conducting box 4 is cooled and then returned from the communication port 17 through the return passage 5B to the evaporator 11 again is repeated.
As a result, the air in the storage chamber 6 is indirectly cooled via the heat conducting box 4. Such an indirect cooling method of the storage chamber 6 exerts a great effect as one requirement for maintaining the storage chamber 6 at high humidity.

As a result, even if warm air enters the storage chamber 6 by opening the door 3,
The sensor 18 is hardly affected by this, and can prevent the instantaneous high temperature display of the display 22.

Although the temperature of the bottom of the storage room 6 becomes low, the display sensor 18
Detects the temperature of the cold air that accumulates between the top plate 4A of the heat conduction box 4 and the dew receiving plate 7 by the action of the dew receiving plate 7, and thus the temperature is substantially the same as the lowest temperature of the bottom of the storage chamber 6. Therefore, the temperature of the storage chamber 6 becomes extremely lower than the display, and the fear of freezing the stored food is eliminated.
