The application environment of the thermal fuse 4 is long exceeding the body temperature of the fuse 4, which may cause the fuse 4 to open or fail below the normal opening temperature. For a fuse 4 with a nominal fuse temperature of 72 c/73 c, which is commonly used, it is desirable that the temperature during application be lower than the bulk temperature (e.g., 50 c). Therefore, the temperature of the periphery of the fuse 4 is detected by the first temperature sensor 5, so that the working temperature of the fuse 4 can be judged, and further, when the temperature of the first temperature sensor 5 is higher than the body temperature in the defrosting process of the heater to the evaporator 2, the heater can be controlled to stop heating, so that the detection temperature of the first temperature sensor 5 is lower than a preset temperature value (such as 35 ℃), and then the heater is started to continue defrosting, so that the fuse 4 can work in an environment lower than the body temperature by 50 ℃ for a long time, the service performance of the fuse 4 is ensured, and the defrosting performance of the refrigerator evaporator 2 is effectively ensured.

Therefore, when the temperature of the evaporator 2 is higher than the preset temperature threshold, it indicates that the frost and ice on the surface of the evaporator 2 are already removed or most of them are removed, and the heater can be controlled by the second temperature sensor 6 to finish the defrosting process.
