Specifically, in a preset time period, for example, 1 hour, 1 day, 1 week, etc., if it is detected that the fluctuation range of the chassis temperature is greater than the preset value, it indicates that the temperature fluctuation of the chassis 1 is large, and the temperature adjustment power of the microwave heating device 3 to the chassis 1 is too low, so that the operating power of the microwave heating device 3 needs to be increased by the controller, the heating temperature to the chassis 1 needs to be increased, the fluctuation range of the chassis temperature is within the preset range, and the chassis is guaranteed to be stably and continuously iced.
