In one embodiment of the present invention, the control unit 22 is specifically configured to perform control according to different situations, and mainly includes three modes, namely a heat preservation mode, a storage mode and a moisture preservation storage mode:
in the heat preservation mode, when the second temperature is lower than the second preset temperature, the operating power of the semiconductor component 3 is increased, and the operating power of the refrigeration element is adjusted. In this mode, the semiconductor component 3 starts to operate, the hot end of the semiconductor component heats the food through the second radiator 6, the temperature is detected through the second temperature sensor 8, and the power of the semiconductor component 3 is continuously increased until the second preset temperature is reached.
