According to the technical scheme, based on the fact that the refrigerating temperature of the refrigerating compartment 12 is controlled preferentially as a control standard, the temperature of the refrigerating compartment 12 can be effectively prevented from deviating from the refrigerating preset temperature, the cost increase caused by the fact that the second electric heating component is not needed to be arranged in the refrigerating compartment 12, meanwhile, the heating temperature in the heating compartment 11 is controlled based on the control of the refrigerating temperature of the refrigerating compartment 12, and therefore the heat preservation requirement of a user on food can be met as soon as possible.
