When the refrigerating compartment temperature t1, the ice making compartment temperature t2 and the freezing compartment temperature t3 are detected, real-time detection or timing detection may be employed.

The second predetermined temperature is higher than the third predetermined temperature. Preferably, the third preset temperature may be set to 3 ℃.
Specifically, when the temperature of the refrigerating chamber is greater than or equal to a third preset temperature and the opening and closing state is on, the electric heating on-off rate is set to be a first on-off rate n 1; when the refrigerating chamber temperature t1 is greater than or equal to a third preset temperature and the opening and closing state is closed, setting the electric heating on-off rate as a second on-off rate n 2; the first on-off ratio n1 is higher than the second on-off ratio n 2. Preferably, the first on-off ratio n1 is 40%; the second on-off ratio n2 is 30%. When the temperature t1 of the refrigerating chamber is lower than the third preset temperature and the opening and closing state is on, setting the on-off rate of electric heating as a fourth on-off rate n 4; when the temperature t1 of the refrigerating chamber is lower than a third preset temperature and the opening and closing state is closed, setting the electric heating on-off rate as a third on-off rate n 3; the fourth on-off ratio n4 is higher than the third on-off ratio n3, and the second on-off ratio n2 is lower than the third on-off ratio n 3. Preferably: the third on-off ratio n3 is 50%; the fourth on-off ratio n4 is 60%.
