The method for controlling a refrigerator according to claim 7, wherein the condition for the functional compartment to issue the humidification request is specifically: when the current humidity of the functional area bin is smaller than the minimum value of the set humidity range of the functional area bin.
11. The method as claimed in claim 7, wherein the step of humidifying the functional compartment comprises the steps of: and opening the air supply air door and the second circulating fan, judging whether the current humidity of the functional zone bin is within a set humidity range, if so, closing the air supply air door and the second circulating fan, and if not, continuing to keep opening the air supply air door and the second circulating fan to humidify the functional zone bin.
12. The method as claimed in claim 11, wherein in the process of opening the supply air door and the second circulation fan to humidify the functional compartment, it is determined whether the current pressure of the functional compartment is greater than or equal to the critical pressure value of the functional compartment, if yes, the return air door is opened to supply air in a circulation manner, and if no, the return air door is controlled to be closed or kept in a closed state.
