When the air supply device 70 and the second air door 82 are controlled according to the difference value between the first humidity value and the second humidity value, when the moisture permeation device 24 conducts moisture one-way permeation work, the humidity in the storage space is gradually reduced, the outside humidity is gradually increased, the difference value between the two is smaller and smaller, and when the difference value is smaller than or equal to a first preset value, the air supply device 70 is opened, the second air supply opening is opened, and the moisture permeation efficiency is improved. Further, humidity in the storing space reduces gradually once more, outside humidity reduces earlier under air supply arrangement 70's effect, later in the basis that reduces unchangeably, reduce or the rising rate reduces, finally make the difference between the inside and outside of storing space littleer and littleer, when the difference between humidity in the storing space and the humidity in the outside is less, can regard humidity in the storing space to become the step-down, satisfy the requirement, the difference between inside and outside is not enough to make and pass through moisture vapor device 24 work, air supply arrangement 70 stops the machine, the second supply-air outlet is closed, energy-conservation.

In some embodiments of the present invention, it should be noted that, for some reason, for example, when the humidity in the storage compartment is suddenly increased, the air supply device 70 may be in the closed state, if it is determined that the difference between the first humidity value and the second humidity value is smaller than the first preset value, or even smaller than the second preset value, the air supply device 70 is started first, the second air supply opening is opened, and after the air supply device 70 is started, the humidity outside the storage compartment is obviously decreased, so as to ensure the moisture permeation efficiency of the moisture permeation device 24.

In some optional embodiments of the present invention, in order to further improve the control accuracy and prevent the misoperation caused by the case that the humidity inside and outside the storage space is relatively large, when determining whether the difference between the first humidity value and the second humidity value is smaller than the second preset value, it is further determined whether the first humidity value is larger than the preset humidity value; when the difference between the first humidity value and the second humidity value is smaller than a second preset value, and the first humidity value is smaller than or equal to the preset humidity value, the air supply device 70 is closed, and the second air door 82 is controlled to close the second air supply opening.

In some embodiments of the present invention, in order to preferentially cool and prevent frosting of the rear wall of the storage device 20, the method for controlling the refrigerator, as shown in fig. 2, in which a dashed arrow in fig. 2 is a cooling process, a solid arrow is a process for improving the efficiency of the moisture permeable device 24, and before controlling the second damper 82 to open the second air supply opening, further includes: it is judged whether or not the refrigeration system of the refrigerator stops operating and whether or not the first damper 81 closes the air guide device 60. When the refrigeration system stops operating and the first damper 81 closes the air guide device 60, the second damper 82 is allowed to be controlled to open the second air supply port. If the cooling system is not stopped and the air guide device 60 is in the open state, cooling is performed at this time, and even if it is detected that the second air supply port needs to be opened to improve the efficiency of the moisture permeable device 24, the second air supply port is not opened and cooling is preferentially performed. The operation of the first damper 81 can be controlled according to the temperature in the storage compartment or the temperature in the storage space, and the temperature can be detected by the temperature sensor 73 provided in the storage device 20. In the process of improving the efficiency of the moisture permeation device 24, the cooling capacity of the evaporator 74 can be utilized, and the evaporator 74 can be defrosted, so that the overall efficiency of the refrigerator can be improved.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
