Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention, the refrigerator includes: a housing 10, a moisturizing device 20, and a controller 30.
The controller 30 is configured to:
acquiring food information stored in the humidity maintaining compartment in response to a humidity real-time adjusting operation of the refrigerator;
