Refrigerator and moisture-preserving device

Abstract

The invention discloses a refrigerator and a moisture-preserving device thereof. The moisture-preserving device comprises a guide member, a plug block, a drive device, a cooling plate and an evaporating device, wherein the guide member is arranged on the upper part of a refrigerating chamber of the refrigerator and positioned in a foaming layer of a refrigerator body of the refrigerator, two ends of the guide member are respectively provided with an upper opening and a lower opening, the upper opening is communicated with an external environment, the lower opening is communicated with the inside of the refrigerating chamber so that the inside of the refrigerating chamber is communicated with the external environment through the guide member; the plug block is movably arranged in the guide member for opening and closing the guide member; the drive device is used for driving the plug block to move in the guide member; the cooling plate is arranged at the upper part of the upper opening and used for condensing moisture in the external environment into water and guiding the water into the guide member; and the evaporating device is arranged in the refrigerating chamber and positioned at the lower part of the lower opening and used for receiving water flowing out of the lower opening and evaporating the water into water vapor. The moisture-preserving device disclosed by the invention can effectively keep humidity in the refrigerating chamber.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator and a moisturizing device thereof. Background technique [0002] During the operation of the refrigerator, the air with high humidity inside the cabinet will condense into water when it encounters the evaporator, and will be discharged out of the cabinet along the drain pipe of the refrigerator, which will cause the relative humidity in the cabinet to become lower and lower. [0003] However, for the cold room, because most of the food stored in it is fresh, such as fruits and vegetables, the reduction of the humidity inside the cold room will directly cause the loss of water in foods such as these fruits and vegetables, which is not conducive to the preservation of food. Long-term preservation. Contents of the invention [0004] The present invention aims to solve at least one of the above-mentioned technical problems. [0005] Therefore, an object of th...
