Embodiment Construction

[0010] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0011] figure 2 It is a structural schematic diagram of the damper for a refrigerator in the present invention. As shown in the figure, the damper for a refrigerator of the present invention is similar to the existing damper structure, including a damper 1, a rotating shaft 2 and a damper connecting plate 3, and the damper connecting plate 3 and the damper 1 are connected through the rotating shaft 2, A waterproof membrane 4 is pasted on the back side of the damper 1 . The waterproof membrane 4 is mainly used to prevent the formation of frost.

[0012] The waterproof membrane 4 can be made of antifreeze cotton and other materials, as long as it can play a waterproof effect, it can be used.

[0013] The present invention can prevent the water vapor generated during use from staying on the surface of the damper by pasting the waterproof...

Abstract

The invention relates to an air door for a refrigerator. The air door comprises a rotating shaft, an air door connecting plate and an air door. The air door is characterized in that a waterproof film is pasted at the back side of the air door, and the waterproof film is made of anti-freeze cotton. In the invention, the waterproof film is pasted at the back side of the air door, thus steam generated in the using process cannot remain on the surface of the air door, and frosting cannot be generated on the back side of the air door and water residues are difficult to generate, thereby the problem of frosting is solved, the normal opening, closing and using of the refrigerator air door are guaranteed, and the control precision of the refrigerator is improved.

Description

technical field [0001] The invention relates to a household electrical appliance component, in particular to a damper for a refrigerator, and belongs to the field of automatic controllers for household appliances and similar applications. Background technique [0002] Current refrigerators are usually divided into two regions, the freezer and the refrigerator, which are separated from each other by a partition. An evaporator and a fan chamber communicated with the evaporator are arranged in the rear wall of the refrigerator. There is an air outlet duct connected to the fan room between the compartments. The air outlet duct is divided into the compartments of the refrigerator and communicated with the freezer and refrigerator respectively. The fan passes the cold air cooled by the evaporator through the outlet air. Blow directly into the refrigerator and freezer. In order to control the refrigeration of the refrigerator compartment and the freezer compartment, a damper is ar...
