Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration system control devices for refrigeration equipment, and in particular to an integrated refrigerator electric air door heating film with a 3D stereoscopic structure. Background Art

[0002] The electric damper is a controller used by air-cooled refrigerators to control the air volume and refrigeration efficiency. The purpose of controlling the refrigerator compartment temperature is achieved by controlling the air volume of the refrigerator through the damper. The common refrigerator dampers on the market generally include ventilation doors, air volume adjustment blades and motors. Since the damper is in the hot and cold control exchange channel, the condensation phenomenon generated in the refrigerator will have a greater impact on the damper. Therefore, some refrigerator dampers are also equipped with heating films to improve the working flexibility after frost condenses on the damper.

[0003] However, most of the existing heating films are flat. When in use, they are directly attached or hot-riveted to the damper to heat one surface of the damper. The heating area is too small, and the heating effect is insufficient when the heating requirement is relatively high.

[0004] Therefore, it is necessary to provide an integrated refrigerator electric damper heating film with a 3D structure to solve the above technical problems. Utility Model Content
