Technical Field
[0001] The invention belongs to the technical field of refrigerators, and in particular relates to a refrigerator air duct component based on air volume regulation. Background Art
[0002] At present, air-cooled refrigerators are favored by consumers because of their advantage of not requiring manual defrosting, and the home appliance industry has also expanded its product line of air-cooled refrigerators. There are mainly two ways to achieve the air volume adjustment function in air-cooled refrigerators in the prior art: one is to use a temperature sensor in conjunction with an electric damper to control the air volume of the compartment. The disadvantages of this method are high cost, many wiring harnesses, and low assembly efficiency; the other is to use a mechanical dial to manually adjust the air volume of the compartment. The disadvantage of this method is that during the air volume adjustment process, a large gap will be generated between the mechanical dial and the air duct, and the cold air will leak through the gap to the air duct mask, causing condensation or even frost on the surface of the air duct mask.
