Refrigerator air duct assembly based on air volume adjustment

Abstract

The invention discloses a refrigerator air duct assembly based on air volume adjustment, and relates to the technical field of refrigerators. The refrigerator air duct assembly based on air volume adjustment comprises a supporting mask and an air duct plate arranged on the supporting mask. An air inlet channel is formed in the surface, away from the supporting mask, of the air duct plate; a supporting groove corresponding to the air inlet channel is formed in the surface, close to the supporting mask, of the air duct plate; the supporting groove communicates with the air inlet channel through a mounting groove; an accommodating cavity is formed between the mounting groove and the supporting groove; a guide piece is arranged in the accommodating cavity; an air adjusting piece is arranged on the guide piece in a sliding manner; the guide piece comprises a first bearing plate fixedly arranged in the supporting groove; and a first guide cavity and a second guide cavity which adjacently communicates with the first guide cavity are arranged on one surface of the first bearing plate side by side. The refrigerator air duct assembly based on air volume adjustment provided by the invention is reasonable in structural design and convenient to install, the adjusting effect on the air outlet amount of a refrigerator air duct is effectively improved, and a high market application value is achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a refrigerator air duct assembly based on air volume adjustment. Background technique [0002] At present, air-cooled refrigerators are favored by consumers because they do not require manual defrosting, and the home appliance industry has also expanded the product line of air-cooled refrigerators. The air-cooled refrigerators in the prior art mainly have the following two ways to realize the air volume adjustment function: one is to use a temperature sensor and an electric damper to control the air volume of the compartment. The disadvantages of this method are high cost, many wiring harnesses, and assembly efficiency. Low; the second is to use the mechanical dial to manually adjust the air volume of the compartment. The disadvantage of this method is that during the air volume adjustment process, there will be a large gap between the mechanical dial and the air duct, and ...

The air-cooled refrigerators in the prior art mainly have the following two ways to realize the air volume adjustment function: one is to use a temperature sensor and an electric damper to control the air volume of the compartment. The disadvantages of this method are high cost, many wiring harnesses, and assembly efficiency. Low; the second is to use the mechanical dial to manually adjust the air volume of the compartment. The disadvantage of this method is that during the air volume adjustment process, there will be a large gap between the mechanical dial and the air duct, and the cold air will leak into the air duct through the gap. On the mask, causing condensation or even frost on the surface of the air duct mask
