Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to an air duct structure and a refrigerator thereof. Background Art

[0002] The refrigerator air duct refers to the channel or path inside the refrigerator for the flow of cold air and hot air. The design of these channels plays a vital role in the refrigerator's temperature control, refrigeration efficiency, and food preservation.

[0003] In the prior art, the air inlet control of the refrigerator refrigeration duct is generally controlled by an electric damper, and the indoor temperature of the refrigerator compartment is monitored by a temperature sensor. When the temperature exceeds the set temperature, the temperature sensor will feed back a signal to the main board, and the main board will control the electric damper to open, and cold air will enter the cold storage compartment, thereby lowering the indoor temperature of the cold storage compartment; when the temperature of the cold storage compartment reaches the set temperature, the main board will control the electric damper to close, and cold air will no longer enter the cold storage compartment.

[0004] The electric damper of a traditional refrigerator is usually placed in the air duct foam and integrated with the air duct foam. During installation, firstly, the air duct foam, the electric damper and the air duct foam cover are prone to poor sealing and air leakage. Secondly, due to the large volume of the air duct, blind installation is adopted during production, which often leads to poor sealing and air leakage, uneven indoor temperature, especially the temperature at the bottom of the refrigerator is too low, making it difficult to preserve food.
