Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular to an air duct assembly and a refrigerator. Background Art

[0002] The working principle of an air-cooled refrigerator is to use a built-in evaporator and fan to adjust the temperature inside the refrigerator. When the air in the refrigerator flows through the evaporator, heat exchange occurs between them because the air temperature is relatively high and the evaporator temperature is low. This process reduces the temperature of the air, and the cold air is then blown to the storage room in the refrigerator through the built-in fan, thereby realizing the refrigerator's refrigeration or freezing function.

[0003] In the related art, the evaporator, air duct, etc. are arranged at the back of the cabinet, so that the evaporator, air duct, etc. occupy the volume in the depth direction of the cabinet, resulting in a smaller depth of the storage room. With the application of refrigerators embedded in cabinets, the depth of refrigerator cabinets is getting shallower and shallower. The evaporator, air duct, etc. arranged at the back of the refrigerator occupy a larger space in the depth direction of the cabinet, making the depth of the refrigerator shallower, which seriously affects the volume of the refrigerator. In addition, the air supply distance in the air duct assembly is long, which is not conducive to air supply. Summary of the invention
