A refrigerator air duct assembly and a refrigerator

Abstract

The present invention relates to the technical field of refrigeration equipment, in particular to a refrigerator air duct assembly and a refrigerator, including a refrigeration chamber, a freezing air inlet air duct, a refrigeration air intake air duct, a freezing return air duct, and a refrigeration return air duct. There is an evaporator in the room, and the refrigeration chamber communicates with the refrigerating air inlet duct, the refrigerating air inlet air duct, the refrigerating return air duct and the refrigerating return air duct respectively. The communication port of the refrigerating air inlet is a refrigerating air inlet, the evaporator is fixed on the inner wall of the refrigerating chamber and covers the refrigerating air inlet, and a refrigerating fan is arranged in the refrigerating air inlet. A refrigerating fan is arranged in the refrigerating air inlet duct. The beneficial effects of the present invention are: the present invention can separately close the refrigeration of refrigeration and freezing, improve the refrigeration efficiency, facilitate the control, and solve the shortcomings of the air-cooled refrigerator-freezer in the prior art, such as slow cooling of the air-cooled refrigerator-freezer, inability to independently close the refrigerator and freezer, and poor freshness preservation.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator air duct assembly and a refrigerator. Background technique [0002] At present, the air ducts of the single-system refrigerator-freezer air-cooled refrigerators on the market generally use a single fan structure, and some use a horizontally arranged double fan structure. The above structures have the following disadvantages: Single fan structure: the fan is fixed in the freezer air duct and simultaneously Supply air to the refrigerator and freezer to cool down the refrigerator and freezer compartment. The air supply to the refrigerator and freezer cannot be controlled independently, which has the disadvantage of slow cooling and poor freshness preservation; double fan structure: the horizontally arranged double fan structure has the problem that the left and right fans are easy to cross air, causing the heat exchanger Insufficient heat transfer effi...

AI Technical Summary

Problems solved by technology

[0005] The beneficial effects of the present invention are: in the present invention, the freezing air inlet duct and the freezing return air duct form a circulation air duct, the refrigeration air intake duct and the refrigeration return air duct form the first circulation air duct, and A refrigerating fan is installed in the air duct, and a refrigerating fan is installed in the refrigerating air inlet duct to realize the separate cooling of refrigerator refrigerating and freezing. Disadvantages of slow cooling of the freezer, refrigerating and freezing cannot be closed independently, and poor freshness preservation
