Air duct assembly of refrigerator and refrigerator

Abstract

The invention relates to the technical field of refrigeration equipment, in particular to an air duct assembly of a refrigerator and the refrigerator. The air duct assembly comprises a refrigeration chamber, a freezing air entering duct, a refrigerating air entering duct, freezing air returning ducts and a refrigerating air returning duct, wherein an evaporator is arranged in the refrigeration chamber, the refrigeration chamber communicates with the freezing air entering duct, the refrigerating air entering duct, the freezing air returning ducts and the refrigerating air returning duct, the communication port of the refrigeration chamber and the refrigerating air entering duct is a refrigerating air inlet, the evaporator is fixed on the inner wall of the refrigeration chamber and covers the refrigerating air inlet, freezing fans are arranged in the refrigerating air entering duct, and refrigerating fans are arranged in the refrigerating air entering duct. The air duct assembly has the beneficial effects that the refrigerating and the freezing can be independently closed, the refrigeration efficiency is improved, the control is convenient, and the defects that in the prior art, the temperature lowering speed of an air-cooled freezing and refrigerating box is slow, the refrigerating and the freezing cannot be closed independently, and the fresh keeping is poor are overcome.

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
