Abstract

The invention provides a return air duct which comprises a return air inlet, a first return air part, at least two branch return air parts and two return air outlets, wherein the return air inlet is positioned on a refrigeration box bladder; the top end of the first return air part is connected with the return air inlet; the at least two branch return air parts are respectively connected with the bottom end of the first return air part; and the two return air outlets correspond to the at least two branch return air parts and are spaced by a preset distance to ensure that an evaporator of a refrigerator uniformly frosts. Through the return air duct, return air can be guided to both sides of the refrigerator so as to ensure that the evaporator uniformly frosts, thereby the working efficiency of a frost melting heater is greatly improved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliance manufacturing, in particular to a return air duct and an air-cooled refrigerator with the return air duct. Background technique [0002] At present, the cooling methods of the refrigerator freezer mainly include two types: air cooling and direct cooling. The air-cooling method adopts the fan to supply air, which is beneficial to the uniformity of the temperature of the refrigerator, and the direct cooling speed is faster, so the use of air-cooled refrigerators is becoming more and more widespread. For air-cooled refrigerators, the design of the air duct has a great influence on its performance. At present, the return air duct of the air-cooled refrigerator is usually arranged on one side of the refrigerator, and blows the return air from the refrigerator to the bottom of the evaporator. [0003] The disadvantage of the prior art is that the water vapor brought by the return air will ...
