Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2022/001286
Kind Code:
A1
Abstract:
A refrigerator, comprising a box body; a refrigerated compartment for storing items, an evaporator compartment for accommodating an evaporator, and a return air duct connecting the evaporator compartment and the refrigerating compartment are defined in the box body. The return air duct is provided with a pre-condensing apparatus allowing air flow to pass through, enabling the return air flow to flow through the pre-condensing apparatus and then return to the evaporator compartment, the pre-condensing apparatus being provided with a temperature acquisition apparatus used for detecting the temperature of the pre-condensing apparatus. The box body also defines an air guide channel used for guiding some of the cooling air flow having undergone heat exchange by the evaporator to the pre-condensing apparatus, in order to reduce the temperature of the pre-condensing apparatus; an electronic control damper is disposed in the air guide channel, the electronic control damper being set up to be controlled to adjust the amount of cooling air flow flowing through the air guide channel to the pre-condensing apparatus on the basis of the temperature of the pre-condensing apparatus, in order to keep the temperature of the pre-condensing apparatus above zero degrees, so that when the return air flow flows through the pre-condensing apparatus, the moisture in the return air flow condenses into condensate on the pre-condensing apparatus.
