REFRIGERATOR

WIPO Patent Application WO/2021/258818

A1

A refrigerator, comprising a refrigerator body, wherein a refrigeration compartment for storing items, an evaporator chamber accommodating an evaporator, an air supply duct connected between the evaporator chamber and the refrigeration compartment, and a return air duct connected between the evaporator chamber and the refrigeration compartment are defined in the refrigerator body. The return air duct is provided with a pre-condensation device which allows an airflow to pass through, so that a return airflow flows through the pre-condensation device and then returns to the evaporator chamber. Also defined in the refrigerator body is an air guide channel which communicates with the air supply duct and the pre-condensation device. The air guide channel is configured to divert some of a cooling airflow within the air supply duct to the pre-condensation device so as to cool the pre-condensation device, so that moisture in the return airflow condenses on the pre-condensation device when the return airflow flows through the pre-condensation device. Hence, the purpose of effectively removing moisture inside same is achieved, evaporator frosting is reduced to a great extent or even avoided, and the refrigeration efficiency and the refrigeration effect of the evaporator are improved.
