Refrigerator and evaporator for refrigerator

Abstract

The present invention discloses a refrigerator and an evaporator used in the refrigerator. The refrigerator includes a box body, a storage compartment defined by the box body, an evaporator compartment, an evaporator arranged in the evaporator compartment, An air intake duct that transmits cold air from the evaporator compartment to the storage compartment, and a return air duct that transmits heat from the storage compartment back to the evaporator compartment, wherein the evaporator There is a gap between it and the evaporator compartment, the gap is provided with a windshield, and the windshield is provided with a through hole. When the refrigerator is cooled, the return air flow transmitted from the storage compartment to the evaporator compartment Through the windshield, frost will quickly form to block the through hole, so that the windshield blocks the return air, so that the return air passes through the evaporator; when the refrigerator defrosts, the frost in the through hole melts and the defrost Water flows out through the through holes. The refrigerator provided by the invention has better cooling effect and longer service life.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a refrigerator and an evaporator used for the refrigerator. Background technique [0002] Usually, the air-cooled refrigerator adopts the forced circulation of cold air to control the temperature in the box, and uses the evaporator to cool down. Specifically, the evaporator is arranged in the interlayer between the freezing room and the refrigerating room or at the rear of the box. However, because there is a gap between the left and right end plates of the evaporator and the inner shell of the refrigerator, part of the air passes through the gap, thereby reducing the cooling effect. [0003] In order to solve the above problems, designers usually set two plastic stoppers or foam stoppers between the left and right end plates of the evaporator and the inner shell of the refrigerator. And such a setting has brought new technical problems, 1), when defrosting, the heat of the b...

AI Technical Summary

Problems solved by technology

And such a setting has brought new technical problems, 1) When defrosting, the heat of the bottom heating tube is not easy to conduct upwards, so that the frost or ice on the upper part cannot be completely melted, and the residual ice is getting bigger and bigger after a long time , will hinder the normal operation of the fan, resulting in no cooling of the refrigerator; 2) During the defrosting process, the defrosting water will be blocked by the windshield structure during the downward flow, and it will not be easily left in the lower drain tank. It turns into ice again, and as time goes by, the ice will grow larger and larger, resulting in poor or no refrigeration in the refrigerator
