Description

Refrigerator and evaporator for same

Technical Field

The invention relates to the field of household appliances, in particular to a refrigerator and an evaporator for the same.

Background

Generally, an air-cooled refrigerator controls the temperature in a refrigerator chamber by using forced circulation of cold air, and uses an evaporator to cool the refrigerator chamber, specifically, the evaporator is arranged in an interlayer between a freezing chamber and a refrigerating chamber or at the rear part of a refrigerator body. However, since a gap exists between the left and right end plates of the evaporator and the inner case of the refrigerator, a part of air passes through the gap, thereby reducing a cooling effect.

To solve the above problem, designers often provide two plastic or foam stoppers between the left and right end plates of the evaporator and the inner case of the refrigerator. The arrangement brings new technical problems, 1) during defrosting, the heat of the heating pipe at the bottom is not easy to conduct upwards, so that the frost or ice at the upper part cannot be completely melted, and the residual ice is larger and larger after a long time, which can hinder the normal operation of the fan and cause the refrigerator not to refrigerate; 2) in the defrosting process, the flow of defrosting water is blocked by the wind shielding structure in the process, the defrosting water is not easy to stay in the water drainage tank at the lower part, after the defrosting is finished and the refrigeration is recovered, the water turns into ice, and the ice is larger and larger along with the time lapse, so that the refrigeration of the refrigerator is poor or not.
