Problems solved by technology

[0008] However, in the existing refrigerator, the evaporator 26 is arranged along the vertical direction, and the defrosting heater 29 is installed on the lower side, and it takes a lot of time to defrost the evaporator 26.
Frost forms on the surface of the evaporator most of the time, and the frost prevents direct contact between the air and the evaporator, and there is a problem of reduced heat exchange efficiency

Abstract

The present invention relates to a refrigerator with prefrosting function. It includes a box body, said box body at least has a cooling chamber, and the interior of said box body is equipped with a cooling air-circulating channel for cooling chamber, and the evaporator of cooling air is placed in the circulating channel. In order to inhibit frost formation of evaporator a prefrosting component formed by using metal component is placed in said refrigerator, said prefrosting component is mounted in the front of evaporator in the cooling air circulating process. Said invention can reduce frost formation of evaporator, the cooling air anjd evaporator can be mutually fully contacted, so that it can raise heat exchange efficiency, and also can prolong the defrosting cycle of evaporator.

Description

technical field [0001] The invention relates to the field of refrigerators. Background technique [0002] figure 1 It is a longitudinal sectional view of an existing refrigerator. As shown in the figure, there is a partition wall 12 formed in the horizontal direction in the middle of the refrigerator cabinet 11, and the cabinet body 11 of the refrigerator forms a freezer compartment 21 and a refrigerator compartment 41 respectively along the vertical direction with the partition wall 12 as the center, and the freezer compartment 21 and the refrigerator compartment The front opening of 41 has a freezer door 22 and a refrigerator door 42 combined by a hinge, and the freezer door 22 and the refrigerator door 42 rotate to open and close the freezer 21 and the refrigerator 41 of the casing 11 . [0003] A machine room 15 is formed in the rear space of the lower part of the box body 11 , and a compressor 16 capable of compressing refrigerant is arranged inside the machine room 1...
