Abstract

The invention discloses a refrigerator air-cooling evaporator defrosting structure and a refrigerator. The refrigerator air-cooling evaporator defrosting structure comprises a fin evaporator and a heater, wherein the heater is positioned below the fin evaporator and is adjacent to the fin evaporator; the refrigerator air-cooling evaporator defrosting structure is characterized by further comprising a sealing thermal insulating box, wherein the sealing thermal insulating box is provided with a hollow cavity; an opening in one end of the hollow cavity is upwards; and the fin evaporator and the heater are accommodated in the hollow cavity. According to the refrigerator air-cooling evaporator defrosting structure, the fin evaporator and the heater are accommodated in the hollow cavity, heat generated by the heater is unlikely to lose and can be better used for defrosting the fin evaporator, so that the defrosting efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a defrosting structure of an air-cooled evaporator of a refrigerator and a refrigerator. Background technique [0002] Along with the development of science and technology, refrigerator is also just being one of electrical appliance necessary in people's life. In the existing air-cooled refrigerator, the defrosting structure mainly uses electric heating wires to conduct natural convection heat conduction through the aluminum plate or fins in contact with the finned evaporator to defrost. [0003] However, the existing defrosting structure still has the problem of low defrosting efficiency, which seriously affects the refrigeration efficiency and cooling effect of the refrigerator, and thus causes high energy consumption of the refrigerator. In the existing defrosting structure, since the finned evaporator is in a relatively open space, the heat generated by the heating wir...
