Embodiment Construction

[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0030] Such as image 3 As shown, the defrosting heater 40 of the refrigerator in this embodiment includes: an electric heater 42 that generates heat after being energized, an insulating tube 44 that is sleeved outside the heating wire, an outer tube 46 that is sleeved outside the insulating tube 44, and an outer tube 46 formed on the outer surface of the outer tube 46. Ceramic coating48.

[0031] The heating wire 42 generates heat after being energized, and radiates heat to the evaporator to remove frost on the surface of the evaporator. The insulating tube 44 is used to electrically isolate the heating wire 42 from the outside.

[0032] The outer tube 46 is a part that forms the appearance of the heater, and is made of a metal material with high rigidity and good thermal conductivity.

[0033] In this embodiment, the outer pipe 46 is an iro...

Abstract

A defrosting heater for electric refrigerator consists of electric heating-wires, insulating casings with outer casings and ceramic coatings. The outer casings are made of high strength thermal conductive metals. The ceramic coatings are of far-infrared materials, so that they work in high efficiency, when the heater works, with simple structure, low cost and good corrosion-proof performance.

Description

technical field [0001] The invention relates to a refrigerator component, in particular to a refrigerator defrosting heater. Background technique [0002] As we all know, a refrigerator is a household appliance that uses a refrigerant to evaporate in an evaporator to absorb the heat of the air inside the refrigerator, thereby keeping the freezer and refrigerator compartments of the refrigerator at a low temperature. The food stored in the freezer and refrigerated compartments of the refrigerator can be preserved for a long time in a frozen or refrigerated state, respectively. [0003] Such as figure 1 As shown, the evaporator 10 of a refrigerator generally includes: a refrigerant pipe 12 for cooling the surrounding air through which a refrigerant flows inside, and several heat exchange fins 14 vertically connected to the refrigerant pipe for heat exchange. [0004] The refrigerant pipes 12 are coiled several times in a serpentine shape to form a multi-layered transverse re...
