Abstract

The invention discloses a defrosting device of an air conditioner evaporator. The defrosting device comprises an air conditioner hanging machine body and an outer machine body, a device cavity is formed in one side of an air outlet of the air conditioner hanging machine body, a rotating rod is rotationally connected to the inner wall of the device cavity, one end of the rotating rod extends into the air outlet and is fixedly connected with a wind wheel, a cam is fixed on the rotating rod, a cavity is formed above the device cavity, an abutting rod penetrates through the cavity and the device cavity in a penetrating manner, the lower end of the abutting rod abuts against the cam through a rolling wheel, a piston is arranged at the upper end of the abutting rod, the piston is elastically connected with the inner top of the cavity through a spring, an air pipe is connected to the inner wall of the cavity, and an evaporator is arranged in the outer machine body. The air conditioner is reasonable in structure, when the air conditioner works, all the evaporation iron sheets of the evaporator can be continuously impacted, so that frost on the surface of the evaporator can be effectively shocked, so that the shutdown time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a defrosting device for an air conditioner evaporator. Background technique [0002] At present, the air conditioner has become more and more popular. The air conditioner mainly consists of an on-hook unit and a base unit. The on-hook unit is installed indoors, and the base unit is installed outdoors. When the air conditioner is used for heating in winter, the gas Freon is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (in this case, the condenser), condenses and liquefies heat, and becomes a liquid, and at the same time heats the indoor air. So as to achieve the purpose of increasing the indoor temperature. The liquid freon is decompressed by the throttling device and enters the heat exchanger of the outdoor unit (the evaporator at this time), where it evaporates and absorbs heat to b...
