Description

Technical Field

[0001] The utility model relates to the field of air source heat pumps, and more specifically, to a rapid defrosting device for an air source heat pump. Background Art

[0002] Air source heat pump, as a kind of heat pump technology, has the reputation of "the carrier of nature's energy". It has multiple advantages such as low cost, easy operation, good heating effect, safety and cleanliness. It uses the energy in the air as the main power and drives the compressor through a small amount of electricity to achieve energy transfer. It does not require complex configuration and dedicated machine room. The evaporator of the air source heat pump will frost in winter because the outdoor temperature is lower than the indoor critical temperature. If it is not defrosted in time, the frost will accumulate more and more and seriously affect its normal work.

[0003] After searching, the existing patent (publication number: CN202021633199.9) discloses an air source heat pump rapid defrosting device, which is also an increasingly mature technology. It "includes a bearing base, a shell is fixedly installed on the upper surface of the bearing base, and an insulation cavity is provided on the inner wall of the shell. The insulation cavity is filled with glass rock wool insulation material, and a heating cavity is provided in the middle of the right side of the shell; a plurality of groups of evenly distributed electric heating wires are installed on the left side of the heating cavity, and a motor is fixedly installed in the middle of the right side of the inner wall of the heating cavity, and the output end of the motor is connected to the transmission rod. The utility model installs electric heating wires in the heating cavity, so that heating can be performed during defrosting. The motor drives the fan blades to rotate through the transmission rod to blow hot air into the shell, and the hot air can be evenly distributed into the shell through the ventilation plate at the connection between the heating cavity and the shell and the ventilation holes evenly distributed on the surface of the ventilation plate, and then through the heat-conducting fins, the shell is heated evenly, thereby improving the defrosting efficiency. The inventor found that the prior art has the following problems in the process of realizing the utility model:

[0004] Existing air source heat pumps use a heating fan to defrost during use, which takes a long time for heat conduction, has a complex structure, and consumes energy.
