Technical Field

[0001] This utility model relates to the field of air source heat pumps, specifically an air source heat pump cleaning device. Background Technology

[0002] An air source heat pump is an energy-saving device that uses high-grade energy to move heat from a low-grade heat source, air, to a high-grade heat source. It is a type of heat pump. Like a pump, a heat pump can convert low-grade heat energy (such as the heat contained in air, soil, and water) that cannot be directly used into usable high-grade heat energy, thereby achieving the purpose of saving some high-grade energy (such as coal, gas, oil, and electricity).

[0003] In the prior art, when cleaning an air source heat pump, the filter is usually cleaned manually by holding the air intake. The long-term arm swinging during cleaning can cause arm pain, resulting in reduced cleaning efficiency and affecting the cleaning effect. In addition, the cleaning brush can easily push dust into the machine and cause blockage. Based on this, the present invention proposes an air source heat pump cleaning device. Utility Model Content
