[0002] The variable frequency air source heat pump is a highly efficient and energy-saving HVAC equipment. Its working principle is based on the heat pump cycle principle, and heating and cooling are achieved through the circulation of refrigerant.

In order to prevent the filter from being blocked, some existing variable frequency air source heat pumps are designed with a special cleaning mechanism and installed with a corresponding electric drive mechanism to drive its operation to prevent the filter from being blocked, thereby affecting its use.

The above technical solution reduces the energy consumed during the operation of the equipment.

[0036] See also Figures 1 to 6Furthermore, a hot exhaust gas recovery and utilization mechanism 2 is provided above the energy-saving cleaning mechanism, and the hot exhaust gas recovery and utilization mechanism 2 includes a U-shaped transmission pipe 201, an L-shaped transmission pipe 202, an externally threaded pipe 203, an annular groove 204, a water molecule adsorption cotton 205, an air filter plate 206, a dust filter plate 207 and an internally threaded connecting pipe 208. The U-shaped transmission pipe 201 is located in the middle position above the air outlet 3, the externally threaded pipe 203 is fixed to the lower end surface of the U-shaped transmission pipe 201, and the L-shaped transmission pipe 202 is located below the externally threaded pipe 203.

[0037] The annular groove 204 is located in the middle position of the upper end surface of the L-shaped transmission tube 202, and the dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205 are all located inside the annular groove 204; the wind source passing through the wind fan blades 8 will enter the interior of the U-shaped transmission tube 201, and enter the interior of the variable frequency air source heat pump 1 along the U-shaped transmission tube 201 and the L-shaped transmission tube 202, and in the process of circulating inside the L-shaped transmission tube 202, it will pass through the dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205, and the dust filter plate 207 and the air filter plate 206 can adsorb foreign matter in the hot air source, and the air filter plate 206 can absorb the water contained in the hot air source and dry it. Through the above technical solution, the discharged hot air source can be recycled to ensure that the equipment can still ensure its heating efficiency when the heat energy in the air is greatly reduced in extremely cold weather.

[0038] Furthermore, the hot waste gas recovery and utilization mechanism 2 also includes a fixed sleeve 209, the upper end surface of the fixed sleeve 209 is fixed to the lower end surface of the internal threaded connecting pipe 208, and the lower end surface of the fixed sleeve 209 is connected to the upper end surface of the dust filter plate 207; by fixing the fixed sleeve 209 on the lower end surface of the internal threaded connecting pipe 208, the stability of the dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205 can be ensured.

[0039] In actual application, the outer surface of the internal threaded connecting tube 208 is fixed with a plurality of rotating auxiliary handles; when the dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205 have been used for too long, the internal threaded connecting tube 208 is manually rotated by rotating the auxiliary handle, and the external thread of the external threaded tube 203 is transmitted, so that the rotating internal threaded connecting tube 208 can move up and down. At this time, the internal threaded connecting tube 208 is moved upward, and as the internal threaded connecting tube 208 moves, a gap is generated between the lower end surface of the internal threaded connecting tube 208 and the L-shaped transmission tube 202. When the gap is large enough to take out the dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205, the internal threaded connecting tube 208 can be rotated manually by rotating the auxiliary handle. 5, stop rotating the internal thread connecting tube 208, take out the dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205 from the inside of the annular groove 204, and put the new dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205 into the inside of the annular groove 204, and then rotate the internal thread connecting tube 208 in the opposite direction until the lower end surface of the fixing sleeve 209 contacts the dust filter plate 207 again. When the dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205 are replaced, the dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205 taken out from the inside of the annular groove 204 are washed and dried.

A metal rod 217 is provided on both sides of the inner wall of the sealing ring 212. The outer surface of the metal rod 217 is provided with a spring 219. The lower end surface of the spring 219 is connected to a metal sleeve 218 that is movably sleeved on the outer surface of the metal rod 217, and the metal sleeve 218 is fixed to the sealing ring 212 with its surface facing the sealing ring 212; when the internal thread connecting tube 208 is moved downward, the fixed sleeve When 209 has not yet entered the interior of the L-shaped transmission tube 202, the sealing ring 212 will first enter the interior of the annular sealing groove 211. As the internal threaded connecting tube 208 descends, the lower end face of the sealing ring 212 will contact the inner wall of the annular sealing groove 211. When the lower end face of the sealing ring 212 contacts the inner wall of the annular sealing groove 211, but the internal threaded connecting tube 208 continues to move downward, the sealing ring 212 and the metal sleeve 218 fixed thereto will stop in place, and the metal sleeve 218 will then squeeze the spring 219.

[0041] An annular sealing groove 211 is provided on the outside of the bottom end of the sealing ring 212 and is located on the outside of the upper end face of the L-shaped transmission tube 202.

An annular groove 213 is provided at the position corresponding to the inner wall of the sealing ring 212 and the fixing rod 216, and the top end of the fixing rod 216 is inserted into the inner part of the annular groove 213; when the fixing sleeve 209 enters the interior of the L-shaped transmission tube 202, the two sides of its lower end surface will contact the two rectangular push heads 214 respectively and push the rectangular push heads 214 outward. The moving rectangular push head 214 of 214 will squeeze the return spring 215, and the fixing rod 216 fixed to the outer surface of the rectangular push head 214 will be inserted into the inner annular groove 213 located on the outer surface of the sealing ring 212, so as to fix the sealing ring 212 there. By fixing the sealing ring 212 there, it is possible to prevent the wind source in contact with the dust filter plate 207, the air filter plate 206 and the water molecule adsorption cotton 205 from generating repulsive force, thereby causing the gap between the internal threaded connecting pipe 208 and the L-shaped transmission pipe 202 to become larger, and the wind source leaking from this gap;

[0043] When the internal threaded connecting tube 208 is actively moved upward, as the fixing sleeve 209 fixed to the lower end surface of the internal threaded connecting tube 208 rises, the fixing rod 216 fixed to the rectangular pushing head 214 can be gradually pushed outward through the reaction force of the squeezed return spring 215, thereby releasing the fixation of the sealing ring 212.
