It is also an energy regeneration device with broad application prospects and significant advantages. It can be used for heating systems, domestic hot water, etc. With the continuous advancement of technology and the continuous promotion of its application, air source heat pumps will play an important role in more fields.

[0003] After searching, it was found that the publication number CN216814344U discloses a heating device for an air source heat pump, which includes a water tank. The top of the water tank is fixedly connected to a fixing frame by bolts. Although the above device can filter impurities in the heating water when in use, it is inconvenient to clean the filter after a long period of use. Therefore, an efficient and energy-saving air source heat pump heating device is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcoming in the prior art that it is inconvenient to clean the filter screen after the equipment is used for a long time, and to propose an efficient and energy-saving air source heat pump heating device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The top of the water tank is fixedly connected with a water supply pipe running through it. The bottom of the water supply pipe is provided with an arc groove used in conjunction with the blades. The circumference of the water supply pipe is installed with a solenoid valve that controls the connection of the water supply pipe. The top of the water tank is installed with a water level sensor.

[0008] As a further solution of the present invention, a medicine box and a medicine pump are fixedly connected to the top of the water tank, the liquid inlet of the medicine pump is connected to the medicine box, and the liquid outlet of the medicine pump is connected to the water tank and is located on one side of the blade.

[0012] As a further solution of the present invention, an overflow pipe is fixedly installed on the top of the water tank.

[0013] In this application, the return water pump extracts the hot water discharged by the air source heat pump and discharges it into the water tank. After passing through the filter, the hot water in the water tank is extracted for use through the water outlet pump. At the same time, the liquid level in the water tank is monitored by the water level sensor. When the liquid level in the water tank is low, the water supply pipe is opened by the solenoid valve to fill the water tank. During the water filling process, the medicine pump is started to inject the medicine in the medicine box into the water tank. During the water replenishment process, water is sprayed to the blades through the water supply pipe, and multiple blades are used to drive the rotating shaft to rotate. The rotating shaft drives the scraper to clean the filter, thereby avoiding clogging of the filter and improving the filtering effect of the filter. At the same time, when the blades rotate, they can also mix the medicine liquid with water. The cleaned impurities fall into the sewage pipe. The sewage valve in the sewage pipe is opened to discharge the impurities.
