With the development of society, air source heat pump water heaters have been put into use in large quantities. Existing equipment needs to be connected to a water tank through a water pipe when in use. Due to the lack of effective filtration of the water in the water pipe, and because the existing connections are often welded one-piece connections, it is more cumbersome to disassemble, clean or repair when blockage occurs, which greatly reduces the heating capacity of the air source heat pump water heater. Utility Model Content

There is no need to frequently disassemble the connecting pipe between the air source heat pump assembly and the water tank, which ensures that the heating capacity of the air source heat pump water heater is good and the operation is more convenient.

[0004] In order to solve the above technical problems, the utility model provides an air-energy heat pump water heater, comprising a bottom plate, an air-energy heat pump assembly is arranged on one side of the bottom plate, a water tank connected to the air-energy heat pump assembly is arranged on the other side of the bottom plate, a water outlet of the air-energy heat pump assembly is connected with a water outlet pipe, a water inlet pipe is arranged at the water inlet of the water tank, flanges are arranged at the ends of the water outlet pipe and the water inlet pipe, the two flanges are detachably sealed and connected together, a filter mechanism for filtering water entering the water tank is arranged on the flange of the water outlet pipe, the filter mechanism comprises a filter assembly and a cleaning assembly, and the filter assembly comprises a filter assembly arranged at the bottom of the water outlet pipe. The installation groove on the flange of the water outlet pipe is provided with a height-adjustable filter disc inside the installation groove for filtering water in the pipe, and a filter plate is provided on the outside of the filter disc and in the installation groove, and the cleaning component is provided at the lower part of the filter plate. The utility model can realize efficient filtering of water by arranging a filter mechanism between the connecting pipe between the air-energy heat pump assembly and the water tank, and clean the clogged filter component through the cleaning component in the filter mechanism, without the need to frequently disassemble the connecting pipe between the air-energy heat pump assembly and the water tank, thereby ensuring that the heating capacity of the air source heat pump water heater is good and the operation is more convenient.

[0005] The cleaning assembly comprises a plurality of cleaning brush rods arranged at the lower part of the filter plate, the cleaning brush rods are made of elastic steel wire or rubber material, an elastic water filter disc fitted with the filter disc is arranged on the filter plate, the filter holes on the elastic water filter disc correspond to the filter holes on the filter disc one by one, the circle where the outermost filter holes on the filter disc are located is located on the inner side of the water inlet pipe, and the remaining parts are solid flat plates, so that it can be ensured that when the filter disc moves downward to the cleaning brush rod to dredge the blocked water filter holes, the solid flat plate part of the filter disc can conflict with the lower part of the elastic water filter disc to avoid affecting the reset operation of the filter disc after subsequent cleaning, and the elastic water filter disc should be made of rubber material with good recovery elasticity and sealing performance. The utility model can use the recovery elasticity of the elastic water filter disc itself to ensure that the elastic water filter disc seals the water outlet pipe under the action of its own recovery elasticity when the cleaning brush rod dredges and cleans the impurities blocked in the water filter holes on the filter disc moving downward, so that the water in the water outlet pipe can only be discharged after being filtered along the filter holes of the elastic water filter disc, which is more convenient.

In addition, the circle where the outermost water filter holes on the filter plate are located is located on the inner side of the water inlet pipe, and the remaining parts are solid flat plates. When the dredging rod dredges the water filter holes on the filter plate, the solid flat plate part of the filter plate can conflict with the lower part of the elastic water filter plate.

[0007] A through hole matching the output rod of the telescopic push rod is opened on the upper part of the flange of the water outlet pipe. A sealing ring sleeve is arranged in the through hole. The sealing ring sleeve is bonded in the through hole by sealant.
