[0002] Air source heat pump is an energy-saving device that uses high-level energy to transfer heat from low-level heat source air to high-level heat source. It mainly consists of two parts: air source heat pump circulation system and water storage tank. Air source heat pump water heater is a device that transfers heat from the air to water to produce hot water by consuming part of the electrical energy.

[0003] In the air source heat pump hot water unit, the water in the water storage tank flows through the condenser to complete the heating. Therefore, a filter component for filtering the water is generally provided at the water inlet end of the water storage tank to reduce the accumulation and precipitation of impurities in the water in the condenser, thereby improving the performance of the air source heat pump. However, the commonly used filter components currently need to be cleaned regularly during long-term use. During the cleaning process, the filter components need to be removed and installed, which is a cumbersome operation. At the same time, it will also cause a long downtime of the air source heat pump, affecting the normal supply of hot water. Utility Model Content

[0028] The bottom end of the flow guide cylinder body 7 is fixedly sleeved in the round hole 3.4, and the flow guide cylinder body 7 is rotationally sleeved and matched with the central cavity of the ring column cage body 5. A side opening 7.1 is provided on the side wall of the flow guide cylinder body 7 corresponding to the position of the connection cavity 3.3.

[0029] The ring column cage body 5 is rotationally sleeved in the first cylindrical cavity 3.1. A plurality of chambers are provided along the circumference on the periphery of the central cavity of the ring column cage body 5. Among them, the ring column cage body 5 includes an annular bottom plate 5.1 rotationally sleeved at a position near the bottom end of the flow guide cylinder body 7, a cylindrical cage 5.2 fixedly connected to the top surface of the annular bottom plate 5.1 at the bottom end and rotationally sleeved and matched with the flow guide cylinder body 7, a plurality of partition plates 5.5 fixedly arranged on the outer peripheral wall of the cylindrical cage 5.2 along the radial direction and evenly distributed along the circumference, and an arc-shaped frame 5.6 with both sides respectively connected to the outer ends of two adjacent partition plates 5.5. The cylindrical frame structure formed by the plurality of arc-shaped frames 5.6 is rotationally sleeved and matched with the first cylindrical cavity 3.1. The inner edge of the top end of the cylindrical cage 5.2 is fixedly connected with a round top plate 5.3, and a shaft sleeve 5.4 is fixedly sleeved at the center of the round top plate 5.3.

[0030] The filter element 6 is filled in the chambers on the outer edge of the ring column cage body 5, that is, the filter element 6 is respectively located in the areas between two adjacent partition plates 5.5. The distance between the outer ends of two adjacent partition plates 5.5 is not less than the width of the connection part between the first cylindrical cavity 3.1 and the connection cavity 3.3.

[0031] The top cover assembly 4 includes a cover plate 4.1 with the outer edge fixedly connected to the outer edge of the top end of the filter housing 3, a water inlet joint 4.2 sleeved at the bottom end of the cover plate 4.1 and facing the second cylindrical cavity 3.2, and a motor 4.3 fixed on the top surface of the cover plate 4.1 and used to drive the ring column cage body 5 to rotate. A fan-shaped hole 4.1.1 is provided on one side of the cover plate 4.1 away from the water inlet joint 4.2, and a fan-shaped sealing plate 4.4 is detachably installed at the fan-shaped hole 4.1.1.
