Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, in particular to a fan for an air source heat pump. Background Art

[0002] An air source heat pump is a device that transfers low-temperature heat energy in the air to a high-temperature heat source. It is mainly composed of a compressor, a heat exchanger, an axial flow fan, an insulated water tank, a water pump, a liquid storage tank, a filter, a throttling device and an electronic automatic controller.

[0003] However, the common air source heat pumps on the market use simple filters or filter covers to filter debris in the incoming air. As the working time goes by, the filter screen or filter cover will accumulate more dust and debris, thereby increasing the resistance to air flow, and further requiring frequent manual cleaning. In summary, this affects the working efficiency of the air source heat pump.

[0004] Therefore, in order to solve the above problems, a fan for an air source heat pump is proposed. Utility Model Content

[0028] Reference Figure 2 , Figure 3 , Figure 4 The threaded hole 10 facilitates the cooperation with the threaded shaft 6 to achieve the purpose of lifting the brush 9. The structural design of the slider 11 and the limiting rod 12 realizes the function of limiting the brush 9, thereby ensuring that the brush 9 is in a vertical lifting state during cleaning, so that the bristles can directly and evenly contact the surface of the filter screen 15, ensuring the cleaning effect of the brush 9.

[0029] A slot 13 is provided in the middle of the top of the assembly box 3 , and a frame 14 is movably installed inside the slot 13 .

[0030] Reference Figure 1 and Figure 3 The card slot 13 facilitates the positioning of the frame 14, and at the same time, the user can quickly replace the filter 15, which reduces the replacement steps and thus reduces the downtime of the air source heat pump.

[0031] A filter screen 15 is fixedly installed inside the frame 14 , and a handle 16 is fixedly installed on the top of the frame 14 .

[0032] Reference Figure 1 The filter 15 is used to filter dust and impurities in the intake air, preventing impurities from entering the air source heat pump system and causing damage to the device.

[0033] A material collecting box 17 is fixedly mounted on the bottom of the assembly box 3 , and a through hole 18 is opened on the back of the assembly box 3 .

[0039] Working principle: When using this device, insert the frame 14 through the card slot 13, and accelerate the external air to enter the air source heat pump through the air intake fan 21. When the gas passes through the assembly box 3, it is filtered by the filter 15, and the filtered impurities fall into the collection box 17. Some impurities adhere to the surface of the filter 15, and the threaded shaft 6 is driven to rotate by the micro motor 5. The lifting block 7 is driven to rise and fall through the threaded shaft 6 and the threaded hole 10. The brush 9 is driven to move up and down by the lifting block 7. The slider 11 cooperates with the limit rod 12 to ensure the vertical lifting of the positioning plate 8. The surface of the filter 15 is cleaned by the brush 9. The cleaned impurities fall into the collection box 17 under the drive of their own weight and the brush 9, and the filtered gas enters the air source heat pump through the intake pipe 2.
