Description

TECHNICAL FIELD

[0002] In the current situation of energy crisis and increasing environmental awareness, air energy heat pump units are widely used in the fields of heating, refrigeration and hot water supply due to their high efficiency, energy saving, environmental protection and pollution-free characteristics. Air energy heat pump units mainly absorb heat from the air through an evaporator, and then transfer the heat to the target medium after being compressed by a compressor to realize energy transfer and utilization.

[0003] A self-cleaning energy-saving air source heat pump unit is disclosed in Chinese patent application No. CN202311856194.0, which comprises a protective cabinet, a filtering assembly and a cleaning assembly. A limiting base is formed on the surface of the protective cabinet, and a discharge slot is formed in the limiting base at both ends. Two air inlet slots are arranged between the two discharge slots. The filtering assembly comprises a sliding plate seat, a receiving slot is formed in the center of the sliding plate seat, and a filter screen is assembled and connected in the sliding plate seat at both ends. An electric push rod is arranged on the inner side of the receiving slot, and a limiting cover is connected to the outer side of the limiting base.

[0004] Although the above-mentioned existing air energy heat pump unit can realize the processing operation of the air inlet dust of the air energy heat pump unit, in the actual use process, due to the fact that the air energy heat pump unit is not a complete closed shell, dust will inevitably enter the air energy heat pump unit, thereby reducing the use effect of the air energy heat pump unit. During the use of the air energy heat pump unit, a large amount of dust will be collected on the evaporator due to the negative pressure suction force and adhere to the evaporator. At this time, the dust is easy to block the spacing between two adjacent heat dissipation fins, thereby reducing the use effect of the air energy heat pump unit, and even stopping the machine for dust removal and maintenance operation, which is not conducive to the normal use of the air energy heat pump unit.

[0024] The application has at least the following beneficial effects:

[0025] 1. This invention uses an annular plate to drive the circular tube and the movable shell to rotate together. The rotation of the movable shell causes the cleaning brush to rotate, at which time the bristles of the cleaning brush can extend into the gap between two adjacent heat dissipation fins on the evaporator, realizing the cleaning operation between the two adjacent heat dissipation fins. This avoids dust accumulation between the two adjacent heat dissipation fins and prevents dust blockage, thus improving the dust cleaning operation of the evaporator. Moreover, the air source heat pump unit does not need to be stopped during the dust cleaning operation, improving the performance.

[0070] The application also provides a use method of the air energy heat pump unit, which is based on the air energy heat pump unit and includes the following steps.

[0071] S1: when the air energy heat pump unit is normally operated and only dust cleaning operation is needed, only the electromagnet 23 on the side close to the evaporator 3 is energized to start, so that the electromagnet 23 attracts the iron plate 22; at this time, one end of the positioning rod 21 is inserted into the positioning groove 24 on the side wall of the annular plate 10 to realize the fixing operation between the circular tube 8 and the annular plate 10; the annular plate 10 is fixedly connected with the movable shell 12, so that the locking operation between the circular tube 8 and the movable shell 12 can be realized.
