Description

Technical Field

[0001] The utility model relates to the field of air source heat pumps, in particular to a protective structure used for defrosting air source heat pumps. Background Art

[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source air to a high-level heat source. It can continuously absorb heat from a low-temperature source and output it to the heated water, directly reaching a predetermined temperature. Its efficiency is proportional to the heat exchange efficiency of the evaporator. However, existing air source heat pumps are basically installed outdoors without protection. The air source heat pump allows dust, foreign matter, rain, snow and frost to cover the top of the air source heat pump, affecting its heat exchange efficiency. Long-term erosion such as snow and frost will also affect the service life of the equipment. Utility Model Content

[0003] In view of the deficiencies of the prior art, the purpose of the present utility model is to provide a protective structure for defrosting an air source heat pump, which is intended to solve the technical problem that there is no protective structure on the outside of the air source heat pump in the prior art and the covered snow and frost cannot be cleaned and removed.

[0005] Preferably, an air source heat pump protection box is installed on the outside of the air source heat pump; the air source heat pump protection box adopts a full-inclusive type, with only an air inlet on the side for the air source heat pump and an air outlet on the top for the air source heat pump exhaust, and protective nets are provided on the inside of the air inlet and the air outlet to prevent snow, frost, dust and debris from entering the air source heat pump protection box, providing all-round protection for the air source heat pump. The movable component on the outside of the air source heat pump is installed with a predetermined program to drive the first defrost component and the second defrost component to perform reciprocating translational motion. When the first defrost component is translated forward, the snow in the top of the air source heat pump protection box can be cleared. When the first defrost component is translated backward, the frost in the top of the air source heat pump protection box can be shoveled off. At the same time, when the second defrost component at the lower end is translated forward, the side wall of the air source heat pump protection box can be intermittently knocked to knock down the frost and debris attached to the outside of the air source heat pump protection box, so as to avoid the outside of the air source heat pump protection box being covered for a long time.

[0006] Preferably, the moving assembly includes a driving threaded rod, a threaded sleeve, a limiting sliding rod, a limiting sliding sleeve and a frame; the driving threaded rod is transmission-connected to the outer side with a threaded sleeve; the driving threaded rod drives the outer threaded sleeve to perform reciprocating translational motion.

[0008] Preferably, the first defrost assembly includes a rotating motor, a mounting frame, a cleaning brush and a snow removal shovel; the mounting frame is installed on the right end of the rotating motor output shaft; when the first defrost assembly translates forward, the rotating motor controls the mounting frame to rotate, and the cleaning brush of the mounting frame faces downward, so as to clean the snow inside the top of the air source heat pump protection box.

[0009] Preferably, a cleaning brush is fixedly connected to the upper end of the installation frame; a snow removal shovel is fixedly connected to the lower end of the installation frame. When the first defrost assembly moves backward, the motor controls the installation frame to rotate.
