Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, in particular to an air source heat pump cold and hot water heater. Background Art

[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It is a form of heat pump. As the name suggests, a heat pump is like a pump, which can convert low-level heat energy that cannot be directly used into high-level heat energy that can be used, thereby achieving the purpose of saving some high-level energy. Air source heat pumps are often installed inside water heaters, and the air source heat pump can heat the liquid inside the water heater.

[0003] Among the publicly authorized patents, in the Chinese patent with patent number "CN202111307161.1", an air source heat pump unit is disclosed; a platform is provided at the rear of the shell; the heat pump body includes an evaporator and an insulated water tank, the evaporator is arranged in the accommodating cavity on the side of the second window, and the insulated water tank is arranged on the platform; the protective net is arranged on the second window, and the protective net is provided with air holes for letting in air; the cleaning mechanism is arranged between the protective net and the evaporator to clean the dust on the protective net and the evaporator; the lifting mechanism is arranged in the inner cavity to lift the inner shell and move it to the inside of the outer shell;

[0004] The above-mentioned device points out that when the air source heat pump is in use, hot water can be heated by compressing the air. However, when the air source heat pump is in use, impurities and dust in the air need to be filtered to prevent impurities from flowing into the interior of the air source heat pump, which may cause damage to the air source heat pump when it rotates at high speed. In the above-mentioned device, a cleaning protection net is installed inside the device. The cleaning protection net can filter dust and reduce the problem of dust entering the interior of the air source heat pump. However, negative pressure will be generated when the gas circulates. Negative pressure will cause dust in the air to continue to adhere to the outside of the filter. As time accumulates, the impurity content will increase. When the impurity content increases, it will cause the outside of the filter to be blocked. The blockage of the filter will affect the use efficiency of the air source heat pump. For this reason, we propose an air source heat pump water heater. Utility Model Content

[0005] In view of the shortcomings of existing air source heat pump water heaters, the utility model provides an air source heat pump water heater, which has the advantages of being sleeved on the inside of an air inlet pipe through a rotating filter screen, and filtering the dust passing through. At the same time, when the gas circulates, the rotating filter screen is driven to rotate through the air inlet pipe. At the same time, the rotating filter screen rotates, and impurities adhered to the outside of the rotating filter screen can be scraped off, thereby avoiding the accumulation and clogging of impurities on the outside of the rotating filter screen, thereby solving the problems raised in the above-mentioned background technology.

[0013] Compared with the existing air source heat pump cold and hot water heater, the utility model has the following beneficial effects:

[0014] 1. The air source heat pump water heater is connected to the inside of the air inlet pipe through a rotating filter. At the same time, when the air duct drives the gas to be transported to the inside of the control housing, after the gas passes through the inside of the rotating filter, the gas pushes the spiral blades to rotate, and the spiral blades drive the rotating filter to rotate synchronously. When the rotating filter rotates, the rotating filter rotates inside the air inlet pipe. When impurities adsorbed in the air adhere to the outside of the rotating filter, the rotating filter can drive the impurities to be scraped off when the rotating filter rotates, thereby avoiding the problem of impurities being transported to the inside of the control housing along the air duct, causing damage to electrical components.
