Description

Technical Field

[0002] An air source heat pump water heater is a heat pump water heater that uses air as a low-temperature heat source to produce hot water. The air source heat pump water heater mainly consists of two major parts: an air source heat pump water heater circulation system and a water storage tank. This device transfers the heat in the air to the water by consuming a part of electrical energy.

[0003] The existing patent (Publication No.: CN217929234U) discloses a heat exchange component of an air source heat pump water heater. A partition is arranged in the condenser tank body to divide the tank body cavity into a cold water cavity and a hot water cavity. Through holes communicating the cold water cavity and the hot water cavity are opened on the partition; a turning plate that can be rotated to open or close the through hole is arranged in the through hole; when adding cold water, the through hole is closed so that the cold water cannot enter the hot water cavity. After the cold water cavity is heated for a period of time and the water temperature rises to be not much different from the water temperature in the hot water cavity, the turning plate is opened so that the hot water in the cold water cavity enters the hot water cavity; then the through hole is closed again to add cold water; in this way, the hot water cavity can keep the output water temperature within a certain range. In the process of implementing this solution, it is found that the following problems exist in the prior art and have not been well solved:

[0004] During the use of this heat exchange component, the cold water is simply heated through the heat exchange tube, and the heating efficiency is limited. Moreover, when tap water is directly heated inside the cold water tank during use, scale is easily generated, and it is relatively difficult to clean the scale, which affects the use of the heat exchange component. Summary of the Utility Model

[0013] Through the above technical solution, it is convenient to discharge the water flow inside the cold water tank into the hot water tank through the flip plate, which is convenient for the use of the hot water tank.

[0014] Optionally, in the above-mentioned high-efficiency and environmentally friendly air source heat pump water heater heat exchange component, the water inlet pipe and the threaded block are installed in an integrated manner, the threaded block and the water inlet are connected by a threaded connection, and a corresponding thread is provided on the outside of the water inlet.

[0017] Through the above technical solution, it is convenient to filter tap water through the cooperation between the filter net and the insertion rod to reduce scale generation, and at the same time, the filter net is fixed by the insertion rod.

On the other hand, the inverted buckle protects the water inlet pipe, avoiding the direct impact of water flow on the threaded block and preventing the threaded block from falling off during use. Secondly, by setting an insertion rod to fix the filter screen, the stability of the filter screen is ensured. BRIEF DESCRIPTION OF THE DRAWINGS
