Description

Technical Field

[0001] The utility model relates to the field of air energy water heaters, in particular to an air source heat pump water tank component and an air energy water heater. Background Art

[0002] Air-energy water heater, also known as "air source heat pump water heater", has a working principle very similar to that of an air conditioner. It uses a small amount of electrical energy to drive the compressor. The high-pressure liquid working fluid evaporates into gas in the evaporator after passing through the expansion valve and absorbs a large amount of heat energy from the air; the gaseous working fluid is compressed by the compressor into a high-temperature, high-pressure liquid, and then enters the condenser to release heat and heat the water.

[0003] The existing device drives the magnetic stirring shaft to rotate at the bottom of the inner tank through a magnetic stirrer, thereby stirring the water at the bottom, accelerating the mixing of cold and hot water in the water heater, effectively alleviating the stratification of cold and hot water in the inner tank, making the water temperature in the water heater tank rise more steadily, and increasing the speed of heating the water in the inner tank.

[0004] When the above-mentioned water heater tank and air energy water heater are in use, the scale on the inner wall of the water tank cannot be scraped off, and the scale will accumulate after a long period of use, affecting the water quality. Utility Model Content

The limit rod limits the piston disk and makes the piston disk slide up and down along the direction of the reciprocating screw.
