An air source heat pump water heater with air replacement function

Abstract

The invention discloses an air source heat pump water heater with an air replacement function, which comprises a hot water tank. The inside of the hot water tank is provided with a first cavity and a second cavity. The top end of the inner wall of the first cavity is fixed A water inlet tank is connected, and the bottom end of the inner wall of the water inlet tank is rotatably connected with a rotating rod penetrating to the bottom of the water inlet tank, and the outer wall of the rotating rod is located inside the water inlet tank and is fixedly connected with fan blades. The present invention can drive the fan blades to rotate through the set water flow, and the rotation of the fan blades can drive the rotating rod to rotate, and the rotating rod can drive the rotating shaft to rotate, so that the slider can slide inside the chute, and then the collecting funnel can be rotated in the spiral air. The external spiral sliding of the cold pipe can then scrape the scale on the outer wall of the air-cooled pipe, so that the heat of the high-temperature refrigerant gas inside the air-cooled pipe can directly contact the cold water through the pipe wall of the air-cooled pipe, avoiding the scale on the outer wall of the air-cooled pipe more and affect the heating rate.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an air source heat pump water heater with an air replacement function. Background technique [0002] With the development of society and economy, people's requirements for the quality of life are getting higher and higher. Taking showers as an example, gas water heaters, electric water heaters, solar water heaters, etc. are far from meeting people's needs for comfort, energy saving and safety. Therefore, an air source heat pump water heater based on the principle of heat pump cycle has been widely used. The air source heat pump water heater is mainly composed of an evaporator, a compressor, an air cooler and an expansion valve. Evaporation, refrigerant vapor constant entropy compression, refrigerant isobaric cooling, and refrigerant liquid constant entropy expansion are composed of four cycle processes. When working, it uses the evaporator and the fan to absorb the low-temp...

Problems solved by technology

[0003] However, the air-cooled tube inside the existing air-source heat pump water heater with air replacement function is soaked in water for a long time, and the water in the water heater is only commonly used tap water. A lot of scale prevents the outer wall of the air-cooled tube from directly contacting the tap water, which affects the heating speed of the tap water, and the long-term existence of scale will also reduce the service life of the air-cooled tube
