Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to a self-cleaning air source heat pump water heater. Background Art

[0002] Air source heat pump water heater, also known as air energy water heater, is composed of an insulated water tank and an outdoor unit. The outdoor unit is called an air energy heat pump unit. The working principle of the air energy water heater is to absorb the low-temperature heat in the air, gasify it through the fluorine medium, and then compress it through the compressor to increase the pressure and temperature, and then convert it into water heating through the heat exchanger. The compressed high-temperature heat energy is used to heat the water temperature. When the air energy heat pump unit is working, under the suction of the fan, ordinary outdoor air enters the inner cavity of the unit from the air inlet and flows through the heat exchanger. At this time, the energy in the air is transferred to the heat exchanger. Absorbed and transferred to the insulated water tank, the temperature of the air that loses energy for water heating is lowered, and it becomes cold air blown out from the fan. The air-energy water heater is highly efficient and energy-saving. It produces 4-6 times the amount of hot water as ordinary electric water heaters, avoiding the risk of electric leakage of electric water heaters. The outlet water temperature of existing air-energy water heaters can usually reach 50 to 60 degrees Celsius. Not only will scale form on the outer wall of the heat exchange tube, but a lot of dirt will also accumulate on the inner wall of the water tank. If the water tank is not cleaned regularly, a lot of residual dirt will accumulate in the water tank, affecting the safety and sanitation of the water quality.

[0003] In the prior art, a Chinese patent with the announcement number CN210399505U discloses an air-energy water heater that is convenient for self-cleaning, including a water tank and a heat exchange tube, wherein the bottom of the water tank is rotatably connected with a shaft, and a first ring is slidably connected to the side surface of the shaft, and the first ring is fixedly connected to the same side surface with a second ring through a connecting rod, and the inner wall of the second ring is slidably connected to the outer wall of the heat exchange tube, and a brush is fixedly connected to the side surface of the second ring through a connecting rod, and a surface of the brush is slidably connected to the inner wall of the water tank. Although the dirt on the outer wall of the heat exchange tube and the inner wall of the water tank is cleaned and brushed off, when filtering the dirt mixed with the water source, the dirt is intercepted and then squeezed and scraped on the filter plate by the first brush plate and the second brush plate to scrape the dirt off, but in this way, part of the dirt will be squeezed into the filter hole of the filter plate and stuck, and the dirt will also be flushed into the inner side of the filter hole on the filter plate when the water flow impacts, and after a period of use, it will be blocked, which will affect the subsequent filtering effect.
