Description

Technical Field

[0001] The present application relates to the field of air-energy water heaters, and in particular to a defrosting device for air-energy water heaters. Background Art

[0002] Air-energy water heaters are also called "air source heat pump water heaters". Their working principle is very similar to that of air conditioners. Air-energy water heaters use a small amount of electricity 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. This continuous cycle of heating can heat the water to 50°C-65°C. When using a conventional air-energy water heater, after the water heater body is stabilized with the help of the base frame, the water is heated with the help of the water heater, and a shielding net is installed on the surface of the water heater. The shielding net is used to shield the surface of the water heater to prevent external impurities from entering the inner wall of the body.

[0003] With respect to the above-mentioned related technologies, the inventors believe that when the external ambient temperature is low, frost is likely to form at the exhaust port of the water heater, causing the water heater to consume more energy when in use, and the water heater is likely to be damaged if used in a frosted state for a long time.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
