Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to an automatic cleaning device for a solar water heater. Background Art

[0002] Solar water heaters are devices that use sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters occupy 95% of the domestic market share. Vacuum tube household solar water heaters are composed of related parts such as collector tubes, water storage tanks and brackets. The conversion of solar energy into thermal energy mainly relies on vacuum collector tubes. The principle of hot water floating and cold water sinking is used to make water microcirculate to achieve the required hot water. Since solar water heaters need to be placed in an open and unobstructed place, a lot of dust and dirt will accumulate on the surface of the collector tubes after long-term use, especially on the upper surface. At the same time, the water used in solar water heaters is mostly untreated water such as tap water. The change of temperature will form a lot of scale, which further affects the thermal efficiency of the collector tube and the use effect of the solar water heater.

[0003] After searching, the existing patent (publication number: CN107461947A) discloses an automatic cleaning device for solar water heaters, including a trolley, a distribution box, a circulating water tank, a steam water tank, a circulating water pump, a steam water pump, an electric heating evaporator, an electromagnetic descaling device, a trailer, a drying gas pipeline, a steam pipeline, a constant pressure exhaust valve, a filter, a sobbing pump, an electric heater and a connecting pipe. The present invention adopts electromagnetic descaling technology, which is safe and efficient, and avoids the corrosion of the water heater and the harm to the human body caused by the residual reagents after the traditional chemical reagent descaling. At the same time, high-pressure steam is used to clean the surface of the heat collecting tube and dried with hot air. The thermal decomposition function of steam is used to quickly dissolve the sticky nature of mud and stains, allowing them to detach from the heat collecting tube, saving water and not causing damage to the surface of the heat collecting tube.

[0004] It uses dry hot air to dry the surface of the cleaned collector tube. When the solar water heater is cleaned in winter, the collector surface will not freeze. However, it has a disadvantage that it has no waste water recovery mechanism, which will cause a waste of water resources. Utility Model Content
