Solar water heater with self-cleaning function

Abstract

The invention relates to a solar water heater with a self-cleaning function. The solar water heater comprises a water tank, a mounting plate, at least two sealing sleeves, at least two heat collectiontubes, a first cleaning mechanism and at least two second cleaning mechanisms, wherein the first cleaning mechanism comprises a power assembly, a driving shaft, two first bearings and two cleaning assemblies, the cleaning assemblies comprise cleaning strips, two support sleeves, two springs and two support rods, the two second cleaning mechanisms comprise connecting lines, cleaning blocks, elastic ropes, collecting drums, buckles and at least two through holes, and the power assembly comprises a second bearing, a rotating shaft, a half gear, a first gear and a wind cup. According to the solarwater heater with the self-cleaning function, the water tank can be cleaned by the first cleaning mechanism, so that the water quality in the water tank is increased; the heat collection tubes can becleaned by the second cleaning mechanisms, so that the heat conduction efficiency of the heat collection tubes is improved, and the heating efficiency of the solar water heater is improved.

Description

technical field [0001] The invention relates to the field of solar energy equipment, in particular to a solar water heater with self-cleaning function. Background technique [0002] A solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet the hot water use in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. The vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. Get the hot water you need. [0003] After the solar water heater of the prior art has been used for a long time, a large amount o...

AI Technical Summary

Problems solved by technology

[0003] After the solar water heater of the prior art has been used for a long time, a large amount of scale will accumulate inside the water tank of the solar water heater, which not only affects the water quality, but also reduces the heating efficiency of the solar water heater. One end of the heat pipe is in a sealed state, making it difficult to clean the scale inside the heat collecting pipe, which reduces the convenience of cleaning the solar water heater
