Clean solar water heater with pressurization function

Abstract

The invention relates to a clean solar water heater with a pressurization function. The water heater comprises a water tank, a water pipe, two or more heat collection pipes, a pressurization mechanismand a cleaning mechanism. The pressurization mechanism comprises a driving assembly and two or more pressure control assemblies. Each pressure control assembly comprises a slide rod, a piston block,a seal sleeve, a connection line and a spring. The cleaning mechanism comprises a filter screen, a cleaning assembly, a residue discharging pipe, a cone hopper and a collection cylinder. The driving assembly comprises a motor, a first gear, a second gear, a driving shaft and two mounting bearings. The cleaning assembly comprises a supporting rod, a supporting bearing, a paddle, a connection shaftand a cleaning brush. According to the clean solar water heater with the pressurization function, the pressurization mechanism can increase the pressure of discharged water of the solar water heater,the practicability of the solar water heater is improved, the cleaning mechanism can remove limescale in the solar water heater, and the quality of water in the solar water heater is improved.

Description

technical field [0001] The invention relates to the field of solar energy equipment, in particular to a clean solar water heater with pressurization 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, and 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 a...

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 in 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. Not only that, the solar water heater of the prior art is in use At this time, the water flows through gravity, which reduces the outlet water pressure of the solar water heater and reduces the practicability of the solar water heater.
