Cleaning type solar water heater with pressurization function

Abstract

The invention relates to a cleaning type solar water heater with a pressurizing function. The cleaning type solar water heater comprises a water tank, a water pipe, at least two heat collecting pipes,a pressurizing mechanism and a cleaning mechanism, wherein the pressurizing mechanism comprises a driving assembly and at least two pressure control assemblies, the pressure control assemblies comprise sliding rods, piston blocks, sealing sleeves, connecting wires and springs, the cleaning mechanism comprises a filter screen, a cleaning assembly, a slag discharge pipe, a cone bucket and a collecting cylinder, and the driving assembly comprises a motor, a first gear, a second gear, a driving shaft and two installation bearings, and the cleaning assembly comprises a supporting rod, a supportingbearing, a paddle blade, a connecting shaft and a cleaning brush. In the cleaning type solar water heater with the pressurizing function, the water pressure of water drained from the solar water heater can be increased through the pressurizing mechanism, the practicability of the solar water heater is improved, scale in the solar water heater can be cleaned through the cleaning mechanism, and thewater quality 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 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. 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 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.
