Solar water heater

Abstract

The invention discloses a solar water heater which comprises a protecting plate, a base, a protecting frame, heat collecting pies, a supporting plate, a control panel, a heat preservation layer and ultraviolet sterilizing lamps. The supporting plate is arranged at the upper ends of supporting rods, the heat collecting pipes are embedded into one end of a water tank, the heat preservation layer isarranged on the inner wall of the water tank, and the ultraviolet sterilizing lamps are arranged in a protecting hood; and the protecting frame is arranged on one side of the heat collecting pipes, the protecting plate is arranged on the other side of the heat collecting pipes, and the control panel is arranged on the front surface of an outer end cover. The solar water heater is scientific and reasonable in structure and safe and convenient to use, the ultraviolet sterilizing lamps can be conveniently used by a user for killing harmful microorganisms in the water tank, the protecting plate can be conveniently used by the user to protect the heat collecting pipes, the supporting plate can be conveniently used by the user to protect and disassemble the bottom of the water tank, and convenience is brought to normal using for the user.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a solar water heater. Background technique [0002] Solar water heaters are devices that use sunlight to heat water. Solar water heaters are divided into collector tube solar water heaters and flat plate solar water heaters. The heat energy mainly depends on the vacuum heat collecting tube, and utilizes the principle that hot water floats up and cold water sinks to make the water produce microcirculation to achieve the required hot water. [0003] Solar water heaters currently on the market have single functions and poor safety protection measures, which are not conducive to prolonging the service life of solar water heaters. Existing solar water heaters are all installed outside, exposed to the wind and sun all the year round, the heat collecting tubes tend to accumulate more dust, which greatly reduces the heating efficiency of solar water heaters, and the stubborn...

Problems solved by technology

[0003] At present, the functions of solar water heaters on the market are relatively single, and the safety protection measures are poor, which is not conducive to prolonging the service life of solar water heaters.

Existing solar water heaters are all installed outside, exposed to the wind and sun all the year round, the heat collecting tubes tend to accumulate more dust, which greatly reduces the heating efficiency of solar water heaters, and the stubborn stains on the heat collecting tubes that are difficult to be washed away by rainwater will Staying on the outer wall of the heat collecting tube for a long time greatly affects the aesthetics of the solar water heater. At the same time, because the solar energy is mostly located at a higher position, it is more troublesome for people to clean
