Solar water heater with auxiliary heater

Abstract

The invention discloses a solar water heater with an auxiliary heater. The solar water heater with the auxiliary heater comprises a water storage tank, the auxiliary heater, an installation frame, a heat collecting tube, a sealed connection piece, a water inlet pipe, a water outlet pipe, a rainwater collecting tank, a water collecting groove, a water return pipe, a filter screen, a heat collectingtube cleaning assembly and a reflector plate angle adjusting assembly, wherein the auxiliary heater is arranged in the water storage tank; the water storage tank is connected with the installation frame; the installation frame is provided with a front support frame and a back support frame; the front support frame is connected under the heat collecting tube; the upper end of the heat collecting tube communicates with the water storage tank through the sealed connection piece; the heat collecting tube is connected with the heat collecting tube cleaning assembly; and the back support frame is connected with the reflector plate angle adjusting assembly. According to the solar water heater with the auxiliary heater provided by the invention, the double-layer heat collecting tube is arranged,and a heat conducting fin is matched for transferring heat, so that cold water in the heat collecting tube is heated uniformly; by utilizing the belt drive and the pulling of a pulling rope I, the surface of the heat collecting tube is cleaned, so that a heat collecting performance is ensured; and a bevel gear I meshes with a bevel gear II so as to wind and unwind a pulling rope II, and the angleof a reflector plate is adjusted, so that sunshine is reflected to the back surface of the heat collecting tube, and a heat collecting performance of the heat collecting tube is improved.

Description

technical field [0001] The invention relates to the technical field of energy utilization equipment, in particular to a solar water heater with an auxiliary heater. Background technique [0002] Solar water heater is a heating device that converts solar energy into heat energy. It uses solar energy to heat cold water to meet the needs of people's daily life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. Among them, vacuum tube solar water heaters are more common, accounting for 95% of the domestic market share. Vacuum tube solar water heaters use heat collecting tubes to collect solar energy and convert it into heat energy. The cold water in the heat collecting tubes floats after being heated by heat energy. sinking, thereby circulating heating, which is convenient for people's daily life.
