Solar water heater

Abstract

The invention provides a solar water heater. According to the solar water heater, a heating mode of heat conduction and water circulation is adopted, and high-quality hot water can be quickly obtained through a concave filter and an ozone generator. The solar water heater comprises a water tank, a vacuum heat collection pipe, a circulating pipe, the concave filter and the ozone generator. The backlight position of the vacuum heat collection pipe is provided with a reflector for enhancing solar radiation. One end of the water tank is fixedly connected with the circulating pipe, and the other end of the circulating pipe is connected to the lower end of the vacuum heat collection pipe. The water tank communicates with the circulating pipe. The lower end of the vacuum heat collection pipe communicates with a water outlet of the circulating pipe. The circulating pipe is provided with a water feeding pipe. The water tank is provided with a first drain valve and a hot water supply pipeline and connected with the hot water supply pipeline through the concave filter and the ozone generator in sequence. A second drain valve is arranged between the water tank and the concave filter.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar water heater. Background technique [0002] Solar water heaters are now more commonly used new hot water devices, which convert solar energy into heat energy and then heat water to obtain domestic water at a certain temperature. [0003] Existing solar water heaters are not only complicated in structure and high in production cost, but also have the following disadvantages when in use: [0004] 1. The water in the vacuum heat collecting tube cannot be circulated, resulting in the formation of dirt deposits and adhered to the inner wall of the vacuum heat collecting tube, reducing the efficiency of its heat collection; [0005] 2. The water in the vacuum heat collecting tube cannot be circulated, and the long-term formation of dirt deposits is easy to form harmful substances and germs. After a long time, bacteria are easy to breed inside the water heater, affecting t...

Problems solved by technology

[0003] Existing solar water heaters are not only complicated in structure and high in production cost, but also have the following disadvantages when in use:

[0004] 1. The water in the vacuum heat collection tube cannot be circulated, resulting in the formation of dirt deposits and adhered to the inner wall of the vacuum heat collection tube, reducing its heat collection efficiency;

[0005] 2. The water in the vacuum heat collecting tube cannot be circulated, and the long-term formation of dirt deposits is easy to form harmful substances and germs. After a long time, bacteria are easy to breed inside the water heater, affecting the safety and health of users;

[0006] 3. The lower end of the vacuum heat collecting tube is in a sealed state, and the water circulation cannot be realized, so that the temperature of the water heater tank is increased by a single heat conduction, and the efficiency is low
