Problems solved by technology

[0003] The water tank of most solar water heaters is provided with an overflow hole and a vent hole above the tank. When the water tank is full, it will flow out from the overflow hole. When winter comes, due to the influence of temperature, it is easy to cause overflow. The orifice is blocked, which is easy to cause a great impact on the inside of the water tank

Abstract

The invention relates to a solar energy water heater comprising a water tank, the side surface of the water tank is provided with a water inlet and a water outlet, one row of air tubes extend upwards from the bottom of the water tank and extends to the top in the water tank after passing through the bottom of the water tank, and the upper end of an exhaust tube is in a bevel shape. The invention has the benefit that the invention can cause residual water in the water tank to automatically overflow so as to limit water level height and bring excellent venting effect, thus effectively protecting the normal work of the water tank. The tail of the exhaust tube is performed with water seal to effectively prevent external impurities from polluting water in the water tank.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar water heater. Background technique [0002] The many advantages of solar water heaters have been gradually recognized by people. With the improvement of people's quality of life and living conditions, solar water heaters have entered thousands of households, and their demand has also increased significantly. In a populous country like my country, The production of solar water heaters has developed into a huge industry, and the product update speed is also very fast, and the internal quality requirements for solar water heaters are getting higher and higher, such as water tank quality, heat preservation effect, service life, heat collection efficiency of glass heat collection tubes , service life, etc., have become the focus of manufacturers. [0003] The water tank of most solar water heaters is provided with an overflow hole and a vent hole above the tank. When the w...
