Problems solved by technology

In summer, due to the long time and high intensity of sunlight, the water temperature in the water tank is too high, and the hot water cannot be used directly. It is necessary to rely on the hot water pipe to connect with the tap water pipe, and the water temperature is adjusted by the mixing valve, so that the temperature of the outlet water fluctuates greatly. It often needs to be adjusted repeatedly during use, which is not only troublesome, but also greatly reduces the c

Abstract

The invention provides a solar water heater with a temperature control function. The solar water heater comprises a central controller, a heat collector and a water tank connected with the heat collector, the water inlet of the heat collector is communicated with an external water source through a pipe, the water tank is connected with the heat collector, the water tank and the heat collector are provided with electric heating devices and temperature control devices, and therefore temperature control of the solar water heater can be achieved. According to the solar water heater, heating power can be controlled according to the water temperature, so that an inner container is prevented from being heated rapidly to expand. Meanwhile, the water temperature can be controlled according to the flow rate of water, and uniformity of heating temperature is guaranteed.

Description

technical field [0001] The invention belongs to the field of computer control, in particular to a solar water heater with temperature control function. Background technique [0002] As a clean and renewable energy, solar energy has the advantages of no environmental pollution and no safety hazards, which are unparalleled by other energy sources. With the increasing tension of electricity and gas consumption across the country, solar water heaters are becoming more and more popular. Traditional solar water heaters install heat collecting tubes and water tanks on the roof of the building. The heat collecting tubes absorb the heat of the sun to increase the temperature of the water. Hot water is stored in the water tanks. When needed, hot water is introduced from outdoor hot water pipes. Indoor, for people to use. In summer, due to the long time and high intensity of sunlight, the water temperature in the water tank is too high, and the hot water cannot be used directly. It i...
