Solar water heater automatic adjustment device

Abstract

The invention relates to a solar water heater automatic adjustment device. A hot water pipe is connected to the lower portion of a shell. A temperature sensor and an infrared ray heating rod penetratethe wall of the shell and extend into an inner chamber of the shell. The upper portion of the inner chamber of the shell is provided with a temperature controller. An inner chamber of the temperaturecontroller communicates with the inner chamber of the shell through a hot water inlet. A cold water pipe is connected to a cold water inlet of the temperature controller, extends out of the shell andis provided with a second one-way valve. A water outlet pipe is connected to the top of the temperature controller, communicates with the inner chamber of the temperature controller and extends out of the shell. By means of the solar water heater automatic adjustment device, the water temperature can be adjusted automatically, and the temperature of output water is maintained to be constant; in addition, the temperature fluctuation of the output water is small and only + / -2 DEG C, and thus, the problem that a user is scalded or gets a cold due to the fact that the water temperature is excessively high or low is avoided; when a solar water heater is used in winter, the solar water heater automatic adjustment device can output the hot water within two seconds, and the solar water heater automatic adjustment device is convenient to use, and the shower comfort level is effectively raised; and in addition, waste of water resources is avoided, and 3-6 L of water can be saved each time.

Description

technical field [0001] The invention relates to a solar water heater, in particular to an automatic adjustment device for the solar water heater. 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 is nece...

Problems solved by technology

Because the outdoor hot water pipe is long and the outdoor temperature is low, a lot of heat will be lost due to heat radiation when transferring hot water, so that when the water is discharged, the cold water will be released first, and the hot water will be released after 1 minute, so people use it in winter. It is very inconvenient when bathing, and it is easy to catch a cold. Not only is the comfort of bathing poor, but it also causes a waste of water resources.
