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, a

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0019] Such as figure 1 As shown, the shell 1 is a spherical hollow structure, which can be formed by buckling the upper and lower halves. The shell 1 is a three-layer composite structure, from the inside to the outside are the inner metal layer 1a, the polyurethane layer 1b and the outer metal layer 1c, the inner and outer metal layers 1a, 1b can be made of stainless steel or other equivalent materials, and the polyurethane layer 1b starts The role of heat preservation. A sewage discharge pipe 28 is vertically installed at the bottom of the housing 1 , and the sewage discharge pipe 28 communicates with the inner cavity of the housing 1 , and a sewage discharge valve 29 is installed on the sewage discharge pipe 28 . Open the drain valve 29, and the scale and impurities in the spherical housing 1 can be completely discharged through the drain pipe 28.

Abstract

The invention discloses a solar water heater automatic regulating device. A hot water pipe is connected with the lower part of a casing, a temperature sensor and an infrared heating rod pass through the wall of the casing and extend into an inner cavity of the casing, a thermostat is arranged on the upper part of the inner cavity of the casing, an inner cavity of the thermostat is communicated with the inner cavity of the casing through a hot water inlet, a cold water inlet of the thermostat is connected with a cold water pipe which is extended out of the casing, and a second one-way valve is arranged in the cold water pipe. A water outlet pipe which is connected with the top of the thermostat is communicated with the inner cavity of the thermostat and is extended out of the casing. The solar water heater automatic regulating device can automatically regulate the water temperature and keep the temperature of the outputted water constant. In addition, the fluctuation of the temperature of the outputted water is as low as between 2 DEG C below and 2 DEG C, thereby avoiding scalding or cold catching caused by extremely-high water temperature or extremely-low water temperature. When a solar water heater is used in winter, the solar water heater automatic regulating device can output hot water in less than two seconds. The device not only has convenient use and improved bath comfort, but also avoids water resource waste. 3 to 6 liters of water can be saved for 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...
