Hand touch type switch device of solar water heater

Abstract

The invention discloses a hand touch type switch device of a solar water heater, and relates to the technical field of solar water heater accessories. The hand touch type switch device comprises a heat exchange base, an adjusting ring, a heat conduction touch cover, a hot water pipe, a cold water pipe and a water outlet pipe. The hot water pipe and the cold water pipe are symmetric and are communicated with an inner cavity of the heat exchange base. The water outlet pipe is communicated with the inner cavity of the heat exchange base in the direction perpendicular to the hot water pipe. The water outlet pipe is communicated with a water guiding pipe in the vertical direction in the heat exchange base. The horizontal position of the water guiding pipe is located in the center of the heat exchange base. Two triangular holes are symmetrically formed in the side wall of the adjusting ring and are matched with the hot water pipe and the cold water pipe in position respectively. Between the two triangular holes, a transmission plate penetrating the axis of the adjusting ring is arranged on the adjusting ring. A pipe cavity of a tubular supporting shaft and the inner cavity of the heat exchange base are communicated through a water inlet hole. The hand touch type switch device has the beneficial effects that a human body directly touches and inducts the temperature of mixed water, the mixing proportion of cold water and hot water is adjusted, and the problem of delayed temperature induction is solved.

Description

technical field [0001] The invention relates to the technical field of solar water heater accessories. Background technique [0002] Solar water heaters have gone through more than 20 years of development in China, and the main technology has matured. At present, solar water heaters have been widely used. Although the mixing valve is one of the many parts of the solar water heater, it is very important. It is directly related to the comfort of people's bathing. At present, most of the mixing valves on the market are manually controlled, and their structures are mostly composed of valve core, valve body, sealing ring, handle, etc. The temperature of the water outlet is adjusted by the rotation of the handle. Hot and cold conditions, and the adjustment process is troublesome. [0003] For the situation of hot and cold during temperature adjustment, it can be seen from the structure of the traditional mixing valve that the main problem is that it takes a certain time for the ...

AI Technical Summary

Problems solved by technology

[0003] For the situation of hot and cold during temperature adjustment, it can be seen from the structure of the traditional mixing valve that the main problem is that it takes a certain time for the mixed water to reach the nozzle after passing through the outlet pipe and valve. The temperature of the nozzle is different, so there is a phenomenon of temperature perception delay. Because of the delay of temperature perception, it cannot be fed back to the mixing valve for regulation in time.
