A solar water heater water pretreatment device and method

Abstract

The invention discloses a solar water heater water pretreatment device. A pretreatment box is included. One end of the pretreatment box is connected with a faucet through a water feed pipe A, and theother end of the pretreatment box is connected with a self-cleaning water storage tank through a water feed pipe B. An impurity removal composite net and an automatic incrustation removal assembly forremoving incrustations accumulated on the impurity removal composite net are arranged in the pretreatment box. The automatic incrustation removal assembly comprises a circular-platform-shaped connecting water pipe, one end of the connecting water pipe is connected with the water feed pipe A, the other end of the connecting water pipe is connected with the water feed pipe B, the water feed pipe Bis provided with an incrustation removal control valve, the incrustation removal control valve is connected with a master control system, the impurity removal composite net is arranged in the connecting water pipe, and an incrustation removal liquid inlet pipe and a waste liquid outlet pipe with a valve are arranged at the upper end and the lower end of the connecting water pipe correspondingly. Asolar water heater water pretreatment method comprises the following steps that S100, the impurity removal composite net conducts purification and impurity removal on water entering the self-cleaningwater storage tank; and S200, incrustation removal treatment is conducted on the impurity removal composite net, the automation performance is high, operation is simple and convenient, and great convenience is brought to daily life water utilization for people.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a water pretreatment device and method for solar water heaters. Background technique [0002] Solar water heater is a major industry in the application of solar energy achievements. It has quickly won the favor of consumers for its advantages of environmental protection, safety, energy saving, and sanitation. With the continuous improvement of people's living standards, solar water heaters have entered thousands of households. , solar water heaters absorb the sun's radiant heat, heat cold water, and heat water from low temperature to high temperature to meet people's hot water use in life and production. The use of solar water heaters saves energy while protecting the environment , reducing the cost of home life. [0003] Just as the application number is 201210501126.8 named as an invention of a solar water heater with heat energy exchange, the invention winds a coil in the s...

Problems solved by technology

[0005] (1) The water supply and water cut-off operations of solar water heaters need to be manually controlled by the user. The water supply starts when the tap is turned on, and the water supply stops when the tap is turned off. The operation is relatively simple, but it often occurs due to the negligence of the user that the water supply is excessive. , the water in the solar water heater returns to the bathroom through the overflow pipe, which will cause water to accumulate in the bathroom while causing water waste; in addition, the user cannot obtain the water level information in the solar water heater, and can only judge how much water is used based on life experience. Then decide whether it needs to be filled with water, so that the water in the solar water heater may run out, and the solar water heater may dry out, which may easily cause damage to the solar water heater;

[0006] (2) The water tank of the solar water heater is installed on the roof. If the water tank is used for a long time, scale is easy to accumulate on the inner wall of the water tank. The cleaning operation of the water tank is complicated and needs to be cleaned by a special person. If the solar water heater is not cleaned frequently, it will not only reduce its use value, It will also cause problems such as bursting and water leakage;
