A solar water heater water volume automatic control device and self-regulating control method

Abstract

The invention discloses a water quantity automatic control device for a solar water heater, which comprises a water supply pipe, a water delivery pump, a self-control drive circuit and a red-green display unit; the self-control drive circuit includes a control relay K1 and a solenoid valve YV, and the red-green display unit includes an alarm red light and a display Green light; the water volume self-regulation control method includes the following steps: S100, according to the volume V of the self-cleaning water storage tank of the solar water heater, set the range interval [V1, V2] of the water volume in the self-cleaning water storage tank, wherein V1 is less than V2, to realize the self-cleaning water storage tank. Control of automatic water filling or automatic water cut-off of self-cleaning water storage tank; S200, real-time monitoring of the water level in the self-cleaning water storage tank through the water level sensor, and real-time transmission of water level data to the main control system; S300, main control system receives the water level data transmitted by the water level sensor , and compared with the preset water volume range in step S100, the automation performance is high, the operation is simple, and it brings great convenience to people's daily use of water.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a water volume automatic control device and a self-regulating control 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 exchang...

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;
