Automatic control device and self-adjusting control method for water amount of solar water heater

Abstract

The invention discloses an automatic control device for the water amount of a solar water heater. The automatic control device comprises a water feeding pipe, a water conveying pump, an automatic control driving circuit and a red and green display unit. The automatic control driving circuit comprises a relay K1 and an electromagnetic valve YV. The red and green display unit comprises an alarm redlamp and a display green lamp. A self-adjusting control method for the water amount of the solar water heater includes the following steps that S100, the range section [V1,V2] of the water amount in aself-cleaning water storage tank is set according to the volume V of the self-cleaning water storage tank of the solar water heater, wherein V1 is smaller than V2, and control over automatic water feeding or automatic water cutting of the self-cleaning water storage tank is achieved; S200, the water level in the self-cleaning water storage tank is monitored in real time through a water level sensor, and water level data are transmitted to a main control system in real time; and S300, the main control system receives the water level data transmitted by the water level sensor, and the water level data are compared with the water amount range section preset in S100. The automatic performance is high, operation is easy and convenient, and great convenience is brought to water utilization in daily life of people.

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;
