Water-saving temperature control device for water heater

technical field

The utility model discloses a water-saving temperature control device for a water heater, which belongs to the technical field of water heater control.

Background technique

my country is a country seriously short of water, and the per capita water consumption is 27% of the world's (if water is not saved, it will become 0.3% in 27 years). Many places in Guyuan City in the southern mountainous area of Ningxia Hui Autonomous Region are seriously short of water. Villagers spend 3 to 4 hours a day queuing up to get water from the water cellars; 500,000 people in Baiyu Mountains have difficulty getting water; including Shanghai, 33 cities around the world Twenty-one of the largest cities with a population of more than 8 million will eventually face a water supply crisis. In recent years, with the increase of population and the continuous development of social economy, water consumption will continue to increase, which shows that the situation of water resources is very severe. The phenomenon of wasting water is ubiquitous, and the status of saving water is becoming more and more important.

Now water heaters have been widely popularized, and the frequency of use is quite high, but for a long time, there are many problems in the use of water heaters, especially solar water heaters:

(1) Cold water is stored in the pipeline connected between the water heater and the faucet, which is called "ineffective hot water before use", and is often wasted before taking a bath;

(2) It is difficult to adjust the water temperature of the water heater. Sometimes, people take a long time to adjust the water temperature before taking a bath. Not only trouble but also cause waste. Insufficient water supply pressure. In many cases, when the water pressure in the water pipe is insufficient, it will cause the water heater to be difficult to use, which will bring great inconvenience to people's lives.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model provides a water-saving temperature control device for water heaters with automatic temperature control, water saving and energy saving, which is green and environment-friendly.

The utility model is achieved through the following technical solutions:

The utility model comprises a water heater water tank, wherein a water level detector and a water temperature detector are arranged in the water tank, a water pump is arranged on the water supply pipeline connected with the water tank, and a smart water pump is arranged at the connection of the water supply pipeline, the water discharge pipeline and the water outlet pipeline. A controller, and a temperature sensor is installed between the intelligent controller and the water outlet.

Described intelligent controller comprises single-chip controller and flow control valve, and wherein water level detector and water temperature detector and temperature sensor are respectively connected in the control port of single-chip controller, the output port of single-chip is connected with the switch of flow control valve, flow The control valves are respectively installed on the upper water pipeline and the lower water pipeline.

The utility model first borrows the upper water pump before bathing, and returns the cold water in the pipeline to the water heater for mixing. At this time, the cold water in the water pipe of the water heater is naturally replaced with hot water, and the original cold water is saved; Set the water temperature, after receiving the set temperature, the intelligent controller will automatically control the flow controller to adjust the mixing ratio of hot water and cold water according to the cold water temperature and the hot water temperature of the sewage, so that the outlet water temperature meets the user's requirements; at the same time, the system automatically calculates It can output constant temperature water; if the water pressure is insufficient at this time, the water pump will automatically work to increase the water pressure to draw water into the water heater; during use, the system will continuously collect the temperature of the hot water in the water heater and the temperature of the water outlet, and control it in real time through a closed loop , Adjust the ratio of hot and cold water to keep the outlet water temperature constant.

The utility model is a novel energy-saving article suitable for cities, especially rural areas. It can fundamentally solve the problem of "ineffective hot water before use", and the water saving effect is obvious; it realizes automatic and intelligent control of the outlet water temperature, avoiding fluctuations in bath water temperature; it effectively solves the problem that the water heater cannot be used when the water pressure is insufficient. According to preliminary statistics, there are about 150 million water heaters in China. According to the actual water heaters used in households, 12~16L of water will be released every time you take a bath. Based on the average use of each water heater 1.5 times a day, each water heater will save 6570~8760L of water a year, and the country can save 990~1.3 billion a year Cubic meters of fresh water is equivalent to 1.5 times the annual water demand (870 million cubic meters) of the entire city of Beijing in 2000, or about 4 billion yuan.

The utility model is green and environment-friendly, can greatly improve the utilization rate of fresh water resources, and has important social effects and good market development prospects.
