Abstract

The invention discloses a water-saving control device. When hot water is required to be drained, a switch on a water tap is started and is connected with a control circuit and a temperature control sensor detects a temperature value; when the temperature is lower than a set value, the control circuit outputs a high level, a solenoid valve and a water pump are started and cold water in a third pipeline flows into a water heater through the solenoid valve and a second pipeline; when the temperature is higher than or equal to the set value, the control circuit outputs a lower level, the solenoid valve and the water pump are closed and hot water in the third pipeline flows into the water tap through the solenoid valve and a fourth pipeline and flows out. According to the water-saving control device disclosed by the invention, direct drainage of the cold water when the water tap is just opened is avoided, and thus the waste of fresh water resources is avoided and water resources are saved.

Description

A kind of water-saving control device
Technical field
The present invention relates to a kind of water-saving control device, relate in particular to one and can realize in the time fetching boiling water tap, cold water can not flow out from tap, but flow to water heater, circulate, in the time of hydro-thermal, directly automatically flow out hot water from tap, avoided the water-saving control device of the waste of freshwater resources.
Background technology
Have data to show, China is a country that drought and water shortage is serious, per capita freshwater resources only for world average level 1/4, rank 110 in the world, be one of whole world water resource is the poorest per capita country.Available water resource is only 900 cubic metres per capita, and distributed pole is unbalanced.In 20 end of the centurys, the whole nation has more than 400 city to have insufficient water problem in more than 600 city, and wherein more serious lack of water city reaches 110, and National urban lack of water total amount is 60 billion cubic meters.According to monitoring, most urban groundwaters are polluted to a certain extent, and have the trend increasing the weight of year by year.The water being on the rise pollutes the use function that has not only reduced water body, the contradiction of further having aggravated shortage of water resources, but also serious threat is to city dweller's safe drinking water and health.For alleviating severe water situation, need using water wisely by all kinds of means, create a water-saving society.
At present, there are the electric heater of use or gas heater in the places such as vast family and hotel, school dormitory, in the time that needs use hot water, the tap of fetching boiling water can first be put cold water a little while, then be only out hot water, be finished hot water and turn off tap, the tap of fetching boiling water again a moment later, still first emit cold water, be then only out hot water.Each use is all such circulation, and in most cases, cold water all can directly be emitted, and entire society will waste a large amount of freshwater resources like this.Therefore, also there is high-power Instant heating type tap, but because heater power is larger, and unite two into one with tap, while discharging water after use a period of time, there is the potential safety hazard of electric leakage, to not still being a large-scale application to the greatest extent.
For this reason, we have researched and developed one and can realize in the time fetching boiling water tap, and cold water can not flow out from tap, but flows to water heater, circulate, and in the time of hydro-thermal, directly automatically flow out hot water from tap, have avoided the water-saving control device of the waste of freshwater resources.
