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

technical field [0001] The invention relates to a water-saving control device, in particular to a device capable of realizing that when the water tap is turned on, cold water does not flow out from the water tap, but flows into the water heater for circulation, and when the water is hot, hot water flows out directly and automatically from the water tap , A water-saving control device that avoids the waste of fresh water resources. Background technique [0002] Statistics show that my country is a country with severe drought and water shortage. The per capita fresh water resources are only 1 / 4 of the world's average level, ranking 110th in the world, and it is one of the countries with the poorest per capita water resources in the world. The per capita available water resources are only 900 cubic meters, and the distribution is extremely uneven. At the end of the 20th century, more than 400 of the more than 600 cities across the country suffered from insufficient water suppl...
