Water-heater water saving system

Abstract

The invention relates to a water-heater water saving system which comprises a water heater (1), a water outgoing pipe (2), a water faucet (3), a diversion pipe (7), a water collector (8), a control module (4), a water temperature measuring sensor (5), an electric control valve (6) and a power source. The water temperature measuring sensor (5), the electric control valve (6) and the power source (9) are connected with the control module (4) respectively, the water temperature measuring sensor (5) is arranged in the water outgoing pipe (2), the electric control valve (6) is arranged on the water outgoing pipe (2) and positioned in rear of the water temperature measuring sensor (5) along the water flow direction, the electric control valve (6) is connected with one end of the diversion pipe (7), and the other end of the diversion pipe (7) points at the water collector (8). Aiming at the defects of an existing water heater, an electric control structure is designed, water discharging temperature is monitored in real time, and cold water at the early stage of water discharging is automatically collected according to realtime monitoring results, so that waste of water resources is avoided effectively.

Description

technical field [0001] The invention relates to a water-saving system for a water heater. Background technique [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles; it can be divided into electric water heaters, gas water heaters, solar water heaters, and air energy water heaters according to different principles; But there is a common problem, that is, the hot water cannot be produced in time for a few seconds or even longer when the water is turned on. In this way, the cold water cannot be used, which will cause waste of cold water. Although the cold water in this short period of time is not used How much, but in the long run, it will also cause waste of water resources. Contents of the invention [0003] In view of the above-mentioned technical problems, the technical problem to be solved by the present invention is to provide a water-saving system for wat...
