Intelligent water-saving device for domestic water heater

Abstract

The invention relates to an intelligent water-saving device for a domestic water heater, and belongs to water-saving devices for detecting temperature changes to achieve the water-saving function. A core module capable of controlling motion of a stepping motor by detecting water temperature changes and a water outlet pipe are arranged in the water-saving device, and the water outlet pipe can detect water temperature and is provided with a temperature sensor. The lower portion of the water outlet pipe is connected with a water pipe so that hot water and cold water can be separated, wherein a rotatable cold and hot water semicircular water stop sheet controlled by the stepping motor is mounted on the water pipe. The separated cold water is directly connected with a cold water inlet of the domestic water heater. According to the technical scheme, when a general domestic water heater just works, cold water which does not reach the temperature at a hot water outlet is separated out to continue to be used, waste of water resources is avoided, and the hot water mode can be switched back in time. According to the scheme, the good water-saving function is achieved.

Description

technical field [0001] The invention relates to the field of energy saving of water heaters, in particular to an intelligent water saving device for household water heaters. Background technique [0002] With the development of social industry, various high-efficiency water heaters emerge in endlessly in terms of household water heaters, and the efficiency of water heaters is also getting higher and higher. Today's electric water heaters, solar water heaters, and air energy water heaters are becoming more and more common, but they are still There are certain problems, that is, when the water heater just started working, the outlet water temperature of the water outlet was not high, causing the cold water with insufficient temperature to be directly let off and causing a waste of water resources. The method can divert the cold water and return it to the cold water inlet for reuse, thereby avoiding the waste of water resources to a certain extent. Contents of the invention ...
