Water-saving device capable of being simply and conveniently installed on hot water faucet based on existing family arrangement

Abstract

The invention provides a water-saving device capable of being simply and conveniently installed on a hot water faucet based on existing family arrangement. The water-saving device comprises a water inlet pipeline (2), a water outlet pipeline (9), a recycled water outlet (7), a recycled water storage tank (8) and an electromagnetic valve (6). After the hot water faucet is opened, residual cold water in a hot water supply pipeline is firstly recycled in the water storage tank (8) through the electromagnetic valve (6) according to a water-saving strategy, and after the hot water arrives, the electromagnetic valve (6) guides the hot water to the hot water faucet to flow out for use. The water-saving device is simply connected in series between the hot water supply pipeline and the hot water faucet, so that the original water supply pipeline does not need to be modified, and the installation is simple and convenient. It is guaranteed that a user does not need other preparatory work before using hot water, the hot water faucet is directly opened, residual cold water in the water supply pipeline is recycled and stored firstly, then the user waits for the hot water, the learning cost of the user is eliminated, and waste of water resources is avoided.

Description

technical field [0001] The present invention relates to a water-saving device, in particular to a water-saving device based on the arrangement of existing domestic water pipelines, which can be easily installed at the end of hot water supply such as a hot water faucet. Background technique [0002] In daily life, the water heater is often a certain distance away from hot water faucets such as showers and kitchens. When you turn on the hot water faucet, you can only drain the residual cold water in the channel first. With a distance of 10 meters, the commonly used household water heater with a diameter of 25 mm and a wall thickness of 3 mm Taking the water pipe as an example, the amount of water that needs to be drained each time is 2.8 liters. This results in a greater waste of water resources. [0003] There are mainly three types of solutions currently searched: Type 1 is to lay a return water circuit and a water return device, and to keep the water in the pipeline heated...

AI Technical Summary

Problems solved by technology

[0005] The existing technology cannot achieve a balance in terms of economy and energy saving, and all of them need to go through complicated line transformation and construction

It causes water saving in real life but costs electricity and gas, technical implementation, installation and construction are complicated and difficult to promote, this kind of water waste problem exists objectively but it is difficult to solve it for a long time, etc.
