Water saver with waste-water backflow reutilizing function for water heater

Abstract

The invention is a water-saving device, it is mainly used to pave with longer water pipe of hot water. Using the device, the water not used in the water pipe will refluence into water tank and can be recycled next time when the user's terminal close the equipment, and when the users start the equipment, cold water will not flow, reversely, the hot water will flow after excluding the air in the water pipe. Water pump and water tank connecting with three terminal adjustable electric control hydrovalve, two shelves electric control selector valve and one-way automatic pressure valve are set up between fill hose and let-off pipe of user terminals. When it works, water tank, two shelves electric control selector valve, water pump, one-way automatic pressure valve and connecting end of water heater's fill hose link together to form a water access, water in the water tank is pressed into connecting end of water heater's fill hose by water pump with a proper pressure; When it is closed, let-off pipe of user terminals, three terminal adjustable electric control hydrovalve, two shelves electric control selector valve, water pump and water tank link together to form a water access, the water of the whole user terminal not used is drew into the water tank by water pump to be recycled.

Description

Technical field: [0001] A water-saving device is mainly used in water heaters. Background technique: [0002] At present, water heaters are generally installed outdoors or indoors in a safer place, most of which are far away from the user's water terminal, and generally have multiple user water terminals in different locations, so it is necessary to lay Long hot water outlet pipe. Every time the water heater is in use, the cold water left in the pipeline after the last use must be discharged before hot water can flow out, and after use, the remaining water will be left in the pipeline to cool down and be discharged when it is used next time . If the user lacks water-saving awareness, this part of cold water will be wasted in vain, or the user has a certain water-saving awareness, but it is also troublesome to deal with. If the pipeline is long, the amount of water that is wasted each time will add up to a very large amount. However, the popularization and utilization rate...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the waste of remaining water in the existing water heater pipes, the present invention provides a water-saving water heater device, which can not only prevent cold water from flowing out of the user terminal with a long hot water outlet pipe when it is turned on, but drain it from the pipe. Hot water will come out quickly after the air is exhausted, and the remaining water in the pipeline can automatically flow back into the water storage tank when the machine is turned off and can be reused next time
