Reflux water saving device for water heater

Abstract

The invention discloses a reflux water saving device for a water heater, which comprises a water storage box, a water inlet pipe of the water storage box and a water outlet pipe of the water storage box, wherein one end of the water inlet pipe of the water storage box is connected with a hot water pipe of the water heater, and the other end of the water inlet pipe of the water storage box is connected with the water storage box; one end of the water storage box is connected with a water mixing valve of the water heater, and the other end of the water outlet pipe of the water storage box is connected with the water storage box; the water inlet pipe of the water storage box and the water outlet pipe of the water storage box are both provided with control valves; or the water storage box is internally provided with a switching-out system, a floating plate system, a movable wedge system and a water valve control system, wherein the switching-off system is connected with the floating platesystem and used for pulling the floating plate system; the floating plate system drives the movable wedge system, and therefore the water inlet valve control system connected with the movable wedge system is started; in addition, the water outlet pipe of the water storage box is internally provided with a check valve. The reflux water saving device has the advantages of lower cost, capability of batch production, wide application, easiness in popularization and small energy dissipation and can be applied to hotels, communal facilities and common families and accords with the current requirements of energy saving and emission reduction.

Description

technical field [0001] The invention belongs to the field of daily necessities, and relates to a sanitary product, in particular to a water heater backflow water-saving device. Background technique [0002] Because of its ease of use, water heaters have become one of the daily life electrical equipment in hotels, public facilities and families. However, after the water heater has boiled hot water, when the hot water switch is turned on for the first time, the shower head will not immediately emit hot water, but first emit cold water, and then hot water will emerge after a period of time. In this way, during use, especially in winter, cold water splashing on the body will give people a biting cold discomfort, especially for children, pregnant women, and the elderly, the discomfort caused by this stimulation is stronger; at the same time, when using Also can increase a lot of troubles to the user in the process; What's more, most of the time, this part of water is let off for...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a water heater backflow water saving device, which solves the problem that hot water flows out only after the cold water in the water heater pipeline runs out every time the water heater is used, and this part of cold water is usually wasted

[0006] Another object of the present invention is to provide a water heater backflow water-saving device, which solves the problems of existing water-saving devices that need to provide additional power equipment (such as water pumps) and high energy consumption.
