Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

The invention provides a method for saving water by using the existing household equipment as the basis, which comprises a water flow switch and a water using end and is characterized in that: still include water heater, water pump, time relay module, voltage transformation rectifier, water pipe, stop valve, mix the water valve, the water heater leads to water piping connection with the water pump, install the rivers switch on the water pipe, water pump one side is provided with voltage transformation rectifier, water end one end is provided with mixes the water valve, the time relay module is connected to rivers switch, water end one end is provided with the stop valve, including following step:

s1, turning on a water using end, triggering a water flow switch to work, wherein the water flow switch gives an electric signal to a time relay module, a time relay is triggered to switch on a water pump circuit, and the time relay module starts timing;

s2, rotating the handle of the water mixing valve to a position close to the middle position for adjusting the flow of cold and hot water so that the cold and hot water pipes are communicated with each other at the water mixing valve;

s3, closing a stop valve of a water outlet at the water using end, and enabling a cold and hot water pipe between a cold and hot water pipe of the water heater and a water using point to form a closed loop under the pressure of the water pump;

s4, opening the stop valve, and adjusting the water mixing valve to a proper position to start normal use of hot water.

The working principle of the invention is as follows: when the water mixing valve at one end of the water using end is opened to discharge water in the hot water pipe, the water can flow, the water flow switch and the water heater are triggered to start, the water flow switch gives an electric signal to the time relay module, the time relay is triggered to switch on a water pump circuit, and meanwhile the time relay module starts timing. At this moment, the handle of the water mixing valve is rotated to the middle position close to the cold and hot water flow regulation, so that the cold and hot water pipes are communicated with the water mixing valve, and then the stop valve of the water outlet at the water using end is closed (the stop valve can be closed firstly, and then the water mixing valve is adjusted to the middle position, and then the stop valve is opened to trigger the water flow switch to work and then closed). At the moment, the cold and hot water pipes between the cold and hot water pipes of the water heater and the water consumption point form a closed loop under the pressure of the water pump. Therefore, water in the closed loop pipeline flows, the water heater continues to work, heated hot water reaches a water consumption point, the stop valve is opened at the moment, and the water mixing valve is adjusted to a proper position to start normal use of the hot water. And no cold water is wasted in discharge. Different time relay module times are set according to different lengths of the water-using household pipelines, the time relay module cuts off a water pump circuit after the preset time is reached, and the water pump stops working. (when the water pressure of the water using environment is lower, a time relay can be cancelled, and a water pump participates in the whole water using process.) at the moment, the water in the water heater and the pipeline continuously flows by the pressure of tap water and the water heater works. The start and stop of the water pump are jointly controlled by the water flow switch and the time relay module, the closed-loop passage is blocked when the water mixing valve is closed, and the water flow switch closes and cuts off the time relay module circuit, so that the water pump stops working. Need not to reserve the setting in advance, can open at water end direct control and stop, make its work more reliable, convenient to use avoids wasting water resource, realizes effectively economizing on water.

It should be noted that: 1. 2, when the water pressure of the water using environment is lower, the time relay can be cancelled, and the water pump participates in the whole water using process.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
