Fig. 2 is the logic diagram of the control device of water-saving water heater of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail:
Embodiment:
As shown in Figure 1, the water-saving water heater of this routine utility model comprises water heater 1, feedback pipe 2, hot-water line 3, cold water pipe 4, hot-water switch 9 and cold water switch 10, wherein the water inlet of water heater 1 is connected with feedback pipe 2, delivery port is connected with hot-water line 3, cold water pipe 4 is connected with feedback pipe 2, the water outlet of hot-water line 3 is provided with hot-water switch 9 and is used for improving use hot water, be provided with bypass branch 21 on the feedback pipe 2, be provided with cold water switch 10 in bypass branch 21 and be used for improving cold water, be provided with water tank 5 on the feedback pipe 2, water tank 5 is positioned at cold water pipe 4 and the below, junction of feeding back pipe 2, be provided with the first valve 6 on the cold water pipe 4, feedback pipe 2 is connected with hot-water line and is being connected by the second valve 7 near water outlet, is provided with supercharging device 8 near the below, junction with cold water pipe 4 on the feedback pipe 2.
This routine operation principle is: form a closed-loop path by water heater 1, feedback pipe 2, hot-water line 3 and water tank 5 are communicated with by the second valve 7, when opening water heater, open supercharging device 8, thereby allow cold-water reflux heating in the water heater 1 in the hot-water line 3, slattern thereby cold water directly need not be got rid of, realized the saving of water resource.The purpose that water tank 5 is set is for whole water circulation system provides a buffer point, avoids the current can't normal circulation, when opening cold water switch 10, will be stored in wherein cold water flow out for.The purpose that supercharging device 8 is set is to provide power for whole water circulation system, because the first valve 6 acquiescences at cold water pipe 4 places are closed at this moment, original water inlet such as the running water of cold water pipe 4 of relying on provides pressure that hydraulic pressure is entered water heater, but this moment, the running water inflow can cause the circulatory system normally to move, and therefore needed a supercharging device 8 to improve power when not opening the first valve 6.It is herein water cold water normally that supercharging device 8 is arranged on benefit near the water inlet of water heater 1, allows supercharging device 8 can be in a good working environment, can effectively improve its service life.
