Beneficial effect of the present invention is as follows: (1) has thoroughly solved with the cold water problem of putting earlier before the hot water in the heat supply water pipe, has saved water resource; (2) preferably resolve the antifreeze problem of heat supply water pipe in winter.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
By embodiment shown in Figure 1 as can be known, it includes heat supply water pipe 6, return pipe 4, circulating pump 10, is output as water flow switch 9 (for commercially available prod), magnetic valve 3, temperature sensor 8, automatic controller 2, the housing 7 of pulse signal; The bottom in the heat storage water tank 11 is stretched in the upper end of described heat supply water pipe 6, on described heat supply water pipe 6 heat supply water valve 5 is installed; The upper end of described return pipe 4 stretches to the place, top of heat storage water tank 11, and the other end of described return pipe 4 is connected with the lower end of heat supply water pipe 6, and described magnetic valve 3 is housed on described return pipe 4; Described housing 7 is fixed on the bottom surface of heat storage water tank 11, described circulating pump 10, water flow switch 9, temperature sensor 8 is housed successively being positioned on the described heat supply water pipe 6 of described housing 7; Described automatic controller 2 is housed in described housing 7; Described automatic controller 2 is connected with described circulating pump 10, water flow switch 9, temperature sensor 8, magnetic valve 3 by lead respectively.
Present embodiment also includes battery 1, solar panel 12; Described solar panel 3 is contained on the described heat storage water tank 11, and described battery 1 is contained in the described housing 7; Described solar panel 12 is given described battery 1 charging by described automatic controller 2, and described battery 1 is respectively described water flow switch 9, circulating pump 10, magnetic valve 3 power supplies by automatic controller 2.
In the present embodiment, between described housing 7 and circulating pump 10, water flow switch 9, temperature sensor 8, be provided with heat-insulation layer.
Operation principle of the present invention is as follows: when using hot water, at first heat supply water valve 5 is opened, it is closed once flowing out when water at once and (its objective is water flow switch 9 work that make, allow its output pulse signal), this moment, water flow switch 9 output pulse signals were given automatic controller 2, automatic controller 2 starts magnetic valve 3 work on circulating pump 10 and the return pipe 4, cold water in the heat supply water pipe 6 is looped back heat storage water tank 11 by return pipe 4, magnetic valve 3 on circulating pump 10 and the return pipe 4 is worked behind the setting-up time (being generally 1-2 minute), stop its work by automatic controller 2, at this moment open heat supply water valve 5 instant-heating and outlet hots again.
It is most common failure that the solar water heater water supply line in winter of northern area freezes stifled, and reason is that the water in the pipeline does not flow for a long time.When temperature sensor 8 reaches design temperature, it outputs signal to automatic controller 2, automatic controller 2 starts circulating pump 10 and magnetic valve 3, cold water in the heat supply water pipe 6 is looped back heat storage water tank by return pipe 4, circulating pump 10 and magnetic valve 3 are worked to setting-up time and are promptly quit work, and working so repeatedly to reach antifreezing effect.
