[specific embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
Shown in accompanying drawing 1 and accompanying drawing 2; The utility model comprises: small-sized displacement type water heater 1, magnetic valve and control device; Said magnetic valve is a three-way magnetic valve 2, and said small-sized displacement type water heater links to each other with hot water feeding pipe road 3 through three-way magnetic valve, and said hot water feeding pipe road connects central water-feed 11; The other end of said three-way magnetic valve connects water supply pipe 4; The three-way magnetic valve place is provided with temperature sensor I 5 on the said hot water feeding pipe road, and electrical heating elements 6 and temperature sensor II7 are installed on the said small-sized displacement type water heater, and said temperature sensor I, three-way magnetic valve, electrical heating elements and temperature sensor II are through the line connection control device.Said control device comprises master controller 8 and high temperature protection device 9, and said high temperature protection device connects temperature sensor I, three-way magnetic valve, electrical heating elements and temperature sensor II through master controller.
In the utility model, small-sized displacement type water heater is installed near the water supply pipe place, and this small-sized displacement type water heater links to each other through three-way magnetic valve with the hot water feeding pipe road, links to each other with water supply pipe through three-way magnetic valve again simultaneously.Be provided with check valve 10 between three-way magnetic valve and the temperature sensor I on the said hot water feeding pipe road.Said water supply pipe is provided with and mixes water valve 12, and this mixed water valve connects hot water feeding pipe road and water supply pipe.Said three-way magnetic valve is a mechanical type threeway heating power expansion valve.
The operation principle of the utility model is: at first after system's fills with water, small-sized displacement type water heater is heated to the water in the container temperature and the insulation of setting automatically; When terminal the opening of water with water valve; Central authorities' water-feed hot water flows out, and all pushes the cold water in hot water feeding pipe road to end, this moment temperature sensor I to detect temperature be cold water temperature; Promptly the temperature of this mensuration is lower than the predefined temperature of temperature sensor I; As being lower than 45 ℃, it is logical that three-way magnetic valve is in three-way magnetic valve water inlet 21-three-way magnetic valve delivery port 2 23, is pushed to terminal cold water and gets into small-sized displacement type water heater through small-sized displacement type water heater water inlet A; The pre-warmed water of small-sized displacement type water heater is ejected, and hot water flow to the terminal water valve of using from small-sized displacement type water heater water outlet B; Because the distance between water supply pipe and the small-sized displacement type water heater is very short, the water end will use hot water after the general second, has realized the function of instant-heating.After the cold water along with the hot water feeding pipe road is constantly pushed to small-sized displacement type water heater; Filled with the hot water that comes out from central water-feed in the hot water feeding pipe road; Temperature sensor I detected temperature and reached predefined temperature this moment, and as more than 45 ℃ the time, master controller provides instruction; The three-way magnetic valve switching-over is logical for three-way magnetic valve water inlet 21-three-way magnetic valve delivery port 1; Three-way magnetic valve water inlet 21-three-way magnetic valve delivery port 2 23 closes, thereby central heater has guaranteed the terminal continuity with the supply of water valve hot water of water directly to the terminal water valve supply water of water.And this moment; The cold water that gets into small-sized displacement type water heater finds that this temperature is lower than the predefined temperature of temperature sensor II, can also be provided with the concrete boundary that is lower than this design temperature here after temperature sensor II identification; As be lower than 5 ℃ of this design temperatures; Promptly working as the predefined temperature of temperature sensor II is 60 ℃～65 ℃, and when the detected temperature of temperature sensor II was lower than 55 ℃～60 ℃, then master controller was supplied power to electrical heating elements; Small-sized displacement type water heater gets into automatic heat tracing state, thereby is that task is prepared hot water down.According to this principle, can take the terminal water temperature intelligent controller of multistage a plurality of the utility model described central authorities water supply for large-scale central water supply commercial system, thereby realize the function of plug and play.
In the utility model; Compare with traditional cycle heat radiation loss each household about 30-40MJ/24H of family; Adopt the radiation loss of the terminal water temperature intelligent controller of the utility model described central authorities water supply to be merely 5.4MJ/24H, can save cycle heat radiation loss at least 80% greatly with the precious intrinsic energy consumption compute in a little kitchen.
The utility model does not receive the restriction of above-mentioned embodiment; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
