Abstract
The invention relates to a water heater without outflow of cold water. The water outlet end of a water heater 1 is connected with a water temperature sensor 6 and a water outlet 8 sequentially; a three-way valve 7 is arranged between the water temperature sensor 6 and the water outlet 8; the inlet end of the three-way valve 7 is connected with the water temperature sensor 6; the normally open end 71 of the three-way valve 7 is connected between a water inlet switch 6 and a water flow switch 3; the normally closed end 72 of the three-way valve 7 is connected with the water outlet 8; and the input end of a controller 9 is connected with the water flow switch 3, a pressure switch 4 and the water temperature sensor 6, and the output end of the controller 9 is connected with a water pump 5 and the three-way valve 7. Before the water temperature reaches a preset temperature under the control action of the controller 9, water flow enters the water heater 1 constantly under the action of the water pump 5, is heated circularly and outflows until the water temperature reaches the preset temperature, so water waste is prevented.
Description
Technical field
The present invention relates to a kind of water heater that does not go out cold water, belong to the optimisation technique of water heater.
Background technology
Daily water heater before reaching predetermined water temperature, needs a period of time, and the cold water of Pai Chuing all has been wasted usually during this period of time.Under the serious day by day overall situation of global lack of water, treasure water and be our everyone obligation.
Therefore, need to seek a kind of water heater that can not go out cold water, the water of Liu Chuing is exactly the water of predetermined water temperature at the beginning.
Summary of the invention
The purpose of this invention is to provide a kind of water heater that can not go out cold water, the water of Liu Chuing is exactly the water of predetermined water temperature at the beginning.
Technical scheme of the present invention is: a kind of water heater that does not go out cold water, by water heater 1, water inlet switch 2, water flow switch 3, hydraulic pressure switch 4, water pump 5, water temperature inductor 6, triple valve 7, delivery port 8, controller 9 is formed, water inlet switch 2, water flow switch 3, hydraulic pressure switch 4 and water pump 5 are connected to the inlet end of water heater 1 in turn by water pipe, the water outlet end of water heater 1 and water temperature inductor 6, delivery port 8 connects in turn, a triple valve 7 is set between water temperature inductor 6 and delivery port 8, the arrival end of triple valve 7 is connected with water temperature inductor 6, the Chang Kaiduan 71 of triple valve 7 is connected between water inlet switch 6 and the water flow switch 3, and normal-closed end 72 is connected with delivery port 8.
The input of controller 9 is connected with water flow switch 3, pressure switch 4, water temperature inductor 6, and output is connected with water pump 5, triple valve 7.
The invention has the beneficial effects as follows:
1, by the control action of controller, before water temperature reached predefined temperature, current constantly entered water heater circulation heating under the effect of water pump, reach predefined temperature until water temperature and just flow out, and have avoided the waste of water.
Description of drawings:
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a main TV structure schematic diagram of the present invention.
Among the figure 1, water heater, 2, water inlet switch, 3, water flow switch, 4, hydraulic pressure switch, 5, water pump, 6, the water temperature inductor, 7, triple valve, 71, Chang Kaiduan, 72, normal-closed end, 8, delivery port, 9, controller.
The specific embodiment
As shown in Figure 1, a kind of water heater that does not go out cold water, by water heater 1, water inlet switch 2, water flow switch 3, hydraulic pressure switch 4, water pump 5, water temperature inductor 6, triple valve 7, delivery port 8, controller 9 is formed, water inlet switch 2, water flow switch 3, hydraulic pressure switch 4 and water pump 5 are connected to the inlet end of water heater 1 in turn by water pipe, the water outlet end of water heater 1 and water temperature inductor 6, delivery port 8 connects in turn, a triple valve 7 is set between water temperature inductor 6 and delivery port 8, the arrival end of triple valve 7 is connected with water temperature inductor 6, the Chang Kaiduan 71 of triple valve 7 is connected between water inlet switch 6 and the water flow switch 3, and normal-closed end 72 is connected with delivery port 8.
The input of controller 9 is connected with water flow switch 3, pressure switch 4, water temperature inductor 6, and output is connected with water pump 5, triple valve 7.
During work, open water inlet switch 2, current flow through water flow switch 3 and hydraulic pressure switch 4, controller 9 has detected current, start water pump 5 work, current are continuously introduced to water heater 1 and are heated, the water temperature of flowing through then inductor 6, water temperature inductor 6 sends current water temperature data to controller 9, if controller 9 judges that water temperature is lower than predefined temperature value, just do not open the normal-closed end 72 of triple valve 7, water is by the Chang Kaiduan 71 of triple valve 7, under the effect of water pump 5, flow to water heater 1 heating once more, so move in circles, detect water temperature until controller 9 and reach predefined temperature value, open the normal-closed end 72 of triple valve 7, hot water flows out from delivery port 8.
The foregoing description only is to be used for interpretation purposes of the present invention, and is not to be limitation of the present invention, and those skilled in the art in essential scope of the present invention, make various variations or alternative, also should belong to protection category of the present invention.
