Description
Technical field
The utility model relates to a kind of water-saving device of water heater of improvement, and particularly a kind of solar energy water saving fixtures of instant-heating, belong to heater technical field.
Background technology
At present, the water heater that market is sold is divided into two kinds substantially: one is solar energy type, and another kind is electrothermal.But no matter be any water heater, inevitably cold water is had in the pipeline be connected with tap, this cold water is called as " the invalid hot water before use ", often drained in vain during use, especially cold season has been arrived, the water that this mode is wasted can be more, are unfavorable for the saving to water resource.For this phenomenon, market is proposed various immediately heating water heater, this water heater nothing but by strengthening the power of electro-heat equipment, or utilizes various pipeline to extend the cool water heating time, thus flows out hot water.But effect is unsatisfactory.In addition, the water heater also had is provided with a gear pump between outlet pipe and water inlet pipe, and the water part flowed out through outlet pipe will flow into water heater heating by water inlet pipe again by this pump, thus reach the effect of instant-heating.But this water heater during operation pump works all the time, be also a kind of loss to pump, and shunting hot water, be also unfavorable for enough hot-water supplies.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of structure simple, easy for installation, prevent hot water to run off and the water-saving device of water heater of the instant-heating in water recovery apparatus service life can be extended.
The utility model is realized by following technical scheme:
A kind of water-saving device of water heater of instant-heating, it comprises water heater body and flowing water Valve, access tributary pipeline in pipeline between water heater and flowing water Valve, the branch line other end connects the water inlet end of water heater, in branch line, access booster pump and magnetic valve, magnetic valve is controlled by temperature sensor;
In branch line, set up return water tank and control section, described control section comprises magnetic force buoy, relay, temperature sensor, single-chip microcomputer, the second tongue tube and the first tongue tube; The control coil of described second tongue tube, the first tongue tube and relay is serially connected, and the first normally opened contact of relay controls the break-make of booster pump, and the second normally opened contact of relay is attempted by the two ends of the second tongue tube.
The water-saving device of water heater of above-mentioned instant-heating, be positioned at the side of return water tank described communicating pipe, its inside is provided with magnetic force buoy; Described communicating pipe, upper end was provided with the second tongue tube, and lower end is provided with the first tongue tube.
The water-saving device of water heater of above-mentioned instant-heating, described return water tank is located between booster pump and magnetic valve.
The utility model is by the temperature sensor in control system, and detect the water flow temperature in water pipe, temperature signal is transferred to relay, if water flow temperature does not reach setting value, namely magnetic valve is opened, and cold water is back in return water tank by magnetic valve.If after water flow temperature reaches setting value, then closed electromagnetic valve, current can flow out from flowing water Valve, have effectively achieved water heater open-and-heating, water-saving effect.For preventing continuous firing from causing damage to booster pump, when the water in return water tank is stored into a certain amount of time, the magnetic force buoy in communicating pipe (being equivalent to water gage) floats, and the second tongue tube is communicated with, and booster pump is started working; When after water level decreasing, magnetic force buoy makes the normally-closed contact of the first tongue tube disconnect, and cuts off booster pump work, like this, only just makes booster pump work when return water tank water is full, effectively reduces the number of times that booster pump starts, extend its service life.The utility model structure is simple, only need add appropriate section of the present utility model on original basis.It is easy for installation, structure is simple, has saved and has used water.

Detailed description of the invention
Referring to Fig. 1 and Fig. 2, the water inlet pipe of water heater body 1 and water outlet pipe part are respectively equipped with booster pump 5 and temperature sensor T, the water that water heater flows out, through the measurement of temperature sensor T, the open and close of Controlling solenoid valve 3, when temperature does not reach settings (settings set by single-chip microcomputer), temperature sensor T magnetic valve 3 is opened, current flow directly into return water tank 2, until when temperature reaches settings, magnetic valve 3 cuts out, and hot water flows out from flowing water Valve 7, achieves the effect of water heater open-and-heating.In addition, the utility model has set up return water tank 2 and control section, and return water tank 2 is between magnetic valve 3 and booster pump 5, and its side is provided with communicating pipe 4, is provided with magnet buoy 6 in communicating pipe.Described first tongue tube GJ1 is normally closed switch, and when the water level of return water tank is in low water level time, under the magnetic action of magnetic force buoy, the first tongue tube GJ1 disconnects; Water within communicating pipe 4, gradually storage full after, magnetic force buoy floats to the upper end of communicating pipe 4, it with often open the second tongue tube GJ2 under magnetic action, the second tongue tube GJ2 is closed, circuit ON, booster pump is started working; Water level decreasing within communicating pipe 4, magnetic force buoy 6 retreats to when centre, and under the effect of the normally opened contact J-1 of relay J, booster pump works on, until after magnetic force buoy falls back on water gage small end, circuit disconnects, and booster pump quits work.The utility model, structure is simple, easy to operate, and only need be installed on water heater when using, and can use without the need to too much changing.
Control of the present utility model is completed by single-chip microcomputer, and single-chip microcomputer can adopt 80C51, and its control circuit adopts common circuit, repeats no more herein.
