Abstract
A kind of hot water machine automatic backflow apparatus disclosed in this utility model, including boiler, water intaking valve, ejector and storage tank, described boiler is provided with heat-generating pipe, water inlet and outlet, by ejector by water intaking valve, storage tank couples together with boiler, when water intaking valve is opened, current flow into boiler through ejector, produce negative pressure in bypass ports simultaneously thus the water in storage tank is sucked in boiler, when water intaking valve quits work, boiler is anhydrous to be supplemented into, now, storage tank is connected with boiler, the water of boiler is back in storage tank, final storage tank maintains an equal level with the liquid level of boiler, so liquid level of boiler is reduced, water expanded by heating is avoided to go out from outlet water clock, do not affect the use of user, structure is practical reliable.
Description
Technical field
This utility model relates to water reflux, a kind of automatic backflow apparatus being applied to hot water machine.
Background technology
Existing hot water machine generally uses single cisten mechanism, is supplied water water tank by water inlet pipe, is provided with in water tank
For adding the heat-generating pipe of hot water, when heating after water tank is full of water, water body can expanded by heating so that water in water tank from
Outlet overflows, and dripping phenomenon occurs, affects the use of user.Prior art use reflux be typically the water of water clock
Being recycled to water tank, this type of reflux structure is complicated, relatively costly, and current are easily contaminated, and safety and sanitation can not get protecting
Barrier.
Utility model content
In order to solve the problem that prior art exists, a kind of hot water machine automatic backflow apparatus that this utility model provides, knot
Structure is the most practical reliably.
To achieve these goals, this utility model be the technical scheme is that
A kind of hot water machine automatic backflow apparatus, including boiler and water intaking valve, described boiler is provided with heat-generating pipe, water inlet
And outlet, also including ejector and storage tank, the water inlet end of described ejector is connected with water intaking valve, going out of described ejector
Water end (W.E.) is connected with the water inlet of boiler, and the bypass ports of described ejector is connected with storage tank, such storage tank and boiler
Be connected formation backflow water route, and when water intaking valve quits work, the water in boiler can be back to storage tank, the liquid level of boiler
Can decline, it is to avoid in boiler, water level is too high.
Preferably, described ejector is Venturi tube ejector.
Preferably, described water inlet is also associated with drain valve.
Preferably, described water intaking valve is electromagnetic valve.
The beneficial effects of the utility model: water intaking valve, storage tank are connected with boiler by this reflux by ejector
Getting up, when water intaking valve is opened, current flow into boiler through ejector, produce negative pressure thus by storage tank in bypass ports simultaneously
Interior water sucks in boiler, and when water intaking valve quits work, boiler is anhydrous to be supplemented into, now, and storage tank and boiler
Being connected, the water of boiler is back in storage tank, and final storage tank maintains an equal level with the liquid level of boiler, such boiler
Liquid level is reduced, it is to avoid water expanded by heating and go out from outlet water clock, do not affect the use of user, structure practicality can
Lean on.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model provide a kind of hot water machine automatic backflow apparatus, including boiler 1, water intaking valve 3,
Ejector 4 and storage tank 2, boiler 1 is provided with heat-generating pipe 6, water inlet 11 and outlet 12, and wherein, water inlet 11 is arranged on heat
The bottom of water tank 1, outlet 12 is arranged on the top of boiler 2, and the water inlet end of ejector 4 is connected with water intaking valve 3, ejector 4
Water side be connected with the water inlet 11 of boiler 1, the bypass ports of ejector 4 is connected with storage tank 2.During installation, by water storage
Case 2 arranges the residing height height greater than or equal to boiler 1, so ensures boiler 1 and the liquid of storage tank 2 after water backflow
Face height can maintain an equal level.
The ejector 4 used in embodiment is Venturi tube ejector, and water intaking valve 3 is electromagnetic valve.Additionally at water inlet 11
Place is also associated with drain valve 5, when the water in hot water machine is not drunk, discharges the water in boiler 1 by drain valve 5,
So advantageously ensure that the clean hygiene of drinking water.
As it is shown in figure 1, during work, the external feed pipe of water intaking valve 3, water intaking valve 3 opens, and current are through Venturi tube ejector
4 enter boiler 1, produce negative pressure in bypass ports simultaneously thus are also sucked in boiler 1 by the water in storage tank 2, work as hot water
After case 1 fills water, water intaking valve 3 quits work, and boiler 1 is anhydrous to be supplemented into, and liquid level rests at outlet 12, such as figure
Middle location A horizontal plane.Now, storage tank 2 is connected with boiler 1, and the water of boiler 1 is back in storage tank 2, final water storage
Case 2 maintains an equal level with the liquid level of boiler 1, and the liquid level of such boiler 1 is reduced, and reserves water and add in making boiler 1
The volume of thermal expansion, it is to avoid water is gone out from outlet 12 water clock because of expanded by heating, solves the problem that hot water machine drips.
The above, preferred embodiment the most of the present utility model, this utility model is not limited to above-mentioned enforcement
The structure of mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to guarantor of the present utility model
Protect scope.
