Technical field
The present invention relates to a kind of water heaters, more particularly, to a kind of heating start-up system of water heater.
Background technique
The water heater of household includes instant heating type tap, electric heater and electric heating drinking machine etc..The heating starting of water heater
System includes the heating chamber equipped with heating tube and the hydraulic pressure chamber equipped with float switch, and heating tube is conducted by elastic contact blade realization
Or it is electrically cut off.When opening hot water shelves, the intracavitary water inlet of hydraulic pressure, water flow makes float switch float, and float switch touches elastic contact blade
Realize conducting for heating tube.When hot water shelves are closed, the intracavitary no water inlet of hydraulic pressure, float switch sinks, and elastic contact blade separation is real
Existing heating tube is electrically cut off.
If the reasons such as blocking when impurity gathers depotition cock being caused not to be discharged, and always on hot water shelves, that is to say, that outer
The tap water in portion gives always hydraulic pressure chamber to supply water, and because hydraulic pressure reason is maintained at floating state, this can make in heating chamber float switch
Heating tube continuous heating, the water in heating chamber can be constantly in heated condition, eventually dryout heating chamber until heating tube is burnt
It is disconnected, allow water heater to scrap, there are such situations for the instant heating type tap of about 3-5% at present.Even more serious situation meeting
It is that heating chamber is detonated because hot barometric pressure is excessive, this can bring serious security risk.
In view of this, the heating starting that those skilled in the art try to develop a kind of heater that can solve drawbacks described above is opened
It closes.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind in the case where heating shelves unlatching, tap not being discharged,

Heating chamber is entered with after the first apopore.
Further preferred embodiment of the invention are as follows: the main body includes interlude and first end and the second end,
First gum cover covers on the first end, and the second gum cover covers on the second end.
Further preferred embodiment of the invention are as follows: in the case where there is streamflow regime, the first gum cover is in compressive state；Anhydrous
When stream, the first gum cover, which applies a downward active force to piston, moves down piston.
Further preferred embodiment of the invention are as follows: the end A of the piston is located above the end B of piston.
Another subject matter: water heater, including heating start-up system.
Compared with prior art, it is an advantage of the invention that air equalizer opening makes hydraulic pressure chamber and ambient atmosphere connection, in hydraulic pressure
When chamber is not intake, that is, when there is water in the intracavitary portion of hydraulic pressure but water does not flow, the pressure of water and the pressure of atmosphere make piston
Reach self-balancing, it is mobile to the opposite direction of water flow that elastomeric element promotes piston, so that piston be made to leave elastic contact blade, then will
The electrical circuit of heating tube disconnects.
After the hot water shelves of water heater are opened, but when faucet outlet is not discharged because of blocking, electrothermal tube can be cut off immediately
Power supply, prevent the ponding in heating chamber from being dryouied；Because the intracavitary water of hydraulic pressure does not just flow when tap is not discharged,
Water flow drives the active force of piston to be eliminated in this way, and elastomeric element moves piston round about, to ensure that piston and elasticity touch
Piece does not contact, and cuts off the electric power supply of electrothermal tube, prevents the dry combustion method of electrothermal tube.
