When the gas water heater works, the gas inlet pipe is communicated with a smoke outlet pipe port of the gas water heater, condensed smoke after heat exchange enters the gas water heater, condensed water is gathered in the shallow pool and leaks into the water sealing pipe, and smoke rises along with the bent pipe and is discharged from the smoke exhaust pipe. When the condensed water in the water seal pipe is accumulated more, the condensed water overflows from the overflow pipe.

Compared with the prior art, the utility model has the advantages of it is as follows showing:

1) The water seal structure of the water seal pipe can effectively seal the smoke, and the smoke is prevented from being discharged into a room from the overflow pipe;

2) An internal and external balanced type discharge structure is formed, so that the generated condensed water can be discharged in time no matter how much, and can not be accumulated in the water seal pipe;

3) The fume extractor is provided with a reasonable buffer area, even if a large amount of condensed water is generated in a short time, the condensed water can be smoothly guided into the water seal pipe, and backflow is avoided.

The utility model discloses a further perfection is, the bottom of the pool of shallow pool with the high parallel and level of overflow pipe lower edge. Therefore, enough water can be stored in the water sealing pipe all the time, and the water sealing effect is ensured.

The utility model discloses a further perfection is, shallow pond extends the back through voltage-sharing hole and water seal pipe intercommunication through the drainage groove to balanced water seal space and atmospheric pressure keep the comdenstion water drainage smooth and easy, avoid leading to the circulation to be retarded because of inside and outside atmospheric pressure is uneven.

The utility model discloses a further perfection is, be equipped with in the water seal intraductal with the small opening below with the separate wall that keeps off that encloses of warning pipe, the bottom that encloses the wall has the intercommunicating pore. Therefore, the flow speed of the drained water can be controlled, the phenomenon of turbulent flow is avoided, and the smoothness of the drainage of the condensed water is ensured.

The utility model discloses a further perfection is, one of circular arc return bend, intake pipe or the pipe of discharging fume extends the piezometric tube. This external hose is connected to the wind pressure switch during installation, and when inside when the circulation of flue gas was not smooth and easy because of reasons such as blocking up, the wind pressure switch will detect pressure change signal and carry controlling means, and then control burner shutdown, played the safety guarantee effect.
