The operation principle of the gas heater described in the utility model embodiment is described in detail below：Work as voltage-stablizer
When pressing stable after normal work, gas heater, water heater is in normal combustion and heat exchange state, and gas heater will exchange heat
, the hot water in normal bathing temperature range be supplied to user's bathing.When voltage-stablizer failure combustion gas is straight-through, rear pressure is more than theory
Pressure value after design, crimps pressure value before nearly combustion gas afterwards, and combustion gas at this time and air stoichiometry deviation theory design load, fuel gas buring do not fill
Point, there is yellow flame, the exceeded phenomenons of CO.Simultaneously because rear pressure value increases, the flue-gas temperature meeting that fuel gas buring generates in blast tube
It drastically raises, temperature sensor 600 detects the flue-gas temperature for meeting or exceeding desired temperature, and master controller 700 controls again
Shut-off valve 230 is closed, and cuts off the combustion gas at suction nozzle 210, and water heater is just stopped.It can prevent water heater from damaging, to heat
Hydrophone plays a very good protection.And scald problem caused by can also avoiding the occurrence of bath water overheat, promotes water heater
Security performance.
It should be noted that temperature sensor 600 can need to select corresponding specification according to actually detected, such as 180 DEG C,
200 DEG C etc..So as to ensure that there is stable performance and high accuracy of detection in 600 course of work of temperature sensor, without
It is influenced by environment temperature.The utility model can also select smoke detectors to replace temperature sensor 600 according to actual needs,
But it because smoke detectors are usually semiconductor transducer, are easily influenced by ambient humidity and temperature, especially works as flue gas
When reaching certain temperature, stability is greatly affected, and easily fails.Once smoke detectors fail, then it is difficult to solve the application
The problem of voltage-stablizer fails.
In the present embodiment, the smoke exhaust mechanism 500 includes the exhaust fume collecting hood 510 docked with the heat exchanger 400 and sets

During water vapor linked valve 200, the master controller 700 is used to that the wind turbine 520 to be controlled to start.It follows that water feeding of heater and
Wind turbine 520 starts to be carried out at the same time substantially.And due to lighting a fire again after the course of work usually ventilation, the water flowing of water heater, logical
Wind turbine 520 also starts during water, thus wind turbine 520 starts before ignition, can be advance by the remaining flue gas in water heater
It empties, while flue gas is persistently discharged during burning, ensure that water heater is safe to use.Another aspect wind turbine 520 is being lighted a fire
Start before burning and also reached the requirement of anti-blocking detection, i.e., detect whether discharge flue blocks before ignition, when blocking
If, wind turbine 520 when master controller 700 receives smokeless discharge signal, then can not can stop remaining flue gas discharge in flue
It only supplies, supply water to be stopped, and send a warning.
The utility model embodiment may also include temperature controller (attached drawing is not shown), and the temperature sensor 600 is by described
Temperature controller is electrically connected with the master controller 700.The flue-gas temperature information detected is transferred to temperature control by temperature sensor 600
Device, detected real-time flue-gas temperature information is compared temperature controller with desired temperature, and determines whether feedback letter
The master controller 700 number is sent to, the master controller 700 receives to control the shut-off valve according to feedback signal is whether there is
Whether 230 close.For example, when real-time flue-gas temperature information is greater than or equal to desired temperature, temperature controller is then by feedback signal
Master controller 700 is issued, master controller 700 then controls shut-off valve 230 to close；When real-time flue-gas temperature information is set less than temperature
During value, then temperature controller does not send feedback signal to master controller 700, and master controller 700 is failure to actuate, and shut-off valve 230 stays open
State.It should be noted that the utility model can also save the temperature controller, directly received by master controller 700 described
The flue-gas temperature signal that temperature sensor 600 is sent, and the desired temperature with prestoring in it is compared, afterwards according to comparison
As a result the action of shut-off valve 230 is controlled.It should also be noted that, for the gas heater control mode there are many,
Program in it can be set according to actual needs.
Optionally, the shut-off valve 230 is solenoid valve, and solenoid valve is electrically connected by conducting wire and the master controller 700.
Solenoid valve control precision is high, and reliability and flexibility are good.
In addition, the water outlet of the water vapor linked valve 200 is connected by water inlet pipe 810 with the heat exchanger 400, it is described
The gas outlet of water vapor linked valve 200 is connected by air jet pipe 830 with the burner 300.The gas heater further includes outer
Shell 100, the water vapor linked valve 200, the burner 300, the heat exchanger 400, the exhaust fume collecting hood 510, the wind turbine
521 grade of main body is arranged in the shell 100, and the smoke evacuation connector 522 is then stretched out outside the shell 100.On the shell 100
Equipped with faucet 110, the heat exchanger 400 is connected by outlet pipe 820 with the faucet 110.
The operational process of gas heater is illustrated with reference to Fig. 2 and Fig. 3：
As shown in Fig. 2, when gas water heater working and voltage-stablizer normal work, press and stablize after gas heater, combustion gas
Water heater is in normal combustion and heat exchange state, and the flue-gas temperature of burning is less than the desired temperature of temperature controller, gas heater
Normal work.As shown in figure 3, when gas water heater working and voltage-stablizer fail when combustion gas being caused to be led directly to, rear pressure is set more than theory
Pressure value after meter, the flue-gas temperature that fuel gas buring generates in blast tube can be raised drastically, and flue-gas temperature is greater than or equal to temperature controller
Desired temperature, master controller receive temperature controller feedback signal, afterwards control shut-off valve 230 close, cut off suction nozzle 210
The combustion gas at place, and when feeding back pin without flame feedback signal, water heater is just stopped.
