Gas hob common flameout protection fault

Gas hob common flameout protection malfunction, the use of gas cooker we all know is often used equipment, basic daily use, so do you know what is the protection of extinguishing, what do you have


The gas cooker now has a stalling protection. Because the state is mandatory. In general, there are two types of flameout protection.

1, thermocouple extinguishing protection: the use of physical properties of metal, belonging to the temperature difference type induction, flameout protection action by temperature induction control. When the temperature is lower than the specified temperature, the gas source is cut off immediately. It is an immediate reaction, and the general extinguishing time is about 5 to 10 seconds.

2, ion induction quenching: using the photoelectric properties of the flame, when the flame deviates from the induction pin, it will immediately make a judgement in 0. seconds, and cut off the gas source in 5 to 8 seconds.


The greatest advantage of thermocouple extinguishing is to cut off the success rate of the gas source, the disadvantage is that the time is not fast enough; although the reaction is quick, if there is a natural wind to temporarily blow the flame away from the induction needle, it will also cause the solenoid valve to cut off the gas source. Whether the delay intelligent judgment is true or not. Therefore, the ion induction flameout protection technology is more suitable for gas water heaters (closed ambient combustion).

There are two ways to protect gas cooker from extinction.
