Gas stove with flame detection

A gas stove with flame detection electrically connected to an air drafting device and an alarm device, comprising:

• a switch module generating an ignition signal to ignite a fuel from a gas stove, and a gas stove flame generating from the fuel;
• a flame detecting module including a visible light detecting unit for detecting combustion state of the gas stove flame to generate a first light wave signal at wavelength ranging from 450 nm to 500 and a second light wave signal at wavelength ranging from 600 nm to 780 nm and,
• a processing module electrically connected to the switch module and the flame detecting module, activating the air drafting device and the alarm device when receiving both the first light wave signal and the second light wave signal or only the second light wave signal from the flame detecting module, and receiving the ignition signal from the switch module.
