Flameout protection device with emergency mode

The invention discloses a flameout protection device with an emergency mode, relates to a commercial stove, and provides the scheme aiming at the problem that in the prior art, the whole stove fails only due to the failure of kindling. The igniter is electrically connected with the MCU control unit; the MCU control unit is provided with a normal mode and an emergency mode; when the MCU control unit is in the normal mode, the MCU control unit further detects the state of the main gas switch when detecting that the starting frequency of the kindling switch in a preset time period is greater than a threshold value, and enters an emergency mode if the main gas switch is in a closed state; and when the MCU is in the emergency mode, the electromagnetic valve is opened, so that the main gas circuit is conducted to enter emergency work. The device has the advantages that the emergency mode is started only when the main gas switch is not turned on, so that the gas use safety is ensured. The whole stove cannot be compl
