Claims

[Scope of utility model registration request]

In an ignition device in which the ignition operation and flame detection operation proceed when the start switch is turned on, the ignition device starts when a start signal is input, the main valve opens when the start signal is input, and the main valve enters a detection state when the start signal is input. A flame detection device detects the presence or absence of a flame in a fire burner, a counter that counts the number of operations of the ignition device and outputs a raw signal only when multiple operation signals are input, and a negative output of the counter and a flame detection device. A first AND circuit or an equivalent circuit to which the negative output of the detection device is input, a pre-purge timer started by the output of the circuit, and a second AND circuit to which the output of the counter and the negative output of the flame detection device are input. The pre-purge timer is composed of a circuit or an equivalent circuit, a main valve closing means into which the output of the second AND circuit or its equivalent circuit is input, and a main valve that opens according to the output of the flame detection device. An ignition system for gas appliances that inputs the output to the ignition device.
