Claims

[Scope of utility model registration request]

A starter circuit is inserted in parallel with a first switch that is linked to the opening operation of the gas cock, and a second switch that is linked to the ignition operation of the igniter and turns off when the ignition is completed. A flame rond circuit connected to a flame rond that lowers the resistance value, a flame current amplification circuit that reverses when flame current is generated in the circuit, an alarm control circuit, a delay circuit, a differentiation circuit, an alarm drive circuit. Furthermore, the open/close contact of the second switch is also inserted into the flame current amplification circuit, and as the flame that acts on the flame rond is generated, the flame current amplification circuit, alarm control circuit, delay circuit, differentiation circuit, and alarm drive are connected. A gas ignition alarm device characterized by sequentially controlling circuits and driving an alarm for a certain period of time after ignition.
