Title: Flame detecting circuit
Inventor: NUMAKURA MAKOTO
IPC: F23N5/24
Filed: 1983-03-25
Abstract: PURPOSE:To prevent the occurrence of a hazardous condition in which an ignition failure condition is erroneously decided as an ignition condition due to a disconnection trouble of a resistor and the supply of fuel continues, by a method wherein a resistor, which increases a voltage drop, is connected to the non-inversion input terminal of a comparator IC, and a resistor, which discharges the charge of a capacitor, is connected to an inversion input terminal. CONSTITUTION:Even if a resistor 18 is brought to a disconnection trouble, in case it is an ignition failure condition, the output of a comparator IC 19 is brought to a disconnecting condition through the working of a resistor 24 to stop the supply of fuel. In case a resistor 9 or 11 is brought to a disconnection trouble, a resistor 23 is added in parallelism to a capacitor 13, and thereby a current flowing out of an inversion input terminal 19b of the comparator IC 19 flows in the grounding of a circuit through the resistor 23 without charging the capacitor 13. As a result, the voltage of the inversion input terminal 19b is not increased and the output of the comparator IC 19 is brought to an OFF-state, and thereby the supply of fuel is stopped.
