IPC: F23N5/24
Filed: 1989-12-20
Abstract: PURPOSE:To enable a power failure safety function part to be formed in a miniature size and at a low cost by a method wherein an off-position sensing means is provided, when an on-position of a switch member is detected, a burner is ignited only when it is detected that the switch member is in an off-position just before it. CONSTITUTION:An off-position sensing circuit 50 is a circuit arranged only for starting an operation when an operation switch 33 is changed from its off-position to its on- position in order to assure a safety while the power failure occurs. In the case that the operation switch 33 is placed at its off-position, an electrical charging circuit is formed by a resistor 52 and a capacitor 53 at an output part of a bridge diode 51 connected to an off-contact point 33c connected to a movable contact point 33a. A light emitting diode 54a of a photo-coupler 54 is connected to a capacitor 53 through a resistor 55. A control circuit 31 may detect that the operation switch 33 is placed at its off-position only when the operation switch 33 is changed from its off-position to its on-position and in turn in the case that a supplying of electrical power is stopped due to a power failure during the operation and subsequently the power supplying is recovered, the fact that the operation switch 33 is kept at its off-position is not detected.
