Abstract
PURPOSE: To avoid a state that a flame detecting circuit continues to operate even at accident such as fire extinguishing and power suspension, etc. and actuates to reignite, which is seen in the conventional equipment, by making the contact point of a flame detector to be disconnected at said accident time, to cut electric current flow to a combustion control circuit.
CONSTITUTION: If a power source switch 2 and an operating switch 3 are closed, a transistor Tr21 is turned on, the contact points 14 and 15 of a relay 6 are closed and the relay 6 is self-locked. Then a fuel supply valve 7 opens, a combustion fan 28 and an igniter 11 operate and a pilot burner is ignited. By so doing, a flame detecting circuit 9 operates, and by its output, Tr22 is turned on and a flame detector 10 operates, the contact point 15 is changed over to a normally open terminal side and a contact point 24 is closed. Therefore, a fuel supply valve 12 and a fan driving circuit 26 operate and a main burner is ignited. If a fire extinguishing or an interruption of electric current occurs in this state, the contact point 24 of the flame detector 10 is disconnected, so that electric current flow to said combustion control circuit is cut.
