Abstract

PURPOSE: To ensure that the starting of combustion can be prevented even on the completion of timer operation by providing an LSI clock circuit fitted in a combustion device in which a motor conducts forced draft with instantaneous service interruption holding function and providing a circuit for releasing the service interruption holding operation.
CONSTITUTION: With a push button switch 30 pushed, a terminal 20a is opened, and a transistor 28 keeps conducting until the time set on a timer. Therefore, a relay 27 is driven and contacts 27a and 27b are opened to work as a timer. A resistor 24 and a capacitor 25 constitute the service interruption holding circuit of the relay 27. On service interruption, a relay 35 is held for a predetermined time period by the charge on a capacitor 37. With the relay 35 returned after the predetermined time period, contacts 35aW35c open and the holding circuits of a relay 5, a clock circuit 20, and the relay 27 are all opened. Thus, a combustion control circuit 10 is prevented from operating to start combustion, and safety can be procured.
