Abstract
PURPOSE: To provide a timer circuit capable of being set and released during an operation of any mode and nevertheless having a simple constitution in an automatic operation of a room heater by means of a timer.
CONSTITUTION: A timer device is consisting of a contact S1, controlling a control circuit except for a tiemr, a contact S2, controlling a supply of fuel, and a contact S3, controlling the operation of the timer itself. A timing for the timer device is constituted, as indicated in a figure, so that the contacts S2, S3 are cooperating under the same consition and are operating to effect opposing operations relative to the contact S1, controlling the control circuit except for the timer, upon setting and finishing of the timer. A room heater is constituted so that a D.C. electric source circuit 5 is operated by closing an electric source switch S4-1, a fan 2 for combustion is operated by a safety start circuit 7 which closes an output contact S8 when the device is kept at a safety temperature, and firing thereof is effected by a igniting heater 4 when a fuel feeding valve 10 is operated by an output of a fuel controlling circuit 9.
