PURPOSE:To improve the easiness of operation and prevent erroneous operations due to noises by stopping the operation of an air cleaner and blower fan during the time in which an ignitor acts when the air cleaner and combustion are operated by interlinking continuously from the state of stopping or single opera tion of the air cleaner. CONSTITUTION:A control section 3 receives an instruction signal from an operation switch 1 to operate or stop a combustion section 4, air cleaner 6, and blower fan 5 together and it receives instruction signal from the air cleaner switch 2 to operate or stop the air cleaner 6 and blower fan 5. Here, in the period in which the ignitor 9 of the combustion section 4 operates, the air cleaner 6 and blower fan 5 are stopped regardless of the state of the air cleaner switch. With this arrangement, it is possible to improve the easiness of operation and reduce noises generated by the simultaneous operation of the air cleaner and ignitor. |
