PURPOSE:To reduce electric power consumption without effecting a constant detecting operation such as the detection of oxygen lacking condition or the like, by a method wherein detecting results from the group of sensors are taken into the title controller through time sharing method while the results are processed in accordance with respective detecting factors. CONSTITUTION:The title controller is constituted so as to effect detecting operations such as the voltage check of a battery 1 or the detection of the condition of lack of oxygen, for example, through one minute interval time sharing method. Respective comparators 12, 13 are operated through time sharing method whereby the consumption of the battery 1 can be reduced and the life of the same can be prolonged. When a heater 3 is conducted, the voltage of the battery 1 drops (0.6V for example) temporarily, however, the check of a battery voltage is not effected in this case and an LED is constituted so as not to be flashed by a malfunction due to the voltage drop. When a deodorizing motor 15 is operated during ignition or combustion, flame is drawn into the lower part of a combustion tube and there is possibility of igniting kerosine or the like, however, an ignition ON and OF switch Sa is connected to the deodorizing motor 15 through an NPN type transistor Q9, therefore, the deodorizing motor 15 will never be operated during igniting and burning. |
