Abstract

PURPOSE:To sensitively respond to the generation of pollution by raising the detection sensibility for pollution at the time of standby of air cleaner operation. CONSTITUTION:The heater 5a for a pollution detecting sensor 5 is impressed with electricity for a specified time by a CPU 10 controlling a transistor (TR) 17 to turn on. Thus, the pollution detecting sensor 5 is set in the correctly operating state and the detection of air pollution is started. When the air pollution is not detected, that is, the output of a voltage of a comparator 16 is 'H', the output 02 of the CPU 10 is 'L'. As a result, TR 17 is turned off so as to be sensitive even for a small fluctuation of the pollution detecting sensor 5. Consequently, the resistance value of the pollution detecting sensor 5 is reduced even in the case of small air pollution and the reversed input potential is raised to become higher than the reference potential as nonreversed input potential, and the output of the voltage comparator 16 is turned 'L', which sends the signal showing 'air is polluted' to the CPU 10.
