Abstract
PURPOSE: To display an air pollution value based upon the variation modulus of a detected ion current corresponding to a concn. of a pollution particle in a supplied polluted air by detecting a part of the ion current in a detecting electrode of an electron charge part of an electric dust collector.
CONSTITUTION: In the electric dust collector 1 in the air purifier, corona discharge in generated between a discharge electrode 2A and a ground electrode 2B to which high voltage is applied by a power source 3 and the polluted air induced to a direction shown by an arrow by an air blower 5 in purified and discharged as purified air. The meter 1 of the air purification degree consist of a detecting part 4, an amplifier part 11 and a DC ammeter 10. In the detecting part 4, the detecting electrode 4A is provided to an inflow side of an air stream so as to be faced against the discharge electrode 2A of the electric dust collector. When the polluted air is flowed in, impedance in a corona electric field is increased and current passed to the detecting electrode 4A is reduced. This reduction rate is amplified by the amplifier 9 and inputted to the ammeter 10 and, by the scale thereof, the air pollution degree is displayed.
