ABSTRACT:
An electronic air cleaner includes discharging electrodes for charging dust particles with a polarity, and dust collecting electrodes of an opposite value for collecting the charged dust particles. The dust collecting electrodes are moved toward and away from the discharging electrodes to compensate for changes in electric current caused by various conditions such as a build-up of dust on the dust collecting electrodes. The current change is detected by a control unit which rotates a drive screw to displace the dust collecting unit.
