ABSTRACT:
An electronic air cleaner, in which an air inlet, a mechanical prefilter, an electrifying cell, an electrostatic collector cell, a chemical filter and an air outlet are arranged in the order in a casing of insulating material. The electrifying cell comprises a grounded conductive protection net located behind the mechanical prefilter, a plurality of thin-wire electrodes and a plurality of grounded conductive plates. The thin-wire electrodes are less than 50 microns in diameter and arranged in appropriate intervals at substantial rectangles with an air path from the air inlet to the air outlet. Each of the grounded conductive plates has one end attached to the protection net and backwardly extending between adjacent two of the thin-wire electrodes along the air path. The electrostatic collector cell comprises the entending parts of the grounded conductive plates and a plurality of negative high voltage conductive plates respectively connected to the thin-wire electrodes and laid between the grounded conductive plates. A direct current voltage less than 4.2 kilo-volts is applied to the negative high voltage conductive plates. An electric fan causes a flow of air from the inlet to the outlet to perform highly effective air cleaning under preventing the ozone development.
