US 2014/0190511 A1 · DUST REMOVER

Abstract

A dust remover which comprises a power supply and an electrode applied with voltage by said power supply. The dust attached to the object of dust removal is removed therefrom by bringing the electrode into contact with the object of dust removal or approaching toward the object of dust removal. The object of dust removal is a conductor and/or an insulator. The voltage applied to said electrode is a pulsed voltage of plus and minus or an AC voltage of plus and minus. Or the voltage is a DC voltage having the same polarity with that of electricity with which the dust is charged, or the voltage is a DC voltage having an opposite polarity to that of electricity with which the dust is charged. The object of dust removal includes at least a ball for “Pachinko”, a car body, a printed board, a metal box or a part thereof, a frame for glasses, a plastic lens, a plastic box or a part thereof, a fiber, a wood, a paper box or a part thereof.

Dependent claims

A method of removing dust charged with static electrical charges of one polarity so as to be electrostatically attached to an object for dust removal comprising:

(a) providing a repelling electrode charged with one polarity, the same as that of the static charges of dust electrostatically attached to the object, near or in contact with a first side of the object in order to cause charges of the one polarity to be generated on a second side of the object to which the dust is attached to be repelled from the object,
(b) providing an attractive electrode charged with an opposite polarity in proximity to the second side of the object in order to attract dust away from the second side of the object, and
(c) providing a suction device in proximity to the second side of the object positioned around or adjacent to the attractive electrode in order to suction away dust repelled by the one polarity of the repelling electrode and attracted by the opposite polarity of the attracting electrode, thereby obtaining an effective detachment of dust and suctioning away of the dust for removal from the object.
