Abstract:
A dust collector for collecting fine dust in air and for cleaning said air, comprising:a first friction member produced from a first substance; a second friction member produced from a second substance that is chargeable triboelectrically in a polarity different from a polarity of said first substance; a friction driving mechanism which moves one of said first and second friction members relative to a remaining one thereof, and which frictionally generates electrostatic charge, to attract said fine dust and attendantly provide clean air for a cooling function; a passage case for defining a path of said air, having an air intake port and an air exhaust port, wherein said first and second friction members are disposed between said air intake port and said air exhaust port and overlapped with one another; and a fan for flowing of said air in said passage case, wherein said first or second friction member attracts said fine dust electrostatically while said air flows in said passage case.
