AIR PURIFIER

摘要

PURPOSE:To purify air by automatically detecting dust or pollen in air to rotate a suction fan and collecting the dust or pollen in air by a filter. CONSTITUTION:Dust in air is collected by a filter 10 and a suction fan is rotated by a motor 12. High voltage is generated by a high voltage generating means 13 and the space applying the high voltage from the high voltage generating means 13 is provided to a discharge electrode 14. Further, a change of the voltage or current value of the aforementioned high voltage is detected by a contamination detection means 15 to detect the contamination of air. The motor 12 is controlled on the basis of the signal from the contamination detection means 15 by a motor control means 16. That is, the dust or pollen in air is automatically detected to rotate the suction fan and the dust or pollen in air is collected by filter to make it possible to purify air.
