ELECTROSTATIC DUST COLLECTOR

摘要

The present invention provides an electrostatic dust collector and the like which inhibit ozone generation and have a thin charging unit. An electrostatic dust collector (1), according to the present invention, comprises: a charging unit (10) having a high voltage electrode (11), to which a high voltage is supplied from a high voltage generating circuit (40), and an opposing electrode (12), which is formed opposite from the high voltage electrode (11) and to which a reference voltage is supplied from the high voltage generating circuit (40), generating discharging between the high voltage electrode (11) and the opposing electrode (12), and thus charging floating fine particles; and a dust collecting unit (20) disposed on the lower side in the ventilation direction of the charging unit (10) and for collecting the fine particles that have been charged by means of the charging unit (10).
