<P>PROBLEM TO BE SOLVED: To provide an ion generator operable to send out positive ions and negatively-charged water fine particles from two circulation channels, which is arranged so that even in a case where the positive ions and the negatively-charged water fine particles are significantly different in life, the balance of positive and negative polarities in the air can be kept for a long time by making the amount of the short-life positive ions sent out larger than that of the long-life negatively-charged water fine particles. <P>SOLUTION: The ion generator comprises: a blower 3 for sending out air; a pair of circulation channels 21 and 22 for dividing the air sent out by the blower 3 into two air flows, and leading the air flows in the same direction to send out the air flows to the outside; an ion generating part 4 provided on one circulation channel for generating positive ions only by means of corona discharge; an ion generating part 5 provided on the other circulation channel for generating negatively-charged water fine particles by means of electrostatic atomization phenomenon; and a throttle part 27 provided on the one circulation channel 21 for making the air flow running through the one circulation channel 21 faster than the air flow running through the other circulation channel 22 in velocity. <P>COPYRIGHT: (C)2013,JPO&INPIT |
