Title:
ION BLOWER AND PROJECTOR
Document Type and Number:
Japanese Patent JP2013201846
Kind Code:
A
Abstract:

To provide an ion blower that can achieve a long life while sufficiently securing a static pressure of an ion wind.

An ion blower 4 comprises: a first blowing section 6 that has a first electrode 6A for generating ions M and a second electrode 6B having a potential set higher than that of the first electrode 6A and generates an ion wind W directed from the first electrode 6A toward the second electrode 6B; and a second blowing section 7 that has a third electrode 7A for generating the ions M and a fourth electrode 7B having a potential set higher than that of the third electrode 7A and generates the ion wind W directed from the third electrode 7A toward the fourth electrode 7B. The first and second blowing sections 6 and 7 are disposed such that the first through fourth electrodes 6A, 6B, 7A, and 7B are disposed side by side in order of the first through fourth electrodes 6A, 6B, 7A, and 7B in a circulation direction of the ion wind W. The potential of the third electrode 7A is set to a potential not less than the potential of the second electrode 6B.
