AIR ION CONVEYANCE SYSTEM

PROBLEM TO BE SOLVED: To stably carry air ions containing negative ions and positive ions while keeping an effective concentration of the air ions. SOLUTION: The air ion conveyance system comprises an air conveyance means 11 blowing and conveying air; and an air ion generation means 2 making the air conveyed by the conveyance means 1 to negative ions or positive ions or to air ions containing both the ions. This system further comprises a conductive structure for keeping conductivity through a passage for conveying the air. Specifically, in the conductive structure, at least a portion with which the conveyed air contacts is formed of a conductive metallic material or carbon resin material. A conductive member 3 connected to another conductive part is provided in a nonconductive part. Consequently, since electrification of the passage for conveying air ions is prevented, the air ions can be stably conveyed while keeping the effective concentration. COPYRIGHT: (C)2007,JPO&INPIT
