<P>PROBLEM TO BE SOLVED: To enhance the ability of a flexible duct to convey air ions. <P>SOLUTION: An opening 1 in the flexible duct 10 of an air-conditioning system having an air ion generator is electrically connected to a metallic connection opening 9 in a device, and the inner core 4 of the duct 10 is grounded. The charge of the air ions being conveyed will not be neutralized unless the inner core 4 is charged, and the air ions are not decreased. If an end processing material 5 made of insulating material covers the end faces and the inner and outer peripheral surfaces of the opening 1, both openings can be electrically connected to each other via an earth wire 6 extending from the inner core 4 and pulled out through the space between the end processing material 5 and the opening 1. An electrically conductive layer 5a may be provided on the end processing material 5, brought into contact with the connection opening 9, and electrically connected to the inner core 4 by a through pin 8. The conductive layer 5a may be folded back over the inner peripheral surface of the opening 1 to facilitate the connection of the both. <P>COPYRIGHT: (C)2007,JPO&INPIT |
