<p>PROBLEM TO BE SOLVED: To facilitate a maintenance of a dust collecting part such as exchange or cleaning of the dust collecting part adsorbing dust contained in outdoor air sucked by ionic wind. SOLUTION: A main body case 1 is composed of a front and a rear cases 2, 3 and the front surface of the front case 2 is covered with a front cover 19. A gutter like attaching case 33, on which a discharge wire 31 is mounted, is detachably mounted on the front cover 19. A rectangular counter electrode 33, to which a dust collecting paper 74 is adhered, is provided in the front case 2. Electric discharge is generated by impressing negative high voltage to the discharge wire 31 and positive high voltage to the counter electrode 32, outdoor air is sucked from a 1st air intake hole 20 provided on the front cover 19 by the ionic wind generated by the discharge, dust is removed by the dust collecting paper 74 and there after, the purified air is discharged to a room from a 1st air discharge hole 72. Then, when the dust collecting paper 74 is exchanged, the front cover 19 is detached from the front case 2 and at this time, since the discharge wire 31 is detached with the front cover 19, the discharge wire 31 does not interrupt the exchange of the dust collecting paper 74 attached to the front case 2 and excellent workability is attained.</p> |
