Patent ID: 8685328

Claim:
A method of purifying an inside of a room, comprising operating an ion diffusing apparatus so as to deliver an air current from the blowout opening in a substantially horizontal direction so that an upper portion of the air current flows with a higher blowout speed compared to a blowout speed of a lower portion of the air current in order to widely distribute, with a high concentration, positive ions and negative ions in a room or a work space, whereby a pathogenic effect is removed from an airborne microorganism and/or an adhering microorganism, the ion diffusing apparatus comprising: an ion generator having, a positive ion generation portion for generating positive ions each comprising H + (H 2 O) m , where m is an arbitrary integer, and a negative ion generation portion for generating negative ions each comprising O 2 âˆ’ (H 2 O) n , where n is an arbitrary integer; a blower for delivering the positive ions and the negative ions, which are generated from the ion generator, from a blowout opening; a duct connecting between the blowout opening and the blower; a plurality of vertically-separated paths formed inside the duct by dividing an interior of the duct in a vertical direction; and laterally-separated paths formed inside the duct by further dividing the vertically-separated paths, wherein the positive ion generation portion and the negative ion generation portion are disposed in such orientations as to be spaced apart from each other in a direction intersecting a flow direction such that the positive ions generated by the positive ion generation portion flow through one of a pair of neighboring paths among the laterally-separated paths and the negative ions generated by the negative ion generation portion flow through the other of the neighboring paths.
