Method for purifying inside of room
In order to remove a pathogenic effect of a microorganism in a room or a work space in a short period of time, an ion diffusing apparatus, which includes an ion generator ( 17, 18 ) for generating positive ions each including H + (H 2 O) m and negative ions each including O 2 − (H 2 O) n , where m and n are arbitrary integers, and a blower for delivering the positive ions and the negative ions, which are generated from the ion generator ( 17 ), from a blowout opening, is operated to widely distribute, with a high concentration, the positive ions and the negative ions in the room.
1. 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 − (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.
2. A method of purifying an inside of a room according to claim 1 , wherein a concentration of the positive ions and the negative ions in air of the inside of the room is set to 7,000 per cm 3 or higher.
3. A method of purifying an inside of a room according to claim 1 , wherein a concentration of the positive ions and the negative ions in air of the inside of the room is set to 30,000 per cm 3 or higher.
4. A method of purifying an inside of a room according to claim 1 , wherein a concentration of the positive ions and the negative ions in air of the inside of the room is set to 50,000 per cm 3 or higher.
5. A method of purifying an inside of a room according to claim 1 comprising a sectioning portion for sectioning between the positive ion generation portion and the negative ion generation portion along an air current.
6. A method of purifying an inside of a room according to claim 5 , wherein a generation amount of the positive ions generated from the positive ion generation portion and a generation amount of the negative ions generated from the negative ion generation portion are each 1.5 million per cm 3 or higher at a position distanced 50 cm from the positive ion generation portion and the negative ion generation portion.
7. A method of purifying an inside of a room according to claim 1 , wherein a generation amount of the positive ions generated from the positive ion generation portion and a generation amount of the negative ions generated from the negative ion generation portion are each 1.5 million per cm 3 or higher at a position distanced 50 cm from the positive ion generation portion and the negative ion generation portion.
