Patent ID: 8625252

Claim:
An ion diffusing apparatus that diffuses positive ions and negative ions generated by plasma discharge into a room, the ion diffusing apparatus comprises: a fan that generates an air flow for exhaling air, which is inhaled from an inlet, from an outlet into the room via a flow passage that is formed in the apparatus; an ion generating apparatus that includes a positive ion generating portion and a negative ion generating portion; and supplies positive ions generated from the positive ion generating portion and negative ions generated from the negative ion generating portion into the air flowing through the flow passage; and an ion generating apparatus housing portion that houses the ion generating apparatus so that an ion generating surface of the ion generating apparatus matches with a flow surface of the ion generating apparatus which is composed of a lower lateral wind-direction plate that forms a lower wall surface of the flow passage, exposing the ion generating surface to the flow passage surface to form a portion of the flow surface; wherein the ion generating apparatus is able to be inserted and pulled out from an insertion opening that is formed through a side of the outlet, the ion generating apparatus is formed as an ion generating cartridge that includes an ion generator that has the positive ion generating portion and the negative ion generating portion, the ion generating cartridge houses the ion generator and unitarily includes: an insertion guide portion; a position guide portion; and a lever member that engages with an engagement portion disposed in the ion generating apparatus housing portion of the apparatus main body to fix the position of the cartridge; wherein a structure is employed, in which the ion generating apparatus is inserted from the insertion opening into the ion generating apparatus housing portion via the insertion guide portion and the position guide portion; and fixes the ion generating apparatus in such a posture that the ion generating surface is matched with the flow passage via the position guide portion and the lever member, and the ion generating cartridge is freely mountable and demountable into and from the ion generating apparatus housing portion.
