An air conditioner includes: an air blower configured to take air from an inlet, and to blow the air from an outlet; a filter configured to purify the air; a first chamber and a second chamber taking the air purified by the filter; a humidification filter provided in the second chamber, and humidifying the air taken into the second chamber; and a divider opening and closing an opening that provides communication between the first chamber and the second chamber, and adjusting a volume of the air taken from the first chamber into the second chamber. The air taken from the first chamber into the second chamber and/or the air taken into the second chamber is blown from the outlet.

Each of first to fourth needle-like electrodes is arranged such that a direction of extension thereof is parallel, and generates ions by discharge. Through a space, a gas for conveying the ions generated by the first to fourth needle-like electrodes flows. Needle tips of the first needle-like electrode and the second needle-like electrode protrude from a first wall surface that forms the space, are spaced apart from each other, and are arranged in line in the space. Needle tips of the third needle-like electrode and the fourth needle-like electrode protrude from a second wall surface that forms the space and faces the first wall surface, are spaced apart from each other, and are arranged in line in the space. The first needle-like electrode and the fourth needle-like electrode generate positive ions, and the second needle-like electrode and the third needle-like electrode generate negative ions.

Ion generation apparatus and electric equipment

A discharge device capable of maintaining a stable discharge performance even in a highly humid environment or an atmospheric environment containing salt includes a discharge electrode discharging when a voltage is applied thereto, a substrate supporting the discharge electrode, an induction electrode arranged apart from the discharge electrode, and an insulator enclosing all of the substrate and the induction electrode. The discharge electrode has a root portion supported by the substrate, a pointed end protruding from a surface of the insulator, and a taper portion tapering from the root portion toward the pointed end. An outer peripheral surface of the root portion is made of a material having an ionization tendency lower than that of hydrogen.
