PROBLEM TO BE SOLVED: To solve a problem that the impairing of effects of the air of high oxygen concentration and the indoor air quality-improved air such as an antioxidant substance discharged from an indoor machine, caused by the contamination of the air sucked into the indoor machine and the attachment of molds generated in the condensation water generated during the cooling operation to an air trunk in the indoor machine. SOLUTION: This air conditioner comprising a device for releasing the oxygen-enriched air or the air including antioxidant substance to the entire room, has the indoor machine and an outdoor machine, and comprises a wind direction changing device mounted near an outlet of the air trunk of the indoor machine for changing the blowing-out direction by rotating a plurality of plate members, and a device for releasing at least one of the oxygen-enriched substance and a substance having antioxidant effect to a suction port of the indoor machine, the air trunk or a blowout port. The plurality of plate-shaped members of the wind direction changing device are movable in the direction of an end of the air trunk by demounting the plate members from the air trunk or releasing a fixed state of the wind direction changing device, whereby the air trunk can be opened.
