Patent number: 9726384Abstract: An air conditioner includes a main unit having an enclosure defining an air outlet. The enclosure contains a heat exchanger generating a cool air or a warm air forming airflow running out of the air outlet. A pair of fan units are disposed on the opposite sides of the air outlet. The fan units are configured to suck a room air and to blow the room air. The airflow of the room air can be utilized to control the direction and/or movement of the airflow of the cool air or the warm air. The cool air or the warm air can be conveyed to desired locations.Type: GrantFiled: April 29, 2013Date of Patent: August 8, 2017Assignee: FUJITSU GENERAL LIMITEDInventors: Ritsushi Taira, Shinji Sugiyama, Kenji Haruyama, Syun Iwano, Fumiaki Tanaka

Patent number: 6338382Abstract: In an air conditioner equipped with an air cleaner, a front panel is provided with three air inlets: a first air inlet located on the front face of the front panel, a second air inlet located on the top face thereof, and a third air inlet located therebetween. Each of the first and second air inlets has an opening/closing unit including louvers, and an air cleaner is arranged on the inside of the third air inlet. At the time of cooling/heating operation and at the time of dehumidifying operation, the first and second air inlets are opened and closed by the opening/closing unit, by which the amount of air passing through the air cleaner is changed, thereby utilizing the air cleaner effectively.Type: GrantFiled: August 17, 2000Date of Patent: January 15, 2002Assignee: Fujitsu General LimitedInventors: Tomomi Takahashi, Shinji Sugiyama, Ritsushi Taira, Shunsuke Nakashima, Makoto Yanagida
