Patent number: 10816238Abstract: An indoor unit of an air-conditioning apparatus eliminates a possibility of condensation on a front panel without deteriorating a quality of design. In an off state, an auxiliary air-directing plate is positioned above an up-down air-directing plate inside an air outlet such that a free end of the auxiliary air-directing plate opposite from one end of the auxiliary air-directing plate fixed to a rotating shaft is positioned closer to a rear surface of a casing than is the rotating shaft. In an on state, the auxiliary air-directing plate is rotated in a direction from the rear surface to a front surface of the casing, and the free end is protruded from the air outlet to an outside of the casing.Type: GrantFiled: December 1, 2015Date of Patent: October 27, 2020Assignee: Mitsubishi Electric CorporationInventors: Yusuke Adachi, Takahiro Shishido, Mitsuhiro Shirota, Takashi Ikeda, Yoshinori Tanikawa

Patent number: 5758719Abstract: The invention relates to a separation-type air conditioner capable of increasing the heat exchanging area of a compact indoor unit and of effecting high-performance heat exchange, and particularly employable as a high-performance yet compact indoor unit whose height is low. A front heat exchanger having a configuration in which an upper edge portion and a lower edge portion are respectively made to recede is disposed in an indoor unit. In addition, a rear heat exchanger separate from the front heat exchanger is disposed on the rear surface side of the front heat exchanger. Consequently, it is possible to increase the heat exchanging area in an indoor unit having the same height, and improve the heat exchanging capacity.Type: GrantFiled: April 19, 1996Date of Patent: June 2, 1998Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Makoto Yoshihashi, Akira Takamori, Natsuko Nishigaki, Motoo Sano, Motoshige Satou, Yoshinori Tanikawa
