  • Patent number: 10816238
    Abstract: 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.
