    Abstract: The ducted type air conditioner provided by the present disclosure, including: a shell, an air opening being formed in the shell; a fan, rotatably arranged in the shell; and a water-receiving disk, arranged in the shell and located between the fan and the air opening; in the case that the air opening serves as an air inlet, the orientation of an air-absorbing opening of the fan inclines upwards relative to a horizontal direction; or in the case that the air opening serves as an air outlet, the orientation of an exhaust opening of the fan inclines upwards relative to a horizontal direction. According to the ducted type air conditioner provided by the present disclosure, the air-absorbing opening or exhaust opening of the fan inclines upwards relative to the horizontal direction when facing the water-receiving disk, that is, the air opening of the fan inclines away from water-receiving disk when facing the water-receiving disk, so that the influence of the water-receiving disk on the air volume of the fan is effectively reduced, the flowability of the airflow in the shell is ensured, and the heat exchange efficiency of the ducted type air conditioner is improved.

    Abstract: This ceiling-embedded air conditioner comprises: a motor having an output shaft rotatable about an axis; a turbo fan attached to the output shaft; and a heat exchanger that surrounds the turbo fan from the outer peripheral side and has a dimension in the axial direction which is larger than the dimension of the outlet flow path of the turbo fan in the axial direction. The turbo fan has: a main plate that is attached to the output shaft and has a disk shape about the axis; a shroud that is axially spaced apart from the main plate; an array of a plurality of circumferentially spaced-apart main blades provided across the shroud and the main plate; and a guide member having a guide surface that faces the shroud side while protruding circumferentially from a pressure surface, which is the surface of the main blade facing the forward side of the output shaft in the rotational direction.

    Abstract: The present invention relates to an air conditioner.
    The air conditioner according to an embodiment of the present invention includes: a base panel having an inlet formed in one side thereof, and an outlet formed in another side thereof, a variable panel disposed under the base panel and changed in shape to open and close the inlet and the outlet; and a driving device disposed on the base panel and changing a shape of the variable panel, thereby allowing the variable panel to cover the entire lower surface of base panel. In addition, the variable panel may open and close the inlet and the outlet. The variable panel includes: a fixed part disposed between the inlet and the outlet, and fixed in position vertically relative to the base panel; a cover part spaced apart from the fixed part and disposed at a lower side of the inlet or the outlet; and a variable part disposed between the fixed part and the cover part, and changing an inclination angle of the cover part.
