Claims

[Scope of Claim for Utility Model Registration] (1) A main body installed in the ceiling and having a heat exchanger, a blower, an air suction part, and an air outlet, and a main body installed in the lower surface of the main body and discharging air from the air outlet. In a ceiling-embedded air conditioner equipped with an air outlet for blowing air into the room and a louver near the air outlet that changes the direction of the blown air, one side of the guide wall that constitutes the air outlet near the air outlet. has a partially arcuate cross-section, and this outlet air passage has a structure that gradually decreases toward the outlet, and the guide wall facing this guide wall is flat and extends in the direction of expanding the outlet with respect to the outlet air passage. The louver is formed to be bent at a predetermined angle, and the louver is pivotally supported by a rotating shaft provided parallel to the guide walls, and when rotated, its tip reaches the planar guide wall. A ceiling-mounted air conditioner characterized by its shape. (2) Claim 1 of the utility model registration, characterized in that the center of the radius of curvature of the circular arc cross section of the guide wall, which has a partially approximately circular arc cross section, coincides with the center of the rotation axis of the louver. The listed ceiling-mounted air conditioner. (3) The ceiling-embedded air conditioner according to claim 1 or 2, wherein the louver has an airfoil-like cross-sectional shape.
