Abstract (en)
[origin: EP0905455A1] An outdoor unit for use in an air conditioner has a propeller fan (2) disposed in a casing (1), and an outlet grille (4) disposed on an outlet side of the propeller fan (2). The outlet grille (4) has a square outlet opening (8) and has a plurality of blades (5) disposed in parallel with one another at given intervals in the outlet opening (8). With respect to a plane (P) which intersects with lines extending along lengths of the blades (5) at a given angle (θ) in a rotational direction of the fan and which includes the central axis of the fan (2), a difference exists between an inlet angle ( alpha A) of portions (5A) of the blades (5) positioned in an area (C1) on one side of the plane (P) and an inlet angle ( alpha B) of portions (5B) of the blades (5) positioned in an area (C2) on the other side of the plane (P). <IMAGE>
