摘要

A wall-mounted grille particularly for the passage of air from an air-conditioning unit toward the outside, the grille being constituted by a perimetric frame (11) inside which a series of deflecting vanes (12a, 12b, 12c, 12z) are fixed in a parallel arrangement and have a substantially concave transverse cross-section with the concavity directed upward, the vanes (12a, 12b, 12c, 12z) having, on their bottom (13), drainage openings (14) for draining rainwater toward an underlying sloping wing (15) which is interposed between the last lower deflecting vane (12a) and the lower edge (16) of the frame (11).
