(57) 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).
