Title: Ventilation grille with water discharge
Inventor: LEX ERNST DIPL ING
IPC: F24F13/08
Filed: 1988-04-02
Abstract: There exists a ventilation grille, for an air flow directed from the outside inwards, in which an outer and a middle row 6, 8 of lamellae 7, 9 are situated with a gap between them and in which the lamellae 11 of an inner row 10 are located opposite the lamellae 7 of the outer row 6. In this arrangement, it is desired to improve the water discharge of the ventilation grille. This is achieved in that each lamella 7 of the outer row 6 forms a longitudinally extending channel 23 at the outer edge. By means of the channels of the outer lamellae, collected water is discharged downwards at the outer lamellae and prevented from penetrating into the ventilation grille. <IMAGE>
