Aerodynamic element for an air guide apparatus of an extraction hood for household use, which is equipped with this aerodynamic element air guidance apparatus and with this air guidance apparatus extraction hood is equipped for domestic use
Aerodynamic element (1) for an air guidance apparatus (2) an extraction hood for domestic use, comprising a plurality of spokes (12) with distances between them, wherein said aerodynamic element (1) a central region (10) and an outer edge (11), each spoke (12) on a curved path (13) starting from the central region (10) to the outer edge (11) of the hole, wherein each spoke (12) an at least partially around the curved path (13) curved profile (14) and said profile (14) in any one of its orthogonally with respect to the curved path (13), one face end of cross sections (14a), one of the end face (14a) opposite rear side (14b), an underside (14c) and one of the underside (14c) opposite upper side (14d) forms, wherein the ratio between the end face (14a) or the rear side (14b) and the underside (14c) or the upper side (14d) extending from the middle region (10) to the outer edge (11) is varied toward, characterized in that each spoke (12) a front region (15) with a first curvature along the curved path (13) from the central region (10) to the outer edge (11) and a rear region (16) with a second curvature along the curved path (13) from the central region (10) to the outer edge (11), wherein the front region (15) and the rear region (16) in each case on the upper side (14d) and the underside (14c) of each spoke (12) a first (17) and a second function of the discontinuous line (18) form.
