Abstract
THE INVENTION RELATES TO A RADIAL FAN WHEEL PREFERABLY ON AN ELECTRIC MOTOR (10), ESPECIALLY THE ELECTRIC MOTOR OF A VACUUM CLEANER, HAVING A FAN WHEEL DISC (8) PROVIDED WITH BLADES (8) WHICH PREFERABLY CURVE ALONG THEIR LENGTH, HAVING A CURVED OUTER SIDE (3) AND A CURVED INNER SIDE (4), THE FAN WHEEL DISC (8) BEING PROVIDED WITH AIR FLOW OPENINGS (6). IN ORDER TO EFFECT A REDUCTION IN THE NOISE WHICH IS GENERATED, THE INVENTION PROPOSES THAT THE AIR FLOW OPENINGS (6) BE ASSOCIATED WITH A BLADE (2) ON THE OUTWARDLY CURVED SIDE (3) THEREOF.(FIG. 4)
