Ventilation system for household appliances, in particular for washing machines, comprising a device (1) having at least: a chamber (CG) for housing an impeller (4); a suction duct (6), through which a first fluid, in particular damp air, is sucked into said chamber (CG) by means of said impeller (4); an ejection duct (CU), through which the first fluid sucked into said chamber (CG) is expelled from it by means of said impeller (4); a first movable shuttering means (7) for obstructing the said suction duct (6) at least partially, said first shuttering means (7) being movable at least partially inside said suction duct (6); first actuating means for producing the motion of said shuttering means (7). According to the invention, after operation of said first means the first shuttering means (7) is capable of performing movements comprising at least a linear component, said linear component extending in the same axial direction of said suction duct (6). |
