Silencer for Drying Appliance and Silent Hair Dryer

A silencer (1) for an appliance comprising at least one casing (30) comprising an inlet end (33), an outlet end (31) and at least one motor (M) for rotatably driving at least one turbine (T) for sucking in air via at least one admission orifice (330) at the level of the inlet end (33) upstream of the turbine (T) having a diameter (Da) and expelling said air downstream of the turbine via at least one outlet orifice (310) at the level of the outlet end (31), characterised in that said silencer comprises at least one chamber (10) mounted substantially tightly upstream of the admission orifice (330) and having an inlet orifice (110) having a diameter (De) for aspiration of air upstream of the chamber (10), said chamber having a diameter (Dc) being greater than the diameter (Da) of the admission orifice (330) and the diameter (De) of the inlet orifice (110), the chamber having a length (L) and the diameter (Dc) being of such a size so as to define a volume tuned as a function of the sound frequencies to be attenuated by the silencer (1).
