Hair dryer comprises electric motor contained in a streamlined shell defining with an inner surface of the housing an air channel with annular cross section continuously and gradually widening, from the turbine towards the heating element
The hair dryer (1) has a housing (2) consisting of a suction case (3) containing a centrifuge fan including a turbine (7) associated with an electric motor (8). The housing is connected to a blow nozzle (9) containing a heating element (10). The electric motor (8) is at least contained in a streamlined shell (14) defining with an inner surface (21) of the housing (2) an air channel with annular cross section continuously and gradually widening, from the turbine (7) or from a specific distance (23) from the turbine, towards the heating element (10). The shell (14) is formed by a cylindrical casing extended by a tapered or substantially profiled end part towards the heating element, and the casing external diameter is equal or substantially equal to the turbine external diameter.
