An axial flow hair dryer (10) comprises a main housing (20) and an outer duct (24) secured thereto with outer duct (24) axis coincident with the main housing (20) axis and with the axial air outlet (27) of the main housing (20) disposed within the outer duct (24) to form an annular air intake (26) between the main housing (20) and the outer duct (24). A first fan stage (100) and first stator stage (150) are disposed within the main housing (20) and a second fan stage (200) and second stator stage (250) disposed within the outer duct (24). A handle depending from the main housing (20) holds a motor (36) mounted using vibration-absorbing material to inhibit the propagation of noise generated by the motor (36). Resistance heating wires (70) are wrapped around the vanes of the first stator stage (150) to heat the air flowing through the air dryer (10).

Ce sèche-cheveux (10) à flux axial comporte un carter principal (20) et un conduit extérieur (24) solidaire du carter principal. Le conduit extérieur (24) est dans l'axe du carter principal (20), l'orifice (27) d'air axial du carter principal (20) donnant dans le conduit extérieur (24) de façon à former, entre le carter principal (20) et le conduit extérieur (24), une admission d'air annulaire (26). Un premier étage de turbine (100) et un premier étage de stator (150) sont disposés à l'intérieur du carter principal (20), un deuxième étage de turbine (200) et un deuxième étage de stator (250) étant disposés à l'intérieur du conduit extérieur (24). Une poignée partant du carter principal (20) renferme un moteur (36) qui est monté avec un matériau anti-vibrations permettant d'éviter la propagation du bruit produit par le moteur (36). Les fils (70) des résistances chauffantes sont enroulés autour des pales du premier étage de stator (150) de façon à réchauffer l'air traversant le sèche-cheveux (10).
