ABSTRACT:
An axial flow hair dryer comprises a main housing and an outer duct secured to the main housing with the axis of the outer duct coincident with the axis of the main housing and with the axial air outlet of the main housing disposed within the outer duct to form an annular air intake between the main housing and the outer duct. A first fan stage and first stator stage are disposed within the main housing and a second fan stage and second stator stage are disposed within the outer duct. A handle depending from the main housing holds a motor that is mounted using vibration-absorbing material to inhibit the propagation of noise generated by the motor. A flexible shaft connects the motor to a drive shaft that carries both fan stages. Resistance heating wires are wrapped around the vanes of the first stator stage to heat the air flowing through the hair dryer.
