Abstract: In the present invention, winding units (19) as a stator (23) are fixedly mounted in a cylindrical housing (1). A rotor (29) is provided on vanes (26) for supplying wind. The rotor (29) is disposed to surround the stator (23), thereby forming a brushless motor (30) that provides a hair direr having low noise level and lighter construction. The rotor has a sufficiently larger dimension in a direction of flow of wind than the stator (23). The stator (23) and rotor (28) are positioned relative to each other such that the center of the stator (23) in the direction of flow of wind is at the same position as the center of the rotor (29) in the direction of flow of wind. Thus, even if the rotor (29) moves slightly in the direction of flow of wind when the rotor (29) is rotating, the torque will not change significantly.

Abstract: In one embodiment a blow dryer includes a barrel having an opening. A deflector, having an aperture, positioned within or substantially within the barrel. The hand-held blow dryer can be utilized in at least a first or open mode in which air flow is directed through the barrel opening of the barrel, and a final or fully deflecting mode. Thus, in the fully deflecting mode most of the air is deflected by the deflector so as to diffuse the airflow. Additionally, the shape of the deflector allows the airflow to be maintained while the deflector is in any position, thus, allowing the airflow to flow past the heating coils in the barrel so that potential overheating of the blow dryer is reduced. In another embodiment, a gap is provided between two flaps which comprise the deflector so as to achieve the same result. In still another embodiment, rings are provided around the circumference of a barrel having holes in the barrel. The rings diffuse the air emanating out of the holes and also guide the hair for styling.
