  • Hair drier
    Patent number: 6367162
    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.
