Hand-held hair dryer with vibration and noise control

Described is a quiet hand-held hair dryer with configuration and component combinations for making the hair dryer exceptionally quiet and efficient. The hair dryer includes a housing having a lower handle portion and an upper body portion separated by an air-directing wall. A large impeller moves air downward from a large top air inlet and passes it outward through a side air outlet in a hair drying stream. An electric motor is mounted in the handle housing adjacent its bottom and is connected in driving relation with the impeller by a long vertical shaft. The motor is mounted in a rubber casing permitting cooling air flow and minimizing vibration to the housing; and the upper end of the shaft is stabilized by a bearing mounted in a rubber housing for the same purpose. The configuration of the described hair dryer permits high air flow with relatively low motor speeds.
