Hand-held hair dryer with vibration and noise control
First Claim
1. In a quiet hand-held hair dryer, the combination comprising:
- a. a housing having a lower handle portion and an upper body portion forming upper air inlet and air outlet passages for passing air into said housing and for discharging said air in a hair drying stream, said housing having a top and a bottom;
b. air inlet means at said top of said housing, for supplying air to said hair dryer;
c. immediately beneath said air inlet means, rotor means for blowing said air in a hair drying stream;
d. an electric motor, adjacent said bottom of said housing, connected in driving relation with said rotor means;
e. shaft means, having an upper and a lower end, for connecting said electric motor in driving relation with said rotor means; and
f. first resilient means, encircling said motor and affixed to said handle portion, for minimizing sound and vibration in said handle portion from said motor.

Abstract
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.
