Hand-held hair dryer with vibration and noise control

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;
• f. separation means for substantially separating said lower handle portion from said upper body portion;
• and
• g. first resilient means, encircling said motor and affixed to said handle portion, for minimizing sound and vibration in said handle portion from said motor;
• h. wherein said first resilient means comprises a resilient rubber-like cylindrical motor boot having an outer surface comprising mounting means, including multiple outward projections, for mounting said electric motor within said lower handle portion.

• b. separation means for substantially separating said lower handle portion from said upper body portion;
• c. air inlet means, at said top of said housing, for supplying air to said hair dryer;
• d. air outlet means, at a side of said housing, for directing said hair drying stream in a direction substantially perpendicular to the direction of flow of said air in said air inlet passage for passing air into said housing;
• e. immediately beneath said air inlet means, rotor means for blowing said air in a hair drying stream;
• f. heating means, in said air outlet passage, for heating said air;
• g. an electric motor, adjacent said bottom of said housing, connected in driving relation with said rotor means;
• and
• h. shaft means, having an upper and a lower end, for connecting said electric motor in driving relation with said rotor means;
• I. first resilient means, encircling said motor and affixed to said handle portion, for minimizing sound and vibration in said handle portion from said motor;
• j. bearing means for holding said upper end of said shaft means in fixed relation to said housing;
• and
• k. second resilient means, encircling said bearing means and affixed to said housing, for minimizing sound and vibration in said housing;
• l. wherein a said upper air inlet passage has at least as great a diameter as the diameter of a greatest sweep of said rotor means.
