Hair dryer
First Claim
1. In a hair-grooming implement including a housing, impeller means in said housing for creating an airflow, heating means for said airflow in said housing in cascade with said impeller means, a hollow body with at least one outlet, and a conduit extending from said housing to said body for conveying a flow of hot air to said outlet, the combination therewith of first manually operable control means for said heater means, second manually operable control means for said impeller means, link means for coupling said first and second control means together, and decoupling means for selectively deactivating said link means to enable independent setting of said first and second control means, said link means being effective to translate an adjustment of one of said control means into a compensatory adjustment of the other of said control means for maintaining a substantially constant air temperature at said outlet over a range of different flow rates.

-
2. The combination defined in claim 1 wherein said first control means is mechanically connected with said decoupling means for automatically operating same in a home position of said first control means to deactivate said link means for enabling free selection of flow rate independently of temperature.
-
3. The combination defined in claim 2 wherein said heating means is unoperated in said home position of said first control means.
-
4. The combination defined in claim 2 wherein said decoupling means comprises a spring-biased element juxtaposed with said first control means for manual displacement during displacement of said first control means from said home position into a selected operating position, release of said element in said selected operating position making said link means effective.
-
5. The combination defined in claim 4 wherein said first control means comprises a knob and said second control means comprises a pedal.
-
6. The combination defined in claim 1 wherein said conduit is a flexible hose.
-
7. An implement as defined in claim 1 wherein said housing is of part-spherical configuration.
-
8. An implement as defined in claim 1 wherein said body has a multiplicity of hair-stroking projections, said outlet being subdivided into a multiplicity of discharge apertures interspersed with said projections.
