ABSTRACT:
A handheld electrically powered hair dryer includes a main outlet nozzle and secondary air outlets for producing a diffuse distribution of air. A baffle arrangement is moveable between first and second positions to selectively deflect some or all of the air from the nozzle to the secondary air outlets. The baffle arrangement consists of a flexible crown-shaped metal foil disposed on the inside of the nozzle, and a mechanism for bending the foil radially inwardly to partially or completely block the nozzle when the baffle is moved toward the second position.
