ABSTRACT:
A hair dryer including a blower for selectively generating a current of air at various flow rates, a thermostatically controlled electrical heater for selectively heating the current of air at various heat generation rates and a switch mode switch and associated circuitry for selectively activating the heater and the blower and including a three position switch actuated by a single button and having a first normal mode position wherein the heater is activated to generate heat at a first heating rate and the blower is activated to generate a current of air having a first flow rate, a second cool-shot mode position wherein the heater is activated to generate heat at a second heating rate which is less than the first heat rate and the blower means is activated to generate a current of air having a second flow rate which is less than the first flow rate and a third hot-shot mode position whereupon the heater is activated to generate heat at a third heating rate which is equal to or greater than the first heat rate and the blower is activated to generate a current of air having a third flow rate which is lower than the first flow rate. A temperature switch independent of the mode switch provides additional control of the heater output level. An independent power switch is provided for concurrently controlling the heater and blower to vary the magnitudes of the heating rates and flow rates in a correlated manner in said first, second and third modes.
