Patent ID: 7356943

Claim:
An automatic Hair dryer wherein a heating element is controlled by the moisture content of the hair, said Hair dryer comprising: a hand held body and a comb having a plurality of forwardly extending teeth with forward and intermediate hair engaging areas and a rear solid area fixed to said body; a heating element and a fan disposed within said body and adapted to blow air across said heating element and into an individual's hair; a moisture sensor including a plurality of probes disposed between a first plurality of said forwardly extending teeth and a second plurality of forwardly extending teeth with one of said plurality of forwardly extending teeth on each side of said plurality of probes, said probes extending from said rear area and into said intermediate area, but short of said forward area so that said probes do not come into contact with an individual's scalp; a source of 120/240 V A.C. electrical power for energizing said fan and said heating element and a source of 12 V D.C. electrical energy for energizing said moisture sensor; and electrical circuit means including a first power switch for connecting said fan to said source of 120/240 V A.C. power when said automatic dryer is turned on and a second power switch for connecting said heating element to said source of 120/240 V A.C. power when said moisture sensor is contacted by wet hair and which includes a delay circuit so that the heating element continues to operate for short periods of time when said comb is out of contact with an individual's hair, an amplifier for amplifying a signal from said moisture sensor to thereby turn said electrical power on or off and wherein said source of 12V D.C. is energized by a step down transformer connected to said source of 120/240V A.C.
