Abstract
A hair dryer is provided with a high voltage generator which produces a negative DC voltage output of at least about 6 kilovolts for reducing static charges on a person's hair during hair drying. The generator can be mounted adjacent the dryer air inlet of the hair dryer housing to cool the generator with cooling air, or the generator can be mounted externally of the dryer to reduce dryer weight.
Claims12
A hair dryer, comprising:
- a tubular housing having an air inlet and an air outlet;
- a high voltage generator mounted within said tubular housing adjacent said air inlet;
- a fan unit mounted in said tubular housing between said air outlet and said high voltage generator;
- a heating coil assembly mounted in said tubular housing between said air outlet and said fan unit;
- and
- a high voltage electrode mounted in said tubular housing and connected to said high voltage generator for producing negative ions, and wherein ambient air is drawn into said tubular housing through said inlet, over said high voltage generator so as to cool said high voltage generator, around said heating coil assembly and out of said tubular housing through said air outlet.
