Abstract
An electric hair curler comprises a handle and a barrel connected thereto for winding thereabout the hair. The barrel is provided with an electric heater for curling the hair wound on the barrel. The heater includes a plurality of resistor elements in the form of strips extending along the length of the barrel in generally parallel relationship with one another and being electrically connected in series by a corresponding number of bridging segments. The heater thus constructed is mounted on the barrel with the resistor elements thereof being exposed on the outer surface of the barrel in circumferentially spaced relationship with one another around the barrel, so that each of the resistor elements is in direct heat transfer contact with the hair to be wound on the barrel, thus greatly reducing the heat loss to assure effective heat transfer from the heater to the hair. This enables the heater to be energized by a battery or like source of relatively low current capacity to give off enough heat for curling treatment. Accordingly, the hair curler of the present invention may utilize a battery or the like as a power source for the heater, yet assuring an effective curling treatment of the hair.
