ABSTRACT:
A hair curler includes an apertured cylindrical shell about which hair to be curled is wound. Mounted within the shell are two semicylindrical mounting components which donfine between themselves a plurality of spaced apart pill-shaped PTC resistor bodies. The engaging surfaces of the pill-shaped resistor bodies and of the semicylindrical mounting components are complementary and cylindrical, to establish good electrical and thermal contact between the engaging surface portions. Voltage is applied across the two semicylindrical mounting components, causing the generation of heat within the PTC resistor bodies. The PTC action of the latter causes an automatic limiting of temperature, preventing damage to hair. The generated heat is transmitted to a heating plate in contact with a wick extending into a water container. Water evaporates from the wick and steam passes into the interior of the apertured cylindrical shell, out through the apertures thereof, and into contact with the hair wound around the curler.
