  • Hair curler steamer with PTC heater and thermally isolated cold and hot water reservoirs
    Patent number: 5761378
    Abstract: A steamer for a steamable hair curler includes thermally isolated cold and hot water reservoirs. Water in the hot water reservoir is heated by a PTC heater. The volumetric capacity of the hot water reservoir is very small. The PTC heater has an intrinsic cutoff temperature high enough to boil water in the hot water reservoir and low enough to prevent deterioration of any component parts of the steamer, even in the absence of water in the hot water reservoir. Due to the thermal isolation of the reservoirs, water in the cold water reservoir is not substantially heated during normal operation of the steamer.
