Abstract: A portable electric hair dryer includes an electric heater and blower forming a load circuit energized from a pair of power feeder lines connected to a source of AC power. A zero phase-sequence current transformer is electrically coupled to the power feed lines between the connection thereof to the power source and the load circuit to serve as a current leakage detector. An electricaly conductive heater enclosure disposed within the housing of the hair dryer receives the heater and is electrically isolated from the power feed line serving as the hot line. The heater enclosure is electrically connected to the power feeder line serving as the neutral line by a ground wire extending between the heater enclosure and the point at which the zero phase-sequencing transformer is coupled to the power feeder lines to define a leakage current path between the hot line and the heater enclosure should the hair dryer be dropped in water.

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.

Abstract: A facial beauty device attainable, in addition to facial sauna effect with a heated and highly moistened atmosphere, a facial skin washing effect by means of water spray and simultaneously both facial skin tightening and massaging effects accompanying inherent cooling and spray pressure, respectively. The device is provided with a moistening means oscillating water in a reservoir within a body case at a frequency of an ultrasonic band and delivering generated mist into a hood on the case to provide a highly moistened atmosphere within the hood, means for heating the mist by passing it through an electric resistive heater or carrying it onto the hood with hot air stream heated by the heater, and means for spraying water in the reservoir or from a tank capable of automatically supplying water responsive to falling water level in the reservoir toward a face contacting opening of the hood through nozzles opened in the hood by means of a pump.

Abstract: A method of setting durable curls in hairs in which a flow of simultaneously warmed and humidified air is applied to rolled hairs. A device for performing the method comprises a base body, a stand erected on the base body preferably in a manner foldable in the base body and a hood of substantially semi-spherical shape for defining an optimum hair setting atmosphere therein and coupled rotatably to upper end of the stay, air warming and humidifying mechanism secured outside the hood adjacent mounting position thereof to the stand for blowing warmed and humidified air inside the hood preferably from ceiling to downward open edge of the hood along inner wall thereof, and means for controlling the mechanism and disposed in the base body for easy access. In an optimum structure of the device, the base body is of a disk shape complementing the circular open end of the hood, so that when the stand is folded and the hood is rotated over the base body the hood will cover the base body compactly for storing.
