  • Patent number: 7478640
    Abstract: A hair iron can give hair a sufficient amount of negative ions. The hair iron has a grip, and a hair-care section connected to the grip, having a heater for generating heat to hair for hair dressing. Further, it has a negative ion generator which generates negative ions due to discharge around an electrode therein to emit them toward hair held by the hair-care section. The hair-care section has a bar-like shape, and the heater is fixed to an outer surface of the bar-like shape. Then, by winding hair to the hair care section in the hair iron, hair dressing can be performed efficiently.

  • Patent number: 7165341
    Abstract: A hair dryer is provided, which includes a housing having an air outlet, fan disposed in the housing, a pair of air flow channels extending toward the air outlet in the housing, a partition wall for separating the channels from each other, heater disposed in only one of the channels, and a minus-ion generator disposed in the other channel. The partition wall is formed by a tubular member, which is disposed in the housing such that one of the channels is provided by an inner space of the tubular member, and the other channel is provided by a clearance between an inner surface of the housing and an outer surface of the tubular member. Therefore, it is possible to simultaneously provide a cold air flow with minus ions and a hot air flow from the air outlet, and thereby efficiently perform hair styling.
