A hair drier having the capability of efficiently supplying hot air and minus ions from different outlets is provided. This hair drier has a hollow housing with an air suction inlet and an air outlet. In the housing, a fan and a heater are disposed in an air-flow channel formed between the air suction inlet and the air outlet. The air sucked in the housing by the fan is heated by the heater, and then ejected from the air outlet. The housing also has an ion-flow channel formed as an independent flow channel from the air-flow channel, and an ion outlet provided at a different position from the air outlet to eject minus ions generated by the minus ion generator. The minus ion generator is disposed in the ion-flow channel.

A hand-held hair dryer which includes a negative ion generator and a corona discharge operating between a pin in the ion chamber and the grid at the outlet of the barrel for injecting a continuous supply of ions into the heated air stream. The hair dryer has an infrared on/off sensor switch which automatically activates the device when picked up by the user and a separate cooling switch to lower the heat level while maintaining the same air volume. The hair dryer includes a self-contained cord retractor which employs a fail-safe microswitch preventing operation unless electric cord is fully unreeled. Separate push button controls and readouts covered by a single membrane are attached on the body of the unit to control speed and ionizer function.

The dryer includes in its programmable control circuit a microprocessor to which are connected at least a temperature sensor, a static pressure sensor, a motor revolution sensor, a ion generator, a resistor battery with its selector switches in series, and the respective power circuits of the motor and the air heater aforesaid, in which, in order to optimize the processing route, said microprocessor, after the dryer is turned on and the operating values of parameters, establishes the initial operating configuration at 50% of the value thereof, and then defines continuously, in terms of the ordinary data base, the constant functional conditions, and responds to electric, thermal and mechanical discrepancies being involved with its corrective stabilization, recording, signaling and information by means of a display. The stabilization of the ordinary operation conditions, both of the motor and of the heating resistor is achieved by means of the corresponding sensor, the information from which is channeled towards and from the respective speed and temperature control while the signaling and the information are carried out by connecting the respective control in turn to the corresponding VU meter and the equipment display. The recording of events receives directly the information from sensors and from speed and temperature controls, while from the aforesaid speed and temperature controls the information is sent back to the parameter status verification point.

An apparatus for applying ionized particles is disclosed. The apparatus includes an ionized particle emitter for emitting ionized particles against an object; and an electric potential maintainer for maintaining electric potential of the object at a predetermined level such that the ionized particles emitted against the object by the ionized particle emitter are continuously attracted to the object while the electric potential is maintained. A method for applying ionized particles is also disclosed. The method includes emitting ionized particles against an object, and maintaining electric potential of the object at a predetermined level such that the ionized particles are continuously attracted to the object.

Hairdryer-ionizing device assembly including a box-like body for holding a suction part, a fan, a driving motor, a heater, an air flow outlet part, an electric switch assembly and an ion emitting device comprising a high voltage generator, from AC to DC, which is electrically coupled to an electrode, and being characterized in that the high voltage generator device is arranged at an intermediate region between the suction part and the air flow outlet part.
