  • Publication number: 20100133366
    Abstract: An air conditioning system with an electrostatically atomizing function includes an electrostatically atomizing unit and a ventilation duct which flows conditioned air. The electrostatically atomizing unit generates a mist of charged minute water particles. The electrostatically atomizing unit is provided with a discharge port which locates adjacent to an air outlet of the ventilation duct. The mist of the charged minute water particles flows into an airflow which is sent from the ventilation duct. The mist of the charged minute water particles effectively spreads to the space by the air flow without dissipating inside the ventilation duct.

  • Publication number: 20080292450
    Abstract: Blower apparatus has: an air duct having suction and supply openings; a blower fan for creating a flow of air in the duct; and an electrostatic atomizer. The atomizer includes a hollow body exposed to the air in the duct. The body is provided therein with an electrostatic atomization chamber, and has a barrier, an inlet and an outlet. The barrier is put in the duct so that a part of the air flowing in the duct collides with the front of the barrier and thereby pressure-increased air is obtained. The inlet is located at the front side of the barrier so that the pressure-increased air can enter the chamber through the inlet. The outlet is located at the rear side of the barrier so that all the pressure-increased air higher than that of the air flowing in the duct, from the chamber can flow out into the duct.

  • Patent number: 7350317
    Abstract: In an electrostatic atomizing hairdryer, electrostatically atomized mist generated in an electrostatic atomizing unit is effectively scattered into airflow emitted from a main body of the hairdryer so that the mist can be sprayed to hair uniformly and a time necessary for treatment of hair can be shortened. A tank constituting the electrostatic atomizing unit is detachably provided on a portion in the vicinity of an outer periphery of the main body, and an electrode unit for generating the mist is provided in a path of airflow sucked in an inside of the main body so as to be insulated from heat of a heating unit by an adiabator. A mist emitting opening from which the mist is emitted is disposed on a plane substantially the same as and at substantially the center of an air exit opening of the main body. Thereby, the mist emitted from the mist emitting opening is effectively scattered into the airflow emitted from the air exit opening.
