Patent number: 7959717Abstract: 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.

Patent number: 7350317Abstract: 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.Type: GrantFiled: September 26, 2005Date of Patent: April 1, 2008Assignee: Matsushita Electric Works, Ltd.Inventors: Yasunori Matsui, Osamu Imahori, Shosuke Akisada, Fumio Mihara, Akihide Sugawa, Toshihisa Hirai, Takashi Nakagawa, Kozo Kawai, Naofumi Kodama, Tomohiro Yamaguchi, Kiyoshi Takashima, Kousuke Katayama, Junichi Watanabe
