  • Patent number: 7567420
    Abstract: An electrostatically atomizing device includes an emitter electrode, an opposed electrode opposed to the emitter electrode, and a cooling means which condenses the water on the emitter electrode from within the surrounding air, and a high voltage source applying a high voltage across the emitter electrode and the opposed electrode to electrostatically charge the water for atomizing charged minute water particles from a discharge end of the emitter electrode. The device further includes a controller for discharging the charged minute water particles in a stable manner. The controller monitors a discharge current flowing between the two electrodes to control the cooling means for keeping the discharge current at a predetermined level, thereby regulating the atomizing amount of the charged minute particles from the emitter electrode.

  • Publication number: 20090179093
    Abstract: An electrostatically atomizing device includes an emitter electrode, an opposed electrode disposed in an opposed relation to the emitter electrode, liquid supply means for supplying a liquid to the emitter electrode, and high voltage generating means for applying a high voltage across the emitter electrode and the opposed electrode. The liquid supplied onto the emitter electrode is electrostatically charged through application of the high voltage, as a result of which charged minute liquid particles are discharged from a discharge end of the emitter electrode. The device includes detecting means for detecting a discharge condition developed between the emitter electrode and the opposed electrode, and a controller for controlling the high voltage generating means to regulate its voltage output so as to maintain a predetermined discharge condition, based on detection results by the detecting means.

  • Publication number: 20090134249
    Abstract: An electrostatic atomizer includes an atomizing electrode, a water supply unit for supplying water to the atomizing electrode, a high voltage power circuit and a control unit. The high voltage power circuit applies a high voltage to the atomizing electrode to electrostatically atomizing water supplied to the atomizing electrode and to generate electrically charged water particles. The control unit controls the high voltage power circuit such that the voltage applied to the atomizing electrode is gradually increased at the time of starting the electrostatic atomizer. Further, the control unit may control the high voltage power circuit such that the voltage is increased to a target voltage in steps at the time of starting the electrostatic atomizer, and an increment of the voltage at each step is decreased as the voltage approaches the target voltage.

  • Publication number: 20090114747
    Abstract: The liquid supplied to an emitter electrode located at a tip of an atomization nozzle receives the high-voltage and electrically charged. The mist of the charged minute water particles of nanometer sizes is generated from the emitter electrode. A pressure regulating means regulates a pressure applied to the liquid on the tip of the emitter electrode. Therefore, the mode of generating the mist of the charged minute water particles of nanometer sizes or the mode of generating the mist of the charged minute water particles of nanometer and micron size is selected.

  • 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: 5459389
    Abstract: A dual-charging system for a portable electric appliance such as a video camera comprises a rechargeable battery pack having a built-in charge circuit and a separate charger unit. The battery pack is capable of selectively taking a first charging operation with the use of the built-in charge circuit and a second charging operation with the use of a charge circuit of the charger unit. The charge circuit of the charger unit is designed such that a charging rate of the battery pack by the second charging operation is faster than that by the first charging operation. Therefore, when a rapid charging of the battery pack is desired, it is preferred to select the second charging operation. On the other hand, when the electric appliance is used, for example, during a journey, it is preferred to select the first charging operation because the charger unit is inconvenient to carry during a journey.
