  • Patent number: 7494532
    Abstract: A carrier is used to carry a liquid, and a high voltage is applied between a discharge end of the carrier and an opposed electrode to emit ionized liquid particles. The carrier has a liquid collecting end opposite to the discharge end to feed the steam of the liquid from a steam generator, condensing the liquid therearound, and feeding the condensed liquid to the discharge end. Accordingly, even when the liquid contains cations such as those of Ca and Mg, the steam of the liquid can extremely reduce the content of these impurities, avoiding the precipitation of the impurities at the discharge end of the carrier to assure stable electrostatic atomization.
    Type: Grant

  • Patent number: 7473298
    Abstract: Charged fine particulate water is provided, which has a nanometer particle size, for example, a particle size of 3 to 100 nm, and contains radicals such as hydroxyl radicals and superoxides. This charged fine particulate water can be generated by applying an electric-field intensity of 700 to 1200 V/mm between a pair of electrodes, while supplying water between the electrodes. By allowing the thus obtained charged fine particulate water to diffuse into an indoor space, it is possible to effectively remove bad odor components/bacteria from the indoor space.
