  • Patent number: 8418942
    Abstract: An oxidation and reduction fine particles generator includes an atomization electrode, a water feeder for supplying water to the atomization electrode and a high voltage generator, and also includes a switch device and a controller. The switch device changes an operation mode to an oxidation mode or a reduction mode. The controller generates negatively charged fine water particles including radicals through electrostatic atomization by applying a high voltage to water supplied to the atomization electrode in the oxidation mode. The controller also inactivates and activates the water feeder and the high voltage generator, respectively to generate reduction fine particles from the atomization electrode by dry discharge in the reduction mode.

  • Patent number: 8282027
    Abstract: An electrostatic atomizing device for ejecting a mist of charged minute particles includes metal ion elution means for eluting sterilizing metal ions into a liquid to be electrostatically atomized. The metal ions are taken up by the charged minute particles, and are ejected into an environment space together with the charged minute particles, thereby eliciting a sterilizing effect. The elution amount of the metal ions is regulated by varying the voltage applied between two kinds of metal bodies.

  • Patent number: 8235312
    Abstract: Disclosed is an electrostatic atomizer, which comprises a high-voltage applying section adapted to apply a high voltage between an atomizing electrode and a counter electrode so as to electrostatically atomize water supplied onto the atomizing electrode, wherein the high-voltage applying section is operable to set an absolute value of a voltage to be applied to the atomizing electrode smaller than an absolute value of a voltage to be applied to the counter electrode. This allows a physical object, such as an article stored in a mist-receiving space or an inner wall of a structural member defining the mist-receiving space to become less likely to be electrostatically charged, and makes it possible to avoid causing a problem about discomfort due to discharge of static charges when a user touches the physical object.

  • Publication number: 20120175439
    Abstract: An electrostatic atomization device having a simple structure and allowing for reduction in size. The electrostatic atomization device has an atomization electrode including a P type Peltier element and an N type Peltier element joined with the P type Peltier element. The atomization electrode is cuspate so as to form a projection with a joined portion of the P type Peltier element and the N type Peltier element. High voltage is applied to the P and N type Peltier elements so that discharging occurs at a distal portion of the atomization electrode, current flows to the P and N type Peltier elements to produce a cooling effect at the joined portion, and condensed water generated by the cooling effect is atomized by the discharging to generate charged fine water droplets.

  • Patent number: 8209990
    Abstract: An electrostatically atomizing unit for use in a temperature regulating appliance to add a function of generating a mist of charged minute water particles for deodorization and/or sterilization of a temperature-regulated space. The appliance has a cold space of which air is cooled by cooling means and is fed to cool the temperature-regulated space divided from the cold space by a partition. The atomizing unit has an emitter electrode which is configured to condense water from within a surrounding air. A high voltage source applies a high voltage to the emitter electrode to atomize the condensed water into the charged minute water particles which are discharged from the emitter electrode into the temperature-regulated space. The emitter electrode is provided with a cooling coupler which establishes a heat transfer relation through the partition to the cold space to cool the emitter electrode by making the use of the cooling means inherent to the appliance.

  • Publication number: 20120160940
    Abstract: An electrostatic atomization device that prevents the cooling capability from being lowered due to contact of an atomization electrode with another ember, while effectively preventing surplus production of condensed water that would destabilize discharging at the distal end of the atomization electrode. the electrostatic atomization device includes an atomization electrode having a cylindrical electrode body and a base which is informed at a basal end of the electrode body and has a larger diameter than the electrode from the base to produce condensed water on the atomization electrode. Voltage is applied to the atomization electrode when the condensed water is produced to generate charged fine water droplets. A partition plate includes an insertion hole that receives the electrode body of the atomization electrode. The partition plate and the base of the atomization electrode form a water collection region in between.
