  • Patent number: 11881685
    Abstract: An ion generation device includes a discharge electrode substrate, an induction electrode substrate, and an insulating resin. The discharge electrode substrate on which a discharge electrode is mounted and a first electrode connected to the discharge electrode is formed. The induction electrode substrate on which an induction electrode configured to generate a discharge between the induction electrode and the discharge electrode and a second electrode connected to the induction electrode are formed. The insulating resin is filled at least between the discharge electrode and the induction electrode. The insulating resin provides insulation between the discharge electrode and the induction electrode. The first electrode and the second electrode are disposed and face each other at least partially. The first electrode, the second electrode, and the insulating resin interposed between the first electrode and the second electrode form a capacitor.

  • Patent number: 11576996
    Abstract: Provided is a discharge device that can improve the efficiency of generating reactive species. A discharging unit that discharges in response to an application of a voltage protrudes from a housing. The discharging unit is disposed in a duct through which gas flows. An upstream support is disposed upstream of the discharging unit in a direction of gas flow without overlapping the discharging unit. The upstream support protrudes further from the housing than the discharging unit. The upstream support includes a root portion joined to the housing. The root portion includes a widened portion that is disposed in the duct and that protrudes toward the discharging unit when viewed in the direction of gas flow.

  • Patent number: 10998159
    Abstract: An ion generator includes a high-voltage transformer having a secondary side that is not grounded; a discharge wire-pattern; an induction wire-pattern; a discharge electrode connected to a first terminal via the discharge wire-pattern, the first terminal being disposed on the secondary side of the high-voltage transformer; and an induction electrode connected to a second terminal via the induction wire-pattern, the second terminal being disposed on the secondary side of the high-voltage transformer. The first terminal has a first width. The discharge wire-pattern includes a discharge wide region having a second width greater than the first width. The discharge wide region and the induction wire-pattern at least partly overlap each other in plan view.

  • Patent number: 10980909
    Abstract: An ion generating device (1) includes discharge electrodes (21?22) each having a plurality of electrically conductive members (25?26) which form respective tip surfaces (36?37). A longer dimension direction of the tip surfaces (36?37) is nonparallel to an air sending direction (A). This allows for efficient release of ions.

  • Patent number: 10109449
    Abstract: Each of first to fourth needle-like electrodes is arranged such that a direction of extension thereof is parallel, and generates ions by discharge. Through a space, a gas for conveying the ions generated by the first to fourth needle-like electrodes flows. Needle tips of the first needle-like electrode and the second needle-like electrode protrude from a first wall surface that forms the space, are spaced apart from each other, and are arranged in line in the space. Needle tips of the third needle-like electrode and the fourth needle-like electrode protrude from a second wall surface that forms the space and faces the first wall surface, are spaced apart from each other, and are arranged in line in the space. The first needle-like electrode and the fourth needle-like electrode generate positive ions, and the second needle-like electrode and the third needle-like electrode generate negative ions.
