  • Publication number: 20240317582
    Abstract: An ozone generating body (3) includes a first electrode (10), a first dielectric (11) that covers the first electrode (10), a second electrode (30), and a second dielectric (31) that covers the second electrode (30). The second dielectric (31) forms a discharge space (DS) between the second dielectric (31) and the first dielectric (11). The ozone generating body (3) further includes a support portion (50) that supports the first dielectric (11) and the second dielectric (31). Young's modulus of the support portion (50) is less than those of the first dielectric (11) and the second dielectric (31).

  • Publication number: 20240286897
    Abstract: An ozone generator (100) includes a flow passage (1) having a cylindrical shape, an ozone generating unit (3) disposed in the flow passage (1), and a fan (2) disposed in the flow passage (1). When a specific frequency f is one of frequencies at which an air-column resonance occurs in the flow passage (1), ? is a wavelength of sound at the specific frequency f, and m is a natural number, at least a portion of the fan (2) is disposed within a range in which a distance from the inlet (5) in a height direction is (2m?1)?/8 or more and (2m+1)?/8 or less.

  • Publication number: 20240101420
    Abstract: An ozone generator (100) includes: a flow path (1) through which gas flows from an inlet (5) to an outlet (6); an ozone generation unit (3) disposed in the flow path (1); and an ozone sensor (4) disposed in the flow path (1) and upstream of the ozone generation unit (3). The flow path (1) has an upstream-side flow path (130) that forms a gas passing space (AR) located upstream of the ozone generation unit (3) and through which the gas flows from one side to another side in a predetermined direction. The inlet (5) is disposed closer to an outer circumferential portion (131) of the upstream-side flow path (130) than the ozone sensor (4).
