  • Patent number: 10207019
    Abstract: Provided is a compact ion generator. A control substrate (30) and an ion generating section (41) are provided concentrically around a motor (31) without overlapping each other, which motor (31) is configured to cause a fan (33) to rotate. The fan (33) is configured to send, more outwards than a radial direction, air sucked in from a side of a first direction which is along a rotational axis direction. A fan cover (50) has (i) a first air flow path (52) configured to guide, in the radial direction, the air sent by the fan (33) and (ii) a second air flow path (53) configured to cause the air, which has been guided by the first air flow path (52) to flow in the radial direction, to be sent towards the side of the first direction. The ion generating section (41) constitutes a part of a wall of the first air flow path (52).

  • Patent number: 9276385
    Abstract: Two flow passages are provided for allowing the passage of air sent out from a blower in the same direction individually and discharging the air to outside. An ion generation unit for generating positive ions by only corona discharge is arranged at one flow passage, and an ion generation unit for generating electrostatic atomized water particles with negative polarity by electrostatic atomizing phenomenon is arranged at the other flow passage. A throttle is provided at the one flow passage for making the wind speed of air flowing through the one flow passage faster than the wind speed of air flowing through the other flow passage. Since positive ions having shorter lifetime are emitted more than electrostatic atomized water particles with negative polarity having longer lifetime, the balance between positive and negative polarities in the air can be sustained over a long period of time.

  • Patent number: 8432660
    Abstract: In an ion generating unit configured to control driving of a plurality of ion generating elements for generating ions by a controller, the controller drives the ion generating elements upon start up, and is configured to keep driving for a predetermined time period; thereby, the ion concentration of a space upon start up is quickly raised to a predetermined concentration. Further, the controller is configured to drive the ion generating elements intermittently and one after another in order after the predetermined time period has elapsed; the product life is elongated while maintaining the predetermined ion concentration and shortening the driving time of the ion generating elements.
