  • Patent number: 8951024
    Abstract: An air blower includes a motor; a fan connected to an output shaft of the motor and rotatively driven by the motor; and a fan nut fixing the fan onto the output shaft of the motor, a diffusive substance is kept in the fan nut provided on the output shaft of the motor, and an ion generating unit is attached to a motor body concentrically with the output shaft. Therefore, the diffusive substance, positive ions and negative ions may be diffused without interrupting blowing and without harmfully affecting the air blowing function. Since the diffusive substance and the ion generating unit are provided inside a fan guard, an infant or the like may be prevented from touching them, and thus, the safety may be secured.

  • Patent number: 8797704
    Abstract: A space-saving mounting structure of an air blower having a vibration-insulating function is achieved to reduce a size of an ion generating apparatus. A holding case that holds an air blower and a mount having an air blowing duct are provided in a body case. A cushioning member is provided on an outer surface of a fan casing of the air blower. The air blower is held between the holding case mounted to the body case and the mount as a part of the body case. Two mounting members are formed on the fan casing. One mounting member is held between a pair of regulating members and formed on the holding case. The other mounting member is held between regulating members and formed on the holding case and the mount, respectively.

  • Patent number: 8607472
    Abstract: A hand dryer is equipped with a hand insertion area (10), having a width that is able to accommodate hands, a high-pressure air generator (2), which generates a high-pressure airflow, discharge nozzles (N1, N2), which are disposed in the upper surface of the hand insertion area (10) and blow the high-pressure airflow, an exhaust duct (4), which is connected between the exhaust side of the high-pressure air generator (2) and the discharge nozzles (N1, N2), an ejection port (23), which opens to the space surrounding the hand dryer, a switching damper (24), which opens a portion of the exhaust duct (4) and is connected to the ejection port (23), and an ion generator (22), which generates ions having sterilization action into the high-pressure airflow passing through the exhaust duct (4) on the upstream side of the switching damper (24).
