  • Patent number: 9351386
    Abstract: A polarity control unit includes a flag storage unit that stores any one of a first polarity pattern by which a positive direct-current voltage is applied to discharge needles in a first group and a negative direct-current voltage is applied to discharge needles in a second group and a second polarity pattern by which a negative direct-current voltage is applied to the discharge needles in the first group and a positive direct-current voltage is applied to the discharge needles in the second group, a flag update unit that rewrites one flag stored in the flag storage unit to another flag when a power switch is turned on from its off state or is turned off from its on state, and a command unit that commands a polarity pattern corresponding to the flag stored in the flag storage unit to be output from the polarity output unit.

  • Patent number: 9338867
    Abstract: An ionizer includes a polarity output unit that can selectively output, to a discharge unit, one of a first polarity pattern where the polarity output unit applies a positive direct-current voltage to a first group of discharge needles and applies a negative direct-current voltage to a second group of discharge needles and a second polarity pattern where the polarity output unit applies a negative direct-current voltage to the first group of discharge needles and applies a positive direct-current voltage to the second group of discharge needles and a polarity control unit configured to control the first and second polarity patterns. The polarity control unit includes a current detection unit configured to detect respective direct currents passing through the first group of discharge needles and the second group of discharge needles.

  • Patent number: 8116060
    Abstract: An ionizer includes a fan for blowing air, the fan being provided in an air blowing port which opens in a case, and a plurality of discharge electrodes for generating positive and negative ions by corona discharge, the discharge electrodes being provided in the case at positions facing the air blowing port. The ionizer also includes a plurality of discharge electrode pairs each constituted by two discharge electrodes for generating ions of different polarities. When a tip-center distance denotes a distance from the electrode tip to the center of the air blowing port, the tip-center distances of the two discharge electrodes in the discharge electrode pairs are different from each other.

  • Patent number: 7940509
    Abstract: Discharge electrodes for generating ion and a member for cleaning the discharge electrodes are mounted on an electrode support frame, which is detachably attached to the case of an ionizer. When the electrode support frame is attached to the case, the cleaning member occupies a retraction position where the cleaning member does not shut off or disturb air that is supplied from a fan. Upon the detachment of the electrode support frame from the case, the cleaning member becomes moveable. Then, the cleaning member is moved while being brought into contact with the discharging parts of the discharge electrodes one after another. As a result, the cleaning member sweeps dust or other particles off the discharging parts thereof.

  • Patent number: 7898790
    Abstract: An ionizer is formed by coupling a fan unit provided with a discharge electrode and a fan and a control unit provided with an indicator and an adjuster to each other, and both units are changeable between a normal coupling condition, where both are directed in the same direction, and an opposite coupling condition, where they are directed in opposite directions to each other, and in addition, a power/signal arrangement of the connection terminals of the separate connector is bilaterally symmetrical such that same power and signals ale transmitted and received between the separate connectors of both units connected to each other in either coupling condition of aforementioned both units.
