Definitions

  • the present invention relates to an ion generation apparatus, and more particularly to an ion generation apparatus for changing a high voltage applied to an electrode of an ion generator including a component for generating positive/negative ions.
  • a negative ion generator has been installed in electronic devices such as an air cleaner, such that the negative ions generated from the negative ion generator are provided to a room.
  • electronic devices such as an air cleaner
  • the negative ions generated from the negative ion generator are provided to a room.
  • an ion generation device for generating positive and negative ions to sterilize such bacteria has recently been developed such that the sterilizing power of the ion generation device can be improved.

  • the aforementioned ion generation device has been designed not to change the high voltage applied to the electrodes after deciding to apply a predetermined high voltage to the electrodes, such that it cannot change ion categories and a quantity of ions generated from the ion generation device. Therefore, although there is a need for the quantity of generated ions to be newly established due to installation environments of the ion generation device, the conventional ion generation device is unable to properly cope with the above problem, resulting in deterioration of use efficiency of the ion generation device.
  • an ion generation apparatus comprising: an ion generator including at least one of a positive ion generation electrode and a negative ion generation electrode, for receiving a high voltage to generate ions; a high voltage generator for applying a high voltage to the ion generator; and a controller for changing the high voltage applied to the ion generator.

  • the ion generation apparatus further comprises a high voltage generator which includes a square wave generator for generating a square wave signal, and the controller includes at least one of a frequency setup unit for establishing a frequency of the square wave signal and a duty-cycle setup unit for establishing an on-time duty cycle of the square wave signal.

  • An opening in which the positive ion generator 11 is installed is placed on the top of the support 100, such that the positive ion generator 11 is installed in the opening.
  • the positive ion generator 11 is adapted to generate positive ions.
  • a discharge electrode 13 is provided at the inner upper part of the positive ion generator 11, and an induction electrode 14 is provided at the center of the positive ion generator 11.
  • the remaining parts other than the discharge electrode 13 and the induction electrode 14 are formed of ceramic material, such that they form a protective layer.

These electrons are combined with oxygen molecules (O 2 ) contained in the air, such that a superoxide anion O 2 - is generated.
  • O 2 oxygen molecules

  • the negative(-) high voltage is applied to the negative ion generator 12
  • the positive ion generator 11 generates hydrogen ions, etc.
  • the negative ion generator 12 generates electrons and a superoxide anion O 2 - .
  • the hydrogen ions generated from the positive ion generator react with the electrons emitted from the negative ion generator, such that a hydrogen atom is formed.
  • a hydroperoxy radical (O-O-H) is formed.
  • the O 2 - electron is offset by static electricity of bacteria.
  • the O-O-H radical takes a hydrogen atom away from a protein indicative of a structural component of a cell membrane of the bacteria, such that it makes water. A protein molecule of the cell membrane from which the hydrogen atom is taken away is destroyed, and the cell membrane is also destroyed in such a way that sterilization is carried out.
  • the quantity of generated ions is regulated according to the variation in either the frequency or the on-time duty cycle of the positive(+) high voltage.
  • a high voltage generator 20 is connected between a DC (Direct Current) power-supply unit 21 for generating a predetermined DC power-supply voltage (e.g., DC 12V) and the ion generator 10, as shown in FIG. 4.

  • a negative(-) high voltage e.g., a voltage of several kV
  • a controller 24 is connected to the sine wave generator 22 such that the controller 24 establishes a frequency or on-time duty cycle of the sine wave signal.

  • the amplifier 33 amplifies a positive(+) DC power-supply voltage using a negative(-) high voltage (e.g., a voltage of several kV) opposite to the positive(+) DC power-supply voltage, such that it applies the amplified voltage to the negative ion generator 12.
  • a negative(-) high voltage e.g., a voltage of several kV
