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 ion generation device applies a high voltage to an ion generator including a pair of positive and negative electrodes, such that it generates positive ions (e.g., hydrogen gas) and negative ions (e.g., 02-).
  • 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.

  • the high voltage generator includes a sine wave generator for generating a sine wave signal
  • the controller includes one of a frequency setup unit for establishing a frequency of the sine wave signal and a duty-cycle setup unit for establishing an on-time duty cycle of the sine wave signal.
  • the ion generation apparatus further comprises an entry unit for allowing a user to establish the frequency or on-time duty cycle of the sine wave signal having the high voltage, in which the controller changes the sine wave signal having the high voltage according to information established by the entry unit.
  • 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.
  • the ion generation apparatus further comprises an entry unit for allowing a user to establish the frequency or on-time duty cycle of the square wave signal having the high voltage, in which the controller changes the sine wave signal having the high voltage according to information established by the entry unit.

  • the ion generation device mounts an ion generator 10 for generating ions on a support 100.
  • the ion generator 10 includes a positive ion generator 11 for generating positive ions, and a negative ion generator 12 spaced apart from the positive ion generator 11 by a predetermined distance for generating negative ions.
  • 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.
  • the negative ion generator 12 If a negative(-) high voltage is applied to the negative ion generator 12, such as a negative ion generation electrode, the negative ion generator 12 emits electrons. 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 positive(+) high voltage i.e., a sine or square wave
  • the negative(-) high voltage is applied to the negative ion generator 12
  • the positive ion generator 11 generates hydrogen ions, etc.

  • 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 .
