Description

  The present invention relates to an ion generator, and more particularly, to an ion generator for efficiently diffusing positive ions and negative ions into a space in a windless environment.

  As an ion generation method for generating positive ions, negative ions, or both positive ions and negative ions at a discharge electrode, methods such as corona discharge, dielectric barrier discharge radiation, and water fragmentation are known. In the ion generation method using corona discharge, positive ions and negative ions are generated by applying a high voltage to a discharge electrode that generates ions. When a positive voltage is applied to the discharge electrode, positive ions are generated, and when a negative voltage is applied, negative ions are generated.

When positive ions H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and negative ions O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) are simultaneously generated and sent into the air, Positive ions and negative ions are said to be effective in removing airborne bacteria and mold bacteria in the air attached to bacteria and viruses floating in the air, or in suppressing viruses. This removal effect and suppression effect are considered to be more easily obtained when positive ions and negative ions are uniformly present in the entire space.

  In general, in order to send ions into the air, there are many devices having a structure in which ions are blown off into the air by wind force generated by an installed blower. The energy required to generate ions is much greater than the energy required to send ions into the air. Considering power consumption, it is difficult to realize an ion generator using a battery as a power source.

The first discharge electrode 221a included in the first main electrode 221 and the second discharge electrode 222a included in the second main electrode 222 are arranged so that the needle-shaped tip portion faces each target direction.

  On the other hand, the third discharge electrode 231a included in the sub-electrode 231 is disposed in the downward direction of the ion generator 2 so that the needle-shaped tip portion thereof faces. By arranging in this way, positive ions and negative ions are released not only in the target direction but also in other directions, and are diffused more throughout the space.

The ion generation control unit 21 includes a main electrode control unit 211 and a sub electrode control unit 212.

  Connection and operation of the diode 23, the resistor 24, the two-terminal thyristor 26, the step-up transformer 27, the capacitor 25, the diode 28, and the diode 29 included in the main electrode control unit 211 are the same as those in FIG.

  The anode terminal of the diode 28 is connected to the first discharge electrode 221 a included in the first main electrode 221. As a result, the negative voltage of the step-up AC voltage output from the secondary side of the step-up transformer 27 is applied to the first discharge electrode 221a.

  The cathode terminal of the diode 29 is connected to the second discharge electrode 222 a included in the second main electrode 222.

With this configuration, it is possible to change the ion generation specifications of the first main electrode 221 and the second main electrode 222 and the sub electrode 231.

  Furthermore, the controllability of the ion generator 2 is increased by using power supplies having different frequencies and phases instead of supplying the commercial AC power of 100 V to the ion generator 2. The ion generation control unit 21 shown in FIG. 4 can increase the amount of ions generated by increasing the frequency of the power supply to be supplied. Further, when the power supply voltage is increased, the amount of ions generated also increases. It is also possible to reduce the amount of ion generation by reducing the frequency and voltage of the power source.

  The ion generator 2 alternately discharges negative ions from the first main electrode 221 and positive ions from the second main electrode 222.
