ION GENERATION ELEMENT AND STERILIZATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an ion generation element capable of sterilizing the air while suppressing the generation of ions. SOLUTION: This ion generation element 1 has a discharge electrode 11 disposed on a surface of a dielectric 10; and an opposed electrode 12 disposed in parallel with the discharge electrode 11 by imposing the dielectric 10 therebetween, and a semiconductor optical catalyst 13 is disposed along a boundary portion between the discharge electrode 11 and the surface of the dielectric 10. Surface creeping discharge is generated by applying an AC voltage to the discharge electrode 11 and the opposed electrode 12, then, plus ions H+(H2O)n and minus ions O2-(H2O)n can be generated in a large quantity. The generation of ions harmful to a human body can be suppressed simultaneously. COPYRIGHT: (C)2005,JPO&NCIPI
