Ion generating element and ion generator, air conditioning apparatus, cleaner and refrigerator containing the same

Abstract

An inner electrode formed inside a dielectric body and a surface electrode formed on a surface of the dielectric body. The surface electrode is formed in a grid pattern with pointed parts formed inside the grid section. Each pointed part is in the shape of a triangle whose vertices are two arbitrary points on a side of the grid section and an arbitrary point inside the grid section, or a quadrangle whose vertices are a crossing of grid lines, an arbitrary point near a straight line connecting crossings of grid lines in the diagonal positions, and two arbitrary points on sides of the grid section. An ion generating element is formed which can generate positive ions and negative ions. The ion generator can be used in an air conditioning apparatus, cleaner or refrigerator.
