Abstract
An air cleaner is described wherein an ion wind is generated by an ionizing element and directed to pass over a dust collector surface. By proper design and adjustment of the ionizing element and collector, the unit can be operated without emitting charged particles, if any, in other than the direction of orientation of the dust collector surface and thus avoiding smudging of the surrounding walls. The collector may be cylindrical in form and may be separately detachable, rendering it readily available for cleaning.
Claims18
An air cleaner for removing dust from the air comprising:
- a) at least one ion source;
- b) a cylindrical support located in opposition to and aligned with said ion source to serve as an airflow guide;
- c) a collector electrode having a conductive dust collecting surface formed on at least a portion of the inside of said cylindrical support;
- and
- d) a high voltage power supply of ionizing potential connected between said source and said dust collecting surface
- wherein said conductive dust collecting surface, acting as a counter-electrode, is positioned to induce the release of ions from said source and cause an ionic wind of air generated by said ion source to pass through said cylindrical support whereby said dust collecting surface may collect from the air dust that has been charged by ions emitted by said ion source.

An air cleaner for removing dust from the air comprising:
- a) at least one ion source;
- b) a support located in opposition to and aligned with said ion source;
- c) a collector electrode having a conducting dust collecting surface formed on a side of said support;
- d) a high voltage power supply of ionizing potential connected between said source and said dust collecting surface, and
- e) an insulative, charge-fixing electrode base for the ion source
- wherein said conducting dust collector surface, acting as a counter-electrode, induces the release of ions from said source and causes an ionic wind of air generated by said ion source to pass by said dust collector surface whereby said dust collecting surface may collect from the air dust that has been charged by ions emitted by said ion source, and wherein said ion source is carried by said electrode base which electrode base is positioned to become charged by the ions emitted by said ion source and to direct said ionic wind in the direction of said collecting surface.
