US Patent:

55507034, Aug 27, 1996

Filed:

Jan 31, 1995

Appl. No.:

8/392379

Inventors:

Douglas H. Beyer - Cathedral City CA
Eugene V. Williams - Desert Hot Springs CA
Jose A. Alvarez - Palm Springs CA

Assignee:

Richmond Technology, Inc. - Redlands CA

International Classification:

H05F 306

US Classification:

361229

Abstract:

An air ionizing device that prevents contaminant buildup on the electrodes, comprising a housing that includes a low pressure plenum that meters dry gas to flow near an electrode, and the electrode is surrounded by an annular shaped shroud. The housing and shroud are configured to provide a laminar flow of dry gas around the electrode, such that moist room-air is prevented from reaching the electrode during ionization. The device may further include a plurality of electrodes and shrouds spaced laterally along an elongate housing, and a high pressure plenum to distribute gas at a plurality of locations to the low pressure plenum. A plurality of mounting bars connect each of the electrodes to wiring inside the low-pressure plenum, the wiring routed to a high voltage power supply. The outside of the housing is formed of smooth concave-shaped surfaces to avoid interfering with existing room-air flow. The air-ionizing device is low maintenance and inexpensive to manufacture.

International Classification:

H05F 306

US Classification:

361230

Abstract:

An air ionizing device that minimizes interference with existing room-air flow and lighting, comprising a narrow enclosed housing of an insulating material having intake openings and vent openings. Disposed inside the housing is a fan that takes room-air axially through the openings in the housing, and disperses the air radially. The room-air collects inside the housing until the capacity is reached, and then flows downwardly in a laminar fashion sufficiently near a plurality of electrodes to be ionized. The ionized air exits through vents in the housing and is directed towards the workbench. The housing may be extruded to many different lengths, and include a plurality of fans. Sections of the housing may be attached together to span across a long workstation. A conductive rail runs the length of the housing to electrically connect the electrodes. The outside of the housing is formed of smooth concave-shaped surfaces to avoid interfering with existing room-air flow.
