Abstract
Sootless ionizers are provided which greatly reduce the accumulation of ugly black soot on and about the ionizers and adjacent walls or ceiling in the room in which the air is being purified. To this end, the dependable improved ionizers are specially arranged to provide air channels which direct the flow of air past the needles or other ion emitters so that the ions are dispersed through the room for enhanced air purification and the ionized particles are prevented (blown away) from being collected in the ionizers. In one embodiment, the improved ionizers include a plug-in ionizer (PI-1) with an upwardly converging air channel, a curved deflector, and upper and lower sets of air channeling ribs to direct the flow of air past the ion emitters and way from the ionizers. In a second embodiment, the improved ionizer comprises a plug-in ionizer (PI-2) which is similar to the first plug-in ionizer (PI-1) except that it has a single elongated set of air channeling ribs and a motor driven fan to increase air flow. In a third embodiment, the improved ionizers comprise an industrial ionizer with air channeling ribs to direct the flow of air past the ion emitters and away from the ionizers. …
