    摘要: An electronic air cleaner is disclosed in which the corona discharge wire and the counterelectrode are positioned outside the flowpath of dust-laden air. Diverging electric force lines are discharged from the discharge wire electrode, which is nearer the flow path than the counterelectrode, when a high voltage is applied and ions are directed into the passing airflow path in a reacting area or zone. Dust contained in the air flow path is electrically charged by the ions and collected on a filter, which may also be electrically charged, positioned downstream from the reacting zone. In the device the discharge wire is not directly exposed to the dust-laden air, the electrically charged particles being collected on a separate, easily cleaned filter. The design of the electronic air cleaner requires less maintenance, easier cleaning and a longer period of operational quality.

    摘要: Electric blower assembly wherein air expelled by centrifugal force from impellers passes through volute chambers disposed peripherally with respect to said impellers and each defining a space which is increasingly larger as the distance from the impellers increases, whereby smooth air flow is produced in the volute chambers since the speed of air flow therethrough is lessened and pressure therein becomes static pressure. From the volute chambers air passes along inclined channels and then around a drive motor, whereby the drive motor is cooled. In entering at least part of each volute chamber air from the impellers comes into contact with a volute chamber wall extension which becomes gradually lower in a direction opposing that of impeller rotation whereby noise due to contact of a volute chamber wall by all portions of the air from the impeller does not occur simultaneously and a quieter blower assembly is provided.
