Abstract:
1. An ionizer comprising: a hollow casing containing a high voltage power unit and a control unit inside; and a plurality of electrode units each including needle electrodes for generating corona discharge, and an air outlet for blowing an air stream around the needle electrodes, the plurality of electrode units being arranged in a line along the longitudinal direction of the casing, wherein the hollow casing comprises a lower casing portion and an upper casing portion, the lower casing portion holding the high voltage power unit, the control unit, and the electrode unit, and the upper casing portion mounted on an upper portion of the lower casing portion and covering the high voltage power unit and the control unit, and at least one of the upper casing portion and the lower casing portion is formed of synthetic resin, and in the inside of the upper casing portion or the lower casing portion made of the synthetic resin, a conduit continually extending from one end to the other end in the longitudinal direction of the hollow casing is integrally formed with the upper casing portion or the lower casing portion, and a part of a conduit wall of the conduit serves as a part of the inner wall of the upper casing portion or the lower casing portion, and an air flow path in the inside of the conduit communicates with the air outlet of respective electrode units.
