Patent attributes
An air purifier has a simply manufactured and assembled ionizer, which improves the charging efficiency for dust particles using multi-directional discharge and prevents electrical accidents. The air purifier includes an ionizer and a collector. The ionizer includes a first electrode and at least two second electrodes, the first electrode having at least two hollow, semi-cylindrically shaped electrodes, the at least two electrodes being connected successively and in parallel so that the first electrode has a corrugated shape, and the at least two second electrodes are positioned at inner spaces defined by the hollow semi-cylindrically shaped electrodes, respectively. The collector is electrically charged with a polarity opposite to a polarity of charged dust particles.
