Patent ID: 7940509

Claim:
An ionizer having a discharge-electrode cleaning mechanism, the ionizer comprising: a case; an air hole formed in the case; a fan that supplies air, the fan being provided inside the air hole; a plurality of discharge electrodes that generates positive ions and negative ions by corona discharge, the plurality of discharge electrodes being provided at positions exposed to and/or facing the air hole in the case; an electrode support frame that is detachably attached to the case with the plurality of discharge electrodes being mounted on the electrode support frame; and a cleaner for cleaning the plurality of discharge electrodes, the cleaner moveably attached to the electrode support frame in such a manner that the cleaner can move from one discharge electrode to another as well as between one discharge electrode and another while being brought into contact with the plurality of discharge electrodes one after another, wherein the cleaner occupies a retraction position that is distanced from the area of the air hole when the electrode support frame is attached to the case; and the cleaner becomes moveable for the purpose of cleaning the plurality of discharge electrodes when the electrode support frame is detached from the case.
