Ionizer having cleaning system
View Patent ↗An object of the present invention is to provide an ionizer having a cleaning system for cleaning an electrode needle of the ionizer automatically or remotely, while also being compact in size. The cleaning system ( 6 ) has a rotating member ( 61 ) configured to coaxially rotate with the fan ( 3 ), a plurality of rods ( 62 a to 62 d ) attached to the rotating member ( 61 ) such that each rod extends radially from the rotating member, and brushes ( 63 a to 63 d ) each attached to the end of each rod. The rotating member ( 61 ) is driven by an electromagnetic solenoid ( 64 ) via a coupling means ( 66 ).
1. An ionizer comprising:
at least one electrode needle for generating air ions by corona discharging;
an air conveying means for generating an air flow by which the air ions are conveyed; and
a cleaning system for cleaning the electrode needle,
wherein the cleaning system comprises:
a cleaning member configured to come into contact with the electrode needle; and
an actuator configured to move the cleaning member to the electrode needle back and forth from opposing clockwise and counterclockwise directions.
2. The ionizer as set forth in claim 1 , wherein the actuator is positioned on the lateral side of the air conveying means in relation to the direction of the air flow by the air conveying means.
3. The ionizer as set forth in claim 1 , wherein the cleaning member is a brush.
4. The ionizer as set forth in claim 1 , wherein the actuator is a bi-directional solenoid.
5. An ionizer comprising:
at least two electrode needles for generating air ions by corona discharging;
an air conveying means for generating an air flow by which the air ions are conveyed; and
a cleaning system for cleaning the electrode needles,
wherein the cleaning system comprises a first brush configured to come into contact with one electrode needle and a second brush configured to come into contact with another electrode needle,
and wherein the first and second brush are configured to come into contact with their corresponding electrode needle at different times from each other, and wherein the first and second brush are configured to come into contact with their corresponding electrode needle back and forth from opposing clockwise and counterclockwise directions.
6. The ionizer as set forth in claim 5 , wherein the different brushes respectively contact one electrode needle and opposing another electrode needle at the same time.
7. The ionizer as set forth in claim 5 , wherein the cleaning system comprises a rotating member rotatable about one axis and a plurality of rods radially attached to the rotating member, each having the first or the second brush, the plurality of rods being attached to the rotating member at different angle intervals.
