US Patent 7097695 Ion emitting air-conditioning devices with electrode cleaning features

An air conditioner device includes a housing, a first electrode disposed in the housing, and a second electrode removably disposed in the housing. The second electrode can be manually removed from the housing and then manually returned to a resting position within the housing. A base member is attached to a bottom portion of the second electrode. An at least partially flexible cleaning member is attached to the base member. The cleaning member frictionally cleans the first electrode when, after being removed from the housing, the second electrode is manually returned to the resting position within the housing.
