Abstract

See full text

A dry cleaning casing of a dry cleaning apparatus includes a casing body including an internal space for flying a cleaning member, an opening to which a cleaning target is contacted to collide the cleaning member to the cleaning target, and an air introduction route to introduce external air to the internal space, by sucking air from the internal space while the opening is closed by the cleaning target, to generate rotating air flow for flying the cleaning member; a flow restriction member to define a rotation axis of the rotating air flow in the internal space; and a screen plate made of a porous plate to block movement of the cleaning member while passing through substance removed from the cleaning target.
