Abstract
A dry-type cleaning chassis for cleaning a cleaning target by colliding the cleaning media with the cleaning target, the cleaning media being blown by an air flow includes an internal space where the cleaning media are to fly; an opening part being in contact with the cleaning target so that the cleaning media collide with the cleaning target; an air inlet duct introducing external air into the internal space; a suction port generating a first air flow caused by a circulating air flow in the internal space by suctioning the introduced external air; an injection port generating at least a second air flow increasing a speed of the cleaning media flown by the circulating air flow; and a porous unit passing objects removed from the cleaning target to a suction port side.
