Claim:
1. A dry-type cleaning chassis for cleaning a cleaning target by colliding cleaning media with the cleaning target, the cleaning media being blown by an air flow, the dry-type cleaning chassis comprising: an internal space to allow the cleaning media to circulate aerially within the internal space; an opening part to be in contact with the cleaning target so that the cleaning media collide with the cleaning target; an air inlet duct to introduce external air into the internal space; a suction port to generate a first air flow by suctioning the introduced external air through the air inlet duct, to cause a circulating air flow in the internal space; an injection port disposed parallel to the air inlet duct to generate a second air flow in a same direction as that of the first air flow, to increase a speed of the cleaning media flown by the circulating air flow; and a porous unit to pass objects removed from the cleaning target to a suction port side.
