Patent ID: 7854648

Claim:
A dry cleaning apparatus that uses a cleaning medium, said dry cleaning apparatus comprising: a circulating air current generating unit to generate a high-speed air current to cause a plurality of cleaning media to become airborne within a cleaning tank; a cleaning media accelerating unit to deliver a high-speed air current to cause the airborne cleaning media to collide with an object to be cleaned so as to remove an extraneous substance such as dust or particles attached to the object; a cleaning media regeneration unit to provide suction for removing any of the extraneous substance attached to the cleaning media; wherein each of the plurality of cleaning media includes an outer surface that comes into contact with an object to be cleaned; and an inner surface that remains out of contact with the object; wherein each of the plurality of cleaning media is flexible and formed in a shape that allows high-speed air current to flow from outside onto the inner surface of the cleaning medium, and wherein each of the plurality of cleaning media has a Young's modulus in a range between 0.2 GPa and 4 GPa.
