PROBLEM TO BE SOLVED: To provide a dry cleaning machine which can purify a solvent by effectively removing stains while preventing the stains in a solvent tank from accumulating with a simple structure and by involving no significant cost increases. SOLUTION: The end 23a of a first return conduit 23 to put the solvent returning through a filter in the solvent tank 7 is bent into an L-shape, and attached to the vicinity of an inside bottom wall 7c in the position near to an inside wall 7a. The end of a suction conduit 8 to suck up the solvent is introduced to the vicinity of the inside bottom wall 7c in the position separated from the inside wall 7a and the center. The four corners of the solvent tank 7 are arc inside walls 7b. The delivery pressure of the solvent delivered from the end 23a of the first return conduit 23 by a pumping action during solvent purification forms an eddy current in the solvent tank 7 and stains are wound up and diffused. After the stains are sucked up from the suction conduit 8 and removed by the filter, the solvent is returned to the solvent tank 7. COPYRIGHT: (C)2008,JPO&INPIT
