<P>PROBLEM TO BE SOLVED: To provide a dry cleaning housing configured such that the size of an opening can be set to cope with a non-planar cleaning surface shaped like a convex surface to prevent the leakage of a cleaning medium in cleaning, and that the rate of a gas flow at the opening side in release or non-cleaning can be secured to prevent the leakage of the cleaning medium for contributing to the expansion of a cleaning field. <P>SOLUTION: An opening 18 is formed in the bottom surface of a housing body 42 connected to suction means (not shown), and a ventilation member 55A with a porous structure is formed so as to be adjacent to the opening 18. The opening area of the opening 18 is set to be small so that the opening 18 can be butted to a cleaning object 20 whose cross section is shaped like a circular-arc without generating any gap as shown by Fig.5(b). An air flow quickly flows from an inlet 50, and a swirl airflow 30 is generated. In release, outside air flows from the opening 18 and the ventilation member 55 as shown by Fig.5(a) so that the leakage of a cleaning medium 5 from the opening 18 can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
