METHOD FOR VAPOR-CLEANING OBJECT TO BE CLEANED AND DEVICE THEREFOR

摘要

[Problem] An outflow port for allowing a cleaning vapor to flow out into a normal-pressure workroom is provided to a covering plate, and thus the cleaning vapor flows out into the workroom from the outflow port and the cleaning vapor does not flow out to the full inner diameter of the workroom; therefore, very little of the air in the workroom is lifted upward and discharged to outside the workroom. If an object to be cleaned is subject to vapor-cleaning, a tubular cleaning tube is disposed on the outer periphery of the outflow port on an upper surface of the covering plate, making it possible to collect the cleaning vapor and possible to cause there to be very little pushing out of the air from the workroom. [Solution] An outflow port (10) is provided to a covering plate (2) so as to cause a cleaning vapor (5) to flow into an upper normal-pressure workroom (8). The outflowed vapor can be condensed at a position lower than the normal-pressure workroom (8) using a condensation section (11), and a tubular cleaning tube (12) is disposed on the outer periphery of the outflow port (10) on an upper surface of the covering plate (2); consequently, it is possible to draw the cleaning vapor into the cleaning tube (12) and vapor-clean an object to be cleaned (7) held within the cleaning tube (12).
