And it tries to make it possible to do it reliably.
- Patent Documents 1 and 2 the cleaning liquid storage part and the drying part of the object to be cleaned are separated from each other by a gate valve inserted from the side surface of the cleaning tank, thereby blocking the cleaning liquid storage part and the drying part of the object to be cleaned. And what is going to dry the to-be-cleaned thing in a drying part is known. Moreover, as shown in Patent Document 3, the cover for the cleaning liquid in the cleaning tank is pressed against the packing of the annular ridge disposed above the liquid level of the cleaning tank, thereby cleaning the cleaning liquid storage section and the object to be cleaned. It is known that an object to be washed is dried in the drying section while being disconnected from the drying section of the object.

This is made possible by reducing the pressure, and by using this depressurizable space, various cleaning operations other than drying under reduced pressure are made possible. In addition, a reliable airtight state is formed at the time of drying under reduced pressure so that no airtight leakage occurs.

If a pair of openings are provided on both sides of the working chamber, it is easy to put an object into and out of the working chamber and workability can be improved. Further, if only one opening is opened on one side of the working chamber, it is only necessary to form one cover, so that the structure of the apparatus can be simplified and an inexpensive apparatus can be obtained. By doing so, the effect of preventing airtight leakage can be improved.
