ABSTRACT:
An organic solvent cleaning apparatus has a cleaning chamber that is hermetically sealed by operating a door provided at its entrance and that is rendered full of an organic solvent vapor to effect a cleaning operation, and that is formed with an entrance in a side portion of the cleaning chamber. The cleaning chamber is equipped with vapor supply means capable of supplying the vapor only during the cleaning operation and with vapor collecting means, including cooling coils that are lowered to condense the vapor, for collecting the vapor after the cleaning operation. In one embodiment, this organic solvent cleaning apparatus has a vertically movable cover which in its descended position surrounds a material to be cleaned and creates a seal with a reservoir of liquid solvent at its lower end to prevent supplied vapor from leaking out.
