ABSTRACT:
A local cleaning system which uses a charged air shower unit for forming a shield curtain by means of an ion wind, and a local exhaust device for exhausting the air containing dirt and dust settled down on the floor by the ion wind to construct a clean shielded space with no need for a dedicated partition wall. With this local cleaning system, the charged air shower unit provides negative charges for gas molecules, and dirt and dust, floating microorganisms, odor constituents, and other foreign matters, for electrically neutralizing them, and leads the gas molecules and foreign matters which have lost the charges and which Brownian motion is suppressed, by means of the ion wind for effectively sucking them into the local exhaust device or air cleaner. Because a charged air curtain including an invisible ion wind provides a shield plane, a clean shielded space can be constructed with no need for a dedicated partition wall.
