  • Patent number: 6279590
    Abstract: A cleaning apparatus in accordance with the present invention includes a first inflow section, provided on a first side surface of a cleaning tank having a substantially rectangular parallelopiped shape, having two inflow openings, a second inflow section, provided on a second side surface facing the first side surface, having inflow openings, and outflow openings for releasing a cleaning liquid flown in from the first and second inflow sections. The cleaning liquid flowing in from the inflow openings forms complex and strong flows in the cleaning tank, thus removing contaminants on a cleaning target evenly and efficiently without nonuniformity and preventing stagnation of the cleaning liquid in the cleaning tank. The cleaning liquid released in filtered by a circulatory section and is allowed to flow into the cleaning tank again through a pipe.
