Patent number: 9623447Abstract: The conventional washing apparatus has a double-cup washing tank that joins and separates to let work be placed therein, with nozzles set on the inner cup to allow a passage between it and the outer cup for spent liquid and/or air. The work is cleaned by washing detergent spirally flowing along the periphery of the inner cup by suction power within the passage, and then dried. Suction is not generated within the inner cup, so the spiral flow is too weak to make the tornado effect. This invention though resolves the above issues by an encased washing apparatus having a capsule-shaped washing chamber that joins and separates, has nozzles thereon, has a work table within that rotates by a drive device, has a drain at the bottom, and is characterized by washing detergent, cleaning water and/or air swirling by negative pressure within the washing chamber and then discharging into a drain.Type: GrantFiled: February 2, 2011Date of Patent: April 18, 2017Assignee: FINE MACHINE KATAOKA CO., LTD.Inventor: Keiji Kataoka

Publication number: 20110005555Abstract: A conventional invention has a structure of a washing chamber in which the work is set on a table and the entire surface of the work is consistently washed and dried by rotations in an orbital motion and a planetary motion of the washing and drying nozzles which are respectively provided in all four directions—top, bottom, right and left. The conventional invention effectively washes a greater area of the work or the like, but due to limitations of the structure, it can wash only small-sized works or small components. Also, it does not always sufficiently wash and dry large-sized works, and consequently overhaul such works. To resolve the problems, besides the above structures, the present invention provides an additional structure of a rotary frame to generate rotations in an orbital motion and planetary motion so that the works can be efficiently and entirely washed and dried, and the overhaul of the works can consequently be completed.Type: ApplicationFiled: January 5, 2010Publication date: January 13, 2011Inventor: Keiji Kataoka
