Patent number: 8458852Abstract: The present invention relates to a system of creating and applying a heated cleaning fluid to a surface. The system includes a housing with a first, a second and a third exhaust gas opening. A first, second, and third heat exchanger are enclosed within the housing. The first and second exchangers are serially arranged, while the third is at an angle relative to the first and second and directly adjacent to the first opening. Super heated exhaust gas flows through first opening and third exchanger. Heated gas flows through the second opening and passes below the third exchanger. Super heated exhaust gas exiting the third exchanger mixes with the heated gas in a mixing chamber of the housing, which is then supplied to the first and second exchangers. Fluid passes through the three exchangers and exits the third exchanger heated. That heated fluid passes to a cleaning wand for application.Type: GrantFiled: May 20, 2010Date of Patent: June 11, 2013Assignee: Kärcher North America, Inc.Inventor: Ron Williams

Publication number: 20120115401Abstract: A floor care apparatus is provided that utilizes at least one cylindrical pad to remove a floor finish. More specifically, a cylindrical pad having an abrasive surface is integrated onto a cylindrical scrubber brush or associated core or roller commonly used in the art. The main outwardly-facing surface of the pad contacts the floor to remove a predetermined amount of floor finish wherein generated debris is expelled away from the pad. After finish removal, a new layer of finish is applied to the floor. Thus, the need to remove all finish layers from a flooring surface is alleviated, which saves time and money.Type: ApplicationFiled: October 13, 2011Publication date: May 10, 2012Applicant: KARCHER NORTH AMERICA, INC.Inventors: James D.

Publication number: 20110315787Abstract: A pressure washer device is provided that employs an unloader bypass valve that directs a selective amount of fluid via a small diameter bypass line back to a water storage tank. The small amount of fluid allows for the pump to remain working and introduces cooler water into a bypass circuit, thereby allowing the thermal relief valve to be omitted. The diameter of the bypass line is of such a diameter to prevent siphonage of the detergent associated with the pressure washer system into the water storage tank as well.Type: ApplicationFiled: June 23, 2010Publication date: December 29, 2011Applicant: Karcher North America, Inc.Inventors: Paul W. Linton, Derek Knight
