Patent number: 7552507Abstract: A cleaning head for a vacuum cleaner comprises a housing for facing a surface being cleaned, a first suction opening, a brush bar operable on the surface being cleaned through the first suction opening, a second suction opening and means for switching suction air flow between the first and second suction openings as required. The second suction opening may be narrower than the first opening, to provide a higher speed of suction airflow and hence improved dust collection when the brush bar is not being operated.Type: GrantFiled: September 7, 2007Date of Patent: June 30, 2009Assignee: VAX LimitedInventor: Gavin Burnham

Publication number: 20090158551Abstract: Combined nozzle for a dust vacuum-cleaner includes a brush with an interchangeable arrangement at the end of a tube connected to a suction device. The brush has a lower planar face and joint for an arrangement in two different transverse positions with respect to the tube or two different positions longitudinally in the tube extension. In each position, the suction is achieved by an opening in the planar face, or an opening at one of the ends. The joint includes a pivot about at least two axes, such that, when in a position for suction by an end, the brush is oriented so that the lower face and the longitudinal axis of the brush are essentially parallel to the axis of the suction tube.Type: ApplicationFiled: July 27, 2006Publication date: June 25, 2009Inventors: Frederic Varichon, Denis Varichon, Vincent Varichon, Alice Varichon, Doris Varichon, Francoise Thibault

Patent number: 7441307Abstract: A restricting device is positioned in the flow duct leading from the main inlet to the cleaning head of a vacuum cleaner and is movable between a restrictive position, in which it serves to restrict the cross-section of the discharge outlet, and an open position, in which it restricts the cross-section of the discharge outlet to a lesser extent. The restricting device is movable by the passage of debris along the flow duct.Type: GrantFiled: September 10, 2003Date of Patent: October 28, 2008Assignee: Dyson Technology LimitedInventor: David Benjamin Smith

Patent number: 7441305Abstract: The invention is directed to a floor cleaner apparatus, such as a vacuum cleaner, including a housing have a particle retaining element and a head operably connected to the housing. The head features an intake port through which dirt and other particles enter the head and a motor and fan assembly that creates suction during operation. A passageway or duct extends between the intake port through the motor and fan assembly. Within the duct, an internal divider forms a plurality of discrete intake chambers wherein each chamber is in fluid communication with the intake port. A beater element, such as a rotatable cylinder with a brush, is positioned above the intake port and proximate the intake chambers. A chamber control mechanism is provided to sequentially apply suction through the various intake chambers to both focus and increase the suction applied to the floor and thereby increase the amount of dirt and particles removed by the cleaner.Type: GrantFiled: August 4, 2006Date of Patent: October 28, 2008Inventor: Gregory R. Cascio

Patent number: 7392566Abstract: A cleaning machine for cleaning a surface is provided. The cleaning machine includes a base assembly that moves along the surface and a liquid distribution system associated with the base assembly for distributing the cleaning solution to the cleaning surface. A suction nozzle assembly is mounted to the base assembly and includes a front nozzle portion and a rear nozzle portion. The front nozzle portion defines a fluid flow path having an inlet opening and an outlet opening and the rear nozzle portion defines a fluid flow path having an inlet opening and an outlet opening. A suction source is in fluid communication with the suction nozzle for applying suction to draw the cleaning solution and dirt from the surface and through the suction nozzle assembly. The fluid flow path of the front nozzle portion is closed in response to the base assembly moving in one of the forward direction and rear direction.Type: GrantFiled: October 30, 2003Date of Patent: July 1, 2008Inventors: Evan A. Gordon, Sergey V. Makarov, Aaron P. Tondra, Michael A. Durbin, Robert Bauman

Patent number: 7377009Abstract: A complex type cleaner includes: a cleaner body having at least one of a dust collecting container for storing dust or foreign materials and a water collecting container for storing contaminated water; and a suction head having a dust suction opening disposed at a lower portion of the cleaner body and sucking dust when the cleaner performs a vacuum cleaning and a suction head having a suction nozzle for sucking contaminated water when the cleaner performs a water cleaning. By implementing both vacuum cleaning function for sucking dust and water cleaning function in one cleaner, a cost can be reduced, users' convenience can be improved, and the cleaner can be conveniently kept in storage.Type: GrantFiled: June 30, 2004Date of Patent: May 27, 2008Assignee: LG Electronics Inc.Inventors: Yong Woo Lee, Choon Myun Chung, Ho Seon Rew, Hyeun Sik Nam

Patent number: 7266862Abstract: A suction apparatus of a cleaner includes: a suction motor inserted in a cleaner body and generating a suction force; a filter for collecting dust or filth sucked by a suction force generated for the suction motor; a suction head connected to the filter by a suction pipe and sucking dust and filth on the floor by the suction force generated from the suction motor; and an auxiliary suction unit installed at the opposite side of a side where the suction pipe of the suction head is connected. A cleaning performance is enhanced by compensating a suction force at a portion where the suction force is relatively weak.Type: GrantFiled: November 6, 2003Date of Patent: September 11, 2007Assignee: LG Electronics Inc.Inventors: Hyeun Sik Nam, Yong Woo Lee, Ho Seon Rew, Choon Myun Chung
