Patent number: 7171722Abstract: A vacuum cleaning and/or drying systems having heaters which provide drying air to aid in drying or combined cleaning and drying. The system is particularly adapted and beneficial for use on carpets, but can also be used to clean other surfaces such as smooth floors or upholstery. The heaters are on a portable cleaning unit used within the room being cleaned. A support unit is preferably provided outside the room or building to generate vacuum and remove moisture from the room. The support unit is typically mounted on a vehicle and can provide compressed air or other gases and cleaning fluids. Compressed air can be used to agitate and facilitate both cleaning and drying. Compressed air can also be used to apply one or more additives, such as deodorizers and fragrances. The portable unit can also be used for drying flooded carpets and the like.Type: GrantFiled: January 10, 2003Date of Patent: February 6, 2007Inventor: Kris D. Keller

Patent number: 7168128Abstract: A wand for a domestic appliance (e.g., a vacuum cleaner) includes a plurality of tubes which are dimensioned to telescope inside one another. Each tube is associated with a securing mechanism for securing the tube in an extended position with respect to another of the tubes. Adjacent securing mechanisms are positioned on their respective tubes such that, when the tubes are retracted, one securing mechanism presses against another to release the other securing mechanism. Thus, a user does not need to separately operate each securing mechanism when extending the wand. Also, the tubes automatically secure themselves in an extended position with respect to one another. A hook on the widest tube cooperates with a collar on the narrowest tube to retain the tubes in a stored position.Type: GrantFiled: October 14, 2003Date of Patent: January 30, 2007Assignee: Dyson Technology LimitedInventor: Nicholas Alexander Evans

Patent number: 7162770Abstract: A vacuum cleaner having a nozzle, a handle pivotally attached to the nozzle, and a suction motor that has an inlet, and is adapted to generate a working air flow through the nozzle. The vacuum includes a separation system having an outer wall and a closed tube having at least a portion of its length located within the wall, and forming a separation chamber between the wall and the closed tube. The separation chamber has an inlet, in communication with the nozzle, that is adapted to impart a tangential component to the air flow as it flows through the separation chamber. A hollow tube is generally coaxially aligned with the closed tube and has a tube inlet at an end adjacent the closed tube and a tube outlet at an end opposite the closed tube. The tube outlet is in fluid communication with the suction motor inlet.Type: GrantFiled: November 26, 2004Date of Patent: January 16, 2007Assignee: Electrolux Home Care Products Ltd.Inventor: Don Davidshofer

Patent number: 7159272Abstract: The present invention provides a holder for storing accessories on a wet/dry vacuum. The holder securely attaches to the vacuum and readily detaches therefrom. The detachable holder may be detached with the accessories. While an operator dumps debris out of the drum of the vacuum, detaching the holder prevents the accessories from being inadvertently spilled out of or discarded from the holder. The detachable accessory holder fully secures to a bracket attached to the vacuum. The secure attachment prevents the holder from falling off or tipping on the vacuum. To attach the holder to the bracket and vacuum, grooves on the holder are set on to an axle of the vacuum. As the holder is pivoted about the axle, tabs and a latch on the holder engage slots and a step on the bracket. To remove the holder, the operator presses on the latch and lifts the holder from the bracket and the appliance.Type: GrantFiled: May 14, 2002Date of Patent: January 9, 2007Assignee: Emerson Electric Co.Inventors: Stuart V Holsten, Mark J Tomasiak

Patent number: 7150068Abstract: A vacuum cleaner power head (40) for vacuum cleaning and having two counter rotating agitators 52 and 54. Motor (60) rotates agitators (52) and (54) through transmission (70), and also rotates suction fan (65) to provide suction air to the rotary brush agitators. Exterior housing 48 and inner housing (49) provide air suction passageways to direct suction air through fan (65) and out of the housing to a dirt collection bag (34). Self-propelled function is provided by using user force on handle (32) to create differential contact friction between the two counter-rotating rotary brush agitators so that a net traction force is generated that propels power head (40) in the direction the user is pushing.Type: GrantFiled: August 12, 2003Date of Patent: December 19, 2006Inventor: Gary Dean Ragner
