Patent number: 8429792Abstract: A cleaning appliance includes a motor arranged to drive a fan for generating suction air flow and a cleaner head having a drivable agitator with a dedicated motor. The agitator drive motor has a selectively-operable switch and a resettable circuit breaker arranged such that, when the switch is activated, the circuit breaker is reset. A button actuates the switch and simultaneously resets the circuit breaker. When there is a blockage so that the circuit breaker trips out the motor, the user can reset the circuit breaker and restart the agitator motor by the simple act of depressing one button, thereby obviating the need for a separate control.Type: GrantFiled: July 17, 2007Date of Patent: April 30, 2013Assignee: Dyson Technology LimitedInventors: Stuart Lloyd Genn, James Dyson, Thomas Jenkins

Patent number: 7721385Abstract: A filter housing includes an inlet for receiving an airflow, a cavity for receiving a filter and an airflow passage between the inlet and the cavity. At least one vane, positioned in the airflow passage, partitions the airflow passage into a plurality of ducts. The vanes lie adjacent to, or contact, the upstream surface of the filter such that each duct communicates with a separate portion of the upstream surface of the filter. The airflow passage extends in a direction which is inclined to the upstream surface of the filter. The vanes help to distribute the flow of air more evenly across the surface of the filter and also help to reduce acoustic emissions from the machine of which the filter housing forms a part.Type: GrantFiled: February 3, 2003Date of Patent: May 25, 2010Assignee: Dyson Technology LimitedInventors: Stuart Lloyd Genn, Richard Anthony Mason

Publication number: 20100071153Abstract: A domestic appliance, such as a cyclonic vacuum cleaner, includes a component such as a separating apparatus, carried by a chassis. A catch is operable to release the component from the chassis. The component and the chassis can move with respect to each other. When the appliance is lifted there is relative movement, against the force of a resilient member, between the component and the chassis, so that the catch occupies a position that inhibits its release. Previous catches that inhibited from release when the appliance is lifted had a drawback in that slight relative movement between the component and the chassis when the appliance was resting on a surface tended to put the catch into the unreleasable position. The resilient member provides resistance to the catch moving into the locked position, thereby ensuring that the catch is inhibited from release only when the appliance is lifted from a surface.Type: ApplicationFiled: July 16, 2007Publication date: March 25, 2010Inventor: Stuart Lloyd Genn

Publication number: 20100037425Abstract: An attachment for a cleaning appliance includes a main body having a head and a passageway through which a fluid is able to flow. The head includes first and second suction openings, each of the first and second suction openings being arranged to engage with a surface to be cleaned. The first and second suction openings are in simultaneous communication with the passageway. By providing such an arrangement, both of the first and second suction openings are independently able to engage with a surface to be cleaned and a rotatable connection between the head and a neck is not required.Type: ApplicationFiled: July 16, 2007Publication date: February 18, 2010Applicant: DYSON TECHNOLOGY LIMITEDInventor: Stuart Lloyd Genn

Patent number: 7425225Abstract: An exhaust assembly for an appliance includes a filter housing for retaining a filter and an exhaust duct which receives airflow from the filter housing. One or more vanes are positioned in the filter housing for guiding airflow from the exhaust side of the filter to the exhaust duct. The vanes spread the airflow entering the exhaust duct across the width thereof so as to reduce noise and to reduce the velocity of the exiting air. The exhaust duct increases in cross-sectional area in the direction of flow through the exhaust duct so as to further reduce the velocity of the exiting air.Type: GrantFiled: February 3, 2003Date of Patent: September 16, 2008Assignee: Dyson Technology LimitedInventors: Stuart Lloyd Genn, Richard Anthony Mason
