  • Patent number: 10039428
    Abstract: An upright vacuum cleaner comprising a vac-motor for drawing dirty air in through a floor-engaging cleaner head on the vacuum cleaner, a separating apparatus for separating dirt from the dirty air, an elongate air duct for carrying air to or from the separating apparatus, and a suction wand which is stored on the vacuum cleaner and which can be connected to the separating apparatus via a hose as required to clean above the floor. The external surface of the air duct defines an elongate recess for receiving the stored suction wand such that the air duct partly surrounds the stored wand. This provides a compact configuration.

  • Patent number: 10016040
    Abstract: A hand held appliance, such as a hairdryer, includes a body, a duct, a fluid flow path extending through the duct from a first fluid inlet of the appliance to a first fluid outlet of the appliance. A primary fluid flow path extends from a second fluid inlet through which a primary fluid flow enters the appliance to a second fluid outlet. A fan unit is located in the primary fluid flow path for drawing fluid through the second fluid inlet. A filter is located in the primary fluid flow path. Fluid is drawn through the fluid flow path by fluid emitted from the second fluid outlet. A heater is provided in the body and extends at least partially along and around the duct.

  • Patent number: 9974421
    Abstract: A cleaning appliance includes separating apparatus for separating dirt from a dirt-bearing fluid flow, a floor engaging rolling assembly housing a motor driven fan unit for drawing the fluid flow through the separating apparatus, a chassis connected to the rolling assembly, and a duct for conveying the fluid flow to the separating apparatus. To improve the stability of the appliance, the duct has an inlet section which is connected to the chassis for pivoting movement relative to the chassis as the appliance is maneuvered over a floor surface. An outlet section for coupling the inlet section to the separating apparatus is releasably connected to the rolling assembly to facilitate the removal of any blockages within the duct.

  • Publication number: 20170280948
    Abstract: The invention relates to a wall-mountable hand dryer of the type which uses an air-knife to wipe the water from a user's hand. In accordance with the invention, the hand dryer is configured to have a maximum depth, front-to-back, of less than 150 mm when it is surface-mounted on—not recessed within—the wall. The air-knife is discharged downwardly through one or more discharge apertures on the dryer. These discharge apertures are configured so that the air-knife is discharged in front of the wall or a rear part of the dryer, and is discharged forwards towards the user at a downward angle. The downward angle of the air-knife is such that the air-knife projects to a distance of at least 75 mm in front of the wall or, as the case may be, in front of the rear part of the dryer.

  • Publication number: 20170280848
    Abstract: A hair care appliance comprising a body, a fluid flow path extending through the body from a fluid inlet to a fluid outlet and a PCB extending about the fluid flow path. The PCB may be annular. The PCB may be isolated from the fluid flow path. The PCB may comprise a first layer and a second layer. The first layer may extend substantially continuously about the fluid flow path and the second layer may extend partially about the fluid flow path. The second layer may be adjacent the first layer and may be downstream of the first layer. The body may comprise a duct and the fluid flow path extends through the duct. The PCB may extend about the duct. The body may comprise a primary fluid flow path extending about the duct which may be in fluid communication with the PCB.
