  • HAND HELD APPLIANCE
    Publication number: 20170265615
    Abstract: A hand held appliance, such as a hairdryer, includes a body, a fluid flow path extending through the body in an axial direction from a first fluid inlet through which a first fluid flow enters the appliance to a first fluid outlet for emitting the first fluid flow from the appliance, a primary fluid flow path extending from a second fluid inlet through which a primary fluid flow enters the appliance to a second fluid outlet, a section of the primary fluid flow path extending through the body in the axial direction and surrounding the fluid flow path, and a heater located within the section of the primary fluid flow path for heating fluid passing through the primary fluid flow path, and wherein the heater has a length extending in the axial direction.

  • Fan assembly
    Patent number: 9745981
    Abstract: A nozzle for a fan assembly has an air inlet, an annular air outlet, and an interior passage for conveying air from the air inlet to the air outlet. The interior passage is located between an annular inner wall, and an outer wall extending about the inner wall. The inner wall at least partially defines a bore through which air from outside the nozzle is drawn by air emitted from the air outlet. The inner wall is eccentric with respect to the outer wall so that the cross-sectional area of the interior passage varies about the bore. The variation in the cross-sectional area of the interior passage can control the direction in which air is emitted from around the air outlet to reduce turbulence in the air flow generated by the fan assembly.

  • Hand dryer
    Patent number: 9743813
    Abstract: A wall-mountable hand dryer for drying one side of a user's hands at a time, the dryer having two nozzle sections—one for each hand—which nozzle sections are positioned towards the front of the dryer so that they are spaced away from the wall in use, the nozzle sections each extending to span the width of a user's open hand and being arranged for directing drying air down onto the front or back of said hand as it is inserted lengthwise underneath the nozzle sections from the front of the dryer, wherein the dryer comprises a downwardly pitched guide part positioned behind each nozzle section for guiding the pitch of the user's hands underneath the nozzle sections.

  • Hand dryer
    Patent number: 9743814
    Abstract: A hand dryer having a left-hand nozzle section which, in normal use, is used to dry a user's left hand and a right-hand nozzle section which, in normal use, is used separately to dry the user's right hand, the left-hand nozzle section being arranged to emit drying air along a first direction—outwardly to the left of the dryer—and the right-hand nozzle section being arranged to emit drying air in a second direction—outwardly to the right of the dryer—said first and second directions having a downward and/or forward component.

  • Vacuum cleaner tool
    Patent number: 9700188
    Abstract: A tool for a vacuum cleaner that comprises a nozzle and a bristle assembly. A suction opening is provided in the base of the nozzle, which extends from a front to a rear of the nozzle. The bristle assembly is mounted within the nozzle and protrudes through the suction opening. The suction opening is delimited along its length by a leading edge and a trailing edge, and at least part of the leading edge is raised relative to a front end and a rear end of the nozzle. Consequently, when the tool is swept over a cleaning surface and the front end and the rear end of the nozzle contact the cleaning surface, a gap is created between the cleaning surface and the leading edge.

  • Hand held appliance
    Patent number: 9681726
    Abstract: Disclosed is 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.

  • FAN WITH A FILTER
    Publication number: 20170138374
    Abstract: A fan assembly for creating an air current is described, the fan assembly having a nozzle, a system for creating an air flow through the nozzle and a filter for removing particulates from the air flow, the nozzle having an interior passage, a mouth for receiving the air flow from the interior passage, and a Coanda surface located adjacent the mouth and over which the mouth is arranged to direct the air flow, wherein the fan provides an arrangement producing an air current and a flow of cooling air created without requiring a bladed fan, i.e. air flow is created by a bladeless fan.

  • Cleaning appliance
    Patent number: 9609990
    Abstract: A cleaning appliance of the cylinder type comprises a separating apparatus for separating dirt from a dirt-bearing fluid flow, and a floor-engaging rolling assembly. The separating apparatus comprises a first cyclonic separation unit having a low efficiency cyclone and a second cyclonic separation unit having a plurality of second cyclones. The rolling assembly comprises a main body and a pair of floor-engaging wheels. The main body comprises a recess in which the separating apparatus is received such that when the cleaning appliance is viewed from either side at least one fifth of the width of the low efficiency cyclone is hidden from view by a portion of the rolling assembly at the point of maximum depth of the recess.
