    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.

    Abstract: A cleaner head for a cleaning appliance includes a housing having an upper surface and an underneath surface in which at least on suction opening is formed. The underneath surface has opposing side edges each having a first part which lies adjacent the suction opening or openings and forms a sharply-defined edge with the upper surface and an upwardly curved second part which is located rearwardly of the suction opening or openings. This arrangement is advantageously used in vacuum cleaners or other cleaning appliances in which a ball-type support allows an increased level of steerability involving lateral movement of the cleaner head across the surface to be cleaned. The upwardly curved side edges of the underneath surface of the cleaner head reduce the amount of effort required to achieve the steering by presenting a smoothly curved surface to the carpet or other floor covering.

    Abstract translation: 用于清洁器具的清洁器头包括具有至少在吸入口形成的上表面和下表面的壳体。 下表面具有相对的侧边缘，每个边缘具有邻近吸入开口或开口的第一部分，并且形成具有上表面的明确限定的边缘和位于吸入口或开口的后方的向上弯曲的第二部分。 这种布置有利地用于真空吸尘器或其他清洁设备中，其中球型支撑件允许增加水平的可操纵性，其涉及清洁器头横过待清洁表面的横向移动。 清洁器头部的下表面的向上弯曲的侧边缘通过向地毯或其它地板覆盖物呈现平滑的弯曲表面来减少实现转向所需的力量。

    Abstract: A fan assembly for generating an air flow within a room includes an air inlet section having an air inlet, an impeller, and a motor for rotating the impeller about an impeller axis to draw an air flow through the air inlet, and an annular nozzle having an inner wall, an outer wall extending about the inner wall, an air inlet for receiving the air flow, an air outlet for emitting the air flow, and an interior passage located between the inner wall and the outer wall for conveying the air flow to the air outlet, the inner wall defining a bore through which air from outside the nozzle is drawn by the air flow emitted from the air outlet. A support assembly supports the air inlet section and the nozzle on a ceiling of the room.

    Abstract: A surface treating appliance includes a first cyclonic separating unit including at least one first cyclone, a second cyclonic separating unit located downstream from the first cyclonic separating unit and including at least one second cyclone, and a third cyclonic separating unit located downstream from the second cyclonic separating unit and including a plurality of third cyclones arranged in parallel about an axis. Each third cyclone has a fluid inlet and a fluid outlet. The plurality of third cyclones are divided into at least a first set of third cyclones and a second set of third cyclones, with the fluid inlets of the first set of third cyclones being arranged in a first group and the fluid inlets of the second set of third cyclones being arranged in a second group spaced along said axis from the first group.

    Abstract: An upright surface treating appliance includes a main body having a user operable handle, a surface treating head connected to a yoke moveable relative to the main body, a stand moveable relative to both the main body and the yoke between a supporting position for supporting the main body in an upright position, and a retracted position, and a stand retaining mechanism for releasably retaining the stand in the supporting position and from which the stand is releasable upon application of a force to one of the main body and the stand. The yoke is moveable relative to the main body in response to an impact on the surface treating head to apply said force to the stand. This allows the force of the impact on the surface treating head to be transferred through the stand to the stand retaining mechanism, which, depending on the magnitude of the impact, can release both the stand and the yoke for movement relative to the main body. This avoids the need to provide separate releasing mechanisms for both the yoke and the stand.
