20090113663 | CYCLONIC SEPARATING APPARATUS - A cyclonic separating apparatus includes a cyclonic separator for separating dirt and dust from an airflow, an inlet to the cyclonic separator and a shroud comprising a wall having a multiplicity of through-holes forming an outlet from the cyclonic separator. The apparatus also includes a plurality of separate passageways provided immediately downstream of the through-holes. By providing this arrangement, the separate passageways can be located around other parts of the cyclonic separating apparatus inwardly of the shroud, allowing for better packaging of the components of the cyclonic separating apparatus. The shroud may be reduced in size because some of the space previously required for a single, large passageway can be used for other components of the cyclonic separating apparatus such a collector or a cyclone. The reduction in size of the shroud in turn allows for the cyclonic separating apparatus to be more compact. | 05-07-2009 |

20100319159 | TOOL FOR A SURFACE TREATING APPLIANCE - A tool for a surface treating appliance includes a main body connected to a conduit. The main body includes a first suction channel and a second suction channel in fluid communication with the first suction channel and located between the first suction channel and an outlet from the main body. In use, a relatively low vacuum is generated in the first suction channel which draws a first dirt-bearing fluid flow into the main body, and a relatively high vacuum is generated in the second suction channel, which draws a second dirt-bearing fluid flow into the main body and receives the first dirt-bearing fluid flow from the first suction channel. To maintain the pressure differences between the suction channels, the main body includes flexible surface engaging members located about the suction channels, and between the first suction channel and the second suction channel. | 12-23-2010 |
20120000029 | SURFACE TREATING APPLIANCE - A surface treating appliance includes a plurality of frusto-conical cyclones arranged in parallel. Each cyclone has a relatively wide, rigid frusto-conical portion and a relatively narrow, flexible frusto-conical portion connected to the relatively wide portion. The relatively wide portion includes at least one dirty air inlet, and the relatively narrow portion includes a dirt outlet. The relatively narrow portion vibrates during use of the appliance is dislodged dirt from the inner surface of the relatively narrow portion, the dislodged dirt being expelled from the dirt outlet. | 01-05-2012 |
20120272474 | SURFACE TREATING APPLIANCE - A surface treating appliance includes cyclonic separating apparatus having a plurality of cyclones arranged in parallel and a dust collector arranged to receive dust from each of the plurality of cyclones. Each cyclone has a fluid inlet and a fluid outlet. The plurality of cyclones is divided into at least a first set of cyclones and a second set of cyclones. The fluid inlets of the first set of cyclones are located in a first plane and the fluid inlets of the second set of cyclones are located in a second plane spaced from the first plane. This enables the separating apparatus to have a compact appearance. | 11-01-2012 |
