摘要： A vacuum cleaner is provided that is alternatively operable as a stand alone, upright vacuum cleaner and as a canister vacuum cleaner. The vacuum cleaner includes a nozzle assembly having a beater brush, a suction fan and a motor that drives both the beater brush and suction fan. A dirt tube assembly includes a first air flow passageway that directs dirt from the nozzle assembly to a dirt box and also includes a second air flow passageway that directs dirt from the nozzle assembly to a handle. The handle includes an air flow passageway that is coupled to the second air flow passageway in the dirt tube assembly. The handle is alternatively interconnectable with a cap for sealing the handle air flow passageway to operate the vacuum cleaner as a stand alone, upright vacuum cleaner wherein dirt is directed from the nozzle by the nozzle suction fan through the first air flow passageway to the dirt box. The handle is also interconnectable with a hose assembly coupled to a canister unit having a suction fan driven by a motor such that dirt is directed by canister suction fan from the nozzle assembly through the second air flow passageway to the hose assembly and a canister dirt receptacle to operate the vacuum cleaner as a canister vacuum cleaner. The vacuum cleaner may also be operated in a clean out mode to automatically clean out the dirt box. Further, when operated as a canister vacuum cleaner, the nozzle suction fan and canister suction fan operate together to provide improved cleaning action.
摘要翻译： 提供一种真空吸尘器，其可替代地可操作为独立的，直立的真空吸尘器和作为吸尘器的吸尘器。 真空吸尘器包括具有打浆机刷，吸风机和驱动打浆机刷和吸风机的马达的喷嘴组件。 污物管组件包括第一气流通道，其将污垢从喷嘴组件引导到污物盒，并且还包括将污垢从喷嘴组件引导到手柄的第二气流通道。 手柄包括与污物管组件中的第二气流通道相连的气流通道。 手柄可互换地与盖相连，用于密封手柄空气流动通道以操作真空吸尘器作为独立的直立式真空吸尘器，其中污物通过喷嘴抽吸风扇从喷嘴引导通过第一空气流动通道到达污物箱 。 手柄还可与连接到罐单元的软管组件相连，该软管组件具有由电动机驱动的抽吸风扇，使得污垢由吸管风扇从喷嘴组件通过第二气流通道引导到软管组件， 操作真空吸尘器作为吸尘器。 真空吸尘器也可以在清洁模式下操作以自动清除污物盒。 此外，当作为罐式真空吸尘器操作时，喷嘴吸入风扇和罐吸入风扇一起工作以提供改进的清洁动作。

摘要： A dirt receptacle for a vacuum cleaner includes a rigid body for collecting dirt. The body includes an aperture formed in an upper surface thereof through which dirt may flow. One or more apertures are further formed in the sidewall of the rigid body with a filter disposed in each of the apertures through which air may be exhausted from the dirt receptacle. The rigid body further includes one or more air inlet valves that allow air to enter the dirt receptacle for automatic clean out thereof.
