摘要： A vacuum cleaner dirt containment system with a bag chamber having an open end, an outlet adapted to be in fluid communication with a vacuum fan inlet located on the vacuum cleaner housing, and a plurality of locator ribs extending from an inner wall of the bag chamber. Each locator rib has a landing adjacent an inner wall of the bag chamber, and a pin located inward of the landing and extending from the landing towards the open end of the bag chamber. A filter bag assembly is adapted to be inserted into the bag chamber, and has a flange attached to an open end of a permeable filter bag. A flange air inlet passes through the flange into the bag. The flange has openings located to be inserted over the locator rib pins, and support segments located to abut the locator rib landings. The lid is selectively attachable to the open end of the bag chamber, and includes an air inlet mounting tube that extends into the flange air inlet when the lid is attached to the open end of the bag chamber. A bag having locating features and variations of the foregoing are also provided.

摘要： A vacuum cleaner having a base with a: nozzle opening, rear housing attached to the base, dirt separator with inlet and outlet passages, vacuum fan, accessory hose, and valve system to connect the separator alternately to the nozzle opening and hose. The valve system has a valve body having a first inlet connected to the nozzle opening and a second inlet connected to the hose, a hose connector that pivots with respect to the valve body, a connector passage through the hose connector, and a flexible outlet hose having a first end connected to the connector passage and a second end connected to the separator inlet passage. The valve inlets are generally equidistant from the connector pivot and the hose connector is pivotable to rotate the first hose end relative to the second hose end to selectively place the connector passage in communication with the first and second valve inlets.

摘要： A vacuum cleaner is disclosed having a motor inlet conduit and sound deadening material disposed within the motor inlet conduit for reducing the overall noise level of the vacuum cleaner. The motor inlet conduit fluidly connects a dirt receptacle chamber and a motor inlet, and may have a generally continuous cross-sectional profile and one or more expanded regions for housing the sound deadening material. With the sound deadening material installed in the one or more expanded regions, the motor inlet conduit may form a smoothly changing profile along its entire length and reduce the overall noise level of the vacuum cleaner.
摘要翻译：公开了一种真空吸尘器，其具有设置在电动机入口管道内的电动机入口导管和消音材料，用于降低真空吸尘器的整体噪声水平。电动机入口导管将污物容器室和电动机入口流体连接，并且可以具有大致连续的横截面轮廓和用于容纳防声材料的一个或多个扩展区域。通过将防声材料安装在一个或多个扩展区域中，电动机入口导管可沿其整个长度形成平滑变化的轮廓，并降低真空吸尘器的整体噪声水平。
