    摘要: An upright vacuum cleaner includes an upright housing section and a nozzle base section. A cyclonic airflow dirt and dust separating chamber is defined in the upright housing section. A suction source pulls air and entrained dirt, dust, and other contaminants through a main suction opening formed in the underside of the nozzle base section and into the cyclonic airflow chamber. The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container that defines the chamber. A main filter element filters residual contaminants from the suction airstream between the chamber and the suction source. An exhaust filter housing includes an airstream suction duct in fluid communication with an outlet of the airflow chamber and an inlet of the suction source. An outlet of the suction source is in fluid communication with an exhaust plenum of the exhaust filter housing. An exhaust filter is positioned radially outward of the exhaust plenum such that exhaust air is forced radially outward through the exhaust filter from the exhaust plenum to ensure that the air discharged into the atmosphere is contaminant free, including those contaminants introduced into the airstream by the suction source itself.

    摘要: A vacuum cleaning including a nozzle base comprising a primary and secondary suction opening, a suction source positioned within a first cavity in the nozzle base, and a dust cup releasably positioned within a second cavity in the base. The dust cup comprises a first inlet in communication with the primary suction opening, a second inlet in communication with the secondary suction opening, and an outlet. An above floor cleaning tool is in communication with the second inlet. A first filter assembly is positioned adjacent the outlet of the dust cup. A second filter is positioned between the suction source and the first filter. An exhaust opening and filter are positioned downstream of the suction source to prevent particles from venting to atmosphere. The vacuum cleaner further includes a handle assembly comprising an elongated connecting portion and a handle. The handle is removable for use as a handle for an above-floor cleaning tool. The elongated connecting portion is removable for use as a wand for an above-floor cleaning tool. A hose is removably attached to the nozzle base and to the handle.

    摘要: A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber. A main filter assembly, preferably including filter medium comprising polytetrafluoroethylene (PTFE), is located in the cyclonic chamber so that a suction airstream moving from the main suction opening to the inlet of said suction source by way of the cyclonic airflow chamber passes through the filter medium thereof after said airstream moves in a cyclonic fashion within the cyclonic airflow chamber to remove residual particulates from the suction airstream before it leaves the cyclonic chamber. A HEPA filter can be provided to filter the suction airstream exhausted through the outlet of the suction source prior to the airstream being discharged from the vacuum.

    摘要: An upright vacuum cleaner (A) includes an upright housing section (B) and a nozzle section (C). A cyclonic airflow dirt and dust separating chamber (54) is defined in said upright housing section. A suction source (E) pulls air and entrained dirt, dust, and other contaminants through a main suction opening (26) formed in the underside (24) of the nozzle and into the cyclonic airflow chamber (54). The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container (52) that defines the lower portion of the chamber (54). A main filter assembly (50) includes a main filter element (H) for filtering residual contaminants from the suction airstream between the chamber and the suction source. The main filter element is preferably made from high-density polyethylene porous filter media. A final filter assembly (F) filters the suction airstream discharged by the suction source to ensure that the air discharged into the atmosphere is contaminant free, including those contaminants introduced into the airstream by the suction source itself.

    摘要: A method for manufacturing a bucket of a wet/dry vacuum cleaner includes the step of producing a one piece conical shell with an open top end and an open bottom end. The shell is tapered such that its bottom end has a larger diameter than its top end. A base plate is also produced. Subsequently, the base plate is secured to the shell to close the shell bottom end and form a bucket. An aperture may extend through the shell and a hose inlet can be snapped to the shell through the aperture therein. A latch handle can be snapped to a latch mounting wall of the shell and a handle can be secured to the shell as well. The shell can also include an integral skirt in which are formed caster housings as well as a tool storage cavity.
