A vacuum cleaner assembly comprising a main housing, a primary filter system, and a secondary filter system. The main housing includes an inlet and an outlet. The primary filter system filters the air prior to being exhausted outwardly through the outlet. The secondary filter system is placed in downstream airflow from the primary filter system and provides additional filtering of the air prior to being exhausted to atmosphere.

Vacuum cleaner

A vacuum cleaner assembly includes a main housing) having an inlet, a recess and an outlet disposed within the recess. A water bath filter is coupled to the main housing and disclosed between the inlet and the single outlet. The water bath filter is for filtering the air prior to exhausting the air outwardly through the outlet. A second filter is removably disposed adjacent said main housing single outlet within the main housing recess.

Filter for vacuum cleaner

A vacuum cleaner assembly (,) includes a main housing (,) having an inlet (,) and an outlet (,). A motor (,) is disposed within the main housing (,) for providing motive force to a cooling fan (,), a blower (,), and a separator (,). The separator (,) circulates the air and water bath (,) within a water bath pan (,) and provides, in combination with the water bath (,), a primary filter for filtering the air. A second filter assembly (,) is also provided preferably including a high efficiency filter (,or,), or HEPA rated filter, for filtering microscopic dust and dirt particles that escape the separator (,) and water bath (,) and is disposed after both the water bath (,) and the separator (,) for additional filtering of the air. Alternatively, it may be a non-HEPA rated filter (,). The second filter assembly (,) may also include a third filter element, which may be a carbon impregnated filter (,) for absorbing or trapping odors and is disposed in the air flow path after the second filter (,, or,). The second filter (,or,) and third filter (,) element are secured in a frame (,) as part of the second filter assembly (,). The second filter (,or,) and the carbon impregnated filter (,) within the frame (,) are disposed in a recess (,) which is integral with the main housing (,) allowing for direct and efficient flow of the air through the water bath (,), separator (,), and second filter assembly (,).

A vacuum cleaner assembly (10) is disclosed that includes a main housing (12) having an inlet (14) and an outlet (16). A motor (17a) is disposed within the main housing (12) between the inlet (14) and the outlet (16) for providing motive force to a cooling fan (17b), a blower (17c), and a separator (22). The cooling fan (17b) is mounted within the main housing (12) above the motor (17a) to circulate cooling air around the motor (17a). The blower (17c) is mounted within the main housing (12) below the motor (17a) for drawing air into the inlet (14) and exhausting air outwardly through the outlet (16). The separator (22) is mounted below the blower (17c) for circulating the air and water bath (20) within a water bath pan (36) and providing, in combination with the water bath (20), a primary filter for filtering the air prior to exhausting the air outwardly through the outlet (16). A second filter (24) is a high efficiency filter for filtering microscopic dust and dirt particles that escape the separator (22) and water bath (20) and is disposed after both the water bath (20) and the separator (22) and before the outlet (16) for additional filtering of the air prior to being exhausted. The second filter (24) is disposed in a recess (26) which is integral with the main housing (12) allowing for direct and efficient flow of the air through the water bath (20), separator (22) and second filter (24).

Water container for a vacuum cleaner

A motor housing for a vacuum cleaner includes a motor chamber supported within a main housing wall. A first airway defined between the motor chamber and the main housing wall provides a pathway for the working air flow within the vacuum cleaner. A second airway is defined through the motor chamber by an inlet opening and a venting outlet. The airway through the motor chamber allows air to flow along and directly encounter the motor during vacuum operation. The air flow through the first airway not only serves as the working air flow, but also as a secondary cooling air flow because the air passes along the exterior surface of the motor chamber and provides a cooling effect.

Vacuum cleaner motor housing

Dolly for a vacuum cleaner

A vacuum cleaner assembly having a separator of reduced dimensions. The separator is operated at preferably between about 20,000 rpm-30,000 rpm and includes a reduced number of slots formed therein. A labyrinth sealing plate and fan adapter are secured to an upper end of the separator to prevent water and dust and dirt particles from bypassing the separator during operation. The separator is preferably spaced from about 1.0 inch to about 6 inches above the upper surface of the liquid in a liquid reservoir of the vacuum cleaner assembly with which the separator is used. The separator, because of its reduced dimensions and weight, is able to be driven with a small conventional, and less costly and less powerful motor at a higher speed than previously designed separators without suffering breakage. The higher speed of 20,000-30,000 rpm helps to prevent the airflow through the separator from being impeded because of the reduced number of slots. The labyrinth sealing plate coupled to the separator helps to provide a labyrinth seal to prevent water and dust and dirt particles from bypassing the separator and entering the interior of a blower housing. In an alternative embodiment a spider member includes a circumferential raised shoulder portion which cooperates with a circumferential groove formed in a lower surface of the blower housing to form a labyrinth seal.
