摘要： 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.

摘要翻译： 一种具有减小尺寸的分离器的真空吸尘器组件。 分离器优选在约20,000rpm-30,000rpm之间操作，并且包括在其中形成的减少数量的槽。 迷宫式密封板和风扇适配器固定在分离器的上端，以防止水和灰尘和灰尘颗粒在操作过程中绕过隔板。 优选地，分离器在使用分离器的真空吸尘器组件的液体容器中离液体上表面约1.0英寸至约6英寸的间隔。 分离器由于其尺寸和重量的减小，能够以比以前设计的分离器更高的速度用小的常规且成本较低且功率较低的马达驱动，而不会发生断裂。 20,000-30,000rpm的较高速度有助于防止由于槽数减少而导致通过分离器的气流受到阻碍。 联接到分离器的迷宫式密封板有助于提供迷宫式密封，以防止水和灰尘和灰尘颗粒绕过分离器并进入鼓风机壳体的内部。 在替代实施例中，一个蜘蛛构件包括周向凸起的肩部，其与形成在鼓风机壳体的下表面中的周向凹槽协作以形成迷宫式密封。
