A vacuum cleaner assembly is disclosed. The vacuum cleaner assembly includes a housing assembly having a motor connected to a vacuum source, a particulate collection pan interconnected to the housing and a base and an illumination source for illuminating the particulate collection pan.

Water basin illumination

A vacuum cleaner apparatus includes a housing, a motor disposed within the housing and having an output shaft, and a fan coupled to the output shaft for generating a vacuum airflow through an air intake port in the housing. A separator is operably coupled to the output shaft for separating dust and dirt particulates entrained in air ingested through the intake port. The separator has a body that defines a longitudinal axis of rotation and the motor drives the separator to rotate about the axis. The body includes a plurality of longitudinally extending vanes with each vane presenting a curved flow surface for increased particulate separation as the body rotates about the axis. The longitudinally extending vanes include beveled lower ends that reduce foaming. The separator also includes a plurality of secondary particle impacting vanes positioned in the bottom of the separator for trapping particulates within said separator.

Separator with multiple function vanes for a vacuum cleaner apparatus

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.

Reduced diameter separator for a vacuum cleaner apparatus

A safety interlock circuit for a vacuum cleaner system is disclosed for interrupting the flow of current through conductors of a vacuum hose and handle assembly whenever an electrical attachment accessory is disconnected from the handle assembly during operation of the vacuum. A pulse-type reset circuit is also disclosed for re-enabling current flow through the conductors of the vacuum hose and handle assembly after the electrical attachment accessory has been reattached to the handle assembly. The safety interlock circuit of the preferred embodiment comprises a relay coil, a plurality of normally open relay contacts, and a current sensing resistor, all connected in series with an AC power source and a motor of the electrical attachment accessory. A voltage doubler is also connected in parallel with the current sensing resistor for supplying a DC voltage to the relay coil. The safety interlock circuit operates to interrupt current flow by opening the normally open relay contacts whenever the relay coil is de-energized. The pulse-type reset circuit comprises a momentary contact pushbutton reset switch, a plurality of transistors, a capacitor, and a plurality of optical-electrical coupling devices. The pulse-type reset circuit operates to supply a pulse of current to the relay coil to temporarily energize the relay coil to thereby close the normally open relay contacts, thereby allowing current flow through the current sensing resistor and allowing the voltage doubler to apply a voltage across the relay coil to sustain operation of the motor.
