Abstract

A cyclonic separator assembly for use with a vacuum cleaner includes a body having an inlet, an outlet, and an inner surface. The cyclonic separator assembly also includes a cyclone unit positioned within the body between the inlet and the outlet. The cyclone unit has an outer perimeter that is spaced apart from the inner surface of the body to define an inlet space therebetween. The cyclone unit includes a plurality of first cyclones in communication with the inlet space and arranged along an outer circle adjacent the outer perimeter. The cyclone unit also includes a plurality of second cyclones in communication with the inlet space and arranged along an inner circle that is spaced apart from the outer circle such that each second cyclone is nested between two adjacent first cyclones. The plurality of first cyclones and the plurality of second cyclones are arranged in parallel.

Dependent claims

A cyclonic separator assembly for use with a vacuum cleaner, the cyclonic separator assembly comprising:

a body having an inlet, an outlet, and a central longitudinal axis;
and
a cyclone unit positioned within the body between the inlet and the outlet, the cyclone unit having an outer perimeter that defines a total cross-sectional area of the cyclone unit measured perpendicular to the central longitudinal axis, the cyclone unit including
a plurality of first cyclones arranged along an outer circle adjacent the outer perimeter, each first cyclone having an air outlet, a particle outlet, a first longitudinal axis extending between the air outlet and the particle outlet, and a first cross-sectional area measured perpendicular to the first longitudinal axis, and
a plurality of second cyclones arranged along an inner circle that is spaced apart from the outer circle, each second cyclone having an air outlet, a particle outlet, a second longitudinal axis extending between the air outlet and the particle outlet, and a second cross-sectional area measured perpendicular to the second longitudinal axis;
wherein the plurality of first cyclones and the plurality of second cyclones are arranged in parallel, and wherein a ratio of the sum of the first and second cross-sectional areas to the total cross-sectional area is between about 0.4 and about 0.6.
