AI Technical Summary

Benefits of technology

This vacuum cleaner has a unique design that allows the air stream to flow through the motor compartment and filter in a way that creates two perpendicular planes of exhaust. This design also includes a final filter that is positioned along a plane that is perpendicular to the first plane of exhaust. This results in a more efficient air stream flow and improved vacuum performance. The final filter is held by the canister assembly, which is pivotally connected to the nozzle assembly. The technical effects of this design include improved vacuum performance and more efficient air stream flow through the motor compartment and filter.

Problems solved by technology

The noise generated by the motor and the rapidly moving air is substantial in state-of-the-art vacuum cleaners.

Embodiment Construction

[0015]Reference is now made to FIGS. 1, 2 and 3 illustrating an upright vacuum cleaner 10. The vacuum cleaner 10 includes a body in the form of a nozzle assembly 12 and a canister assembly 14. The canister assembly 14 is pivotally connected to the nozzle assembly 12 in the manner of upright vacuum cleaners known in the art. Thus, the canister assembly 14 may be pivoted from the upright storage position illustrated in FIGS. 1 and 2 into an inclined position whereby an operator may freely move the vacuum cleaner 10 to and fro to clean an underlying floor or carpet.

[0016]The nozzle assembly includes an agitator cavity 16 that receives a rotary agitator 18. The rotary agitator 18 includes bristle tufts or other resilient projections 20. As the agitator 18 is rotated, the bristle tufts 20 beat dirt and debris from the nap of an underlying carpet or rug being cleaned.

[0017]The canister assembly 14 includes a primary housing 22, a bag compartment cover 24, a motor compartment cover 26 and ...

Abstract

A vacuum cleaner includes a body that carries a suction generator. A final filter is carried on the body downstream from the suction generator. The final filter is oriented along a first plane. Opposed side discharge outlets are carried on the body and oriented along a second plane substantially perpendicular to the first plane. Air is exhausted from the vacuum cleaner through succeeding compartments of increasing volume and rerouted or turned through different planes along a tortuous air path in order to muffle noise produced by the operating vacuum cleaner.

Description

TECHNICAL FIELD[0001]The present invention relates generally to the floor care appliance field and, more particularly, to a vacuum cleaner incorporating a noise suppression system.BACKGROUND OF THE INVENTION[0002]A vacuum cleaner is an electro-mechanical appliance utilized to effect the dry removal of dust, dirt and other small debris from carpets, rugs, fabrics or other surfaces in both domestic and industrial environments. The vacuum cleaner includes a suction generator generally comprising a fan and drive motor assembly. The suction generator draws an air stream entrained with dirt and debris into the nozzle of the vacuum cleaner. The particulate laden air is then drawn through a dirt collection vessel in the form of, for example, a filter or vacuum cleaner bag, a removable dirt cup or a cyclonic separation chamber and filter combination. The dirt collection vessel traps the dirt and debris from the air stream while substantially clean air is exhausted from the vacuum cleaner.[00...
