Benefits of technology

[0007] The backpack vacuum cleaner of the present invention is light-weight and significantly reduces the noise levels associated with the motor and air movement noise at the vacuum tools and exhaust while maintaining good system performance. The vacuum cleaner maintains large cross-sectional areas for exhaust flow, allowing sufficient air flow to provide the required cooling for the motor. The vacuum cleaner also directs the air flow to unique foam surfaces to obtain the required sound deadening.

Problems solved by technology

One of the complaints by workers and visitors in the office buildings or other commercial settings of vacuum cleaning is the noise.
This reduces the system performance to an unacceptable level and adds weight to the vacuum cleaner.
By restricting the flow path in this manner the motor is susceptible to overheating because it is not getting sufficient air for cooling.

Embodiment Construction

[0018] With reference to FIGS. 1-6, and initially FIGS. 1-3, an embodiment of a quiet backpack vacuum cleaner 100 will be described.

[0019] Although the quiet vacuum cleaner 100 is shown and described as a backpack vacuum cleaner, the features of the vacuum cleaner 100 that make it a quiet, high-performance vacuum cleaner may be applied to additional types of vacuum cleaners such as, but not by way of limitation, canister vacuum cleaners and upright vacuum cleaners.

[0020] After reading this description it will become apparent to one skilled in the art how to implement the invention in various alternative embodiments and alternative applications. However, although various embodiments of the present invention will be described herein, it is understood that these embodiments are presented by way of example only, and not limitation. As such, this detailed description of various alternative embodiments should not be construed to limit the scope or breadth of the present invention as set...

Abstract

A light-weight, quiet vacuum cleaner assembly for a backpack vacuum cleaner includes an air inlet for communicating with a vacuum cleaner hose and a filter; a vacuum motor for drawing air through the vacuum cleaner hose, air inlet, and filter; a quiet exhaust assembly module in communication with the vacuum motor for expelling and quieting exhaust from the vacuum motor, and wherein the vacuum cleaner assembly weighs 2-12 lbs. and includes a flow rate (CFM) to noise (dbA) ratio (flow rate / noise) of at least 0.6.

Description

BACKGROUND [0001] 1. Field of the Invention [0002] The present invention relates, in general, to vacuum cleaners, and, in particular, to backpack vacuum cleaners. [0003] 2. Background of the Invention [0004] It is well-known that vacuum cleaning efficiency has been improved through the use of backpack vacuum cleaners. A backpack vacuum cleaner includes a backpack assembly, similar to that used in a hiking backpack, where the vacuum cleaner assembly is carried by a backpack frame of the backpack assembly. A vacuum cleaner hose extends from a top of the vacuum cleaner assembly and is connected to a vacuum cleaner wand. A distal end of the vacuum cleaner wand includes a vacuum cleaner floor tool. In use, the cleaner carries the backpack vacuum cleaner on his or her back using the backpack assembly, and directs the vacuum cleaner tool for cleaning the floor surface through the wand. Historically, much of the cleaning performed using backpack vacuum cleaners such as that done in office b...
