Abstract

A hand-held vacuum cleaner includes a housing having first and second half housing elements. The housing has a handle and a nozzle. A motor is mounted within the housing for driving a shaft. A fan is mounted on the shaft for rotation therewith. A selectively separable bag assembly is mounted on the housing. A working air channel is formed within the housing for communicating the nozzle with the bag assembly. The air channel terminates in a working air outlet chute positioned within the bag assembly at its open upper end. The shaft is positioned within the housing generally normal to the direction of air flow within the working air channel.

Claims

1. A hand-held vacuum cleaner including a housing comprising mating first and second half housing elements, said housing having a handle and a nozzle, a motor mounted within the housing for driving a shaft, said shaft extending within said housing in a substantially vertically upward direction when the cleaner is in a position to clean a horizontal surface, a fan mounted on said shaft for rotation therewith, a selectively separable bag assembly mounted on said housing in spaced relation relative to said nozzle along the horizontal axis of the cleaner, a rotating brush mounted within the nozzle, drive means connecting said shaft to said brush for rotationally driving said brush, means defining a working air channel within said housing communicating said nozzle with said bas assembly, a first portion of said working air channel directing said working air and entrained debris substantially parallel to the flow path of debris thrown from said rotating brush, and into the inlet of said fan, the outlet of said fan directing the air and entrained debris into a second portion of said working air channel, said second portion of said working air channel having an initial radially extending section communicating directly with said fan outlet and a second section extending upwardly within said housing and terminating at the inlet into said bag assembly, said inlet into said bag assembly being positioned adjacent the top wall of the bag of said assembly.

2. A hand-held vacuum cleaner in accordance with claim 1 wherein the second section of said second portion of said air channel includes a substantially arcuate wall for directing the working air and entrained debris towards the rear of said bag assembly.

3. A hand-held vacuum cleaner in accordance with claim 2 wherein the housing includes a removable bottom wall member and said drive means comprises an endless belt, removal of said bottom wall member from said housing providing access for enabling the user of the cleaner to replace said belt.

4. A hand-held vacuum cleaner in accordance with claim 1 wherein the housing includes a removable bottom wall member and said drive means comprises an endless belt, removal of said bottom wall member from said housing providing access for enabling the user of the cleaner to replace said belt.
