Abstract

A horizontal canister vacuum having a cover removably attached to the open end of a canister having a motor/fan assembly affixed thereto and cooperating with an air outlet to evacuate air from the interior cavity. A plurality of wheels provided for solidly supporting the canister and attached cover in a horizontal orientation when placed upon a flat surface and wherein accumulated dust particles may be emptied from the vacuum cleaner by removing the cover from the canister when the vacuum cleaner is positioned in a vertical orientation. A clam-shell configuration is provided for packaging the motor/fan assembly to direct air flow through the assembly for cooling thereof.

Claims

1. A vacuum cleaner comprising:

an elongated canister having a wall defining an interior cavity with an open top;

a cover removably attachable to the canister open top;

an air inlet in fluid communication with the canister interior cavity including means for removably attaching a conduit thereto;

a motor/fan assembly affixed to the cover in cooperation with the open top and including a fan intake in communication with the interior cavity and an air outlet for evacuating air from the interior cavity;

a filter element oriented within the canister dividing the internal cavity into a first region bounded by the cavity walls, the filter element and the cover, with the first region in direct communication with the air inlet, and a second region in fluid communication with the fan intake, wherein the second region is separated from the first region by the filter element;

wherein the motor/fan assembly includes an armature and fan affixed to one another along a common axis, and two substantially complementary housing members which cooperate with one another along a common plane extending through the axis of the armature and fan, the housing members defining therebetween an armature cavity and an air outlet which is longitudinally spaced from the armature cavity; and

the fan intake is situated outside of the two housing members along the axis and in fluid communication which the armature cavity so that air evacuated from the canister second region is pumped by the fan into the armature cavity and out through the air outlet.

2. The vacuum cleaner of claim 1 wherein the air outlet is aligned along the motor armature and fan axis.

3. The vacuum cleaner of claim 1 further comprising a plurality of wheels affixed to the canister and the cover for stablilizers supporting the vacuum cleaner in a substantially horizintal orientation and wherein the air inlet is located in the uppermost portion of the cover when the vacuum cleaner is positioned in said horizintal orientation.

4. The vacuum cleaner of claim 3 further comprising a pair of handles affixed to the cover, one being located along the outermost portion of the cover when the vacuum is in the horizontal orientation and the other handle positioned below and opposite thereto.

5. The vacuum cleaner of claim 1 wherein the fan/motor assembly further comprising a plurality of vanes for directing airflow from the fan through the motor assembly toward the air outlet.

6. The vacuum cleaner of claim 1 wherein the cover further comprising a molded bag support integrally formed in the cover, surrounding the fan inlet.

7. The vacuum cleaner of claim 6 wherein the filter element further comprising a paper bag attached to the molded bag support by means of a rubber band.

8. The vacuum cleaner of claim 1 wherein the air intake and the air outlet are coaxially aligned.
