Abstract

A hand vacuum cleaner has an inlet conduit that is removably connectable to an accessory tool. An accessory power coupler extends in the same direction as the inlet conduit and is positioned laterally to one side of the inlet conduit The accessory power coupler has electrical connectors, wherein the electrical connectors of the accessory power coupler are inter-engaged with compatible electrical connectors provided on the accessory tool.

Claims

1. A hand vacuum cleaner having a front end, a rear end, an upper end, a lower end spaced apart from the upper end in a vertical direction, and first and second sides that are literally spaced apart in a horizontal direction, the hand vacuum cleaner comprises:

(a) a main body having a front face;

(b) an inlet conduit located at the upper end and extending forwardly from the front face, the inlet conduit having a dirty air inlet, the inlet conduit being removably connectable to an accessory tool;

(c) an air flow path extending from the dirty air inlet to a clean air outlet;

(d) an air treatment member and a suction motor positioned in the air flow path, a portion of the air treatment member is positioned at the lower end;

(e) a handle provided rearward of the inlet conduit; and

,

(f) an accessory power coupler extending forwardly from the front face and positioned laterally to one side of the inlet conduit, the accessory power coupler having electrical connectors,

wherein the electrical connectors of the accessory power coupler are inter-engageable with compatible electrical connectors provided on the accessory tool.

2. The hand vacuum cleaner of claim 1 wherein the accessory power coupler extends parallel to the inlet conduit.

3. The hand vacuum cleaner of claim 1 wherein the accessory power coupler is shorter than the inlet conduit.

4. The hand vacuum cleaner of claim 1 wherein the accessory tool is a rigid air flow conduit.

5. The hand vacuum cleaner of claim 1 wherein the accessory power coupler is positioned adjacent to the inlet conduit.

6. The hand vacuum cleaner of claim 1 wherein the accessory power coupler comprises three electrical connectors.

7. The hand vacuum cleaner of claim 1 wherein the accessory power coupler comprises a male connector.

8. A hand vacuum cleaner having a front end, a rear end, an upper end spaced apart from the upper end in a vertical direction, a lower end and first and second sides that are laterally spaced apart in a horizontal direction, the hand vacuum cleaner comprises:

(a) an inlet conduit provided on the front end, the inlet conduit having a dirty air inlet, the inlet conduit being removably connectable to an accessory tool;

(b) an air flow path extending from the dirty air inlet to a clean air outlet;

(c) an air treatment member and a suction motor positioned in the air flow path;

(d) a handle provided rearward of the inlet conduit, the handle having an upper end and a lower end and extending generally parallel to the vertical direction; and

,

(e) an accessory power coupler positioned laterally to one side of the inlet conduit,

wherein the accessory power coupler is inter-engageable with compatible electrical connectors provided on the accessory tool.

9. The hand vacuum cleaner of claim 8 further comprising a main body having a front face and the inlet conduit and the accessory power coupler extend forwardly from the front face.

10. The hand vacuum cleaner of claim 8 wherein the accessory power coupler extends parallel to the inlet conduit.

11. The hand vacuum cleaner of claim 8 wherein the accessory power coupler is shorter than the inlet conduit.

12. The hand vacuum cleaner of claim 8 wherein the accessory tool is a rigid air flow conduit.

13. The hand vacuum cleaner of claim 8 wherein the accessory power coupler is positioned adjacent to the inlet conduit.

14. The hand vacuum cleaner of claim 8 wherein the accessory power coupler comprises a set of electrical connectors.

15. The hand vacuum cleaner of claim 8 wherein the accessory power coupler comprises three electrical connectors.

16. The hand vacuum cleaner of claim 8 wherein the accessory power coupler comprises a male connector.

17. The hand vacuum cleaner of claim 8 wherein the accessory power coupler is positioned above a front openable door of a dirt collection region.
