Abstract

A hand carryable surface cleaning apparatus is disclosed. The apparatus comprises a main body housing a suction motor. An air treatment member has an assembly air inlet provided at the upper end of the assembly. The assembly is removably mounted to the main body as a sealed unit.

First claim

The invention claimed is:

1. A handvac comprising:
(a) a handvac body housing a suction motor and comprising a dirty air inlet;
(b) a cyclone bin assembly removably mounted to the handvac body, the cyclone bin assembly comprising, when placed on a horizontal surface, an upper end, a lower end, a cyclone chamber, a cyclone bin assembly air inlet provided at the upper end of the cyclone bin assembly and a cyclone bin assembly air outlet, the cyclone bin assembly air inlet being in air flow communication with the dirty air inlet when the cyclone bin assembly is mounted to the handvac body, wherein the cyclone bin assembly is removable from the handvac body as a sealed unit other than the cyclone bin assembly air inlet and the cyclone bin assembly air outlet, wherein the cyclone bin assembly is removable in a downward direction, and wherein at least a portion of the cyclone bin assembly forms at least a portion of an exterior surface of the handvac when the cyclone bin assembly is mounted to the handvac body; and,
(c) an air flow path extending from the dirty air inlet to a clean air outlet and including the suction motor and the cyclone chamber.

2. The handvac of claim 1 wherein the cyclone bin assembly air outlet is provided at the upper end of the cyclone bin assembly.

3. The handvac of claim 1 wherein the cyclone bin assembly air inlet is an inlet of the cyclone chamber and cyclone bin assembly air outlet is the air out of the cyclone chamber.

4. The handvac of claim 1 wherein the cyclone bin assembly further comprises an additional cyclonic cleaning stage downstream from the cyclone chamber.

5. The handvac of claim 1 wherein the cyclone bin assembly has an uppermost wall and the cyclone bin assembly air outlet is located in the uppermost wall.

6. The handvac of claim 1 wherein the cyclone bin assembly further comprises a dirt collection chamber exterior to the cyclone chamber.

7. The handvac of claim 6 wherein the dirt collection chamber is positioned below the cyclone chamber.

8. The handvac of claim 6 wherein the cyclone chamber has a dirt outlet in communication with the dirt collection chamber and the dirt outlet is located at a lower end of the cyclone chamber.

9. The handvac of claim 6 wherein the cyclone chamber has a dirt outlet in communication with the dirt collection chamber and the dirt outlet is located at a middle height of the cyclone bin assembly.

10. A handvac comprising:
(a) a handvac body housing a suction motor and comprising a dirty air inlet;
(b) a removable air treatment member assembly mounted to the handvac body, the assembly comprising, when placed on a horizontal surface, an upper end, a lower end, an assembly air inlet provided at the upper end of the assembly and an assembly air outlet, the assembly air inlet being in air flow communication with the dirty air inlet when the assembly is mounted to the handvac body, wherein the assembly is removable from the handvac body as a sealed unit other than the assembly air inlet and the assembly air outlet, wherein the assembly is removable in a downward direction, and wherein at least a portion of the assembly forms at least a portion of an exterior surface of the handvac when the assembly is mounted to the handvac body; and,
(c) an air flow path extending from the dirty air inlet to a clean air outlet and including the suction motor and the air treatment member.

11. The handvac of claim 10 wherein the assembly air outlet is provided at the upper end of the assembly.

12. The handvac of claim 11 wherein assembly air inlet is an inlet of the chamber and assembly air outlet is the air out of the chamber.

13. The handvac of claim 10 wherein the removable air treatment member assembly includes a chamber in which air circulates.

14. The handvac of claim 10 wherein the assembly has an uppermost wall and the assembly air outlet is located in the uppermost wall.

15. The handvac of claim 10 wherein the assembly further comprises a dirt collection chamber exterior to the chamber.

16. The handvac of claim 15 wherein the dirt collection chamber is positioned below the chamber.

17. The handvac of claim 15 wherein the chamber has a dirt outlet in communication with the dirt collection chamber and the dirt outlet is located at a lower end of the chamber.

18. The handvac of claim 15 wherein the chamber has a dirt outlet in communication with the dirt collection chamber and the dirt outlet is located at a middle height of the assembly.
