Abstract

A surface cleaning apparatus comprises a filtration apparatus comprising a cyclone and an openable dirt collection chamber in communication with the cyclone dirt outlet. The dirt collection chamber has an openable end portion that comprises a wall that is intersected by the longitudinally extending axis, and when the end portion is in an open position, the cyclone chamber has an absence of any member having a larger diameter than the vortex finder whereby the dirt collection chamber and the cyclone are concurrently emptyable when the dirt collection chamber is opened.

Claims

1. A surface cleaning apparatus comprising:

(a) a surface cleaning nozzle having a dirty air inlet that is downwardly oriented;

(b) a filtration apparatus comprising a cyclone downstream from the dirty air inlet, the cyclone having a cyclone chamber, a cyclone air outlet, a dirt outlet, and a lower openable portion, wherein the lower openable portion of the cyclone comprises a cyclone dirt collection surface and the cyclone air outlet;

(c) a downwardly openable dirt collection chamber exterior to the cyclone chamber in communication with the dirt outlet, the dirt collection chamber having a lower openable end portion that comprises a dirt collection surface, and the lower end portion of the dirt collection chamber is openable concurrently with the lower openable portion of the cyclone;

(d) a suction motor; and

,

(e) a clean air outlet downstream from the suction motor.

2. The surface cleaning apparatus of claim 1 wherein the lower end portion is pivotally openable.

3. The surface cleaning apparatus of claim 1 wherein the dirt collection surface and the cyclone dirt collection surface comprise a pivoting bottom of the filtration apparatus.

4. The surface cleaning apparatus of claim 1 wherein the cyclone air outlet has an upstream end in the cyclone chamber and an absence of any filtration member in covering relationship thereto.

5. The surface cleaning apparatus of claim 1 wherein the dirt collection chamber is positioned around at least a portion of the cyclone.

6. The surface cleaning apparatus of claim 5 wherein the dirt collection chamber surrounds at least a portion of a sidewall of the cyclone.

7. The surface cleaning apparatus of claim 1 wherein the cyclone is inverted and the dirt outlet is in an upper portion of the cyclone.

8. The surface cleaning apparatus of claim 1 wherein the dirt collection chamber and the cyclone chamber are the first collection chambers downstream from the dirty air inlet for collecting material entrained in an air entering the dirty air inlet.

9. A hand held surface cleaning apparatus comprising:

(a) a main body having a top, a bottom and a nozzle with a dirty air inlet;

(b) a filtration apparatus provided on the main body and comprising a cyclone downstream from the dirty air inlet, the cyclone having a cyclone chamber, a cyclone air outlet, a cyclone air inlet aligned substantially with the entire nozzle, a dirt outlet and a lower openable portion, wherein the lower openable portion of the cyclone comprises a cyclone dirt collection surface;

(c) a downwardly openable dirt collection chamber in communication with the dirt outlet, the dirt collection chamber having a lower openable end portion that comprises a dirt collection surface, and the lower end portion of the dirt collection chamber is openable concurrently with the lower openable portion of the cyclone

(d) a suction motor; and

,

(e) a clean air outlet downstream from the suction motor.

10. The hand held surface cleaning apparatus of claim 9 wherein the dirt collection chamber is positioned around at least a portion of the cyclone.

11. The hand held surface cleaning apparatus of claim 9 wherein the conduit is a cyclone air outlet of the cyclone chamber.

12. The hand held surface cleaning apparatus of claim 9 wherein the lower openable portion further comprises the cyclone air outlet.

13. A hand held surface cleaning apparatus comprising:

(a) a main body having a top, a bottom, a nozzle with a dirty air inlet wherein the nozzle is directly connected to a bottom portion of the main body;

(b) a filtration apparatus provided on the main body and comprising a cyclone downstream from the dirty air inlet, the cyclone having a cyclone chamber, a cyclone air outlet, a cyclone air inlet provided in a bottom portion of the filtration apparatus, a dirt outlet and a lower openable portion, wherein the lower openable portion of the cyclone comprises a cyclone dirt collection surface;

(c) a downwardly openable dirt collection chamber in communication with the dirt outlet, the dirt collection chamber having a lower openable end portion that comprises a dirt collection surface, and the lower end portion of the dirt collection chamber is openable concurrently with the lower openable portion of the cyclone;

(d) a suction motor; and

,

(e) a clean air outlet downstream from the suction motor.

14. The hand held surface cleaning apparatus of claim 13 wherein the lower openable portion further comprises the cyclone air outlet.
