Abstract

A hand carryable surface cleaning apparatus is disclosed. The apparatus comprises a main body housing a suction motor, and a cyclone bin assembly removably mounted to the main body. The cyclone bin assembly may be partially or wholly nested in the body when the cyclone bin assembly is mounted to the body. The cyclone bin assembly may be removably mounted to a lower surface of the main body. The cyclone bin assembly may be removably mounted as a sealed unit.

Claims

1. A hand carryable surface cleaning apparatus comprising:

(a) a body housing a suction motor and comprising a dirty air inlet;

(b) a cyclone bin assembly removably mounted to the body, the cyclone bin assembly is removable as a sealed unit other than the cyclone bin assembly air inlet and the cyclone bin assembly air outlet, the cyclone bin assembly comprising a cyclone bin assembly air inlet in air flow communication with the dirty air inlet when the cyclone bin assembly is mounted to the body, a cyclone chamber and a dirt collection chamber; 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,

wherein the cyclone bin assembly is at feast partially nested in the body when the cyclone bin assembly is mounted to the body, and

wherein a recess is provided in a lower side of the body in which the cyclone bin assembly is received.

2. The hand carryable surface cleaning apparatus of claim 1 wherein an upper portion of the cyclone bin assembly is received in the recess.

3. The hand carryable surface cleaning apparatus of claim 1 wherein an upper portion of the cyclone bin assembly is received in the recess and the cyclone bin assembly air inlet is provided at an upper end of the cyclone bin assembly.

4. The hand carryable surface cleaning apparatus of claim 3 wherein a cyclone bin assembly air outlet is provided at an upper end of the cyclone bin assembly.

5. The hand carryable surface cleaning apparatus of claim 4 wherein the body comprises a pre-motor filter positioned above the recess.

6. The hand carryable surface cleaning apparatus of claim 1 wherein the body comprises a conduit extending from the dirty air inlet to a conduit air outlet and the conduit extends linearly.

7. The hand carryable surface cleaning apparatus of claim 1 wherein the body comprises a conduit extending from the dirty air inlet to a conduit air outlet and the conduit air outlet extends at an angle to a direction of airflow through the conduit and the cyclone bin assembly air inlet extends in a mating angle.

8. The hand carryable surface cleaning apparatus of claim 1 wherein the body has a carry handle and the carry handle remains with the body when the cyclone bin assembly is removed.

9. A hand carryable surface cleaning apparatus comprising:

(a) a body housing a suction motor and comprising a dirty air inlet;

(b) a cyclone bin assembly removably mounted to the body, the cyclone bin assembly is removable as a sealed unit other than the cyclone bin assembly air inlet and the cyclone bin assembly air outlet, the cyclone bin assembly comprising a cyclone bin assembly air inlet in air flow communication with the dirty air inlet when the cyclone bin assembly is mounted to the body, a cyclone chamber and a dirt collection chamber; 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,

wherein the cyclone bin assembly is at least partially nested in the body when the cyclone bin assembly is mounted to the body, and

wherein the cyclone bin assembly air inlet is provided at an upper end of the cyclone bin assembly.

10. The hand carryable surface cleaning apparatus of claim 9 wherein a cyclone bin assembly air outlet is provided at an upper end of the cyclone bin assembly.

11. The hand carryable surface cleaning apparatus of claim 10 wherein an upper portion of the cyclone bin assembly is received in the recess, and the body comprises a pre-motor filter positioned above the recess.

12. A hand carryable surface cleaning apparatus comprising:

(a) a body housing a suction motor and comprising a dirty air inlet;

(b) a cyclone bin assembly removably mounted to a lower side of the body, the cyclone bin assembly is removable as a sealed unit other than the cyclone bin assembly air inlet and the cyclone bin assembly air outlet, the cyclone bin assembly comprising a cyclone bin assembly air inlet provided at an upper end of the cyclone bin assembly and in air flow communication with the dirty air inlet when the cyclone bin assembly is mounted to the body, a cyclone chamber and a dirt collection chamber; 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.

13. The hand carryable surface cleaning apparatus of claim 12 wherein a cyclone bin assembly air outlet is provided at an upper end of the cyclone bin assembly.

14. The hand carryable surface cleaning apparatus of claim 12 wherein the body comprises a pre-motor filter positioned above the cyclone bin assembly.

15. The hand carryable surface cleaning apparatus of claim 12 wherein the body comprises a conduit extending from the dirty air inlet to a conduit air outlet and the conduit air outlet extends at an angle to a direction of airflow through the conduit and the cyclone bin assembly air inlet extends in a mating angle.

16. The hand carryable surface cleaning apparatus of claim 12 wherein the body has a carry handle and the carry handle remains with the body when the cyclone bin assembly is removed.
