Abstract

A hand carryable surface cleaning apparatus is disclosed. The apparatus comprises a main body housing a suction motor, and a cyclone bin assembly. The cyclone bin assembly comprises a cyclone chamber and a dirt collection chamber. At least a portion of the dirt collection chamber may extend under at least a portion of the suction motor. The suction motor may be oriented at an angle to a vertical axis and a horizontal axis.

First claim

The invention claimed is:

1. A hand carryable surface cleaning apparatus comprising:
(a) a body housing a suction motor, the suction motor oriented forwardly and having a motor axis that defines a suction motor centerline;
(b) a cyclone bin assembly mounted to the body and comprising a cyclone chamber and a dirt collection chamber, wherein at least a portion of the dirt collection chamber extends under at least a portion of the suction motor, and wherein the cyclone chamber has a cyclone axis that defines a cyclone chamber centerline that is positioned forward of the suction motor centerline, and wherein the motor axis is oriented at an angle of between 30 degrees and 45 degrees relative to the cyclone axis; and,
(c) an air flow path extending from a dirty air inlet to a clean air outlet and including the suction motor and the cyclone bin assembly
wherein the dirt collection chamber has a recess provided on an upper surface of the dirt collection chamber for receiving a portion of the suction motor.

2. The hand carryable surface cleaning apparatus of claim 1 wherein the dirt collection chamber extends under all of the suction motor.

3. The hand carryable surface cleaning apparatus of claim 1 wherein the dirt collection chamber extends rearwardly of the cyclone chamber.

4. The hand carryable surface cleaning apparatus of claim 3 wherein the dirt collection chamber extends forwardly of the cyclone chamber.

5. The hand carryable surface cleaning apparatus of claim 3 wherein the cyclone chamber has a dirt outlet provided on a rearward side of the cyclone chamber.

6. The hand carryable surface cleaning apparatus of claim 1 wherein the dirt collection chamber comprises a stand for the hand carryable surface cleaning apparatus.

7. The hand carryable surface cleaning apparatus of claim 1 , wherein the at least a portion of the dirt collection chamber extends under at least a motor portion of the suction motor.

8. A hand carryable surface cleaning apparatus comprising:
(a) a body housing a suction motor, the suction motor oriented forwardly and having a motor axis that defines a suction motor centerline;
(b) an air treatment member mounted to the body and comprising a dirt collection chamber, wherein at least a portion of the dirt collection chamber extends under at least a portion of the suction motor and wherein the air treatment member has an axis that defines an air treatment centerline that is positioned forward of the suction motor centerline; and,
(c) an air flow path extending from a dirty air inlet to a clean air outlet and including the suction motor and the air treatment member
wherein a rearward portion of the dirt collection chamber has an upper surface that extends concurrently downwardly and rearwardly towards a rear of the hand carryable surface cleaning apparatus.

9. The hand carryable surface cleaning apparatus of claim 8 wherein the upper surface of the dirt collection chamber has a recess for receiving a portion of the suction motor.

10. The hand carryable surface cleaning apparatus of claim 8 wherein the air treatment member comprises a cyclone chamber.

11. The hand carryable surface cleaning apparatus of claim 8 , wherein the motor axis is oriented at an angle of between 30 degrees and 45 degrees relative to the cyclone axis.

12. A hand carryable surface cleaning apparatus comprising:
(a) a body housing a suction motor, the suction motor oriented forwardly and having a motor axis that defines a suction motor centerline;
(b) a cyclone bin assembly mounted to the body and comprising a cyclone chamber and a dirt collection chamber, wherein at least a portion of the dirt collection chamber extends under at least a portion of the suction motor and wherein the cyclone chamber has a cyclone axis that defines a cyclone chamber centerline that is positioned forward of the suction motor centerline, and wherein the motor axis is oriented at an angle of between 30 degrees and 45 degrees relative to the cyclone axis; and,
(c) an air flow path extending from a dirty air inlet to a clean air outlet and including the suction motor and the cyclone bin assembly
wherein the dirt collection chamber extends forwardly of the cyclone chamber.

13. The hand carryable surface cleaning apparatus of claim 12 wherein the dirt collection chamber has a recess for receiving a portion of the suction motor.

14. The hand carryable surface cleaning apparatus of claim 13 wherein the recess is provided on an upper surface of the dirt collection chamber.

15. A hand carryable surface cleaning apparatus comprising:
(a) a body housing a suction motor, the suction motor oriented forwardly and having a motor axis that defines a suction motor centerline;
(b) an air treatment member mounted to the body and comprising a dirt collection chamber, wherein at least a portion of the dirt collection chamber extends under at least a portion of the suction motor and wherein the air treatment member has an axis that defines an air treatment centerline that is positioned forward of the suction motor centerline, and wherein the motor axis is oriented at an angle of between 0 degrees and 90 degrees relative to the air treatment member axis;
(c) an air flow path extending from a dirty air inlet to a clean air outlet and including the suction motor and the air treatment member; and,
(d) a porous pre-motor filter media positioned in a pre-motor filter chamber that is located above the air treatment member and air exits upwardly from the air treatment member to the pre-motor filter chamber
wherein the air treatment member is removable as a sealed unit other than an air treatment member air inlet and an air treatment member air outlet.

16. The hand carryable surface cleaning apparatus of claim 15 wherein the air treatment member comprises a cyclone chamber.

17. The hand carryable surface cleaning apparatus of claim 15 , wherein the at least a portion of the dirt collection chamber extends under at least a motor portion of the suction motor.

18. A hand carryable surface cleaning apparatus comprising:
(a) a body housing a suction motor, the suction motor oriented forwardly and having a motor axis that defines a suction motor centerline;
(b) a cyclone bin assembly mounted to the body and comprising a cyclone chamber and a dirt collection chamber, wherein at least a portion of the dirt collection chamber extends under at least a portion of the suction motor and wherein the cyclone chamber has a cyclone axis that defines a cyclone chamber centerline that is positioned forward of the suction motor centerline; and,
(c) an air flow path extending from a dirty air inlet to a clean air outlet and including the suction motor and the cyclone bin assembly
wherein the body is provided with a handle comprising a hand grip portion adjacent a finger gap sized to receive the fingers of a user and wherein a portion of the suction motor is forward of a forward end of the hand grip portion.

19. The hand carryable surface cleaning apparatus of claim 18 , wherein the at least a portion of the dirt collection chamber extends under at least a motor portion of the suction motor.

20. The hand carryable surface cleaning apparatus of claim 18 , wherein the motor axis is oriented at an angle of between 30 degrees and 45 degrees relative to the cyclone axis.

21. A hand carryable surface cleaning apparatus comprising:
