Abstract

A hand vacuum cleaner has an air flow path extending from a dirty air inlet provided at a front end of the hand vacuum cleaner to a clean air outlet, a main body housing a suction motor, and an air treatment member that is moveably mounted to the main body between an operating position and an emptying position. The hand vacuum cleaner also includes a post-motor filter housing, wherein a post-motor-filter is removably receivable in the post-motor filter housing, and wherein moving the air treatment member to the emptying position enables access to the post-motor-filter.

Claims (40)

1. A hand vacuum cleaner comprising:

(a) an air flow path extending from a dirty air inlet provided at a front end of the hand vacuum cleaner to a clean air outlet;

(b) a main body housing a suction motor;

(c) an air treatment member that is moveably mounted to the main body between an operating position and an emptying position, the air treatment member has a front end and a rear end with a central longitudinal axis extends between the front and rear ends; and,

(d) a post-motor filter housing,

wherein a post-motor-filter is removably receivable in the post-motor filter housing, and

wherein moving the air treatment member to the emptying position enables access to the post-motor-filter,

wherein the post-motor filter housing includes a removable housing portion that is secured in a closed position by a lock, the lock comprising an actuator and the actuator is not visible when the air treatment member is in the operating position.

2. The hand vacuum cleaner of claim 1 wherein the post-motor filter housing includes a removable housing portion, and the removable housing portion is only removable after the air treatment member is moved to the emptying position.

3. The hand vacuum cleaner of claim 1 wherein the removable housing portion comprises a portion of an outer surface of the main body.

4. The hand vacuum cleaner of claim 3 wherein the suction motor has a motor axis of rotation and the removable housing portion extends in a direction of the motor axis of rotation and is positioned radially outward of the suction motor.

5. The hand vacuum cleaner of claim 3 wherein the post-motor filter has a longest dimension in a direction of the central longitudinal axis and the post-motor filter is arcuate in cross-section in a plane transverse to the central longitudinal axis.

6. The hand vacuum cleaner of claim 5 wherein the post-motor filter is removable in a direction transverse to the central longitudinal axis.

7. The hand vacuum cleaner of claim 1 wherein the post-motor filter is removable in a direction transverse to the central longitudinal axis.

8. The hand vacuum cleaner of claim 1 wherein the post-motor filter has a longest dimension in a direction of the central longitudinal axis and the post-motor filter is arcuate in cross-section in a plane transverse to the central longitudinal axis.

9. The hand vacuum cleaner of claim 1 wherein the air treatment member comprises a cyclone having a cyclone axis of rotation and the actuator extends in a direction transverse to the cyclone axis of rotation.

10. A surface cleaning apparatus comprising:

(a) an air flow path extending from a dirty air inlet provided at a front end of the surface cleaning apparatus to a clean air outlet;

(b) a main body housing a suction motor;

(c) an air treatment member that is removably mounted to the main body between an operating position and an emptying position, the air treatment member has an air inlet, an air outlet, a front end and a rear end, wherein air travels through the air outlet in a flow direction; and,

(d) a post-motor filter housing,

wherein a post-motor-filter is removably receivable in the post-motor filter housing, and

wherein moving the air treatment member to the emptying position enables access to the post-motor-filter, and

wherein the post-motor filter is removable in a direction transverse to the flow direction, and

wherein the post-motor filter housing includes a removable housing portion that is part of an exterior surface of the surface cleaning apparatus and the removable housing portion is removable in a direction transverse to the flow direction.

11. The surface cleaning apparatus of claim 10 wherein the removable housing portion is only removable after the air treatment member is moved to the emptying position.

12. The surface cleaning apparatus of claim 10 wherein the removable housing portion is secured in a closed position by a lock, the lock comprising an actuator and the actuator is accessible after the air treatment member is moved to the emptying position.

13. The surface cleaning apparatus of claim 10 wherein the removable housing portion comprises a portion of an outer surface of the main body.

14. A surface cleaning apparatus comprising:

(a) an air flow path extending from a dirty air inlet provided at a front end of the surface cleaning apparatus to a clean air outlet;

(b) a main body housing a suction motor;

(c) an air treatment member that is moveably mounted to the main body between an operating position and an emptying position, the air treatment member has a front end and a rear end with a central longitudinal axis extending between the front and rear ends; and,

(d) a post-motor filter housing comprising a removable housing portion that is secured in a closed position by a lock, the lock comprising an actuator,

wherein a post-motor-filter is removably receivable in the post-motor filter housing, and wherein the actuator is an internal component of the surface cleaning apparatus when the air treatment member is the operating position.

15. The surface cleaning apparatus of claim 14 wherein the removable housing portion comprises a portion of an outer surface of the main body.

16. The hand vacuum cleaner of claim 14 wherein the suction motor has a motor axis of rotation and the removable housing portion is positioned radially outward of the suction motor.

17. The surface cleaning apparatus of claim 14 wherein the post-motor filter has a longest dimension in a direction of the central longitudinal axis and the post-motor filter is arcuate in cross-section in a plane transverse to the central longitudinal axis.

18. The surface cleaning apparatus of claim 17 wherein the post-motor filter is removable in a direction transverse to the central longitudinal axis.

19. The surface cleaning apparatus of claim 14 wherein the post-motor filter is removable in a direction transverse to the central longitudinal axis.

20. The surface cleaning apparatus of claim 19 wherein the post-motor filter has a longest dimension in a direction of the central longitudinal axis and the post-motor filter is arcuate in cross-section in a plane transverse to the central longitudinal axis.
