Abstract
A hand vacuum cleaner has a main body housing a suction motor, an air treatment member having a front end and a rear end with a central longitudinal axis extending between the front and rear ends and a bleed valve having a bleed air flow path that extends from a bleed air inlet to a bleed air outlet. The hand vacuum cleaner has right and left laterally opposed sides that are spaced apart in a direction transverse to the central longitudinal axis, and the bleed air inlet and the bleed air outlet are transversely spaced apart.
Claims20
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 having a front end and a rear end with a longitudinal axis extending between the front and rear ends, wherein the air flow path comprises an inlet conduit extending from the dirty air inlet to the air treatment member and the inlet conduit has an inlet conduit axis;
- (d) a bleed valve having a bleed air flow path that extends from a bleed air inlet to a bleed air outlet, and a bleed valve axis which is a long dimension of the bleed valve;
- and,
- (e) a handle,
- wherein the hand vacuum cleaner has a rear end axially spaced from the front end of the hand vacuum cleaner and first and second laterally opposed sides that are spaced apart in a direction transverse to the longitudinal axis,
- wherein, when the hand vacuum cleaner is oriented with the longitudinal axis extending horizontally, the bleed valve axis also extends horizontally and in the transverse direction, the transverse direction is also horizontal and air exits the bleed air outlet upwardly.

- (d) a bleed valve having a bleed air flow path that extends from a bleed air inlet to a bleed air outlet, and a bleed valve axis which is a long dimension of the bleed valve;
- and,
- (e) a handle,
- wherein the hand vacuum cleaner has a rear end axially spaced from the front end, an upper end, a lower end and first and second laterally opposed sides, and
- wherein, when the hand vacuum cleaner is oriented with the dirty air inlet at the upper end of the hand vacuum cleaner and with the longitudinal axis extending horizontally, the bleed valve axis also extends horizontally and in a direction transverse to the longitudinal axis, the bleed valve is positioned below the suction motor and air travels upwardly to the suction motor from the bleed air outlet.
