Abstract
A hand vacuum cleaner has an information display device provided on a rear wall of the rear end of the hand vacuum cleaner.
Claims22
A hand vacuum cleaner having a front end, a rear end, an upper end and a lower end, the hand vacuum cleaner comprising:
- (a) an air flow path extending from a dirty air inlet to a clean air outlet, the dirty air inlet provided at the front end, wherein the air flow path comprises an inlet conduit extending from the dirty air inlet provided at a front end of the air inlet conduit to an air outlet at a rear end of the air inlet conduit, the air inlet conduit has an inlet conduit axis extending centrally through the inlet conduit from the dirty air inlet to the rear end of the air inlet conduit;
- (b) an air treatment assembly comprising an air treatment chamber positioned in the air flow path, the air treatment assembly having an air treatment assembly front end, an air treatment assembly rear end, an air treatment assembly axis extending centrally through the air treatment assembly from the air treatment assembly front end to the air treatment assembly rear end, an air treatment assembly air inlet and an air treatment assembly air outlet;
- (c) a suction motor positioned in the air flow path downstream of the air treatment assembly and upstream of the clean air outlet, the suction motor having a motor axis of rotation;
- (d) a pistol grip handle having a handle upper end, a handle lower end and a handle axis extending centrally through the pistol grip handle from the lower end of the handle to the upper end of the handle, wherein, an axis extending in a common direction with the air treatment assembly axis extends through the air treatment assembly air outlet and intersects the handle axis within the hand vacuum cleaner, and wherein the handle axis intersects the suction motor;
- and,
- (e) an information display device provided on a rear wall of the rear end of the hand vacuum cleaner,
- wherein the air treatment assembly axis extends in a common direction with the inlet conduit axis, and,
- wherein, in operation, the hand vacuum cleaner further comprises a pre-motor filter positioned in a pre-motor filter housing and air exits the pre-motor filter housing in a flow direction, and
- wherein the flow direction and the motor axis of rotation extend in the common direction.
