Abstract
A hand vacuum cleaner has an air flow path extending from a dirty air inlet to a clean air outlet. An air treatment member and suction motor are positioned in the air flow path. The air treatment member is provided at the front end of the hand vacuum cleaner and has an air outlet provided at the rear end of the air treatment member. A pre-motor filter housing is provided rearward of the air treatment member. A pistol grip handle has an upper end that is mounted to the pre-motor filter housing.
Claims27
A hand vacuum cleaner having a front end and a rear end, the hand vacuum cleaner comprising:
- (a) an air flow path extending from a dirty air inlet to a clean air outlet with a suction motor provided in the air flow path;
- (b) an air treatment member provided in the air flow path at the front end of the hand vacuum cleaner, the air treatment member having an upper end, a lower end, a front end, a rear end, an air inlet and an air outlet, wherein the air outlet is provided at the rear end of the air treatment member;
- (c) a pre-motor filter housing, which in operation, houses a pre-motor filter, wherein the pre-motor filter comprises a porous physical filter media and is provided downstream of the air treatment member;
- (d) a main body comprising the suction motor;
- and,
- (e) a pistol grip handle having an upper end that is mounted to the main body, a lower end, a hand grip portion between the upper and lower ends of the handle, a hand grip portion front side, a hand grip portion rear side, a central handle axis extending centrally through the hand grip portion from a lower end of the hand grip portion to an upper end of the hand grip portion and a rear handle axis that extends along the hand grip portion rear side, wherein the central handle axis extends through the pre-motor filter but not the suction motor and wherein the rear handle axis extends through the hand vacuum cleaner forward of the suction motor,
- wherein the air flow path comprises an inlet conduit extending from the dirty air inlet to the air inlet of the air treatment member, the inlet conduit having an inlet, a rearwardly positioned outlet and a central inlet conduit axis extending centrally through the conduit from the inlet of the conduit to the outlet of the conduit and the inlet conduit axis intersects the pre-motor filter.

A hand vacuum cleaner having a front end and a rear end, the hand vacuum cleaner comprising:
- (a) an air flow path extending from a dirty air inlet to a clean air outlet with a suction motor provided in the air flow path;
- (b) an air treatment member provided in the air flow path at the front end of the hand vacuum cleaner, the air treatment member having an upper end, a lower end, a front end, a rear end, an air inlet and an air outlet, wherein the air outlet is provided at the rear end of the air treatment member;
- (c) a main body comprising a pre-motor filter housing and the suction motor, wherein in operation the pre-motor filter housing houses a pre-motor filter, the pre-motor filter comprises a porous physical filter media and a rear end of the pre-motor filter housing is provided rearward of the air treatment member, wherein the suction motor is positioned rearward of the pre-motor filter;
- and,
- (d) a pistol grip handle having an upper end that is mounted to the main body and a longitudinally extending hand grip portion wherein a central longitudinal axis extends centrally through a longitudinal length of the hand grip portion, wherein the central longitudinal axis extends through the pre-motor filter but not the suction motor,
- wherein the air flow path comprises an inlet conduit extending from the dirty air inlet to the air inlet of the air treatment member, the inlet conduit having an inlet, a rearwardly positioned outlet and a central inlet conduit axis extending centrally through the conduit from the inlet of the conduit to the outlet of the conduit and the inlet conduit axis intersects the pre-motor filter but not the suction motor.
