Abstract
A hand vacuum cleaner has a cyclone unit and a pistol grip handle. The cyclone unit comprises a cyclone chamber with a cyclone axis of rotation extending between the front and rear ends of the cyclone chamber. When the hand vacuum cleaner is oriented with the cyclone axis of rotation extending horizontally, the inlet conduit is located at a lower side of the hand vacuum cleaner, the pistol grip handle is provided on a lower side of the main body and the pistol grip handle extends upwardly from a lower end of the pistol grip handle to an upper end of the pistol grip handle.
Claims19
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, wherein the dirty air inlet comprises an inlet conduit;
- (b) a main body housing a suction motor that is positioned in the air flow path, the suction motor having a motor axis of rotation;
- (c) a cyclone unit comprising a cyclone provided in the air flow path, the cyclone comprising a cyclone chamber having a cyclone air inlet, a cyclone air outlet, a cyclone chamber front end, a cyclone chamber rear end, a cyclone axis of rotation extending between the front and rear ends of the cyclone chamber, and a sidewall located between the cyclone chamber front end and the cyclone chamber rear end;
- (d) a pre-motor filter housing which, in operation, houses a pre-motor filter, the pre-motor filter housing is positioned rearward of the cyclone chamber wherein, in operation, the pre-motor filter faces the cyclone air outlet;
- (e) an energy storage member pack containing a plurality of energy storage members wherein, in operation, the plurality of energy storage members extend in a row that extends generally transverse to the cyclone axis of rotation and the energy storage member pack is positioned rearward of the pre-motor filter and,
- (f) a pistol grip handle provided on an axially extending wall of the main body, wherein, when the hand vacuum cleaner is oriented with the cyclone axis of rotation extending horizontally, the pistol grip handle is provided on a lower side of the main body and the pistol grip handle extends upwardly from a lower end of the pistol grip handle to an upper end of the pistol grip handle, and
- wherein, in operation when the hand vacuum cleaner is oriented with the cyclone axis of rotation extending horizontally, a first axis that extends in a common direction with the cyclone axis of rotation extends through the cyclone chamber, the pre-motor filter housing and the suction motor and exterior to the energy storage member pack.
