Abstract
A hand vacuum cleaner has a hand vacuum cleaner axis that extends centrally from a front end of the hand vacuum cleaner rearwardly to a rear end of the hand vacuum cleaner. The hand vacuum cleaner has a cyclone assembly including a cyclone chamber and a dirt collection chamber. A line that extends in a common horizontal direction with the hand vacuum cleaner axis extends through the cyclone chamber and the dirt collection chamber.
Claims24
A hand vacuum cleaner comprising:
- (a) an air flow path from a dirty air inlet, which is provided at a front end of the hand vacuum cleaner, to a clean air outlet, which is positioned rearward of the dirty air inlet, wherein a hand vacuum cleaner axis extends centrally from the front end of the hand vacuum cleaner rearwardly to a rear end of the hand vacuum cleaner;
- (b) a cyclone assembly comprising:
- (i) a cyclone chamber having an upper end, a lower end, a cyclone chamber sidewall extending between the upper and lower ends of the cyclone chamber, a cyclone air inlet, a cyclone air outlet provided at the upper end of the cyclone chamber, a dirt outlet provided at the lower end of the cyclone chamber and a cyclone axis of rotation, wherein the cyclone axis of rotation extends generally transverse to the hand vacuum cleaner axis;
- and
- (ii) a dirt collection chamber exterior to the cyclone chamber wherein, in operation, dirt separated from air in the cyclone chamber enters the dirt collection chamber through the dirt outlet;
- (c) a motor and fan assembly provided in a motor housing, the motor and fan assembly having a motor axis of rotation;
- and,
- (d) a handle,
- wherein a line that extends in a common horizontal direction with the hand vacuum cleaner axis extends through the cyclone chamber and the dirt collection chamber.
