Handheld surface cleaning apparatus
A hand vacuum cleaner has an air flow path extending from a dirty air inlet to a clean air outlet and a suction motor positioned in the air flow path. A cyclone chamber positioned in the air flow path has a cyclone air inlet and a cyclone air outlet. At least one energy storage member is positioned in an energy storage chamber having an energy storage chamber wall. The cyclone air outlet faces the energy storage chamber wall whereby air exiting the cyclone chamber impinges on the energy storage chamber wall.
1. A hand vacuum cleaner having a front end, a rear end, an upper end, a lower end, and first and second laterally spaced apart sides, and comprising:
(a) an air flow path extending from a dirty air inlet to a clean air outlet;
(b) a cyclone chamber positioned in the air flow path and having a cyclone air inlet, a cyclone air outlet, and a cyclone axis of rotation;
(c) a suction motor housing having a suction motor, the suction motor is positioned in the air flow path upstream of the clean air outlet; and,
(d) a plurality of energy storage members positioned in an energy storage chamber
wherein the energy storage chamber is exterior to a handle and spaced from the suction motor housing, and the plurality of energy storage members are mounted to one side of the suction motor housing, and
wherein a portion of the air flow path upstream of the suction motor is defined in part by a wall portion, the wall portion is in thermal communication with the energy storage chamber whereby air travelling through the portion of the air flow path upstream of the suction motor travels along the wall portion and cools the wall portion.
2. The hand vacuum cleaner of claim 1 wherein the cyclone axis of rotation extends generally in a forward/rearward direction.
3. The hand vacuum cleaner of claim 1 wherein the at least one energy storage member comprises a plurality of energy storage members wherein at least some of the plurality of energy storage members are arranged one above another in a generally upwardly extending configuration when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner.
4. The hand vacuum cleaner of claim 3 wherein the energy storage members arranged one above another comprise longitudinally extending members each having a longitudinal axis that extends laterally.
5. The hand vacuum cleaner of claim 3 wherein the cyclone axis of rotation intersects a volume defined by the generally upwardly extending configuration of energy storage members.
6. The hand vacuum cleaner of claim 5 wherein the cyclone axis of rotation extends generally in a forward/rearward direction.
7. The hand vacuum cleaner of claim 1 wherein the at least one energy storage member is removably receivable in the energy storage chamber.
8. The hand vacuum cleaner of claim 7 wherein the at least one energy storage member comprises a battery pack that is removably receivable in the energy storage chamber.
9. The hand vacuum cleaner of claim 1 wherein the wall portion faces the cyclone air outlet.
10. The hand vacuum cleaner of claim 9 wherein the portion of the air flow path extends generally upwardly from the cyclone air outlet to the suction motor when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner.
11. The hand vacuum cleaner of claim 10 wherein the suction motor is positioned above the cyclone axis of rotation when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner.
12. The hand vacuum cleaner of claim 9 wherein the portion of the air flow path extends generally downwardly from the cyclone air outlet to the suction motor when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner.
13. The hand vacuum cleaner of claim 12 wherein the suction motor is positioned below the cyclone axis of rotation when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner.
14. The hand vacuum cleaner of claim 1 wherein the handle has a hand grip portion that extends upwardly and forwardly when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner wherein the handle is positioned rearward of the at least one energy storage member.
15. The hand vacuum cleaner of claim 14 wherein the at least one energy storage member comprises a plurality of energy storage members wherein at least some of the plurality of energy storage members are arranged one above another in a generally upwardly extending configuration when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner.
16. The hand vacuum cleaner of claim 15 further comprising a finger gap positioned between the handle and the energy storage chamber.
17. The hand vacuum cleaner of claim 1 wherein the energy storage chamber is provided in a volume in the hand vacuum cleaner and the suction motor is located exterior to the volume.
18. The hand vacuum cleaner of claim 1 , wherein the plurality of energy storage members are positioned underneath the suction motor.
19. The hand vacuum cleaner of claim 1 , wherein the plurality of energy storage members are positioned forward of the suction motor.
20. The hand vacuum cleaner of claim 1 , wherein the plurality of energy storage members are positioned underneath and forward of the suction motor.
