HAND CARRYABLE SURFACE CLEANING APPARATUS
A hand vacuum cleaner has a pre-motor filter comprising a longitudinally extending filter media having an open interior, an outer upstream wall, an inner downstream wall and a filter longitudinal axis wherein the longitudinal axis extends upwardly in a direction from the lower end to the upper end.
1 . A hand vacuum cleaner having an upper end and a lower end, the hand vacuum cleaner comprising:
(a) a suction motor and fan assembly having a suction motor axis of rotation;
(b) an air treatment member having a front end and a rear end and a central longitudinal axis extending between the front and rear ends; and,
(c) a pre-motor filter comprising a longitudinally extending filter media having an open interior, an outer upstream wall, an inner wall and a filter longitudinal axis wherein the longitudinal axis extends upwardly in a direction from the lower end to the upper end.
2 . The hand vacuum cleaner of claim 1 wherein air exits the pre-motor filter in the direction of the filter longitudinal axis.
3 . The hand vacuum cleaner of claim 2 wherein air travels upwardly from the pre-motor filter to an inlet of the suction motor.
4 . The hand vacuum cleaner of claim 1 wherein the suction motor is positioned above the pre-motor filter when the longitudinal axis is oriented to extend upwardly.
5 . The hand vacuum cleaner of claim 1 wherein the suction motor axis of rotation extends upwardly when the longitudinal axis is oriented to extend upwardly.
6 . The hand vacuum cleaner of claim 5 wherein the suction motor is positioned above the pre-motor filter when the longitudinal axis is oriented to extend upwardly.
7 . The hand vacuum cleaner of claim 1 wherein the suction motor axis of rotation extends generally vertically when the longitudinal axis is oriented to extend upwardly.
8 . The hand vacuum cleaner of claim 7 wherein the suction motor is positioned above the pre-motor filter when the longitudinal axis is oriented to extend upwardly.
9 . The hand vacuum cleaner of claim 1 wherein the suction motor is positioned above the pre-motor filter when the longitudinal axis is oriented to extend upwardly.
10 . The hand vacuum cleaner of claim 1 wherein the suction, motor is positioned forward of the pre-motor filter when the longitudinal axis s oriented to extend upwardly.
11 . The hand vacuum cleaner of claim 10 wherein the suction motor axis of rotation extends generally horizontally when the longitudinal axis is oriented to extend upwardly.
12 . The hand vacuum cleaner of claim 1 wherein the suction motor axis of rotation extends generally horizontally when the longitudinal axis is oriented to extend upwardly.
13 . The hand vacuum cleaner of claim 1 wherein the central longitudinal axis extends generally horizontally when the longitudinal axis is oriented to extend upwardly.
14 . The hand vacuum cleaner of claim 13 wherein the air treatment member comprises a cyclone and the central longitudinal axis is a cyclone axis.
15 . The hand vacuum cleaner of wherein the longitudinal axis intersects the filter media twice.
16 . The hand vacuum cleaner of claim 1 wherein the outer wall comprises an upstream filter wall and the inner wall comprises a downstream filter wall.
17 . The hand vacuum cleaner of claim 1 wherein the filter media is generally annular in transverse section.
18 . The hand vacuum cleaner of claim 1 furthers comprising an inlet conduit extending from a dirty air inlet to the air treatment member and having a passage having an inlet conduit axis wherein the inlet conduit axis is positioned above the pre-motor filter.
19 . The hand vacuum cleaner of claim 18 wherein the inlet conduit axis intersects the suction motor.
20 . The hand vacuum cleaner of claim 1 further comprising an inlet conduit extending from a dirty air inlet to the air treatment member and having a passage having an inlet conduit axis that intersects the suction motor.
21 . The hand vacuum cleaner of claim 1 further comprising a handle that houses at least one energy storage member, wherein the handle is removably mounted to the hand vacuum cleaner.
22 . The hand vacuum cleaner of claim 21 wherein the handle houses the at least one energy storage member in a lower portion thereof.
