Hand carryable surface cleaning apparatus
A hand vacuum cleaner may have an air treatment member and a pre-motor filter downstream from the air treatment member. A suction motor and fan assembly may be is positioned downstream of and below the pre-motor filter, a post motor filter may be positioned downstream of the suction motor and fan assembly and in the lower end of the hand vacuum cleaner. A clean air outlet may be positioned below the suction motor and fan assembly whereby air travels downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.
1. A hand vacuum cleaner having a front end, a rear end, an upper end, a lower end and a handle, the hand vacuum cleaner comprising:
(a) an air flow passage extending from an air inlet to a clean air outlet, wherein the air inlet is provided at the upper end of the hand vacuum cleaner and comprises an inlet conduit having an inlet end, an outlet end and a central longitudinally extending inlet conduit axis extending from the inlet end of the inlet conduit to the outlet end of the inlet conduit, the inlet conduit axis is oriented substantially horizontally;
(b) an air treatment member downstream of the air inlet;
(c) a pre-motor filter downstream from the air treatment member, the pre-motor filter has an upper end and a lower end;
(d) a suction motor and fan assembly that is positioned downstream of the pre-motor filter, the suction motor and fan assembly having a central axis of rotation wherein the suction motor and fan assembly is positioned below the pre-motor filter and the central axis of rotation is oriented substantially vertically when the inlet conduit axis is oriented substantially horizontally whereby air travels downwardly from the pre-motor filter to and past the suction motor and fan assembly; and,
(e) a post motor filter positioned downstream of the suction motor and fan assembly and in the lower end of the hand vacuum cleaner,
wherein the clean air outlet is positioned below the suction motor and fan assembly whereby air travels downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.
2. The hand vacuum cleaner of claim 1 wherein the post motor filter is positioned below the suction motor and fan assembly.
3. The hand vacuum cleaner of claim 1 wherein a lower end of the post motor filter is positioned below a lower end of the suction motor and fan assembly.
4. The hand vacuum cleaner of claim 1 wherein the suction motor and fan assembly is provided in a suction motor and fan assembly housing and a lower end of the post motor filter is positioned below a lower end of the suction motor and fan assembly and below the handle.
5. The hand vacuum cleaner of claim 4 wherein the handle is positioned rearward of a rear end of the suction motor and fan assembly.
6. 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 passage extending from an air inlet to a clean air outlet;
(b) an air treatment member downstream of the air inlet;
(c) a pre-motor filter downstream from the air treatment member;
(d) a suction motor and fan assembly that is positioned downstream of and below the pre-motor filter;
(e) a post motor filter positioned downstream of the suction motor and fan assembly;
and,
(f) a handle having a longitudinally extending pistol-grip style hand grip portion having a longitudinally extending pistol-grip style hand grip portion axis that is parallel to the hand grip portion and is oriented substantially vertically, with an upper end of the pistol-grip style hand grip portion forward of a lower end of the pistol-grip style hand grip portion,
wherein the post motor filter is positioned below a lower end of the suction motor and fan assembly.
7. The hand vacuum cleaner of claim 6 wherein the post motor filter is provided in a post motor filter housing and, when the hand vacuum cleaner is placed on a horizontal surface with the pistol-grip style hand grip portion axis oriented substantially vertically, the hand vacuum cleaner rests on at least the post motor filter housing.
8. The hand vacuum cleaner of claim 6 wherein the handle is positioned rearward of a rear end of the suction motor and fan assembly.
9. A hand vacuum cleaner comprising:
(a) an air flow passage extending from an air inlet to a clean air outlet;
(b) an air treatment member downstream of the air inlet;
(c) a pre-motor filter downstream from the air treatment member;
(d) a suction motor and fan assembly provided in a suction motor and fan assembly housing and positioned downstream of the pre-motor filter;
(e) a post motor filter positioned downstream of the suction motor and fan assembly;
and,
(f) a handle having a longitudinally extending pistol-grip style hand grip portion having a longitudinally extending pistol-grip style hand grip portion axis that is parallel to the hand grip portion and is oriented substantially vertically, wherein a lower end of the handle is positioned rearward of a rear end of the suction motor and fan assembly,
wherein a lower end of the post motor filter is positioned below a lower end of the handle.
