Abstract
A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter and in an upper end of the hand vacuum cleaner. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner. The clean air outlet may be positioned below the suction motor and fan assembly whereby air may travel generally downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.
Claims27
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;
- (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 the pre-motor filter and in the upper end of the hand vacuum cleaner, the suction motor and fan assembly having a central axis of rotation;
- 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, and
- wherein the central axis of rotation is oriented upwardly, the suction motor and fan assembly has a lower air inlet whereby air exits an upper end of the suction motor and fan assembly.
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;
- (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 the pre-motor filter and in the upper end of the hand vacuum cleaner, the suction motor and fan assembly having a central axis of rotation;
- 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, and
- wherein air travels downstream from the suction motor and fan assembly, through the handle to the post motor filter.
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;
- (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 the pre-motor filter and in the upper end of the hand vacuum cleaner, the suction motor and fan assembly having a central axis of rotation;
- 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, and
- wherein the post motor filter is positioned in the handle.
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 downstream of the pre-motor filter, the suction motor and fan assembly having a central axis of rotation;
- (e) a post motor filter positioned downstream of the suction motor and fan assembly and in the lower end of the hand vacuum cleaner;
- and,
- (f) a handle having a hand grip portion that extends upwardly and forwardly, the hand grip portion comprising a down flow passage, an upper end of the air flow passage is downstream from the suction motor and fan assembly and a lower end of the air flow passage is upstream of the clean air outlet whereby air travels downwardly through the down flow passage to the clean air outlet.
