Description
- The disclosure relates to surface cleaning apparatuses, such as vacuum cleaners. Particularly, the disclosure relates to upright surface cleaning apparatuses.
- The following is not an admission that anything discussed below is prior art or part of the common general knowledge of persons skilled in the art.
- Various constructions for surface cleaning apparatus such as vacuum cleaners are known. Currently, many surface cleaning apparatus are constructed using at least one cyclonic cleaning stage. The air is drawn into the vacuum cleaner through a dirty air inlet and conveyed to a cyclone inlet. The rotation of the air in the cyclone results in some of the particulate matter in the airflow stream being disentrained from the airflow stream. This material is then collected in a dirt collection chamber, which may be at the bottom of the cyclone or in a dirt collection chamber exterior to the cyclone chamber (see for example WO2009/026709 and U.S. Pat. No. 5,078,761). One or more additional cyclonic cleaning stages and/or filters may be positioned downstream from the cyclone.
- The following summary is provided to introduce the reader to the more detailed discussion to follow. The summary is not intended to limit or define the claims.
- According to one aspect, an upright surface cleaning apparatus is provided with a suction motor housing that includes a post motor filter chamber. The post motor filter chamber is positioned spaced from but facing the suction motor. The air accordingly will travel from the air treatment member or members to the suction motor inlet. The air will travel through the fan of the suction motor and then by or through the motor section to cool the motor. The air will then travel laterally, and possibly upwardly and laterally, to the post motor filter. This constructions permits a reduction in the size of the suction motor housing.
- Traditionally, upright surface cleaning apparatus have had large, bulky frames or upper housings. The upper housing has a recess for removably receiving a cyclone. The housing has also incorporated air flow passages (e.g., from a dirty air inlet to a cyclone inlet and from a cyclone outlet to a suction motor inlet). This structure increases the weight of an upright vacuum cleaner and also reduces the portability of an upright vacuum cleaner for the elderly or the infirm. A reduction in the size of the suction motor housing reduces the weight and increases the portability of the surface cleaning apparatus.
- In a preferred embodiment, the suction motor is mounted on the upright section of the vacuum cleaner (e.g., the portion that comprises the push handle) and is spaced from the floor cleaning head. Such a construction is advantageous as it permits the floor cleaning head to extend further under furniture (e.g., floor cleaning head may be passed under furniture until the bottom of the upright section contact the furniture). However, if the components of the vacuum cleaner (e.g., the motor and the cyclone housing) are too high on the handle, then the hand weight of the vacuum cleaner during operation will increase thereby decreasing the usability of the vacuum cleaner. Reducing the height of the suction motor housing permits the suction motor to be provided on the handle, thereby reducing the height of the floor cleaning head and increasing the ability of the floor cleaning head to clean under furniture. At the same time, the components on the vacuum cleaner may be mounted lower thereby reducing hand weight.
- According to this aspect, an upright surface cleaning apparatus comprises a floor cleaning head having a dirty air inlet, and an air flow passage extending from the dirty air inlet to a clean air outlet. An upright section is moveably mounted to the surface cleaning head between a storage position and an in use position. The upright section comprises a filtration member and a suction motor provided in the air flow passage. The suction motor has an air inlet end, an opposed distal end, and an air inlet direction. The upright section further comprises a motor housing. The motor housing comprises a motor section in which the suction motor is provided. The motor section has a first end at the air inlet end of the suction motor and an opposed second end at the distal end of the suction motor. An openable post motor filter chamber is provided in the motor housing and has an inlet end and an outlet end. At least a portion of the filter chamber is provided in the motor section. The inlet end includes a finger guard and the filter chamber has a direction of airflow that is transverse to the air inlet direction of the suction motor. A post motor HEPA filter is removably mounted in the filter chamber.
- The inlet end of the filter chamber may be positioned adjacent the suction motor. At least a portion of the inlet end of the filter chamber may be laterally spaced from and may face the suction motor.
- The surface cleaning apparatus may further comprise a pre-motor filter positioned at the air inlet end of the suction motor. The pre-motor filter may have a direction of airflow that is aligned with the air inlet direction of the suction motor.
- The filtration member may comprise a cyclone. The cyclone may comprise an air inlet and an air outlet, and the air outlet of the cyclone may be spaced from and may face the pre-motor filter. The air inlet end of the filter chamber may be spaced less than 3 inches from the suction motor, more specifically less than 1.5 inches from the suction motor.
- According to another aspect, another upright surface cleaning apparatus is provided. The surface cleaning apparatus comprises a floor cleaning head having a dirty air inlet. An air flow passage extends from the dirty air inlet to a clean air outlet. An upright section is moveably mounted to the surface cleaning head between a storage position and an in use position, and includes a motor housing. A filtration member and a suction motor are provided in the air flow path. The suction motor has an air inlet end, an opposed distal end, and an air inlet direction. An openable post motor filter chamber is provided in the motor housing and has an inlet end and an outlet end. At least a portion of the inlet end is laterally spaced from and faces the suction motor. The inlet end includes a finger guard. A post motor HEPA filter is removably mounted in the filter chamber.
- The inlet end of the filter chamber may be positioned adjacent the suction motor.
- The motor housing may comprise a motor section in which the suction motor is provided. The motor section may have a first end at the air inlet end of the suction motor and an opposed second end at the distal end of the suction motor. At least a portion of the filter chamber may be provided in the motor section.
- The surface cleaning apparatus may further comprise a pre-motor filter positioned at the air inlet end of the suction motor. The pre-motor filter may have a direction of airflow that is aligned with the air inlet direction of the suction motor.
- The filter chamber may have a direction of airflow that is transverse to the air inlet direction of the suction motor.
- The filtration member may comprise a cyclone. The cyclone may comprise an air inlet and an air outlet, and the air outlet may be spaced from and may face the pre-motor filter. For example, the air inlet end of the filter chamber may be spaced less than 3 inches from the suction motor, more specifically less than 1.5 inches from the suction motor.

In thecyclone chamber 150, the air flows within thecyclone wall 148 in a cyclonic pattern, and particulate matter is separated from the air. The particulate matter exits thecyclone chamber 150 through the first end 152, and settles in thedirt collection chamber 160. The air exits thecyclone chamber 150 through thecyclone air outlet 164, and enters themotor housing 122. - The
dirt collection chamber 160 may be emptied in any suitable manner. In the embodiment shown, thebottom wall 134 is pivotally mounted to thesidewall 130, and serves as an openable door. Thedirt collection chamber 160 may be emptied by removing thefiltration member housing 120 from thesuction motor housing 124, as described hereinabove, and pivoting thebottom wall 134 away from thesidewall 130. - Referring still to
FIG. 2 , themotor housing 122 houses thesuction motor 126, a pre-motor filter 176 (shown inFIGS. 5 and 6A and 6B) upstream of thesuction motor 126 and downstream of the cyclone 144, and apost-motor filter 178 downstream of thesuction motor 126 and upstream of theclean air outlet 104. - The
pre-motor filter 176 extends across theopen top 140 of themotor housing 122, and has anupstream side 180 that faces and is spaced from thecyclone air outlet 164, and an opposeddownstream side 182 that faces thebottom wall 138 of themotor housing 122. Thepre-motor filter 176 is supported within themotor housing 122 by an apertured support wall 184 (seen most clearly inFIG. 3 ), which extends across themotor housing 122. Thepre-motor filter 176 is sized to be generally snugly received within themotor housing 122, such that air entering themotor housing 122 from thecyclone air outlet 164 passes through thepre-motor filter 176 in a direction indicated by arrow A (i.e. the pre-motor filter has a direction of airflow indicated by arrow A). Thepre-motor filter 176 may be any suitable type of filter. Preferably, the pre-motor filter includes afoam layer 186 and a feltlayer 188. - Referring to
FIG. 4 , when thefiltration member housing 120 is lifted off of themotor housing 122, thepre-motor filter 176 is exposed, and may be removed, replaced, or cleaned. - Referring back to
FIG. 2 , thesuction motor 126 is housed within themotor housing 122, in amotor section 173. Themotor section 173 is beneath theapertured support wall 184. Themotor section 173 has afirst end 175 and an opposedsecond end 177. - The
suction motor 126 may be any suitable type of suction motor, and preferably has afan portion 199 and amotor portion 197. In the embodiment shown, thesuction motor 126 extends along a longitudinal axis 190 that is generally vertically extending. Thesuction motor 126 has anair inlet end 179, an opposed distal end 181, and an air inlet direction, indicated by arrow A3. Thefirst end 175 of themotor section 173 is at theair inlet end 179 of thesuction motor 126, and thesecond end 177 is at the distal end 181 of thesuction motor 126. Preferably, thepre-motor filter 176 is positioned at theair inlet end 179 of thesuction motor 126, and the direction of airflow of thepre-motor filter 176 is aligned with the air inlet direction of thesuction motor 126. - The
post motor filter 178 is housed in apost-motor filter chamber 183. In the example shown, the postmotor filter chamber 183 is entirely within themotor section 173. In alternate embodiments, only a portion of the postmotor filter chamber 183 may be within themotor section 173, or the postmotor filter chamber 183 may be outside of themotor section 173. Preferably at least a third, more preferably at least two thirds and most preferably at least 75% of the postmotor filter chamber 183 is positioned within themotor section 173. An advantage of this design is that the height of the motor housing may be shortened, this permits the suction motor, and other components positioned on top of the motor housing, to be located lower on the upper section but still spaced from the top of the floor cleaning head. - The post
motor filter chamber 183 has aninlet end 185, which is adjacent thesuction motor 126, and anoutlet end 187, which is adjacent theclean air outlet 104. Preferably, at least a portion of theinlet end 185 is laterally spaced from and faces thesuction motor 126. For example, theair inlet end 185 of thefilter chamber 183 may be spaced less than 3 inches from thesuction motor 126, and preferably less than 1.5 inches from the suction motor. The direction of airflow through postmotor filter chamber 183, indicated by arrow A4, is transverse to the air inlet direction of the suction motor, indicated by arrow A3. - The post
motor filter chamber 183 is preferably openable, and thepost-motor filter 178 is preferably removably mounted in the postmotor filter chamber 183. For example, as shown inFIG. 5 , theclean air outlet 104 may be defined in agrate 189 that is removably mountable to thesuction motor housing 122. For example, one ormore latch members 191 may be provided to removably latch thegrate 189 to thesuction motor housing 126. Alternately, thegrate 189 may be pivotally openable with respect to thesuction motor housing 126. When thegrate 189 is opened or removed from thesuction motor housing 122, thepost motor filter 178 may be removed from the postmotor filter chamber 183, and may optionally be replaced or cleaned, for example. - Referring to
FIGS. 5 , 6A, and 6B, theinlet end 185 of the postmotor filter chamber 183 includes afinger guard 191. The finger guard generally prevents or minimizes the risk of a users fingers contacting thesuction motor 126 when the postmotor filter chamber 183 is open and thepost motor filter 178 is removed from the postmotor filter chamber 183. Thefinger guard 191 may be of any suitable configuration. In the embodiment shown, thefinger guard 191 is in the form of a grate, which extends partially around thesuction motor 126 and is integral with thesuction motor housing 122. - The
post-motor filter 178 may be any suitable type of filter, such as a HEPA filter. - It is possible that in some instances, the airflow passage may become fully or partially clogged. For example, a large object, such as a ball of hair, may become lodged anywhere in the airflow passage, such as in the
floor cleaning head 106. For further example, thepre-motor filter 176 may become clogged with particulate matter. If this occurs, thesuction motor 126 may burn out. Referring still toFIG. 2 , a bleed-valve 101 is provided in themotor housing 122. If a clog occurs in the airflow passage, the pressure in themotor housing 122 will decrease. Thebleed valve 101 is preferably configured to open when the pressure decreases, and allow air to flow through themotor housing 122 to the clean air. - Various apparatuses or methods are described above to provide an example of each claimed invention. No example described above limits any claimed invention and any claimed invention may cover processes or apparatuses that are not described above. The claimed inventions are not limited to apparatuses or processes having all of the features of any one apparatus or process described above or to features common to multiple or all of the apparatuses described above.
