Abstract
Description
- The disclosure relates to surface cleaning apparatuses, such as vacuum cleaners. Particularly, the disclosure relates to a convertible upright surface cleaning apparatus.
- 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, a convertible upright surface cleaning apparatus that has a cleaning unit that is removable for above floor cleaning or cleaning while hand held is provided. The cleaning unit comprises a suction motor and one or more air treatment members. The cleaning unit is electrically operable, e.g., operable when plugged into the AC outlet of a house. The floor cleaning head of the upright surface cleaning apparatus is electrically powered (e.g., an electrically powered rotatable brush associated with the dirty air inlet of the floor cleaning head). An electrically conductive member extends from the cleaning unit to the floor cleaning head so that the floor cleaning head is powered by the electrical source of the cleaning unit. Accordingly, when the cleaning unit is removed, the source of electricity is disconnected from the floor cleaning head. This source must be reconnected when the cleaning unit is mounted on the surface cleaning apparatus. This connection is preferably made automatically when the cleaning unit is mounted on the surface cleaning apparatus. Accordingly the surface cleaning apparatus may include an alignment mechanism to align the cleaning unit on an upper section (e.g., the handle) of the surface cleaning unit when the cleaning unit is mounted on the surface cleaning unit.
- 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, in the absence of an alignment member a user may have difficulty positioning the cleaning unit such that an electrical connection is automatically completed as the cleaning unit is mounted to the upper section.

Thepre-motor filter 176 is supported within thesuction motor housing 122 by an apertured support wall 184 (seen most clearly inFIG. 3 ), which extends across thesuction motor housing 122. Thepre-motor filter 176 is sized to be generally snugly received within thesuction motor housing 122, such that air entering thesuction motor housing 122 from thecyclone air outlet 164 passes through thepre-motor filter 176, in a direction 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 thesuction motor 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 thesuction motor housing 122 beneath theapertured support wall 184. Thesuction motor 126 may be any suitable type of suction motor. In the embodiment shown, thesuction motor 126 extends along a longitudinal axis 190 that is generally vertically extending. - The post motor filter is housed in the post

The plug 135 is inserted into the socket 137 as theupper section 105 is mounted to thetubular support member 112 of thefloor cleaning head 106, and is removed from the socket as theupper section 105 is lifted off of thetubular support member 112 of thefloor cleaning head 106. - In alternate embodiments, other types of electrical connectors may be used. Further, the electrically
conductive member 129 may comprise a socket, and the cleaning unit may comprise a plug. - Referring back to
FIG. 5 , in order to re-mount theupper section 110 to thefloor cleaning head 106, thebackbone 114 may be lowered onto thetubular support member 112, such that thetubular support member 112 is received in thebackbone 114, and thelatch member 127 may be latched. Preferably, the electricallyconductive member 129 is automatically connected to thecleaning unit 110 when theupper section 105 is mounted to thefloor cleaning head 106. That is, when theupper section 105 is lowered onto thetubular support 112, the plug 135 is preferably automatically inserted into thesocket 138. In order to reconnect the plug 135 and socket 137 when lowering theupper section 105, the plug 135 and socket 137 must be aligned. That is, theupper section 105 must at a preset orientation with respect to thefloor cleaning head 106, so that the plug 135 can be inserted into the socket 137 when theupper section 105 is lowered on to thetubular support member 112. Referring toFIG. 8 , in order to achieve the preset orientation, analignment member 139 is provided on thefloor cleaning head 106. Thealignment member 139 requires theupper section 105 to be in the preset orientation when mounted on thefloor cleaning head 106. - Referring still to
FIG. 8 , thealignment member 139 comprisesguide members 141 provided on thefloor cleaning head 106, and theguide members 141 interact with theupper section 105 as thecleaning unit 110 is mounted to theupper section 105. Specifically, theguide members 141 comprisemale engagement members 143 in the form of longitudinally extending splines on the exteriortubular support member 112. Further,female engagement members 145 are provided on thebackbone 114 of theupper section 105. Thefemale engagement members 145 are in the form of longitudinally extending slots on the interior of thebackbone 114. Thefemale engagement members 145 are separated byabutment members 147. Themale engagement members 143 are slideably engageable with thefemale engagement members 145. The male 143 and female 145 engagement members are positioned so that thetubular support member 112 may generally only be inserted into thebackbone 114 when theupper section 105 is at the preset orientation. Particularly, referring toFIG. 8 , in the orientation shown, theupper section 105 is not at the preset orientation, and themale engagement members 143 are not aligned with thefemale engagement members 145. Accordingly, thetubular support member 112 may not be inserted into thebackbone 114, because themale engagement members 143 abut theabutment members 147. Similarly, referring toFIG. 9 , theupper section 105 has been rotated slightly, however theupper section 105 is still not at the preset orientation, and themale engagement members 143 are not aligned with thefemale engagement members 145. Accordingly, thetubular support 112 may still not be inserted into thebackbone 114. Referring toFIGS. 10 and 11 , theupper section 105 has been further rotated, so that theupper section 105 is at the present orientation, and themale engagement members 143 are aligned with thefemale engagement members 145. Accordingly, thetubular support member 112 may be inserted into thebackbone 114 while themale engagement members 143 are inserted into thefemale engagement members 145, and theupper section 105 may be mounted to thefloor cleaning head 106. - Preferably, the
alignment member 139 directs theupper section 105 into the preset orientation as theupper section 105 is mounted on thefloor cleaning head 106. For example, referring back toFIG. 8 , theabutment members 147 may be angled towards thefemale engagement members 145, so that whenmale engagement members 143 contact theabutment members 147, the abutment members act as a camming surface, and guide theengagement members 143 towards thefemale engagement members 145. - In alternate embodiments, the alignment member may be of another suitable configuration. For example, the
male engagement members 143 may be provided on thebackbone 114, andfemale engagement members 145 may be provided on thetubular support member 112. Further the alignment member may be provided on theupper section 105, for example on thecleaning unit 110. - In alternate embodiments, rather that the entire
upper section 105 being removably mountable to thefloor cleaning head 106, only thecleaning unit 110 by itself, or thecleaning unit 110 with some components of theupper section 105 may be removably mountable to thefloor cleaning head 105. In such embodiments, the cleaning unit may still be removably mounted to thesurface cleaning apparatus 100 in a preset orientation. - In the embodiment shown, the
cleaning unit 110 is indirectly mounted to thetubular support member 112, by thebackbone 114. In alternate embodiments, thecleaning unit 110 may be directly mounted to thetubular support member 112. In an alternate embodiment, the alignment member may comprise one or more guide members, e.g., extension arms, provided on the cleaning unit that interact with the upper section when the cleaning unit is mounted on the upper section. - 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.
