FIG. 1 illustrates avacuum cleaner 10 according to one embodiment. Although the illustratedvacuum cleaner 10 is an upright style vacuum cleaner, in other embodiments, other types of vacuum cleaners can be used (e.g., handheld, canister, etc.). Thevacuum cleaner 10 includes asuction inlet 12, asuction source 14, and aseparator assembly 16. Thesuction source 14 is operable to generate an airflow through thesuction inlet 12 to draw debris with the airflow through thesuction inlet 12. Theseparator assembly 16 is downstream from thesuction inlet 12 and separates the debris from the airflow. - Referring to
FIGS. 2-4 , theseparator assembly 16 includes acontainer 18, aclean air outlet 20, and ashroud 22. Thecontainer 18 includes anupper end 24 and alower end 26. Thecontainer 18 defines acyclonic separator 28 about aseparator axis 30. Theseparator axis 30 extends centrally through thecontainer 18 and centrally through theends container 18 further includes adirty air inlet 32 that is positioned to receive the airflow and debris. Thedirty air inlet 32 is configured to rotate the airflow and debris around theseparator axis 30 around theshroud 22 within thecontainer 18 in a first direction ofarrow 34 inFIG. 4 , viewed from above the separator assembly for convenience. Theclean air outlet 20 discharges the airflow from theseparator assembly 16. The illustratedclean air outlet 20 extends through and from theupper end 24 of thecontainer 18. In various embodiments, the cyclonic separator may be a first stage separator or a second or subsequent stage separator. - The
shroud 22 forms anairflow passageway 44 between thedirty air inlet 32 and theclean air outlet 20. Theshroud 22 is located within thecontainer 18 between theupper end 24 and thelower end 26 of thecontainer 18. Theshroud 22 includes anupper end 36 having an upper opening 38 (FIG. 7 ) and theshroud 22 includes alower end 40 having alower opening 42. Theupper end 36 of theshroud 22 is releasably connected to theupper end 24 of thecontainer 18. - The
shroud 22 includes theairflow passageway 44. Theairflow passageway 44 is formed by a plurality ofvanes 46 definingopenings 48 betweenadjacent vanes 46. Theopenings 48 and thevanes 46 are positioned to direct the airflow (and any debris not yet separated from the airflow) from the outside of the shroud to the inside of the shroud in the direction ofarrows 50 inFIG. 4 , viewed from above the separator assembly for convenience. Generally, theopenings 48 open toward or face in a direction that is opposed to the flow direction (arrow 34) outside of the shroud in thecyclonic separator 28. The flow direction (arrows 50) through theopenings 48 between thevanes 46 is in a direction partially opposed to the flow direction (arrow 34) in thecyclonic separator 28. When the airflow travels from thecyclonic separator 28 and through theshroud 22, the airflow is redirected in somewhat of an opposite direction to form a rotational flow inside the shroud opposite direction of the flow direction in thecyclonic separator 28. This redirection of airflow further helps to separate the debris from the airflow and minimizes the debris that travels through theopenings 48 between thevanes 46. Referring toFIG. 4 ,sidewalls 71 ofadjacent vanes 46 converge to define openings between vanes having a decreasing area in the direction of airflow into the shroud. This causes air to increase in speed as the air travels through thevanes 46 to further encourage the rotational flow inside the shroud. - A shown in
FIG. 7 , a mesh screen 54 is positioned on theshroud 22, outside thevanes 46. The screen 54 extends around theseparator axis 30 and covers theopenings 48 between thevanes 46 so that the airflow must travel through the mesh screen 54 before traveling through theopenings 48 between thevanes 46. The mesh screen 54 further inhibits debris from traveling with the airflow through theshroud 22. Additionally, the mesh screen introduces radial flow from the rotational flow in thecyclonic separator 28 to the entrance to theopenings 48 in the shroud. There is a gap 70 between the mesh screen 54 andvanes 46. In one embodiment, the gap 70 is 5 millimeters (mm). In other embodiments, the gap is between 2 and 7 mm. In other embodiments the gap is greater than zero (i.e., the mesh screen does not press directly against the vanes 46). The mesh screen may be a perforated metal mesh with punched or etched pores. Alternatively, the mesh screen may be a wire or fiber mesh. The surface area of the openings in the mesh screen is in a range from 20% to 50% of the total surface area of the mesh screen surface. In one embodiment, the mesh screen 54 has pores each having a pore size in a range from 450 micrometers to 100 micrometers. In other embodiments, the pore size is in a range from 400 micrometers to 150 micrometers. In another embodiment, the pore size is in a range from 400 micrometers to 220 micrometers. In yet other embodiments, the pore size is in a range from 350 micrometers to 200 micrometers. In one alternative, the pore size is in a range from 300 micrometers to 220 micrometers. - A
filter 58 is located within theshroud 22. In the illustrated embodiment, thefilter 58 extends from thelower end 40 of theshroud 22 and through theupper opening 38 of theshroud 22. Thefilter 58 extends around theseparator axis 30 and thefilter 58 is positioned in the airflow path between thevanes 46 and thecleaner air outlet 20. Thefilter 58 further separates debris from the airflow. Thefilter 58 includes an openupper end 60 and a closedlower end 62. The illustratedfilter 58 is generally cylindrical and includes an opencentral portion 63 that is in fluid communication with theclean air outlet 22. The closedlower end 62 of thefilter 58 contacts theshroud 22 adjacent thelower end 40 of theshroud 22. The contact between thefilter 58 and theshroud 22 closes thelower opening 42 of theshroud 22 to define a filter dirt collection chamber 64 within theshroud 22 between thevanes 46 and thefilter 58. Thefilter 58 can be made from any suitable filter media, including pleated media, open cell foam media, natural fiber media, synthetic media, or any combination thereof. - The
separator assembly 16 further includes alid 66 and adebris collection chamber 68 below theshroud 22. Thedebris collection chamber 68 is defined by thecontainer 18 at thelower end 26 of thecontainer 18. Thefilter 58 is removably coupled to thelid 66 and thelid 66 and thefilter 58 are together removably coupled to thecontainer 18 adjacent theupper end 24 of thecontainer 18. Therefore, thefilter 58 is removable through theupper opening 38 of theshroud 22 when thelid 66 is uncoupled from thecontainer 18 leaving the shroud in theupper end 24 of thecontainer 18. When the filter is removed from theshroud 22, the closed lower end of the filter is removed from the lower opening in the shroud enabling dirt and debris to empty from the filter dirt collection chamber 64 into thedebris collection chamber 68 below theshroud 22. Thefilter 58 can then be uncoupled from thelid 66 to clean or replace thefilter 58. In an alternative embodiment, theshroud 22 is coupled to thelid 66 so that theshroud 22 is removable with thelid 66 and thefilter 58 from thecontainer 18. In yet another embodiment, the shroud and filter may remain with thecontainer 18 when thelid 66 is removed from thecontainer 18. In such an embodiment, debris in the chamber 64 falls through thelower opening 42 of the shroud and into thedebris collection chamber 68 when the filter is removed from the shroud. - In an alternative embodiment, the vacuum cleaner includes a separator assembly downstream from the suction inlet and a debris collection chamber, where the separator assembly includes a container that defines a cyclonic separator about a separator axis, with a dirty air inlet positioned to receive the airflow and debris so that the airflow and debris rotates around the separator axis in a first direction within the container. The separator includes a clean air outlet that discharges the airflow from the separator assembly. The separator assembly further includes a shroud located in the container having apertures forming an airflow passageway between the dirty air inlet and the clean air outlet, the shroud having an upper end and a lower end having a lower opening. A filter is positioned at least partially within the shroud extending around the separator axis positioned in an airflow path between the shroud and the clean air outlet, where a closed end of the filter contacts the shroud adjacent the lower end closing the lower opening defining a filter dirt collection chamber within the shroud between the plurality of vanes and the filter.
- The apertures in the shroud in this embodiment may be longitudinal slots, openings between vanes, holes of any shape, or other apertures.
- In operation, the
vacuum cleaner 10 is used to remove debris from a surface (e.g., carpet, hard flooring, upholstery, etc.). Thesuction source 14 generates an airflow that draws the debris and airflow through thesuction inlet 12. The airflow and debris travels into thecyclonic separator 28 through thedirty air inlet 32. The airflow and debris rotate around theseparator axis 30 in the direction ofarrow 34 inFIG. 4 . Debris is separated from the airflow and the debris falls down into thedebris collection chamber 68. The airflow travels through the mesh screen 54 that further separates debris from the airflow. After traveling through the mesh screen 54, the airflow travels in the direction ofarrows 50 through theopenings 48 between thevanes 46. The redirection of the airflow by the vanes 46 (discussed above) may further separate debris from the airflow. Separated debris can fall into the filter dirt collection chamber 64. The airflow then passes through thefilter 58 to further remove relatively fine debris from the airflow. The debris separated by thefilter 58 may collect on the filter or fall into the filter dirt collection chamber 64. The airflow travels through thefilter 58 and into the opencentral portion 63 of thefilter 58. From the opencentral portion 63 of thefilter 58, the airflow passes through theclean air outlet 20, which can include an aperture in thelid 66, before being exhausted from thevacuum cleaner 10. - The user can empty the filter dirt collection chamber 64 by removing the
lid 66 from thecontainer 18. In the illustrated embodiment, theshroud 22 and filter dirt collection chamber 64 are removed from thecontainer 18 with thelid 66. Therefore, the user uncouples theshroud 22 from thelid 66 to empty the chamber 64. Thedebris collection chamber 68 can be emptied through theupper end 24 of thecontainer 18. In other embodiments, thecontainer 18 includes a door or a lid adjacent thelower end 26 of thecontainer 18 to empty thechamber 68. - Various features and advantages of the invention are set forth in the following claims.
