The bag compartment includes a wall and a plurality of v-shaped ribs projecting from the wall into the bag compartment.
Description
- This document relates to the floor care appliance field and, more particularly, to a bag compartment for a vacuum cleaner.
- Upright and canister vacuum cleaners that utilize a filter bag to collect dirt and debris are well known in the art. Such vacuum cleaners include a suction generator that draws an air stream entrained with dirt and debris through the filter bag. The filter bag includes a porous wall that captures the dirt and debris but allows the passage of the air stream. The relatively clean air stream then passes over the suction generator to provide cooling to the suction generator motor before being exhausted into the environment.
- In order to maintain optimum operating efficiency, the filter bag must be maintained away from the walls of the bag compartment so as to allow the free passage of the air stream through the porous filter bag material. U.S. Pat. No. 7,752,707 to Mayes, et al and assigned to the assignee of the present invention illustrates a vacuum cleaner with a bag compartment and cooperating bag cage specifically adapted to achieve this purpose.
- The present vacuum cleaner includes a unique and novel series of ribs on the wall of the bag compartment that allow for enhance air flow through the porous material of the filter bag and then more efficiently direct that air flow to the outlet leading from the bag compartment to the suction generator. This results in improved vacuum cleaner performance.
- A vacuum cleaner is provided having a body including a nozzle assembly, a handle assembly, a bag compartment and a suction generator compartment. A suction generator is held in the suction generator compartment. Further the bag compartment includes a wall and a plurality of v-shaped ribs projecting from the wall into the bag compartment. Each rib of the plurality of v-shaped ribs includes two opposing legs and an apex. Further, each rib includes a groove. The groove is provided at the apex and may be centered on the apex. Each rib is also continuous. Each rib has a height H1 at the groove that is less than the height H2 at a portion of the rib not including the groove. The ratio of the height H1 to the height H2 is typically between about 1:3 and about 1:6.
- The bag compartment also includes an inlet and an inlet end and an outlet and an outlet end. The plurality of v-shaped ribs are spaced along the wall between the inlet end and the outlet end with the apexes pointing toward the outlet end. Further, the grooves in the plurality of v-shaped ribs increase in size from the inlet end to the outlet end. Thus each groove in the series has enhanced capacity for allowing air flow.
- In addition, the vacuum cleaner includes two air flow ribs extending along the wall across the plurality of v-shaped ribs from the inlet end to the outlet end. In one particularly useful embodiment the two air flow ribs diverge from one another as they extend from the inlet end to the outlet end. The apexes of the plurality of the v-shaped ribs are positioned between the two airflow ribs with the grooves centered on the apexes.
- Still further describing the vacuum cleaner, the wall includes an access door and the plurality of v-shaped ribs are provided on the access door. In addition, the wall includes a surface opposite the access door. Longitudinal air guides project from that surface into the bag compartment and extend from the inlet end toward the outlet end. V-shaped rib extensions extend from the plurality of the v-shaped ribs to one of the longitudinal air guides. Further, the inlet projects through the surface opposite the access door and the outlet projects through the end wall. An angled grate is positioned between the surface of the end wall overlying that outlet.
- In the following description there is shown and described several different vacuum cleaner embodiments. As should be realized, the vacuum cleaner is capable of still other different embodiments and its several details are capable of modification in various, obvious aspects. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.

- Reference is now made to
FIGS. 1 a-1 d illustrating anupright vacuum cleaner 10. Thevacuum cleaner 10 has abody 12 that includes anozzle assembly 14, ahandle assembly 16, abag compartment 18 and asuction generator compartment 20. See alsoFIGS. 2 and 3 . In the illustrated embodiment, both thebag compartment 18 andsuction generator compartment 20 are part of thehandle assembly 16. It should be appreciated, however, that in other embodiments either or both of thesecompartments nozzle assembly 14. - The
nozzle assembly 14 includes an agitator cavity 22 that receives a rotary agitator 24. The rotary agitator 24 includes bristle tufts or other resilient projections 26 that function to brush dirt and debris from the underlying nap of a carpet being cleaned. Thehandle assembly 16 is pivotally connected to thenozzle assembly 14 in the manner of upright vacuum cleaners known in the art. Thus, thehandle assembly 16 may be pivoted from the upright storage position illustrated inFIGS. 1 a-1 c into an inclined position whereby an operator may freely move thevacuum cleaner 10 to and fro to clean an underlying floor or carpet. Thehandle assembly 16 includes alower housing 28 that defines thesuction generator compartment 20 and anupper housing 30 that defines thebag compartment 18. Theupper housing 30 includes afront access door 32. - As illustrated in
FIGS. 2 , 3 and 6 a-6 c, thebag compartment 18 includes aninlet 34 at aninlet end 36 of the bag compartment and anoutlet 38 in anoutlet end 40 of the bag compartment. As best illustrated inFIG. 2 , anangled grate 42 is positioned between therear wall surface 44 and theoutlet end wall 40 overlying theoutlet 38. As should be appreciated, thegrate 42 is illustrated inFIGS. 2 and 6 a. However, thegrate 42 is removed inFIGS. 6 b and 6 c so as to better illustrate theoutlet 38. - During vacuum cleaner operation, the
suction generator 46 in thesuction generator compartment 20 generates a negative pressure that draws an air stream through the agitator cavity 22 around the rotary agitator 24. Simultaneously, the agitator 24 is rotated at high speeds so that the bristle tufts 26 beat dirt and debris from the nap of an underlying carpet or rug being cleaned. This dirt and debris is entrained in the air stream and travels from the agitator cavity 22 through aconduit system 48 to theinlet 34 that extends through therear wall 44 of thebag compartment 18. Afilter bag 50 is received over the end of theinlet 34 so that the air stream with entrained dirt and debris is directed into the filter bag. - The
filter bag 50 is made from a filter material that traps dirt and debris while allowing the passage of relatively clean air. Accordingly, dirt and debris is trapped in thefilter bag 50 while clean air passes through thefilter bag 50 and travels through thefilter bag compartment 18 and thegrate 42 to theoutlet 38. Anoptional filter element 52 may be provided behind thegrate 42 and over the outlet 38 (see particularlyFIG. 3 ). The air stream is then directed through theconduit 54 into the suction generator compartment 20 (see particularlyFIGS. 3 and 4 ). The air stream is then drawn into theinlet end 56 of thesuction generator 46. The air stream then passes over the motor of thesuction generator 46 to provide cooling before being exhausted from thesuction generator compartment 20 to the environment through thevent 58. Here it should be noted that thesuction generator 46 is mounted in thesuction generator compartment 20 so as to seal against thepartition 60 that separates theinlet portion 62 of thesuction generator compartment 18 from theoutlet portion 64 of the suction generator compartment. - In order to optimize the operating efficiency of the
vacuum cleaner 10, it should be appreciated that thewall 66 of thebag compartment 18 includes a plurality of chevron or v-shapedribs 68 that project from the wall into the bag compartment (see particularlyFIGS. 5 a-5 c). In the illustrated embodiment, these v-shapedribs 68 are provided on theinner wall surface 66 of theaccess door 32. It should be appreciated, however, that the v-shapedribs 68 could be provided on any inner wall surface of thebag compartment 18 if desired. - As illustrated, each v-shaped
rib 68 includes two opposinglegs 70 and an apex 72. Each apex 72 points toward the outlet end 40 of thebag compartment 18. Further each v-shapedrib 68 includes agroove 74 that is provided at and centered on each apex 72. See alsoFIG. 5 d. Eachrib 68 is continuous and each rib has a height H1 at thegroove 74 that is less than the height H2 at any portion of the rib not including the groove. In one particularly useful embodiment the ratio of the height H1 to the height H2 is between about 1:3 and about 1:6. - As should be appreciated from viewing
FIGS. 3 and 5 a-5 c, the plurality of v-shapedribs 68 are spaced along thewall 66 between theinlet end 36 and the outlet end 40 of thebag compartment 18.Rib extensions 69 extend around thecorners 71 of theaccess door 32 and along thesides 73 thereof (seeFIGS. 5 b and 5 c). As should further be appreciated from carefully reviewingFIGS. 5 a-5 d, thegrooves 74 in the plurality of v-shapedribs 68 increase in size from theinlet end 36 to theoutlet end 40. - As further illustrated in
FIGS. 5 a-5 d, twoair flow ribs 76 extend along thewall 66 across the plurality of v-shapedribs 68 from theinlet end 36 to theoutlet end 40. The twoair flow ribs 76 diverge from one another from theinlet end 36 toward theoutlet end 40. Theapexes 72 andgrooves 74 of the v-shapedribs 68 are positioned between the twoair flow ribs 76 which define anexpress airflow pathway 75 leading to the outlet end 40 of thebag compartment 18. In the illustrated embodiment eachgroove 74 is substantially as wide as the space between the divergingribs 76 that is intersected by therib 68 on which the groove is formed. - During vacuum cleaner operation, the v-shaped
ribs 68 function to maintain an airflow passage orgap 78 between thefilter bag 50, theribs 68 and thewall 66 of theaccess door 32. Accordingly, the air stream may freely flow from the interior of thefilter bag 50 through the wall of the filter bag into theair flow passage 78. The air stream is then directed by the v-shapedribs 68 downwardly toward theapexes 72. Thegrooves 74 at each succeedingapex 72 increase in size so as to accommodate additional air flow which is directed through the grooves toward theoutlet end 40 where the airstream may flow freely through theangled grate 42 into theoutlet 38. - The
wall 44 at the rear of thebag compartment 18 opposite theaccess door 32 includes a series of longitudinal air guides 82 that project from the surface into the bag compartment and extend from theinlet end 36 toward theoutlet end 40.Additional airflow ribs 84 extend around the wall at the sides of thebag compartment 18 from the longitudinal air guides 82 to theremovable access door 32. These extensions further direct the airflow along left and right sides of thefilter bag 50 toward the v-shapedribs 68 so that the air stream may pass through thegrooves 74 along theaccess door 32 and flow smoothly to theoutlet 38. As should be appreciated, air passing through the rear wall of thefilter bag 50 flows cleanly and smoothly in thechannels 86 formed between the longitudinal air guides 82 toward theangled grate 42 and through theoptional filter element 56 into theoutlet 38. - In summary, numerous benefits result from employing the concepts of this
vacuum cleaner 10. Specifically, the v-shapedribs 68 and the cooperatingrib extensions 84 function to maintain anopen airflow passage 78 between thefilter bag 50, theribs 68 and thewall 66 of thebag compartment 18. Theribs 68, theextensions 84, the divergingair flow ribs 76 and the cooperatinggrooves 74 at theapexes 72 of the v-shaped ribs synergistically cooperate to smoothly and efficiently guide the air stream through theairflow passage 78, theangled grate 42, theoptional filter element 52, and theoutlet 38 toward thesuction generator 46. The longitudinal air guides 82 along therear wall 44 of thebag compartment 18 provide longitudinal,continuous channels 86 that function to also enhance airflow through the rear of thefilter bag 50 and thebag compartment 18 toward thesuction generator 46. In this way, thevacuum cleaner 10 provides more efficient and effective cleaning. - The foregoing description of the preferred embodiments of the present vacuum cleaner have been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the vacuum cleaner to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments were chosen and described to provide the best illustration of the principles of the current vacuum cleaner and its practical application to thereby enable one of ordinary skill in the art to utilize the vacuum cleaner in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the current vacuum cleaner as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled. The drawings and preferred embodiments do not and are not intended to limit the ordinary meaning of the claims in their fair and broad interpretation in any way.
