Background of the Invention Field of the Invention 10 The invention relates to suction cleaners. In one of its aspects, the invention relates to a suction cleaner having cyclonic dirt separation. In another of its aspects, the invention relates to a cyclone separator with an improved exhaust grill. In another of its aspects, the 15 invention relates to a vacuum cleaner with a moveable pet hair removal device that is selectively retained in contact with a surface to be cleaned. In still another of its aspects, the invention relates to a dirt cup latching mechanism. 20 Description of the Related Art Many conventional cyclone separators use frusto conical shape separators or high-speed rotational motion of the air/dirt to separate the dirt by centrifugal force. Typically, working air enters and exits at an upper 25 portion of the cyclone separator while the bottom portion of the cyclone separator is used to collect debris. In an effort to reduce weight, the motor/fan assembly that creates the working air flow is typically placed at the bottom of the handle, below the cyclone separator. 30 BISSELL Homecare, Inc. presently manufactures and 46361271 (GHMatters) P80454.AU - 3 sells in the United States an upright vacuum cleaner that has a cyclone separator and a dirt cup. A horizontal plate separates the cyclone separator from the dirt cup.

The separator plate 88 further comprises a lip 98 and a gasket-receiving member 99. The lip 98 20 comprises a thin wall positioned slightly below and vertically aligned with the central opening of the disc like member 89. The lip 98 can have a substantially circular shape sized similarly to the central opening but having a slightly smaller area than the central opening 25 such that debris and air can flow through the central opening and around the lip 98. The gasket-receiving member 99 is spaced from and surrounds a circumference of the lip 98 and is configured to receive a conventional gasket 100. 30 The cyclone separator 90 is formed such that the upstream separator 84 is coaxially aligned with the downstream separator 86. The cylindrical member 85 of the upstream separator 84 sits atop the downstream flange 96 such that the majority of the bottom opening of the 4636127_1 (GHMatters) P80454.AU - 12 cylindrical member 85 is in fluid communication with the top opening of the frusto-conical member 87. The separator plate 88 is aligned coaxially with the upstream separator 84 and downstream separator 86 such that a first 5 stage debris outlet 102 is formed by the space existing between the circumference of the disc-like member 89 of the separator plate 88 and the cyclone housing 70. The central opening of the disc-like member 89 is also in fluid communication with the bottom opening of the frusto 10 conical member 87 such that the lip 98, gasket-receiving member 99, and gasket 100 together form a second stage debris outlet 104 enabling the passage therethrough of debris and air from the downstream separator 84 via the bottom opening of the frusto-conical member 87. The 15 debris outlet 104 also functions as a vortex stabilizer. The cyclone module assembly 26 further comprises a perforated grill 110. The perforated grill 110 comprises an inner grill cylinder 112, an outer grill cylinder 114, and an upper wall 116 integrally formed with and 20 connecting the top edges of the grill cylinders 112, 114. The inner and outer grill cylinders 112, 114 are concentric and have open bottoms. The outer grill cylinder 114 comprises a plurality of apertures 120 enabling the passage of air an debris therethrough. The 25 apertures 120 are formed at an acute angle relative to the direction of flow of working air at an outer surface of the outer grill cylinder 114 during operation of the vacuum. The apertures 120 can be formed by injection molding using a tool with a plurality of slides and/or 30 lifters having varying die-draw angles with respect to the vertical axes of the part. Each slide and/or lifter comprises a plurality of pins, that, when pulled during the ejection process, form the apertures 120 at varying angles with respect to the outer grill cylinder 114. The 35 angular relationship between the longitudinal axis of the apertures 120 and the outer grill cylinder 114 preferably 4636127_1 (GHMatters) P80454.AU - 13 ranges from 10 degrees to 60 degrees. When assembled, the upper wall 116 sits atop the upstream flange 92, and the outer grill cylinder 112 is configured and sized for placement around the upstream 5 separator 84 such that the bottom edge of the outer grill cylinder 112 sits atop the downstream flange 96. The inner grill cylinder 114 is configured and size for placement within the upstream separator 84 such that a bottom opening of the inner grill cylinder 114 is in fluid 10 communication with the top opening of the downstream separator 86. The dirt cup assembly 60 is positioned adjacent the cyclone separation housing 58 and is selectively sealingly mated to the cyclone housing 70 via a sealing lip 150 15 formed around the bottom edge of the cyclone housing 70 and a sealing ring 152. The sealing lip 150 is configured to receive the sealing ring 152 as well as an upper edge 154 of a dirt cup housing 160. The dirt cup housing 160 comprises an inner collection cylinder 162 and an outer 20 collection cylinder 164. The collection cylinders 162, 164 are concentric and substantially hollow. Both collection cylinders 162, 164 are open at their top ends but closed at their bottom ends. The inner collection cylinder 162 has a radius slightly smaller than that of 25 the gasket 100 and also smaller than the outer collection cylinder 164. The dirt cup housing 160 can include any number of additional features within one or both of the collection cylinders 162, 164. When the cyclone module assembly 26 is assembled with 30 the dirt cup assembly 60, a first stage collection area 166 is formed by the space between the outer circumference of the inner collection cylinder 162 and the dirt cup housing 160. A second stage collection area 168, which is sealed off from the first stage collection area 166, is 4636127_1 (GHMatters) P80454.AU - 14 formed within the inner collection cylinder 162. The first stage collection area 166 is in fluid communication with the first stage cyclone 64, and debris can fall into the first stage collection area 166 from the first stage 5 cyclone 64 via the first stage debris outlet 102. The separation plate 88 serves to reduce re-entrainment of debris collected in the first stage collection area 166 into the first stage cyclone 64. The second stage collection area 168 is in fluid communication with the 10 second stage cyclone 62 via the second stage debris outlet 104 to receive debris therethrough. As indicated by the arrows shown in FIG. 3, in operation, the fan/motor assembly is positioned downstream of the second stage cyclone outlet 68. The fan/motor 15 assembly draws air from the first stage cyclone inlet 66 into the cyclone housing 70, causing the air to swirl around the inner wall of the cyclone housing 70 and the downstream separator 86 to form the first cyclone 64. The separation of larger debris occurs in the first cyclone 64 20 with the larger debris falling into the first stage collection area 166 of the dirt cup assembly 60 via the first stage debris outlet 102. Referring also to FIG. 4, the air then travels passes through the perforated grill 110 and enters the cyclone 25 separator 90 via the second stage inlets 94 of the upstream separator 84. The apertures 120 in the perforated grill 110 are formed at an acute angle relative to the working air flow, shown by the arrows labeled A, at the outer surface of the outer grill cylinder 114. In 30 order for the air to pass through the apertures 120 in the perforated grill 110, the working air flow must change direction and reverse back as shown by the arrows labeled B. The change in the direction of working air flow propels debris out of the working air flow, which 35 minimizes the debris passing through the apertures 120 and 4636127_1 (GHMatters) P80454.AU - 15 significantly reduces potential clogging. Once through the perforated grill 110, the working air flows through the second stage inlets 94. The second stage inlets 94 direct the air tangentially and downwardly 5 along an inside surface of the downstream separator 86. The airflow turns near the second stage debris outlet 104 and proceeds directly upward to the second stage outlet 68. The dirt removed by the frusto-conical downstream separator 86 falls into the second stage collection area 10 168. The dirt cup assembly 60 can be detached from the cyclone housing 70 to provide a clear, unobstructed path for the debris captured in both the first stage collection area 166 and the second stage collection area 168 to be 15 removed. Removal can be accomplished by inverting the dirt cup assembly 60. Referring to FIGS. 1, 5 and 7, a pet hair removal device 300 is attached to a forward portion of the foot assembly 14. A pair of opposed hinge caps 302 are fixedly 20 attached to an outer surface of the brush chamber 32. A pair of opposed swing arms 304 rotate within each hinge cap 302. A pair of torsion springs 301 (FIG. 7) are positioned between the hinge caps 302 and the swing arms 304 to bias the pet hair removal device 300 in an upward 25 position above the brush chamber 32 and away from the surface to be cleaned. Each of the torsion springs 301 can be received in a recess 303A in each swing arm 304. The recess 303A is configured to receive a coil 305A of the spring 301. A hook end 305B of the torsions spring 30 301 is retained by a flange 303B on the swing arm 304,. Each of the hinge caps 302 includes a spool 311 that mounts the spring coil 305A and a securing recess 309 for receiving a second end 305C of each of the torsion springs 301. The spool 311 and spring 301 are received in the 4636127_1 (GHMatters) P80454AU - 16 recess 303A. A pet brush cover 306 is fixed to an end of the swing arms 304 opposite the hinge caps 302. A pet hair remover 308 is attached to a lower portion of the pet brush cover 5 306 and comprises one of a number of commonly known hair removal materials. A pet brush bumper 310 comprising a relatively soft and/or resilient material can be affixed to a forward surface of the pet brush cover 306 to prevent damage to furnishings as is commonly known in the vacuum 10 cleaner art. A more detailed description of a suitable pet hair removal device is found in U.S. Patent Application Publication No. 2007/0143954 to Graham et al., which is incorporated herein by reference in its entirety. 15 As shown in FIGS. 5-6D, a latch mechanism 400 selectively secures the pet hair removal device 300 in an in-use position. The latch mechanism 400 comprises a latch portion 402 attached to or formed by the foot assembly 14 upper cover 30 and a catch portion 404 20 attached to or formed with the pet hair removal device 300. The latch portion 402 further comprises a latch button 406 that slides vertically within a channel that is formed in a corresponding latch support 408 that is formed by or attached to the upper cover 30. A latch plate 409 25 is mounted to the inside of the channel formed by the latch support 408 and has a catching surface 418 and a chamfered surface 420 at a lower portion thereof. An actuation surface 410 is formed on an upper surface of the latch button 406. The latch portion 402 is mounted to the 30 latch support 408 through a pair of resilient fingers 422 that are slidably received in a slot 415 at a bottom of the latch support 408 as seen in FIG. 6D. The resilient fingers 422 have outwardly directed barbs on an outer end thereof for retaining the resilient fingers 422 in the 35 slot 415 after the fingers have been mounted in the slot. 46361271 (GHMatters) P80454.AU - 17 The resilient fingers flex inwardly as the fingers are pushed into the slot 415 as the sides of the slot push against the barbs. The latch portion 402 further comprises a plurality of resilient latch fingers 424 that 5 are positioned between the resilient fingers 422 and slide within the slot 415. Each of the latch fingers 424 has a disengaging portion 412 is formed on an opposite, lower surface. The disengaging surface 412 is preferably chamfered or angled relative to a vertical axis. 10 A pair of biasing members 405 in the form of resilient spring arms are integrally formed on a rear support of the latch portion 402 below the latch button 406. The biasing members 405 are cantilevered from the support and extend laterally outwardly and upwardly to 15 rest on two support posts 407 that are formed on the latch support 408. The support posts 407 are spaced apart and extend upwardly from opposite sides of the latch support 408. When the latch portion 402 is assembled to the latch support 408, the biasing members 405 each press against a 20 corresponding support post 407, which forces the latch portion 402 towards an uppermost position relative to the latch support 408. At the same time, the lower portion of the latch portion 402, including the disengaging surface 412, extends downward through an slot 415 at a bottom of 25 the latch support 408. The catch portion 404 is made of a resilient material and is fixed to the pet hair removal device 300 at one end by commonly know fastening mechanisms 413, such as screws, rivets, adhesives, ultrasonic welding, or the like. An 30 end of the catch portion 404 opposite the fixed end comprises a releasing surface 414 that is chamfered or angled to mate with the disengaging portion 412 chamfered surface. A catch surface 416 is formed contiguous with the releasing surface 414. The latch support 408 further 35 comprises a catching surface 418 and a chamfered surface 4636127_1 (GHMatters) P80454.AU - 18 420 that corresponds to the releasing surface 414 of the catch portion 404. In operation, the latch portion 402 is biased in the upward direction by the interaction between the biasing 5 members 405 and the support posts 407. There is no force present between the disengaging portion 412 of the latch mechanism 400 and the releasing surface 414 of the catch portion 404. The pet hair removal device 300 maintains its position due to the interference of the catching 10 surface 418 with the catch surface 416. This interference is created by the upward bias of the resilient catch portion 404. To release the pet hair removal device 300, downward pressure is applied to the actuation surface 410, forcing 15 the latch portion 402 down over the support posts 407 by overcoming the force provided by the biasing members 405 and moving the disengaging portion 412 into contact with the releasing surface 414. As the latch portion 402 moves further, the catch surface 416 deflects downwardly and 20 moves below the chamfered surface 420 allowing the catch surface 416 to clear the catching surface 418. The torsion springs in the hinge caps 302 bias the pet hair removal device 300 to a position above the foot 14 and away from the surface to be cleaned. 25 To place the pet hair removal device 300 back into the in-use position, the user grasps the pet brush cover 306 and rotates the device about the hinge caps 302 until the releasing surface 414 contacts the chamfered surface 420. The catch portion 404 deflects in a downward 30 direction, and the releasing surface 414 slides past the chamfered surface 420. The catch portion 404 returns to is normal or straight position, and the catch surface 416 interfaces with the catching surface 418 to lock the pet hair removal device 300 into the in-use position. 46361271 (GHMatters) P80454.AU - 19 Referring to FIGS 1 and 8, the vacuum cleaner 10 further includes a dirt cup latch assembly 500 for use in mounting the dirt cup assembly 60 in the recess 24 and to the cyclone module assembly 26. In the illustrated 5 embodiment, the cyclone module assembly 26 is mounted to the handle 12. However, it is possible in other embodiments that the cyclone module assembly 26 is removably mounted within the recess 24 and can be attached to the dirt cup assembly 60, which can in turn be used to 10 mount both itself and the attached cyclone module assembly 26 to the vacuum cleaner 10. The dirt cup latch assembly 500 comprises a latch assembly 502 and a support platform 504. The latch assembly 502 comprises a pivot bearing 506 in spaced relation to a cam surface 508. The pivot 15 bearing 506 is secured to a pivot support 509 that is anchored to a floor of the recess 24. A lever 510 extends away from the pivot bearing 506 toward the forward portion of the handle 12 and is accessible to the user via a grip 512. The cam surface 508 contacts a lower surface 516 of 20 the support platform 504 while a lower portion of the dirt cup housing 160 removably contacts an upper surface 518 of the support platform 514. In operation, the lever 510 is placed in its lowermost position (shown in dotted lines), moving the 25 support platform 504 down and thus creating the maximum space between the upper surface 518 of the support platform 504 and the lip 150 on the cyclone separation housing 58. The dirt cup assembly 60 is placed on the upper surface 518 of the support platform 504 within the 30 recess 24. The user lifts the lever 510 via the grip 512, which rotates the latch assembly 502 about the pivot bearing 506. This action moves the cam surface 508 relative to the lower surface 516 of the support platform 504. The extended length of the cam surface 508 moves the 35 support platform 504 upwardly (shown in solid lines) and, with it, the dirt cup assembly 60, until the upper edge 4636127_1 (GHMatters) P80454,AU - 20 154 of the dirt cup housing 150 sealingly engages with the lip 150 on the cyclone separation housing 58. An over center design is implemented with the pivot bearing 506 relative to the cam surface 508 so that the latch assembly 5 502 remains in the upward or latched position. Referring to FIGS 1 and 91, an alternate dirt cup assembly latching mechanism comprises a biasing member 520 in place of the latch assembly 502 previously described. In this embodiment, the biasing member 520 is positioned 10 between the recess 24 and the lower surface 516 of the support platform 504. In operation, the dirt cup assembly 60 is placed on the upper surface 518 of the support platform 504 and the user pushes down on the dirt cup housing 160, compressing the biasing member 520 until the 15 upper surface of the dirt cup housing 160 clears the lip 150 in the cyclone module 26. Once the upper edge 154 of the dirt cup housing 160 is positioned within the lip 150, the user releases the dirt cup housing 160, the biasing member 520 expands vertically, and the dirt cup housing 20 160 seals at the lip 150. While the invention has been specifically described in connection with certain specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation. It is anticipated that the cyclone 25 separators described herein can be utilized for both dry and wet separation. Furthermore, the features described can be applied to any cyclone separation device utilizing a single cyclone, or two or more cyclones arranged in any combination of series or parallel airflows. In addition, 30 whereas the invention has been described with respect to an upright vacuum cleaner, the invention can also be used with other forms of vacuum cleaners, such as canister or central vacuum cleaners.
