Definitions

  • the present disclosure relates to devices and methods for cleaning a food waste disposer.
  • Food waste disposers commonly have a grind chamber which receives multiple types of waste products. Following repeated use, some portions of the waste products may not flush through the disposer after each operation. This can lead over time to waste build-up which can create an odor problem from the remnants of the waste products remaining in the disposer. Cleaning systems have therefore been developed to clean food waste disposers.
  • Known cleaning systems have several drawbacks. Some systems use food materials themselves, such as citrus rinds, bones, or ice cubes to clean the waste disposer. Food products used for this purpose also generally leave behind portions of the food products themselves or are ineffective at cleaning the food waste disposer. Products such as detergent packets have been developed which are introduced into the disposer while the disposer is operating. Citrus rinds and detergent packets can mask the odor of the waste build-up, but because they may not effectively clean the disposer do not eliminate odors. Products such as brushes have therefore been developed which rely on manual scrubbing when the disposer is not operating and commonly provide a handle which reaches outside of the disposer for grasping. Brushes can also miss portions of the waste products due to the inability to reach every portion of the disposer, including the discharge passages from the grind chamber.
  • a low mass and inertia, spherical-shaped brush pod includes a plurality of points or brush elements attached to a central hub.
  • the central hub is created from a material which can slowly be ground up by the disposer over time without damaging the grind elements.
  • the brush pod can be left in the food waste disposer while grinding, or can be removed after cleaning.
  • an elastomeric material is used for the bristles or brush elements.
  • the elastomeric material is preselected to promote chemical resistance, and to minimize weight and therefore reduce mass and inertia of the brush pod.
  • An elastomeric material can also be used for the central hub.
  • a non-geometrically shaped scrub device having a central core and multiple flexible strands of a polymeric material is placed into a food waste disposer where the low mass and low inertia of the scrub device permits a random spinning motion to promote frictional cleaning by the flexible strands.
  • FIG. 1 is a front perspective view of a scrub device of the present disclosure
  • FIG. 2 is a front perspective view another embodiment of a scrub device of the present disclosure
  • FIG. 3 is a partial cross sectional front perspective view of another embodiment of a scrub device of the present disclosure.
  • FIG. 4 is a front perspective view another embodiment of a scrub device having tubular shaped core members
  • FIG. 5 is a front perspective view another embodiment of a pyramidal-shaped scrub device of the present disclosure.
  • FIG. 6 is a front perspective view another embodiment of a non-geometrically-shaped scrub device of the present disclosure.
  • FIG. 7 is a front elevational view of a scrub device holding member
  • FIG. 8 is a front elevational view of a scrub device extraction tool
  • FIG. 9 is a partial cross sectional, front elevational view of a scrub device extraction tool
  • FIG. 10 is a partial cross sectional, front elevational view of another embodiment of a scrub device extraction tool.
  • FIG. 11 is a cross sectional front elevational view of a food waste disposer having a scrub device of the present disclosure shown therein.
  • a scrub device 10 includes a central core 12 having a plurality of bundles 14 extending outwardly from central core 12 .
  • Each of the bundles 14 includes a plurality of flexible strands 16 which can be of equal or different lengths with respect to each other.
  • Central core 12 can be substantially circular in shape as shown or can have any geometric shape.
  • a material for central core 12 can be a polymeric material which is adapted to be received in a food waste disposer (shown and described in reference to FIG. 11 ).
  • Each of the flexible strands 16 are also made from a polymeric material and are flexible to allow the individual flexible strands 16 to individually flex and contact the inner surfaces of the food waste disposer.
  • the food waste disposer is turned on with the scrub device 10 in the disposer to clean the disposer.
  • a scrub device 18 is modified from the scrub device 10 of FIG. 1 to eliminate the bundles 14 and to include a plurality of random flexible strands 22 , a portion of which are centrally grouped or wound to form a central core 20 .
  • Central core 20 is not an independent entity with respect to the flexible strands 22 , having flexible strands 22 extending outwardly therefrom, but is formed of a portion of each of the flexible strands 22 .
  • Central core 20 of scrub device 18 therefore does not have a standard geometric form and can vary in both size and geometry based on a quantity of random flexible strands 22 which are grouped together to form central core 20 .
  • a scrub device 24 has a body 26 including each of a first and second body portion 28 , 30 which are homogenously joined, bonded together such as by thermal bonding, adhesively joined, or otherwise formed as a fixed unit to define body 26 .
  • the first and second body portions 28 , 30 define an interior cavity 32 which can be adapted to receive a liquid or powder material such as a cleaning solution, a fragrance solution, or the like.
  • Interior cavity 32 is accessible for fill and subsequent discharge of the material via an aperture 34 .
  • Body 26 also includes a plurality of faces 36 each having a bundle 38 similar to bundles 14 extending outwardly from the faces.
  • Exemplary ones of bundle 38 are oriented at an angle ⁇ with respect to a longitudinal axis 39 of body 26 .
  • Proximate ones of the bundles 38 identified for example as bundles 38 , 38 ′ can be oriented with respect to each other by a bundle-to-bundle included angle ⁇ .
  • Angles ⁇ and ⁇ can vary at the manufacturers discretion to provide for different quantities of bundles 38 , to promote random rotation of scrub device 24 , or to provide improved access to aperture 34 .
  • a scrub device 40 includes a grouping of multiple tubular shaped barrels 42 which can be oriented at substantially right angles to each other.
  • a bundle 44 extends from a free end of each of the tubular barrels 42 , including from each of the opposed ends of the tubular barrels 42 .
  • the plurality of tubular barrels 42 are homogenously or fixedly connected to one another and can be commonly created during a molding process.
  • a plurality of flexible strands 45 similar to flexible strands 16 are provided with each of the bundles 44 .
  • the core 20 (not visible in this view) of the flexible strands 45 can be centrally located at an interior end of the tubular shaped barrels 42 , or the core 20 can be eliminated and each bundle 44 be independently created in each tubular shaped barrel 42 .
  • a scrub device 46 includes a plurality of triangular-shaped faces 48 which together define a pyramid-shaped structure or core.
  • a bundle 50 of flexible strands, similar to bundles 44 extends from each of the triangular shaped faces 48 .
  • a scrub device 52 includes a non-uniformly shaped body 54 having a plurality of body faces 56 which are oriented randomly with respect to other ones of the body faces 56 .
  • Each of the body faces 56 provides a bundle 58 extending outwardly therefrom, each similar to bundles 44 .
  • the non-geometric body shape of body 54 is advantageous in providing for a greater random motion of scrub device 52 so that individual ones of the bundles 58 are also randomly oriented to provide for enhanced cleaning motion of the scrub device 52 .
  • Scrub device holding tool 60 includes a handle 62 having a slidable lever 64 disposed thereon.
  • Lever 64 is in turn operable to displace an actuation arm 66 which can grasp one of the scrub devices (for example scrub device 18 shown) between actuation arm 66 and a retention end 68 .
  • Holding tool 60 can be oriented to receive a scrub device by sliding lever 64 in a first lever direction “A” to provide clearance space to receive the scrub device.
  • actuation arm 66 contacts the scrub device to capture the scrub device between the actuation arm 66 and retention end 68 .
  • an extraction tool 70 can be provided for removal of a scrub device of the present disclosure such as scrub device 18 shown.
  • Extraction tool 70 includes a handle 72 having a lever 74 slidable in either of a first lever direction “C” or in an opposite second lever direction “D”.
  • Extraction tool 70 has a claw 76 which includes each of a first and second claw arm 78 , 80 which are deflectable toward or away from each other by motion of lever 74 .
  • displacement of lever 74 in the second lever direction “D” allows first claw arm 78 to deflect away from second claw arm 80 in a release direction “E” while second claw arm 80 displaces in a release direction “F”.
  • Operation of lever 74 in the first lever direction “C” provides an opposite action causing first and second claw arms 78 , 80 to displace toward each other to grasp the scrub device 18 .
  • an extraction tool 82 includes an engagement member 84 which is slidably received within a chamber 86 of a receiving member 88 .
  • Engagement member 84 includes a first and second engagement arm 90 , 92 .
  • First and second engagement arms 90 , 92 are movable with respect to each other as they are separated by a partial longitudinal slot 94 .
  • First engagement arm 90 includes a first raised surface 96 and second engagement arm 92 includes a second opposed raised surface 98 .
  • First and second raised surfaces 96 , 98 are adapted to be frictionally received within a comparably sized aperture (shown in phantom) created in a body or central core of one of the various scrub devices previously described herein.
  • a first cavity 100 is defined between first and second engagement arms 90 , 92 proximate and between first and second raised surfaces 96 , 98 .
  • a sliding member 102 having an engagement end 104 adapted to be received in first cavity 100 is positioned as shown in FIG. 9 to force first and second engagement arms 90 , 92 apart from each other which temporarily locks or engages engagement member 84 with the scrub device.
  • By pulling sliding member 102 in an extraction/release direction “H” engagement member 84 slides within chamber 86 until a first and second flange 106 , 108 of the first and second engagement arms 90 , 92 respectively contact each of a first and second stop wall 110 , 112 of receiving member 88 .
  • Second cavity 114 is larger than first cavity 100 allowing first and second engagement arms 90 , 92 to displace toward each other about partial longitudinal slot 94 thereby allowing release of engagement member 84 as first and second raised surfaces 96 , 98 elastically spring toward each other to thereafter reduce the frictional engagement of the scrub device.
  • sliding member 102 When temporarily connecting engagement member 84 with the scrub device, an opposite motion of the sliding member 102 is used. For example, sliding member 102 moved in an engagement direction “G” displaces engagement end 104 from second cavity 114 into first cavity 100 thereby forcing first and second raised surfaces 96 , 98 away from each other to provide a frictional engagement with the scrub device.
  • another extraction tool 116 includes an arm 118 having a sliding member 120 slidably disposed therein.
  • Sliding member 120 includes opposed first and second claw arms 122 , 124 .
  • Extraction tool 116 can be used by pulling sliding member 120 to the right as viewed in FIG. 10 which forces first and second claw arms 122 , 124 into contact with arm 118 and thereby forces first and second claw arms 122 , 124 toward each other to grasp the scrub device (not shown).
  • a contact member 126 can also be provided on one or opposed sides of the first and second claw arms 122 , 124 to assist in retaining the scrub device.
  • a food waste disposer 128 includes an upper food conveying section 130 , a lower motor section 131 , and an intermediate grinding section 132 disposed between the food conveying section 130 and the motor section 131 .
  • the food conveying section 130 includes a housing 133 that forms an inlet 134 at its upper end for receiving food waste, water, and a scrub device of the present disclosure in a direction “J”.
  • the housing 133 also includes a second inlet 135 for receiving water and food waste in a direction “K” discharged for example from a dishwashing machine (not shown).
  • Food conveying section 130 conveys food waste and water to the grinding section 132 .
  • the motor section 131 includes a motor 136 , which may illustratively be an induction motor imparting rotational movement to a motor shaft 138 .
  • the grinding section 132 can include a support plate 140 connected for rotation to motor shaft 138 .
  • Support plate 140 can be connected to a grinding or rotating plate 142 .
  • Water and ground food waste which are combined in a slurry are collected below support plate 140 and rotating plate 142 in a waste receiving cavity 144 for discharge in a discharge direction “L” through a discharge port 146 .
  • Grinding section 132 has a grinding cavity 148 disposed above rotating plate 142 to receive the food waste and a volume of water. Food waste and the water volume can be received through inlet 134 , through second inlet 135 , or both. At least one and in several embodiments a plurality of fixed lugs or elements 150 extend upwardly from and co-rotate with rotating plate 142 . Food waste is forced outwardly by centrifugal force toward elements 150 which force the food waste into contact with cutting edges or teeth defined by a plurality of apertures 152 in a stationary shredder ring 154 .
  • the food waste is ground between an outer edge of elements 150 and the cutting edges of apertures 152 and the ground food waste particles with the water in the form of a slurry moves outwardly as viewed in FIG. 11 through apertures 152 and then downwardly into waste receiving cavity 144 .
  • Lugs 156 function to keep the food waste moving outwardly and therefore to reduce accumulation of food waste in a stationary position with respect to rotating plate 142 and out of reach of elements 150 .
  • scrub device 10 is positioned within housing 133 and grinding cavity 148 .
  • the central core 12 of scrub device 10 is sized smaller than inlet 134 to be received through inlet 134 . Insertion can also be aided by deflection of the flexible strands 16 .
  • the flexibility of the plurality of flexible strands 16 allows individual ones of the flexible strands to contact the inner wall of the housing 133 and the inner wall of the stationary shredder ring 154 so that all areas within housing 133 and grinding cavity 148 , including an outward area “Z” can be contacted for cleaning.
  • motor 136 rotates rotating plate 142 to displace scrub device 10 about the housing 133 and the grinding cavity 148 .
  • Portions of the flexible strands 16 or the central core 12 which are fractured or removed by contact with the elements 150 , rotatable lugs 156 , and/or the cutting edges defined by apertures 152 will be displaced through apertures 152 for discharge through receiving cavity 144 and discharge port 146 .
  • the flexible element scrub devices of the present disclosure can be made from a molded or extruded polymeric material for the flexible strands or bundles, and each of the central cores can also be made of a polymeric material to prevent damage to the elements 150 and cutting edges of the apertures 152 .
  • each of the flexible strands ( 16 , 22 , 45 ) are either homogenously connected to a corresponding core, are wound or grouped into a tight configuration defining a core, or the flexible strands are grouped into the bundles, such as bundles 14 which are fixedly or homogenously connected to the core.
  • Scrub and scour devices, and holding or extraction tools for the scrub and scour devices of the present disclosure provide several advantages.
  • the ability to dispose a scrub or scour device into a food waste disposer and leave the device in the disposer allows for a continuing ability to clean the disposer without further operator action.
  • the flexibility of the flexible strands and the geometry of the scrub devices provides for a low mass, low inertia device which can freely rotate during operation of the food waste disposer to promote cleaning. The low mass makes the presence of the scrub device in the food waste disposer nearly unperceivable in terms of noise and vibration.
  • the center core or hub can be made of a material which itself can be slowly ground by the disposer, or which does not grind during operation but can be retained in the disposer without damaging the operating elements, which allows the devices to be left in the disposer.
  • the flexible strands also provide a self-cleaning action to prevent food waste deposits from building up on the flexible strands themselves.
  • Provision of a cavity in various embodiments of the scrub devices can also allow use of an additional cleaning/disinfecting solution which can automatically discharge from the scrub device.
  • the central core also provides a portion which can be grasped for removal or manual cleaning motion of the scrub devices.
  • An interior cavity similar to interior cavity 32 can be provided in most of the scrub devices of the present disclosure, and can be provided by inclusion of a hollow member in the wound core 20 of scrub device 18 .
