Abstract
A dishwasher for treating dishes according to any automatic cycle of operation may comprise a treating chamber having an access opening, a door selectively closing the access opening, and a dispenser for dispensing a treating chemistry into the treating chamber. The dispenser may comprise a treating chemistry compartment defining a cavity with an open face. The dispenser may further comprise a movable element movable within the cavity between retracted and extended positions. An actuator may move the movable element between the retracted and extended positions. When the treating chemistry is placed within the cavity, the movement of the movable element from the retracted to the extended position may expel the treating chemistry from the cavity through the open face.
Description
- Contemporary automatic dishwashers for use in a home typically include a dispenser for automatically dispensing one or more treating chemistries at an appropriate time during an automatic cycle of operation. One common type of dispenser is a compartment with a lid disposed on the inside of a door closing the treating chamber, where the lid opens to release a liquid or solid detergent into the treating chamber of the dishwasher. However, the spraying system for treating articles within the treating chamber may be blocked, for example by utensils or plates, such that the treating chemistry is not fully expelled or sufficiently dissolved, resulting in poor wash performance. One solution to incomplete expelling is to use a detergent-filled bellows that is actuated by water pressure to force detergent through a delivery passage and into the treating chamber. However, this method may be expensive to implement and may not be amenable to solid treating chemistries.
- Another solution is an ejection wheel and release shutter for ejecting spherical detergent tablets from a cartridge. However, this solution may also be expensive and may not be adaptable to liquid treating chemistries. Still another solution may comprise a dispensing valve located on a bottom side of a detergent reservoir and actuated by a bimetallic spring member that is heated to move a plunger actuating the dispensing valve. Unfortunately, the water spray of the dishwasher may not forcefully reach the bottom side of the reservoir and therefore leave a residue of treating chemistry.
- In one embodiment, a dishwasher for treating dishes according to any automatic cycle of operation may comprise a treating chamber having an access opening, a door selectively closing the access opening, and a dispenser for dispensing a treating chemistry into the treating chamber. The dispenser may comprise a treating chemistry compartment defining a cavity with an open face. The dispenser may further comprise a movable element movable within the cavity between retracted and extended positions. An actuator may move the movable element between the retracted and extended positions. When the treating chemistry is placed within the cavity, the movement of the movable element from the retracted to the extended position may expel the treating chemistry from the cavity through the open face.
- In another aspect, a dispenser for dispensing a treating chemistry into a treating chamber of a dishwasher may comprise a treating chemistry compartment defining a cavity with an open face, a movable element moveable within the cavity between retracted and extended positions, and an actuator moving the moveable element between the retracted and extended positions. When the treating chemistry is placed within the cavity, the movement of the movable element from the retracted to the extended position may expel the treating chemistry from the cavity through the open face.
- In yet another aspect, a method for dispensing a treating chemistry into a treating chamber of a dishwasher from a dispenser cavity having a face open to the treating chamber may comprise moving a moveable element between a retracted position within the cavity to an extended position near the open face. The method may further comprise expelling through the face the treating chemistry within the cavity. The method may further comprise spraying liquid into the treating chamber after the expelling of the treating chemistry such that a portion of the liquid flows over the moveable element.

FIG. 1 is a schematic, side view of adishwasher 10 for treating dishes according any automatic cycle of operation.Dishwasher 10 may include achassis 12 defining a treatingchamber 14 having an access opening 16. While the present invention is described in terms of a conventional dishwashing unit, it could also be implemented in other types of dishwashing units, such as in-sink dishwashers, multi-tub dishwashers, or drawer-type dishwashers. Acontroller 40 may be located within thechassis 12 and may be operably coupled bycontrol lines 44 to a treatingchemistry dispenser 20, apump assembly 52, and a heater 56 for implementing one or more automatic cycles of operation.Dispenser 20 may dispense a treatingchemistry 38 into treatingchamber 14 during a cycle of operation. Auser interface 42 may be provided on thedishwasher 10 and may be coupled withcontroller 40. Theuser interface 42 may include operational controls such as dials, lights, switches, and displays enabling a user to input commands, such as a cycle of operation, to thecontroller 40 and receive information.Access opening 16 may be selectively closable bydoor 18 which may be hingedly mounted to thechassis 12. A further elaboration of thedispenser 20 is provided below. - Continuing with
FIG. 1 ,dish racks 68 may be located within the treatingchamber 14 for receiving dishes to be treated.Racks 68 may be mounted for slidable movement in and out of the treatingchamber 14 for ease of loading and unloading. As used in this description, the term “dish(es)” is intended to be generic to any item, single or plural, that may be treated in thedishwasher 10, including, without limitation; dishes, plates, pots, bowls, pans, glassware, silverware, and other utensils. A spraying system emittingwash liquid 50 may comprise anupper sprayer 62, amid-level sprayer 64, a lowerrotatable spray arm 66, and a sprayingmanifold 60. Acavity 22 and arear wall 26 ofdispenser 20 may be exposed to a spray ofwash liquid 50 whenlid 28 is open.Lid 28 may selectively close theopen face 24 of the treatingchemistry dispenser 20. Ideally,wash liquid 50 fromsprayers chemistry 38 fromcavity 22 and may also cleanrear wall 26 ofdispenser 20. However, without further steps, dishes and portions ofrack 68 may partially obstructwash liquid 50 from fully dissolving and expelling treatingchemistry 38 fromcavity 22, and may preventrear wall 26 from being cleaned of any residues of treatingchemistry 38. - Referring still to
FIG. 1 , a liquid recirculation system may be provided for recirculating liquid from the treatingchamber 14 to the spraying system. Thepump assembly 52 may include both a drain pump (not shown) feedingdrain line 54 and a recirculation pump. A heating system having a heater 56 may be located near thepump assembly 52 forheating wash liquid 50. A filtering system (not shown) may be fluidly coupled with the recirculation flow path for filtering thewash liquid 50. - Various embodiments of

Starting with the two embodiments ofFIGS. 2A-2B and 3A-3B , thedispenser 20 may comprise a slidingmovable element 30 and may include a membranousrear wall 26 attached to aside 31 of a treatingchemistry compartment 23.Compartment 23 may definecavity 22 withopen face 24 andlid 28 may selectively closeopen face 24. Treatingchemistry 38 may be placed withincavity 22 whenlid 28 is open, normally prior to running an automatic cycle of operation (FIG. 5A ).Movable element 30 may move withincavity 22 between a retracted 32 (FIGS. 2A, 3A ) and an extended 34 position (FIGS. 2B, 3B ). Anactuator 36 may movemovable element 30 between the retracted 32 and extended 34 positions, where the extended position may expel treatingchemistry 38 fromcavity 22 throughopen face 24.Actuator 36 and may comprise a wax motor (not shown), but may also be a linear actuator, a spring loaded device, or a magnetic or a thermally actuated mechanism. In an embodiment, the movable element may comprise arear wall 26 of a treatingchemistry compartment 23 and may be oppositeopen face 24.Lid 28 may pivot aroundlid pivot 70, or may pivot from one or more pivot locations ondispenser 20. Alternatively,lid 28 may slidably coveropen face 24 or may engagecompartment 23 by any other means know in the art. Additionally,lid 28 may comprise multiple lid sections (not shown) coveringopen face 24. - Continuing with
FIGS. 2A-2B and 3A-3B , in various embodiments,movable element 30 may also comprise an elastomeric membrane and which may be stretchable between the retracted 32 position withincavity 22 and the extended 34 position near theopen face 24.Movable element 30 may be located behind the elastomeric membrane formingrear wall 26, and may extend 34 the elastomeric membrane from a retracted 32 position withincavity 22 to a position nearopen face 24. InFIGS. 2A-2B , anedge 29 ofelastomeric membrane 26 may attach to aside 31 ofcompartment 23 recessed away fromopen face 24 such that themembrane 26 may be relatively relaxed in the retracted 32 position and may be stretched in the extended 34 position. InFIGS. 3A-3B , anedge 29 ofelastomeric membrane 26 may attach to aside 31 ofcompartment 23 nearopen face 24 such that themembrane 26 may be stretched in the retracted 32 position and may be relatively relaxed in the extended 34 position.Membrane 26 may be co-formed withmovable element 30 or may be adhered tomovable element 30. Anedge 27 ofmovable element 30 may be spaced fromcompartment 23 or may be positioned toslidably contact compartment 23. -
FIGS. 4A-4B refer to a third embodiment similar to the embodiments ofFIGS. 2A-3B , with differences as follows.Movable element 30 may comprise therear wall 26 ofcompartment 23 and may directly extend 34 to expel treatingchemistry 38 without the use of an elastomeric membrane.Movable element 30 may slide withincompartment 23, and anedge 27 of the element may be closely spaced against an inside ofcompartment 23 for moving substantially all of treatingchemistry 38 toward treatingchamber 14. The dishwasher may further comprise anelement scraper 74 onmovable element 30 that scrapes against aside 31 of thecompartment 23 as themovable element 30 moves between the retracted 32 and extended 34 positions. For example, ascraper 74 may extend from anedge 27 ofelement 30 to the inside ofcompartment 23 and may move substantially all of the treatingchemistry 38 withincavity 22 toward the open face during dispensing (FIGS. 4A-4B ), thereby leaving no residue withincavity 22.Scraper 74 may be a rubber seal, or may be fabricated from at least one of plastic, metal, elastomer, or foam.Scraper 74 may be co-formed withmovable element 30 and may be tapered toward the outer edge scraping againstcompartment 23. - In embodiments not shown,
rear wall 26 may extend 34 towardopen face 24 by anactuation 36 of water or air pressure located behindmovable element 30. The water or air pressure may press against an elastomeric membrane attached to aside 31 ofcompartment 23 or may press against a rigidmovable element 30, or against a combination of a rigid movable element and the elastomeric membrane. Advantageously, positioningrear wall 26 nearopen face 24 may better exposedispenser 20 to a spray ofwash liquid 50 present during a portion of a cycle of operation ofdishwasher 10. The cycle may include a spraying ofwash liquid 50 within treatingchamber 14 such that a portion of the liquid flows overelement 30, and may thereby remove residual treatingchemistry 38 fromelement 30.Dishwasher 10 may further comprise a separate sprayer (not shown) emitting a spray ofwash liquid 50 directly ontomovable element 30 in at least the extended 34 position. - Referring now to
FIGS. 5A-5B , in a fourth embodiment,movable element 30 may pivotally mount todispenser 20 and may be actuated 36 to moverear wall 26 from a retracted position 32 near the back of atriangular cavity 22 to an extended position 34 nearopen face 24. In an embodiment,movable element 30 may pivotally mount 72 to aside 31 of treatingchemistry compartment 23. In another embodiment, themovable element 30 may change its shape to expel the treating chemistry. For example,movable element 30 may be an inflatable or expandable element sized to fill upcavity 22 and positionrear wall 26 nearopen face 24 in the extended 34 position.Element 30 may then retract into a deflated or collapsed shape having a lower volume withincavity 30 when in the retracted position. Air or water pressure positioned behindelement 30 may actuate 36 between the retracted 32 and extended 34 positions for the purpose of expelling treatingchemistry 38.Lid 28 may selectively close theopen face 24 ofcompartment 23 and may clasp thelid 28 in a closed position vialid catch 76. A spray ofwash liquid 50 may expel treatingchemistry 38 fromcavity 22 and may cleanrear wall 26 ofdispenser 20 of any residue ofchemistry 38 remaining after expulsion. Aspray 50 of wash liquid from within treatingchamber 14 may impinge ondispenser 20 directly or indirectly frominternal sprayers Dishwasher 10 may further comprise a separate sprayer (not shown) emitting a spray ofwash liquid 50 directly ontomovable element 30 in at least the extended 34 position. - Many other possible embodiments and configurations in addition to that shown in the above figures are contemplated by the present disclosure. To the extent not already described, the different features and structures of the various embodiments can be used in combination with each other as desired. That one feature cannot be illustrated in all of the embodiments is not meant to be construed that it cannot be, but is done for brevity of description. Thus, the various features of the different embodiments can be mixed and matched as desired to form new embodiments, whether or not the new embodiments are expressly described. Moreover, while “a set of” or “a plurality of” various elements have been described, it will be understood that “a set” or “a plurality” can include any number of the respective elements, including only one element. Combinations or permutations of features described herein are covered by this disclosure.
