[0020] The dishwasher 10 has a variety of systems, some of which are controllable, to implement the automatic cycle of operation. A cabinet 11 is provided to support the variety of systems needed to implement the automatic cycle of operation. As illustrated, for a built-in implementation, the cabinet 11 includes a frame in the form of a base 12 on which is supported an open-faced tub 14, which at least partially defines a treating chamber 16, having an open face 18, for receiving the dishes. A closure in the form of a door assembly 20 is pivotally mounted to the base 12 for movement between opened and closed positions to selectively open and close the open face 18 of the tub 14. Thus, the door assembly 20 provides selective accessibility to the treating chamber 16 for the loading and unloading of dishes or other items.
[0021] The cabinet 11, as in the case of the built-in dishwasher implementation, can be formed by other parts of the dishwasher 10, like the tub 14 and the door assembly 20, in addition to a dedicated frame structure, like the base 12, with them all collectively forming a uni-body frame to which the variety of systems are supported. In other implementations, like the drawer-type dishwasher, the cabinet 11 can be a tub that is slidable relative to a frame, with the closure being a part of the cabinet 11 or the countertop of the surrounding cabinetry. In a sink-type implementation, the sink forms the tub and the cover closing the open top of the sink forms the closure. Sink-type implementations are more commonly found in recreational vehicles.
[0022] The systems supported by the cabinet 11, while essentially limitless, can include dish holding system 30, spray system 40, recirculation system 50, drain system 60, water supply system 70, drying system 80, heating system 90, and filter system 63. These systems are used to implement one or more treating cycles of operation for the dishes, for which there are many, and one of which includes a traditional automatic wash cycle.
[0023] A basic traditional automatic wash cycle of operation has a wash phase, where a detergent/water mixture is recirculated and then drained, which is then followed by a rinse phase where water alone or with a rinse agent is recirculated and then drained. An optional drying phase can follow the rinse phase. More commonly, the automatic wash cycle has multiple wash phases and multiple rinse phases. The multiple wash phases can include a pre-wash phase where water, with or without detergent, is sprayed or recirculated on the dishes, and can include a dwell or soaking phase. There can be more than one pre-wash phase. A wash phase, where water with detergent is recirculated on the dishes, follows the pre-wash phases. There can be more than one wash phase; the number of which can be sensor controlled based on the amount of sensed soils in the wash liquid. One or more rinse phases will follow the wash phase(s), and, in some cases, come between wash phases. The number of wash phases can also be sensor controlled based on the amount of sensed soils in the rinse liquid. The wash phases and rinse phases can include the heating of the water, even to the point of one or more of the phases being hot enough for long enough to sanitize the dishes. A drying phase can follow the rinse phase(s). The drying phase can include a drip dry, heated dry, condensing dry, air dry or any combination.
[0024] A controller 22 can also be included in the dishwasher 10 and operably couples with and controls the various components of the dishwasher 10 to implement the cycle of operation. The controller 22 can be located within the door assembly 20 as illustrated, or it can alternatively be located somewhere within the cabinet 11. The controller 22 can also be operably coupled with a control panel or user interface 24 for receiving user-selected inputs and communicating information to the user. The user interface 24 can include operational controls such as dials, lights, switches, and displays enabling a user to input commands, such as a cycle of operation, to the controller 22 and receive information.
[0025] While the user interface 24 is illustrated along a top surface of the door assembly 20, it is contemplated the user interface can be provided on any suitable portion of the door assembly 20, including a front surface or a side surface in some non-limiting examples. In some implementations, the user interface 24 can include multiple interfaces, control panels, indicators, or the like. Such multiple interfaces can be positioned on a single surface of the door assembly 20, or on multiple surfaces of the door assembly 20, such as a first user interface on a top surface and a second user interface on an outer surface in one example. The user interface 24 can include any suitable type or number of interfaces, control panels, indicators, or the like.
[0026] The dish holding system 30 can include any suitable structure for holding dishes within the treating chamber 16. Exemplary dish holders are illustrated in the form of an upper dish racks 32 and a lower dish rack 34, commonly referred to as racks, which are located within the treating chamber 16. The upper dish racks 32 and the lower dish rack 34 are typically mounted for slidable movement in and out of the treating chamber 16 through the open face 18 for ease of loading and unloading. Drawer guides/slides/rails 36 are typically used to slidably mount the upper dish rack 32 to the tub 14. The lower dish rack 34 typically has wheels or rollers 38 that roll along rails 39 formed in sidewalls of the tub 14 and onto the door assembly 20, when the door assembly 20 is in the opened position.
[0027] Dedicated dish holders can also be provided. One such dedicated dish holder is a third level rack 28 located above the upper dish rack 32. Like the upper dish rack 32, the third level rack is slidably mounted to the tub 14 with drawer guides/slides/rails 36. The third level rack 28 is typically used to hold utensils, such as tableware, spoons, knives, spatulas, etc., in an on-the-side or flat orientation. However, the third level rack 28 is not limited to holding utensils. If an item can fit in the third level rack, it can be washed in the third level rack 28. The third level rack 28 generally has a much shorter height or lower profile than the upper and the lower dish racks 32, 34. Typically, the height of the third level rack is short enough that a typical glass cannot be stood vertically in the third level rack 28 and the third level rack 28 still slide into the treating chamber 16.
[0028] Another dedicated dish holder can be a silverware basket (not shown), which is typically carried by one of the upper or the lower dish racks 32, 34 or mounted to the door assembly 20. The silverware basket typically holds utensils and the like in an upright orientation as compared to the on-the-side or flat orientation of the third level rack 28.
[0029] A dispenser assembly 48 is provided to dispense treating chemistry, e.g. detergent, anti-spotting agent, etc., into the treating chamber 16. The dispenser assembly 48 can be mounted on an inner surface of the door assembly 20, as shown, or can be located at other positions within the cabinet 11. The dispenser assembly 48 can dispense one or more types of treating chemistries. The dispenser assembly 48 can be a single-use dispenser or a bulk dispenser, or a combination of both.
[0030] Turning to
[0031] The deep-clean sprayer 44 is a manifold extending along a rear wall of the tub 14 and has multiple nozzles 46, with multiple apertures 47, generating an intensified and/or higher pressure spray than the upper spray arm 41, the lower spray arm 42, or the third level sprayer 43. The nozzles 46 can be fixed or move, such as in rotating. The spray emitted by the deep-clean sprayer 44 defines a deep clean zone, which is illustrated along a rear side of the lower dish rack 34. Thus, dishes needing deep cleaning, such as dishes with baked-on food, can be located in the lower dish rack 34 to face the deep-clean sprayer 44. The deep-clean sprayer 44, while illustrated as only one unit on a rear wall of the tub 14 could include multiple units and/or extend along multiple portions, including different walls, of the tub 14, and can be provide above, below or beside any of the dish holders with deep-cleaning is desired.
[0032] The spot sprayer 45, like the deep-clean sprayer, can emit an intensified and/or higher-pressure spray, especially to a discrete location within one of the dish holders. While the spot sprayer 45 is shown below the lower dish rack 34, it could be adjacent to any part of any dish holder or along any wall of the tub where special cleaning is desired. In the illustrated location below the lower dish rack 34, the spot sprayer can be used independently of or in combination with the lower spray arm 42. The spot sprayer 45 can be fixed or can move, such as in rotating.
[0033] These five sprayers are illustrative examples of suitable sprayers and are not meant to be limiting as to the type of suitable sprayers.
[0034] The recirculation system 50 recirculates the liquid sprayed into the treating chamber 16 by the sprayers of the spray system 40 back to the sprayers to form a recirculation loop or circuit by which liquid can be repeatedly sprayed, continuously sprayed, or any combination thereof onto dishes in the dish holders. The recirculation system 50 can include a sump 51 and a pump assembly 52. The sump 51 collects the liquid sprayed in the treating chamber 16 and can be formed by a sloped or recess portion of a bottom wall of the tub 14. The pump assembly 52 can include one or more pumps such as recirculation pump 53. The sump 51 can also be a separate module that is affixed to the bottom wall and include the pump assembly 52.
[0035] Multiple supply conduits 54, 55, 56, 57, 58 fluidly couple the sprayers 43, 44, 45, 49 to the recirculation pump 53. A recirculation valve 59 can selectively fluidly couple each of the conduits 54-58 to the recirculation pump 53. While each sprayer 43, 44, 45, 49 is illustrated as having a corresponding dedicated supply conduit 54-58 one or more subsets, comprising multiple sprayers from the total group of sprayers 43, 44, 45, 49, can be supplied by the same conduit, negating the need for a dedicated conduit for each sprayer. For example, a single conduit can supply the upper spray arm 41 and the third level sprayer 43. Another example is that the sprayer 49 is supplied liquid by the conduit 56, which also supplies the third level sprayer 43.
[0036] The recirculation valve 59, while illustrated as a single valve, can be implemented with multiple valves. Additionally, one or more of the conduits can be directly coupled to the recirculation pump 53, while one or more of the other conduits can be selectively coupled to the recirculation pump with one or more valves. There are essentially an unlimited number of plumbing schemes to connect the recirculation system 50 to the spray system 40. The illustrated plumbing is not limiting.
[0037] A drain system 60 drains liquid from the treating chamber 16. The drain system 60 can include a drain pump 61 fluidly coupling the treating chamber 16 to a drain line 62. As illustrated the drain pump 61 can fluidly couple the sump 51 to the drain line 62.
[0038] While separate recirculation pumps 53 and drain pumps 62 are illustrated, a single pump can be used to perform both the recirculating and the draining functions. Alternatively, the drain pump 61 can be used to recirculate liquid in combination with the recirculation pump 53. When both a recirculation pump 53 and drain pump 61 are used, the drain pump 61 is typically more robust than the recirculation pump 53 as the drain pump 61 tends to have to remove solids and soils from the sump 51, unlike the recirculation pump 53, which tends to recirculate liquid which has solids and soils filtered away to some extent.
[0039] A water supply system 70 is provided for supplying fresh water to the dishwasher 10 from a household water supply via a household water valve 71. The water supply system 70 includes a water supply unit 72 having a water supply conduit 73 with a siphon break 74. While the water supply conduit 73 can be directly fluidly coupled to the tub 14 or any other portion of the dishwasher 10, the water supply conduit is shown fluidly coupled to a supply tank 75, which can store the supplied water prior to use. The supply tank 75 is fluidly coupled to the sump 51 by a supply line 76, which can include a controllable valve 77 to control when water is released from the supply tank 75 to the sump 51.
[0040] The supply tank 75 can be conveniently sized to store a predetermined volume of water, such as a volume required for a phase of the cycle of operation, which is commonly referred to as a charge of water. The storing of the water in the supply tank 75 prior to use is beneficial in that the water in the supply tank 75 can be treated in some manner, such as softening or heating prior to use.
[0041] A water softener 78 is provided with the water supply system 70 to soften the fresh water. The water softener 78 is shown fluidly coupling the water supply conduit 73 to the supply tank 75 so that the supplied water automatically passes through the water softener 78 on the way to the supply tank 75. However, the water softener 78 could directly supply the water to any other part of the dishwasher 10 than the supply tank 75, including directly supplying the tub 14. Alternatively, the water softener 78 can be fluidly coupled downstream of the supply tank 75, such as in-line with the supply line 76. Wherever the water softener 78 is fluidly coupled, it can be done so with controllable valves, such that the use of the water softener 78 is controllable and not mandatory.
[0042] A drying system 80 is provided to aid in the drying of the dishes during the drying phase. The drying system as illustrated includes a condensing assembly 81 having a condenser 82 formed of a serpentine conduit 83 with an inlet fluidly coupled to an upper portion of the tub 14 and an outlet fluidly coupled to a lower portion of the tub 14, whereby moisture laden air within the tub 14 is drawn from the upper portion of the tub 14, passed through the serpentine conduit 83, where liquid condenses out of the moisture laden air and is returned to the treating chamber 16 where it ultimately evaporates or is drained via the drain pump 61. The serpentine conduit 83 can be operated in an open loop configuration, where the air is exhausted to atmosphere, a closed loop configuration, where the air is returned to the treating chamber, or a combination of both by operating in one configuration and then the other configuration.
[0043] To enhance the rate of condensation, the temperature difference between the exterior of the serpentine conduit 83 and the moisture laden air can be increased by cooling the exterior of the serpentine conduit 83 or the surrounding air. To accomplish this, an optional cooling tank 84 is added to the condensing assembly 81, with the serpentine conduit 83 being located within the cooling tank 84. The cooling tank 84 is fluidly coupled to at least one of the spray system 40, recirculation system 50, drain system 60 or water supply system 70 such that liquid can be supplied to the cooling tank 84. The liquid provided to the cooling tank 84 from any of the systems 40-70 can be selected by source, by phase of cycle of operation, or any combination thereof such that the liquid is at a lower temperature than the moisture laden air or even lower than the ambient air.
[0044] As illustrated, the liquid is supplied to the cooling tank 84 by the drain system 60. A valve 85 fluidly connects the drain line 62 to a supply conduit 86 fluidly coupled to the cooling tank 84. A return conduit 87 fluidly connects the cooling tank 84 back to the treating chamber 16 via a return valve 79. In this way a fluid circuit is formed by the drain pump 61, drain line 62, valve 85, supply conduit 86, cooling tank 84, return valve 79 and return conduit 87 through which liquid can be supplied from the treating chamber 16, to the cooling tank 84, and back to the treating chamber 16. Alternatively, the supply conduit 86 could fluidly couple to the drain line 62 if re-use of the water is not desired.
[0045] To supply cold water from the household water supply via the household water valve 71 to the cooling tank 84, the water supply system 70 would first supply cold water to the treating chamber 16, then the drain system 60 would supply the cold water in the treating chamber 16 to the cooling tank 84. It should be noted that the supply tank 75 and cooling tank 84 could be configured such that one tank performs both functions.
[0046] The drying system 80 can use ambient air, instead of cold water, to cool the exterior of the serpentine conduit 83. In such a configuration, a blower 88 is connected to the cooling tank 84 and can supply ambient air to the interior of the cooling tank 84. The cooling tank 84 can have a vented top 89 to permit the passing through of the ambient air to allow for a steady flow of ambient air blowing over the serpentine conduit 83.
[0047] The cooling air from the blower 88 can be used in lieu of the cold water or in combination with the cold water. The cooling air will be used when the cooling tank 84 is not filled with liquid. Advantageously, the use of cooling air or cooling water, or combination of both, can be selected on the site-specific environmental conditions. If ambient air is cooler than the cold water temperature, then the ambient air can be used. If the cold water is cooler than the ambient air, then the cold water can be used. Cost-effectiveness can also be considered when selecting between cooling air and cooling water. The blower 88 can be used to dry the interior of the cooling tank 84 after the water has been drained. Suitable temperature sensors for the cold water and the ambient air can be provided and send their temperature signals to the controller 22, which can determine which of the two is colder at any time or phase of the cycle of operation.
[0048] A heating system 90 is provided for heating water used in the cycle of operation. The heating system 90 includes a heater 92, such as an immersion heater, located in the treating chamber 16 at a location where it will be immersed by the water supplied to the treating chamber 16. The heater 92 need not be an immersion heater, it can also be an in-line heater located in any of the conduits. There can also be more than one heater 92, including both an immersion heater and an in-line heater.
[0049] The heating system 90 can also include a heating circuit 93, which includes a heat exchanger 94, illustrated as a serpentine conduit 95, located within the supply tank 75, with a supply conduit 96 supplying liquid from the treating chamber 16 to the serpentine conduit 95, and a return conduit 97 fluidly coupled to the treating chamber 16. The heating circuit 93 is fluidly coupled to the recirculation pump 53 either directly or via the recirculation valve 59 such that liquid that is heated as part of a cycle of operation can be recirculated through the heat exchanger 94 to transfer the heat to the charge of fresh water residing in the supply tank 75. As most wash phases use liquid that is heated by the heater 92, this heated liquid can then be recirculated through the heating circuit 93 to transfer the heat to the charge of water in the supply tank 75, which is typically used in the next phase of the cycle of operation.
[0050] A filter system 63 is provided to filter un-dissolved solids from the liquid in the treating chamber 16. The filter system 63 includes a coarse filter 64 and a fine filter 65, which can be a removable basket 66 residing the sump 51, with the coarse filter 64 being a screen 67 circumscribing the removable basket 66. Additionally, the recirculation system 50 can include a rotating filter in addition to or in place of either or both of the coarse filter 64 and fine filter 65. Other filter arrangements are contemplated such as an ultrafiltration system.
[0051] As illustrated schematically in
[0052] Referring now to
[0053] The outer panel 102 can also extend from a bottom edge 106 to a top edge 107. The bottom edge 106 of the outer panel 102 can define a bottom of the door assembly 100 where the door assembly is pivotally mounted to the base 12. The top edge 107 can be defined by upper terminal edges of the front face 104, the left sidewall 108, and the right sidewall 109. The top edge 107 can optionally be an open top edge 110 closed by a top cap 120.
[0054] A pocket opening 112 extends completely across the front face 104 and partially into each of the left and right sidewalls 108, 109. A portion of the pocket opening 112 along the left side wall 108 can define a left notch 118, as shown. Another portion of the pocket opening 112 along the right side wall 109 can define a right notch 119, as shown. A periphery 114 along the outer panel 102 defines an outside surface of the pocket opening 112. The door assembly 100 can further include a pocket handle assembly 130 coupled to the outer panel 102 and accessible through the pocket opening 112.
[0055] The outer panel 102, as illustrated, is formed from a single piece and has the pocket opening 112 formed in the single piece, which provides a continuous appearance for the outer panel 102. The outer panel 102, as discussed herein, is unlike prior outer panels, which were typically made of multiple pieces and have the opening formed at a junction of the multiple pieces. When the outer panel is made from metal, such as stainless steel, the outer panel is often stamped and the single piece is more aesthetically desirable. However, having a single piece outer panel comes with the complication of how to include the pocket handle assembly, which was previously just attached to a terminal end of the front face. The pocket opening 112, as discussed herein, is extended completely across the front face 104 and partially into each of the left and right sidewalls 108, 109 of the single piece, which provides access to the pocket handle assembly 130 and has the periphery 114 providing a surface for coupling the pocket handle assembly 130 to the outer panel 102.
[0056] The outer panel 102 can optionally include a vent or one or more apertures in the form of slots, holes, or other openings (not shown) in the outer panel 102 through which one of air, moisture, light, or combinations thereof can pass and can be provided on one or more of the front face 104, the left sidewall 108, the right sidewall 109, or a combination of both.
[0057] Turning to
[0058] The top cap 120 includes front and rear flanges 122, 123, spaced-apart left and right cap sidewalls 124, 125, and a top surface 126, as illustrated. The front and rear flanges 122, 123 and the left and right cap sidewalls 124, 125 can collectively define a periphery of the top surface 126. The front and rear flanges 122, 123 and the left and right cap sidewalls 124, 125 can also extend downward from the top surface 126, as illustrated.
[0059] When installed to the outer panel 102, an edge of the top surface 126 of the top cap 120 can be located on or adjacent to the top edge 107 of the outer panel 102. Thus, the top cap 120 of the door assembly 100 closes the open top edge 110 of the outer panel 102. The top edge 107 of the outer panel 102 can include a seat on which to receive one of the left cap sidewall 124, right cap sidewall 125, front flange 122, rear flange 123, or any combination thereof. The left and right cap sidewalls 124, 125 can couple to respective left and right sidewalls 108, 109 of the outer panel 102.
[0060] The outer panel 102 can optionally include a fastening element (not shown) at the top edge 107 for securing the top cap 120 to the outer panel 102.
