Title: Dishwasher with door assembly

Description:
BACKGROUND 
     Contemporary automatic dishwashers for use in a typical household include a tub that can have an open front and at least partially defines a treating chamber into which items, such as kitchenware, glassware, and the like, can be placed to undergo a washing operation. At least one rack or basket for supporting soiled dishes can be provided within the tub. A spraying system with multiple sprayers can be provided for recirculating liquid throughout the tub to remove soils from the dishes. 
     The dishwasher can be provided with a door assembly, which can be pivotally mounted to the tub and that selectively closes the open front. The door assembly can include a panel defining a door front. A console can be included in the door assembly and can define or be coupled with various features for user interaction with the dishwasher. Such features can include, but are not limited to, a user interface, control buttons, an external handle, a pocket handle, and a door top surface. Such a console can be provided in at least two parts. In the case that the console is provided as two parts, there is often a pocket panel that is adhered to the front panel, and a console cap or fascia assembly that encloses the door from the top or can be provided as a user interface along the door top surface. This results in the need to use adhesive to join the two portions of the console, as well as to join the console pieces to the door front panel. This results in an assembly process requiring the use of adhesive, an added cost, as well as increased time and complexity.

     DETAILED DESCRIPTION 
       FIG. 1  is a schematic, side view of a dishwasher  10  for treating dishes according to an automatic cycle of operation, according to an aspect of the present disclosure. In  FIG. 1 , the dishwasher  10  includes a chassis  12  defining an interior. Depending on whether the dishwasher  10  is a stand-alone or built-in dishwasher, the chassis  12  can be a frame with or without panels attached, respectively. The dishwasher  10  shares many features of a conventional automatic dishwasher, which will not be described in detail herein except as necessary for a complete understanding of aspects of the disclosure. While aspects of the disclosure are described in terms of a conventional dishwashing unit, it can also be implemented in other types of dishwashing units, such as in-sink dishwashers, multi-tub dishwashers, or drawer-type dishwashers, as well as dishwashers having varying widths, sizes, and capacities. 
     A controller  14  can be located within the chassis  12  and can be operably coupled with various components of the dishwasher  10  to implement one or more cycles of operation. A control panel or user interface  16  can be provided on the dishwasher  10  and coupled with the controller  14 . The user interface  16  can be provided on the chassis  12  or on a door assembly  22  and 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  14  and receive information about the selected cycle of operation. 
     A tub  18  is located within the interior of and mounted to the chassis  12  and at least partially defines a treating chamber  20  with an access opening in the form of an open face. A cover, illustrated as the door assembly  22 , can be hingedly or pivotally mounted to the chassis  12  and can selectively move between an opened position, wherein the user can access the treating chamber  20 , and a closed position, as shown in  FIG. 1 , wherein the door assembly  22  covers or closes the open face of the treating chamber  20 . 
     Dish holders in the form of upper and lower racks  24 ,  26  are located within the treating chamber  20  and receive dishes for being treated. The racks  24 ,  26  define an interior and are mounted for slidable movement in and out of the treating chamber  20  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 the dishwasher  10 , including, without limitation; dishes, plates, pots, bowls, pans, glassware, silverware, and other utensils. While not shown, additional dish holders, such as a silverware basket on the interior of the door assembly  22  or a third level rack above the upper rack  24  can also be provided. 
     A spraying system  28  can be provided for spraying liquid into the treating chamber  20  and is illustrated in the form of an upper sprayer  30 , a mid-level sprayer  32 , a lower sprayer  34 , and a spray manifold  36 . The upper sprayer  30  can be located above the upper rack  24  and is illustrated as a fixed spray nozzle that sprays liquid downwardly within the treating chamber  20 . Mid-level sprayer  32  and lower sprayer  34  are located beneath upper rack  24  and lower rack  26 , respectively, and are illustrated as rotating spray arms. The mid-level sprayer  32  can provide a liquid spray upwardly through the bottom of the upper rack  24 . The lower sprayer  34  can provide a liquid spray upwardly through the bottom of the lower rack  26 . The mid-level sprayer  32  can optionally also provide a liquid spray downwardly onto the lower rack  26 , but for purposes of simplification, this will not be illustrated herein. 
     The spray manifold  36  can be fixedly mounted to the tub  18  adjacent to the lower rack  26  and can provide a liquid spray laterally through a side of the lower rack  26 . The spray manifold  36  is not limited to this position; rather, the spray manifold  36  can be located in any suitable part of the treating chamber  20 . While not illustrated herein, the spray manifold  36  can include multiple spray nozzles having apertures configured to spray wash liquid towards the lower rack  26 . The spray nozzles can be fixed or rotatable with respect to the tub  18 . Suitable spray manifolds are set forth in detail in U.S. Pat. No. 7,445,013, filed Jun. 17, 2003, and titled “Multiple Wash Zone Dishwasher,” and U.S. Pat. No. 7,523,758, filed Dec. 30, 2004, and titled “Dishwasher Having Rotating Zone Wash Sprayer,” both of which are incorporated herein by reference in their entirety. Instead of or in addition to the spray manifold  36  provided on the rear wall, nozzles can be provided on the right and left side walls of the tub  18 . 
     A liquid recirculation system can be provided for recirculating liquid from the treating chamber  20  to the spraying system  28 . The recirculation system can include a sump  38  and a pump assembly  40 . The sump  38  collects the liquid sprayed in the treating chamber  20  and can be formed by a sloped or recess portion of a bottom wall  42  of the tub  18 . The pump assembly  40  can include both a drain pump  44  and a recirculation pump  46 . 
     The liquid recirculation system can also be fluidly coupled with a water supply line  47  for receiving fresh water from a water supply source, such as a household water supply, as well as a water supply circuit. The water supply circuit comprises a household inlet fitting  60 , which is carried by the chassis  12 , a conduit  62  that fluidly couples the inlet fitting  60  to the tub  18 , and an actuatable valve  80 . The actuatable valve  80  selectively controls the flow of liquid through the conduit  62 , allowing the flow of liquid from the conduit  62  into the tub  18  when the actuatable valve  80  is in an opened position, and preventing the flow of liquid from the conduit  62  into the tub  18  when the actuatable valve  80  is in a closed position. 
     The drain pump  44  can draw liquid from the sump  38  and pump the liquid out of the dishwasher  10  to a household drain line  48 . The recirculation pump  46  can draw liquid from the sump  38  and pump the liquid through the spray system  28  to supply liquid into the treating chamber  20  through a supply tube  50  to one or more of the sprayers  30 ,  32 ,  34 ,  36 . In this manner, liquid can circulate from the sump  38  through the liquid recirculation system to the spray system  28  and back to the sump  38  to define a liquid recirculation circuit or flow path. 
     While the pump assembly  40  is illustrated as having separate drain and recirculation pumps  44 ,  46  in an alternative aspect, the pump assembly  40  can include a single pump configured to selectively supply wash liquid to either the spraying system  28  or the drain line  48 , such as by configuring the pump to rotate in opposite directions, or by providing a suitable valve system. 
     A heating system having a heater  52  can be located within or near the sump  38  for heating liquid contained in the sump  38 . The heater  52  can also heat air contained in the treating chamber  20 . Alternatively, a separate heating element (not shown) can be provided for heating the air circulated through the treating chamber  20 . A filtering system (not shown) can be fluidly coupled with the recirculation flow path for filtering the recirculated liquid. 
     A user-accessible dispensing system can be provided for storing and dispensing one or more treating chemistries to the treating chamber  20 . As shown herein, the user-accessible dispensing system can include a dispenser  54  mounted on an inside surface of the door assembly  22  such that the dispenser  54  is disposed in the treating chamber  20  when the door assembly  22  is in the closed position. The dispenser  54  is configured to dispense treating chemistry to the dishes within the treating chamber  20 . The dispenser  54  can have one or more compartments  56  closed by a dispenser door  58  on the inner surface of the door assembly  22 . The dispenser  54  can be a single use dispenser which holds a single dose of treating chemistry, a bulk dispenser which holds a bulk supply of treating chemistry and which is adapted to dispense a dose of treating chemistry from the bulk supply during a cycle of operation, or a combination of both a single use and bulk dispenser. 
     The dispenser  54  can further be configured to hold multiple different treating chemistries. For example, the dispenser  54  can have multiple compartments defining different chambers in which treating chemistries can be held. While shown as being disposed on the door assembly  22 , other locations of the dispenser  54  are possible. However, the dispenser  54  is positioned to be accessed by the user for refilling of the dispenser  54 , whether it is necessary to refill the dispenser  54  before each cycle (i.e. for a single user dispenser) or only periodically (i.e. for a bulk dispenser). 
       FIG. 2  is a schematic view of the controller  14  of the dishwasher  10  of  FIG. 1 . As illustrated schematically in  FIG. 2 , the controller  14  can be coupled with the heater  52  for heating the wash liquid during a cycle of operation, the drain pump  44  for draining liquid from the treating chamber  20 , the recirculation pump  46  for recirculating the wash liquid during the cycle of operation, the user-accessible dispenser  54  for selectively dispensing treating chemistry to the treating chamber  20 , and the actuatable valve  80  to selectively control the flow of liquid through the conduit  62  into the tub  18 . 
     The controller  14  can be provided with a memory  64  and a central processing unit (CPU)  66 . The memory  64  can be used for storing control software that can be executed by the CPU  66  in completing a cycle of operation using the dishwasher  10  and any additional software. For example, the memory  64  can store one or more pre-programmed cycles of operation that can be selected by a user and completed by the dishwasher  10 . A cycle of operation for the dishwasher  10  can include one or more of the following steps: a wash step, a rinse step, and a drying step. The wash step can further include a pre-wash step and a main wash step. The rinse step can also include multiple steps such as one or more additional rinsing steps performed in addition to a first rinsing. The amounts of water and/or rinse aid used during each of the multiple rinse steps can be varied. The drying step can have a non-heated drying step (so called “air only”), a heated drying step or a combination thereof. These multiple steps can also be performed by the dishwasher  10  in any desired combination. 
     The controller  14  can also receive input from one or more sensors  68 . Non-limiting examples of sensors  68  that can be communicably coupled with the controller  14  include a temperature sensor and turbidity sensor to determine the soil load associated with a selected grouping of dishes, such as the dishes associated with a particular area of the treating chamber  20 . 
     Turning now to  FIG. 3 , an exploded perspective view of a door panel assembly  100  that forms portions of the door assembly  22  of the dishwasher  10  is illustrated. While not illustrated, the door assembly  22  can also include an interior portion confronting the treating chamber  20  when the door assembly  22  is in the closed position, the interior portion including, by way of non-limiting example, the dispenser  54 . The door panel assembly  100  comprises a front door panel  102 , a single-piece console  104 , a handle  106 , at least one rotatable spacer  108 , a button tree  110 , and a light assembly  112 . 
     The front door panel  102  defines a door panel front surface  114 , side surfaces  116 , and a rear surface  158  ( FIG. 5 ). The side surfaces  116  are substantially perpendicular to the front surface  114 . At least one door panel flange  120  can extend from the side surfaces  116 , such that the door panel flange  120  is generally perpendicular to the side surfaces  116  and generally parallel to and spaced from the front surface  114 . Door panel flanges  120  on each of the side surfaces  116  extend inwardly toward each other. A console opening  118  can be provided within and defined by the front surface  114 . While the console opening  118  is illustrated herein as having a width less than the total width of the front surface  114  and positioned at an upper portion of the front surface  114 , it will be understood that the console opening  118  can have any suitable shape and position, including that it can extend the entire width of the front surface  114 . 
     The single-piece console  104  is defined by an integral or monolithic piece. The single-piece console  104  includes a panel on which there are inputs for controlling the dishwasher  10  or outputs for displaying status information for the dishwasher  10 . More specifically, a console front surface  126  and a top surface  122  that is substantially perpendicular to the console front surface  126  are included in the single-piece console  104 . The top surface  122  also forms the upper or top surface  122  for the door assembly  22 . 
     At least a portion of the console front surface  126  is configured to be received within the console opening  118 . The portion of the console front surface  126  received within the console opening  118  can be provided with a plurality of features. Non-limiting examples of such features include a pocket portion, illustrated herein as a pocket  124 , through which the handle  106  can be reached, a vent  128 , buttons, switches, or other inputs, printed graphics, which can be molded in or decorated in, decorative inserts, and a user interface. These features can be molded or formed into or with the single-piece console  104  or can be coupled with the single-piece console  104 . The decorative insert  156  ( FIG. 4 ) can be included on or otherwise mounted to the console front surface  126 . It will be understood that the buttons can be any suitable control setting device, non-limiting examples of which include switches, such as rocker switches, or rotating knobs or dials. While the pocket portion is illustrated herein as a pocket  124  through which the handle  106  can be reached, it will be understood that the handle  106  can instead be coupled to the single-piece console  104  without the need for a pocket  124 , such as by the use of a pull knob. 
     At least one rotatable spacer  108  is included within the door panel assembly  100 . In an exemplary aspect, two rotatable spacers  108  are provided, one at each side of the door panel assembly  100 . When the door panel assembly  100  is in an assembled condition, the rotatable spacer  108  is provided between a rear surface  130  of the single-piece console  104  and the front door panel  102 , specifically the door panel flange  120 . It will be understood that the rotatable spacer  108  can also be provided as a slide-in, separate, or removable spacer part. 
     When the door panel assembly  100  is in an assembled condition, the handle  106  is positioned to align with the pocket  124  on the console front surface  126 , such that a user can reach into the pocket  124  to contact the handle  106 . The handle  106  can be a handle  106  for providing a grip for a user, having no reciprocating latch elements, or the handle  106  can include movable components, such as a latch or lock for the door assembly  22 . Regardless of the type of handle  106 , a user can utilize the handle to move the door assembly  22  between opened and closed positions, selectively allowing access to the treating chamber  20 . The handle  106  can be coupled to the single-piece console  104  by any suitable mechanism including a snap attachment mechanism  160 , as illustrated. 
     The button tree  110  can be received by or coupled to the single-piece console  104 . Specifically, the single-piece console  104  can include openings or apertures  166  defined by the console front surface  126 , such that buttons  162  of the button tree  110  are received within the apertures  166  and presented to a user for interaction with the dishwasher  10 . While the button tree  110  is illustrated herein as a single monolithic piece connecting a plurality of buttons  162 , it will be understood that individual, non-connected buttons can also be contemplated. The button tree  110  can further include button stems  164  that provide a mechanical coupling between the buttons  162  presented to the user and switches coupled to the controller  14 , such that a user depressing the button  162  causes the button stem  164  to be correspondingly depressed to contact switches on the controller  14 . 
     The light assembly  112  can couple to the single-piece console  104  for illuminating buttons displayed to a user, or illuminating indicators, such as status displays. Specifically, the console front surface  126  can include illumination apertures  168  within which the light sources of the light assembly  112  can be received for displaying illumination to the user. The illumination apertures  168  can be provided as through-openings in the console front surface  126 , or could be transparent portions of the console front surface  126  such that light is transmitted through the illumination apertures  168 . The light assembly  112  can be any suitable source or structure for light emission, including but not limited to LEDs or an LED array that is coupled to the controller  14  in order to communicate status or display information to the user. 
       FIG. 4  illustrates the door panel assembly  100  in the assembled condition, with the decorative inserts  156 , vent  128 , pocket  124 , buttons  162 , and light assembly  112  in place. The vent  128  can be any suitable structure to allow the flow of air between the treating chamber  20  and the door panel assembly  100 , specifically to the console front surface  126 . While the vent  128  is illustrated herein as a plurality of fixed openings to allow air flow, it will be understood that the vent  128  can also include active components, such as a fan, blower, or motor assembly coupled to the vent  128 . While the button tree  110  and light assembly  112  are illustrated herein as being coupled to the console front surface  126 , it will be understood that the user interface, including the button tree  110  and the light assembly  112  can also be provided at the top surface  122  of the single-piece console  104 . 
       FIG. 5  illustrates an enlarged cross-sectional view of the single-piece console  104  mounted in the front door panel  102 . A first portion  170  of the console front surface  126  extends through the console opening  118 . It can be more easily seen from the cross-section that the console front surface  126  is contoured and that the first portion  170  that extends through the console opening  118  projects from a remainder of the console front surface  126 . A second portion  172  of the console front surface  126  is recessed to accommodate a project of an upper portion of the front door panel  102 . 
     A lower edge  174  adjacent the console front surface  126  defines an inverted U-shaped channel  132 . The U-shaped channel  132  is configured to receive the front surface  114  of the front door panel  102 , where the front surface  114  forms the console opening  118 . By way of non-limiting example, the U-shaped channel  132  can define a horizontal width of 1.4 millimeters and a vertical height of 3 millimeters. The receiving of the front surface  114  at the console opening  118  within the U-shaped channel  132  robustly couples the single-piece console  104  with the front door panel  102  so that undesired movement between the two pieces is restricted. The console front surface  126  can further form a protruding rib or protruding edge  154  that corresponds to and is received by the console opening  118 , for example by a snap-in attachment, to further secure the single-piece console  104  to the front door panel  102  in the appropriate alignment. The front door panel  102  can also include shapes or features to facilitate coupling with the single-piece console  104 , such as by securing, an interference fit, or a snap-in attachment. The top surface  122  of the single-piece console  104  can also be shaped to have a fit complementary to the front door panel  102 , such as at the second portion  172 , and also by interaction with a centering rib  152 , as discussed in detail with respect to  FIG. 6 . 
       FIG. 6  illustrates in more detail the rotatable spacer  108  in a first or initial installation position wherein the rotatable spacer  108  is substantially vertical and does not contact the door panel flange  120 . The rotatable spacer  108  comprises a pivot portion  136  at a lower end. The rotatable spacer  108  further comprises an inner arm  138  and an outer arm  140 . Each of the inner arm  138  and the outer arm  140  extend outwardly from the sides of the rotatable spacer  108 . Above the inner arm  138  and the outer arm  140  is a fastener portion  142  of the rotatable spacer  108 , which further defines a fastener opening  144 . At least one centering rib  152  is also formed by the single-piece console  104  to contact the side surfaces  116  of the front door panel  102  to ensure the single-piece console  104  is centered with the front door panel  102 . 
     The pivot portion  136  of the rotatable spacer  108  is coupled with the rear surface  130  of the single-piece console  104 . The rear surface  130  defines an inner arm rib  146  on which the inner arm  138  of the rotatable spacer  108  can rest when the rotatable spacer  108  occupies the initial installation position. It will be understood that the inner arm  138  need not rest on or be supported by the inner arm rib  146  in the initial installation position. Rather, the inner arm  138  can be positioned slightly above the inner arm rib  146 , such that the inner arm rib  146  prevents further inward rotational motion of the rotatable spacer  108 . A spacing rib  150  is also defined by the rear surface  130 . The rotatable spacer  108  is not in contact with the spacing rib  150  in the initial installation position. 
       FIG. 7  illustrates the view of  FIG. 6 , but with the rotatable spacer  108  rotated outwardly to a second or fully installed position, about the pivot portion  136 , where the rotatable spacer  108  is between the rear surface  130  of the single-piece console  104  and the door panel flange  120 . In the fully installed position, the inner arm  138  is no longer in contact with the inner arm rib  146 . The outer arm  140  overlies and extends behind the spacing rib  150 . In an exemplary aspect, the outer arm  140  can include a snap feature that couples to the spacing rib  150  in order to prevent the rotatable spacer  108  from rotating out of the fully installed position. The spacing rib  150  can resiliently bear against the outer arm  140 , providing a pressure to prevent undesired movement between the single-piece console  104  and the front door panel  102 . 
     In the fully installed position, the fastener portion  142  of the rotatable spacer  108  is positioned between the rear surface  130  and the door panel flange  120 . The fastener opening  144  is at least partially aligned with a flange fastener opening  134 , which is defined by the door panel flange  120 . When the rotatable spacer  108  is in the fully installed position, a fastener can pass through the flange fastener opening  134  and the fastener opening  144  to couple the single-piece console  104  and the front door panel  102  together. Any suitable type of fastener can be used, non-limiting examples of which include a screw, a plug, a snap-in feature, or a heat stake. Further, when the rotatable spacer  108  is in the fully installed position, a barrel nut opening  148  on the rear surface  130  is exposed for attachment of additional components of the door assembly  22 . 
     It will be understood that the door panel assembly  100  can be assembled in any suitable manner. By way of non-limiting example, the handle  106  can first be coupled to the single-piece console  104  via a snap-in attachment mechanism  160 . Next, the light assembly  112  and the button tree  110  are coupled to the single-piece console  104 , which can use a fastener or a snap-in attachment. The at least one rotatable spacer  108  is then coupled to the rear surface  130 . While the rotatable spacer  108  is illustrated herein as being a separate piece that is coupled to the rear surface  130 , it will also be understood that the rotatable spacer  108  can be formed with the rear surface  130  such that it is rotatable to the fully installed position, or the rotatable spacer  108  could be molded to the single-piece console  104  at another location, where it could be configured to be broken off or removed from the other location for attachment to the rear surface  130  at the time of installation. 
     The single-piece console  104  can then be coupled to the front door panel  102 . The single-piece console  104  is aligned with the console opening  118 , such that the U-shaped channel  132  receives the front surface  114  of the front door panel  102 . The protruding edge  154  of the single-piece console  104  can then be snapped into place within the console opening  118 . Rotation of the rotatable spacer  108  from the initial installation position to the fully installed position allows for the insertion of a fastener to join the single-piece console  104  to the door panel flange  120 . 
     The aspects described herein can be used to provide a single-piece console for use within a door panel assembly that simplifies and improves the installation and assembly process. While previous conventional approaches required the use of adhesive to form the console from more than one piece, resulting in increased cost, time, and complexity of assembly, the single-piece console of the present disclosure is ready for easy installation within the door panel assembly. The single-piece console also provides flexibility in manufacturing such that the same door panel piece can be used with the single-piece console whether it is desired for the user interface to be on the front surface or the top surface of the single-piece console. When the user interface is desired on the top panel, corresponding apertures for lights and puts can be included at the top surface and button trees and light sources can be attached to the top surface. Further, the inclusion of the rotatable spacer provides improved robustness to the door panel assembly and ensures proper installation. By having the rotatable spacer block the barrel nut opening in the initial installation position, it is ensured that the spacer must be rotated to the fully installed position before assembly of the door assembly can be completed. 
     It will also be understood that various changes and/or modifications can be made without departing from the spirit of the present disclosure. By way of non-limiting example, although the present disclosure is described for use with a door assembly pivotable about a horizontal axis, it will be recognized that the door assembly can be employed with various constructions, including door assemblies pivotable about a vertical axis and/or door assemblies for drawer-style dishwashers. 
     To the extent not already described, the different features and structures may be used in combination with each other as desired. That one feature may not be illustrated in all of the aspects of the disclosure is not meant to be construed that it cannot be, but is done for brevity of description. Thus, the various features of the different aspects of the disclosure may be mixed and matched as desired to form new aspects, whether or not the new aspects are expressly described. 
     While the aspects of the disclosure have been specifically described in connection with certain specific aspects thereof, it is to be understood that this is by way of illustration and not of limitation. Reasonable variation and modification are possible within the scope of the forgoing disclosure and drawings without departing from the spirit of the disclosure which is defined in the appended claims.
