[0024] FIGS. 1 and 2 depict an example domestic dishwasher or dishwashing appliance 100 that may be configured in accordance with aspects of the present disclosure. For the particular embodiment of FIGS. 1 and 2, the dishwasher appliance 100 includes a cabinet 102 (FIG. 2) having a tub 104 therein that defines a wash chamber 106 for receipt of articles 94 for washing. As shown in FIG. 2, tub 104 extends between a top 107 and a bottom 108 along a vertical direction V, between a pair of opposing side walls 110 along a lateral direction L, and between a front side 111 and a rear side 112 along a transverse direction T. Each of the vertical direction V, lateral direction L, and transverse direction T are mutually perpendicular to one another.

[0025] In this regard, as used herein, the terms cabinet, housing, and the like are generally intended to refer to an outer frame or support structure for appliance 100, e.g., including any suitable number, type, and configuration of support structures formed from any suitable materials, such as a system of elongated support members, a plurality of interconnected panels, or some combination thereof. It should be appreciated that cabinet 102 does not necessarily require an enclosure and may simply include open structure supporting various elements of appliance 100. By contrast, cabinet 102 may enclose some or all portions of an interior of cabinet 102. It should be appreciated that cabinet 102 may have any suitable size, shape, and configuration while remaining within the scope of the present subject matter.

[0026] The tub 104 includes a front opening 114 and a door 116 hinged at its bottom 117 for movement between a normally closed vertical position (shown in FIG. 1), wherein the wash chamber 106 is sealed shut for washing operation, and a horizontal open position for loading and unloading of articles from the dishwasher appliance 100. According to example embodiments, dishwasher appliance 100 further includes a door closure mechanism or assembly 118 that is used to lock and unlock door 116 for accessing and sealing wash chamber 106.

[0027] At least one rack assembly is slidably positioned within wash chamber 106 and is configured for the receipt of articles for cleaning. For the example embodiment shown in FIG. 2, opposing tub sidewalls 110 accommodate a plurality of rack assemblies. More specifically, guide rails 96, 98 and 120 may be mounted to (or formed as part of) sidewalls 110 for supporting a first rack assembly 122 (also referred to as a lower rack assembly 122), a middle rack assembly 124 (also referred to as a second rack assembly 124), and a third rack assembly 126 (also referred to as an upper rack assembly 126). As illustrated, upper rack assembly 126 is positioned at a top portion of wash chamber 106 above middle rack assembly 124, which is positioned above lower rack assembly 122 along the vertical direction V. Additional details regarding the upper rack assembly 126 will be provided herein. For this example embodiment, upper rack assembly 126 is supported on opposing sidewalls 110 by rails 120 but rails 120 could be supported on and attached to middle rack assembly 124 as well.

[0028] Each rack assembly 122, 124, 126 is adapted for movement along transverse direction T between an extended loading position (not shown) in which the rack is substantially positioned outside the wash chamber 106, and a retracted position (shown in FIGS. 1 and 2) in which the rack is located inside the wash chamber 106. This may be facilitated, for example, by rollers, or guide wheels 128 mounted onto rack assemblies 122, 124, 126, respectively. Although guide rails 96, 98, 120 and guide wheels 128 are illustrated herein as facilitating movement of the respective rack assemblies 122, 124, 126, it should be appreciated that any suitable sliding mechanism or member may be used according to alternative embodiments. In some embodiments, dishwasher appliance 100 may accommodate a different number of rack assemblies and supporting guide rails. For example, dishwasher appliance 100 may accommodate only first rack assembly 122 and upper rack assembly 126, with accompanying guide rails.

[0029] Some or all of the rack assemblies 122, 124, 126 may be fabricated into lattice, or grid, structures including a plurality of wires or elongated members 130 (for clarity of illustration, not all elongated members making up rack assemblies 122, 124, 126 are shown in FIG. 2). The plurality of wires or elongated members 130 may be either steel and stainless steel, and the wire may be coated with none, one, or more of nylon and polyvinyl chloride. Rack assemblies 122, 124, 126 are generally configured for supporting articles 94 within wash chamber 106 while allowing a flow of wash fluid to reach and impinge on those articles, e.g., during a cleaning or rinsing cycle. For some embodiments, a silverware basket (not shown) is removably attached to a rack assembly, e.g., lower rack assembly 122, for placement of silverware, utensils, and the like, that are otherwise too small or delicate to be accommodated by rack 122.

[0030] At least one spray assembly is located in wash chamber 106 and is configured to direct wash fluids onto at least on rack assembly for washing articles located therein. For the example embodiment of FIG. 2, dishwasher appliance 100 further includes a plurality of spray assemblies for urging a flow of water or wash fluid onto the articles placed within wash chamber 106. More specifically, as illustrated in FIG. 2, dishwasher appliance 100 includes a first spray assembly 134 (also referred to as a lower spray arm assembly 134) disposed in a lower region 136 of wash chamber 106 and above a sump 138 so as to rotate in relatively close proximity to lower rack assembly 122. Similarly, a second spray assembly 140 (also referred to as a mid-level spray arm assembly 140) is located in an upper region 137 of wash chamber 106 and may be located below and in close proximity to middle rack assembly 124. In this regard, mid-level spray arm assembly 140 may generally be configured for urging a flow of wash fluid up through middle rack assembly 124 and third rack assembly 126. Additionally, an upper or third spray assembly 142 (also referred to as an upper spray assembly 142) may be located above upper or third rack assembly 126 along the vertical direction V. In this manner, third spray assembly 142 may be configured for urging and/or cascading a flow of wash fluid downward over rack assemblies 122, 124, and 126.

[0031] The various spray assemblies and manifolds described herein may be part of a fluid distribution system or fluid circulation assembly 150 for circulating water and wash fluid in the tub 104. More specifically, fluid circulation assembly 150 includes a pump 152 for circulating water and wash fluid (e.g., detergent, water, and/or rinse aid) in the tub 104. Pump 152 may be located within sump 138 or within a machinery compartment located below sump 138 of tub 104, as generally recognized in the art. Fluid circulation assembly 150 may include one or more fluid conduits or circulation piping for directing water and/or wash fluid from pump 152 to the various spray assemblies and manifolds. For example, as illustrated in FIG. 2, a primary supply conduit 154 may extend from pump 152, along rear side 112 of tub 104 along the vertical direction V to supply wash fluid throughout wash chamber 106. In some examples, a secondary supply conduit (not shown) may supply additional wash fluid to one or more various spray assemblies and manifolds.

[0032] As illustrated, primary supply conduit 154 is used to supply wash fluid to mid-level spray arm assembly 140 while a secondary supply conduit 92 supplies wash fluid to upper spray assembly 142. Diverter assembly 156 can allow selection between spray assemblies 134 and 140, 142 being supplied with wash fluid. However, it should be appreciated that according to alternative embodiments, any other suitable plumbing configuration may be used to supply wash fluid throughout the various spray manifolds and assemblies described herein.

[0033] Each spray assembly 134, 140, 142 or other spray device may include an arrangement of discharge ports or orifices for directing wash fluid received from pump 152 onto dishes or other articles located in wash chamber 106. The arrangement of the discharge ports, also referred to as jets, apertures, or orifices, may provide a rotational force by virtue of wash fluid flowing through the discharge ports. Alternatively, spray assemblies 134, 140, 142 may be motor-driven, or may operate using any other suitable drive mechanism. Spray manifolds and assemblies may also be stationary. Movement of the spray arm assemblies 134 and 140 and the spray from fixed manifolds like spray assembly 142 provides coverage of dishes, silverware, and other dishwasher contents and articles 94 to be cleaned with a washing spray. Other configurations of spray assemblies may be used as well. For example, dishwasher appliance 100 may have additional spray assemblies for cleaning silverware, for scouring casserole dishes, for spraying pots and pans, for cleaning bottles, etc. One skilled in the art will appreciate that the embodiments discussed herein are used for the purpose of explanation only and are not limitations of the present subject matter.

[0034] In operation, pump 152 draws wash fluid in from sump 138 and pumps it to a diverter assembly 156, e.g., which is positioned within sump 138 of dishwasher appliance. Diverter assembly 156 may include a diverter disk (not shown) disposed within a diverter chamber (not shown) for selectively distributing the wash fluid to the spray assemblies 134, 140, 142 and/or other spray manifolds or devices. For example, the diverter disk may have a plurality of apertures that are configured to align with one or more outlet ports (not shown) at the top of diverter chamber (not shown). In this manner, the diverter disk may be selectively rotated to provide wash fluid to the desired spray device.

[0035] According to an example embodiment, diverter assembly 156 is configured for selectively distributing the flow of wash fluid from pump 152 to various fluid supply conduits, only some of which (e.g., 154) are illustrated in FIG. 2 for clarity. More specifically, diverter assembly 156 may include four outlet ports (not shown) for supplying wash fluid to a first conduit for rotating lower spray arm assembly 134 in the clockwise direction, a second conduit for rotating lower spray arm assembly 134 in the counterclockwise direction, a third conduit for spraying rack assembly 126 (shown in FIG. 2) as a silverware rack, and a fourth conduit for supplying only mid-level and/or upper spray assemblies 140, 142. Other configurations of diverter assembly 156 and/or other components (e.g., valves) may be used to allow various choices in the operation of the spray assemblies 134, 140, and 142 during a cleaning cycle.

[0036] The dishwasher appliance 100 is further equipped with a controller 160 (FIG. 2) to regulate operation of the dishwasher appliance 100. Controller 160 may include one or more memory devices and one or more microprocessors, such as general or special purpose microprocessors operable to execute programming instructions or micro-control code associated with a cleaning cycle. The memory may represent random access memory such as DRAM or read only memory such as ROM or FLASH. In one embodiment, the processor executes programming instructions stored in memory. The memory may be a separate component from the processor or may be included onboard within the processor. Alternatively, controller 160 may be constructed without using a microprocessor, e.g., using a combination of discrete analog and/or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software.

[0037] The controller 160 may be positioned in a variety of locations throughout dishwasher appliance 100. In the illustrated embodiment, the controller 160 may be located within a control panel area 162 of door 116. In such an embodiment, input/output (I/O) signals may be routed between the control system and various operational components of dishwasher appliance 100 along wiring harnesses that may be routed through the bottom of door 116. Typically, the controller 160 includes a user interface panel/controls 164 (FIG. 1) through which a user may select various operational features and modes and monitor progress of the dishwasher appliance 100. In one embodiment, the user interface 164 may represent a general purpose I/O (GPIO) device or functional block. In one embodiment, the user interface 164 may include input components, such as one or more of a variety of electrical, mechanical, or electro-mechanical input devices including rotary dials, push buttons, and touch pads. The user interface 164 may include a display component, such as a digital or analog display device designed to provide operational feedback to a user. The user interface 164 may be in communication with the controller 160 via one or more signal lines or shared communication busses.

[0038] It should be appreciated that the invention is not limited to any particular style, model, or configuration of dishwasher appliance 100. The example embodiment depicted in FIGS. 1 and 2 is for illustrative purposes only. For example, different locations may be provided for user interface 164, different configurations, including providing one or more rack assemblies 122, 124, 126 and one or more spray assemblies 134, 140, 142, to dishwasher appliance 100 may be used, different configurations may be provided for rack assemblies 122, 124, 126, different spray assemblies 134, 140, 142 and spray manifold configurations may be used, and other differences may be applied while remaining within the scope of the present subject matter.

[0039] Shown in FIGS. 3 and 4, the perimeter of third rack assembly 126 may be defined by a wire framework 300. Wire framework 300 may include a floor 308 formed in combination with the floor portion of wire insert 302. Wire insert 302 may include at least two (2) of a hook 306, or the like, for removably coupling wire insert 302 to wire framework 300. The present example embodiment includes four (4) hooks 306. Wire insert 302 may be defined in the transverse direction T, between a first boundary wall 310 and a second boundary wall 312, whereupon hooks 306 may be positioned. In FIG. 3, wire insert 302 is shown coupled to wire framework 300 via hooks 306. In FIG. 4, wire insert 302 is shown removed from wire framework 300 with respect to the vertical direction V. Wire insert 302 may include an upper floor portion 314 and a lower floor portion 316. The upper floor portion 314 and the lower floor portion 316 may be positioned at different heights with respect to the vertical direction V such that different size articles for washing may be placed upon wire insert 302. Lower floor portion 316 may be configured to interface, e.g., minimal gap, with floor 308 when wire insert 302 is inserted in wire framework 300. Thus, e.g., floor 308 may be nested against wire insert 302 when wire insert 302 is inserted in wire framework 300. Moreover, lower floor portion 316 may be positioned generally coplanar with floor 308 such that lower floor portion 316 and floor 308 may collectively form a portion of the floor of third rack assembly 126.

[0040] Referring still to FIGS. 3 and 4, wire framework 300 may further include a third boundary wall 311 at a first side portion 313 and a fourth boundary wall 315 at a second side portion 317. Third boundary wall 311 at first side portion 313 and fourth boundary wall 315 at second side portion 317 may be configured for enclosing third rack assembly 126 with respect to the lateral direction L. First boundary wall 310 and second boundary wall 312 of wire insert 302 may enclose third rack assembly 126 with respect to the transverse direction T.

[0041] Shown in FIGS. 5-7, another example embodiment of third rack assembly 126 may be defined by a wire framework 300. Wire framework 300 may include a floor 308 and a wire insert 302 forming a first floor portion and a second floor portion, respectively, of a floor of third rack assembly 126. Wire insert 302 may include at least two (2) of a hook 306, or the like, for coupling wire insert 302 to wire framework 300. The present example embodiment includes four (4) hooks 306. Wire insert 302 may be defined in the transverse direction T, between a first boundary wall 310 and a second boundary wall 312, whereupon hooks 306 may be positioned. Wire insert 302 may include an upper floor portion 314 and a lower floor portion 316. The upper floor portion 314 and the lower floor portion 316 may be positioned at different heights with respect to the vertical direction, V, such that different size articles for washing may be placed upon wire insert 302.

[0042] As discussed in greater detail below, wire insert 302 may be translatable relative to wire framework 300, e.g., along the lateral direction L. For example, hooks 306 may slide on wires of wire framework 300 as wire insert 302 translates relative to wire framework 300, e.g., along the lateral direction L. As an example, wire insert 302 may be translatable relative to wire framework 300 between the positions shown in FIGS. 5 and 7. A user may adjust the position of wire insert 302 on wire framework 300 in order to allow taller items to be placed on a rack (not shown) below third rack assembly 126 with interfering with wire insert 302.

[0043] Lower floor portion 316 may include a handle 320 welded to the wires of lower floor portion 316 at weld spots 322. Handle 320 may extend in the transverse direction T. FIG. 6 provides an alternative embodiment of handle 320, where handle 320 is a continuation of the existing wire of lower floor portion 316, rather than an additional, welded handle piece. As illustrated in FIG. 7, a user may grasp handle 320 and translate wire insert 302 along the lateral direction L. Additional or alternative embodiments may exist where a user may grasp handle 320 and translate wire insert 302 along the transverse direction T. Handle 320 may show a user the intended translation of third rack assembly 126, e.g., perpendicular or parallel to tub 104. Third rack assembly 126 may be perceived as shallow and hidden at the top of dishwasher appliance 100, so handle 320 may aid in communicating to a user the location of third rack assembly 126 when viewing dishwasher appliance 100 from above. Additionally or alternatively, wire insert 302 may include both handles 320 that extend in the transverse direction T and vertical direction V.

[0044] Shown in FIG. 8 is another example embodiment of third rack assembly 126 combining elements from other example embodiments. Particularly, wire insert 302 may include at least two (2) of a hook 306, or the like, for removably coupling wire insert 302 to wire framework 300. The present example embodiment includes four (4) hooks 306. Wire insert 302 is shown removed from wire framework 300 with respect to the vertical direction V in FIG. 8. A handle 320 may be welded or bent from lower floor portion 316 and extend in the vertical direction, V, such that a user may grasp handle 320 and lift wire insert 302 in the vertical direction V out from wire framework 300.

[0045] Shown in FIG. 9, another example embodiment of third rack assembly 126 may be defined by a wire framework 300. In the present example embodiment, wire framework 300 may include a guide bar 328 across which wire insert 302 translates via hook 306. Wire insert 302 may change position relative to the wire framework 300. As shown in FIG. 9, a first detent 330 may be positioned at an end of guide bar 328 and a second detent 332 may be positioned at an opposite end of guide bar 328. First detent 330 may provide tactile feedback to a user translating wire insert 302 when a gap 324 has been fully opened, e.g., wire insert 302 may be in an open position. First detent 330 may indicate the full justification of wire insert 302 in the open position. Second detent 332 may provide tactile feedback to a user translating wire insert 302 when gap 324 has been fully closed, e.g., wire insert 302 may be in a normal position. Second detent 332 may indicate the full justification of wire insert 302 in the normal position. As shown in FIG. 9, gap 324 is open while wire insert 302 is in the open position. When wire insert 302 is in the normal position, third rack assembly 126 may be closed off from second rack assembly 124, and while wire insert 302 is in the open position, gap 324 of third rack assembly 126 maybe open above second rack assembly 124 in order to fit larger articles for washing.

[0046] FIG. 10 provides an example embodiment of the guide bar 328 of FIG. 9, further including a plurality of detents 400 including first detent 330, detent 334, detent 336, and detent 338 and second detent 332 (not shown in FIG. 10). The plurality of detents 400 may indicate different positions of wire insert 302 and the size of gap 324. Wire rack 302 may be positioned between the plurality of detents 400 in order to clear common items in second rack assembly 124 without unnecessarily sacrificing space of third rack assembly 126. For example, a narrow bottle may not need wire insert 302 translated over as much as a wider bottle such as a tumbler. Thus, guide bar 328 of wire framework 300 may have several set points via the plurality of detents 400, such as set points for wide tumblers, stemware, narrow water bottles, etc.
