Description

FIELD

[0001] The present subject matter relates generally to dishwashing appliances or, more specifically, to dishwashing appliance tub trim locating features.BACKGROUND

[0002] Dishwashing appliances generally include a tub that defines a wash chamber. Rack assemblies can be mounted within the wash chamber of the tub for receipt of articles for washing. Multiple spray assemblies can be positioned within the wash chamber for applying or directing wash liquid (e.g., water, detergent, etc.) towards articles disposed within the rack assemblies in order to clean such articles. Dishwashing appliances are also typically equipped with one or more pumps, such as a circulation pump or a drain pump, for directing or motivating wash liquid from the sump to, e.g., the spray assemblies or an area outside of the dishwashing appliance.

[0003] Tub trim is commonly used to protect components of dishwashing appliances exposed to the operator, such as metal collar edges, and / or may acoustically isolate the interior of dishwashing appliances to reduce noise created by dishwashing appliances, such as during a cycle. The tub trim is typically installed either prior to shipping, such as in a manufacturing or assembly factory, or after shipping, such as in a home by a dishwashing appliance installation technician. However, the tub trim is often difficult to position / locate and attach to dishwashing appliances.

[0004] Accordingly, features for providing improved positioning / locating and attachment of the tub trim to a dishwashing appliance would be useful.BRIEF DESCRIPTION

For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0029] Turning now to the figures, FIGS. 1 through 3 depict an exemplary dishwasher or dishwashing appliance (e.g., dishwasher 100) that may be configured in accordance with aspects of the present disclosure. Generally, dishwasher 100 defines a vertical direction V, a lateral direction L, and a transverse direction T. Each of the vertical direction V, lateral direction L, and transverse direction T are mutually perpendicular to one another and form an orthogonal direction system.

[0030] Dishwasher 100 includes a tub 104 that defines a wash chamber 106 therein. As shown in FIG. 3, tub 104 extends between a top 107 and a bottom 108 along the vertical direction V, between a pair of side walls 110 along the lateral direction L, and between a front side 111 and a rear side 112 along the transverse direction T.

[0031] Tub 104 includes a front opening 114 at the front side 111. In some embodiments, the dishwasher 100 may also include a door 116 at the front opening 114. The door 116 may, for example, be coupled to the tub 104 by a hinge (not shown) at its bottom for movement between a normally closed vertical position (FIGS. 1 and 3), wherein the wash chamber 106 is sealed shut for washing operation, and a horizontal or fully open position (not shown) for loading and unloading of articles from dishwasher 100. A door closure mechanism or assembly 118, e.g., a latch, may be provided to lock and unlock door 116 for accessing and sealing wash chamber 106.

[0032] In exemplary embodiments, side walls 110 accommodate a plurality of rack assemblies. For instance, guide rails 120 may be mounted to side walls 110 for supporting a lower rack assembly 122 and an upper rack assembly 126. In some such embodiments, upper rack assembly 126 is positioned at a top portion of wash chamber 106 above lower rack assembly 122 along the vertical direction V.

[0033] Generally, each rack assembly 122, 126 may be adapted for movement 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 through 3) in which the rack is located inside the wash chamber 106. In some embodiments, movement is facilitated, for instance, by rollers 128 mounted onto rack assemblies 122, 126, respectively.

[0034] Although guide rails 120 and rollers 128 are illustrated herein as facilitating movement of the respective rack assemblies 122, 126, it should be appreciated that any suitable sliding mechanism or member may be used according to alternative embodiments.

[0035] In optional embodiments, some or all of the rack assemblies 122, 126 are fabricated into lattice structures including a plurality of wires or elongated members 130 (for clarity of illustration, not all elongated members making up rack assemblies 122, 126 are shown). In this regard, rack assemblies 122, 126 are generally configured for supporting articles within wash chamber 106 while allowing a flow of wash liquid to reach and impinge on those articles (e.g., during a cleaning or rinsing phase of the wash cycle). According to additional or alternative embodiments, a silverware basket (not shown) may be removably attached to a rack assembly (e.g., lower rack assembly 122), for placement of silverware, utensils, and the like, which are otherwise too small to be accommodated by the rack assembly.

[0036] Generally, dishwasher 100 includes one or more spray assemblies for urging a flow of fluid (e.g., wash liquid) onto the articles placed within wash chamber 106.

[0037] In exemplary embodiments, dishwasher 100 includes a lower spray 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. In this regard, lower spray assembly 134 may generally be configured for urging a flow of wash liquid up through lower rack assembly 122.

[0038] In some embodiments, an upper spray assembly 142 may be located proximate to and, e.g., below, upper rack assembly 126 along the vertical direction V. In this manner, upper spray assembly 142 may be generally configured for urging of wash liquid up through upper rack assembly 126.

[0039] The various spray assemblies and manifolds described herein may be part of a fluid distribution system or fluid circulation assembly 150 for circulating wash liquid in tub 104. In certain embodiments, fluid circulation assembly 150 includes a circulation pump 152 for circulating wash liquid in tub 104. Circulation pump 152 may be mounted to sump 138 and in fluid communication with the sump 138 through a circulation outlet 151 from the sump 138.

[0040] When assembled, circulation pump 152 may be in fluid communication with an external water supply line (not shown) and sump 138. A water inlet valve (not shown) can be positioned between the external water supply line and circulation pump 152 (e.g., to selectively allow water to flow from the external water supply line to circulation pump 152). Additionally, or alternatively, the water inlet valve can be positioned between the external water supply line and sump 138 (e.g., to selectively allow water to flow from the external water supply line to sump 138). During use, the water inlet valve may be selectively controlled to open to allow the flow of water into dishwasher 100 and may be selectively controlled to close and thereby cease the flow of water into dishwasher 100. Further, fluid circulation assembly 150 may include one or more fluid conduits or circulation piping for directing wash fluid from circulation pump 152 to the various spray assemblies and manifolds. In exemplary embodiments, such as that shown in FIG. 3, a primary supply conduit 154 extends from circulation pump 152, along rear side 112 of tub 104 along the vertical direction V to supply wash liquid throughout wash chamber 106.

[0041] In optional embodiments, circulation pump 152 urges or pumps wash liquid to a diverter 156 (FIG. 3). In some such embodiments, diverter 156 is positioned within sump 138 of dishwasher 100). Diverter 156 may include a diverter disk (not shown) disposed within a diverter chamber 158 for selectively distributing the wash liquid to the spray assemblies 134, 142, or other spray manifolds or assemblies. For instance, the diverter disk may have at least one aperture configured to align with one or more outlet ports (not shown) at the top of diverter chamber 158. In this manner, the diverter disk may be selectively rotated to provide wash liquid to the desired spray device(s).

[0042] In exemplary embodiments, diverter 156 is configured for selectively distributing the flow of wash liquid from circulation pump 152 to various fluid supply conduits—only some of which are illustrated in FIG. 3 for clarity. In certain embodiments, diverter 156 includes two or more outlet ports (not shown) for supplying wash liquid to a first conduit for rotating lower spray assembly 134 and a second conduit for supplying upper spray assembly 142 (e.g., primary supply conduit 154). Additional embodiments may also include one or more additional conduits, e.g., a third conduit for spraying an auxiliary rack such as a silverware rack, etc.

[0043] In some embodiments, a primary supply conduit 154 is used to supply wash liquid to one or more spray assemblies (e.g., to upper spray assembly 142). It should be appreciated, however, that according to alternative embodiments, any other suitable plumbing configuration may be used to supply wash liquid throughout the various spray manifolds and assemblies described herein. For instance, according to another exemplary embodiment, primary supply conduit 154 could be used to provide wash liquid to lower spray assembly 134 and a dedicated secondary supply conduit (not shown) could be utilized to provide wash liquid to upper spray assembly 142. Other plumbing configurations may be used for providing wash liquid to the various spray devices and manifolds at any location within dishwasher 100.

[0044] Each spray assembly 134 and 142, or other spray device as may be included in dishwasher 100, may include an arrangement of discharge ports or orifices for directing wash liquid received from circulation 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 liquid flowing through the discharge ports. Alternatively, spray assemblies 134, 142 may be motor-driven, or may operate using any other suitable drive mechanism. Spray manifolds and assemblies may also be stationary. The resultant movement of the spray assemblies 134, 142 and the spray from fixed manifolds provides coverage of dishes and other dishwasher contents with a washing spray. Other configurations of spray assemblies may be used as well. For instance, dishwasher 100 may have additional spray assemblies for cleaning silverware, for scouring casserole dishes, for spraying pots and pans, for cleaning bottles, etc.

[0045] Drainage of soiled wash liquid within sump 138 may be provided, for instance, by a drain pump 168 (e.g., during or as part of a drain phase). In particular, wash liquid may exit sump 138 through a drain outlet 167 and may flow through a drain conduit or directly to the drain pump 168. Thus, drain pump 168 is downstream of sump 138 and facilitates drainage of the soiled wash liquid by urging or pumping the wash liquid to a drain line external to dishwasher 100.

[0046] In some embodiments, a filter assembly may be provided, e.g., in the sump 138 and / or at a top entrance into the sump 138, e.g., to filter fluid to fluid circulation assembly 150 and / or drain pump 168. Generally, the filter assembly removes soiled particles from the liquid that flows to the sump 138 from the wash chamber 106 during operation of dishwasher 100. In exemplary embodiments, the filter assembly may include both a first filter (also referred to as a “coarse filter”) and a second filter (also referred to as a “fine filter”).

[0047] Although a separate circulation pump 152 and drain pump 168 are described herein, it is understood that other suitable pump configurations (e.g., using only a single pump for both recirculation and draining) may be provided.

[0048] The dishwasher 100 may further include a heating element 184, such as a resistance heating element, positioned in or near the sump 138. For example, the heating element 184 may be positioned “near” the sump 138 in that the heating element 184 is disposed above the sump 138 and within the lower region 136 of wash chamber 106, such as below the lower spray assembly 134 and / or below the lower rack assembly 122. The heating element 184 may be positioned and configured to heat liquid in the sump 138, such as for a heated wash phase, and / or to heat air within the wash chamber 106, such as for drying articles during a dry phase.

[0049] Dishwasher 100 may also include ventilation features, e.g., to promote improved, e.g., more rapid, drying of articles therein after the wash and rinse phases. For example, one or more vents 170 may be provided in the tub 104 for introducing relatively dry air from outside of the tub 104 into the wash chamber 106 and / or for removing relatively humid air from the wash chamber 106 to the outside of the tub 104. In some embodiments, a fan 172 may be provided. The fan 172 may be operable to urge air through the wash chamber 106, such as to promote air circulation and / or ventilation within and through the wash chamber 106. Such air movement may increase the rate of evaporation of moisture from articles in the wash chamber 106 after a wash and / or rinse phase.

[0050] In certain embodiments, dishwasher 100 includes a controller 160 configured to regulate operation of dishwasher 100 (e.g., initiate one or more wash operations). 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 wash operation or wash cycle that may include a pre-wash phase, a wash phase, a rinse phase, a drain phase, and / or a dry phase. The memory may represent random access memory such as DRAM, or read only memory such as ROM or FLASH. In some embodiments, 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 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. It should be noted that controllers as disclosed herein are capable of and may be operable to perform any methods and associated method steps as disclosed herein.

[0051] Controller 160 may be positioned in a variety of locations throughout dishwasher 100. In optional embodiments, controller 160 is located within a control panel area 162 of door 116 (e.g., as shown in FIG. 1 or FIG. 2). Input / output (“I / O”) signals may be routed between the control system and various operational components of dishwasher 100 along wiring harnesses that may be routed through the bottom of door 116. Typically, the controller 160 includes or is operatively coupled to a user interface / controls 164 through which a user may select various operational features and modes and monitor progress of dishwasher 100. In some embodiments, user interface 164 includes a general purpose I / O (“GPIO”) device or functional block. In additional or alternative embodiments, user interface 164 includes 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. In further additional or alternative embodiments, user interface 164 includes a display component, such as a digital or analog display device designed to provide operational feedback to a user. When assembled, user interface 164 may be in operative communication with the controller 160 via one or more signal lines or shared communication busses.

[0052] It should be appreciated that the invention is not limited to any particular style, model, or configuration of dishwasher 100. The exemplary embodiments depicted in FIGS. 1 through 3 are for illustrative purposes only. For instance, different locations may be provided for control panel area 162 (e.g., on the front of the door 116 as illustrated in FIG. 1 or on the top of the door 116 as illustrated in FIG. 2, or other locations as well), different configurations may be provided for rack assemblies 122, 126, different spray assemblies 134, 142 and spray manifold configurations may be used, different sensors may be used, and other differences may be applied while remaining within the scope of the present disclosure.

[0053] Referring now generally to FIGS. 4 through 14, a collar 200 and a tub trim 202 of dishwasher 100 will be described according to example embodiments of the present subject matter. In particular, various locating and fastening features of the collar 200 and the tub trim 202 will be described herein. The locating and fastening features described may facilitate attachment and removal of the tub trim 202 to the collar 200. Although exemplary constructions of the collar 200 and the tub trim 202 are described herein, it should be appreciated that variations and modifications may be made to the collar 200 and the tub trim 202 while remaining within the scope of the present subject matter.

[0054] According to some example embodiments, the front side 111 of the tub 104 may include a plurality of boundary surfaces that surround an opening 201 to the wash chamber 106. For example, the front side 111 of the tub 104 may include a pair of opposing lateral sides, such as a first or left-side boundary surface 204 and a second or right-side boundary surface 206. The front side 111 of the tub 104 may also include a third or top side boundary surface 208. The left-side boundary surface 204 may extend approximately in the vertical direction V downward from a left-side 210 of the top side boundary surface 208. Likewise, the right-side boundary surface 206 may extend approximately in the vertical direction V downward from a right-side 212 of the top side boundary surface 208. As such, the left-side boundary surface 204 and the right-side boundary surface 206 may be spaced apart from each other in the lateral direction L, the opening 201 to the wash chamber 106 spanning between the left-side boundary surface 204 and the right-side boundary surface 206. Furthermore, the top side boundary surface 208 may extend along the top 107 of the tub 104 approximately in the lateral direction L.

[0055] According to some example embodiments, the collar 200 may include one or more collar segments 213. For example, as described herein, the collar segments 213 include a first or left-side collar segment 214 (FIG. 4), a second or right-side collar segment 216 (FIG. 4), and a third or top side collar segment 218 (FIG. 4). Generally, as best illustrated in FIG. 5, each collar segment 213 defines a length l, a width w, and a depth d. Each of the length l, width w, and depth d are mutually perpendicular to one another. The collar segments 213 may be connected together. For example, the left-side collar segment 214 may be connected to, e.g., fastened to, and extend approximately in the vertical direction V downward from a left-side of the top side collar segment 218 and, thus, approximately parallel to the left-side boundary surface 204. Likewise, the right-side collar segment 216 may be connected to, e.g., fastened to, and extend approximately in the vertical direction V downward from a right-side of the top side collar segment 218 and, thus, approximately parallel to the right-side boundary surface 206. As such, the left-side collar segment 214 and the right-side collar segment 216 may be spaced apart from each other in the lateral direction L. Furthermore, the top side collar segment 218 may extend along the top 107 of the tub 104 approximately in the lateral direction L and, thus, approximately parallel to the top side boundary surface 208.

[0056] According to some example embodiments, the collar 200 of the dishwasher 100 and, thus, each collar segment 213 of the collar 200, is positioned outside of the wash chamber 106 along a different side of the exterior of the tub 104 of the dishwasher 100. For example, the top side collar segment 218 may be positioned on the top 107 of the tub 104.

[0057] According to example embodiments and, as best illustrated in FIG. 5, each collar segment 213 includes a main collar body 230 having a base plate 232. The base plate 232 may include a central brace 234. As illustrated, a pair of central brace locating tabs 231 may extend from the central brace 234 and bend away from the central brace 234, e.g., at approximately 90 degrees. The pair of central brace locating tabs 231 may be utilized to position and / or attach the collar segment 213 to the tub 104 of the dishwasher 100, such as by the central brace locating tabs 231 each being received within a corresponding notch (not shown) on the tub 104.

[0058] Furthermore, the base plate 232 may include one or more wings extending from the central brace 234. For example, as illustrated in FIG. 5, the base plate 232 may include a first wing 236 extending from a first side 233 of the central brace 234 and a second wing 238 extending from a second side 235 of the central brace 234. As illustrated, the first wing 236 and the second wing 238 may be axially aligned along an axis A extending approximately parallel to the length l of the collar segment 213. The first wing 236 and the second wing 238 may each include a first side or end 237 and a second side or end 239 that are spaced apart from and approximately parallel to each other. The first end 237 and the second end 239 may define width boundaries of the first wing 236 and the second wing 238.

[0059] Additionally, the main collar body 230 of each collar segment 213 may include one or more flanges 240 protruding from the base plate 232. For example, the main collar body 230 may include a pair of first flanges 242, a first of which extends along the first end 237 of the first wing 236 and a second of which extends along the first end 237 of the second wing 238. Additionally, or alternatively, in some embodiments, the flange(s) 240 may include a pair of second flanges 244, a first of which extends along the second end 239 of the first wing 236 and a second of which extends along the second end 239 of the second wing 238. As illustrated, the pair of first flanges 242 and / or the pair of second flanges 244 may be integrally formed with the base plate 232. Additionally, the pair of first flanges 242 and / or the pair of second flanges 244 may be bent relative to the base plate 232, e.g., at approximately 90-degree angles relative to the base plate 232. In this respect, in some embodiments, the pair of first flanges 242, the pair of second flanges 244, and the base plate 232 may be a C-channel cross-sectional shape. For example, the first wing 236 and the second wing 238 may each be a C-channel cross-sectional shape.

[0060] Furthermore, in some embodiments, a pair of fastening plates 246 may extend from ends of the first wing 236 and the second wing 238. For example, the first wing 236 may be attached to / extend from the central brace 234 at one end, and one of the pair of fastening plates 246 may be attached to / extend from an opposite end. Likewise, the second wing 238 may be attached to / extend from the central brace 234 at one end, and one of the pair of fastening plates 246 may be attached to / extend from an opposite end. The pair of fastening plates may each define a fastener boss 248 therethrough that may align with corresponding fastener bosses (not shown) on the tub 104 when the pair of central brace locating tabs 231 are each received within the corresponding notch (not shown) on the tub 104. Thus, fasteners (not shown) may be received through the fastener bosses 248 within the fastener plates 246 and through the corresponding fastener bosses on the tub 104 to secure the collar segment 213 onto the tub 104.

[0061] According to some example embodiments, each collar segment 213 of the collar 200 may include one or more bridged snap protuberances 250 for attaching the tub trim 202 to the collar segment 213 by snapping a portion of the tub trim 202 into / through the bridged snap protuberance(s) 250. For example, as illustrated in FIG. 5, the collar segment 213 may include two bridged snap protuberances 250, such as lance bridge snaps 250. Each lance bridge snap 250 protrudes from a surface of the main collar body 230. For example, as illustrated in FIG. 5, each of the lance bridge snaps 250 may protrude from a different one of the pair of first flanges 242. Additionally, slots may be defined between the first flanges 242 and the lance bridge snaps 250 for receiving a corresponding component of the tub trim 202 therein for attaching or “snapping” the tub trim 202 to the collar segment 213. The lance bridge snaps 250 may be oriented on the first flanges 242 such that the slots are approximately parallel to the base plate 232. As will be described below, the bridged snap protuberance(s) 250 may be any suitable number of snap protuberances. Furthermore, as will be described below, the bridged snap protuberance(s) 250 may constrain movement of the tub trim 202 relative to the collar segment 213.

[0062] According to some example embodiments, each collar segment 213 may include one or more tub trim locating tabs 260 that may be utilized to position and attach the tub trim 202 on the collar segment 213. For example, as will be described below, the locating tab(s) 260 may be received through one or more corresponding notches defined through the tub trim 202 for positioning and attaching the tub trim 202 on the collar segment 213. As illustrated, the locating tab(s) 260 of each collar segment 213 may extend from a surface of the main collar body 230, such as from one or both of the pair of first flanges 242 and / or from one or both of the pair of second flanges 244, such as directly alongside the base plate 232.

[0063] Moreover, an angle may be defined between each of the locating tabs 260 and the corresponding surface from which the locating tabs 260 extend. For example, in some embodiments, one or more of the locating tabs 260 may extend relative to the corresponding flange 242, 244 from which the locating tab(s) 260 extends such that an angle between 75 degrees and 105 degrees, e.g., approximately 90 degrees, is defined between the locating tab(s) 260 and the corresponding flange 242, 244 from which the locating tab(s) 260 extends.

[0064] In some embodiments, the locating tab(s) 260 may be integrally formed with the flange 242, 244 from which the locating tab(s) 260 extends. As such, the locating tab(s) 260 may be a piece(s) that is bent from the corresponding flange 242, 244 from which the locating tab(s) 260 extends. In this respect, the locating tab(s) 260 may be bent away from the corresponding flange 242, 244 from which the locating tab(s) 260 extend and directly alongside the base plate 232 such that an angle of approximately 90 degrees is defined between the locating tab(s) 260 and the corresponding flange(s) 242, 244 from which the locating tab(s) 260 extends.

[0065] According to some example embodiments, the dishwasher 100 may also include one or more pieces of the tub trim 202, each of which may be positioned and attached on one of the collar segments 213. Each piece of tub trim 202 may be extruded or otherwise formed from a material that permits flexing of the piece of tub trim 202, such as rubber, for ease of installation of the pieces of tub trim 202. The pieces of tub trim 202 may provide an aesthetically desirable look to the dishwasher 100 and seal gaps between the dishwasher 100 and the cavity within the dishwasher 100 is received, e.g., cavity below kitchen counter, thus reducing noise created by the dishwasher 100, such as during a cycle. As best illustrated in FIG. 6, the tub trim 202 may include a tub trim body 203. The tub trim body 203 may define an L-shape. One or more flange pieces 205 may protrude along an edge of the tub trim body 203. Additionally, a notch 207 may be defined between adjacent flange pieces 205. In embodiments in which two or more notches 207 are defined between adjacent flange pieces 205 and two or more locating tabs 260 are included on the collar segment 213 to which the tub trim 202 is positioned and attached on, the notches 207 may be positioned relative to each other, e.g., spaced apart from each other, such that the notches 207 may simultaneously receive a different one of the locating tabs 260 of the collar segment 213 through the notches 207.

[0066] Various embodiments of the collar segments 213 and the tub trim 202 positioned and attached on each embodiment of the collar segments will be described below.

[0067] As illustrated in FIGS. 5, 7, and 8, in some embodiments, one or more of the collar segments 213, such as the top side collar segment 218, includes a single locating tab 260. The locating tab 260 is integrally formed with and is bent from the first flange 242 on the second wing 238 at approximately 90 degrees relative to the first flange 242. The locating tab 260 extends directly alongside the base plate 232 of the top side collar segment 218. As best illustrated in FIG. 7, the locating tab 260 may include a pair of first tab surfaces 261 approximately parallel to one another and spaced apart from each other by a pair of second tab surfaces 262, which are also approximately parallel to one another and spaced apart from each other. The first tab surfaces 261 and the second tab surfaces 262 define a rectangular shaped locating tab 260. Furthermore, each of the first tab surfaces 261 may define a first tab surface width that is greater than a second tab surface width defined by each of the second tab surfaces 262. As illustrated, the locating tab 260 may be bent relative to the first flange 242 such that the first tab surfaces 261 are approximately perpendicular to the base plate 232 and the second tab surfaces 262 are approximately parallel to the base plate 232.

[0068] Furthermore, the top side collar segment 218 includes a lance bridge snap 250 protruding from the same first flange 242 on the second wing 238 as the locating tab 260 described above. The lance bridge snap 250 may be positioned approximately next to or coupled to, such as within 0 to 10 centimeters, such as 1 to 5 centimeters, such as approximately 2 centimeters apart from the locating tab 260. In this respect, an installer or assembler may quickly locate the lance bridge snap 250 upon locating the locating tab 260 due to the proximity of the lance bridge snap 250 and the locating tab 260 to each other.

[0069] Additionally, the tub trim 202 includes a single notch 207 that corresponds to the single locating tab 260 of the top side collar segment 218. As illustrated in FIG. 8, the tub trim 202 is placed over the first flange 242 of the second wing 238 such that the locating tab 260 is received through the notch 207 to position and attach the piece of tub trim 202 on the top side collar segment 218. Receipt of the locating tab 260 through the notch 207 constrains movement of the tub trim 202 relative to the first flange 242 of the second wing 238 and, thus, relative to the top side collar segment 218, in a first direction and a second direction different from the first direction. For example, for the top side collar segment 218, movement of the tub trim 202 may be constrained in both the lateral direction L and in the transverse direction T. Furthermore, the lance bridge snap 250 may constrain movement of the tub trim 202 in a third direction different from the first direction and the second direction, such as in the vertical direction V.

[0070] Additionally, or alternatively, as illustrated in FIGS. 9 and 10, in some embodiments, the single locating tab 260 may be bent relative to the first flange 242 such that the first tab surfaces 261 are approximately parallel to the base plate 232 and the second tab surfaces 262 are approximately perpendicular to the base plate 232. In this respect, the second tab surfaces 262 constrain movement of the tub trim 202 in the first and second directions when received through the notch 207 rather than the first tab surfaces 261.

[0071] Additionally, or alternatively, as illustrated in FIGS. 11 through 14, in some embodiments, one or more of the collar segments 213, such as the top side collar segment 218, the left-side collar segment 214, and / or the right-side collar segment 216, includes a pair of locating tabs 260, such as a first locating tab 263 and a second locating tab 264.

[0072] As best illustrated in FIGS. 11 and 12, in some embodiments, the first and second locating tabs 263, 264 are integrally formed with and are bent from the first flange 242 on the second wing 238 at approximately 90 degrees relative to the first flange 242. The first and second locating tabs 263, 264 extend directly alongside the base plate 232 of the top side collar segment 218. As best illustrated in FIG. 11, the first and second locating tabs 263, 264 may each include the pair of first tab surfaces 261 approximately parallel to one another and spaced apart from each other by the pair of second tab surfaces 262, which are also approximately parallel to one another and spaced apart from each other. The first tab surfaces 261 and the second tab surfaces 262 define rectangular shaped first and second locating tabs 263, 264. Furthermore, each of the first tab surfaces 261 may define the first tab surface width that is greater than the second tab surface width defined by each of the second tab surfaces 262. As illustrated, the first and second locating tabs 263, 264 may be bent relative to the first flange 242 such that the first tab surfaces 261 are approximately perpendicular to the base plate 232 and the second tab surfaces 262 are approximately parallel to the base plate 232. Furthermore, the first and second locating tabs 263, 264 may be spaced apart from each other along the first flange 242 with first tab surfaces 261 of each locating tab 263, 264 facing each other and approximately aligned with each other.

[0073] Moreover, as best illustrated in FIG. 11, in some embodiments, the first and second locating tabs 263, 264 may be positioned on a common side, or a first side, of the lance bridge snap 250. Additionally, a third locating tab 266, which may be parallel, e.g., unbent, relative to the first flange 242, may be positioned between the first and second locating tabs 263, 264.

[0074] Furthermore, the tub trim 202 includes a pair of notches 207, such as a first notch 209 and a second notch 211, that correspond to the first locating tab 263 and the second locating tab 264 of the top side collar segment 218. As illustrated in FIG. 12, the tub trim 202 is placed over the first flange 242 of the second wing 238 such that the first locating tab 263 and the second locating tab 264 are received through the corresponding first notch 209 and second notch 211 respectively to position and attach the piece of tub trim 202 on the top side collar segment 218. Receipt of the first and second locating tabs 263, 264 through the first and second notches 209, 211 constrains movement of the tub trim 202 relative to the first flange 242 of the second wing 238 and, thus, relative to the top side collar segment 218, in the first direction, e.g., the lateral direction L, and the second direction, the transverse direction T.

[0075] Additionally, or alternatively, as illustrated in FIGS. 13 and 14, in some embodiments, the first locating tab 263 may be integrally formed with and bent from the first flange 242 on the second wing 238 at approximately 90 degrees relative to the first flange 242 and the second locating tabs 264 may be integrally formed with and bent from the second flange 244 on the second wing 238 at approximately 90 degrees relative to the second flange 244. The first locating tab 263 and the second locating tab 264 may be axially aligned with each other. For example, the first and second locating tabs 263, 264 may mirror each other, the first locating tab 263 on the first flange 242 and the second locating tab on the second flange 244. In this respect, the left-side collar segment 214 and / or the right-side collar segment 216 may be utilized on the left and right-side boundary surfaces 204, 206 of the front side 111 of the tub 104 without the need for different types of collar segments. As best illustrated in FIG. 14, for the left-side collar segment 214 and / or the right-side collar segment 216, the first or the second locating tab 263, 264 limits movement of the tub trim 202 in the vertical direction V and in the lateral direction L when the first or the second locating tab 263, 264 is received though the notch 207 of the tub trim 202.

FIELD

[0001] The present subject matter relates generally to dishwashing appliances or, more specifically, to dishwashing appliance tub trim locating features.BACKGROUND

[0002] Dishwashing appliances generally include a tub that defines a wash chamber. Rack assemblies can be mounted within the wash chamber of the tub for receipt of articles for washing. Multiple spray assemblies can be positioned within the wash chamber for applying or directing wash liquid (e.g., water, detergent, etc.) towards articles disposed within the rack assemblies in order to clean such articles. Dishwashing appliances are also typically equipped with one or more pumps, such as a circulation pump or a drain pump, for directing or motivating wash liquid from the sump to, e.g., the spray assemblies or an area outside of the dishwashing appliance.

[0003] Tub trim is commonly used to protect components of dishwashing appliances exposed to the operator, such as metal collar edges, and / or may acoustically isolate the interior of dishwashing appliances to reduce noise created by dishwashing appliances, such as during a cycle. The tub trim is typically installed either prior to shipping, such as in a manufacturing or assembly factory, or after shipping, such as in a home by a dishwashing appliance installation technician. However, the tub trim is often difficult to position / locate and attach to dishwashing appliances.

[0004] Accordingly, features for providing improved positioning / locating and attachment of the tub trim to a dishwashing appliance would be useful.BRIEF DESCRIPTION

[0025] Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0026] As used herein, the terms “first,”“second,” and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. The terms “includes” and “including” are intended to be inclusive in a manner similar to the term “comprising.” Similarly, the term “or” is generally intended to be inclusive (i.e., “A or B” is intended to mean “A or B or both”). The term “at least one of” in the context of, e.g., “at least one of A, B, and C” refers to only A, only B, only C, or any combination of A, B, and C. In addition, here and throughout the specification and claims, range limitations may be combined and / or interchanged. Such ranges are identified and include all the sub-ranges contained therein unless context or language indicates otherwise. For example, all ranges disclosed herein are inclusive of the endpoints, and the endpoints are independently combinable with each other. The singular forms “a,”“an,” and “the” include plural references unless the context clearly dictates otherwise.

[0027] Approximating language, as used herein throughout the specification and claims, may be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as “generally,”“about,”“approximately,” and “substantially,” are not to be limited to the precise value specified. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value, or the precision of the methods or machines for constructing or manufacturing the components and / or systems. For example, the approximating language may refer to being within a 10 percent margin, i.e., including values within ten percent greater or less than the stated value. In this regard, for example, when used in the context of an angle or direction, such terms include within ten degrees greater or less than the stated angle or direction, e.g., “generally vertical” includes forming an angle of up to ten degrees in any direction, e.g., clockwise or counterclockwise, with the vertical direction V.

[0028] The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” In addition, references to “an embodiment” or “one embodiment” does not necessarily refer to the same embodiment, although it may. Any implementation described herein as “exemplary” or “an embodiment” is not necessarily to be construed as preferred or advantageous over other implementations. Moreover, each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0029] Turning now to the figures, FIGS. 1 through 3 depict an exemplary dishwasher or dishwashing appliance (e.g., dishwasher 100) that may be configured in accordance with aspects of the present disclosure. Generally, dishwasher 100 defines a vertical direction V, a lateral direction L, and a transverse direction T. Each of the vertical direction V, lateral direction L, and transverse direction T are mutually perpendicular to one another and form an orthogonal direction system.

[0030] Dishwasher 100 includes a tub 104 that defines a wash chamber 106 therein. As shown in FIG. 3, tub 104 extends between a top 107 and a bottom 108 along the vertical direction V, between a pair of side walls 110 along the lateral direction L, and between a front side 111 and a rear side 112 along the transverse direction T.

[0031] Tub 104 includes a front opening 114 at the front side 111. In some embodiments, the dishwasher 100 may also include a door 116 at the front opening 114. The door 116 may, for example, be coupled to the tub 104 by a hinge (not shown) at its bottom for movement between a normally closed vertical position (FIGS. 1 and 3), wherein the wash chamber 106 is sealed shut for washing operation, and a horizontal or fully open position (not shown) for loading and unloading of articles from dishwasher 100. A door closure mechanism or assembly 118, e.g., a latch, may be provided to lock and unlock door 116 for accessing and sealing wash chamber 106.

[0032] In exemplary embodiments, side walls 110 accommodate a plurality of rack assemblies. For instance, guide rails 120 may be mounted to side walls 110 for supporting a lower rack assembly 122 and an upper rack assembly 126. In some such embodiments, upper rack assembly 126 is positioned at a top portion of wash chamber 106 above lower rack assembly 122 along the vertical direction V.

[0033] Generally, each rack assembly 122, 126 may be adapted for movement 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 through 3) in which the rack is located inside the wash chamber 106. In some embodiments, movement is facilitated, for instance, by rollers 128 mounted onto rack assemblies 122, 126, respectively.

[0034] Although guide rails 120 and rollers 128 are illustrated herein as facilitating movement of the respective rack assemblies 122, 126, it should be appreciated that any suitable sliding mechanism or member may be used according to alternative embodiments.

[0035] In optional embodiments, some or all of the rack assemblies 122, 126 are fabricated into lattice structures including a plurality of wires or elongated members 130 (for clarity of illustration, not all elongated members making up rack assemblies 122, 126 are shown). In this regard, rack assemblies 122, 126 are generally configured for supporting articles within wash chamber 106 while allowing a flow of wash liquid to reach and impinge on those articles (e.g., during a cleaning or rinsing phase of the wash cycle). According to additional or alternative embodiments, a silverware basket (not shown) may be removably attached to a rack assembly (e.g., lower rack assembly 122), for placement of silverware, utensils, and the like, which are otherwise too small to be accommodated by the rack assembly.

[0036] Generally, dishwasher 100 includes one or more spray assemblies for urging a flow of fluid (e.g., wash liquid) onto the articles placed within wash chamber 106.

[0037] In exemplary embodiments, dishwasher 100 includes a lower spray 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. In this regard, lower spray assembly 134 may generally be configured for urging a flow of wash liquid up through lower rack assembly 122.

[0038] In some embodiments, an upper spray assembly 142 may be located proximate to and, e.g., below, upper rack assembly 126 along the vertical direction V. In this manner, upper spray assembly 142 may be generally configured for urging of wash liquid up through upper rack assembly 126.

[0039] The various spray assemblies and manifolds described herein may be part of a fluid distribution system or fluid circulation assembly 150 for circulating wash liquid in tub 104. In certain embodiments, fluid circulation assembly 150 includes a circulation pump 152 for circulating wash liquid in tub 104. Circulation pump 152 may be mounted to sump 138 and in fluid communication with the sump 138 through a circulation outlet 151 from the sump 138.

[0040] When assembled, circulation pump 152 may be in fluid communication with an external water supply line (not shown) and sump 138. A water inlet valve (not shown) can be positioned between the external water supply line and circulation pump 152 (e.g., to selectively allow water to flow from the external water supply line to circulation pump 152). Additionally, or alternatively, the water inlet valve can be positioned between the external water supply line and sump 138 (e.g., to selectively allow water to flow from the external water supply line to sump 138). During use, the water inlet valve may be selectively controlled to open to allow the flow of water into dishwasher 100 and may be selectively controlled to close and thereby cease the flow of water into dishwasher 100. Further, fluid circulation assembly 150 may include one or more fluid conduits or circulation piping for directing wash fluid from circulation pump 152 to the various spray assemblies and manifolds. In exemplary embodiments, such as that shown in FIG. 3, a primary supply conduit 154 extends from circulation pump 152, along rear side 112 of tub 104 along the vertical direction V to supply wash liquid throughout wash chamber 106.

[0041] In optional embodiments, circulation pump 152 urges or pumps wash liquid to a diverter 156 (FIG. 3). In some such embodiments, diverter 156 is positioned within sump 138 of dishwasher 100). Diverter 156 may include a diverter disk (not shown) disposed within a diverter chamber 158 for selectively distributing the wash liquid to the spray assemblies 134, 142, or other spray manifolds or assemblies. For instance, the diverter disk may have at least one aperture configured to align with one or more outlet ports (not shown) at the top of diverter chamber 158. In this manner, the diverter disk may be selectively rotated to provide wash liquid to the desired spray device(s).

[0042] In exemplary embodiments, diverter 156 is configured for selectively distributing the flow of wash liquid from circulation pump 152 to various fluid supply conduits—only some of which are illustrated in FIG. 3 for clarity. In certain embodiments, diverter 156 includes two or more outlet ports (not shown) for supplying wash liquid to a first conduit for rotating lower spray assembly 134 and a second conduit for supplying upper spray assembly 142 (e.g., primary supply conduit 154). Additional embodiments may also include one or more additional conduits, e.g., a third conduit for spraying an auxiliary rack such as a silverware rack, etc.

[0043] In some embodiments, a primary supply conduit 154 is used to supply wash liquid to one or more spray assemblies (e.g., to upper spray assembly 142). It should be appreciated, however, that according to alternative embodiments, any other suitable plumbing configuration may be used to supply wash liquid throughout the various spray manifolds and assemblies described herein. For instance, according to another exemplary embodiment, primary supply conduit 154 could be used to provide wash liquid to lower spray assembly 134 and a dedicated secondary supply conduit (not shown) could be utilized to provide wash liquid to upper spray assembly 142. Other plumbing configurations may be used for providing wash liquid to the various spray devices and manifolds at any location within dishwasher 100.

[0044] Each spray assembly 134 and 142, or other spray device as may be included in dishwasher 100, may include an arrangement of discharge ports or orifices for directing wash liquid received from circulation 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 liquid flowing through the discharge ports. Alternatively, spray assemblies 134, 142 may be motor-driven, or may operate using any other suitable drive mechanism. Spray manifolds and assemblies may also be stationary. The resultant movement of the spray assemblies 134, 142 and the spray from fixed manifolds provides coverage of dishes and other dishwasher contents with a washing spray. Other configurations of spray assemblies may be used as well. For instance, dishwasher 100 may have additional spray assemblies for cleaning silverware, for scouring casserole dishes, for spraying pots and pans, for cleaning bottles, etc.

[0045] Drainage of soiled wash liquid within sump 138 may be provided, for instance, by a drain pump 168 (e.g., during or as part of a drain phase). In particular, wash liquid may exit sump 138 through a drain outlet 167 and may flow through a drain conduit or directly to the drain pump 168. Thus, drain pump 168 is downstream of sump 138 and facilitates drainage of the soiled wash liquid by urging or pumping the wash liquid to a drain line external to dishwasher 100.

[0046] In some embodiments, a filter assembly may be provided, e.g., in the sump 138 and / or at a top entrance into the sump 138, e.g., to filter fluid to fluid circulation assembly 150 and / or drain pump 168. Generally, the filter assembly removes soiled particles from the liquid that flows to the sump 138 from the wash chamber 106 during operation of dishwasher 100. In exemplary embodiments, the filter assembly may include both a first filter (also referred to as a “coarse filter”) and a second filter (also referred to as a “fine filter”).

[0047] Although a separate circulation pump 152 and drain pump 168 are described herein, it is understood that other suitable pump configurations (e.g., using only a single pump for both recirculation and draining) may be provided.

[0048] The dishwasher 100 may further include a heating element 184, such as a resistance heating element, positioned in or near the sump 138. For example, the heating element 184 may be positioned “near” the sump 138 in that the heating element 184 is disposed above the sump 138 and within the lower region 136 of wash chamber 106, such as below the lower spray assembly 134 and / or below the lower rack assembly 122. The heating element 184 may be positioned and configured to heat liquid in the sump 138, such as for a heated wash phase, and / or to heat air within the wash chamber 106, such as for drying articles during a dry phase.

[0049] Dishwasher 100 may also include ventilation features, e.g., to promote improved, e.g., more rapid, drying of articles therein after the wash and rinse phases. For example, one or more vents 170 may be provided in the tub 104 for introducing relatively dry air from outside of the tub 104 into the wash chamber 106 and / or for removing relatively humid air from the wash chamber 106 to the outside of the tub 104. In some embodiments, a fan 172 may be provided. The fan 172 may be operable to urge air through the wash chamber 106, such as to promote air circulation and / or ventilation within and through the wash chamber 106. Such air movement may increase the rate of evaporation of moisture from articles in the wash chamber 106 after a wash and / or rinse phase.

[0050] In certain embodiments, dishwasher 100 includes a controller 160 configured to regulate operation of dishwasher 100 (e.g., initiate one or more wash operations). 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 wash operation or wash cycle that may include a pre-wash phase, a wash phase, a rinse phase, a drain phase, and / or a dry phase. The memory may represent random access memory such as DRAM, or read only memory such as ROM or FLASH. In some embodiments, 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 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. It should be noted that controllers as disclosed herein are capable of and may be operable to perform any methods and associated method steps as disclosed herein.

[0051] Controller 160 may be positioned in a variety of locations throughout dishwasher 100. In optional embodiments, controller 160 is located within a control panel area 162 of door 116 (e.g., as shown in FIG. 1 or FIG. 2). Input / output (“I / O”) signals may be routed between the control system and various operational components of dishwasher 100 along wiring harnesses that may be routed through the bottom of door 116. Typically, the controller 160 includes or is operatively coupled to a user interface / controls 164 through which a user may select various operational features and modes and monitor progress of dishwasher 100. In some embodiments, user interface 164 includes a general purpose I / O (“GPIO”) device or functional block. In additional or alternative embodiments, user interface 164 includes 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. In further additional or alternative embodiments, user interface 164 includes a display component, such as a digital or analog display device designed to provide operational feedback to a user. When assembled, user interface 164 may be in operative communication with the controller 160 via one or more signal lines or shared communication busses.

[0052] It should be appreciated that the invention is not limited to any particular style, model, or configuration of dishwasher 100. The exemplary embodiments depicted in FIGS. 1 through 3 are for illustrative purposes only. For instance, different locations may be provided for control panel area 162 (e.g., on the front of the door 116 as illustrated in FIG. 1 or on the top of the door 116 as illustrated in FIG. 2, or other locations as well), different configurations may be provided for rack assemblies 122, 126, different spray assemblies 134, 142 and spray manifold configurations may be used, different sensors may be used, and other differences may be applied while remaining within the scope of the present disclosure.

[0053] Referring now generally to FIGS. 4 through 14, a collar 200 and a tub trim 202 of dishwasher 100 will be described according to example embodiments of the present subject matter. In particular, various locating and fastening features of the collar 200 and the tub trim 202 will be described herein. The locating and fastening features described may facilitate attachment and removal of the tub trim 202 to the collar 200. Although exemplary constructions of the collar 200 and the tub trim 202 are described herein, it should be appreciated that variations and modifications may be made to the collar 200 and the tub trim 202 while remaining within the scope of the present subject matter.

[0054] According to some example embodiments, the front side 111 of the tub 104 may include a plurality of boundary surfaces that surround an opening 201 to the wash chamber 106. For example, the front side 111 of the tub 104 may include a pair of opposing lateral sides, such as a first or left-side boundary surface 204 and a second or right-side boundary surface 206. The front side 111 of the tub 104 may also include a third or top side boundary surface 208. The left-side boundary surface 204 may extend approximately in the vertical direction V downward from a left-side 210 of the top side boundary surface 208. Likewise, the right-side boundary surface 206 may extend approximately in the vertical direction V downward from a right-side 212 of the top side boundary surface 208. As such, the left-side boundary surface 204 and the right-side boundary surface 206 may be spaced apart from each other in the lateral direction L, the opening 201 to the wash chamber 106 spanning between the left-side boundary surface 204 and the right-side boundary surface 206. Furthermore, the top side boundary surface 208 may extend along the top 107 of the tub 104 approximately in the lateral direction L.

[0055] According to some example embodiments, the collar 200 may include one or more collar segments 213. For example, as described herein, the collar segments 213 include a first or left-side collar segment 214 (FIG. 4), a second or right-side collar segment 216 (FIG. 4), and a third or top side collar segment 218 (FIG. 4). Generally, as best illustrated in FIG. 5, each collar segment 213 defines a length l, a width w, and a depth d. Each of the length l, width w, and depth d are mutually perpendicular to one another. The collar segments 213 may be connected together. For example, the left-side collar segment 214 may be connected to, e.g., fastened to, and extend approximately in the vertical direction V downward from a left-side of the top side collar segment 218 and, thus, approximately parallel to the left-side boundary surface 204. Likewise, the right-side collar segment 216 may be connected to, e.g., fastened to, and extend approximately in the vertical direction V downward from a right-side of the top side collar segment 218 and, thus, approximately parallel to the right-side boundary surface 206. As such, the left-side collar segment 214 and the right-side collar segment 216 may be spaced apart from each other in the lateral direction L. Furthermore, the top side collar segment 218 may extend along the top 107 of the tub 104 approximately in the lateral direction L and, thus, approximately parallel to the top side boundary surface 208.

[0056] According to some example embodiments, the collar 200 of the dishwasher 100 and, thus, each collar segment 213 of the collar 200, is positioned outside of the wash chamber 106 along a different side of the exterior of the tub 104 of the dishwasher 100. For example, the top side collar segment 218 may be positioned on the top 107 of the tub 104.

[0057] According to example embodiments and, as best illustrated in FIG. 5, each collar segment 213 includes a main collar body 230 having a base plate 232. The base plate 232 may include a central brace 234. As illustrated, a pair of central brace locating tabs 231 may extend from the central brace 234 and bend away from the central brace 234, e.g., at approximately 90 degrees. The pair of central brace locating tabs 231 may be utilized to position and / or attach the collar segment 213 to the tub 104 of the dishwasher 100, such as by the central brace locating tabs 231 each being received within a corresponding notch (not shown) on the tub 104.

[0058] Furthermore, the base plate 232 may include one or more wings extending from the central brace 234. For example, as illustrated in FIG. 5, the base plate 232 may include a first wing 236 extending from a first side 233 of the central brace 234 and a second wing 238 extending from a second side 235 of the central brace 234. As illustrated, the first wing 236 and the second wing 238 may be axially aligned along an axis A extending approximately parallel to the length l of the collar segment 213. The first wing 236 and the second wing 238 may each include a first side or end 237 and a second side or end 239 that are spaced apart from and approximately parallel to each other. The first end 237 and the second end 239 may define width boundaries of the first wing 236 and the second wing 238.

[0059] Additionally, the main collar body 230 of each collar segment 213 may include one or more flanges 240 protruding from the base plate 232. For example, the main collar body 230 may include a pair of first flanges 242, a first of which extends along the first end 237 of the first wing 236 and a second of which extends along the first end 237 of the second wing 238. Additionally, or alternatively, in some embodiments, the flange(s) 240 may include a pair of second flanges 244, a first of which extends along the second end 239 of the first wing 236 and a second of which extends along the second end 239 of the second wing 238. As illustrated, the pair of first flanges 242 and / or the pair of second flanges 244 may be integrally formed with the base plate 232. Additionally, the pair of first flanges 242 and / or the pair of second flanges 244 may be bent relative to the base plate 232, e.g., at approximately 90-degree angles relative to the base plate 232. In this respect, in some embodiments, the pair of first flanges 242, the pair of second flanges 244, and the base plate 232 may be a C-channel cross-sectional shape. For example, the first wing 236 and the second wing 238 may each be a C-channel cross-sectional shape.

[0060] Furthermore, in some embodiments, a pair of fastening plates 246 may extend from ends of the first wing 236 and the second wing 238. For example, the first wing 236 may be attached to / extend from the central brace 234 at one end, and one of the pair of fastening plates 246 may be attached to / extend from an opposite end. Likewise, the second wing 238 may be attached to / extend from the central brace 234 at one end, and one of the pair of fastening plates 246 may be attached to / extend from an opposite end. The pair of fastening plates may each define a fastener boss 248 therethrough that may align with corresponding fastener bosses (not shown) on the tub 104 when the pair of central brace locating tabs 231 are each received within the corresponding notch (not shown) on the tub 104. Thus, fasteners (not shown) may be received through the fastener bosses 248 within the fastener plates 246 and through the corresponding fastener bosses on the tub 104 to secure the collar segment 213 onto the tub 104.

[0061] According to some example embodiments, each collar segment 213 of the collar 200 may include one or more bridged snap protuberances 250 for attaching the tub trim 202 to the collar segment 213 by snapping a portion of the tub trim 202 into / through the bridged snap protuberance(s) 250. For example, as illustrated in FIG. 5, the collar segment 213 may include two bridged snap protuberances 250, such as lance bridge snaps 250. Each lance bridge snap 250 protrudes from a surface of the main collar body 230. For example, as illustrated in FIG. 5, each of the lance bridge snaps 250 may protrude from a different one of the pair of first flanges 242. Additionally, slots may be defined between the first flanges 242 and the lance bridge snaps 250 for receiving a corresponding component of the tub trim 202 therein for attaching or “snapping” the tub trim 202 to the collar segment 213. The lance bridge snaps 250 may be oriented on the first flanges 242 such that the slots are approximately parallel to the base plate 232. As will be described below, the bridged snap protuberance(s) 250 may be any suitable number of snap protuberances. Furthermore, as will be described below, the bridged snap protuberance(s) 250 may constrain movement of the tub trim 202 relative to the collar segment 213.

[0062] According to some example embodiments, each collar segment 213 may include one or more tub trim locating tabs 260 that may be utilized to position and attach the tub trim 202 on the collar segment 213. For example, as will be described below, the locating tab(s) 260 may be received through one or more corresponding notches defined through the tub trim 202 for positioning and attaching the tub trim 202 on the collar segment 213. As illustrated, the locating tab(s) 260 of each collar segment 213 may extend from a surface of the main collar body 230, such as from one or both of the pair of first flanges 242 and / or from one or both of the pair of second flanges 244, such as directly alongside the base plate 232.

[0063] Moreover, an angle may be defined between each of the locating tabs 260 and the corresponding surface from which the locating tabs 260 extend. For example, in some embodiments, one or more of the locating tabs 260 may extend relative to the corresponding flange 242, 244 from which the locating tab(s) 260 extends such that an angle between 75 degrees and 105 degrees, e.g., approximately 90 degrees, is defined between the locating tab(s) 260 and the corresponding flange 242, 244 from which the locating tab(s) 260 extends.

[0064] In some embodiments, the locating tab(s) 260 may be integrally formed with the flange 242, 244 from which the locating tab(s) 260 extends. As such, the locating tab(s) 260 may be a piece(s) that is bent from the corresponding flange 242, 244 from which the locating tab(s) 260 extends. In this respect, the locating tab(s) 260 may be bent away from the corresponding flange 242, 244 from which the locating tab(s) 260 extend and directly alongside the base plate 232 such that an angle of approximately 90 degrees is defined between the locating tab(s) 260 and the corresponding flange(s) 242, 244 from which the locating tab(s) 260 extends.

[0065] According to some example embodiments, the dishwasher 100 may also include one or more pieces of the tub trim 202, each of which may be positioned and attached on one of the collar segments 213. Each piece of tub trim 202 may be extruded or otherwise formed from a material that permits flexing of the piece of tub trim 202, such as rubber, for ease of installation of the pieces of tub trim 202. The pieces of tub trim 202 may provide an aesthetically desirable look to the dishwasher 100 and seal gaps between the dishwasher 100 and the cavity within the dishwasher 100 is received, e.g., cavity below kitchen counter, thus reducing noise created by the dishwasher 100, such as during a cycle. As best illustrated in FIG. 6, the tub trim 202 may include a tub trim body 203. The tub trim body 203 may define an L-shape. One or more flange pieces 205 may protrude along an edge of the tub trim body 203. Additionally, a notch 207 may be defined between adjacent flange pieces 205. In embodiments in which two or more notches 207 are defined between adjacent flange pieces 205 and two or more locating tabs 260 are included on the collar segment 213 to which the tub trim 202 is positioned and attached on, the notches 207 may be positioned relative to each other, e.g., spaced apart from each other, such that the notches 207 may simultaneously receive a different one of the locating tabs 260 of the collar segment 213 through the notches 207.

[0066] Various embodiments of the collar segments 213 and the tub trim 202 positioned and attached on each embodiment of the collar segments will be described below.

[0067] As illustrated in FIGS. 5, 7, and 8, in some embodiments, one or more of the collar segments 213, such as the top side collar segment 218, includes a single locating tab 260. The locating tab 260 is integrally formed with and is bent from the first flange 242 on the second wing 238 at approximately 90 degrees relative to the first flange 242. The locating tab 260 extends directly alongside the base plate 232 of the top side collar segment 218. As best illustrated in FIG. 7, the locating tab 260 may include a pair of first tab surfaces 261 approximately parallel to one another and spaced apart from each other by a pair of second tab surfaces 262, which are also approximately parallel to one another and spaced apart from each other. The first tab surfaces 261 and the second tab surfaces 262 define a rectangular shaped locating tab 260. Furthermore, each of the first tab surfaces 261 may define a first tab surface width that is greater than a second tab surface width defined by each of the second tab surfaces 262. As illustrated, the locating tab 260 may be bent relative to the first flange 242 such that the first tab surfaces 261 are approximately perpendicular to the base plate 232 and the second tab surfaces 262 are approximately parallel to the base plate 232.

[0068] Furthermore, the top side collar segment 218 includes a lance bridge snap 250 protruding from the same first flange 242 on the second wing 238 as the locating tab 260 described above. The lance bridge snap 250 may be positioned approximately next to or coupled to, such as within 0 to 10 centimeters, such as 1 to 5 centimeters, such as approximately 2 centimeters apart from the locating tab 260. In this respect, an installer or assembler may quickly locate the lance bridge snap 250 upon locating the locating tab 260 due to the proximity of the lance bridge snap 250 and the locating tab 260 to each other.

[0069] Additionally, the tub trim 202 includes a single notch 207 that corresponds to the single locating tab 260 of the top side collar segment 218. As illustrated in FIG. 8, the tub trim 202 is placed over the first flange 242 of the second wing 238 such that the locating tab 260 is received through the notch 207 to position and attach the piece of tub trim 202 on the top side collar segment 218. Receipt of the locating tab 260 through the notch 207 constrains movement of the tub trim 202 relative to the first flange 242 of the second wing 238 and, thus, relative to the top side collar segment 218, in a first direction and a second direction different from the first direction. For example, for the top side collar segment 218, movement of the tub trim 202 may be constrained in both the lateral direction L and in the transverse direction T. Furthermore, the lance bridge snap 250 may constrain movement of the tub trim 202 in a third direction different from the first direction and the second direction, such as in the vertical direction V.

[0070] Additionally, or alternatively, as illustrated in FIGS. 9 and 10, in some embodiments, the single locating tab 260 may be bent relative to the first flange 242 such that the first tab surfaces 261 are approximately parallel to the base plate 232 and the second tab surfaces 262 are approximately perpendicular to the base plate 232. In this respect, the second tab surfaces 262 constrain movement of the tub trim 202 in the first and second directions when received through the notch 207 rather than the first tab surfaces 261.

[0071] Additionally, or alternatively, as illustrated in FIGS. 11 through 14, in some embodiments, one or more of the collar segments 213, such as the top side collar segment 218, the left-side collar segment 214, and / or the right-side collar segment 216, includes a pair of locating tabs 260, such as a first locating tab 263 and a second locating tab 264.

[0072] As best illustrated in FIGS. 11 and 12, in some embodiments, the first and second locating tabs 263, 264 are integrally formed with and are bent from the first flange 242 on the second wing 238 at approximately 90 degrees relative to the first flange 242. The first and second locating tabs 263, 264 extend directly alongside the base plate 232 of the top side collar segment 218. As best illustrated in FIG. 11, the first and second locating tabs 263, 264 may each include the pair of first tab surfaces 261 approximately parallel to one another and spaced apart from each other by the pair of second tab surfaces 262, which are also approximately parallel to one another and spaced apart from each other. The first tab surfaces 261 and the second tab surfaces 262 define rectangular shaped first and second locating tabs 263, 264. Furthermore, each of the first tab surfaces 261 may define the first tab surface width that is greater than the second tab surface width defined by each of the second tab surfaces 262. As illustrated, the first and second locating tabs 263, 264 may be bent relative to the first flange 242 such that the first tab surfaces 261 are approximately perpendicular to the base plate 232 and the second tab surfaces 262 are approximately parallel to the base plate 232. Furthermore, the first and second locating tabs 263, 264 may be spaced apart from each other along the first flange 242 with first tab surfaces 261 of each locating tab 263, 264 facing each other and approximately aligned with each other.

[0073] Moreover, as best illustrated in FIG. 11, in some embodiments, the first and second locating tabs 263, 264 may be positioned on a common side, or a first side, of the lance bridge snap 250. Additionally, a third locating tab 266, which may be parallel, e.g., unbent, relative to the first flange 242, may be positioned between the first and second locating tabs 263, 264.

[0074] Furthermore, the tub trim 202 includes a pair of notches 207, such as a first notch 209 and a second notch 211, that correspond to the first locating tab 263 and the second locating tab 264 of the top side collar segment 218. As illustrated in FIG. 12, the tub trim 202 is placed over the first flange 242 of the second wing 238 such that the first locating tab 263 and the second locating tab 264 are received through the corresponding first notch 209 and second notch 211 respectively to position and attach the piece of tub trim 202 on the top side collar segment 218. Receipt of the first and second locating tabs 263, 264 through the first and second notches 209, 211 constrains movement of the tub trim 202 relative to the first flange 242 of the second wing 238 and, thus, relative to the top side collar segment 218, in the first direction, e.g., the lateral direction L, and the second direction, the transverse direction T.

[0075] Additionally, or alternatively, as illustrated in FIGS. 13 and 14, in some embodiments, the first locating tab 263 may be integrally formed with and bent from the first flange 242 on the second wing 238 at approximately 90 degrees relative to the first flange 242 and the second locating tabs 264 may be integrally formed with and bent from the second flange 244 on the second wing 238 at approximately 90 degrees relative to the second flange 244. The first locating tab 263 and the second locating tab 264 may be axially aligned with each other. For example, the first and second locating tabs 263, 264 may mirror each other, the first locating tab 263 on the first flange 242 and the second locating tab on the second flange 244. In this respect, the left-side collar segment 214 and / or the right-side collar segment 216 may be utilized on the left and right-side boundary surfaces 204, 206 of the front side 111 of the tub 104 without the need for different types of collar segments.
