DETAILED DESCRIPTION
[0018] 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.
[0019] As used herein, the term or is generally intended to be inclusive (i.e., A or B is intended to mean A or B or both). Furthermore, as used herein, terms of approximation, such as approximately or substantially, refer to being within a ten percent margin of error.

[0021] The tub 104 includes a front opening 114 and a door 116 hinged at its bottom for movement between a normally closed vertical position (shown in
[0022] As illustrated in
[0023] Some or all of the rack assemblies 122, 124, 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, 124, 126 are shown in
[0024] Dishwasher 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
[0025] 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 or wash fluid (e.g., detergent, water, 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 or wash fluid from pump 152 to the various spray assemblies and manifolds. For example, as illustrated in
[0026] As illustrated, primary supply conduit 154 is used to supply wash fluid to one or more spray assemblies (e.g., to mid-level spray arm assembly 140 and upper spray assembly 142). 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. For example, according to another exemplary embodiment, primary supply conduit 154 could be used to provide wash fluid to mid-level spray arm assembly 140 and a dedicated secondary supply conduit (not shown) could be utilized to provide wash fluid to upper spray assembly 142. Other plumbing configurations may be used for providing wash fluid to the various spray devices and manifolds at any location within dishwasher appliance 100.
[0027] Each spray arm assembly 134, 140, 142, integral spray manifold 144, 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 arm 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. The resultant movement of the spray arm assemblies 134, 140, 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 example, dishwasher 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.
[0028] In operation, pump 152 draws wash fluid in from sump 138 and pumps it to a diverter assembly 156 (e.g., which may be positioned within sump 138 of dishwasher appliance 100). Diverter assembly 156 may include a diverter disk (not shown) disposed within a diverter chamber 158 for selectively distributing the wash fluid to the spray arm assemblies 134, 140, 142 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 158. In this manner, the diverter disk may be selectively rotated to provide wash fluid to the desired spray device.
[0029] According to an exemplary 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 are illustrated in
[0030] The dishwasher 100 is further equipped with a controller 160 to regulate operation of the dishwasher 100. The 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 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.
[0031] The controller 160 may be positioned in a variety of locations throughout dishwasher 100. In the illustrated embodiment, the controller 160 may be located within a control panel area 162 of door 116, as shown in
[0032] It should be appreciated that the invention is not limited to any particular style, model, or configuration of dishwasher 100. The exemplary embodiment depicted in
[0033] Turning now generally to
[0034] As shown, the door may include one or more exterior panels formed about and defining an interior chamber 234 of the door. For instance, a forward door panel 230 may be positioned at or proximal to the front end 220 (i.e., distal to the rear end 222). A top panel 232 may be positioned on or otherwise attached to forward door panel 230 at the top end 216 of the door. For instance, top panel 232 may extend rearward from forward door panel 230 along the transverse direction T. In certain embodiments, top panel 232 is positioned perpendicular (i.e., at substantially 90 relative to) forward door panel 230. As should be understood, in some embodiments, forward door panel 230 covers substantially all of the door along the vertical direction V and generally extend from the top end 216 to the bottom end 218 (
[0035] In some embodiments, top panel 232 includes or is provided as a capacitive interface panel 236 (e.g., as part of user interface 164
[0036] Generally, a light source 242 is positioned within interior chamber 234 to provide light (e.g., light emissions 246) to illuminate an indicator lens 244 that may be visible to a user outside of interior chamber 234. As should be understood, the light source 242 and indicator lens 244 may generally correspond to a single indicator light (e.g., a display component 168
[0037] As shown in
[0038] In some embodiments, light source 242 is directed substantially downward along the vertical direction V. Thus, when activated to illuminate indicator lens 244, light source 242 may project light emissions 246 along the vertical direction V and generally toward the bottom end 218 (
[0039] Generally, indicator lens 244 may be formed from a suitable transparent or translucent material configured to direct light emissions 246 therethrough (e.g., glass, polycarbonate, acrylic, etc.). When assembled, indicator lens 244 spaced apart from light source 242 along the vertical direction V. In particular, at least a portion of indicator lens 244 is positioned below light source 242. Indicator lens 244 itself may extend from a receiving surface 248 to projection surface 250 that is nonparallel (e.g., perpendicular or set in another suitable angle between 0 and)180 relative to receiving surface 248. Receiving surface 248 may face light source 242 (e.g., from a position above light source 242) to receive a light emission 246 therefrom. A projection path 252 for light emissions 246 may be defined through indicator lens 244 from receiving surface 248 to projection surface 250. Thus, at least a portion of the light emission 246 received at receiving surface 248 may be directed to projection surface 250 and then, for example, to a user facing the door.
[0040] An indicator aperture 254 is defined through forward door panel 230. As shown, indicator aperture 254 may extend along the transverse direction T to permit light emissions 246 therethrough. For instance, indicator aperture 254 may be defined as a void extending fully through forward door panel 230 (e.g., completely through forward door panel 230 along the transverse direction T). In some such embodiments, at least a portion of indicator lens 244 (e.g., projection surface 250) is received through indicator aperture 254. In alternative embodiments, however, indicator aperture 254 is defined as a nonpermeable (e.g., to water) segment of forward door panel 230 through which light emissions 246 may pass. As an example, indicator aperture 254 may be a transparent or translucent portion of forward door panel 230 that generally permits at least a portion of visible light therethrough (e.g., from interior chamber 234 to the ambient environment surrounding the door). When light source 242 is activated or illuminated, light emissions 246 from light source 242 may thus be directed along projection path 252 from receiving surface 248 and through indicator aperture 254. Advantageously, the relative position of light source 242, indicator lens 244, and indicator aperture 254 may permit a significant amount light to be directed through interior chamber 234 along the projection path 252 and reduce the overall transverse depth that may be required for interior chamber 234. Moreover, the described embodiments may permit light source 242 to be mounted on control board 240, further reducing complexity and space requirements within the door.
[0041] In some embodiments, one or both of receiving surface 248 and projection surface 250 define a corresponding noncircular surface area. As an example, receiving surface 248 may have a transverse receiving length 256 and a lateral receiving width 258 defining a noncircular surface area of receiving surface 248 (e.g., below light source 242). Projection surface 250 may have a vertical projection height 260 and a lateral projection width 262 defining a noncircular surface area of projection surface 250 (e.g., in front of or forward from light source 242 and receiving surface 248). In certain embodiments, the noncircular surface area defined by projection surface 250 is greater than the noncircular surface area defined by receiving surface 248. In other words, the surface area magnitude and dimensions of projection surface 250 may be larger than those of receiving surface 248. Advantageously, the noncircular surface area defined by projection surface 250 may be more easily viewed (and thereby understood) than typical visual indicator lights (e.g., having a relatively small or circular shape).
[0042] Exemplary embodiments include an internal bracket 264 mounted within interior chamber 234. Thus, an internal bracket 264 may be positioned behind forward door panel 230 along the transverse direction T or below top panel 232 along the vertical direction V. In optional embodiments, internal bracket 264 is fixed within interior chamber 234 (e.g., mounted to an inner door or inner framenot pictured). In some embodiments, light source 242 is supported on or above internal bracket 264. As an example, light source 242 may be attached to control board 232 above internal bracket 264. Optionally, control board 232 and light source 242 may be attached to internal bracket 264. In certain embodiments, light source 242 is positioned above receiving surface 248 (e.g., along the vertical direction V) and at least a portion of internal bracket 264. In additional or alternative embodiments, internal bracket 264 defines a light channel 266 extending therethrough. In particular, light channel 266 may extend along the vertical direction V (e.g., generally along the vertical direction V such that one opening of the light channel 266 is positioned below the other opening of the light channel 266) between light source 242 and receiving surface 248.

[0047] In some such embodiments, forward door panel 230 is generally open to the ambient environment and defines an outermost or exterior surface 272 (e.g., such that a user may touch or contact the door at exterior surface 272 defined by forward door panel 230). For instance, projection surface 250 may be framed by or positioned within indicator aperture 254. Optionally, projection surface 250 may be in flushed vertical alignment with an exterior surface 272 defined by forward door panel 230, as illustrated in
