The present subject matter relates generally to door assemblies for appliances, and more particularly to lighting assemblies and status indicators mounted within doors of appliances.
Appliances frequently include doors for closing, insulating, concealing, or otherwise providing selective access to cavities or chambers of the appliance. These doors typically include an inner and outer door that are separated by an air gap which may be filled with fiberglass or insulating foam, e.g., for thermal insulation, sound dampening, etc. In order to provide a user with information regarding the appliance operation, e.g., such as a status of an operating cycle or an indication that a cycle is complete, status indicators are often positioned on the outer door of the appliance such that they are visible to a user of the appliance. In addition, or alternatively, appliances such as dishwasher appliance may include control panels that are integrated into the top of the dishwasher door, e.g., to minimize features on the outer door and provide a clean look.
Notably, however, the sleek appearance of top control dishwasher appliances can have drawbacks. For example, the control panel frequently displays an operational status while the dishwasher appliance is operating, and a user can have difficulty viewing the control panel on top control dishwasher appliances when the door is closed and the dishwasher is operating. Thus, it can be difficult for the user to determine the current operational status of top control dishwasher appliances while the door is closed and the control panel is hidden.
Accordingly, an appliance having an improved door and lighting assembly would be useful. More specifically, a door and lighting assembly for an appliance having simplified assembly and improved operational status indicators would be particularly beneficial.
Aspects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.
In one exemplary embodiment, a door assembly for an appliance is provided. The door assembly defines a vertical direction and includes a door frame having a top edge, a user interface board positioned at the top edge of the door frame, a console cover positioned over the user interface board, the console cover having a front surface defining a front indicator extending at least partially along the vertical direction adjacent the top edge of the door frame, and a side-fire light source mounted on the user interface board for selectively emitting light energy toward the front indicator.
In another exemplary embodiment, a dishwasher appliance defining a vertical direction, a lateral direction, and a transverse direction is provided. The dishwasher appliance includes a wash tub positioned within a cabinet and defining a wash chamber and a door assembly pivotally mounted to the cabinet to provide selective access to the wash chamber. The door assembly includes a door frame having a top edge, a user interface board positioned at the top edge of the door frame, a console cover positioned over the user interface board, the console cover having a front surface defining a front indicator extending at least partially along the vertical direction adjacent the top edge of the door frame, and a side-fire light source mounted on the user interface board for selectively emitting light energy toward the front indicator.

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
As illustrated in
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
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
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
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.
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.
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.
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
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.
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
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
Referring now generally to
As best illustrated in
According to exemplary embodiments, inner door panel 216 and outer door panel 218 may be panels that are stamped from stainless steel. Alternatively, inner door panel 216 and outer door panel 218 may be formed from any other suitably rigid material, such as thermoformed plastic, other metals, etc. In general, inner door panel 216 and outer door panel 218 may be assembled in any suitable manner. In addition, inner door panel 216 and outer door panel 218 may be secured together using any suitable mechanical fastener, welding, snap-fit mechanisms, etc. In addition, it should be appreciated that an insulating material (not shown), such as fiberglass or foam insulation, may be positioned within interior chamber 214 to provide thermal and/or sound insulation to dishwashing appliance 100.
Referring again to
Console cover 232 is also positioned on door 106 such that a user can engage, e.g., touch, console cover 232. Thus, the user can activate/deactivate various cycles of dishwasher appliance 100 using console cover 232. In particular, dishwasher appliance 100 includes a user interface board 234, which may be a printed circuit board that is positioned within door frame 212, e.g., on top of console bracket 230. User interface board 234 may include or be operably coupled to one or more user inputs of touch buttons 236 (e.g., or user inputs 166) for receiving user input, providing user notifications, or illuminating to indicate cycle or operating status.
Specifically, according to the embodiment illustrated in
As best shown in
As best shown in
In addition, console cover 232 have any suitable size and shape to facilitate the desired illumination and user interaction features. For example, as shown in
Door assembly 200 may further include a plurality of light sources or lighting devices that are configured for illuminating one or more surfaces of console cover 232. These lighting sources are identified herein generally by reference numeral 260. It should be appreciated that light sources 260 may include any suitable number, type, configuration, and orientation of light sources mounted at any suitable location to illuminate status indicators or buttons in any suitable colors, sizes, patterns, etc. In other words, light sources 260 may be provided as any suitable number, type, position, and configuration of electrical light source(s), using any suitable light technology and illuminating in any suitable color. For example, according to the illustrated embodiment, light sources 260 may include one or more light emitting diodes (LEDs), which may each illuminate in a single color (e.g., white LEDs), or which may each illuminate in multiple colors (e.g., multi-color or RGB LEDs) depending on the control signal from controller 160.
However, it should be appreciated that according to alternative embodiments, light sources 260 may include any other suitable traditional light bulbs or sources, such as halogen bulbs, fluorescent bulbs, incandescent bulbs, glow bars, a fiber light source, etc. Moreover, light sources 260 may be operably coupled (e.g., electrically coupled) to user interface board 234, another suitable control board, and/or controller 160 (
Specifically, as best illustrated in
Specifically, according to the illustrated embodiment, light sources 260 of door assembly 200 include one or more orthogonal light emitting devices, referred to herein as side-fire light sources 264. As shown, side fire light sources 264 may be mounted on user interface board 234 and are generally configured for directing a beam of light energy (e.g., referred to herein by reference numeral 266) substantially within a horizontal plane (e.g., as identified by the transverse direction T and/or the lateral direction L). Thus, according to the illustrated embodiment, side fire light sources 264 and front indicator 244 are located in a single horizontal plane. In addition, console cover 232 may define a pocket 268 sized for receiving side fire light sources 264 (or multiple pockets 268 for receiving vertical light sources 262). In this manner, side fire light sources 264 may be mounted on top of user interface board 234 while permitting a flush mount of console cover 232 at top edge 202 of door frame 212.
As best shown in
As shown, both vertical light sources 262 and side fire light sources 264 may be mounted to user interface board 234. In addition, vertical light sources 262 may be oriented for vertical illumination to illuminate touch buttons 236 while side fire light sources 264 are oriented to illuminate front indicator 244. In particular, side fire light sources 264 are operable to direct light beam 266 from within door assembly 200 towards and/or through front indicator 244 substantially along the transverse direction T. Although side fire light sources 264 are illustrated as illuminating front indicator 244, it should be appreciated that in alternative example embodiments, these lighting devices can be any suitable device for emitting light beam 266, e.g., such that light beam 266 is substantially perpendicular to a line that is normal to top edge 202 of door frame 212. For example, these light sources can be top-view LEDs or reverse-mount LEDs with light redirecting devices, such as reflectors, lenses, or fiber optic cables, that redirect light beam 266.
Generally, console cover 232 may be any suitable transparent or semitransparent feature for diffusing, directing, or otherwise transmitting light from a light source, as described in more detail below. For example, console cover 232 may be formed from a suitable transparent or translucent material configured to direct light energy, such as a dielectric material, such as glass or plastic, polycarbonate, polypropylene, polyacrylic, or any other suitable material.
According to exemplary embodiments the present subject matter, console cover 232 may be a dead fronted panel. As used herein, the term “dead front” and the like is generally intended to refer to portions of a control panel which may be used as indicators, buttons, interactive control surfaces, or other user-interaction features without exposing the user to the operating side of the equipment or live parts and connections, i.e., lights, electrical connections, etc. For example, console cover 232 may include a transparent or translucent body 270 and an opaque masking material 272 that is selectively printed on top surface 240 and front surface 242 of translucent body 270 to define touch buttons 236, front indicator 244, and/or other illuminated features on console cover 232. Thus, the dead fronted top surface 240 in front surface 242 may be the surfaces that are contacted for controlling dishwasher appliance 100 or which may be illuminated for purposes of indicating operating status or other conditions to the user of the dishwasher appliance 100, e.g., particularly when door assembly 200 is in the closed position. Notably, when light sources 260 associated with particular touch buttons 236 or front indicator 244 are deactivated, these features may match the color of opaque material 272 such that these illumination features of are not visible or difficult to differentiate from the rest of console cover 232.
Opaque material 272 may be deposited on translucent body 270 to define any suitable number, size, and configuration of illuminated features. These illuminated features may be shapes or include other forms such as symbols, words, etc. that are visible on console cover 232. More specifically, when vertical light sources 262 are energized, touch buttons 236 on top surface 240 may be illuminated. When side fire light sources 264 are energized, front indicator 244 on front surface 242 may be eliminated.
Although door assembly 200 is described herein as including a single side fire light source 264, it should be appreciated that door assembly 200 could include any suitable number, type, and position of side fire light sources 264. In this regard, console cover 232 and/or front indicator 244 may extend an entire width of door assembly 200 along the lateral direction L. Thus, front surface 242 may be visible along the entire width of door assembly 200 and may be used to indicate different operational statuses, the progress of cycles, etc. Therefore, front indicator 244 may include a plurality of different illumination regions, e.g., as defined by masking material or opaque material 272. Alternatively, the entire width of the front surface 242 may be void of opaque material 272 to define one elongated front indicator 244.
For example, according to one exemplary embodiment, a plurality of side fire light sources 264 may be spaced apart along the lateral direction L and may be selectively illuminated to form a cycle progress bar. In this regard, as the cycle commences side fire light sources 264 may be progressively illuminated starting at a first lateral end 210 of door assembly 200 (e.g., the left side) and moving toward a second lateral end 210 of door assembly 200 (e.g., the right side). It should be appreciated that the illumination patterns and light source configurations described herein are only exemplary and are not intended to limit the scope of the present subject matter in any manner.
