[0028]
[0029] 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
[0030] As best illustrated in
[0031] 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
[0032] 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
[0033] The various spray assemblies and manifolds described herein may be part of a fluid distribution system or fluid circulation assembly 150 for circulating water and wash fluid in the tub 104. More specifically, fluid circulation assembly 150 includes a pump 152 for circulating water and wash fluid (e.g., detergent, water, 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
[0034] 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.
[0035] 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.
[0036] In operation, pump 152 draws wash fluid in from sump 138 and pumps it to a diverter assembly 156, e.g., which is positioned within sump 138 of dishwasher appliance 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.
[0037] 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
[0038] 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.
[0039] 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
[0040] Controller 160 may be in operative communication with a circuit board 204, located below tub 104 and internal to a modular housing 200. Circuit board 204 may direct electrical signals throughout dishwasher appliance 100 upon receipt of operative directions from controller 160. In some embodiments, circuit board 204 may direct electrical signals to only a part of dishwasher appliance 100, with at least a second circuit board (not shown) directing electrical signals to other elements of dishwasher appliance 100, at the direction of controller 160.
[0041] Dishwasher appliance 100 may also be configured to communicate wirelessly with a cloud-server that may include a database or may be, e.g., a cloud-based data storage system and may also include image recognition and processing capabilities including artificial intelligence as further described below. For example, appliance 100 may communicate with cloud-server over the Internet, and appliance 100 may access via WI-FI®, such as from a WI-FI® access point in a user's home or through a mobile device. Alternatively, dishwasher appliance 100 may be equipped with such image recognition and processing capabilities as part of controller 160 or other components onboard appliance 100.
[0042] While dishwasher 100 is shown, it should be appreciated that the invention is not limited to any particular appliance and could be used in any modular appliance or manufactured part, including washing machines, dryers, refrigerators, ovens, ranges, and any other component having circuitry that requires a housing for circuitry. For example, an apparatus with a bar and a circuit with housing may be provided. The exemplary embodiment depicted in
[0043] For the remainder of the description, and as shown in
[0044] As shown in
[0045] Turning to
[0046] In optional embodiments, modular housing 200 can serve as a protection for circuitry, such as circuit board 204. Thus, compartment body 210 may hold circuitry (e.g., circuit board 204) within compartment volume 206. In other words, compartment body 210, along with compartment door 212 may be designed to house circuity such as circuit board 204. In some embodiments, compartment body 210 houses one or more other portions of appliance 100 that would benefit from a level of protection, such as a controller 160, a camera (not shown), or any other part of appliance 100 that would benefit from being placed in a compartment body 210 of a modular housing 200.
[0047] Modular housing 200 may also attach to a variety of beams, tubes, rails, or places within an appliance, such as dishwasher appliance 100, which may make modular housing 200 useful in a variety of locations within appliance 100. In some embodiments, it may be useful to include more than one modular housing 200 to cover more than one circuitry, if more than one circuitry is included in appliance 100.
[0048] As shown, compartment body 210 defines compartment volume 206. In some embodiments, circuit board 204 is disposed therein (see
[0049] Compartment body 210 includes a bottom section 222 and a set of side sections, (e.g., sections 224, 226, 228). The set of side sections each extend nonparallelly from bottom section 222 (i.e., such that each side section is nonparallel to the bottom section 222). In some embodiments, compartment body 210 includes a first side section 224, a second side section 226, and a third side section 228 in the set of side sections. In certain embodiments, compartment body 210 includes a fourth side section 230 in the set of side sections.
[0050] As shown, compartment body 210 and compartment door 212 may generally form an enclosure with bottom section 222 and side sections 224, 226, 228, 230. For instance, compartment body 210 and compartment door 212 may form a box (e.g., shaped as a rectangular prism). Nonetheless, it is understood that any suitable shape may be provided or formed. Generally, compartment body 210 may be a three-dimensional shape as desired to house components (e.g. circuitry or circuit board 204) of appliance 100 within appliance 100. Optionally, compartment body 210 may connect smoothly or seamlessly from bottom section 222 to side sections 224, 226, 228, or fourth side section 230. In the illustrated embodiments, compartment body 210 forms a corner where bottom section meets each side section 224, 226, 228, 230.
[0051] As shown especially in
[0052] Returning to
[0053] As shown, second side section 226 may extend vertically along a transverse edge of bottom section 222. Second side section 226 may extend laterally outward and roughly perpendicular to bottom section 222. In the illustrated embodiment, second section 226 is also perpendicular to first section 224. Second section is attached to first section 224 as described above. Second section 226 is attached to third section 228 at and a lower vertical edge 236 of second section 226.
[0054] Similarly, third side section 228 may extend transversely along a vertical lower edge of bottom section 222. Third side section 228 may extend laterally outward and roughly perpendicular to bottom section 222 and to second section 226. In the illustrated embodiment, third section 228 is roughly parallel with first section 224. Third section 228 is attached to second section 226 as described above and to fourth section 230 at a lower transverse edge 238.
[0055] Additionally or alternatively, fourth section 230 may extend transversely along a transverse edge of bottom section 222, this transverse edge of bottom section 222 opposite to the transverse edge of bottom section 222 that second section 226 is attached to. Fourth section 230 may extend laterally outward and roughly perpendicular to bottom section 222, first section 224, and third section 228. As shown, fourth section 230 is roughly parallel with second section 226. Fourth section 230 is attached to third section 228 at lower transverse edge 238 and to first section 224 at transverse edge 232.
[0056] Modular housing 200 has an open position 240 and a closed position 242. In open position, and as shown in
[0057]
[0058] In some embodiments, compartment door 212 includes a peripheral rim 244. As shown in
[0059] Resilient pleat 220 is bendably secured to compartment door 212 and to compartment body 210. In some embodiments, resilient pleat 220 extends between compartment door 212 and compartment body 210. In the illustrated embodiment, resilient pleat 220 extends from fourth side section 230 to peripheral rim 244. Additionally or alternatively, resilient pleat 220 moves with compartment door 212 relative to compartment body 210 between open position 240 and closed position 242. For instance, as shown in
[0060] In some embodiments, compartment door 212 is selectively held in friction fit engagement with compartment body 210 in closed position 242. As shown in
[0061] In some embodiments, a fastener 254 aids in holding compartment door 212 in closed position 242 against compartment body 210. Fastener 254 may attach into a fastening void 256 defined by a side section (e.g., second side section 226). Fastening void 256 may be directed to allow a portion of fastener 254 to pass through fastening void 256 when in closed position 242, as shown in
[0062] Additionally or alternatively, fastener 254 may include clip 258. Clip 258 may secure compartment door 212 in closed position 242 (e.g., by passing through fastening void 256). In some embodiments, clip 258 creates a friction fit engagement with second side section 226 at fastening void 256. In certain embodiments, clip 258 may be flexed to disengage from fastening void 256, allowing modular housing 200 to return to open position 240.
[0063] In some embodiments, fastener 254 may be any fastening mechanism including snaps, clips, or other removably attaching elements to hold compartment door 212 in closed position 242, as known in the art.
[0064] In some alternate embodiments, and as shown in
[0065] Circuit board 204 may be connected to a connector harness (not shown). Connector harness may extend from circuit board 204, through a connector hole 260, and extend out of modular housing 200. Connector hole 260 is defined through compartment door 212. In some embodiments, connector hole 260 is in fluid communication with compartment volume 206 when compartment door 212 is in closed position 242. As would be understood, connector hole 260 allows the connector harness (not shown) to pass through compartment door 212 and into compartment volume 206.
[0066] As described above, modular housing 200 may be attached to beam 202. Beam 202 may be a tube, a flat rail, or an element on appliance 100 defining a screw hole. Generally, modular housing 200 attaches to beam 202 with tube mount 214 if beam 202 is a tube (as shown in
[0067] Turning to
[0068] Tube mount 214 includes a snap 266 curved to accept a round rail or tube 270. Tube mount 214 further includes a first curved foot 262 and a second curved foot 264. In some embodiments, first curved foot 262 and second curved foot 264 comprise snap 266. First curved foot 262 curves laterally opposite to curve of second curved foot 264. First curved foot 262 is spaced apart from second curved foot 264 in cooperative alignment therewith to snap around circular tube 270. In some embodiments, tube mount 214 includes a third curved foot 268. Third curved foot 268 extends from first side section 224, transversely offset from first curved foot 262 and second curved foot 264.
[0069] First curved foot 262 may be offset laterally or transversely from second curved foot 264 on first side section 224. For instance, first curved foot 262 may be laterally spaced apart from second curved foot 264. In some embodiments, first curved foot 262 is transversely parallel to third curved foot 268, with third curved foot 268 laterally in line with first curved foot 262. Additionally or alternatively, first curved foot 262 and third curved foot 268 may be offset adjacent to opposing transverse sides of second curved foot 264. In the illustrated embodiment, second curved foot 264 curves laterally in a curve that curves toward a lateral edge of modular housing 200, and first curved foot 262 curves laterally in a curve that curves opposite to curve of second curved foot 264, toward an opposing lateral edge of modular housing 200. In some embodiments, third curved foot 268 curves in the same direction as first curved foot 262. Generally, curves of first, second, and third curved feet 262, 264, 268 are aligned to accept a tube or round rail. During use, first and second curved feet 262, 264 may snap around tube 270 with tube 270 extending between first curved foot 262 and second curved foot 264. In some embodiments, during use, third curved foot 268 may also snap around tube 270, with tube 270 extending between first and third curved feet 262, 268, and second curved foot 264, as shown in

Additionally or alternatively, flat mount 216 includes a first leg 272, a second leg 278 and a pin leg 274. In some embodiments, first leg 272 and second leg 278 are laterally aligned and transversely offset from one another. As shown in
[0073] As shown especially in
[0074] Returning to
[0075] During use, flat mount 216 can accept a flat rail 280, attaching modular housing 200 to flat rail 280. For instance, flat mount 216 may mount to beam 202 when beam 202 is a flat rail (not shown). Pin bump 282 attaches to flat rail 280 through pin hole (not shown) defined by flat rail 280. Though pin hole is not shown in
[0076] During use, outer pin leg 288 may attach to flat rail 280. In some embodiments, a combination of friction and pressure from outer pin leg 288, inner pin leg 286 with pin bump 282 attaching to flat rail 280 through pin hole, first leg 272, and second leg 278 attach modular housing 200 to flat rail 280.
[0077] Turning generally to
[0078] Screw extension 218 defines a screw hole 284. In some embodiments, screw hole 284 extends laterally through screw extension 218. As shown in FIG.7, screw hole 284 may be supported by a screw hole ridge 285 surrounding screw hole 284. Screw hole ridge 285 may be an outer transverse edge of modular housing 200.
[0079] As shown in
[0080] During use, screw extension 218 may be attached by screw 290 to element 292 with a secondary screw hole (not shown), as shown in
[0081] In additional or alternate embodiments, modular housing 200 may include only two types of mounts, such as tube mount 214 and flat mount 216. In some embodiments, tube mount 214, flat mount 216 or screw extension 218 may be attached or extend from alternate sides of compartment body 210. For example, tube mount 214 may extend from second side section 226 in some embodiments, with flat mount 216 extending from first side section 224. In certain embodiments, screw extension 218 may extend from first side section 224, second side section 226, third side section 228, or fourth side section 230, depending on the needs of the embodiment. Generally, one of tube mount 214, flat mount 216 and screw extension 218 extends from a side section (e.g., first, second, third, or fourth side sections 224, 226, 228, 230) in the set of side sections.
