The static jet assembly and the basket may be positioned within a rack assembly of the dishwashing appliance to spray utensils within a basket. Wash fluid may supplied from the static jet assembly and directed at an internal portion of the basket.
(20) Turning now to the figures,
(21) The tub 104 may define a discrete vertical direction V, lateral direction L, and transverse direction T. Vertical direction V, lateral direction L, and transverse direction T are orthogonally oriented such that vertical direction V, lateral direction L, and transverse direction T form an orthogonal directional system.
(22) As is understood, the tub 104 may generally have a rectangular cross-section defined by various wall panels or walls. For example, as shown in
(23) As particularly shown in
(24) In some embodiments, a basket 170 is removably mounted to lower rack assembly 122. However, in alternative exemplary embodiments, the basket 170 may also be selectively attached to other portions of dishwashing appliance 100, e.g., upper rack assembly 120 or door 108. The basket 170 defines one or more storage chambers and is generally configured to receive of silverware, flatware, utensils, and the like, that are too small to be accommodated by the upper and lower rack assemblies 120, 122. The basket 170 may be constructed of any suitable material, e.g., metal or plastic, and define a plurality of fluid slots 178 for permitting wash fluid therethrough.
(25) The dishwashing appliance 100 includes one or more spray assemblies housed within the wash chamber 106. For instance, the dishwashing appliance 100 may include a lower spray-arm assembly 130 that is rotatably mounted within a lower region 132 of the wash chamber 106 directly above the bottom wall 162 of the tub 104 so as to rotate in relatively close proximity to the rack assembly 122. As shown in
(26) As is generally understood, the lower and mid-level spray-arm assemblies 130, 136 and the upper spray assembly 138 may generally form part of a fluid circulation assembly 140 for circulating fluid (e.g., water and dishwasher fluid) within the tub 104. As shown in
(27) It should be appreciated that, although the dishwashing appliance 100 will generally be described herein as including three spray assemblies 130, 136, 138, the dishwashing appliance may, in alternative embodiments, include any other number of spray assemblies, including two spray assemblies, four spray assemblies or five or more spray assemblies. For instance, in addition to the lower and mid-level spray-arm assemblies 130, 136 and the upper spray assembly 138 (or as an alternative thereto), the dishwashing appliance 100 may include one or more other spray assemblies and/or wash zones for distributing fluid within the wash chamber 106.
(28) In addition to the three spray assemblies 130, 136, 138, the appliance also includes a static jet assembly 300 disposed within the wash chamber 106. In some embodiments, the static jet assembly 300 may remain generally stationary during use of the dishwashing appliance 100, i.e., such that there is no intentional movement of static jet assembly 300 outside of vibration, etc. In additional or alternative embodiments, one or more movable nozzles (not pictured) may be provided on a static body 304 to rotate during use of the dishwashing appliance 100, e.g., while static body 304 remains stationary.
(29) The static jet assembly 300 may be positioned to direct wash fluid to a certain predetermined location within the wash chamber 106, e.g., a predetermined subsection of the wash chamber 106. For instance, the static jet assembly 300 may be disposed, e.g., on or within the lower rack assembly 122, within the wash tub 104 and directed toward the basket 170. In exemplary embodiments, the static jet assembly 300 may provide advantageously focused cleaning to utensils within the basket 170 without significantly blocking spray from a spray assembly, e.g., lower spray-arm assembly 130.
(30) The dishwashing appliance 100 may be further equipped with a controller 146 configured to regulate operation of the dishwasher 100. The controller 146 may generally include one or more memory devices and one or more microprocessors, such as one or more 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.
(31) The controller 146 may be positioned in a variety of locations throughout dishwashing appliance 100. In the illustrated embodiment, the controller 146 is located within a control panel area 148 of the door 108, as shown in
(32) Additionally, as shown in
(33) Moreover, as shown in
(34) It should be appreciated that the present subject matter is not limited to any particular style, model, or configuration of dishwashing appliance. The exemplary embodiments depicted in
(35) Referring now to
(36) As illustrated in
(37) In some embodiments, at least a portion of the static jet assembly 300, e.g., the static body 304, is mounted to a rack assembly 314. It should be noted that the rack assembly 314 may be embodied as a lower rack assembly 122 or an upper rack assembly 120, as illustrated in
(38) As illustrated in
(39) In some embodiments, the conduit passage 322 includes a Venturi portion 328 (see
(40) An air gap 330 may be defined, e.g., in the vertical direction V, between a bottom portion of the fluid conduit 302 and a wall of the tub 104. For instance, as illustrated, the air gap 330 may be defined between the fluid conduit 302 and the bottom wall 162. Optionally, a drain hole 332 may be defined through the fluid conduit 302, e.g., at the bottom portion of the fluid conduit 302. The drain hole 332 may be in fluid communication between the conduit passage 322 and the wash chamber 106 and/or air gap 330. In certain embodiments, the drain hole 332 is defined through the fluid conduit 302 along the Venturi portion 328. Once pressurized wash fluid is no longer supplied to the fluid conduit 302, e.g., from the pump 142 (
(41) As noted above, the fluid conduit 302 may selectively attach to the static body 304. Specifically, the static body 304 defines an inlet 334 that may be separably connected to the fluid conduit 302, e.g., at the conduit outlet 326. The connection between the static body 304 and the fluid conduit 302 may be alternately formed and broken as the static body 304 slides into and out of the wash chamber 106, e.g., with the rack assembly 314 (
(42) As illustrated in
(43) In some embodiments, the basket 170 is disposed on the static body 304. Optionally, the static body 304 may be formed to complement the shape and/or perimeter of the basket 170. At least a portion of basket 170 may extend across the upper face 310. One or more support ridges 342 may extend from the upper face 310, e.g., in the vertical direction V. A lower rim 344 may extend from the bottom 174 of the basket 170, e.g., in the vertical direction V about a perimeter portion of the bottom 174. The basket 170 may be positioned on the static body 304 such that the support ridges 342 engage the lower rim 344. When assembled, the upper face 310 may be spaced apart from the bottom 174 of the basket 170. A channel 346 may be defined between the upper face 310 and the basket 170. Wash fluid may fall or drain from the basket 170 through the channel 346, and across around the upper face 310, and to the lower face 311. Falling wash fluid from the basket 170 is thus directed away from the interior passage 306 of the static body 304. Optionally, one or more of the jet apertures 312 may be aligned with the fluid slots 178 of the basket 170. In some such embodiments, each of the plurality of jet apertures 312 is aligned in fluid communication with a discrete slot 178 of the plurality of fluid slots 178. During operations of the static jet assembly 300, wash fluid may pass unimpeded from each jet aperture 312 to an internal portion or storage chamber of the basket 170.
(44) In optional embodiments, one or more drain holes 315 are defined through the static body 304, e.g., at the lower face 311. The drain hole(s) 315 may be in fluid communication between the interior passage 306 and the wash chamber 106 (
(45) As shown, the jet apertures 312 may be defined at an angle, e.g., such that wash fluid therefrom is directed along the same angle. In certain embodiments, one or more of the plurality of jet apertures 312 are defined at an angle relative to the vertical direction V. For instance, each jet aperture 312 may be defined along a surface radius 313 of upper face 310 such that wash fluid is dispensed at the angle . Each angle may be defined relative to the vertical direction V. One or more jet aperture 312 may be defined at an angle between 20 and 80. In certain embodiments, each of the plurality of jet apertures 312 is defined at an angle between 40 and 70. The angle of each jet aperture 312 may be identical to or distinct from the other apertures 312. In other words, each angle may be identical to or distinct of each other angle .
(46) Some embodiments of static body 304 extend about one or more exterior holes 308. Each exterior hole 308 may extend along a central axis CA, e.g., parallel to the vertical direction V from the upper face 310 of the static body 304 to the lower face 311 of the static body 304. Exterior hole 308 may thus provide a void through which fluid may pass, independent of the jet apertures 312.
(47) In some embodiments, the jet apertures 312 are radially disposed about one or more exterior holes 308. Optionally, one or more of the plurality of jet apertures 312 are defined at an angle directed toward the central axis CA. Each angle may thus be defined relative to the central axis CA. One or more jet aperture 312 may be defined at an angle between 20 and 80. In certain embodiments, each of the plurality of jet apertures 312 is defined at an angle between 40 and 70. The angle of each jet aperture 312 may be identical to or distinct from the other apertures 312. In other words, each angle may be identical to or distinct of each other angle .
(48) As noted above, the static body 304 may be formed to complement the shape of the basket 170. For instance, in exemplary embodiments wherein the basket 170 has three distinct storage chambers (such as the embodiments shown in
(49) During use, wash fluid, e.g., from the lower spray assembly 130, may advantageously flow through the exterior hole(s) 308 without hindering the flow of wash fluid from the jet apertures 312. In certain embodiments wherein multiple exterior holes 308 are defined, the central axis CA of each exterior hole 308 may be parallel to the others. Additionally or alternatively, one or more central axes CA may be parallel to the vertical direction V.
