Description
- The present disclosure relates generally to dishwasher appliances, and more particularly to improved spray arm assemblies for dishwasher appliances.
- Dishwasher appliances generally include a tub that defines a wash compartment. Rack assemblies can be mounted within the wash compartment of the tub for receipt of articles for washing. During wash and rinse cycles, spray assemblies within the wash compartment can apply or direct wash fluid (e.g. various combinations of water and detergent along with optional additives) towards articles disposed within the rack assemblies in order to clean such articles.
- Multiple spray assemblies can be provided including e.g., a lower spray arm assembly mounted to the tub at a bottom of the wash compartment, a mid-level spray arm assembly mounted to one of the rack assemblies, and/or an upper spray assembly mounted to the tub at a top of the wash compartment. Other configurations may be used as well.
- One limitation of many currently known spray arm assemblies is the geometry of the spray arm assemblies relative to the geometry of the dishwasher appliance interior. Most known spray arm assemblies utilize a generally circular geometry. For example, an arm of a spray arm assembly may rotate in a circle, and jets or apertures defined in the arm may emit wash fluid from the arm in this circular pattern. Each jet emits fluid in a constant direction from the associated arm during rotation, so that the locations reached by the wash fluid are predictable and limited. Further, the cross-sectional interior geometry of most currently known dishwasher appliances is square or rectangular. Accordingly, the corners of such dishwasher appliance, and the articles located therein, may not be sufficiently reached by wash fluid. These limitations can result in articles not being properly cleaned during operation of the dishwasher appliance.
- Accordingly, improved spray arm assemblies and associated dishwasher appliances are desired in the art. In particular, improved spray arm assembly designs which increase the coverage of the wash fluid emitted therefrom would be advantageous.
- 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 accordance with one embodiment of the present disclosure, a spray arm assembly for a dishwasher appliance is provided. The spray arm assembly includes a first spray arm, the first spray arm including an inner arm member and an outer arm member, the inner arm member defining an interior and extending along a longitudinal axis, the outer arm member generally concentric with and surrounding the inner arm member. The inner arm member is rotatable about the longitudinal axis, and defines an inner slot extending helically along the longitudinal axis. The outer arm member defines an outer slot extending generally linearly along the longitudinal axis.
- In accordance with another embodiment of the present disclosure, a spray arm assembly for a dishwasher appliance is provided. The spray arm assembly includes a first spray arm, the first spray arm including an inner arm member and an outer arm member, the inner arm member defining an interior and extending along a longitudinal axis, the outer arm member generally concentric with and surrounding the inner arm member. The inner arm member is rotatable about the longitudinal axis. The spray arm assembly further includes a central housing defining and rotatable about a central axis, the central axis generally perpendicular to the longitudinal axis. The spray arm assembly further includes a bevel gear assembly disposed within the central housing. The bevel gear assembly is configured to rotate the inner arm member about the longitudinal axis when the central housing rotates about the central axis. The bevel gear assembly includes a drive gear, an axle gear, and an idler gear, the axle gear mounted to the inner arm member.

Spray arm assembly 200 may include one or more spray arms. For example, as illustrated,spray arm assembly 200 may include one or morefirst spray arms 202. Eachfirst spray arm 202 may include aninner arm member 204.Inner arm member 204 may define an interior 206. Further,inner arm member 204 may extend along and define alongitudinal axis 208, and may extend between a base 210 and atip 212 along thelongitudinal axis 208. Afirst spray arm 202 may further include anouter arm member 214. Theouter arm member 214 may define an interior 216, and may generally surround theinner arm member 204 such that the inner arm member 204 (or at least a substantial portion thereof) is disposed within the interior 216.Outer arm member 214 may extend between a base 220 and atip 222. Further,outer arm member 214 may be generally concentric with theinner arm member 204, and thus similarly extend along thelongitudinal axis 208 defined by theinner arm member 204. -
Spray arm assembly 200 may further include acentral housing 230 that defines an interior 232. Thecentral housing 230 may further define acentral axis 234 therethrough, which may for example be generally perpendicular to the longitudinal axis or axes 208 of the inner arm member(s) 204.Central housing 230 may, for example, be rotatable about thecentral axis 234. -
Housing 230 may be in fluid communication with thefluid circulation assembly 152 to receive wash fluid therefrom. Accordingly, wash fluid may flow into thehousing 230 thoughinlet 236. The wash fluid may then flow from thehousing 230 to the various spray arms of thespray arm assembly 200, including for example thefirst spray arms 202 and second spray arms as discussed herein. - A
first spray arm 202 in accordance with the present disclosure may further operate to emit wash fluid therefrom in an improved manner which advantageously increases the wash fluid coverage within thedishwasher appliance 100. For example,inner arm member 204 may be rotatable about thelongitudinal axis 208. Apertures or slots, as discussed herein, may be defined in theinner arm member 204 to emit wash fluid therethrough from theinterior 206 of theinner arm member 204. Theinner arm member 204 may, for example, be in fluid communication with thehousing 230 such that wash fluid flows from the interior 232 into the interior 206. This wash fluid can then be emitted through the apertures or slots. -
Outer arm member 214 may, for example, be generally stationary relative to thelongitudinal axis 208. For example, theouter arm member 214, such as thebase 220 thereof, may be mounted to thecentral housing 230. In some embodiments, theouter arm member 214 may be integral with thecentral housing 230, while in other embodiments theouter arm member 214 may be a separate component connected to thecentral housing 230 via a suitable adhesive, mechanical fastener, etc. Apertures or slots, as discussed herein, may be defined in theouter arm member 214 to emit wash fluid therethrough from the interior 216 of theouter arm member 214. Theouter arm member 214 may, for example, be in fluid communication with theinner arm member 204 such that wash fluid flows from the interior 206 into the interior 216. This wash fluid can then be emitted through the apertures or slots. - In exemplary embodiments, as shown,
inner arm member 204 may define one or moreinner slots 240, which may extend along at least a portion of theinner arm member 204 between the base 210 and thetip 212. Theslot 240 may be in fluid communication with the interior 206, and thus allow wash fluid to flow from the interior 206 therethrough to exit theinner arm member 204. Further, in exemplary embodiments, theinner slot 240 may be a helicalinner slot 240, thus extending helically along thelongitudinal axis 208 as shown. - Further, in exemplary embodiments, as shown, the
outer arm member 214 may define one or moreouter slots 242, which may extend along at least a portion of theouter arm member 214 between the base 220 and thetip 222. Theslot 242 may be in fluid communication with the interior 216, and thus allow wash fluid to flow from the interior 216 therethrough to exit theouter arm member 214. Further, in exemplary embodiments, theouter slot 242 may be a generally linearouter slot 242, thus extending generally linearly along thelongitudinal axis 208 as shown. - Accordingly, in for example embodiments wherein the
inner arm member 204 includes a helicalinner slot 240 and theouter arm member 214 includes a generally linearouter slot 242, rotation of theinner arm member 204 about thelongitudinal axis 208 and relative to theouter arm member 214 may cause different portions of theslot 240 to align with theouter slot 242 at different times during operation. This may thus cause the wash fluid to be emitted from theouter arm member 214 at a variety of locations alongouter slot 242 during operation, thus advantageously providing increased wash fluid coverage. - As discussed,
inner arm members 204 in accordance with the present disclosure may be rotatable about theirlongitudinal axes 208. In exemplary embodiments, agear assembly 250 may be disposed within thecentral housing 230.Gear assembly 250 may be configured to rotate the inner arm member(s) 204 about theirlongitudinal axes 208. In exemplary embodiments, agear assembly 250 may be configured to rotate inner arm member(s) 204 about theirlongitudinal axes 208 when thecentral housing 230 rotates about thecentral axis 234, and due to this rotation. - For example and as shown,
gear assembly 250 may be abevel gear assembly 250, with the various gears thereof having a bevel-style arrangement.Gear assembly 250 may include, for example, adrive gear 252 and one or more axle gears 254. Eachaxle gear 254 may be mounted to an associatedinner arm member 204. In some embodiments, anaxle gear 254 may be integral with the associatedinner arm member 206, while in other embodiments theaxle gear 254 may be a separate component connected to the associatedinner arm member 204 via a suitable adhesive, mechanical fastener, etc. -
Gear teeth 253 of thedrive gear 252 may mesh withgear teeth 255 of the axle gears 254, and thedrive gear 252 may drive the axle gears 254. Rotation of anaxle gear 254 may cause rotation of the associatedinner arm member 204 about itslongitudinal axis 208. For example,central housing 230 and thefirst spray arms 202 and associated axle gears 254 may be rotatable about thecentral axis 234 relative to thedrive gear 252. Due to the meshing of thedrive gear 252 and axle gears 254, this rotation may cause thedrive gear 252 to drive rotation of the axle gears 254 about the associatedlongitudinal axes 208 of the associatedinner arm members 204, thus causing rotation of the associatedinner arm members 204 about theirlongitudinal axes 208. - Further, in some embodiments, the number of
gear teeth 255 of anaxle gear 254 may be different from the number ofgear teeth 253 of adrive gear 252. In exemplary embodiments, the number ofgear teeth 255 of anaxle gear 254 may be less than the number ofgear teeth 253 of adrive gear 252. Alternatively, the number ofgear teeth 255 of anaxle gear 254 may be more than the number ofgear teeth 253 of adrive gear 252. The resulting gear ratio may advantageously cause the location of emitted wash fluid along anouter arm member 214 to be varied for each location of theouter arm member 214 during rotation about thecentral axis 234, thus advantageously providing increased wash fluid coverage. - In some embodiments,
gear assembly 250 may further include anidler gear 256, as shown, which may includegear teeth 257 that mesh withteeth 255 of axle gears 254.Idler gear 256 may advantageously provide stability to thegear assembly 250 and reduce binding during operation thereof. - As further illustrated,
spray arm assembly 200 may include one or moresecond spray arms 260. Eachsecond spray arm 260 may include anarm member 262.Arm member 262 may define an interior 264. Further,arm member 262 may extend along and define alongitudinal axis 266, and may extend between a base 270 and atip 272 along thelongitudinal axis 266. -
Arm member 262 may, for example, be generally stationary relative to thelongitudinal axis 266. For example, thearm member 262, such as thebase 270 thereof, may be mounted to thecentral housing 230. In some embodiments, thearm member 262 may be integral with thecentral housing 230, while in other embodiments thearm member 262 may be a separate component connected to thecentral housing 230 via a suitable adhesive, mechanical fastener, etc. Apertures or slots, as discussed herein, may be defined in thearm member 262 to emit wash fluid therethrough from theinterior 264 of thearm member 262. Thearm member 264 may, for example, be in fluid communication with thecentral housing 230 such that wash fluid flows from the interior 232 into the interior 264. This wash fluid can then be emitted through the apertures or slots. - In exemplary embodiments as shown, the
arm member 262 of asecond spray arm 260 may define one ormore apertures 276. In particular theapertures 276 may bedrive jet apertures 276, which may emit wash fluid at an orientation that drives rotation of thespray arm 260, and thus thecentral housing 230 andfirst spray arms 202, about thecentral axis 232. In exemplary embodiments, as shown, aperture(s) 276 may be disposed proximate thetip 272 of thearm member 262. - First and
second spray arms central axis 234. For example, in exemplary embodiments when more than onefirst spray arm 202 is utilized, thespray arms 202 may be arrayed about thecentral axis 234, such as generally equally spaced apart about thecentral axis 234. For example, twofirst spray arms 202 may be spaced approximately 180 degrees apart from each other about thecentral axis 234, threefirst spray arms 202 may be spaced approximately 120 degrees apart from each other about thecentral axis 234, fourfirst spray arms 202 may be spaced approximately 90 degrees apart from each other about thecentral axis 234, etc. Similarly, in exemplary embodiments when more than onesecond spray arm 260 is utilized, thespray arms 260 may be arrayed about thecentral axis 234, such as generally equally spaced apart about thecentral axis 234. For example, twosecond spray arms 260 may be spaced approximately 180 degrees apart from each other about thecentral axis 234, threesecond spray arms 260 may be spaced approximately 120 degrees apart from each other about thecentral axis 234, foursecond spray arms 260 may be spaced approximately 90 degrees apart from each other about thecentral axis 234, etc. Additionally, in exemplary embodiments wherein both first andsecond spray arms arms central axis 234, such as generally equally spaced apart about thecentral axis 234. Further, in exemplary embodiments wherein both first andsecond spray arms arms central axis 234. - This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods.
