Blade radius R may define an outer radius or width of auger 252 relative to a radial direction perpendicular to the rotation axis X.

- the direction of the auger blade 258 winding may generally correspond to the intended direction of ice movement along the rotation axis X (e.g., rearward from second blade end 262 to first blade end 260 or, alternatively, forward from first blade end 260 to second blade end 262 ) for ice within storage volume 222 .
- the intended direction of movement for ice is rearward and the auger blade 258 is formed as a right-handed helix from first blade end 260 to second blade end 262 .
- first blade end 260 is generally positioned closer to dispenser opening 226 than second blade end 262 (e.g., along or relative to the transverse direction T). In other words, first blade end 260 may be positioned proximal to dispenser opening 226 while second blade end 262 is positioned distal to dispenser opening 226 .

- auger blade 258 defines multiple turns between which a blade pitch P is generally defined.
- blade pitch P is variable between first blade end 260 and second blade end 262 (e.g., as would be measured along the rotation axis X).
- the longitudinal or axial distance between adjacent turns of auger blade 258 may be different between one (e.g., first) adjacent pair of turns and another (e.g., second) adjacent pair of turns.
- the blade pitch P is a variable pitch that decreases from first blade end 260 to second blade end 262 .

Abstract
Description
- The present subject matter relates generally to ice maker dispensing systems, and in particular to motor assemblies for dispensing systems.
- Certain refrigerator appliances include an ice maker. An ice maker may also be a stand-alone appliance designed for use in commercial and/or residential kitchens. To produce ice, liquid water is directed to the ice maker and frozen. For example, certain ice makers include a mold body for receiving liquid water. After ice is formed in the mold body, it may be stored within an ice bin or bucket within the refrigerator appliance. In order to maintain the ice in a frozen state, the ice bin is positioned within a chilled chamber of the refrigerator appliance or a separate compartment behind one of the doors. In some appliances, a dispenser is provided in communication with the ice bin to automatically dispense a selected or desired amount of ice to a user (e.g., through a door of the refrigerator appliance). Typically, a rotating auger is a provided within the ice bin to help move ice from the ice bin to the dispenser.
- In order to move, e.g., rotate, the auger within the bin, a motor is provided outside of the bin. The motor is part of a motor assembly which is typically housed within a single enclosure that contains multiple components, e.g., both the motor and a driver circuit connected thereto.
- However, such motor assemblies with a single enclosure create certain disadvantages. For example, the entire enclosure must provide sufficient sealing and resilience to meet applicable standards for the motor when reactive refrigerants, e.g., flammable or explosive refrigerants, are used.
- Accordingly, a motor assembly for an ice maker with features for improved mounting and isolation of the components of the motor assembly would be useful.
- Aspects and advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.
- In a first exemplary embodiment, an ice maker is provided. The ice maker includes a mold for forming ice therein and an ice bin. The ice bin has a bin body defining a storage volume to receive ice formed in the mold within the storage volume. The ice maker also includes an auger extending within the storage volume and a motor assembly. The motor assembly includes a motor in operative communication with the auger. The motor is enclosed within a first housing. The motor assembly also includes a driver circuit in electrical communication with the motor. The driver circuit is enclosed within a second housing.
- In a second exemplary embodiment, a motor assembly for an ice maker is provided. The motor assembly includes a motor in operative communication with an auger of the ice maker. The motor is enclosed within a first housing. The motor assembly also includes a driver circuit in electrical communication with the motor. The driver circuit is enclosed within a second housing.
- These and other features, aspects and advantages of the present invention will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

FIG. 1 provides a perspective view of arefrigerator appliance 100 according to an exemplary embodiment of the present subject matter.Refrigerator appliance 100 includes a cabinet orhousing 120 that generally defines a vertical direction V, a lateral direction L, and a transverse direction T, which are mutually perpendicular, such that an orthogonal coordinate system is generally defined. Thecabinet 120 extends between atop 101 and abottom 102 along the vertical direction V, between aleft side 104 and aright side 106 along the lateral direction L, and between afront 108 and a rear 110 along the transversedirection T. Housing 120 defines chilled chambers for receipt of food items for storage. In particular,housing 120 definesfresh food chamber 122 positioned at oradjacent top 101 ofhousing 120 and afreezer chamber 124 arranged at oradjacent bottom 102 ofhousing 120. As such,refrigerator appliance 100 is generally referred to as a bottom mount refrigerator. It is recognized, however, that the benefits of the present disclosure apply to other types and styles of refrigerator appliances such as, e.g., a top mount refrigerator appliance, a side-by-side style refrigerator appliance or a standalone ice maker appliance. Consequently, the description set forth herein is for illustrative purposes only and is not intended to be limiting in any aspect to any particular refrigerator chamber configuration. -
Refrigerator doors 128 are rotatably hinged to an edge ofhousing 120 for selectively accessingfresh food chamber 122, e.g., at theleft side 104 and theright side 106. In addition, afreezer door 130 is arranged belowrefrigerator doors 128 for selectively accessingfreezer chamber 124.Freezer door 130 is coupled to a freezer drawer (not shown) mounted withinfreezer chamber 124 and slidable along the transverse directionT. Refrigerator doors 128 andfreezer door 130 are shown in the closed configuration inFIG. 1 . -
Refrigerator appliance 100 also includes adispensing assembly 140 for dispensing liquid water and/or ice.Dispensing assembly 140 includes adispenser 142 positioned on or mounted to an exterior portion ofrefrigerator appliance 100, e.g., on one ofdoors 128.Dispenser 142 includes a dischargingoutlet 144 for accessing ice and/or liquid water. Anactuating mechanism 146, shown as a paddle, is mounted below dischargingoutlet 144 for operatingdispenser 142. In alternative exemplary embodiments, any suitable actuating mechanism may be used to operatedispenser 142. For example,dispenser 142 can include a sensor (such as an ultrasonic sensor) or a button rather than the paddle. Auser interface panel 148 is provided for controlling the mode of operation. For example,user interface panel 148 includes a plurality of user inputs (not labeled), such as a water dispensing button and an ice-dispensing button, for selecting a desired mode of operation such as crushed or non-crushed ice. - Discharging
outlet 144 andactuating mechanism 146 are an external part ofdispenser 142 and are mounted in adispenser recess 150.Dispenser recess 150 is positioned at a predetermined elevation convenient for a user to access ice or water and enabling the user to access ice without the need to bend-over and without the need to opendoors 128. In the exemplary embodiment,dispenser recess 150 is positioned at a level that approximates the chest level of a user. -
FIG. 2 provides an interior perspective view of a door ofrefrigerator doors 128.Refrigerator appliance 100 includes a sub-compartment 162 defined onrefrigerator door 128. Sub-compartment 162 may be referred to as an “icebox.”Sub-compartment 162 extends intofresh food chamber 122 whenrefrigerator door 128 is in the closed position. As shown inFIG. 3 , an ice maker orice making assembly 160 may be positioned withinsub-compartment 162.FIG. 3 illustrates selected components of theice making assembly 160 according to one or more embodiments, with an ice storage bin assembly 200 (FIGS. 4-6 ) removed from the sub-compartment 162 to more clearly depict the sub-compartment 162 and other components therein. As will be described in more detail below, ice from theice maker 160 is collected and stored in an ice storage bin assembly 200 (FIGS. 4-6 ) and supplied to dispenser recess 150 (FIG. 1 ) from the icestorage bin assembly 200 insub-compartment 162 on a back side ofrefrigerator door 128. Chilled air from a sealed system (not shown) ofrefrigerator appliance 100 may be directed into components withinsub-compartment 162, e.g.,ice maker 160 and/or icestorage bin assembly 200. As mentioned above, the present disclosure may also be applied to other types and styles of refrigerator appliances such as, e.g., a top mount refrigerator appliance, a side-by-side style refrigerator appliance or a standalone ice maker appliance. Accordingly, the description herein of theicebox 162 on thedoor 128 of thefresh food chamber 122 is by way of example only. In other example embodiments, theice maker 160 may be positioned in thefreezer chamber 124, e.g., of the illustrated bottom-mount refrigerator, a side by side refrigerator, a top-mount refrigerator, or any other suitable refrigerator appliance. As another example, theice maker 160 may also be provided in a standalone icemaker appliance. - An
access door 166 is hinged to the inside of therefrigerator door 128.Access door 166 permits selective access tosub-compartment 162. Any manner ofsuitable latch 168 is configured with sub-compartment 162 to maintainaccess door 166 in a closed position. As an example, latch 168 may be actuated by a consumer in order to openaccess door 166 for providing access intosub-compartment 162.Access door 166 can also assist with insulatingsub-compartment 162, e.g., by thermally isolating or insulating sub-compartment 162 fromfresh food chamber 122. -
FIG. 3 provides an interior elevation view ofrefrigerator door 128 withaccess door 166 shown in an open position. As may be seen inFIG. 3 ,ice maker 160 is positioned or disposed withinsub-compartment 162.Ice maker 160 includes a mold body orcasing 170. An ice bucket or ice storage bin 200 (FIG. 4 ) is positioned proximate themold body 170 and receives the ice after the ice is ejected from themold body 170. Fromice storage bin 200, the ice can enter dispensingassembly 140 and be accessed by a user as discussed above. In such a manner,ice maker 160 can produce or generate ice. An auger motor 352 (e.g.,FIGS. 7-9 ) may be in mechanical communication with an auger (e.g.,auger 252—FIG. 4 ) ofice storage bin 200. - Operation of
refrigerator appliance 100, includingice maker 160 and dispensingassembly 140 thereof, is controlled by a processing device or controller 190 (FIG. 1 ), e.g., that may be operatively coupled to controlpanel 148 for user manipulation to select features and operations ofice maker 160 and dispensingassembly 140.Controller 190 can operate various components ofice maker 160 to execute selected system cycles and features. -
Controller 190 may include a memory and microprocessor, such as a general or special purpose microprocessor operable to execute programming instructions or micro-control code associated with operation ofice maker 160. 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 190 may be constructed without using a microprocessor, e.g., using a combination of discrete analog and/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. Other components of theice maker 160 may be in communication withcontroller 190 via one or more signal lines or shared communication busses. -
Ice maker 160 also includes atemperature sensor 178.Temperature sensor 178 is configured for measuring a temperature ofmold body 170 and/or liquids, such as liquid water, withinmold body 170.Temperature sensor 178 can be any suitable device for measuring the temperature ofmold body 170 and/or liquids therein. For example,temperature sensor 178 may be a thermistor or a thermocouple or a bimetal.Controller 190 can receive a signal, such as a voltage or a current, fromtemperature sensor 190 that corresponds to the temperature of themold body 170 and/or liquids therein. In such a manner, the temperature ofmold body 170 and/or liquids therein can be monitored and/or recorded withcontroller 190. Some embodiments can also include an electromechanical icemaker configured with a bimetal to complete an electrical circuit when a specific temperature is reached. - Turning now generally to
FIGS. 4 through 6 , various views are provided of an icestorage bin assembly 200 according to exemplary embodiments of the present disclosure.Storage bin assembly 200 may be used within and selectively attached to acabinet 102 of a refrigerator appliance 100 (FIG. 2 ), e.g., within the icebox (sub-compartment) 162 thereof. In exemplary embodiments,storage bin assembly 200 is removably positioned within the sub-compartment 162 below themold body 170 to receive ice cubes from themold body 170 of the ice maker 160 (FIG. 3 ). - As described herein, it is understood that the vertical direction V, lateral direction L, and transverse direction T described within the context of
FIGS. 4 through 6 generally correspond tostorage bin assembly 200 in isolation. However, these directions may also align with (e.g. be parallel to) the respective vertical direction V, lateral direction L, and transverse direction T defined by refrigerator appliance 100 (FIG. 1 ) whenstorage bin assembly 200 is attached tocabinet 102 or mounted to a door 128 (FIG. 1 ) in the closed position. -
Storage bin assembly 200 generally includes abin body 210 extending along the vertical direction V from abottom end 212 to atop end 214.Bin body 210 may generally be formed as a solid, nonpermeable structure having one or more sidewalls 220 defining astorage volume 222 to receive ice therein (e.g., fromice making assembly 160—FIG. 3 ). - In certain embodiments, sidewalls 220 include a
front wall 216 and arear wall 218. Whenbin body 210 is positioned or mounted within sub-compartment 162 (FIG. 3 ),front wall 216 may generally be positioned forward fromrear wall 218. Specifically,rear wall 218 may be positioned proximal todoor 128 whilefront wall 216 is positioned proximal to fresh food compartment 122 (e.g., along the transverse direction T as would be defined when thecorresponding door 128 is in the closed position). Optionally, ahandle 230 may be provided onfront wall 216. For instance, handle 230 may be formed onfront wall 216 such that a user grip is defined at a front end ofbin body 210. Additionally or alternatively, a suitable handle structure may be mounted to another portion ofstorage bin assembly 200. - In additional or alternative embodiments, one portion of
bin body 210 may be formed from a transparent material, such as a suitable rigid polymer (e.g., acrylic, polycarbonate, etc.), through which a user may view the contents ofstorage volume 222. For instance,front wall 216 may be a transparent wall formed from the transparent material. Optionally, eachsidewall 220 may be a transparent wall formed from the transparent material. Additionally or alternatively, each wall (e.g., 220 and 228) may be integrally-formed with the other walls (e.g., such thatbin body 210 is provided as a unitary monolithic member). - At
top end 214,bin body 210 generally defines a bin opening 224 (see, e.g.,FIG. 6 ) through which ice may pass intostorage volume 222. Below top end 214 (e.g., at a bottom end 212),bin body 210 may define adispenser opening 226 through which ice may pass from storage volume 222 (e.g., to dispensingassembly 140—FIG. 1 ). For example,bin body 210 may include a bottom wall 228 (e.g., attached to or integral with sidewalls 220) that definesdispenser opening 226 in communication withstorage volume 222, e.g., whereby ice from thestorage volume 222 may travel from thestorage volume 222 to and through thedispenser opening 226 and from thedispenser opening 226 to discharging outlet 144 (FIG. 1 ). - Optionally,
dispenser opening 226 may be defined as a vertical opening (e.g., parallel to the vertical direction V through bottom wall 228). Thus,dispenser opening 226 may define ahorizontal perimeter 232. Aperimeter wall 234 may extend vertically about dispenser opening 226 (e.g., from bottom wall 228) andhorizontal perimeter 232. Additionally or alternatively,perimeter wall 234 may define at least a portion ofhorizontal perimeter 232. - Generally,
horizontal perimeter 232 defines the horizontal extrema of dispenser opening 226 (e.g., perpendicular to the vertical direction V). In some embodiments, at least two horizontal extrema for thehorizontal perimeter 232 are provided as afront edge 236 and arear edge 238. Generally,front edge 236 is positioned forward fromrear edge 238 andrear edge 238 is positioned rearward from front edge 236 (e.g., along or relative to the transverse direction T).Front edge 236 may be defined proximal tofront wall 216 andrear edge 238 may be defined proximal to the rear wall 218 (e.g., along the transverse direction T). Additionally or alternatively,dispenser opening 226 may be defined closer torear wall 218 than front wall 216 (i.e., proximal torear wall 218 or distal to front wall 216). For instance, the longitudinal distance (e.g., along the transverse direction T) betweenfront edge 236 andfront wall 216 may be greater than the longitudinal distance betweenrear edge 238 andrear wall 218. - In some embodiments, the entirety of
top end 214 is open and unobstructed.Top end 214 andbin opening 224 may be free of any lid or enclosing portion. Optionally, bin opening 224 may define a radial or horizontal maximum of storage volume 222 (i.e., the maximum radial or horizontal width of storage volume 222). Advantageously, bin opening 224 may provide easy and direct access tostorage volume 222 through which ice may pass. A user may thus easily scoop or pour large amounts ice fromstorage volume 222 directly throughbin opening 224. - In certain embodiments, an
auger 252 is provided or mounted (e.g., rotatably mounted) withinstorage volume 222 to selectively direct ice within thestorage volume 222 to thedispenser opening 226. Optionally,auger 252 is positioned abovebottom wall 228 ordispenser opening 226. - As shown, exemplary embodiments of
auger 252 include arotation shaft 254 that extends along a rotation axis X (e.g., perpendicular to the vertical direction V). In the illustrated exemplary embodiments,rotation shaft 254 extends through a sidewall 220 (e.g., rear wall 218) and through at least a portion ofstorage volume 222. During use,auger 252 androtation shaft 254 can thus selectively rotate within storage volume 222 (e.g., relative to bin body 210). - In certain embodiments,
rotation shaft 254 selectively engages auger motor 352 (FIGS. 3 and 8-10 ). For instance, in exemplary embodiments, anadapter key 256 is connected or attached torotation shaft 254. For instance, a portion ofrotation shaft 254 may extend throughbin body 210 andsupport adapter key 256 outside ofstorage volume 222. In some such embodiments,adapter key 256 is fixed torotation shaft 254 and rotatable about rotation axis X. Whenstorage bin assembly 200 is attached to refrigerator appliance 100 (e.g., mounted to adoor 128—FIG. 3 ),adapter key 256 may engageauger motor 352 in a horizontal connection besidebin body 210. In particular embodiments, as described in more detail below, theadapter key 256 may engage adriver 360 coupled to themotor 352 such that theadapter key 256 is engaged with theauger motor 352 via thedriver 360.Adapter key 256 may thus establish mechanical communication betweenauger motor 352 andauger 252. During use,auger motor 352 may motivate rotation ofadapter key 256 androtation shaft 254 about the rotation axis X. - In some embodiments, the horizontal connection between
auger motor 352 androtation shaft 254 permitsstorage bin assembly 200 to slide horizontally (i.e., perpendicular to the vertical direction V) into attachment with refrigerator appliance 100 (FIG. 3 ) without requiring any vertical movement or motion ofstorage bin assembly 200. Advantageously, a user may attach or removestorage bin assembly 200 fromrefrigerator appliance 100 without liftingstorage bin assembly 200. - An
auger blade 258 may be coiled aboutrotation shaft 254 and, thus, generally about the rotation axis X. Specifically,auger blade 258 extends radially outward from or relative torotation shaft 254. As shown,auger blade 258 defines a blade radius R. Blade radius R may define an outer radius or width ofauger 252 relative to a radial direction perpendicular to the rotation axis X. - Generally,
auger blade 258 extends along (e.g., relative to) the rotation axis X from afirst blade end 260 to asecond blade end 262.First blade end 260 may define one axial extreme ofauger blade 258 whilesecond blade end 262 defines an opposite axial extreme. Optionally, the longitudinal or axial length ofauger blade 258 may be less than the longitudinal or axial length ofrotation shaft 254. Thus,auger blade 258 may extend only upon a sub-portion of therotation shaft 254 that is less than the whole of rotation shaft 254 (e.g., the whole portion ofrotation shaft 254 that is positioned within storage volume 222). -
Auger blade 258 may be fixed torotation shaft 254 such thatauger blade 258 androtation shaft 254 rotate in tandem. For instance,auger blade 258 may be fixed fromfirst blade end 260 tosecond blade end 262. Optionally,auger blade 258 may be formed integrally (e.g., as a unitary monolithic element) withrotation shaft 254. - From
first blade end 260 tosecond blade end 262,auger blade 258 may be coiled or wound as a helix in a set direction about the rotation axis X. In other words,auger blade 258 may be formed as a right-handed helix (as pictured) or, alternatively, a left-handed helix fromfirst blade end 260 tosecond blade end 262. The direction of theauger blade 258 winding may generally correspond to the intended direction of ice movement along the rotation axis X (e.g., rearward fromsecond blade end 262 tofirst blade end 260 or, alternatively, forward fromfirst blade end 260 to second blade end 262) for ice withinstorage volume 222. In the illustrated exemplary embodiments, the intended direction of movement for ice is rearward and theauger blade 258 is formed as a right-handed helix fromfirst blade end 260 tosecond blade end 262. - In some embodiments,
first blade end 260 is generally positioned closer todispenser opening 226 than second blade end 262 (e.g., along or relative to the transverse direction T). In other words,first blade end 260 may be positioned proximal todispenser opening 226 whilesecond blade end 262 is positioned distal todispenser opening 226. Rotation ofauger 252 may thus generally motivate ice toward thefirst blade end 260 and towarddispenser opening 226. - In additional or alternative embodiments,
auger blade 258 terminates above (e.g., directly or indirectly over) at least a portion ofdispenser opening 226. For instance, as measured along or relative to the rotation axis X,first blade end 260 may be positioned betweenfront edge 236 andrear edge 238 ofdispenser opening 226. Specifically,first blade end 260 may be positioned forward fromrear edge 238 and rearward fromfront edge 236 relative to the rotation axis X. As ice is motivated toward dispenser opening 226 (e.g., by rotation of auger 252), the movement of ice that is directly guided or motivated byauger 252 may stop abovedispenser opening 226 such that ice is permitted to fall fromice storage volume 222 throughdispenser opening 226. Advantageously, ice motivated byauger 252 may be prevented from being packed or compressed against asidewall 220 or over dispenser opening 226 (e.g., such thatdispenser opening 226 is obstructed by ice clumps). - As noted above,
auger blade 258 defines a blade radius R perpendicular to the rotation axis X. In some embodiments, blade radius R is provided as an expanding radius fromfirst blade end 260 tosecond blade end 262. Thus, the radial width or blade radius R may increase fromfirst blade end 260 to second blade end 262 (e.g., as would be measured along the rotation axis X). In some such embodiments, the blade radius R defines a frusto-conical profile betweenfirst blade end 260 andsecond blade end 262. In additional or alternative embodiments, a shaft diameter D of rotation shaft 254 (e.g., perpendicular to rotation axis X) does not increase fromfirst blade end 260 tosecond blade end 262. For instance, shaft diameter D may remain constant (as pictured) or generally decrease along the rotation axis X fromfirst blade end 260 tosecond blade end 262. - In exemplary embodiments, the increase of blade radius R (e.g., angle of expansion relative to the rotation axis X) is constant from
first blade end 260 tosecond blade end 262. In alternative embodiments (not shown), the increase of blade radius R is variable fromfirst blade end 260 tosecond blade end 262. - As shown,
auger blade 258 defines multiple turns between which a blade pitch P is generally defined. In optional embodiments, blade pitch P is variable betweenfirst blade end 260 and second blade end 262 (e.g., as would be measured along the rotation axis X). In other words, the longitudinal or axial distance between adjacent turns ofauger blade 258 may be different between one (e.g., first) adjacent pair of turns and another (e.g., second) adjacent pair of turns. In exemplary embodiments, the blade pitch P is a variable pitch that decreases fromfirst blade end 260 tosecond blade end 262. Thus, the variable pitch may increase along the rotation axis X fromsecond blade end 262 tofirst blade end 260. In some such embodiments, the increase in blade pitch P is constant (i.e., a constant rate of increase relative to longitudinal distance from second blade end 262). - In additional or alternative embodiments, the increase in blade pitch P from
second blade end 262 tofirst blade end 260 is proportional to the increase in blade radius R fromfirst blade end 260 tosecond blade end 262. An equal or identical volume may optionally be defined between each pair of adjacent turns ofauger blade 258 fromfirst blade end 260 tosecond blade end 262. - Advantageously, a set volume of ice may be motivated by
auger 252 and may be prevented from being packed or compressed (e.g., before exitingstorage volume 222 through dispenser opening 226). - In certain embodiments, a
base platform 264 is provided withinstorage volume 222. For instance,base platform 264 may be mounted onbottom wall 228 to guide or direct at least a portion of ice withinstorage volume 222. In some such embodiments,base platform 264 includes afloor 266 on which ice may be supported withinstorage volume 222. When assembled,floor 266 may be positioned belowrotation shaft 254 orauger blade 258. Additionally or alternatively, asupport post 268 may be provided to support auger 252 (e.g., proximal to second blade end 262). - In additional or alternative embodiments, at least a portion of
base platform 264 is matched to the expanding blade radius R ofauger blade 258. For instance,floor 266 may decrease in vertical height between thefirst blade end 260 and thesecond blade end 262. In some such embodiments,floor 266 defines a complementary shape (e.g., negative profile) to the shape defined byauger blade 258. Notably,base platform 264 may guide ice (e.g., upward) towardauger 252 as the ice is motivated byauger 252 withinstorage volume 222. - In optional embodiments, one or more
internal bounding walls 272 are provided adjacent to auger 252. For instance, a pair ofinternal bounding walls 272 may be provided onbase platform 264 withinstorage volume 222. As shown, in exemplary embodiments, the pair ofinternal bounding walls 272 may be positioned at opposite radial sides of a portion of the auger blade 258 (e.g., at a location between thefirst blade end 260 and thesecond blade end 262 along the rotation axis X). - It is noted that although
internal bounding walls 272 are shown as extending on or directly from base platform, additional or alternative embodiments can include one ormore bounding walls 272 extending from another portion ofstorage bin assembly 200. As an example, one ormore bounding walls 272 may extend directly from (e.g., attached to or integral with) one or more sidewalls 220. As another example, one ormore bounding walls 272 may extend directly from (attached to or integral with) akick plate 274. - In some embodiments, the pair of
internal bounding walls 272 is positioned forward fromfirst blade end 260 and rearward fromsecond blade end 262. Optionally, the pair ofinternal bounding walls 272 may extend from an internal surface of opposite sidewalls 220 (e.g., perpendicular to the rotation axis X). Additionally or alternatively, one or both boundingwalls 272 may define a complementary shape (e.g., negative profile) to the shape defined byauger blade 258. - As
auger 252 rotates withinstorage volume 222, theinternal bounding walls 272 may block or halt movement of a peripheral ice (e.g., ice outward from the blade radius R) and notably prevent ice from compressing at or adjacent todispenser opening 226. - In additional or alternative embodiments, a
kick plate 274 is mounted or held withinice storage volume 222 aboverotation shaft 254 orauger blade 258. As shown,kick plate 274 is spaced apart from rotation axis X. When assembled,kick plate 274 may extend (e.g., along the transverse direction T or rotation axis X) from awall end 276 to afree end 278. Optionally,kick plate 274 may extend inward from at least one sidewall 220 (e.g., atwall end 276 from rear wall 218) and halt or terminate before spanning the entirety ofstorage volume 222. For instance, afree end 278 of thekick plate 274 may be spaced apart (e.g., along the transverse direction T or rotation axis X) fromfront wall 216 such that a vertical gap is formed or defined betweenfront wall 216 andkick plate 274. - In some embodiments, one or more
upper bounding walls 280 extend generally along the vertical direction V (e.g., downward) from an underside ofkick plate 274. For instance, a pair ofupper bounding walls 280 may be positioned at opposite radial sides of a portion of the auger blade 258 (e.g., at a location between thefirst blade end 260 and thesecond blade end 262 along the rotation axis X). Additionally or alternatively, the pair ofupper bounding walls 280 may be positioned at thefree end 278 and further extend rearward therefrom (e.g., toward wall end 276). - In optional embodiments, at least a portion of
kick plate 274 is slanted downward. For instance, the vertical height ofkick plate 274 may generally decrease fromwall end 276 tofree end 278. In some such embodiments, the vertical height may decrease betweenfirst blade end 260 and second blade end 262 (e.g., as would be measured along the rotation axis X). In additional or alternative embodiments,free end 278 is located directly above a portion ofauger blade 258 betweenfirst blade end 260 andsecond blade end 262. During use,kick plate 274 may generally direct ice downward and away fromdispenser opening 226 to a portion ofauger 252. Advantageously,kick plate 274 may prevent excessive ice from accumulating withindispenser opening 226. For example, in some embodiments, thekick plate 274 may be hingedly mounted within thestorage volume 222, e.g., at the free 278 thereof. Thekick plate 274 may pivot about the hinged connection, e.g., thekick plate 274 may drop and rise when theauger 252 rotates. Such movement of thekick plate 274 may advantageously contribute to motivation of ice pieces (nuggets, cubes, etc.) within thestorage volume 222 towards theauger 252. -
FIG. 7 provides another, enlarged, elevation view of the interior of the sub-compartment 162. Similar toFIG. 3 , the sub-compartment 162 is illustrated inFIG. 7 with thebin assembly 200 removed.FIG. 7 illustrates the relative positions of themold body 170 of the ice maker 160 (FIG. 3 ) and an ice dispensing motor assembly 300 (described in more detail below) which houses the auger motor 352 (FIGS. 3 and 8-10 ). Also as may be seen inFIG. 7 , the ice dispensingmotor assembly 300 may be received within a wall of the sub-compartment 162 -
FIG. 8 provides a perspective view of an ice dispensingmotor assembly 300 as may be incorporated into an ice maker and/or refrigerator appliance, for example, but not limited to, theice maker 160 andrefrigerator appliance 100 described above. The ice dispensingmotor assembly 300 may include anauger motor 352 enclosed within afirst housing 302 and adriver circuit 350 enclosed within asecond housing 304. In some embodiments, thesecond housing 304 may include adrain hole 305 defined therein. As will be described in more detail, thefirst housing 302 and thesecond housing 304 may, in some embodiments, be fully separate and distinct structures which define distinct enclosures for themotor 352 and thedriver circuit 350. Themotor 352 may be in mechanical communication with an auger of an ice maker, for example, theauger 252 described above, e.g., via adriver 360 which interfaces with theauger 252, as is generally understood by those of ordinary skill in the art, such as via interengagement between thedriver 360 and the adapter key 256 (FIGS. 4 and 6 ). Themotor 352 may be coupled to thedriver 360 by one or more gears. Thedriver circuit 350 is a circuit board, such as a printed circuit board (sometimes also referred to as a “PCB”). Components such as the motor, gear(s), and PCB, the structure and function of which are well understood by those of ordinary skill in the art, are not illustrated or described in further detail herein for the sake of brevity and clarity. - The
driver circuit 350 may be in communication with a power supply of the refrigerator, such as electrically coupled to the power supply, via a first set ofwires 354. Thedriver circuit 350 is in communication with themotor 352 via a second wire or set ofwires 356. Thus, thedriver circuit 350 may supply power to themotor 352. For example, in some embodiments, thediver circuit 350 may be or include a directional relay, e.g., which receives alternating current (“AC”) power from the power supply of the refrigerator and provides direct current (“DC”) power to themotor 352. In some embodiments, thedriver circuit 350 may be or include an AC circuit which receives AC electrical power from the power supply of therefrigerator 100 and thedriver circuit 350 may provide DC voltage to themotor 352. - In some embodiments, the
motor 352 may be fully and sealingly enclosed within thefirst housing 302 and thedriver circuit 350 may be fully and sealingly enclosed within thesecond housing 304. For example, each of themotor 352 and thedriver circuit 350 may be fully enclosed on all sides and in all directions by therespective housing wires housing - In
FIG. 8 , the ice dispensingmotor assembly 300 is illustrated in a connected position or configuration, with thefirst housing 302 and thesecond housing 304 of the ice dispensingmotor assembly 300 coupled together. As may be seen inFIG. 8 , when thefirst housing 302 and thesecond housing 304 are coupled together, the adjacent walls of eachhousing housing first housing 302 and thesecond housing 304 may be coupled together without fasteners. In other embodiments, thefirst housing 302 and thesecond housing 304 may be coupled together by one or more male-female joints, e.g., dovetail joints, with mechanical fasteners to supplement the male-female joint(s). -
FIG. 9 illustrates a perspective view of the ice dispensingmotor assembly 300 ofFIG. 8 in a disconnected configuration, with thefirst housing 302 and thesecond housing 304 spaced apart from each other. As can be seen fromFIG. 9 , thefirst housing 302 and thesecond housing 304 are entirely separate and distinct structures. For example, thefirst housing 302 andsecond housing 304 are not sub-compartments of a single housing. As may be seen inFIGS. 9 and 10 , each of thefirst housing 302 and thesecond housing 304 separately and independently defines a complete enclosure for respective components located therein, each independent of the other. For example, eachhousing housings FIGS. 9 and 10 , thefirst housing 302 may include abottom wall 308, afront wall 306, a top wall 310 (FIG. 10 ), aleft wall 312, aright wall 314, and a back wall 316 (FIG. 10 ). Also as may be seen inFIGS. 9 and 10 , thefirst housing 302 may also include apanel 330 and at least some of the walls may extend through thepanel 330 on either side of thepanel 330, such as thetop wall 310, as well as theleft wall 312 andright wall 314. Turning briefly toFIG. 7 , thepanel 330 of the ice dispensingmotor assembly 300 may be generally flush with a wall of the sub-compartment 162. Referring again toFIGS. 9 and 10 , thesecond housing 304 may also include a plurality of walls, e.g., at least six walls, which are wholly separate and distinct from thewalls first housing 302. For example, thesecond housing 304 may include afront wall 318, atop wall 320, abottom wall 322, aleft wall 324, aright wall 326 and aback wall 328. As may be seen inFIGS. 9 and 10 , thewalls second housing 304 may be continuous and coextensive at each edge and corner defined by an intersection of two or more of thewalls second housing 304 forms a complete enclosure without any common or shared structure between thefirst housing 302 and thesecond housing 304. - As mentioned above, the adjacent walls of each
housing first housing 302 and thesecond housing 304 are coupled together. Thus, referring toFIGS. 8 through 10 , when thefirst housing 302 and thesecond housing 304 are coupled together, e.g., as illustrated inFIG. 8 , the bottom wall 308 (see, e.g.,FIG. 9 ) of thefirst housing 302 may, in such embodiments, be in direct contact with the top wall 320 (see, e.g.,FIG. 10 ) of thesecond housing 304 and thewalls bottom wall 308 which overlaps with thetop wall 320, and vice versa. - In some embodiments, e.g., as illustrated in
FIG. 8 , thefirst housing 302 and thesecond housing 304 may be coupled together at least in part by at least one male-female joint, such as a box joint or a dovetail joint. In various embodiments, the components of the joint (or joints in some embodiments, such as the examples described below, which include multiple joints) may be snug fit together, or may be press fit, or interference fit. Additionally, in some embodiments, the components of the male-female joint(s) may be bonded together, e.g., with adhesive such as epoxy or glue. Further, in some embodiments, the components of the male-female joint(s) may also or instead be fastened together with one or more mechanical fasteners, such as screws, rivets, bolts, or other mechanical fasteners and combinations thereof. Such mechanical fasteners, e.g., screws, are well understood by those of ordinary skill in the art and, as such, are not specifically illustrated in the accompanying drawings. Thus, in some embodiments, thefirst housing 302 and thesecond housing 304 may be coupled together without fasteners, e.g., the male-female joint(s) may be the only connecting and/or securing mechanisms between thefirst housing 302 and thesecond housing 304. For example, as illustrated inFIG. 8 , thesecond housing 304 may be coupled to thefirst housing 302 by a male-female joint, which in the illustrated example embodiments is a dovetail joint 332, and the dovetail joint 332 may include a male dovetail 334 (FIG. 9 ) and a female dovetail 336 (FIG. 9 ). Moreover, in alternative embodiments, thefirst housing 302 and thesecond housing 304 may be coupled together with fasteners, e.g., in addition to or instead of the male-female joint. - Turning now to
FIG. 10 , in some embodiments, the dovetail joint 332 may be a first dovetail joint, and thefirst housing 302 and thesecond housing 304 may, in such embodiments, also be coupled by a second dovetail joint comprising a secondmale dovetail 338 and a second female dovetail 340 (or, in additional embodiments, the first and second joints may be another type of male-female joints, such as box joints, tab and slot joints, or mortise and tenon joints). As may be seen inFIGS. 8 through 10 generally, first dovetail joint 332 may be on a first side of thefirst housing 302 and thesecond housing 304 and the second dovetail joint may be on a second side of thefirst housing 302 and thesecond housing 304 which is opposite the first side. For example, the firstmale dovetail 334 and the firstfemale dovetail 336 may, in some embodiments, be located on thefront walls 306 and 318 (either respectively as in the illustrated example embodiments, or the relative positions of the firstmale dovetail 334 and the firstfemale dovetail 336 on thefirst housing 302 and thesecond housing 304 may be reversed) while the secondmale dovetail 338 and the secondfemale dovetail 340 may, in such embodiments, be located on theback wall 328 of thesecond housing 304 and theback wall 316 of the first housing 302 (as with the first dovetails, the secondmale dovetail 338 and the secondfemale dovetail 340 may be located on thesecond housing 304 and thefirst housing 302, respectively, as in the illustrated example embodiments, or the relative positions of the secondmale dovetail 238 and the secondfemale dovetail 340 on thefirst housing 302 and thesecond housing 304 may be reversed). Thus, where thefront wall 306 of thefirst housing 302 is opposite theback wall 316 of thefirst housing 302 and thefront wall 318 of thesecond housing 304 is opposite theback wall 328 of thesecond housing 304, the first dovetail joint 332 may be opposite the second dovetail joint. - As best seen in
FIG. 10 , in some embodiments, the ice dispensingmotor assembly 300 may also include a third male-female joint, e.g., a third dovetail joint. The third dovetail joint may include a thirdmale dovetail 342 and a thirdfemale dovetail 344, e.g., as illustrated inFIG. 10 . The thirdmale dovetail 342 and the thirdfemale dovetail 344 may, in some embodiments, be positioned on the same side of theauger motor assembly 300 as, e.g., may be co-planar with, the secondmale dovetail 338 and the secondfemale dovetail 340. - The ice dispensing
motor assembly 300 as disclosed herein may provide numerous advantages. For example, by virtue of theseparate housings - 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. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they include structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
