It should be appreciated that the appliance ofFIG. 1 is for illustrative purposes only and that the present invention is not limited to any particular type, style, or configuration of refrigeration appliance, and that such appliance may include any manner of refrigerator, freezer, refrigerator/freezer combination, and so forth. The present disclosure may be especially suitable for a compact refrigerator and/or freezer appliance where space is at a premium and an ice-making capability is desired. However, the disclosed ice-making assembly may be used with any such appliance. - Referring to
FIG. 2 therefrigerator 10 includes a freshfood storage compartment 12 and afreezer storage compartment 14, with the compartments arranged side-by-side and contained within anouter case 16 andinner liners 18 and 20 generally made from a suitable plastic or metal material. Insmaller refrigerators 10, a single liner is formed and a mullion spans between opposite sides of the liner to divide it into a freezer storage compartment and a fresh food storage compartment. Theouter case 16 is normally formed by folding a sheet of a suitable material, such as pre-painted steel, into an inverted U-shape to form top and side walls of theouter case 16. A bottom wall of theouter case 16 normally is formed separately and attached to the case side walls and to a bottom frame that provides support forrefrigerator 10. - A
breaker strip 22 extends between a case front flange and outer front edges ofinner liners 18 and 20. Thebreaker strip 22 is formed from a suitable resilient material, such as an extruded acrylo-butadiene-styrene based material (commonly referred to as ABS). The insulation in the space betweeninner liners 18 and 20 is covered by another strip of suitable resilient material, which also commonly is referred to as amullion 24 and may be formed of an extruded ABS material.Breaker strip 22 andmullion 24 form a front face, and extend completely around inner peripheral edges of theouter case 16 and vertically betweeninner liners 18 and 20. - Slide-out
drawers 26, astorage bin 28 andshelves 30 are normally provided in freshfood storage compartment 12 to support items being stored therein. In addition, at least oneshelf 30 and at least onewire basket 32 are also provided infreezer storage compartment 14. - The refrigerator features are controlled by a
controller 34 according to user preference via manipulation of acontrol interface 36 mounted in an upper region of freshfood storage compartment 12 and coupled to thecontroller 34. As used herein, the term “controller” is not limited to just those integrated circuits referred to in the art as microprocessor, but broadly refers to computers, processors, microcontrollers, microcomputers, programmable logic controllers, application specific integrated circuits, and other programmable circuits, and these terms are used interchangeably herein. - A
freezer door 38 and afresh food door 40 close access openings tofreezer storage compartment 14 and freshfood storage compartment 12. Eachdoor top hinge 42 and a bottom hinge (not shown) to rotate about its outer vertical edge between an open position, as shown inFIG. 1 , and a closed position. Thefreezer door 38 may include a plurality ofstorage shelves 44 and a sealinggasket 46, andfresh food door 40 also includes a plurality ofstorage shelves 48 and a sealinggasket 50. - The
freezer storage compartment 14 may include anautomatic ice maker 52 and adispenser 54 provided in thefreezer door 38 such that ice and/or chilled water can be dispensed without opening thefreezer door 38, as is well known in the art.Doors handles 56 is conventional. Ahousing 58 may hold awater filter 60 used to filter water for theice maker 52 and/ordispenser 54. - As with known refrigerators, the
refrigerator 10 also includes a machinery compartment (not shown) that at least partially contains components for executing a known vapor compression cycle for cooling air. The components include a compressor, a condenser, an expansion device, and an evaporator connected in series as a loop and charged with a refrigerant. The evaporator is a type of heat exchanger which transfers heat from air passing over the evaporator to the refrigerant flowing through the evaporator, thereby causing the refrigerant to vaporize. The cooled air is used to refrigerate one or more refrigerator or freezer compartments via fans. Also, a cooling loop can be added to directly cool the ice maker to form ice cubes, and a heating loop can be added to help remove ice from the ice maker. Collectively, the vapor compression cycle components in a refrigeration circuit, associated fans, and associated compartments are conventionally referred to as a sealed system. The construction and operation of the sealed system are well known to those skilled in the art. - As shown in
FIGS. 3 and 4 , anice dispensing assembly 100 includes anice bucket 102 that can be mounted withinrefrigeration appliance 10. As shown,ice bucket 102 is mounted to an interior offreezer door 38, although it could be mounted to therefrigerator door 40 as well, or in therefrigerator compartment 12 orfreezer compartment 14. Ice maker 52 (shown in dotted lines) would be most likely mounted infreezer compartment 14 ifice bucket 102 is mounted tofreezer door 38 so thatice cubes 104 can drop from the ice maker into the ice bucket when made. However, as is known,ice maker 52 could be mounted inrefrigerator compartment 12 and cooled in some way, such as by providing cooled air from freezer compartment to the area of the ice maker to cool it sufficiently to make ice. Accordingly, it should be understood that various options are possible for mountingice bucket 102 andice maker 52 withinrefrigerated appliance 10, its various compartments or its doors. -
Ice bucket 102 includesside walls 106 and abottom wall 108. Afirst exit 110 and asecond exit 112 are provided inbottom wall 108. Both exits lead to aconduit 114 that leads eventually to an opening (not shown) throughdoor 38 withindispenser 54. Trapdoors, seals, etc. may be provided between the exits and the dispenser for thermal reasons as is known, either within the exits or below. - A
first motor 116 is provided for moving arotatable member 118 to moveice cubes 104 fromice bucket 102 throughfirst exit 110. As shown,ice cubes 104 that drop fromice maker 52 will fall to the bottom area ofice bucket 102 nearrotatable member 118 andfirst exit 110. Eventually, enough ice can be made to fully cover this area. If desired,rotatable member 118 may be concentrically or non-concentrically mounted onshaft 120. Mountingrotatable member 118 non-concentrically may allow ice to be “throttled” downward more forcefully throughexit 110 while breaking up clumps and pulling accumulated ice down from above. If desired,rotatable member 118 may have a ridged, grooved, etc.outer surface 122 to assist in grabbing and pushing ice. Alternatively,rotatable member 118 could be concentrically mounted but have a somewhatnon-uniform surface 122 shape to assist in moving ice as desired.Rotating element 120, when stopped, also provides a “shut off” to stop the flow of ice to the exit at the end of the dispense cycle. - A
second motor 124 is provided to move twocounter-rotating members 126 to grindice cubes 104 from theice bucket 102 between them into crushed ice and to move the crushed ice through thesecond exit 112. As shown,counter-rotating members 126 are mounted toshafts 128 connected via gearing 130 at a base end nearsecond motor 124. The spacing betweenshafts 128 and/or the diameter ofmembers 126 may be selected to provide crushed ice of a desired size.Members 126 may have teeth, as shown, or other shapes to help pullice cubes 104 down between the members for crushing and pass them towardsecond exit 112. If desired, aguide 132 may be provided proximatecounter rotating members 126 for guiding ice cubes to and through the counter rotating members. As shown, guide 132 is cup shaped and extends upward aboveexit 112. Use of such guide helps direct ice cubes in the right direction toward the crushing counter-rotating members and also keeps crushed ice from missingsecond exit 112, either to fall in the bottom ofice bucket 102 or passing outfirst exit 110. -
Ice dispensing assembly 100 therefore provides a simple and reliable source of both ice cubes and crushed ice. The feeds of crushed ice and ice cubes are not mixed, so a user gets only what is desired, not the tail end of a previously dispensed quantity of cubed or crushed ice. The dual motors allow each side of the ice bucket to operate independently. Complicated auger mechanisms are avoided. -
FIGS. 5 and 6 show another example of an ice dispensing assembly. As shown,assembly 200 also includes anice bucket 202 mounted to afreezer door 38, although it could be mounted to therefrigerator door 40 as well, or in therefrigerator compartment 12 orfreezer compartment 14. Therefore, as above, various optional locations and arrangements are possible. -
Ice bucket 202 has only oneexit 210 in thebottom wall 208. Afirst motor 216 moves arotatable member 218 to moveice cubes 104 from the ice bucket through the exit.Rotatable member 218 as shown is concentrically mounted onshaft 220 and has a plurality of teeth for gripping and pulling down ice cubes. - A
second motor 224 moves acrush element 225 toward or away from therotatable member 218.Second motor 224 may accordingly be a solenoid motor. As shown, thecrush element 225 is a plate slidable on aramp 227 formed atopbottom wall 208 orside wall 202. A distal end of 229 oframp 227 extends into or overexit 210. Crush 225 element is movable between a first position toward rotatable member 218 (as inFIG. 5 ) and a second position away from the rotatable member (seeFIG. 6 ). When in the position towardrotatable member 218,crush member 225 narrows the width of the passageway for ice cubes moving downward throughexit 210, thereby cooperating with the rotatable member when rotated to grind ice cubes into crushed ice. Thecrush element 225 also serves as a “shut off” over the exit when the ice dispense cycle is over androtating element 218 is no longer turning. When pulled back fromrotatable member 218,crush element 225 allows ice cubes to pass out ofexit 210 without crushing via rotation of the rotatable member. In other words, when moved back,crush element 225 provides enough space for ice cubes to be pulled down and passed throughexit 210 without being crushed.Structure 231 may be provided on anoutput shaft 228 ofsecond motor 224, such as an eccentric, a slider, a rack and pinion arrangement, etc., to allowcrush element 225 to slide back and forth under the direction of the second motor. - Accordingly, the device of
FIGS. 5 and 6 provides a reliable and simpleice dispensing assembly 200 for providing cubed or crushed ice as desired. Again, complicated auger mechanisms are avoided, and two small motors are used for the various functionality. - 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.
