Auger style ice maker and refrigeration appliance incorporating same
An ice making assembly includes a mold configured for forming an ice cube. The mold has a base, a side wall, and an opening in the side wall spaced from the base. An auger has a shaft with a proximal end above and outside of the mold, a distal end within the mold, and a central section between the distal end and the proximal end and extending through the opening. The auger further has a threaded portion configured for moving the ice cube out of the mold through the opening via rotation of the auger. A motor may be located above the mold and attached to the proximal end of the shaft for rotating the auger to lift the ice cube from the mold. The ice cubes may be formed with a gap and a splitter may split the ice cubes at the gap.
1. An ice making assembly comprising:
a mold configured for forming an ice cube, the mold having a base, a side wall attached to the base, and an opening where the ice cube is dispensed from the mold, the opening spaced from the base;
an auger for removing the ice cube from the mold, the auger having a shaft with a proximal end outside of the mold, a distal end within the mold, and a central section between the distal end and the proximal end and extending through the opening, the auger being sufficiently spaced from the side wall so that the ice cube fauns within the side wall and base, the auger further having a threaded portion configured for moving the formed ice cube out of the mold through the opening via rotation of the auger;
wherein, the mold defines an inner width and the auger defines an outer width, the inner width of the mold being at least twice as large as the inner width of the auger so that the ice cube forms between the mold and the auger;
the mold further includes at least two dividing walls, the at least two dividing walls positioned on the side wall of the mold for forming gaps within the ice cube, the at least two dividing walls extending through the opening of the mold toward the proximal end of the shaft.
2. The ice making assembly of claim 1 , wherein the shaft is sized so that the auger can lift ice cubes upwardly from the mold via the opening.
3. The ice making assembly of claim 2 , wherein the ice cube comprises a first ice cube and the shaft is sized so that the first ice cube can be disposed on the shaft outside of the mold for finishing while a second ice cube is formed in the mold.
4. The ice making assembly of claim 1 , further including an ice cube splitter located outside of the mold configured for splitting the ice cube.
5. The ice making assembly of claim 4 , wherein the ice cube splitter includes a thickened portion of the shaft.
6. The ice making assembly of claim 4 , wherein the ice cube splitter includes a wedge located outside of the side wall.
7. The ice making assembly of claim 6 , wherein the wedge is located on a portion of at least one of the at least two dividing walls extending from within the side walls to outside of the mold.
8. The ice making assembly of claim 6 , wherein the wedge is spaced from at least one of the at least two dividing walls extending from within the side walls to outside of the mold.
9. The ice making assembly of claim 1 , wherein the auger includes a lifting cam at the distal end of the auger for lifting the ice cube from the base of the mold.
10. An ice making assembly comprising:
mold configured for forming an ice cube, the mold having a base, a side wall attached to the base, an opening where the ice cube is dispensed from the mold, the opening spaced from the base, and at least two dividing walls, the at least two dividing walls positioned on the side wall of the mold for forming gaps within the ice cube the at least two dividing walls extending through the opening of the mold toward the proximal end of the shaft;
an auger for removing the ice cube from the mold, the auger having a shaft with a proximal end outside of the mold, a distal end within the mold, and a central section between the distal end and the proximal end and extending through the opening, the auger being sufficiently spaced from the side wall so that the ice cube forms within the side wall and base, the auger further having a threaded portion configured for moving the formed ice cube out of the mold through the opening via rotation of the auger, the shaft having a length between the proximal and distal ends of the shaft, the length of the shaft being sufficient to permit the auger to support a first ice cube outside of the mold adjacent the proximate end of the shaft and a second ice cube within the mold adjacent the distal end of the shaft; and
an ice cube splitter located outside of the mold configured for splitting the ice cube at the gap as the auger moves the ice cube.
11. The ice making assembly of claim 10 , wherein the ice cube splitter includes a thickened portion of the shaft.
12. The ice making assembly of claim 10 , wherein the ice cube splitter includes a wedge located outside of the side wall.
13. The ice making assembly of claim 10 , wherein the auger includes a lifting cam at the distal end of the auger for lifting the ice cube from the base of the mold.
14. A refrigeration appliance comprising:
a refrigerated compartment;
a mold within the refrigerated compartment configured for forming an ice cube, the mold having a base, a side wall formed continuously and unitarily with the base, and an opening where the ice cube is dispensed from the mold, the opening spaced from the base;
an auger having a shaft with a proximal end above and outside of the mold, a distal end within the mold, and a central section between the distal end and the proximal end and extending through the opening, the auger being sufficiently spaced from the side wall so that the ice cube forms within the side wall and base, the auger further having a threaded portion configured for moving the formed ice cube out of the mold through the opening via rotation of the auger; and
a motor located above the mold and attached to the proximal end of the shaft for rotating the auger to lift the ice cube from the mold;
wherein, the mold defines an inner width and the auger defines an outer width, the inner width of the mold being at least twice as large as than the inner width of the auger so that the ice cube forms between the mold and the auger;
the mold further including at least two dividing walls, the at least two dividing walls positioned on the side wall of the mold for forming gaps within the ice cube, the at least two dividing walls extending through the opening of the mold toward the proximal end of the shaft.
15. The refrigeration appliance of claim 14 , further including an ice cube splitter located outside of the mold configured for splitting the ice cube at the gap.
16. The refrigeration appliance of claim 14 , wherein the auger includes a lifting cam at the distal end of the auger for lifting the ice cube from the base of the mold.
