appliance 10 provides ice to thecontainer 20. In some embodiments, the ice is soft ice, such as, but not limited to, nugget ice, pellet ice, or chewable ice. Ice egresses thecontainer 20 into theice processing device 100. For instance, ice may egress from thecontainer 20 through thechannel 204 at thedrive unit 200 through the inlet opening 106 into theice processing chamber 108 at theice processing device 100. In still some embodiments, ice may egress directly from thecontainer 20 through the inlet opening 106 into theice processing chamber 108. Theauger drive shaft 104 receives a motive force or torque (e.g., from the appliance 10) to rotate theauger 120. Theauger blade 124 moves the ice from thetop portion 126 toward thebottom portion 128, such as in a helical or spiral configuration. The conical or frustoconical extension of theauger wall 122 pushes the ice toward an ice crushing surface (e.g., raised surfaces) at the firstinner wall 112 at thefirst processing zone 101. Theauger wall 122 further pushes, mashes, or squeezes the crushed ice toward the secondinner wall 114 at thesecond processing zone 102. The slush or mashed ice egresses from thesecond processing zone 102 through theoutlet opening 116. - Some embodiments of the
appliance 100 and ice described herein may form or generate soft ice. For instance, nugget, pellet, chewable, or other soft icemaking appliances may contrast with other icemaking devices (e.g., refrigerator appliances), such as by an absence of trays of water configured to retain water until ice is frozen. One skilled in the art will appreciate that such differences in structure of ice may patentably separate soft ice, soft icemaking appliances, and ice processing devices from other icemaking and ice processing devices. - 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.
