Abstract
An ice maker includes a mold and an auger. The mold has at least one cavity with a bottom surface, and is configured for containing water therein for freezing into ice. The auger has a shaft with at least one flight attached thereto, the shaft including a top end and a base end with the base end being rotatably mounted in the bottom surface of the at least one mold cavity. The shaft extends substantially vertically through the mold cavity and is configured to rotate and thereby push the ice out of the mold cavity. The shaft and/or at least one flight has an inward taper in a direction heading from the base end to the top end of the shaft.
