Patent attributes
An ice maker includes an ice mold having an inner surface and an outer surface. The inner surface of the ice mold is configured to retain water for forming ice cubes in the ice mold. The ice mold includes a plurality of ice lobes each shaped to form a respective ice cube in the ice mold. A heater assembly is positioned on the outer surface of the ice mold. In some embodiments, each of a plurality of heating elements of the heater assembly is aligned with a corresponding lobe of the plurality of lobes for supplying heat to ice cubes formed in the lobes for releasing the ice cubes from the ice mold. In some embodiments, the heater assembly includes a heater having a ceramic substrate and one or more electrically resistive traces and electrically conductive traces thick film printed on the ceramic substrate.
