    • An ice maker for a refrigerator/freezer having a control module for more reliably driving a rotatable ice ejector for removing ice bodies from a mold of the ice maker and for refilling mold cavities with water. The control module has an ice ejector drive with a drive coupling that includes a gear wheel and an ejector shaft section, both made of hard plastic material, preferably a polymide resin, for transmitting higher torque to the rotary ice ejector without failure of the plastic drive components. In one embodiment, a drive sleeve on the gear wheel and a drive shaft section have a spline coupling for more effectively distributing driving forces in the drive coupling. In another embodiment, a metallic collar is tightly positioned over the gear wheel sleeve for enhancing torque transmission in the drive coupling. The control module further is operable for refilling the ice maker mold cavities to a predetermined level during each cycle of operation notwithstanding slight alterations in positioning of water fill switching contact due to manufacturing tolerances or forces to which the ice maker is subjected during shipping, handling or installation.
    • 一种用于冰箱/冷冻机的制冰机,具有用于更可靠地驱动可旋转的冰喷射器的控制模块,用于从制冰机的模具中除去冰体并用水重新填充模腔。 该控制模块具有一个具有驱动联轴器的驱动联轴器的驱动联轴器,该驱动联轴器包括齿轮和推出轴部分,两者均由硬塑料材料制成,优选为聚酰亚胺树脂,用于将更高扭矩传递到旋转式冰喷射器,而不会损坏塑料驱动 组件。 在一个实施例中,齿轮上的驱动套筒和驱动轴部分具有用于更有效地分配驱动联接器中的驱动力的花键联接件。 在另一个实施例中,金属套环紧紧地定位在齿轮套上方,以增强驱动联轴器中的转矩传递。 控制模块还可操作用于在每个操作周期期间将制冰机模具腔重新填充到预定水平,尽管由于在运输,处理或制造过程中制冰机遭受的制造公差或力,水填充开关触点的定位略有改变 安装。
