    • A device for sensing a level of ice stored in a bin of an automatic ice maker includes a bail arm and an actuator mechanism. The actuator mechanism is constituted by a shape memory alloy that, upon application of a voltage, contracts to move the bail arm to a raised position prior to initiation of an ice harvest cycle. After completion of the ice harvest cycle, the voltage is discontinued, allowing the shape memory alloy to relax, causing the bail arm to return to a lowered position. The bail arm includes a sensing member that extends into the bin and, depending upon the level of ice, prevents the bail arm from contacting a sensing switch, temporarily halting ice production.
    • 用于感测存储在自动制冰机箱中的冰层的装置包括吊环臂和致动器机构。 致动器机构由形状记忆合金构成,该形状记忆合金在施加电压之后收缩,以便在开始采冰循环之前将吊环移动到升高位置。 完成收冰循环后,中断电压,允许形状记忆合金放松,使吊环臂返回降低位置。 吊环臂包括延伸进仓的传感构件,并且根据冰的水平,防止吊环臂接触传感开关,暂时停止制冰。
