    • An ice level sensing system for use on a refrigerator including a freezer compartment having top wall, opposite side walls and an access opening. A door is provided for closing the access opening. An ice maker is disposed within the freezer compartment adjacent the top wall for forming ice pieces. An ice storage bin is removably mounted to the door below the ice maker for receiving ice pieces from the ice maker. An emitter element, supported on a side wall of the freezer, emits a beam of light across the upper portion of the bin. A receiver element, supported on a freezer side wall opposite the emitter element, receives the beam of light wherein beam of light travels between the emitter element and the receiver element along a line of sight path. A paddle is rotatably supported on a freezer side wall for blocking the line of sight when the door is open. In addition, a movable member may be provided, supported on a freezer side wall opposite the paddle, which may be selectively movable between an ON position and an OFF position wherein in the OFF position the movable member blocks the line of sight.
    • 一种用于冰箱的冰水平感测系统,其包括具有顶壁,相对侧壁和进入开口的冷冻室。 提供用于关闭进入开口的门。 制冰机设置在靠近顶壁的冷冻室内,用于形成冰块。 储冰箱可移除地安装在制冰机下面的门上,用于从制冰机接收冰块。 支撑在冷冻室的侧壁上的发射体元件在箱的上部发射出一束光。 支撑在与发射体元件相对的冷冻器侧壁上的接收器元件接收光束,其中光束沿着视线路径在发射器元件和接收器元件之间传播。 桨叶可旋转地支撑在冷冻器侧壁上,用于当门打开时阻挡视线。 此外,可以设置可动构件,支撑在与桨相对的冷冻器侧壁上,该冷冻器侧壁可以在ON位置和OFF位置之间选择性地移动,其中在OFF位置,可动构件阻挡视线。
