    • An ice level sensing system for an appliance having a cavity with a cavity wall. An ice storage bin and an ice maker are disposed within the cavity. The ice storage bin is configured to hold ice discharged from the ice maker. The ice level sensing system includes a transmitter for transmitting a light beam and a detector for detecting the light beam. The transmitter and the detector are disposed on the cavity wall. A reflector is disposed relatively remote from the transmitter. The transmitter is operative to project the light beam toward the reflector. The transmitter and the detector are angled relative to each other so that the light beam reflected by the reflector is directed toward the detector.
    • 一种用于具有具有空腔壁的空腔的器具的冰水平感测系统。 一个储冰箱和一个制冰机设置在空腔内。 储冰箱被配置成保持从制冰机排出的冰。 冰水平感测系统包括用于发射光束的发射器和用于检测光束的检测器。 发射器和检测器设置在腔壁上。 反射器设置成相对远离发射器。 发射器可操作以将光束投射到反射器。 发射器和检测器相对于彼此成角度,使得由反射器反射的光束被引向检测器。
