摘要： The dishwasher of the present invention is adapted to skip a drain cycle if the water in the dishwasher is clean enough. The invention uses a turbidity sensor to sense the turbidity of the water. If the sensed turbidity is below a threshold value, the drain motor and the water valve are disabled to prevent the water from being drained and to prevent additional water from being introduced into the dishwasher.
摘要翻译：如果洗碗机中的水足够干净，则本发明的洗碗机适于跳过排水循环。本发明使用浊度传感器来感测水的浊度。如果感测到的浊度低于阈值，则禁用排水马达和水阀以防止水被排出并防止额外的水被引入洗碗机。

摘要： A dishwasher includes a pump assembly having a chopper blade and apertured plate arrangement which function to chop soil particles entrained in a flow of washing fluid. The chopper blade floats or axially slides relative to a drive member from a first position spaced from the apertured plate to a second position closer to the apertured plate in order to macerate the soil particles. The chopper blade is actually mounted to a hub member including a shaft portion that extends into and abuts an inner portion of an impeller to maintain a desired spacing between the chopper blade and the apertured plate, while transferring drive from the drive member to both the chopper blade and impeller.
摘要翻译：一种洗碗机包括具有切割刀片和多孔板装置的泵组件，其功能是切割夹带在洗涤流体中的土壤颗粒。切碎刀片相对于驱动构件从与多孔板间隔开的第一位置浮动或轴向滑动到靠近多孔板的第二位置，以使土壤颗粒浸没。切割刀片实际上安装在轮毂件上，轮毂件包括轴部分，该轴部分延伸到叶轮的内部并邻接叶轮的内部，以在切割刀片和带孔板之间保持期望的间隔，同时将驱动部件从驱动部件转移到两个切碎机叶片和叶轮。

摘要： A dishwasher includes a frontal frame, a tub having a plurality of walls collectively define a washing chamber, and a door pivotally mounted to the frontal frame for sealing the washing chamber. During a washing operation, sound generated by operation of a mechanical pump escapes from below the dishwasher. To minimize sound from escaping and to provide a more enjoyable environment, a sound sealing system is mounted at a bottom portion of the dishwasher door. The sound seal system includes a sound tray that extends across the frontal frame below a bottom edge portion of the door. The sound tray can be directly, pivotally attached to the door, or an additional flexible seal is employed to span and seal a gap between the sound tray and the bottom portion of the door.
摘要翻译：洗碗机包括正面框架，具有共同限定洗涤室的多个壁的桶以及可枢转地安装在正面框架上用于密封洗涤室的门。在洗涤操作期间，通过机械泵的操作产生的声音从洗碗机的下方逸出。为了最大限度地减少声音泄漏并提供更愉快的环境，在洗碗机门的底部安装有声音密封系统。声音密封系统包括在门的底部边缘部分下方延伸穿过正面框架的声音托盘。声音托盘可以直接地，可枢转地附接到门上，或者使用附加的柔性密封件来跨越和密封声盘和门的底部之间的间隙。
