    • In one aspect, a dishwasher having an upper rack wash operation is described. In one example embodiment, the dishwasher comprises a tub, and a fluid circulation assembly for circulating water. The assembly comprises a pump, a lower spray arm, and at least one other spray arm. The at least one other spray arm comprises one of a mid level spray arm and an upper spray arm. The pump is in flow communication with the lower spray arm via a water passage, and the pump is in flow communication with the other spray arm via a conduit that permits water flow around the water passage. The dishwasher further comprises a water flow blocking mechanism comprising a water flow blocking device, a magnet positioned outside the water flow path, and a magnet positioning device coupled to the magnet. The water flow blocking device is normally positioned in a pocket in the conduit. The magnet positioning device is configured to cause the magnet to move from a first position to a second position. When the magnet is in the first position the water flow blocking device is maintained in the pocket by magnetic forces from the magnet. When the magnet is in the second position the water flow blocking device is not retained in the pocket by magnetic forces of the magnet.
    • 在一个方面,描述了具有上架洗涤操作的洗碗机。 在一个示例性实施例中,洗碗机包括桶和用于循环水的流体循环组件。 组件包括泵,下喷臂和至少一个其它喷臂。 所述至少一个其它喷雾臂包括中间喷射臂和上部喷雾臂中的一个。 泵通过水通道与下喷臂相通,泵通过允许水流在水通道周围的管道与另一喷臂相流。 洗碗机还包括水流阻塞机构,其包括水流阻挡装置,位于水流路外部的磁体和耦合到磁体的磁体定位装置。 水流阻塞装置通常位于管道中的口袋中。 磁体定位装置构造成使得磁体从第一位置移动到第二位置。 当磁体处于第一位置时,水流阻塞装置通过磁铁的磁力保持在口袋中。 当磁体处于第二位置时,水流阻塞装置不会通过磁体的磁力保持在口袋中。
