Abstract
Appliances having a detergent dispenser that may be flushed with a water flow for removal of residual treating chemistry while reducing sudsing are disclosed. An example dispenser includes a cup with a bottom wall, a siphon tube projecting upwardly from the bottom wall, a cover for the siphon tube, an opening configured to introduce a liquid stream into the cup from a position above and beyond a periphery of the cover, wherein substantially all of the liquid stream flows downwardly along a trajectory defined by the opening and terminating below and within the periphery of the cover, and wherein the liquid stream directly impinges a portion of at least one of the cup or the siphon tube below the cover.
