Abstract:
A basin for use with a source for supply of potable water thereto and having a spigot for normally passing said potable water into said basin for use and a drain for passing gray water therefrom, the basin being formed with a peripherally-extending wall having an interior surface for confining portions of said water in said basin between said source and said drain, the basin further comprising:an inlet flow channel formed in the interior surface of the basin, separately from said spigot, gravitationally below a top rim of the basin formed on said wall, the inlet flow channel being directed inwardly of the basin and downwardly toward said drain and extending substantially uninterrupted about at least a major portion of said periphery of said interior surface; and a water supply passage conducting potable water between said supply source and said inlet flow channel, said passage being located outwardly of the interior surface of the basin and providing said potable water substantially uniformly to the inlet flow channel for smooth flow therethrough and to create a smoothly-flowing film of water passing from the inlet channel to the drain, which film substantially completely covers the interior surface of the basin beneath said inlet channel and protects and washes said surface of detritus falling toward said surface during use of the basin, wherein said water supply passage extends from a portion of the basin adjacent the drain to the inlet flow channel, wherein said basin also has an exterior surface and the water supply passage extends through the wall of the basin between the interior and the exterior surfaces, and wherein the water supply passage extends through the wall of the basin generally parallel to both the interior wall and the exterior wall of the basin.
