Patent ID: 11473280

Abstract:
A sink that has a self-cleaning basin generally includes a sink basin that is defined by a sink rim, a sink base drain, a sink basin outer surface, a bowl shaped sink basin inner surface, and a plurality of ramped channels recessed in the inner surface located within one inch from the sink rim. Each of the ramped channels is defined by a deep end that essentially evenly ramps to the inner surface at a ramp terminating end. Each of the ramped channels is angled essentially between 0° and 10° with the ramp terminating end further away from the sink rim than a back channel side that is located at the deep end, so that the channels are hidden in an under-mounted sink. Each channel has an aperture located at the back channel side of each of the ramped channels. Each of the apertures is configured to connect with a water line dispenses water through the aperture along the ramped channel and into the sink basin inner surface where the water swirls to clean the sink basin.
