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 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 90° 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 moves over the inner surface to clean the sink basin.

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.
