Abstract: A sink that includes a door that is positioned to visually obscure the drain, wherein the door can be opened by the user to access the drain when needed. The door includes a door adjustment mechanism that can allow for the door to be opened by a user and then held open without requiring user intervention. The door adjustment mechanism can also be configured to release the door and allow it to close through the actions of the user. In one or more examples, the door can be positioned so that a gap exists between an edge of the door and a basin portion of the sink. The gap can be large enough to allow for water to flow from the basin of the sink to the drain, but small enough to allow for the drain to be visually obscured.

Abstract: Systems, methods, and techniques for cleaning sinks and dishes are provided. In some embodiments, a cleaning system comprises at least one fluid supply, at least one opening in a side wall of a sink basin, and at least one nozzle positioned along an exterior of the sink basin. The nozzle is configured to receive fluid from the fluid supply, and dispense fluid through an opening in a side wall of the sink basin to an interior surface of the sink basin. In some embodiments, the nozzle is configured to dispense fluid to the interior of a sink basin, such that substantially all surfaces of the interior of the sink basin are covered with a thin layer of fluid. In some embodiments, nozzle dispensing angle, duration of a cleaning cycle, flow rate or amount of dispensing fluid, or activation of a cleaning cycle may be manually or automatically controlled.

Abstract: A microfluidic oscillator nozzle, comprising a nozzle body comprising an exterior surface; an interior surface defining a three-dimensional space therein; a fluid inlet; and a fluid outlet, wherein the three-dimensional space, the fluid inlet, and the fluid outlet are inflow communication, the three-dimensional space comprises a first fluid interaction region fluidly coupled to a first pair of feedback flow paths, and wherein a largest nozzle dimension is less than about 20.0 mm.
