Patent number: 11987969Abstract: A toilet assembly includes a toilet body and a fluidic oscillator. The toilet body defines a toilet bowl that is configured to receive a volume of fluid therein. The fluidic oscillator is coupled to the toilet body in a rim area of the toilet bowl. The fluidic oscillator is positioned to direct a fluid onto an inner surface of the toilet bowl. The fluidic oscillator is configured to continuously redirect the flow of fluid to different locations along the inner surface of the toilet bowl.Type: GrantFiled: May 18, 2023Date of Patent: May 21, 2024Assignee: Kohler Co.Inventors: Clayton C. Garrels, William C. Kuru, William Kalk, Randal S. Graskamp

Publication number: 20240093473Abstract: An educator assembly for a toilet includes a suction reservoir, a flow driving device, a first nozzle, a second nozzle, and a discharge outlet. The suction reservoir is configured to store a supply of water. The flow driving device is configured to supply a flow of water to the eductor assembly and in fluid communication with the suction reservoir to create a suction port proximate to the flow driving device and the suction reservoir. The first nozzle is at the end of the flow driving device. The second nozzle is downstream of the suction port. The discharge outlet is coupled to a trapway of the toilet and configured to receive discharge from the second nozzle downstream of the suction port.Type: ApplicationFiled: November 29, 2023Publication date: March 21, 2024Inventors: Clayton C. Garrels, Jeremiah J. Rauwerdink, Randal S. Graskamp

Publication number: 20230358028Abstract: A toilet includes a bowl with a sump and a trapway connecting the sump to an outlet of the toilet. The trapway has a zeta shape and is configured to induce a siphon which provides pressure to suction waste water from the bowl during a flush cycle. A trapway supply conduit is connected to the trapway in a tangential orientation to an upleg region of the trapway. The trapway supply conduit supplies water to the trapway, which follows a contour of the inner surface of the trapway supply conduit and continues in the same direction into the upleg region of the trapway by relying on a fluid flow to follow the curve of a convex surface placed proximate to the flow.Type: ApplicationFiled: July 12, 2023Publication date: November 9, 2023Inventors: Clayton C. Garrels, Jeremiah J. Rauwerdink, Randal S. Graskamp
