A washdown flush toilet patent (Publication Number: US11885109B2) has been granted, detailing a unique design for the water discharge trap conduit connected to the bowl part. The design includes an inlet pipe part, a trap ascending pipe part, and a trap descending pipe part, with specific features such as an enlarged part on the downstream side of the ascending flow channel and a shrunk part at the downstream end of the ascending flow channel. The cross-section perpendicular to the flow direction of the ascending flow channel also features convex upward shapes at central regions, with specific curvatures and widening gaps between surfaces of the enlarged part.
Furthermore, the patent includes additional claims such as the formation of the top surface of the enlarged part by a vertical wall surface, the presence of a second enlarged part on the downstream side of the descending flow channel, and the specific sizing of the shrunk part in relation to the adjacent enlarged part. These claims highlight the intricate design elements of the washdown flush toilet, aiming to optimize the flow of waste and water through the system. The unique features described in the patent aim to improve the efficiency and effectiveness of the toilet's flushing mechanism, potentially offering benefits in terms of water conservation and overall performance.
