Dual-flow rate rim spout for flush toilet
The patent application (Publication Number: US20240035267A1) describes a flush toilet design with innovative features aimed at improving efficiency and performance. The toilet includes a bowl portion for waste reception, a trap portion for waste discharge, a main conduit for washing water flow, a rim communication hole, a rim conduit, and a rim spout. The unique aspect of this design is the inclusion of a low-flow rate spout and a high-flow rate spout within the same flow path, with the low-flow rate spout having a smaller cross-sectional area than the high-flow rate spout. Additionally, the rim conduit features an agitation chamber and a continuous expansion of the flow-path cross-sectional area from the low-flow rate spout towards the high-flow rate spout.
Furthermore, the flush toilet design incorporates a jet conduit, a jet spout for directing washing water towards the trap portion, and a pressure-rate control portion. The pressure-rate control portion is strategically positioned to regulate the flow of washing water between the main conduit and the rim conduit. The design also includes specific features such as contracted portions in the jet conduit, acute angles between surfaces, and gradual narrowing towards the jet spout. Additionally, the mounting portion of the toilet is designed with varying wall thicknesses and mounting hole configurations for secure installation on a wall surface. The inclusion of a drain socket, drain flange portion, and modesty panel further enhances the functionality and aesthetics of the flush toilet.
