WIPO Patent Application WO/2023/213003
Kind Code:
A1
Abstract:
A washdown siphonic sewage discharge structure and a toilet. The sewage discharge structure comprises a toilet (1) and a siphon bend (2), wherein the bottom of the toilet (1) is provided with a sewage discharge outlet (11); the siphon bend (2) comprises a sewage inlet section (21), a buffer section (22), a turning section (23) and a sewage discharge section (24), which are in communication with each other in sequence; the sewage inlet section (21) is in communication with the sewage discharge outlet (11), the sewage inlet section (21) is provided with a sewage inlet (211) and a shallow water platform (212), which are below the sewage discharge outlet (11), and the shallow water platform is in smooth transition with a front edge portion of the sewage inlet (211); the end of the sewage inlet section (21) connected to the buffer section (22) is arranged obliquely backwards and downwards, the buffer section (22) is arranged obliquely backwards and upwards and forms a trap in smooth transition with the sewage inlet section (21), and a water seal level of the trap is located above the shallow water platform (212); the transverse width of the cross section of each part of the buffer section (22) is greater than the longitudinal width thereof, and the cross-sectional area of the buffer section (22) gradually decreases in a sewage discharge direction; and the end of the sewage discharge section (24) away from the turning section (23) extends forwards and downwards, and the cross-sectional area of the end of the sewage discharge section (24) close to the turning section (23) is greater than that of the end of the sewage discharge section (24). The washdown siphonic sewage discharge structure can quickly wash away sewage, is water-saving and noiseless, and has a good deodorization effect.
