In the following description, a lateral section refers to a section of the toilet bowl in a horizontal direction in a normal use state, and a longitudinal section refers to a section of the toilet bowl in a vertical direction in a normal use state.
The upper opening of the basin part 1 is provided with an egg-shaped flange 11, and the egg-shaped flange 11 is suspended inwards, so that water flow can be effectively prevented from splashing outside the toilet. The tub portion 1 has a drying surface 12 and a water storage surface 13 formed continuously with the drying surface 12. The dry surface 12 includes an inner concave water-bearing layer 121 connected to the egg-shaped flange 11 and an outer convex water-dividing layer 122 formed continuously with the inner concave water-bearing layer 121.
The running water is through the guiding effect of indent water-bearing layer 121 and evagination water-dividing layer 122, and the rivers that come out from the water supply unit are fan-shaped to diverge in the flow in-process, constantly increase the water area, not only can make full use of the kinetic energy of original water to clean dirt-bearing surface, when dirt-bearing surface glues thin thick thing, also can guarantee the scrubbing effect.
The water supply device 2 is connected with a pressurized tap water pipeline. The water supply device 2 includes a surface flushing water outlet 21 provided in the concave water receiving layer 121 and configured to discharge the washing water in a substantially horizontal direction along an inner peripheral surface of the concave water receiving layer 121 to form a swirling flow. The concave water-receiving layer 121 and the convex water-dividing layer 122 are jointly formed into water-guiding layers which continuously disperse in a fan shape and gather all around the washing water from the water-flushing outlet 21.
As shown in fig. 6, the tub portion 1 has a symmetrical structure on the front side and both sides with respect to the Y axis, and an asymmetrical structure on the rear side. The left and right lateral cross-sectional area radius of the egg-shaped flange 11 is defined as R1, the front lateral cross-sectional area radius is defined as R2, the rear right lateral cross-sectional area radius is defined as R3, and the rear left lateral cross-sectional area radius is defined as R4, then R1> R3> R2> R4.
As shown in fig. 7 to 9, the boundary between the concave water-receiving layer 121 and the convex water-dividing layer 122 on the X axis is substantially configured such that the outer edge portion of the wash water flow ejected from the face-flushing water outlet 21 reaches the intersection of the X axis. The radius of curvature of the boundary portion longitudinal section of the concave water-bearing layer 121 and the convex water-dividing layer 122 in the positive and negative directions of the X-axis is defined as ρ1, the radius of curvature of the longitudinal section of the intersection point of the constant-height surface at the point of ρ1 in the basin in the negative direction of the Y-axis is defined as ρ3, the radius of curvature of the longitudinal section of the intersection point in the positive direction is defined as ρ5, and the radii of curvature of the longitudinal section of the intersection point of the region A1 and the region A3 are defined as ρ2 and ρ4, respectively, ρ1< ρ2< ρ3, and ρ1< ρ4< ρ5.

The swirling water in the sump 31 rapidly generates a siphon phenomenon by utilizing the swirling kinetic energy of the water and the high-speed water injected through the injection hole 34, thereby completing the sewage discharge operation.
As shown in fig. 10A and 10B, under the action of the water guiding surface constructed as described above, water flow starts to diverge in the area A1, the pan surface is washed by the fan-shaped surface, and the water still can maintain a large kinetic energy after passing through the curvature area A2 of the contraction section due to the slow speed of the water flow.
As shown in fig. 10C and 10D, after the water flow passes through the R2 section, the water flow flows to the area A3 along the tangential direction under the action of centrifugal force, and simultaneously diverges from the area A3, the pan surface is washed by the fan-shaped surface, and the water still can maintain larger kinetic energy after passing through the curvature area A4 of the contraction section due to the delay of the water flow speed. The end of the outer convex water-dividing layer 122 of the water outlet is flushed on the adjacent surface, vortex water is pressed down by the action of reducing the curvature radius, so that the vortex water flows towards the water storage pit 31, and the high-speed water of the water outlet 21 is prevented from being flushed on the low-speed water blocking surface of the end of the vortex, so that splash is caused.
As a preferred embodiment, as shown in FIG. 3, the slopes of the concave water-bearing layer 121, the convex water-bearing layer 122 and the water-storing layer 13 are set to be a, b and c respectively, so that b > c > a is required to be satisfied.
The structure adopts a flushing mode of tap water, and the kinetic energy of the original pipeline water is utilized to flush the basin surface, so that the cleaning effect is obviously better than that of the existing cleaning mode of water storage through a water tank, and the structure has lower requirements on the production and manufacturing precision of the pipeline and stronger adaptability.
The structure adopts the egg-shaped flange 11 which is suspended inwards to replace the water guide ring of the traditional closestool structure, so that the dirt is not easy to remain and the cleaning is easier.
The structure can increase the contact area of water collected at the rear end of the basin 1 by moving forward the water storage pit 31 (positioned at the front end of the center line of the egg-shaped flange 11), and raise the water level when the vortex water flows through the rear end of the basin 1, thereby reducing the waste of water before siphon and keeping the kinetic energy of water. Secondly, the water storage pit 31 moves forward to enable the siphon pipeline to move forward integrally, so that the overall size of the ceramic can be greatly reduced, the ceramic is beneficial to miniaturization and light-weight production, and meanwhile, when the ceramic is used, people can sit more backwards, and splash is prevented from being splashed more sanitary.
The design of the water guide surface of the basin part 1 with the structure ensures that the vortex water flow on the basin surface has no flow break phenomenon and water flying, and drives the water in the basin part to rotate through the vortex water effect, so that the original water kinetic energy is reserved while the water potential energy is increased on the lifting liquid level surface, and the basin is more beneficial to flushing.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereto, and any modifications and equivalent substitutions made on the basis of the technical scheme according to the technical idea of the present invention fall within the protection scope of the present invention.
