In this embodiment, the water guiding groove 4 runs through the front portion of the urinal 1, two ends of the water guiding groove 4 are respectively located at the left and right sides of the urinal 1, and a distance L1 between one end of the water guiding groove 4 and the rear portion of the urinal 1 in the front-rear direction is smaller than a distance L2 between the other end of the water guiding groove 4 and the rear portion of the urinal 1 in the front-rear direction, as shown in fig. 5. Specifically, one end of the water guide groove 4 is close to the rear part of the urinal 1, and an included angle between a horizontal connecting line between the intersection point of the water guide groove 4 and the water guide table 5 and the midpoint of the rear part of the urinal 1 and a horizontal center line of the toilet body 10 in the front-rear direction is 20 to 45 degrees, as shown in fig. 5, and an optimal interval is 20 to 30 degrees.

In this embodiment, a portion of the water blocking top wall 43 close to and receiving the second side wall 52 of the water guide platform 5 is a first gradually-changing section 431, and a width of the first gradually-changing section 431 is gradually reduced along a flowing direction of the water flow in the water guide groove 4, so that the appearance of the toilet body 10 is more beautiful.

In this embodiment, an included angle formed by a connection line between two ends of the first transition section 431 and a midpoint of the rear portion of the urinal 1 is 10 to 20 °, and a width of the water blocking top wall 43 excluding the first transition section 431 is greater than 10mm. The area 432 with the largest width of the water retaining top wall and the first transition section 431 are respectively positioned at the left side and the right side of the urinal 1, and the connecting line between the area 432 with the largest width of the water retaining top wall and the middle point at the rear part of the urinal 1 forms an included angle of 10 degrees to 20 degrees, as shown in fig. 5.

In this embodiment, a portion of the second bottom wall 51 close to and receiving one end of the water chute 4 is set as a second transition section, and a width of the second transition section is gradually reduced along a flowing direction of the water flow in the water guide platform 5.

In this embodiment, the longitudinal section of the water chute 4 is C-shaped, and the longitudinal section of the water guide platform 5 is L-shaped.

In this embodiment, a jet orifice 6 is arranged at the bottom of the urinal 1 at the side opposite to the inlet of the sewage pipe 2. The closestool body 10 is of a water tank-free structure, the cleaning opening 3 and/or the jet opening 6 are/is connected with a normal-pressure water source, and the normal-pressure water source is a municipal water supply source.

The utility model discloses a closestool, its washing process who washes clean mouth 3 is as follows:

in the first stage, as shown in fig. 6, the water jet from the washing port 3 moves linearly (linearly in plan view, and parabolically in front view) until it hits the first side wall 42 of the water chute 4, and the hit area is the periphery of the intersection point of the center line of the water outlet of the wash ring and the first side wall 42 of the water chute 4. Due to the high flow velocity, the impinging water stream quickly spreads in three directions, namely, forward, up and down, against the first sidewall 42. The upwardly diverging water stream, by virtue of still having a forward component velocity, has a tendency to fly off the pan surface in the region downstream of the point of impact (i.e., the region 432 where the width of the top wall of the water dam is greatest). Since the water flow has hardly lost energy for a long time after flowing out of the washing port 3, the tendency to fly out of the pan surface is strong, so that this region becomes the region where water splashing occurs most easily. The water retaining top wall 43 of the water chute 4 starts to play a role of blocking water flow, and the water retaining top wall 43 has the largest width in the downstream area of the impact point, so that the water flow can be effectively blocked, and the water flow is prevented from splashing outwards.

In the second stage, as shown in fig. 7, the water flows to the front of the pan surface, and due to the high curvature of the front of the pan surface, the water flow, under centrifugal force, tends to approach the first side wall 42 and climb along the first side wall 42 against gravity. Because the water retaining top wall 43 of the water chute 4 above the front part of the pan surface reaches a certain width (> 10 mm), water flow can be effectively blocked and the water retaining top wall is prevented from splashing.

In the third stage, as shown in fig. 8, the water flow crosses the midpoint of the front of the pan surface and the curvature decreases as it flows forward. Proceeding to a position of about 15 deg. -45 deg., the tendency of the water stream to splash begins to disappear and even to leave the first side wall 42 of the flume 4 under multiple factors. These factors include the low curvature of the area, the convergence of the slope of the pan surface toward the center of the pan surface under the force of gravity, the loss of capacity after a distance of flow resulting in a reduction in velocity, etc. Because the water flow has no splashing tendency and does not need the water retaining top wall 43 to retain water, the water retaining top wall 43 in the area is set as the first gradual change section 431, so that the C-shaped structure is gradually transited to the L-shaped structure, and finally, the C-shaped structure is completely changed into the L-shaped water guide platform 5 and is kept to the cleaning opening 3.

In the fourth stage, as shown in fig. 9, the water flows to the rear part of the pan surface, which has a large curvature, so that the water still on the water guide table 5 starts to flow against the second side wall 52 again. Because the water continuously gathers to the center under the action of gravity, the water quantity remained on the water guide platform 5 is greatly reduced. Also, because of the energy loss caused by the flow process, the flow rate of only a small amount of water remaining on the water guide table 5 has been reduced. Therefore, even if the curvature is large, the water flow does not have the capability of splashing outwards, and even if the area is L-shaped, the water flow cannot splash.

In the fifth stage, as shown in fig. 10, the water flow returns to the cleaning port 3 and is converged with the water flow sprayed from the cleaning port 3 to wash the pot surface together.

The utility model discloses a toilet, its water guide structure includes guiding gutter 4 and water guide platform 5 utilize guiding gutter 4's manger plate roof 43 to shelter from the rivers of 3 preceding stages of water that go out of washing mouth, avoid the rivers outwards to splash, and the rivers in 3 play water later stages of washing mouth are not enough outwards to splash, therefore adopt the 5 water conservancy diversion of water guide platform to the performance is led 5 outward appearances and is pleasing to the eye, succinct, the clean advantage of managing of being convenient for.

The utility model discloses a closestool, the part that does not relate to all is the same with prior art or can adopt prior art to realize.

The above embodiments are only used to further illustrate the toilet of the present invention, but the present invention is not limited to the embodiments, and any simple modifications, equivalent changes and modifications made to the above embodiments by the technical essence of the present invention all fall into the protection scope of the technical solution of the present invention.
