Description

TECHNICAL FIELD

[0001] The present application relates to the field of bathroom, in particular to a flushing toilet and a flushing method. BACKGROUND

[0002] The conventional intelligent toilet, see Figure 1 , a water guide ring and a washing ring water outlet 1 are arranged on the upper part of the pot surface, the water guide ring surrounds the pot surface and its bottom is a water guide platform 2 for guiding water flow. The washing ring water outlet 1 is usually arranged at the back of one side of the pot surface and sprays water towards the water guide ring. The intelligent toilet with the above structure has a poor effect when flushing the washing ring.

[0003] For example, the water tankless toilet directly flushes by using the water pressure of tap water, which has the characteristics of energy saving and beauty. The water tankless toilet usually adopts a small-diameter washing ring water outlet, and the water flow sprayed by the washing ring water outlet is small in flow rate but large in flow speed, which ensures that the water flow can rotate around the water guide ring at low pressure, see Figure 1 . Taking a common 8.5mm nozzle as an example, the flow rate is only about 12L / min at low pressure, but the flow speed can reach 3.5m / s. Due to the large flow speed, the water flow can easily rotate around the pot surface and form a rotating flow 3.

[0004] However, see Figures 2-3 , the water tankless toilet has the following problems:

[0005] (1) Due to the small flow rate, the water flow cannot completely cover the pot surface, and the water flow is unevenly distributed.

[0006] (2) The curvature of the left and right sides of the toilet is small, and the centrifugal force of the rotating water flow is small, so more water flows down from the two sides of the pot surface; the curvature of the front and rear parts of the toilet is large, and the centrifugal force of the rotating water flow is large, so less water flows down from the front or rear part of the pot surface, resulting in a large area of water flow with a very thin water layer on the front and rear parts of the pot surface, especially the middle positions of the water guide platform and the water seal surface, where the water layer is thinnest, such as positions A and B. Due to the surface tension of water, the surface tension tends to make the water shrink and gather. When the water layer is thin to a certain extent, it cannot exist stably and will be broken by slight disturbance, and the broken edge will quickly shrink under the action of surface tension, thereby forming a blind area, such as position A in the figure.

[0007] (3) The water flow flowing down from the water guide platform is often quickly injected into the water seal, and the flushing path before being injected into the water seal is very short. SUMMARY

[0008] The main purpose of the present application is to overcome the defects of uneven distribution of flushing water flow and existence of blind area in the existing flushing toilet, and to provide a flushing toilet and a flushing method, which can uniformly distribute the flushing water flow, avoid the occurrence of flushing blind area, and have good flushing effect.

[0011] Preferably, the height of the second water guide platform is the average of the height of the first water guide platform and the height of the water seal surface.

[0012] Preferably, the included angle between the second water guide platform of the front part of the pan surface and the horizontal plane is smaller than the included angle between the second water guide platform of the rear part of the pan surface and the horizontal plane.

[0013] Preferably, the included angle between the second water guide platform of the front part of the pan surface and the horizontal plane is 10-20 degrees, and the included angle between the second water guide platform of the rear part of the pan surface and the horizontal plane is 35-55 degrees.

[0016] Preferably, the width of the second water guide platform of the front part of the pan surface in the horizontal direction is 25-45 mm, and the width of the second water guide platform of the rear part of the pan surface in the horizontal direction is 10-20 mm.

[0017] Preferably, the width of the second water guide platform in the horizontal direction gradually decreases from the front part of the pan surface to the rear part of the pan surface.

[0018] A flushing method of a flushing toilet, characterized in that a second water guide platform is added between the first water guide platform of the water guide ring and the water seal surface, the second water guide platform is extended along the circumference of the pan surface and is connected at the head and tail; after the flushing ring water outlet sprays flushing water towards the water guide ring, the flushing water flows along the first water guide platform to form a first circulation, the water of the first circulation gradually flows towards the second water guide platform to clean the first wall surface between the first water guide platform and the second water guide platform, then a second circulation is formed at the second water guide platform, and the second circulation gradually flows towards the water seal surface to clean the second wall surface between the second water guide platform and the water seal surface and then injects into the water seal surface.

[0019] Preferably, the water flow in the first circulation on one side of the pot surface flows along the circumference of the pot surface towards the front of the pot surface after flowing into the second water guide platform, and the water flow in the first circulation on the other side of the pot surface flows along the circumference of the pot surface towards the back of the pot surface after flowing into the second water guide platform.

DETAILED DESCRIPTION

[0038] The present application will be further described in the following specific embodiments.

[0039] The terms "first", "second", etc. appearing in the present application are only for the convenience of description, to distinguish different components with the same name, and do not represent the sequence or primary and secondary relationship.

[0040] In the description of the present application, the directions or positional relationships indicated by "up", "down", "left", "right", "front" and "back" are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application, and do not indicate or imply that the devices referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the scope of protection of the present application.

[0041] Referring to Figures 4 to 11A flushing toilet comprises a toilet body 10 provided with a bowl 11 and a sewer pipe 12, etc. The toilet body 10 can further comprise other necessary components, such as a flushing assembly, etc. not shown in the figure. The bowl 11 is provided with a water guide ring 20 and a rim outlet 30, etc. on the wall surface thereof. The water guide ring 20 can be located at a position close to the top of the bowl 11 and extends along the circumference of the bowl 11 and can be connected at its ends. The water guide ring 20 comprises a side portion 21, a bottom portion and a top portion 23. The top portion 23 is raised relative to the wall surface to serve as a water retaining portion. The bottom portion is provided with a first water guide platform 22 which can be a platform with a certain slope to ensure that the flushing water can stay for a period of time when flowing. The rim outlet 30 is located at the side edge of the rear portion of the bowl 11. The rim outlet 30 can discharge water towards the water guide ring 20. The first water guide platform 22 can guide the flushing water to form a first circular flow 13.

[0042] The present application further provides a second water guide platform 24 on the bowl 11. The second water guide platform 24 is located between the first water guide platform 22 and a water seal surface 15 of the bowl 11. The water seal surface 15 of the bowl 11 depends on the arrangement of the sewer pipe 12 in the toilet body 10. The second water guide platform 24 extends along the circumference of the bowl 11 and is connected at its ends. The height of the second water guide platform 24 is the average of the height of the first water guide platform 22 and the height of the water seal surface 15. The water of the first circular flow 13 gradually flows down to the second water guide platform 24 to form a second circular flow 14. The height of the second water guide platform 24, the height of the first water guide platform 22 and the height of the water seal surface 15 refer to the height in the direction perpendicular to the horizontal plane.

[0043] The second water guide platform 24 of the present application divides the wall surface between the first water guide platform 22 and the water seal surface 15 of the bowl 11 into a first wall surface 25 and a second wall surface 26. The wall surface between the first water guide platform 22 and the second water guide platform 24 is the first wall surface 25. The wall surface between the second water guide platform 24 and the water seal surface 15 is the second wall surface 26. The first wall surface 25 and the second wall surface 26 have a large angle with the horizontal plane, i.e. a steep slope. The flushing water is easy to flow downwards on the first wall surface 25 and the second wall surface 26. Therefore, the flushing water stays for a very short time and travels a short distance in the area of the first wall surface 25 and the second wall surface 26. The first water guide platform 22 and the second water guide platform 24 are platforms with a certain slope. They have a small angle with the horizontal plane, i.e. a gentle slope. The flushing water is not easy to flow downwards on the first water guide platform 22 and the second water guide platform 24 relative to other wall surfaces. Therefore, the flushing water stays for a very long time and can travel a long distance in the area of the first water guide platform 22 and the second water guide platform 24.

[0044] Since the second circular flow 14 is approximately located at the intermediate position between the first circular flow 13 and the water seal surface 15, the first wall surface 25 and the second wall surface 26 become two ring-shaped curved surfaces with very small width. No matter the first wall surface 25 or the second wall surface 26, the water flow adjacent to them is abundant. Therefore, the two curved surfaces do not have a very thin water film area and are not easy to have a blind area.

[0045] Further, the included angle a1 between the second water guide platform 24 in the front part of the bowl surface 11 and the horizontal plane is smaller than the included angle a2 between the second water guide platform 24 in the rear part of the bowl surface 11 and the horizontal plane. And the included angle between the second water guide platform 24 and the horizontal plane gradually increases from the front part of the bowl surface 11 to the rear part of the bowl surface 11, that is, the included angle between the second water guide platform 24 and the horizontal plane gradually increases from one side of the front part of the bowl surface 11 to the rear part of the bowl surface 11, and gradually increases from the other side of the front part of the bowl surface 11 to the rear part of the bowl surface 11. In practical application, the included angle a1 between the second water guide platform 24 in the front part of the bowl surface 11 and the horizontal plane is 10-20 degrees. The included angle a2 between the second water guide platform 24 in the rear part of the bowl surface 11 and the horizontal plane is 35-55 degrees, and the specific value can be set according to actual conditions.

[0046] Further, the width b1 of the second water guide platform 24 in the horizontal direction in the front part of the bowl surface 11 is greater than the width b2 of the second water guide platform 24 in the horizontal direction in the rear part of the bowl surface 11. The width of the second water guide platform 24 in the horizontal direction gradually decreases from the front part of the bowl surface 11 to the rear part of the bowl surface 11, that is, the width of the second water guide platform 24 in the horizontal direction gradually decreases from one side of the front part of the bowl surface 11 to the rear part of the bowl surface 11, and gradually decreases from the other side of the front part of the bowl surface 11 to the rear part of the bowl surface 11. In practical application, the width b1 of the second water guide platform 24 in the horizontal direction in the front part of the bowl surface 11 is 25-45 mm, and the width b2 of the second water guide platform 24 in the horizontal direction in the rear part of the bowl surface 11 is 10-20 mm, and the specific value can be set according to actual conditions.

[0047] In the present application, the included angle between the second water guide platform 24 and the horizontal plane is set to be the smallest and the horizontal width is set to be the largest in the front part of the bowl surface 11 where the blind area is most likely to occur, which is beneficial to the water flow on the second water guide platform 24 and realizes longer flushing in the front part of the bowl surface 11, and is more beneficial to eliminate the blind area that is prone to occur here. In addition, because the overall wall surface of the bowl surface 11 is set to have small slope in the front part and large slope in the rear part, and large horizontal width in the front part and small horizontal width in the rear part. Therefore, the included angle between the second water guide platform 24 and the horizontal plane is the smallest in the front part of the bowl surface 11, the largest in the rear part, and the rest is between the two and gradually transitions; the width of the second water guide platform 24 in the horizontal direction is the largest in the front part of the bowl surface 11, the smallest in the rear part, and the rest is between the two and gradually transitions, which conforms to the shape characteristics of the bowl surface 11 itself, the second water guide platform 24 does not look conspicuous, and the overall bowl surface 11 is coordinated and beautiful.

[0048] Based on this, the present application further provides a flushing method for flushing a toilet, which is implemented by using the flushing toilet described above, and includes the following steps.

[0049] Referring to Figure 10After the washing water is sprayed from the washing ring outlet 30 towards the water guide ring 20, the washing water flows along the first water guide platform 22 to form the first ring flow 13, the water of the first ring flow 13 gradually flows towards the second water guide platform 24 to clean the first wall surface 25 between the first water guide platform 22 and the second water guide platform 24, then the second ring flow 14 is formed on the second water guide platform 24, the second ring flow 14 gradually flows towards the water seal surface 15 to clean the second wall surface 26 between the second water guide platform 24 and the water seal surface 15, and then the water seal surface 15 is injected.

[0050] The washing method of the present application, the area between the first water guide platform 22 and the water seal surface 15, i.e. the first wall surface 25 and the second wall surface 26, is the area with the thinnest water film. Due to the existence of the second water guide platform 24, the second ring flow 14 is formed, and a lot of water is gathered in the originally water-lacking annular area. The water flow from the first water guide platform 22 on both sides of the pot surface 11 is relatively large, but the water flow will not directly flow into the water seal surface 15, but will flow along the second water guide platform 24 to the front and rear of the pot surface 11 where the water flow is small. That is, the water flow in the first ring flow 13 on one side of the pot surface 11 flows into the second water guide platform 24 and then flows along the pot surface 11 towards the front of the pot surface 11, and the water flow in the first ring flow 13 on the other side of the pot surface 11 flows into the second water guide platform 24 and then flows along the pot surface 11 towards the rear of the pot surface 11. Due to the accumulation and flow of the water flow in the second water guide platform 24, the distribution of the washing water flow of the pot surface 11 becomes more uniform, and the washing effect is better. See Figure 11 .

[0051] The above is only a specific embodiment of the present application, but the design concept of the present application is not limited thereto, and any non-essential modification of the present application using the concept shall be deemed as an infringement of the protection scope of the present application.
