Description

Technical Field

[0001] The present invention relates to the technical field of sanitary ware, and particularly to a swirl flushing toilet bowl. Background Art

[0002] In the prior art, a flush-down toilet bowl generally adopts a counter-flush surrounding flushing structure or a swirl flushing structure.

[0003] For the counter-flush surrounding flushing structure, the flushing holes are arranged at the rear end inside the seat ring and are symmetrically distributed. The flushing holes include main flushing holes arranged on both sides and a plurality of secondary flushing holes arranged in the middle. The openings of the main flushing holes face forward. During flushing, the two main flushes rush out from both sides and converge at the middle of the front end of the bladder, flow into the wash surface from the front end of the bladder, and together with the water rushed out from the rear secondary flushing holes, press the dirt in the wash surface into the sewage pipe. In the process of this flushing structure, the two main flushes are likely to collide at the front end during flushing, causing splashing, and the flushing effect is not ideal, and it is difficult to press the dirt (especially the dirt floating on the water seal surface) into the sewage pipe.

[0004] For the swirl flushing structure, the flushing holes are arranged at the rear end inside the seat ring, and the flushing holes are arranged along the tangential direction of the bladder. The water flows out through the flushing holes and directly flows from the bladder to the wash surface, forming a swirling water flow. However, in this flushing structure, the water pressure is high at the flushing holes, and some of the water is likely to collide with the inner wall of the wash surface after flowing out through the flushing holes, easily causing splashing. Secondly, the water flow rushed out through the flushing holes moves downward under the influence of gravity during the swirl flushing process, and the upper edge of the wash surface and the downstream side of the flushing are difficult to clean thoroughly, resulting in a washing blind area. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide a swirl flushing toilet bowl in view of the existing technical status. The toilet bowl in the embodiments of the present invention has a good anti-splashing effect, can comprehensively and fully clean the entire wash surface, solves the problem of washing blind areas existing in the prior art, and has a good flushing and sewage discharge effect.

[0006] To achieve the above purpose, the embodiments of the present invention adopt the following technical solutions:

[0007] The embodiments of the present invention provide a swirl flushing toilet bowl, including a seat ring and a wash surface. The seat ring is provided with an inner edge wall surrounding the wash surface. The rear end of the inner edge wall is provided with a flushing port for forming annular water supply in the wash surface. The flushing port includes main flushing holes and secondary flushing holes with openings arranged along the same rotation direction.

[0008] A water guide channel is arranged between the inner edge wall and the wash surface. The water guide channel is arranged at the upper end of the wash surface and surrounds the wash surface. And the water guide channel is inclined downward from outside to inside.

[0009] The water guide channel is provided with a first water guide section and a second water guide section. The first water guide section is provided with an upstream section communicating with the main flushing hole and a downstream section located inside the secondary flushing hole.

[0010] The slope of the first water guide section increases in the flowing direction from the upstream section to the downstream section, and the slope of the second water guide section increases in the flowing direction from the upstream end to the downstream end.

[0011] In some embodiments, the width of the first water guide section decreases in the flowing direction from the upstream section to the downstream section, and the width of the second water guide section decreases in the flowing direction from the upstream end to the downstream end.

[0012] In some embodiments, an inwardly arched arc-shaped guide slope is provided between the water guide channel and the cleaning surface.

[0014] In some embodiments, on the same horizontal plane, the curvature of the front end of the cleaning surface > the curvature of both sides of the cleaning surface > the curvature of the rear end of the cleaning surface.

[0015] In some embodiments, the opening of the main flushing hole faces the front end of the cleaning surface, the opening of the secondary flushing hole faces the rear end of the cleaning surface downward, and the flow rate of the main flushing hole is greater than that of the secondary flushing hole. An annular guide slope and a sewage outlet are respectively provided at the upper and lower ends of the cleaning surface. The upper end of the annular guide slope is connected to the water guide channel, and the annular guide slope is inclined downward from top to bottom towards the direction close to the sewage outlet. The flow rate of the main flushing hole is set to a flow rate value that can supply water to swirl around the annular guide slope one and a half weeks, and the flow rate of the secondary flushing hole is set to a flow rate value that can supply water to swirl around the annular guide slope half a week.

[0016] In some embodiments, the flow rate of the main flushing hole is 60% - 75% of the total flow rate, and the flow rate of the secondary flushing hole is 25% - 40% of the total flow rate.

[0017] In some embodiments, a circular steep slope for forming a drop is connected to the lower end of the annular guide slope. The circular steep slope is inclined backward from top to bottom, and the depth of the cleaning surface increases from the front end towards the direction close to the sewage outlet.

[0018] In some embodiments, the included angle between the circular steep slope and the Y direction is 10° - 20°, and the included angle between the annular guide slope and the Y direction is 75° - 80°.

[0019] In some embodiments, a sewage discharge pipe is further included. The sewage discharge pipe is provided with a descending section and an ascending section that are interconnected.

Even in the case of low flushing water volume, the entire cleaning surface can be washed clean and the dirt can be smoothly discharged from the sewage discharge pipe. The flushing and sewage discharge effects are good, and at the same time, the problem of water splashing during the flushing process is effectively prevented, and the anti-splash effect is good.

[0036] The present invention will be further described below in conjunction with the drawings and embodiments:

[0037] Embodiment 1

[0038] Please refer to Figures 1 to 4 as shown. This embodiment discloses a rotary flushing toilet, which includes a seat ring 1 and a cleaning surface 2. The seat ring 1 is provided with an inner edge wall 11 surrounding the cleaning surface 2. The rear end of the inner edge wall 11 is provided with a flushing water port 3 for forming annular water supply in the cleaning surface 2. The flushing water port 3 includes a main flushing hole 31 and a secondary flushing hole 32 with openings arranged along the same rotation direction. In this embodiment, the openings of the main flushing hole 31 and the secondary flushing hole 32 are arranged in the counterclockwise direction. The main flushing hole 31 and the secondary flushing hole 32 are respectively located on the left and right sides of the rear end of the inner edge wall 11. The main flushing hole 31 is communicated with the water inlet channel through the main flushing water path, and the secondary flushing hole 32 is communicated with the water inlet channel through the secondary flushing water path. The rear end of the water inlet channel is provided with a water inlet.

[0039] A water guide channel 4 is provided between the inner edge wall 11 and the cleaning surface 2. The water guide channel 4 is arranged at the upper end of the cleaning surface 2 and surrounds the cleaning surface 2. And the water guide channel 4 is inclined downward from the outside to the inside.

[0040] The water guide channel 4 is provided with a first water guide section 41 and a second water guide section 42. The first water guide section 41 is provided with an upstream section 411 communicating with the main flushing hole 31 and a downstream section 412 located inside the secondary flushing hole 32. The second water guide section 42 is provided with an upstream end 421 communicating with the secondary flushing hole 32 and a downstream end 422 located inside the main flushing hole 31. Among them, the downstream end 422 of the second water guide section 42 is communicated with the upstream section 411 of the first water guide section 41.

[0041] The slope of the first water guiding section 41 increases gradually from the upstream section 411 to the downstream section 412 in the flow direction, and the slope of the second water guiding section 42 increases gradually from the upstream end 421 to the downstream end 422 in the flow direction.

[0042] In this embodiment, water flows into the seat ring 1 through the water inlet, and then flows to the main flushing hole 31 and the auxiliary flushing hole 32. Splashing caused by excessive local water pressure is avoided by diversion, and the main flushing hole 31 and the auxiliary flushing hole 32 are arranged along the same rotation direction, and a water guide 4 is arranged between the inner edge wall 11 and the clean washing surface 2. The main flushing water flow flushed out through the main flushing hole 31 flows outward along the first water guide section 41, flows from the upstream section 411 to the front end, and swirls to the downstream section 412. The auxiliary flushing water flow flushed out through the auxiliary flushing hole 32 flows outward along the second water guide section 42, flows from the upstream end 421 to the downstream end 422. The two water flows rotate along the same rotation direction to form a vortex flow together, and generate a 360-degree rotation on the clean washing surface 2 under the guidance of the water guide 4. Since the first water guide section 41 is connected to the main flushing hole 31, and the second water guide section 42 is connected to the auxiliary flushing hole 32, the water flows out of the flushing hole 3 After that, it will flow along the water guide channel 4 to prevent the water from splashing out after rushing out of the flushing port 3. Because the water guide channel 4 is circumferentially arranged around the upper end of the cleaning surface 2, and the water guide channel 4 is inclined downward from the outside to the inside, the water has a tendency to flow toward the cleaning surface 2 on the water guide channel 4, further suppressing splashing. At the same time, due to the existence of the water guide channel 4, the water can flow around for a longer distance at the height of the water guide channel 4. After rushing out of the flushing port 3, part of the water flows along the water guide channel 4, and part of it flows toward the cleaning surface 2 following the inclined trend of the water guide channel 4. The upper end of the waterway trajectory of the vortex flow formed by the water flow can cover the upper end of the cleaning surface 2. The vortex flow brings a strong impulse force, which can more effectively flush the entire cleaning surface 2 and flush the dirt into the sewage pipe 7, and can rotate to break up the dirt on the tip of the bile. Even in the case of low flushing water volume, the entire cleaning surface 2 can be cleaned and the dirt can be smoothly discharged from the sewage pipe 7, and the flushing and sewage discharge effect is good. Figures 6 to 11 As shown, the slope of the first water guide section 41 increases from the upstream section 411 to the downstream section 412 in the flow direction, and the slope of the second water guide section 42 increases from the upstream end 421 to the downstream end 422 in the flow direction, which is conducive to the water flow entering the water channel 4 from the flushing port 3 in an orderly manner and entering the washing surface 2 from the water channel 4 in an orderly manner without turbulence, which is conducive to the formation of a vortex flow while effectively suppressing splashing water.

[0043] Therefore, this embodiment, through the mutual cooperation between the flushing port 3 composed of the main flushing hole 31 and the auxiliary flushing hole 32 and the obliquely arranged water conduit 4, combined with the slope design of the water conduit 4, can make the water flow form a vortex flow with a water path trajectory to cover the entire cleaning surface 2. Even in the case of low flushing water volume, the entire cleaning surface 2 can be cleaned and the dirt can be smoothly discharged from the drain pipe 7, with good flushing and sewage discharge effects. At the same time, it can effectively prevent the problem of splashing water during the flushing process, and has a good anti-splashing effect.

[0044] In addition, since the flushing water inlet 3 is connected to the water guiding channel 4 without any blocking setting, after the flushing is completed, there is no water accumulation remaining in both the main flushing water path and the secondary flushing water path, so as to inhibit the frequent generation of water stains, which is beneficial to household sanitation cleaning.

[0045] See Figure 1 , Figure 2 and Figure 4 As shown in, the width of the first water guiding section 41 decreases in the flowing direction from the upstream section 411 towards the downstream section 412, and the width of the second water guiding section 42 decreases in the flowing direction from the upstream end 421 towards the downstream end 422.

[0046] When the water flow just rushes out from the main flushing holes 31 and the secondary flushing holes 32, the water volume is the largest. The widths of the upstream section 411 on the first water guiding section 41 and the upstream end 421 on the second water guiding section 42 are set to be wider, so that the water flow can enter the water guiding channel 4 more orderly and smoothly. The widths of the first water guiding section 41 and the second water guiding section 42 decrease respectively along the water flow direction, which is beneficial for the main flushing water and the secondary flushing water not to be disordered when moving forward on the water guiding channel 4, and at the same time enables the water flow to enter the washbasin 2 orderly from the water guiding channel 4, effectively inhibiting splashing water while facilitating the formation of a vortex flow.

[0047] See Figure 2 and Figure 10 As shown in, an arc-shaped guiding slope 5 that arches inwards is provided between the water guiding channel 4 and the washbasin 2. The arc-shaped guiding slope 5 is beneficial for the water flow to flow towards the washbasin 2 along the arc-shaped guiding slope 5 when flowing on the water guiding channel 4, further effectively inhibiting splashing water.

[0048] The water guiding channel 4 is inclined upwards from front to back. After the flushing is completed, the remaining water droplets in the main flushing water path and the secondary flushing water path can be drained more quickly.

[0049] On the same horizontal plane, the curvature of the front end of the washbasin 2 > the curvature of both sides of the washbasin 2 > the curvature of the rear end of the washbasin 2, so as to facilitate the main flushing water flow to flow along the water guiding channel 4 towards the front end and swirl to the downstream section 412.

[0050] See Figure 5 , Figure 10 and Figure 11 As shown in, the opening of the main flushing hole 31 faces the front end of the washbasin 2, the opening of the secondary flushing hole 32 faces the rear end of the washbasin 2 downwards, and the flow rate of the main flushing hole 31 is greater than that of the secondary flushing hole 32. An annular guiding slope 21 and a sewage outlet 6 are respectively provided at the upper and lower ends of the washbasin 2. The upper end of the annular guiding slope 21 is connected to the water guiding channel 4, and the annular guiding slope 21 is inclined downwards towards the direction close to the sewage outlet 6 from top to bottom. The flow rate of the main flushing hole 31 is set to a flow rate value that can supply the water flow to swirl around the annular guiding slope 21 for one and a half weeks, and the flow rate of the secondary flushing hole 32 is set to a flow rate value that can supply the water flow to swirl around the annular guiding slope 21 for half a week.

[0051] In this embodiment, the flow rate of the main flushing hole 31 is greater than that of the secondary flushing hole 32, which is conducive to forming main and secondary flushing water flows with different potential energies. The velocity of the main flushing water flow is greater, and it can flow from the rear end on the left side to the front end along the water guide channel 4 and swirl to the rear end on the right side. The velocity of the secondary flushing water flow is smaller, and it can swirl from the rear end on the right side to the left side along the water guide channel 4. The two water flows complement each other to form a 360-degree water curtain to wash the entire cleaning surface 2. Even when the water volume is small, the swirling water can generate a 360-degree swirling flushing water flow without a washing blind area.

[0052] In addition, by controlling the flow rates of the main flushing hole 31 and the secondary flushing hole 32, the flow rate of the main flushing hole 31 is set to a flow rate value that allows the water flow to swirl around the annular guiding slope 21 for one and a half weeks, and the flow rate of the secondary flushing hole 32 is set to a flow rate value that allows the water flow to swirl around the annular guiding slope 21 for half a week. Thus, after the two water flows fully scour the annular guiding slope 21, they converge at the front end, form a rotating water flow again, enter the lower end of the annular guiding slope 21, and scour the bottom of the cleaning surface 2. Since the dirt dropping point is located at the front end position of the sewage discharge port 6, the water volume converges at the front end and then drops, which is more conducive to flushing the dirt to the sewage discharge port 6, further improving the flushing and sewage discharge capacity.

[0053] The flow rate of the main flushing hole 31 is 60% - 75% of the total flow rate, and the flow rate of the secondary flushing hole 32 is 25% - 40% of the total flow rate. More preferably, the flow rate of the main flushing hole 31 is 70% of the total flow rate, and the flow rate of the secondary flushing hole 32 is 30% of the total flow rate. Within this flow rate range, even when the water volume is small, the main and secondary flushing water flows can form a 360-degree water curtain to wash the entire cleaning surface 2, and at the same time, it can achieve the purpose of the main flushing water flow swirling around the annular guiding slope 21 for one and a half weeks and the secondary flushing water flow swirling around the annular guiding slope 21 for half a week.

[0054] Embodiment 2

[0055] See Figures 12 to 13 As shown, the difference between this embodiment and Embodiment 1 is that a circular steep slope 22 for forming a drop is connected to the lower end of the annular guiding slope 21. The circular steep slope 22 slopes backward from top to bottom, and the depth of the cleaning surface 2 increases from the front end toward the direction close to the sewage discharge port 6.

[0056] On the one hand, by arranging the annular guiding slope 21 and the circular steep slope 22 in a top-down manner, a circular stepped structure with a large drop is formed at the bottom of the cleaning surface 2. When flushing, when the water flow flows from the annular guiding slope 21 to the circular steep slope 22, the inner wall of the bile tip becomes extremely steep, and the depth of the cleaning surface 2 increases from the front end toward the direction close to the sewage discharge port 6, forming a certain height drop. The angle drop and height drop are used to make the water flow generate gravitational potential energy, so that the generated gravitational potential energy can be used to increase the water flow impact force and accelerate the speed of the water flow entering the sewage pipe 7, effectively improving the sewage discharge capacity to ensure good sewage discharge capacity even at low water volumes.

[0057] In addition, the central axis of the vortex flow formed in the prior art is usually arranged in the vertical direction, and the bottom is located at the front end of the sewage outlet 6. In this embodiment, when the water flow swirls and flushes from the annular guiding slope 21 into the bottom of the cleaning surface 2, due to the annular step structure at the bottom of the cleaning surface 2, the swirling water flow can form an oblique vortex flow at the bottom of the cleaning surface 2, and the bottom of the vortex flow points to the sewage outlet 6. The pulling force generated at the bottom of the vortex flow can quickly pull the dirt at the bottom of the cleaning surface 2 into the sewage pipe 7, and even when the water volume is low, it is easier to pull the dirt floating on the water seal into the sewage pipe 7, further improving the flushing and sewage discharge effect.

[0058] See Figure 12 As shown, the included angle between the annular steep slope 22 and the Y direction is 10° - 20°, and the included angle c between the annular guiding slope 21 and the Y direction is 75° - 80°.

[0059] Preferably, the included angle a between the front end of the annular steep slope 22 and the Y direction is less than the included angle b between the rear end of the annular steep slope 22 and the Y direction, which is more conducive to the formation of an oblique vortex flow.

[0060] Preferably, the height of the annular steep slope 22 is greater than 45 mm to facilitate forming a sufficient height difference.

[0061] By controlling the included angle between the annular steep slope 22 and the Y direction and the included angle c between the annular guiding slope 21 and the Y direction, an annular step structure can be formed between the annular steep slope 22 and the annular guiding slope 21.

[0062] See Figure 12 As shown, it further includes a sewage pipe 7. The sewage pipe 7 is provided with a descending section 71 and an ascending section 72 that are interconnected. One end of the descending section 71 away from the ascending section 72 is connected to the sewage outlet 6, and the descending section 71 is located below the sewage outlet 6 and the cleaning surface 2. The lower end of the inner wall of the ascending section 72 extends upward to form an arc-shaped rib 73 for raising the water seal liquid level. The arc-shaped rib 73 is located at one end of the ascending section 72 away from the descending section 71, and the cross-section of the arc-shaped rib 73 is crescent-shaped.

[0063] In this embodiment, the descending section 71 is located below the sewage outlet 6 and the cleaning surface 2, which can make the bottom of the formed vortex flow extend into the sewage pipe 7, and is more conducive to pulling the dirt at the bottom of the cleaning surface 2 into the sewage pipe 7 through the pulling force generated at the bottom of the vortex flow, further enhancing the flushing and sewage discharge performance. At the same time, by setting the arc-shaped rib 73, while ensuring that the water seal has a sufficient depth, the overall height of the sewage pipe 7 can be effectively reduced. When the toilet is a wall-hung toilet, under the same installation height condition, more space can be reserved at the bottom of the toilet after installation, which is conducive to the sanitation cleaning of the ground under the toilet.

[0064] The above are only the preferred embodiments of the present invention, and there is no restriction on the present invention in any form. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content prompted above within the scope of the technical solution of the present invention. However, as long as the content does not depart from the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention.
