Description

Technical Field

[0001] The present invention relates to the technical field of bathroom equipment, in particular to a toilet. Background Art

[0002] Most existing toilets input water flow at one side of the toilet bowl, so that the water flow forms a flushing vortex in the toilet bowl to clean the toilet bowl after use, thereby ensuring the cleanliness of the toilet bowl.

[0003] However, as the flushing vortex swirls within the toilet bowl, the impact of the water flow gradually decreases as the vortex flows in its direction. Furthermore, as the water swirls within the toilet bowl, it is subjected to centrifugal force at bends, causing the water to flow along the bowl under the centrifugal force. This results in less water flowing into the bowl's inner wall at bends, resulting in poor cleaning of the bowl's inner wall below the water outlet. This also results in uneven cleaning of the bowl's inner wall, which can easily lead to incomplete cleaning. Furthermore, under low water pressure conditions, the flushing vortex cannot be effectively formed to fully flush the bowl, making toilets require higher flushing water pressures and less practical. Summary of the Invention

[0004] The main object of the present invention is to provide a toilet bowl, which aims to make the toilet bowl flush more even and achieve better cleaning effect even at low water pressure.

[0005] To achieve the above objectives, the present invention provides a toilet comprising a toilet bowl and a flushing structure. The flushing structure is connected to the top of the toilet bowl and disposed around the toilet bowl. The flushing structure defines a water flow channel that surrounds and connects to the toilet bowl. At least one side of the flushing structure is provided with a water outlet that connects to the water flow channel. The flushing structure defines a guide surface that connects to the inner wall of the toilet bowl, the guide surface being arranged at an angle to the horizontal plane. The water flow channel defines at least one bend. The guide surface is provided with an oblique flow portion at the bend, which bends and connects to the inner wall of the toilet bowl.

[0006] Optionally, the angle between the guide surface and the horizontal plane is defined as α, and the condition is satisfied: 7°≤α≤15°.

[0007] Optionally, the angle between the guide surface and the inner wall of the pot is defined as β, and the condition is satisfied: 130°≤β≤155°.

[0008] Optionally, the guide surface includes a horizontal flow section and a diversion section, the horizontal flow section is arranged around the pot, and the horizontal flow section is arranged at an angle to the horizontal plane; the diversion section is connected to the horizontal flow section and is bent to connect to the pot, the width of the diversion section extending from the water outlet to the curve structure is gradually increased, and the part of the diversion section at the curve structure forms the oblique flow portion.

[0009] Optionally, the diversion section is in an arc shape, and the arc angle of the diversion section is defined as γ, which satisfies the following condition: 8°≤γ≤35°.

[0010] Optionally, the width of the horizontal flow section is defined as W, and the condition is satisfied: 15 mm ≤ W ≤ 35 mm.

[0011] Optionally, the flushing structure includes a guide platform and a water retaining ring, the guide platform is connected to the top of the toilet pot, and the surface of the guide platform is formed as the guide surface; the water retaining ring is bent and connected to the outer peripheral side of the guide platform and is arranged around the guide platform, and the water retaining ring and the guide platform enclose the water flow channel.

[0012] Optionally, the angle between the surface of the water retaining ring facing the guide platform and the horizontal plane is defined as δ, and the condition is satisfied: 94°≤δ≤110°.

[0013] Optionally, the circumference of the inner circumference of the water retaining ring is defined as L, and the condition is satisfied: 1000 mm ≤ L ≤ 1200 mm.

[0014] Optionally, at least one water outlet is protruding from the inner circumference of the water retaining ring, the outlet being located on the surface of the guide platform and having the water outlet formed therein. Also, the toilet bowl and the flushing structure are both made of ceramic. Also, the top of the toilet bowl has an elliptical cross-section.

[0015] The technical solution of the present invention forms a water flow channel above the toilet bowl by utilizing a flushing structure. Water can flow well around the toilet bowl in the water flow channel. The guide surface of the flushing structure connecting to the inner wall of the toilet bowl is arranged at an angle with the horizontal plane, so that the water has a certain downward trend when flowing on the guide surface. As the water flows around the toilet bowl on the guide surface, it is continuously diverted into the toilet bowl by gravity. As a result, the water can be transported into the toilet bowl from any point above the toilet bowl, which is conducive to more uniform flushing of the toilet bowl by the water flow. At the same time, in the bend structure of the water flow channel, the water flow is easily affected by the centrifugal force when it turns and flows along the water flow channel, which makes the water flow into the toilet bowl from the bend structure less. At this time, by setting an oblique flow portion on the guide surface of the bend structure, the drainage effect of the oblique flow portion can make the part of the water flow away from the bend structure have a greater downward trend when the water flows in the bend structure, so that the water flow can be well diverted into the toilet bowl when it flows in the bend structure, making the water flow in various places in the toilet bowl more uniform, thereby improving the cleaning effect of the toilet bowl.

[0016] Among them, the flushing structure is used to guide the water flow, so that the water flows around the toilet bowl in the water flow channel and is continuously diverted into the toilet bowl. Even if water with lower water pressure is used, it can flow around the toilet bowl well under the guidance of the flushing structure, achieving uniform flushing of the water flow, effectively reducing the water pressure requirement of the toilet for flushing water, and further improving the practicality and reliability of the toilet.

[0031] Most existing toilets use water flow fed into the side of the bowl, creating a flushing vortex within the bowl to clean the bowl after use and ensure a clean, tidy bowl. However, as the flushing vortex rotates within the bowl, the impact of the water gradually decreases with the direction of the vortex's flow. Furthermore, as the water swirls within the bowl, it is subject to centrifugal force at bends, causing the water to flow against the bowl under the centrifugal force. This results in less water flowing into the bowl's inner wall at bends, resulting in poor cleaning of the bowl's inner wall below the water outlet. This also causes uneven cleaning of the bowl's inner wall, which can easily lead to incomplete cleaning. Furthermore, under low water pressure conditions, the flushing vortex cannot be effectively formed to fully flush the bowl, making toilets require high flushing water pressure and poor practicality. To address these issues, the present invention proposes a toilet 1000.

[0032] Reference Figures 1 to 6 In this embodiment of the present invention, the toilet 1000 includes a toilet bowl 300 and a flushing structure 100. The flushing structure 100 is connected to the top of the toilet bowl 300 and is disposed around the toilet bowl 300. The flushing structure 100 defines a water flow channel 13 that surrounds and connects to the toilet bowl 300. A water outlet 311 is defined on at least one side of the flushing structure 100, connecting to the water flow channel 13. The flushing structure 100 defines a guide surface 11 that connects to the inner wall of the toilet bowl 300. The guide surface 11 is arranged at an angle to the horizontal plane. The water flow channel 13 has at least one curved structure 131. The guide surface 11 has an oblique flow portion 1131 at the curved structure 131, which bends to connect to the inner wall of the toilet bowl 300.

[0033] The technical solution of the present invention utilizes the flushing structure 100 to form a water flow channel 13 above the commode 300. This allows water to flow smoothly around the commode 300 within the water flow channel 13. Furthermore, the guide surface 11 of the flushing structure 100, which connects to the inner wall of the commode 300, is arranged at an angle to the horizontal plane. This allows water to have a certain downward slope when flowing along the guide surface 11. As the water flows around the commode 300 on the guide surface 11, it is continuously diverted into the commode 300 by gravity. Consequently, water can be transported from any point above the commode 300 into the commode 300, facilitating a more uniform flushing of the commode 300. At the same time, at the bend structure 131 of the water flow channel 13, the water tends to flow along the water flow channel 13 due to the centrifugal force when turning, resulting in a smaller amount of water flowing into the toilet bowl 300 from the bend structure 131. In this case, by providing the oblique flow portion 1131 on the guide surface 11 at the bend structure 131, the diversion effect of the oblique flow portion 1131 can cause the portion of water flowing away from the bend structure 131 to have a greater downward trend when the water flows through the bend structure 131. This allows the water to be effectively diverted into the toilet bowl 300 while flowing through the bend structure 131, resulting in a more uniform water flow throughout the toilet bowl 300 and improved cleaning performance of the toilet bowl 1000.

[0034] The flushing structure 100 guides the water flow so that it flows around the commode 300 within the water flow channel 13 and is continuously diverted into the commode 300. Even water at a relatively low pressure can flow well around the commode 300 under the guidance of the flushing structure 100, achieving uniform flushing. This effectively reduces the flushing water pressure requirement of the toilet 1000 and further improves the practicality and reliability of the toilet 1000.

[0035] Secondly, the water flow channel 13 is formed with at least one curved structure 131. This can be formed at both the front and rear ends of the water flow channel 13, with the oblique flow portions 1131 provided at both ends. Alternatively, a curved structure 131 can be formed at one end of the water flow channel 13, with the oblique flow portion 1131 provided at one end. Furthermore, in the present application, each curved structure 131 formed in the water flow channel 13 can be provided with the oblique flow portion 1131. Alternatively, the water flow channel 13 can be formed with multiple curved structures 131, with the oblique flow portion 1131 provided on one or more of the curved structures 131.

[0036] Further, refer to Figure 4 and Figure 5 In one embodiment of the present invention, the angle between the guide surface 11 and the horizontal plane is defined as α, which satisfies the following conditions: 7°≤α≤15°.

[0037] In this embodiment, the guide surface 11 is arranged at an angle to the horizontal plane, so that the guide surface 11 is arranged at a certain inclination. As a result, the water flowing on the guide surface 11 can have a certain downward trend toward the toilet bowl 300 under the action of gravity. In addition, the water flowing on the guide surface 11 can be continuously diverted into the toilet bowl 300 for cleaning, thereby improving the cleaning effect of the toilet 1000. The angle α between the guide surface 11 and the horizontal plane can be set between 7° and 15°. When α is ≥ 7°, as the angle increases, the downward slope of the water flowing on the guide surface 11 becomes greater, thereby enabling the water flowing on the guide surface 11 to be better diverted into the toilet bowl 300 for cleaning, further achieving a better cleaning effect. When α is ≤ 15°, within this angle range, the inclination angle of the guide surface 11 is not too large, resulting in the water being completely diverted into the toilet bowl 300 before it reaches the end of the water flow channel 13. This allows the water to flow better on the guide surface 11 around the toilet bowl 300, resulting in a more uniform and better flushing effect of the toilet 1000.

[0038] Reference Figure 4 and Figure 5 In one embodiment of the present invention, the angle between the guide surface 11 and the inner wall of the pot 300 is defined as β, which satisfies the following condition: 130°≤β≤155°.

[0039] In this embodiment, the angle formed between the guide surface 11 and the inner wall of the toilet pot 300 allows the water to flow more smoothly along the inner wall of the toilet pot 300 when it is diverted from the guide surface 11 into the toilet pot 300, thereby increasing the flushing force of the water on the inner wall of the toilet pot 300. The angle β between the guide surface 11 and the inner wall of the commode 300 can be set between 130° and 155°. When β is ≥ 130°, as the angle increases, the water diverted from the guide surface 11 to the commode 300 can flow more effectively along the inner wall of the commode 300. This allows the water to better flush the inner wall of the commode 300 under the effects of gravity and the diversion of the commode 300, further improving the flushing effect of the toilet 1000. When β is ≤ 155°, this angle range helps prevent the angle between the commode 300 and the guide surface 11 from being too large, allowing the pot body of the commode 300 to be more concave, thereby increasing the storage space of the commode 300 and improving the user experience. Furthermore, within this angle range, the force of gravity acting on the water is greater, further improving the flushing force of the water and achieving a better flushing effect.

[0040] Further, refer to Figure 2 、 Figure 3 and Figure 4In one embodiment of the present invention, the guide surface 11 includes a flat flow section 111 and a diverter section 113. The flat flow section 111 is disposed around the pot 300 and is arranged at an angle to the horizontal plane. The diverter section 113 is connected to the flat flow section 111 and is bent to connect to the pot 300. The width of the diverter section 113 gradually increases from the water outlet 311 to the curved structure 131. The portion of the diverter section 113 at the curved structure 131 forms an oblique flow portion 1131.

[0041] In this embodiment, by providing a diverter section 113 between the horizontal flow section 111 and the toilet bowl 300, the diverter section 113 can further guide the water flow as it flows along the horizontal flow section 111, allowing the water flow to flow through the diverter section 113 and into the toilet bowl 300 for flushing, further enhancing the flushing effect of the water flow. The diverter section 113 can be a curved structure with a certain width. This allows the water flow to flow along the horizontal flow section 111 and be diverted to the diverter section 113 by gravity. The curved structure of the diverter section 113 can improve the fluidity of the water flow along the diverter section 113, thereby allowing the water flow to obtain greater gravitational potential energy, thereby achieving a better flushing effect. As the flushing water flows from the outlet 311 to the curved structure 131, it is gradually affected by the centrifugal force of the flushing structure 100 and adheres to the inner wall of the water channel 13. By gradually increasing the width of the diverter section 113, the portion of the water that departs from the inner wall of the water channel 13 as it flows from the outlet 311 to the curved structure 131 is more easily diverted into the toilet bowl 300 by the wider diverter section 113. This results in a more uniform flushing water flow within the toilet bowl 300, achieving a more uniform and reliable cleaning effect, further enhancing the practicality and reliability of the toilet 1000. Furthermore, as the water flows from the outlet 311 to the curved structure 131, the width of the flat flow section 111 can be reduced, further improving the diversion of the water within this area into the toilet bowl 300 and achieving a better flushing effect.

[0042] Further, refer to Figure 4 and Figure 6 In one embodiment of the present invention, the diversion section 113 is in an arc shape, and the arc angle of the diversion section 113 is defined as γ, which satisfies the following condition: 8°≤γ≤35°.

[0043] In this embodiment, by making the diverter section 113 into an arc shape, a certain chamfer structure can be formed in the diverter section 113, which is conducive to making the transition between the flushing structure 100 and the toilet bowl 300 smoother, and improving the fluidity of water when flowing through the diverter section 113 into the toilet bowl 300, so that the water can better enter the toilet bowl 300 and clean the inner wall of the toilet bowl 300. The arc angle γ of the diverter section 113 can be set between 8° and 35°. When γ is ≥ 8°, the smoothness of the diverter section 113 increases as the angle increases, thereby improving the fluidity of water flowing through the diverter section 113, thereby increasing the efficiency of water entering the toilet 300 and the flow rate of the water. When γ is ≤ 35°, within this angle range, the arc angle of the diverter section 113 is not too large, which facilitates better diversion of the water to the inner wall of the toilet 300 through the diverter section 113, thereby effectively flushing the inner wall of the toilet 300 and reducing the amount of water flowing directly into the sewage outlet in the center of the toilet 300, further improving the practicality and stability of the toilet 1000.

[0044] Further, refer to Figure 4 and Figure 6 In one embodiment of the present invention, the width of the horizontal flow section 111 is defined as W, which satisfies the following condition: 15 mm ≤ W ≤ 35 mm.

[0045] In this embodiment, the width of the flattening section 111 can be set between 15 mm and 35 mm to better suit the flow of water. When W ≥ 15 mm, the area of ​​the flattening section 111 increases as the width increases, allowing the water to better flow around the commode 300 under the backflow effect of the flattening section 111, achieving a more uniform flushing effect. When W ≤ 35 mm, the area of ​​the flattening section 111 is not too large, allowing the water flowing along the flattening section 111 to be better diverted into the commode 300 to clean the commode 300, further improving the stability and reliability of the toilet 1000 and enhancing the cleaning effect of the toilet 1000.

[0046] Reference Figure 1 、 Figure 2 and Figure 4 In one embodiment of the present invention, the flushing structure 100 includes a guide platform 10 and a water retaining ring 30. The guide platform 10 is connected to the top of the toilet pot 300, and the surface of the guide platform 10 is formed as a guide surface 11; the water retaining ring 30 is bent and connected to the outer peripheral side of the guide platform 10 and is arranged around the guide platform 10. The water retaining ring 30 and the guide platform 10 enclose a water flow channel 13.

[0047] In this embodiment, the inner wall of the water flow channel 13 can be the surface of the guide platform 10 and the inner surface of the water retaining ring 30. When the water flows in the water flow channel 13, it can flow on the surface of the guide platform 10 and the inner surface of the water retaining ring 30, so that the water flow can better flow around the toilet 300. The water retaining ring 30 can be a ring structure with a certain height, so that the water retaining ring 30 can play a certain blocking role when the water flows, and the water flow can be well blocked by the water retaining ring 30 when passing through the bend structure 131 and flow along the inner surface of the water retaining ring 30, so that the water flow can better flow around the water flow channel 13, further improving the flushing uniformity of the toilet 1000 and improving the cleaning effect of the toilet 1000.

[0048] Secondly, by bending the water retaining ring 30 and connecting it to the outer periphery of the guide platform 10, a certain chamfered structure can be formed at the connection between the water retaining ring 30 and the guide platform 10, so that the water flow is smoother when it flows back from the inner surface of the water retaining ring 30 to the surface of the guide platform 10, further improving the fluidity of the water flow, allowing the water flow to flow better, and thereby enhancing the flushing effect of the water flow.

[0049] Further, refer to Figure 4 and Figure 5 In one embodiment of the present invention, the angle between the surface of the water retaining ring 30 facing the guide platform 10 and the horizontal plane is defined as δ, and the condition is satisfied: 94°≤δ≤110°.

[0050] In this embodiment, the angle δ between the surface of the water retaining ring 30 facing the guide platform 10 and the horizontal plane is set between 94° and 110°, so that the water retaining ring 30 has a certain inclination angle, so that when the water flow is affected by the centrifugal force and adheres to the water retaining ring 30, it can have a certain downward trend, so that the water flow can better slide down to the guide platform 10 and be diverted into the toilet bowl 300, further improving the cleaning effect of the toilet 1000. Among them, when δ≥94°, as the angle increases, the inclination angle of the water retaining ring 30 becomes larger, so that the water flowing on the water retaining ring 30 can better slide down to the guide platform 10 and flow, and then can be better diverted into the toilet bowl 300, thereby improving the cleaning effect of the toilet 1000. Moreover, within this angle range, the flushing structure 100 can use a lower water pressure to make the water flow around in the water flow channel 13, further improving the practicality of the toilet 1000. When δ≤110°, the inclination angle of the water retaining ring 30 can be prevented from being too large, so that the water retaining effect of the water retaining ring 30 is better, which is conducive to making the water flow better in the water flow channel 13, further improving the uniform cleaning effect of the toilet 1000.

[0051] Furthermore, in one embodiment of the present invention, the circumference of the inner circumference of the water retaining ring 30 is defined as L, which satisfies the following condition: 1000 mm ≤ L ≤ 1200 mm.

[0052] In this embodiment, by setting the circumference of the inner side of the water retaining ring 30 between 1000 mm and 1200 mm, the overall area of ​​the water flow channel 13 can be made smaller, so that even if a water flow with a lower water pressure is used, the water flow can flow around the water flow channel 13 well, achieving a more uniform flushing effect, and further improving the practicality and reliability of the toilet 1000.

[0053] Further, refer to Figure 1 and Figure 3 In one embodiment of the present invention, at least one water outlet 31 is protruding from the inner circumference of the water retaining ring 30. The water outlet 31 is located on the surface of the guide platform 10 and defines a water outlet 311. Alternatively, the toilet bowl 300 and the flushing structure 100 are both made of ceramic. Alternatively, the top of the toilet bowl 300 has an elliptical cross-section.

[0054] In this embodiment, by providing a water outlet platform 31 on the surface of the guide platform 10, the water outlet platform 31 can be used to better spray water into the water flow channel 13. At the same time, the water outlet platform 31 can form a certain water retaining structure, so that when the water is ejected from the water outlet platform 31 and returns to the water outlet platform 31, it can be better flushed into the toilet pot 300 for cleaning under the blocking effect of the water outlet platform 31, thereby achieving a better cleaning effect.

[0055] Secondly, by using ceramic materials for the commode 300 and the flushing structure 100, the surfaces of the commode 300 and the flushing structure 100 can be made smoother, which helps the water flow better flush dirt on the inner wall of the commode 300, further improving the flushing effect of the toilet 1000. At the same time, the water flow can clean the commode 300 more evenly at any part, making the toilet 1000 more practical and reliable.

[0056] By forming the cross-section of the top of the commode 300 into an elliptical shape, the commode 300 can have a more uniform structure, allowing water to flow better around the commode 300 and making the flow of water diverted into the commode 300 more uniform. This allows the toilet 1000 to achieve a more uniform cleaning effect, further improving the practicality and reliability of the toilet 1000.

[0057] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present description and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
