Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and in particular to a toilet. Background Technology

[0002] The existing wash surface of the flushing toilet adopts a common symmetrical design, with simple curved surfaces at the front and left and right sides, while the back wall of the wash surface is relatively flat. The flushing system adopts a ring-shaped counter-flush design, with multiple water outlets at the center of the rear end. The flushing water flows through the water inlet and rushes out from the rear sides to the front. The inner ring adopts a concave design, with a relatively deep groove between the seat ring and the wash surface. The above design has the following problems: (1) The existing wash surface is prone to dirt residue, and the flushing is not thorough. Moreover, the water flow will generate a lot of noise when impacting the surface. During the flushing process, a large amount of water (5.7L for water efficiency level 2 and above) is required to clean, which is inefficient. (2) All the water outlets are concentrated in the center of the rear end, and the main water outlets are set downwards. Only two smaller water outlets are provided on the sides. This causes most of the water to flow directly into the dirt inlet section, and only a small amount of water flows through the small water outlets on the sides to the washing surface for washing. Although this design helps to accelerate the discharge of dirt, it is easy to cause incomplete coverage of the washing surface and the problem of rinsing dead corners. (3) Multiple water outlets and the concave inner ring are prone to accumulating dirt, making cleaning difficult. Utility Model Content

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. Therefore, the present invention proposes a toilet seat.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A toilet according to an embodiment of the present invention includes a seat ring, an inner ring, a washable surface, and a waste inlet. The inner ring is a continuous annular surface surrounding the washable surface, with its top edge connected to the seat ring and its bottom edge connected to the washable surface. A water outlet is provided on the inner ring, located to the left front of the waste inlet, and the water outlet's flow direction is towards the rear of the inner ring. The washable surface is designed to spiral around the waste inlet, and the washable surface gradually slopes downwards along the spiral direction. The washable surface is divided into an upper washable section. The upper and lower washing surfaces are connected. The starting end of the upper washing surface is connected to the water outlet, and the ending end of the upper washing surface is located to the right rear of the sewage inlet. The ending end of the upper washing surface is connected to the starting end of the lower washing surface, and the ending end of the lower washing surface is connected to the left side of the sewage inlet. The water jet from the water outlet flows through the upper and lower washing surfaces sequentially. The upper washing surface has a convex structure, and the lower washing surface has a concave structure. The radius of curvature of the upper washing surface is smaller than that of the lower washing surface.

[0006] The toilet according to the embodiments of this utility model has at least the following beneficial effects:

[0007] 1. The upper washing surface, with its smaller radius of curvature, provides a strong guiding effect, causing the water flow to deflect rapidly and accumulate kinetic energy. The lower washing surface, with its larger radius of curvature, creates a wide transition surface, providing a buffer for the water flow and preventing violent impacts from sudden changes in direction (the water flow abruptly turning from its initial direction towards the inlet). When the water flows from the upper to the lower washing surface, the gradually changing curvature guides the water flow to spread smoothly along the curved surface, allowing the dispersed jets to gradually merge into a stable surface flow. Simultaneously, the expansion characteristics of the concave structure reduce local flow velocity and minimize eddy formation. Furthermore, it allows the water flow to gradually adjust its pressure distribution during movement, ensuring that the energy of the water flow from the upper washing surface, after being concentrated and guided by the convex surface, is evenly distributed across the entire washing surface through the smooth transition of the concave surface. This avoids potential energy waste and flow turbulence that might occur with the upper washing surface, while ensuring that the water flow from the lower washing surface provides comprehensive rinsing coverage, improving rinsing efficiency.

[0008] 2. The entire washing surface is designed with a spiral inclination from top to bottom around the inlet, creating a certain height difference that provides natural potential energy to the water flow. When the water flows along the inclined surface under gravity, it gains greater acceleration, providing stronger rinsing power without requiring additional water volume, and more effectively removing dirt adhering to the surface. Simultaneously, the inclined design guides the water flow in a directional manner, avoiding the dispersion or stagnation that can occur on a flat surface. This allows the water to flow along a pre-defined path towards the inlet, ensuring no obvious dead zones during rinsing. The directional water flow created by the height difference acts more directly on the dirt, using its own kinetic energy to quickly carry it into the inlet, reducing the need for repeated rinsing with large volumes of water, achieving Class 1 water efficiency. Compared to traditional designs, this reduces rinsing water consumption by approximately 17%. It also promotes an orderly superposition effect between the upper and lower sections of the water flow as it falls. The impact energy of the upper water flow and the continuous propulsive force of the lower water flow work together to generate a continuous and increasing rinsing intensity. This makes it easier for dirt to detach from the cleaning surface and be quickly discharged under the continuous action of the water flow, further improving the overall cleaning effect. In addition, the inclined design allows the water flow to contact the cleaning surface at a smooth angle, rather than impacting vertically, reducing the reaction force when the water flow collides with the surface and lowering the height and probability of splashing. The orderly flow path reduces violent collisions and turbulence between water flows, further suppressing splashing. The gentle transition of the inclined design makes the water flow smoother, avoiding turbulent noise caused by sudden changes in direction or obstruction. At the same time, driven by gravity, the water flow velocity changes more evenly, avoiding sharp noise caused by sudden changes in local flow velocity. This design effectively controls splashing and noise while improving rinsing effect.

[0009] 3. The flushing structure of this utility model adopts a single-outlet vortex flushing design, which makes the water flow form a more concentrated potential energy when flushing, effectively avoiding the problem of insufficient flushing force caused by the dispersed water flow formed by multiple water outlets, ensuring that the water flow can fully cover the toilet from the front to the back, and eliminating the flushing dead corners that may be caused by traditional multiple water outlets.

[0010] According to some embodiments of this utility model, a vertical turning surface is formed between the starting end of the upper washing surface and the ending end of the lower washing surface. The top edge of the turning surface is connected to the upper washing surface, and the bottom edge of the turning surface is connected to the lower washing surface. The turning surface is an arc-shaped curved surface to guide the water flow of the lower washing surface into the inlet.

[0011] According to some embodiments of the present invention, the curvature of the turning surface gradually increases along the direction of water flow.

[0012] According to some embodiments of this utility model, a water channel is provided at the junction of the inner ring surface and the lower washing surface. The starting end of the water channel is located on the right side of the washing surface. The water channel extends from its starting end to the front end of the washing surface and turns along the inner ring surface to the left front of the washing surface. The end of the water channel is located below the water outlet and merges with the turning surface.

[0013] According to some embodiments of the present invention, the outer edge of the water channel is connected to the inner ring surface through a concave arc surface, and the inner edge of the water channel is connected to the lower washing surface through a convex arc surface.

[0014] According to some embodiments of the present invention, the surface of the water channel is a plane inclined in the width direction, and it is inclined downward from the seat surface towards the lower washing surface.

[0015] According to some embodiments of this utility model, the junction between the inner ring surface and the washing surface adopts a concave arc transition.

[0016] According to some embodiments of this utility model, it further includes a water inlet, a water inlet channel, and a vortex flushing channel. The water inlet is connected to the water tank of the toilet. The water inlet channel is connected between the water inlet and the vortex flushing channel. The arrangement path of the vortex flushing channel is from the rear of the washing surface, through the right side of the washing surface, to the left front of the washing surface. The end of the vortex flushing channel is the water outlet.

[0017] According to some embodiments of this utility model, the water outlet is an open type, and its water outlet area is larger than the cross-sectional area of ​​the vortex flushing channel.

[0018] According to some embodiments of this utility model, the water inlet, water inlet channel, vortex flushing channel and water outlet constitute a flushing system, and the flushing system is integrally formed with the ceramic body of the toilet.

[0030] Reference Figure 1-6 A toilet includes a seat surface 100, an inner surface 200, a washable surface, and a waste inlet 400. The inner surface 200 is a continuous annular surface surrounding the washable surface, with its top edge connecting to the seat surface 100 and its bottom edge connecting to the washable surface. The angle between the inner surface 200 and the seat surface 100 is approximately 90°. A water outlet 510 is provided on the inner surface 200, and the water outlet 510 is located to the left front of the waste inlet 400. The water outlet 510 flows towards... On the rear side of the inner ring surface 200, the washing surface is designed to spiral around the inlet 400, and the washing surface gradually slopes downward along the spiral direction. The washing surface is divided into an upper washing surface 310 and a lower washing surface 320. The starting end of the upper washing surface 310 is connected to the outlet 510, and the ending end of the upper washing surface 310 is located to the right rear of the inlet 400. The ending end of the upper washing surface 310 smoothly transitions to the starting end of the lower washing surface 320. Figure 2 The dotted ellipse in the middle marks the transition between the upper washing surface 310 and the lower washing surface 320. The end of the lower washing surface 320 is connected to the left side of the inlet 400. The water jet from the outlet 510 flows through the upper washing surface 310 and the lower washing surface 320 successively. The upper washing surface 310 has a convex structure, while the lower washing surface 320 has a concave structure. The radius of curvature of the upper washing surface 310 is smaller than that of the lower washing surface 320. This design achieves an orderly conversion of the water flow state and efficient energy transfer, enabling the water flow to form a comprehensive rinsing effect, thereby improving rinsing efficiency and reducing water consumption. The unique spiral design effectively reduces the reaction force when the water flow collides with the surface, making the water flow smoother. While enhancing the rinsing effect, it also achieves effective control of splashing and noise.

[0031] In some embodiments of this utility model, reference is made to Figure 1-2A vertical turning surface 321 is formed between the starting end of the upper washing surface 310 and the ending end of the lower washing surface 320. The top edge of the turning surface 321 connects to the upper washing surface 310, and the bottom edge of the turning surface 321 connects to the lower washing surface 320. The turning surface 321 is an arc-shaped curved surface that gradually bends towards the inlet 400 from front to back to guide the water flow from the lower washing surface 320 into the inlet 400. The arc-shaped curved surface design of the turning surface 321 further optimizes the motion of the water flow, allowing the water flow to move along a smooth curved trajectory during the turning process. This effectively reduces the centrifugal force and resistance during the turning process, allowing the water flow to maintain a high speed and kinetic energy when entering the inlet 400, ensuring a continuous flushing effect on the area surrounding the inlet 400.

[0032] In some embodiments of this invention, the curvature of the turning surface 321 gradually increases along the direction of water flow.

[0033] In some embodiments of this utility model, reference is made to Figure 1-4 A water channel 322 is provided at the junction of the inner ring surface 200 and the lower washing surface 320. The starting end of the water channel 322 is located on the right side of the washing surface. The water channel 322 extends from its starting end towards the front end of the washing surface and turns to the left front of the washing surface along the inner ring surface 200. The end of the water channel 322 is located below the water outlet 510 and merges with the turning surface 321. The width of the water channel 322 is relatively narrow, not exceeding 3cm, and is used to guide part of the water flow to the front end of the toilet for flushing, ensuring that the front area is thoroughly cleaned, avoiding the formation of dead corners, and thus further improving the flushing effect.

[0034] In some embodiments of this utility model, reference is made to Figure 3 The outer edge of the water channel 322 is connected to the inner ring surface 200 via a concave arc surface, and the inner edge of the water channel 322 is connected to the lower washing surface 320 via a convex arc surface. The junction of the water channel 322 with the lower washing surface 320 and the inner ring surface 200 adopts a continuous curved surface design without sharp edges, which improves the smoothness of rinsing and reduces the accumulation of dirt.

[0035] In some embodiments of this utility model, reference is made to Figure 3 The surface of the water channel 322 is a plane that slopes in the width direction and slopes downward from the seat surface 100 to the washing surface 320, which can prevent water from accumulating in the water channel 322.

[0036] In some embodiments of this utility model, reference is made to Figure 5The junction between the inner ring surface 200 and the wash surface features a concave arc transition. The continuous curved surface design between the inner ring surface 200 and the wash surface optimizes the irregular structure of traditional toilet inner rings, such as sharp edges and grooves, into a smooth and flowing curved shape. This design effectively reduces friction and resistance between water flow and the inner ring surface 200, allowing water to maintain a stable flow state as it passes through the inner ring surface 200, avoiding eddies or stagnation caused by abrupt structural changes, and improving flushing smoothness. Furthermore, the edgeless design solves the problem of dirt accumulation at traditional sharp edges and grooves, making cleaning easier and effectively reducing the risk of bacterial growth, resulting in more hygienic and safer use. The concave arc transition not only enhances the structural strength of the inner ring surface 200, reduces stress concentration, and extends the toilet's lifespan, but also makes the appearance simpler and smoother, improving the product's aesthetics. In addition, this design facilitates demolding during production, reducing manufacturing difficulty.

[0037] In some embodiments of this utility model, reference is made to Figure 2 , 6 It also includes a water inlet 520, a water inlet channel 530, and a vortex flushing channel 540. The water inlet 520 is connected to the toilet tank, and the water inlet channel 530 connects the water inlet 520 and the vortex flushing channel 540. The vortex flushing channel 540 is arranged from the rear of the wash surface, through the right side of the wash surface, to the front left side of the wash surface. The end of the vortex flushing channel 540 is the water outlet 510. The flushing structure adopts a vortex flushing design. The vortex flushing channel 540 surrounds most of the wash surface, extending from the rear of the toilet to the front, so that the water flow forms a more concentrated potential energy when flushing, effectively avoiding the problem of insufficient flushing force caused by dispersed water flow, and is conducive to forming a high-speed vortex flushing flow. When the water flow rotates counterclockwise along the wash surface, it forms a vortex-like water flow. This not only greatly increases the contact area between the water flow and the inner wall, but also, through continuous rotation, effectively carries dirt to the waste inlet 400, significantly reducing residual stains.

[0038] In some embodiments of this utility model, reference is made to Figure 6 The outlet 510 is an open type, and its outlet area is larger than the cross-sectional area of ​​the vortex channel 540.

[0039] In some embodiments of this utility model, the water inlet 520, water inlet channel 530, vortex flushing channel 540, and water outlet 510 constitute a flushing system, which is integrally formed with the ceramic body of the toilet. The single water outlet 510 has a relatively simple structure and adopts an open design, which can be integrally formed when making the blank, without the need for drilling and additional auxiliary tools as required by the prior art. This reduces the complexity of molds and assembly difficulty in the production process, controls production costs, and facilitates later maintenance and cleaning.

[0040] During use, the flushing water enters through the inlet hole 520, passes through the inlet channel 530 and the vortex flushing channel 540, and exits through the outlet 510. It flows along the upper washing surface 310, with a small amount of water entering the sewage inlet 400 and most of the water flowing to the lower washing surface 320. At the lower washing surface 320, the water flow is split again, with a small amount of water flowing along the water guide channel 322 to the front of the toilet bowl, while most of the water flows through the turning surface 321 into the sewage inlet 400 and is finally discharged from the sewage pipe.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
