Description

Technical Field

[0001] The utility model relates to the technical field of toilets, in particular to a silent energy-gathering flushing toilet. Background Art

[0002] The most common flushing methods for toilets on the market are direct flush and jet siphon. Compared to direct flush toilets, siphon toilets use the siphon principle to draw away waste, and their "S"-shaped pipes have higher water storage, better odor prevention, and are water-saving.

[0003] Since the inner wall of the toilet on the market is wide, when the sewage flushing water flows out from the flush hole on the top of the toilet along the flushing ring to flush the inner wall of the toilet, the water flow rotates from top to bottom along the wide inner wall of the inner wall. The multiple rotations weaken the flushing force. At the same time, the sewage pipe of the siphon toilet is slender and the sewage inlet is small, which makes it easy to get clogged when flushing. Furthermore, in order to improve the sewage discharge effect, such as Figure 1 As shown, a jet channel is added to the bottom of a siphonic toilet. The jet hole of the jet channel is aligned with the sewage inlet of the sewage pipe. When flushing, most of the water is ejected from the jet hole. The powerful impact of the jet flow and the mixture of flushing water and sewage are quickly discharged from top to bottom. Although the jet channel can enhance flushing and sewage removal capabilities, the increased impact of the jet hole causes a certain degree of loudness in the flushing sound, which may cause unnecessary embarrassment to the user.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] The technical scheme of the present application is further illustrated by the specific embodiments. Figures 1 to 6 The technical scheme of the present application is further illustrated by the specific embodiments.

[0040] A mute energy-gathering flushing toilet comprises an inner tank 1, a sewage pipeline 2 and a flushing ring channel 3, the flushing ring channel 3 is arranged at the top of the inner tank 1, and the sewage pipeline 2 is arranged at the bottom of the inner tank 1;

[0041] The flushing ring channel 3 is connected with an external water supply pipeline, the flushing ring channel 3 is provided with a first flushing hole 31 and a second flushing hole 32, the second flushing hole 32 is located at either side of the flushing ring channel 3, and the first flushing hole 31 is located at the rear side of the flushing ring channel 3;

[0042] The front end of the inner tank 1 is provided with a first flushing surface 11 and a second flushing surface 12 connected with each other from top to bottom, the first flushing surface 11 and the second flushing surface 12 have different inclination angles, the water outlet of the first flushing hole 31 is directed to the first flushing surface 11 and forms a first water flow 01, the water outlet of the second flushing hole 32 is directed to the second flushing surface 12 and forms a second water flow 02, and the lower part of the rear end of the inner tank is provided with a water collecting part 13, the water collecting part 13 is located at the upper part of a water seal surface 14, the first water flow 01 and the second water flow 02 are combined into a third water flow 03 at the water collecting part 13, and the third water flow 03 is directed to the sewage pipeline 2.

[0043] By arranging two flushing surfaces (the first flushing surface 11 and the second flushing surface 12) with different inclination angles at the front end of the inner tank 1 and supplying water by the first flushing hole 31 and the second flushing hole 32 to form the first water flow 01 and the second water flow 02, the design can more effectively utilize the water instantaneously ejected from the two flushing holes and flushed through the different flushing surfaces of the inner tank 1, and first achieve the effect of flushing the inner tank 1 of the toilet; in addition, since the first flushing surface 11 and the second flushing surface 12 have different inclination angles, the water flow converges downward when flowing through the flushing surfaces, thereby solving the problem that in the previous flushing process, the water flow idles in the inner tank 1 of the toilet and is difficult to discharge the dirt into the sewage pipeline 2, and the multiple rotations of the water flow also cause an increase in noise; finally, the first water flow 01 and the second water flow 02 respectively flush along the first flushing surface 11 and the second flushing surface 12 to generate vortices, the first water flow 01 and the second water flow 02 are combined into a third water flow 03 with higher potential energy at the bottom of the rear end of the inner tank 1, and since the water collecting part 13 is located at the upper part of the water seal surface 14 of the toilet, the third water flow 03 can flush away the residues around the water seal surface 14 and is directed to the sewage pipeline under the action of a larger flushing force, and the concentrated water flow can more effectively push the dirt into the sewage pipeline 2, thereby reducing the risk of blockage.

[0044] Compared with the traditional jet flushing siphon toilet (refer to Figure 1Compared with the prior art, the toilet of the utility model cancels the structure of the spray hole 9, optimizes the position and water outlet direction of the flushing hole, and uses the special design of the inner container wall to guide the water flow to generate vortex and gather into water flow with higher pushing force to push the dirt into the sewage pipeline 2, so as to replace the spray hole to push the dirt into the sewage pipeline 2 by spraying water column. In addition, due to the cancellation of the structure of the spray hole, the sound is weakened during the flushing process of the toilet, and the embarrassing situation of the user caused by too loud flushing sound is avoided.

[0045] Further, a line between the topmost end and the lowest end of the first flushing surface 11 and a horizontal plane forms a first angle;

[0046] The second flushing surface 12 is an arc surface concave to the bottom, a line between the topmost end of the second flushing surface 12 and the vertical middle end and a horizontal plane forms a second angle, and a line between the vertical direction of the second flushing surface 12 and the lowest end and the horizontal plane forms a third angle;

[0047] The second angle is greater than the first angle, and the first angle is greater than the third angle.

[0048] The first flushing surface 11 is designed as an inclined surface forming a certain angle (the first angle) with the horizontal plane, which helps the water flow to form downward force when flushing, and more effectively flushes the dirt from the inner container wall. The second flushing surface 12 is designed as an arc surface concave to the bottom of the inner container 1, and a line between the topmost end of the second flushing surface 12 and the vertical middle end, and a line between the vertical middle end and the lowest end form different angles (the second angle and the third angle) with the horizontal plane. This design not only increases the contact area of the water flow with the inner container wall, but also guides the water flow to form a stronger vortex effect through the change of the angle, so as to more effectively roll the dirt into the water flow and flush it to the sewage pipeline.

[0049] By optimizing the angle design of the flushing surface, the water flow can form a more smooth flow path when flushing the inner container wall, reducing the noise generated when the water flow impacts the inner container wall. At the same time, since the water flow forms a vortex effect during the flushing process, this flow mode itself also helps to reduce the generation of noise, further improving the mute performance of the toilet.

[0050] Further, the ratio of the water outlet amount of the first flushing hole 31 and the second flushing hole 32 is 7:3.

[0051] The first flushing hole 31 and the second flushing hole 32 have a water volume of 73 / 100. (The water volume of the first flushing hole 31 is about 70% of the total flushing water volume, and the water volume of the second flushing hole 32 is about 30% of the total flushing water volume. When the first water flow 01 and the second water flow 02 converge into the third water flow 03, the third water flow 03 can converge the two water flows into a water flow with greater energy. Therefore, the third water flow 03 can effectively introduce the water seal surface 14 of the inner container, so that there is no residual on the circumference of the water seal surface 14. At the same time, the third water flow 03 is formed by the convergence of the first water flow 01 and the second water flow 02, and the vortex formed can gather the dirt together and flush it into the pollution inlet 201.

[0052] Further, the first angle is in the range of 20°-30°, the second angle is in the range of 45°-65°, and the third angle is in the range of 10°-20°.

[0053] By limiting the first angle to the range of 20°-30°, it can be ensured that the water flow forms a moderate downward flushing force on the first flushing surface 11, which will not be too strong to increase noise, nor too weak to affect the flushing effect. The second angle of the upper arc surface (the bending arc of the top and middle) of the second flushing surface 12 is set in the range of 45°-65°, and the third angle of the lower arc surface (the bending arc of the middle and bottom) is set in the range of 20°-35°. Such design can fully utilize the advantages of the arc surface of the second flushing surface 12, guide the water flow to form a strong vortex effect, and at the same time ensure that the water flow will not be too dispersed during the flushing process, so as to more effectively roll the dirt into the water flow. It helps to maintain a certain flushing intensity when the water flow approaches the bottom of the inner container, ensuring that the dirt can be smoothly pushed to the pollution pipeline 2.

[0054] It is worth noting that the angle of the flushing surface not only helps to improve the flushing effect, but also to a certain extent reduces the waste of water resources. By optimizing the flushing path and intensity of the water flow, the water flow can be further reduced under the premise of maintaining the same flushing effect, realizing more water-saving performance.

[0055] Further, the pollution pipeline 2 includes a pollution inlet section 21, a siphon section 22, and a pollution outlet section 23.

[0056] The front part of the pollution inlet section 21 is connected with the bottom of the inner container 1, the rear part of the pollution inlet section 21 is connected with the front part of the siphon section 22, the rear part of the siphon section 22 is connected with the front part of the pollution outlet section 23, and the rear part of the pollution outlet section 23 is connected with an external pollution collection pipe.

[0057] The lower pipe wall of the front part of the pollution inlet section 21 is formed with a third inclined surface 211, and the line between the topmost end and the lowest end of the third inclined surface 211 and the horizontal plane forms a fourth angle, which is greater than the third angle.

[0058] By subdividing the drain pipe 2 into the inlet section 21, the siphon section 22, and the drain section 23, the flow path of the dirt can be more precisely controlled. The inlet section 21 is responsible for receiving the dirt flushed down from the inner container 1, the siphon section 22 uses the siphon principle to suck the dirt into the pipe, and the drain section 23 discharges the dirt to the external collecting pipe. This segmented design helps to improve the efficiency of the drain and ensures that the dirt can be smoothly discharged.

[0059] Further, the front pipe wall of the inlet section 21 is formed with a third inclined surface 211, and the fourth angle is greater than the third angle. This design allows the dirt flushed down from the inner container to be subjected to greater flushing force when it contacts the third inclined surface. This design helps to more effectively push the dirt into the siphon section 22, reducing the residence time in the inlet section 21 and thus reducing the risk of clogging.

[0060] Furthermore, the inlet section 21 is connected to the inner container 1 at an inlet opening 201, the inlet section 21 is connected to the siphon section 22 at a lowest point 202 of the inlet section 21, the siphon section 22 is provided with a highest point 203, and the siphon section 22 is connected to the drain section 23 at a drain opening 204.

[0061] The position of the inlet opening 201 is higher than the position of the lowest point 202, and the position of the highest point 203 is higher than the position of the lowest point 202.

[0062] By designing the connection between the inlet section 21 and the inner container 1 as an inlet opening 201 and ensuring that its position is higher than the lowest point 202 of the inlet section 21, this design allows the dirt flushed down from the inner container 1 to flow more smoothly into the inlet section under the action of gravity and flow downward along the pipe. This design helps to reduce the residence time of the dirt at the inlet opening 201, reduces the risk of clogging, and enhances the flushing effect.

[0063] The connection between the inlet section 21 and the siphon section 22 is the lowest point 202 of the inlet section 21, and the highest point 203 of the siphon section 22 is higher than the lowest point 202, even higher than the position of the inlet opening 201. This layout can more effectively utilize the siphon principle. When water flows through the siphon section 22, a negative pressure area is formed, attracting dirt and water flow into the pipe. The setting of the highest point 203 helps to ensure that sufficient negative pressure is formed during siphoning, improving siphoning efficiency. This design not only helps to improve the drainage capacity, but also further reduces the water flow while maintaining the same flushing effect, achieving more water-saving performance.

[0064] Optimizing the design of the water flow path and the siphon section helps to reduce the noise generated by the water flow during flushing and sewage discharge. By ensuring a reasonable layout between the sewage inlet, the lowest point, and the highest point, a smoother flow path can be formed for the water flow in the pipe, reducing the noise generated when the water flow hits the pipe wall. This design helps to further improve the noise reduction performance of the toilet, providing a more comfortable user experience.

[0065] Further, the siphon section 22 comprises a first section 221 and a second section 222;

[0066] The first section 221 is the part from the lowest point 202 to the highest point 203, and the first section 221 is arranged upwardly from front to back;

[0067] The second section 222 is the part from the highest point 203 to the sewage outlet 204, and the second section 222 is arranged downwardly from back to front.

[0068] Subdividing the siphon section 22 into the first section 221 and the second section 222, and designing them as upwardly inclined from front to back and downwardly inclined from back to front respectively, helps to optimize the siphon process. In the first section 221, the water flow gradually accelerates as it rises in the pipe, forming a strong water flow force that helps to push the sewage more efficiently towards the highest point 203. In the second section 222, the water flow accelerates downward under the action of gravity, forming a strong flushing force that quickly flushes the sewage out of the sewage outlet 204. This design can significantly improve the sewage discharge efficiency and ensure that the sewage is completely flushed out of the toilet.

[0069] By optimizing the layout and design of the siphon section 22, the siphon principle can be more effectively utilized. In the first section 221, the rising process of the water flow helps to form a negative pressure area, attracting more water flow and sewage into the pipe; in the second section 222, the accelerated falling process of the water flow can generate greater flushing force, ensuring that the sewage is smoothly flushed out. This design not only helps to improve the sewage discharge capacity, but also further reduces the water flow while maintaining the same flushing effect, achieving more water-saving performance.

[0070] Further, the pipe diameter of the sewage inlet section 21 is smaller than the pipe diameter of the siphon section 22, and the pipe diameter of the sewage discharge section 23 is smaller than the pipe diameter of the siphon section 22;

[0071] The pipe diameter of the sewage pipe 2 is greater than 55 mm.

[0072] The pipe diameter of the pollution inlet section 21 is smaller than that of the siphon section 22. This design allows the water flow to be compressed before entering the siphon section 22, thereby increasing the flow rate and impact force of the water flow. This change helps to form a stronger negative pressure effect in the siphon section 22, more effectively sucking and flushing away the pollutants. At the same time, the pipe diameter of the pollution outlet section 23 is also smaller than that of the siphon section 22, which helps to maintain the stability and concentration of the water flow during the pollution discharge process, ensuring that the pollutants can be smoothly discharged and reducing the risk of blockage.

[0073] Further explanation, the larger pipe diameter of the siphon section 22 helps to form a larger negative pressure area during the siphoning process, thereby attracting more water flow and pollutants into the pipeline. This design can significantly improve the siphoning efficiency, so that the toilet can discharge pollutants more quickly and thoroughly during flushing.

[0074] By optimizing the pipe diameter design of the pollution discharge pipeline 2, the pollution discharge capacity of the toilet is significantly improved. The pipe diameter of the pollution discharge pipeline 2 is greater than 55 mm, which helps to prevent blockage. The larger pipe diameter can reduce the residence time of pollutants in the pipeline and reduce the risk of blockage. At the same time, the larger pipe diameter also makes it easier to clean and unblock the pipeline.

[0075] Further, the water outlet direction of the first flushing hole 31 is forward, and the water outlet direction of the second flushing hole 32 is toward the first flushing hole 31.

[0076] The water outlet direction of the first flushing hole 31 is forward and tangent to the flushing ring channel 3, which allows the water flow to be evenly distributed along the tangent direction of the flushing ring channel 1. At the same time, the water outlet direction of the second flushing hole 32 is toward the first flushing hole 31, further enhancing the uniformity and coverage of the water flow, and avoiding the inconsistency of the two flushing water flow directions, which leads to mutual collision, weakening the potential energy of the water flow and weakening the cleaning effect of flushing on the toilet liner.

[0077] Further, the inner liner 1 and the flushing ring channel 3 are integrally formed.

[0078] The design of the inner liner 1 and the flushing ring channel 3 being integrally formed makes the overall structure of the toilet more stable. The integrally formed design helps to reduce the noise generated during the flushing process. Since the inner liner and the flushing ring channel are seamlessly connected, the impact and vibration that may occur when the water flow passes through the connection is reduced, thereby reducing the noise level. This design makes the toilet quieter during flushing, providing a more comfortable user experience.

These descriptions are only for explaining the principles of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way. Based on the explanations herein, other specific embodiments of the present application can be conceived by those skilled in the art without creative efforts, and these embodiments will all fall within the protection scope of the present application.
