AI Technical Summary
In the rear sewage discharge module of the existing flip-type sewage discharge toilet, the sewage discharge pipe is easily stuck by dirt, resulting in the inability to rotate and the dirt is not effectively discharged.
A sewage pipe is designed, provided with a sewage inlet at the front side and a sewage outlet at the upper end. The sewage pipe can rotate between an initial position and a sewage discharge position relative to the toilet body about the central axis of the sewage inlet. The sewage discharge pipe includes a pipe main body and a flow guide rib. The flow guide rib extends in an inclined downward direction. When the pipe main body rotates, it faces the side facing away from the flow guide rib to ensure that the dirt can flow out through the flow guide rib or the gap between the pipe main body and the sewage discharge box.
Through this design, the sewage discharge pipe can be discharged through the gap between the dirt when the dirt size is small. When the dirt size is large, it can be discharged along the large gap between the main body of the pipe and the sewage box, avoiding the problem of the sewage discharge pipe being stuck, ensuring the normal rotation of the sewage discharge pipe and the effective discharge of the dirt.

DETAILED DESCRIPTION
[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.
[0036] The embodiment of the present application provides a sewage pipe, such as Figure 1-Figure 3 As shown, the sewage pipe 1 is provided with a sewage inlet 15 located at the front side and a sewage outlet 16 located at the upper end, and the sewage inlet 15 is arranged to be connected to the sewage outlet 411 of the toilet body 4; wherein, the sewage pipe 1 is arranged to be able to rotate between an initial position and a sewage discharge position around the central axis of the sewage inlet 15 relative to the toilet body;
[0037] The sewage pipe 1 includes a pipe body 11, which is configured to be installed in the sewage box 2, wherein a flow guide rib 14 is further provided on the outer wall surface of one side of the pipe body 11, and the flow guide rib 14 extends from the first end to the second end in an inclined downward direction, and the pipe body 11 is configured to rotate toward the side away from the flow guide rib 14 to reach the sewage discharge position. That is, when the sewage pipe 1 is installed in the sewage box 2, the flow guide rib 14 is located on the side of the pipe body 11 away from the discharge port 211 of the sewage box 2, so that the pipe body 11 rotates toward the side away from the flow guide rib 14 to reach the sewage discharge position to discharge sewage to the discharge port 211.
[0038] The directions of the sewage pipe 1 such as "front", "rear", "up", and "down" described in this article refer to the directions when the sewage pipe 1 is installed on the toilet body and is in the initial position.
[0039] In the technical solution provided in the present application, the sewage pipe 1 is applied to a toilet, and when waste flows out from the sewage outlet 16 of the sewage pipe 1 to the side of the pipe body 11 having the guide rib 14, when the waste size is small, it can flow downward from the gap between the sewage box 2 and the guide rib 14 to the bottom of the pipe body 11, and then flow from the bottom to the discharge port 211. When the waste size is larger than the gap between the guide rib 14 and the sewage box 2, the waste can flow along the guide rib 14 to a position where the gap between the pipe body 11 and the sewage box 2 is larger, so that the larger waste can flow from the larger gap between the pipe body 11 and the sewage box 2 to the discharge port 211, thereby solving the problem that the sewage pipe 1 is stuck by waste and cannot rotate.
[0040] refer to Fig.10 and Fig.11 In the example shown, when the pipe body 11 is located in the sewage box 2, the guide rib 14 is located on the side of the pipe body 11 away from the discharge port 211. When the pipe body 11 rotates in the direction away from the guide rib 14 and reaches the sewage discharge position, the sewage discharge port 16 can pour the sewage into the discharge port 211 of the sewage box 2. In this example, the distance E between the guide rib 14 and the sewage box 2 is smaller than the distance F between the bottom of the pipe body 11 and the sewage box 2. When the size of the sewage flowing out of the sewage discharge port 16 to the side of the pipe body 11 with the guide rib 14 is smaller than the distance E, it can flow downward through the gap between the guide rib 14 and the sewage box 2, and then flow from the gap between the bottom of the pipe body 11 and the sewage box 2 to the discharge port 211. When the size of the sewage is larger than the distance E, the sewage flows along the guide rib 14, and the sewage is guided to flow from the larger gap between the pipe body 11 and the sewage box 2 to the discharge port 211.
[0041] In one embodiment, if Figure 1-Figure 3 As shown, the sewage pipe 1 includes an annular connection portion 12 arranged around the sewage inlet 15, a first end of the guide rib 14 is connected to the annular connection portion 12, and a second end is located at a rear lower position of the pipe body 11. The gap between the rear lower position of the pipe body 11 and the sewage box 2 is relatively large, and sewage can easily flow from this position to the discharge port 211 of the sewage box 2.
[0042] Figure 2 In the example shown, the annular connecting portion 12 is formed with a boss protruding from the outer surface of the pipe body 11 , and the guide rib 14 extends from the rear side of the boss away from the sewage inlet 15 toward the rear lower position of the pipe body 11 .
[0043] It is understandable that the positions of the first end and the second end of the guide rib 14 are not limited to those described above, as long as the dirt can be guided downward to the larger gap between the pipe body 11 and the dirt discharge box 2 .
[0044] In one embodiment, the guide rib 14 includes a first guide portion 141 and a second guide portion 142 which are sequentially arranged in an inclined downward direction, and the inclination angle of the second guide portion 142 is greater than that of the first guide portion 141. The inclination angle of the second guide portion 142 is set to be greater than that of the first guide portion 141, so that when the waste flows from the first guide portion 141 to the second guide portion 142, the waste can flow down quickly, which can not only prevent the waste from accumulating on the guide rib 14, but also increase the flow speed through potential energy, so that the waste can quickly flow to the discharge port 211 in the gap between the pipe body 11 and the waste discharge box 2.
[0045] exist Figure 1 In the example shown, the pipe body 11 includes a front side wall 111, a rear side wall 113, and a first side wall 112 and a second side wall 114 located on both sides. The front side wall 111, the rear side wall 113, the first side wall 112 and the second side wall 114 form a cylindrical structure, and also include a bottom wall 115 that blocks the bottom of the cylindrical structure. In order to improve the sewage discharge performance of the pipe body 11 and prevent residual dirt in the pipe body 11, the connection between the side walls is smoothly transitioned, and the bottom wall 115 is formed into a concave arc structure to prevent residual dirt. In this example, in order to facilitate installation and save installation space, the front side wall 111 is roughly flat, and a sewage inlet 15 is arranged on the front side wall 111. The sewage inlet 15 is provided with an annular connecting portion 12 for connecting with the sewage box 2 or the sewage outlet of the toilet. The guide rib 14 is arranged on the first side wall 112, and extends obliquely downward and backward from the annular connecting portion 12 to the bottom wall 115, and the guide rib 14 is further bent downward at a position close to the bottom wall 115.
[0046] The sewage pipe 1 further includes a rotation connection portion 13 disposed on the rear side wall 113 . The rotation connection portion 13 is used to be connected to the driving mechanism 3 so as to drive the sewage pipe 1 to rotate through the driving mechanism 3 .
[0047] In one embodiment, if Figure 4 As shown, an overflow port 17 is provided on the side wall of the pipe body 11 , and the overflow port 17 is located below the sewage outlet 16 and above the sewage inlet 15 .
[0048] The overflow port 17 is located above the sewage inlet 15, which can ensure that a water seal can be formed in the toilet. Since the overflow port 17 is located below the sewage outlet 16, the liquid above the overflow port 17 in the sewage pipe 1 will flow outward through the overflow port 17 until the water cover is flush with the lowest point of the overflow port 17. Therefore, the overflow port 17 can play a role in lowering the height of the water cover position, preventing the user from splashing water when using the toilet, which is conducive to improving the user's experience. When sewage needs to be discharged, water begins to flow into the toilet body 4. Since the water inlet flow rate is much greater than the overflow flow rate of the overflow port 17, the water cover in the toilet will quickly rise to the position of the sewage outlet 16, thereby increasing the flushing water volume and the gravitational potential energy of the flushing water. Then the sewage pipe 1 is rotated downward to the sewage discharge position, and a relatively large amount of water and gravitational potential energy can be used to achieve a better sewage flushing effect. Therefore, this solution adds an overflow port 17 to the sewage pipe 1, and the overflow port 17 can be used to control the height of the toilet water cover, so that the toilet water cover is at a relatively low position in the non-sewage state, thereby avoiding the problem of the toilet water cover being too high, which causes splashes when the user uses the toilet, while in the sewage state, a larger amount of water is used to flush the toilet.
[0049] Figure 4 In the example shown, the overflow port 17 is located on the longitudinal centerline of the sewage pipe 1, which refers to the vertical centerline passing through the center of the sewage inlet 15 when the pipe body 11 is in the initial position (not tilted relative to the toilet body). Figure 1 In the example shown, the overflow port 17 is arranged on the front side wall 111 of the pipe body 11 having the sewage inlet 15. Of course, in order to make the overflow port 17 arranged on the longitudinal center line of the sewage pipe 1, the overflow port 17 can also be arranged on the rear side wall 113 of the pipe body 11 opposite to the front side wall 111.
[0050] When the module consisting of the sewage pipe 1 and the sewage box 2 is assembled with the toilet body 4, there will be a deviation in the rotation direction of the sewage pipe 1, that is, the sewage pipe 1 is not completely vertical in the initial state, but has a certain inclination, which will cause the overflow port 17 to be tilted, and the inclination of the overflow port 17 will cause the height of the toilet water cover to deviate. In this solution, the overflow port 17 is set on the longitudinal center line of the pipe body 11, and when the sewage pipe 1 is deflected relative to the toilet body 4, the height position deviation of the overflow port 17 in the tilted state and the non-tilted state can be reduced, thereby reducing the impact on the height deviation of the toilet water cover.
[0051] refer to Fig.12 As shown, the sewage pipe 1 at position b is in a non-deflected state relative to the toilet body 4, the sewage pipe 1 at position a is deflected to the left relative to the toilet body 4, and the sewage pipe 1 at position c is deflected to the right relative to the toilet body 4.
[0052] Fig.12It is shown in the figure that the sewage pipe 1 is provided with a first overflow port 17a on the central axis, and a second overflow port 17b is provided on the side wall on one side. The height deviation of the first overflow port 17a at positions a and c compared with the first overflow port 17a at position b is J; the height deviation of the second overflow port 17b at position a compared with the second overflow port 17b at position b is I, and the height deviation of the second overflow port 17b at position c compared with the second overflow port 17b at position b is H. Both I and H are greater than J. It can be seen that when the sewage pipe 1 is installed obliquely, the position deviation of the first overflow port 17a at the longitudinal center line is the smallest, thereby minimizing the impact on the toilet water cover. Therefore, setting the overflow port 17 on the longitudinal center line of the sewage pipe 1 can reduce the impact on the toilet water cover.
[0053] In one example, reference Figure 4 , the overflow port 17 is square, the length A of the overflow port 17 in the horizontal direction is 5-30mm, and the width B in the vertical direction is 2-10mm. The size of the overflow port 17 affects the overflow speed, the rising speed of the water cover, the strength of the sewage pipe 1, etc. If the length and width of the overflow port 17 are too large, the overflow speed will be too fast, which will increase the water consumption required for the toilet water seal to rise to the sewage outlet 16, and will cause the water cover to rise at a slower speed, which will also affect the strength of the sewage pipe 1. Limiting the height of the overflow port 17 to the range of 2-10mm and limiting the width of the overflow port 17 to the range of 5-30mm can take into account the overflow speed of the overflow port 17, the rising speed of the water cover and the strength of the sewage pipe 1. Of course, the length and width of the overflow port 17 are not limited to the above ranges and can be adjusted as needed.
[0054] In one example, the distance C between the overflow port 17 and the center of the sewage inlet 15 is 70-116 mm. Setting the distance C between the overflow port 17 and the center of the sewage inlet 15 to 70-116 mm can ensure that the height of the water cover is not too high to cause splashing when entering the toilet, and not too low to cause a poor water seal effect and cause odor.
[0055] In one embodiment, the area S of the sewage outlet 16 is 25-65 cm 2 The area of the sewage outlet 16 needs to be set appropriately, because the size of the sewage outlet 16 not only affects the discharge of waste, but also affects the splashing of water from the sewage outlet 16 when flushing the toilet.
[0056] The embodiment of the present application also provides a sewage discharge module, such as Figure 5-Figure 7As shown, it includes: a sewage box 2 and a sewage pipe 1 as described above; the sewage box 2 is configured to be fixed to the toilet body 4, and the pipe body 11 of the sewage pipe 1 is installed in the sewage box 2. When the sewage pipe 1 is rotated to the sewage discharge position, the sewage outlet 16 can pour the sewage into the discharge port 211 of the sewage box 2.
[0057] In one embodiment, at the second end of the guide rib 14, the distance between the pipe body 11 and the sewage box 2 is greater than the distance between the bottom of the pipe body 11 and the sewage box 2, so that when the guide rib 14 guides the sewage to the position of the second end, the sewage can flow from the gap between the pipe body 11 and the sewage box 2 to the discharge port 211.
[0058] In one embodiment, the distance E between the guide rib 14 and the sewage box 2 is smaller than the distance F between the bottom of the pipe body 11 and the sewage box 2, so that the dirt flowing from the gap between the guide rib 14 and the sewage box 2 to the bottom can flow from the gap between the bottom of the pipe body 11 and the sewage box 2 to the discharge port 211.
[0059] In one example, if Figure 6 and Figure 7 As shown, the sewage box 2 includes a box body 21 and a box cover 22. The box body 21 and the box cover 22 are buckled together to form a space for installing the pipe body 11. The box body 21 and the box cover 22 can be sealed by a sealing ring 23. Among them, the front side of the box body 21 is provided with a connecting port, and the sewage outlet 15 of the sewage pipe 1 is connected to the sewage outlet 411 of the toilet body 4 through the connecting port. Figure 6 (Combined Figure 8 and Fig. 9 ), an annular connection part 12 is provided at the sewage outlet 15 of the sewage pipe 1, the annular connection part 12 is connected to the structure at the connection port of the box body 21, and a first sealing member 24 is provided between the annular connection part 12 and the box body 21, and a second sealing member 25 is provided between the sewage box 2 and the sewage outlet 411 of the toilet body to achieve a sealed connection. An opening is provided on the box cover 22, and the rotating connection part 13 of the sewage pipe 1 is connected to the driving mechanism 3 through the opening on the box cover 22, so that the sewage pipe 1 is driven by the driving mechanism 3 to rotate between the initial position and the sewage discharge position.
[0060] An embodiment of the present application also provides a toilet, comprising: a toilet body 4 and the sewage discharge module as described above; wherein the toilet body 4 is provided with a pelvic cavity 41 having a sewage outlet 411 , and the sewage inlet 15 of the sewage discharge pipe 1 is connected to the sewage outlet 411 of the pelvic cavity 41 .
[0061] The sewage module and toilet provided in the embodiments of the present application include the sewage pipe 1 of any one of the above embodiments, and thus have all the beneficial effects of any of the above embodiments, which will not be repeated here.
