Description

Technical Field

[0001] This application relates to the technical field of toilet drainage, and in particular to a drainage structure for building toilets. Background Art

[0002] Building toilets are mainly divided into sunken and non-sunken types. The sunken toilet, also known as a sunken box toilet, mainly refers to the overall sinking of the toilet structure layer by a certain height from the corresponding floor during the main construction, so that the horizontal drainage pipes in the toilet are buried therein, and then backfilled with lightweight ceramsite, and finally a waterproof floor is laid on the backfill material.

[0003] The drainage pipeline of the sunken toilet generally includes a main drainage pipe and a connecting pipe. One end of the connecting pipe is connected to the floor drain on the waterproof floor, and the other end passes through the waterproof floor and is connected to the main drainage pipe in the sunken box, so that the water on the toilet floor can converge into the main drainage pipe through the floor drain.

[0004] Due to the long-term influence of cold and hot water in the toilet, the waterproof floor is prone to water seepage. In particular, at the connection between the connecting pipe and the waterproof floor, due to the long-term influence of the thermal expansion and contraction of cold and hot water, cracks are easily generated, resulting in water seepage. When cracks occur at the connection between the waterproof floor and the connecting pipe, the water in the toilet will seep into the sunken area of the toilet through the cracks, causing water accumulation in the sunken area of the toilet. In severe cases, the accumulated water may even seep into the lower floor, causing the problem of toilet leakage. Summary of the Invention

[0005] In order to improve the problem of water accumulation in the sunken area of the toilet, this application provides a drainage structure for building toilets.

[0006] This application provides a drainage structure for building toilets, adopting the following technical solutions:

[0007] A drainage structure for building toilets includes

[0008] A main drainage pipe, a branch pipe for horizontally extending along the bottom of the sunken box is connected to the outer periphery of the main drainage pipe, and one end of the branch pipe is connected with an elbow;

[0009] A connecting pipe, the connecting pipe is coaxial with the end of the elbow away from the branch pipe, one end of the connecting pipe is used for connecting with the floor drain, and the other end extends vertically towards the bottom of the sunken box;

[0010] A joint for connecting the connecting pipe and the elbow;

[0011] Wherein, the joint includes a sleeve and a support ring, the support ring is coaxially fixed on the outer peripheral side of the sleeve, and the two ends of the sleeve are respectively connected to the connecting pipe and the elbow for rotational sealing; the outer diameter of the support ring is larger than the outer diameter of the connecting pipe, and the support ring has an internal hollow water passage cavity, and a side of the support ring away from the elbow is provided with a plurality of circumferentially distributed water inlet holes, and the plurality of water inlet holes are connected to the water passage cavity; the end of the sleeve inserted into the elbow is provided with a water outlet hole connected to the water passage cavity.

[0012] By adopting the above technical solution, when water on the bathroom floor seeps into the caisson, the accumulated water will enter the water cavity through the water inlet hole and be discharged in time through the water outlet hole, effectively reducing the possibility of bathroom leakage.

[0013] Optionally, the support ring is also provided with a water inlet pipe slidably connected to the water inlet hole, the outer peripheral side of the connecting pipe is provided with a curved groove extending in a wave shape around the circumference of the connecting pipe, and an adjustment column located in the curved groove is fixed on one side of the water inlet pipe close to the connecting pipe.

[0014] By adopting the above technical solution, the accumulated water infiltrating into the caisson can be discharged into the past cavity through the water inlet pipe. When the water inlet pipe is blocked, the water inlet pipe and the regulating column can be moved up and down along the track of the curved groove by rotating the sleeve, which has the effect of disturbing the filling layer in the caisson, thereby clearing the blocked water inlet pipe.

[0015] Optionally, a cleaning roller is further provided on the outer circumference of the connecting pipe. The cleaning roller is located at the crest or trough of the curved groove, and bristles are evenly distributed on the outer circumference of the cleaning roller.

[0016] By adopting the above technical solution, a cleaning roller with bristles is arranged on the side wall of the connecting pipe, so that when the joint rotates around the connecting pipe with the water inlet pipe, the water inlet pipe will pass under the cleaning roller and clean the garbage at the pipe mouth of the water inlet pipe, thereby further unblocking the water inlet pipe.

[0017] Optionally, an operating rod extending axially along the sleeve is fixed to one end of the sleeve away from the elbow, and the end of the operating rod away from the sleeve is located at the pipe opening of the connecting pipe, and the operating rod abuts against the inner wall of the connecting pipe.

[0018] By adopting the above technical solution, the user can use the operating rod to drive the joint to rotate through the operating rod extending to the pipe mouth of the connecting pipe to clear the water inlet pipe. At the same time, the operating rod that is in contact with the inner wall of the connecting pipe can also scrape off the attachments on the inner wall of the connecting pipe when rotating with the joint.

[0019] Optionally, two operating rods are symmetrically arranged, and a linkage rod is connected between the two operating rods. The linkage rod is located at one end of the operating rod close to the pipe opening of the connecting pipe.

[0020] By adopting the above technical solution, the setting of the two operating rods and the linkage rod can improve the stability when the joint rotates.

[0021] Optionally, a rotary seal connection is formed between the casing and the connecting pipe through a rotary seal ring.

[0022] By adopting the above technical solution, using the rotary seal ring as the rotary seal connecting piece between the casing and the connecting pipe has the advantages of simple structure and stable force.

[0023] Optionally, it further includes a diversion layer, and the diversion layer is arranged at the bottom of the caisson and slopes downward from the peripheral side of the caisson towards the elbow.

[0024] By adopting the above technical solution, the setting of the diversion layer can make the accumulated water infiltrating into the caisson converge towards the elbow, thus facilitating the convergence and discharge of the accumulated water in the caisson.

[0025] Optionally, the support ring and the casing are of an integrally formed structure.

[0026] By adopting the above technical solution, since the support ring and the casing are of an integrally formed structure, the production efficiency is effectively improved and the processing cost is reduced.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] 1. Through the setting of the joint in the present application, the accumulated water infiltrating into the caisson can be discharged in time;

[0029] 2. Through the setting of the water inlet pipe, the adjusting column and the curve groove, the water inlet hole can be effectively prevented from being blocked. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] An embodiment of the present application discloses a drainage structure for a building toilet. Refer to Figure 1 , 2 , the drainage structure of the building toilet includes a main drainage pipe 2, a connecting pipe 3 and a joint 4. A horizontally extending branch pipe 22 is connected to the outer periphery of the main drainage pipe 2. The branch pipe 22 is located at the bottom of the sunken area of the toilet, that is, the bottom of the caisson 1. One end of the branch pipe 22 away from the main drainage pipe 2 is fixedly connected with an elbow 21. The elbow 21 has a right-angled structure, and one end of the elbow 21 away from the branch pipe 22 extends vertically upward. One end of the connecting pipe 3 is connected to the floor drain on the toilet floor, and the other end extends vertically downward toward the bottom of the caisson 1 and is coaxially arranged with one end of the elbow 21 away from the branch pipe 22. And the joint 4 is used to connect the connecting pipe 3 and the elbow 21.

[0039] Refer to Figure 3 , 4 , the joint 4 includes a sleeve 6 and a support ring 5 integrally arranged on the outer peripheral side of the sleeve 6. The support ring 5 is located in the middle of the outer peripheral side of the sleeve 6. Both ends of the sleeve 6 are respectively inserted into the elbow 21 and the connecting pipe 3, and form a rotary seal with the elbow 21 and the connecting pipe 3 through rotary seals respectively.

[0040] Refer to Figure 4 , 5 , the outer diameter of the support ring 5 is larger than the outer diameter of the connecting pipe 3. The support ring 5 has a hollow water passage cavity 7 inside. The water passage cavity 7 is a ring-shaped structure coaxial with the support ring 5. A plurality of water inlet holes 8 communicating with the water passage cavity 7 are opened on one side of the support ring 5 away from the elbow 21. The plurality of water inlet holes 8 are equally spaced around the circumference of the support ring 5. One end of the sleeve 6 inserted into the elbow 21 is provided with a water outlet hole 9 communicating with the water passage cavity 7.

[0041] Refer to Figure 5 , 6The support ring 5 is also provided with a water inlet pipe 10 that is slidably connected to the water inlet hole 8. The water inlet pipe 10 and the water inlet hole 8 are both in a mutually adapted square structure. The accumulated water in the caisson 1 can be collected into the water passage chamber 7 through the water inlet pipe 10. A curved groove 11 is provided on the outer peripheral side of the connecting pipe 3 near the end of the joint 4. The curved groove 11 extends in a wavy structure around the circumference of the connecting pipe 3. An adjusting column 12 located in the curved groove 11 is fixed on the side of the water inlet pipe 10 near the connecting pipe 3. When the joint 4 rotates, the adjusting column 12 is exchanged between the crest and the trough of the curved groove 11, so that the adjusting column 12 moves up and down with the water inlet pipe 10, thereby clearing the pipe mouth of the water inlet pipe 10 and preventing the water inlet pipe 10 from being blocked. It should be noted here that when the adjusting column 12 is located at the crest or trough, there is always a water gap between the bottom of the water inlet pipe 10 and the water passage chamber 7, and the water inlet pipe 10 will never be separated from the water inlet hole 8 when it is raised or lowered.

[0042] Reference Figure 6 A cleaning roller 15 is also fixed on the outer peripheral side of the connecting pipe 3, and the axis of the cleaning roller 15 intersects perpendicularly with the axis of the connecting pipe 3. The cleaning roller 15 is located at the crest or trough of the curved groove 11, and the outer peripheral side of the cleaning roller 15 is evenly distributed with bristles 16. When the joint 4 rotates, the water inlet pipe 10 passes through the cleaning roller 15, so that the bristles 16 on the cleaning roller 15 can clean the pipe opening of the water inlet pipe 10 and remove the debris blocked at the pipe opening of the water inlet pipe 10.

[0043] Reference Figure 4 , 5 An operating rod 13 extending along the axial direction of the sleeve 6 is fixed to one end of the sleeve 6 away from the elbow 21. In this embodiment, two operating rods 13 are symmetrically arranged, and both operating rods 13 abut against the inner wall of the sleeve 6. The end of the operating rod 13 away from the sleeve 6 is located at the pipe opening of the connecting pipe 3. A linkage rod 14 is fixed between the two operating rods 13, and the linkage rod 14 is located at one end of the operating rod 13 close to the pipe opening of the connecting pipe 3. When in use, the operator only needs to rotate the linkage rod 14 to make the linkage rod 14 and the two operating rods 13 rotate with the sleeve 6. At the same time, the operating rod 13 will also scrape off the garbage attached to the inside of the connecting pipe 3 during the rotation process.

[0044] Reference Figure 2 The toilet drainage structure also includes a guide layer 17, which is laid on the bottom of the caisson 1 and is inclined downward from the circumference of the caisson 1 to the direction of the elbow 21, so that the water that penetrates into the caisson 1 can be gathered toward the direction of the elbow 21 through the guide layer 17, and enter the elbow 21 through the water inlet pipe 10 on the joint 4, and finally enter the drainage main pipe 2 through the branch pipe 22 for discharge. The guide layer 17 can be formed by pouring concrete.

[0045] The implementation principle of a building toilet drainage structure in the embodiment of the present application is:

[0046] When water seepage occurs in the bathroom, the water that seeps into the caisson 1 moves toward the elbow 21 through the guide layer 17, flows into the water chamber 7 through the water inlet pipe 10 on the joint 4, then enters the elbow 21 through the water outlet 9, and finally flows into the main drainage pipe 2 through the branch pipe 22 for discharge.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
