[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0025] In order to solve the technical problem that a gap is easily formed between a floor drain and the ground due to long-term corrosion, thereby causing water seepage in the bathroom, the utility model provides a bathroom drainage structure that can prevent the gap between the floor drain and the ground from causing water seepage in the bathroom.
[0026] It should be noted that the bathroom drainage structure described in the utility model is used for but not limited to bathrooms, etc. For the convenience of explanation, in the utility model, only a bathroom drainage structure applied to the bathroom is used as an example for explanation. The principle of applying a bathroom drainage structure to other types of equipment is essentially the same as the principle applied to the bathroom, and will not be repeated here.
[0027] See also Figure 1 - Figure 2 ,in Figure 1 This is a structural schematic diagram of a bathroom drainage structure in an embodiment of the utility model. A bathroom drainage structure includes a waterproof structure 1, an inlet pipe 2, a drain pipe 3 and a downpipe 4. The waterproof structure 1 includes a bottom plate 11 and a waterproof layer 12. The bottom plate 11 is installed on the top of the waterproof layer 12. The bottom plate 11 is provided with a first through hole 111, and the waterproof layer 12 is provided with a second through hole 121. The first through hole 111 and the second through hole 121 are coaxial. An annular groove 112 is provided around the bottom end of the first through hole 111. The inlet pipe 2 is fixedly sleeved in the first through hole 111, and the drain pipe 3 is fixedly sleeved in the second through hole 121, and the top of the drain pipe 3 is embedded in the annular groove 112. The downpipe 4 is located at the bottom end of the drain pipe 3, the downpipe 4 is coaxial with the drain pipe 3, and the diameter of the downpipe 4 is larger than the diameter of the drain pipe 3.
[0028] In this embodiment, a ring groove 112 is provided around the bottom end of the first through hole 111. When water leaks through the gap between the water inlet pipe 2 and the floor, the leaked water will drip along the gap into the drain pipe 3. The leaked water cannot pass through the ring groove 112 to wet the wall outside the drain pipe 3. The ring groove 112 plays an effective blocking role, thereby avoiding the seepage of water in the bathroom. Further, since the diameter of the sewer pipe 4 is larger than that of the drain pipe 3, the leaked water in the gap between the drain pipe 3 and the waterproof layer 12 can fall into the sewer pipe 4, further improving the water seepage prevention ability of the bathroom.
[0029] During normal use, the waste water sequentially passes through the water inlet pipe 2, the drain pipe 3 and the sewer pipe 4; when there is a gap leakage between the water inlet pipe 2 and the bottom plate 11, the waste water will sequentially pass through the first through hole 111 and the ring groove 112 along the gap and then drip into the drain pipe 3. When there is a leakage between the drain pipe 3 and the waterproof layer 12, the waste water will drip into the sewer pipe 4.
[0030] Furthermore, in order to prevent gaps from being formed between the water inlet pipe 2 and the first through hole 111 and between the drain pipe 3 and the second through hole 121 to cause water leakage, waterproof glue is filled between the water inlet pipe 2 and the first through hole 111 and between the drain pipe 3 and the second through hole 121.
[0031] In one of the embodiments, please refer to Figure 1 - Figure 2 , a support rod 21 is fixedly connected between the outer wall of the bottom end of the water inlet pipe 2 and the inner wall of the drain pipe 3, and the top end of the water inlet pipe 2 is fixedly sleeved in the first through hole 111.
[0032] In this embodiment, the number of the support rods 21 is three, and they are evenly distributed around the water inlet pipe 2 for supporting the water inlet pipe 2 to be suspended inside the drain pipe 3. The drain pipe 3 and the water inlet pipe 2 are coaxially arranged, and the part of the water inlet pipe 2 that extends above the drain pipe 3 is fixedly sleeved in the first through hole 111.
[0033] Furthermore, the shape of the support rod 21 is preferably a cylinder, which can effectively prevent water from accumulating at the top of the support rod 21.
[0034] In one of the embodiments, please refer to Figure 1 - Figure 2 , a floor drain 5 is installed at the top end of the water inlet pipe 2.
[0035] In this embodiment, the function of the floor drain 5 is to drain water and isolate the smell in the sewer pipe 4 from entering the room. The floor drain 5 is located at the lowest point of the floor slab 11. The water in the bathroom converges to the floor drain 5 and is then drained by the floor drain 5. At the same time, it can also filter out impurities such as hair in the waste water.
[0036] In one of the embodiments, please refer to Figure 1 - Figure 2 , the cross section of the ring groove 112 is a right triangle, and the inclined surface of the ring groove 112 is adjacent to the outer wall of the water inlet pipe 2.
[0037] In this embodiment, when water leaks between the floor drain 5 and the ground, the wastewater flows to the annular groove 112 and can quickly drip down along the inclined surface into the drain pipe 3, preventing the wastewater from adhering to the bottom plate 11 for a long time and corroding the bottom plate 11. At the same time, the inclined surface of the annular groove 112 is adjacent to the outer wall of the water inlet pipe 2, which can guide the wastewater into the drain pipe 3 and prevent the wastewater from soaking the walls of other parts.
[0038] Furthermore, the outer diameter of the annular groove 112 is the same as the inner diameter of the second through hole 121, facilitating the top of the drain pipe 3 to be fixedly embedded in the annular groove 112.
[0039] In one embodiment, please refer to Figure 1 - Figure 2 , the bottom end of the drain pipe 3 is fixedly connected to a sewer pipe 4, and the sewer pipe 4 is communicated with the external drainage system.
[0040] In this embodiment, the diameter of the drain pipe 3 is too large to be adapted to the external drainage system. Therefore, it is necessary to connect to the external drainage system through the sewer pipe 4.
[0041] In one embodiment, please refer to Figure 1 - Figure 2 , the top end of the sewer pipe 4 is fixedly connected to a funnel 41, and the inner diameter of the top end of the funnel 41 is larger than the inner diameter of the drain pipe 3.
[0042] In this embodiment, the funnel 41 can effectively ensure that the water leakage between the drain pipe 3 and the waterproof layer 12 can fall into the sewer pipe 4, preventing water seepage in the bathroom.
[0043] In one embodiment, please refer to Figure 1 - Figure 2 , the bottom of the waterproof layer 12 is fixedly connected to a caisson 13, the caisson 13 is provided with a third through hole 131, the first through hole 111, the second through hole 121 and the third through hole 131 are coaxial, and the sewer pipe 4 is fixedly sleeved on the third through hole 131.
[0044] In this embodiment, the aperture of the third through hole 131 is smaller than the aperture of the second through hole 121. The function of the third through hole 131 is to connect to the external drainage system, and a sewer pipe 4 matching the external drainage system is required. The outer wall of the sewer pipe 4 is fixedly connected to the inner wall of the third through hole 131.
[0045] In one embodiment, please refer to Figure 1 - Figure 2 , the waterproof layer 12 includes a rubber layer 122, and the rubber layer 122 is laid under the bottom plate 11.
[0046] In this embodiment, the rubber layer 122 is for improving the waterproof effect of the bathroom and preventing water seepage in the bathroom.
[0047] In one embodiment, please refer to Figure 1 - Figure 2, the waterproof layer 12 further includes a ceramsite layer 123, and the ceramsite layer 123 is laid between the rubber layer 122 and the caisson 13.
[0048] In this embodiment, the function of the ceramsite layer 123 is to further improve the waterproof effect of the toilet and prevent water seepage in the toilet.
[0049] In one of the embodiments, please refer to Figure 1 - Figure 2 , the top of the bottom plate 11 is funnel-shaped.
[0050] In this embodiment, the first through hole 111 is the lowest point of the top of the bottom plate 11, and the other surfaces of the top of the bottom plate 11 are inclined towards the first through hole 111, facilitating the accumulated water on the bottom plate 11 to flow quickly towards the first through hole 111.
[0051] To better understand the present utility model, the following is a detailed description of the technical solution of the present utility model in conjunction with Figure 1 to Figure 2 :
[0052] During normal use, the wastewater sequentially passes through the floor drain 5, the water inlet pipe 2, the drain pipe 3 and the sewer pipe 4 and then drains into the external drainage system;
[0053] When there is a gap leakage between the water inlet pipe 2 and the bottom plate 11, the wastewater will sequentially pass through the first through hole 111 and the annular groove 112 along the gap and then drip onto the drain pipe 3 along the inclined surface of the annular groove 112. The leakage cannot pass through the annular groove 112 to wet the wall outside the drain pipe 3. The annular groove 112 plays an effective blocking role, thereby preventing water seepage in the toilet. Moreover, since the diameter of the sewer pipe 4 is larger than that of the drain pipe 3, the leakage from the gap between the drain pipe 3 and the waterproof layer 12 can fall into the sewer pipe 4, further improving the water seepage prevention ability of the toilet.
[0054] The above specific embodiments of the present utility model do not constitute a limitation on the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model should be included within the protection scope of the claims of the present utility model.
