Description

Technical Field

[0001] This utility model relates to the field of drainage system technology, and more specifically, to a water drainer. Background Technology

[0002] Traditional in-floor drainage systems require bathrooms to accommodate floor showers and prevent odors from backflowing. This typically necessitates the installation of directly buried water-sealed floor drains and a slight reduction in the floor slab height of the structural layer. Although secondary waterproofing of the structural layer is required during construction, some floor drainage can still seep into the structural layer through the drain edges and backfill layers. Over time, this can easily lead to mold growth on the floor slab or surrounding walls. Utility Model Content

[0003] This invention provides a water drainage device to overcome the problem in the prior art where ground drainage seeps into the structural layer and is difficult to drain.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a water drainer, comprising: a water receiving tray and a water guide pipe, wherein the water receiving tray has a first water receiving groove and a second water receiving groove, the second water receiving groove is arranged around the outside of the first water receiving groove, one end of the water guide pipe has a first water guide port, the side wall of the water guide pipe near the first water guide port has a second water guide port, the first water receiving groove is connected to the first water guide port, the second water receiving groove is connected to the second water guide port, and the other end of the water guide pipe is used to connect to an external drainage system.

[0005] In the technical solution of this utility model, the water drainer is set at the bottom of the floor slab leveling layer. The first water receiving groove can receive water that seeps into the structural layer from the edge of the floor drain or the landfill layer. The water received by the first water receiving groove can enter the water pipe from the first water guide and be discharged. The second water receiving groove is arranged around the first water receiving groove. On the one hand, it can receive part of the water outside the first water receiving groove and discharge it from the second water guide, thereby increasing the water receiving area. On the other hand, when installing the water drainer, the landfill can partially cover the second water receiving groove for fixation, which helps to fix the installation position of the water drainer.

[0006] Furthermore, an annular positioning rib is provided in the middle of the water receiving tray, and the first water receiving groove is arranged around the annular positioning rib in the circumferential direction. A positioning cavity is formed inside the annular positioning rib, and the positioning cavity is used to match and fit with the bottom of the water seal pipe of the floor drain.

[0007] In this solution, the annular positioning rib is connected and fixed to the bottom of the water seal pipe of the floor drain, so that the first water receiving groove surrounds the bottom of the floor drain to receive water seeping from the edge of the floor drain, thus achieving a better drainage effect.

[0008] Furthermore, the bottom of the water receiving tray is provided with a first reinforcing rib, and the projection of the annular positioning rib on the horizontal plane falls within the projection of the first reinforcing rib on the horizontal plane.

[0009] In this solution, the first reinforcing rib can improve the deformation resistance of the first water receiving groove, reduce the deformation of the first water receiving groove caused by the connection between the annular positioning rib and the bottom of the water seal pipe of the floor drain, and reduce the impact of installation deformation on the drainage effect.

[0010] Furthermore, the thickness of the first reinforcing rib is greater than the thickness of the annular positioning rib.

[0011] In this design, a thicker first reinforcing rib is beneficial for improving the deformation resistance of the first water receiving trough.

[0012] Furthermore, there are separating ribs between the first water receiving tank and the second water receiving tank.

[0013] In this scheme, by setting partition ribs, a first water receiving groove and a second water receiving groove can be formed on the water receiving tray.

[0014] Furthermore, the bottom of the water receiving tray is provided with a second reinforcing rib, and the projection of the dividing rib on the horizontal plane falls within the projection of the second reinforcing rib on the horizontal plane.

[0015] In this design, the deformation resistance of the first water receiving tank is further improved by using a second reinforcing rib.

[0016] Furthermore, it also includes a slurry-proof cover, which is detachably connected to the top opening of the first water receiving tank.

[0017] In this solution, during the construction phase, the anti-grout cover can prevent the first water inlet trough from being filled and blocked by cement mortar, thus affecting the water guiding effect. When the construction is completed, the anti-grout cover can be removed without affecting normal use.

[0018] Furthermore, the anti-slurry cover includes an annular sealing part and a sealing plate. The sealing plate is vertically connected to one side of the annular sealing part. The annular sealing part matches and seals the first water receiving groove. The sealing plate matches and seals the first water inlet of the water guide pipe.

[0019] In this design, the annular sealing part is used to seal the first water inlet, and the sealing plate is used to seal the first water outlet to prevent cement mortar blockage.

[0020] Furthermore, the projection of the annular sealing portion onto the horizontal plane can cover the projection of the separating rib onto the horizontal plane.

[0021] In this solution, by covering the partition bars with an annular sealing part, cement mortar can be prevented from falling vertically into the first water receiving tank from the gap between the anti-grout cover and the partition bars during construction, thus avoiding cement mortar blockage.

[0022] Furthermore, the annular sealing part has an abutment part on the side facing the first water receiving tank, and the abutment part is annular and abuts against the inner wall of the partition rib.

[0023] In this design, the anti-slurry cover is tightly connected to the first water receiving tank by the abutting part abutting with the partition rib, making it easy to disassemble.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] I. The water drainer of this utility model is installed at the bottom of the floor slab leveling layer. A first water receiving groove receives water that seeps into the structural layer from the edge of the floor drain or the backfill layer. The water received in the first water receiving groove can then enter the drain pipe through the first drain outlet and be discharged. A second water receiving groove is arranged around the first water receiving groove. On the one hand, it can receive some water from the outside of the first water receiving groove and discharge it through the second drain outlet, increasing the water receiving area. On the other hand, when installing the water drainer, the backfill material can partially cover and fix the second water receiving groove, which helps to secure the installation position of the water drainer.

[0026] II. The water drain device of this utility model is fixed to the bottom of the water seal pipe of the floor drain by a ring positioning rib, so that the first water receiving groove surrounds the bottom of the floor drain to receive water seeping from the edge of the floor drain, thereby achieving a better drainage effect.

[0027] Third, the water drainer of this utility model, by setting a grout-proof cover, can prevent the first water receiving channel from being filled and blocked by cement mortar during the construction stage, thus affecting the water guiding effect. When the construction is completed, the grout-proof cover can be removed without affecting normal use. Attached Figure Description

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

[0040] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0041] Example 1

[0042] refer to Figure 1This embodiment discloses a water drainer, including a water receiving tray 1 and a water guide pipe 2. The water receiving tray 1 has a first water receiving groove 11 and a second water receiving groove 12. The second water receiving groove 12 is arranged around the outside of the first water receiving groove 11. One end of the water guide pipe 2 has a first water guide port 21. The side wall of the water guide pipe 2 near the first water guide port 21 has a second water guide port 22. The first water receiving groove 11 is connected to the first water guide port 21, and the second water receiving groove 12 is connected to the second water guide port 22. The other end of the water guide pipe 2 is used to connect to an external drainage system.

[0043] In this embodiment, the water drain is located at the bottom of the floor slab leveling layer and above the structural layer. The first water receiving groove 11 receives water that seeps into the structural layer from the edge of the floor drain or the landfill layer. The water received by the first water receiving groove 11 can then be discharged through the first water inlet 21 into the water pipe 2. The second water receiving groove 12 surrounds the first water receiving groove 11. On one hand, it receives some water from the outside of the first water receiving groove 11 and discharges it through the second water inlet 22, increasing the water receiving area. On the other hand, when installing the water drain, the landfill material can partially cover and fix the second water receiving groove 12, which helps to secure the installation position of the water drain.

[0044] Specifically, the water receiving tray 1 can be roughly disc-shaped, and both the first water receiving trough 11 and the second water receiving trough 12 are annular and concentrically arranged with the water receiving tray 1. The first water guide port 21 is located at the end of the water guide pipe 2 that is connected to the water receiving tray 1, and has a roughly circular opening. The first water guide port 21 is radially connected to the first water receiving trough 11. The second water guide port 22 is provided on both sides of the first water guide port 21, and has a roughly rectangular opening. Both sides of the water guide pipe 2 are connected to the second water receiving trough 12 through the second water guide port 22.

[0045] During installation, the drain can be fixed by burying it with cement mortar, starting from the outside of the water receiving tray 1 and moving inwards, but not exceeding the first water receiving groove 11. For example, the second water receiving groove 12 can be completely covered with cement mortar. However, due to the thermal expansion and contraction properties of cement and the drain itself, gaps may appear after the cement hardens. If only the first water receiving groove 11 is installed without the second water receiving groove 12, some water may seep into the structural layer through these gaps and cannot be drained. In this embodiment, water entering through the gaps can be drained through the second water receiving groove 12 and the second water inlet 22 into the water pipe 2, or water can overflow from the top of the second water receiving groove 12 into the first water receiving groove 11 and be drained through the first water inlet 21 into the water pipe 2. This minimizes water seepage into the structural layer and achieves better drainage. Meanwhile, by filling the second water receiving tank 12 with cement mortar, the position of the water discharge device can be stably fixed after the cement mortar solidifies, preventing the water discharge device from shifting and causing water to leak into the structural layer.

[0046] refer to Figure 1 A ring-shaped positioning rib 13 is provided in the middle of the water receiving tray 1. The first water receiving groove 11 is arranged circumferentially around the ring-shaped positioning rib 13. A positioning cavity is formed inside the ring-shaped positioning rib 13, which is used to match and fit with the bottom of the water seal pipe of the floor drain. (Reference) Figure 6 The first water inlet 11 is fixed to the bottom of the drain by the annular positioning rib 13, so that the first water inlet 11 surrounds the bottom of the drain to receive water seeping from the edge of the drain, thus achieving a better drainage effect.

[0047] In this embodiment, the height of the annular positioning rib 13 in the vertical direction can exceed the top height of the first water receiving trough 11 and the second water receiving trough 12, so that the positioning cavity has a suitable depth, allowing the positioning cavity to be stably connected to the bottom of the water seal pipe of the floor drain.

[0048] refer to Figure 4 and Figure 5 The bottom of the water receiving tray 1 is provided with a first reinforcing rib 14, and the projection of the annular positioning rib 13 on the horizontal plane falls within the projection of the first reinforcing rib 14 on the horizontal plane. In this embodiment, the first reinforcing rib 14 can improve the deformation resistance of the first water receiving groove 11, reduce the deformation of the first water receiving groove 11 caused by the connection of the annular positioning rib 13 to the bottom of the water seal pipe of the floor drain, and reduce the impact of installation deformation on the drainage effect. The first reinforcing rib 14 is arranged in a ring shape at the bottom of the water receiving tray 1.

[0049] refer to Figure 5 The thickness of the first reinforcing rib 14 is greater than the thickness of the annular positioning rib 13. In this embodiment, the greater thickness of the first reinforcing rib 14 is beneficial to improving the deformation resistance of the first water receiving tank 11.

[0050] refer to Figure 1 and Figure 4 A partition rib 15 is provided between the first water receiving trough 11 and the second water receiving trough 12. By setting the partition rib 15, the first water receiving trough 11 and the second water receiving trough 12 can be formed on the water receiving tray 1. During construction, the radial filling range of cement mortar does not exceed the position of the partition rib 15, which can prevent cement mortar from clogging the first water receiving trough 11.

[0051] refer to Figure 4 and Figure 5 The bottom of the water receiving tray 1 is provided with a second reinforcing rib 16, and the projection of the dividing rib 15 on the horizontal plane falls within the projection of the second reinforcing rib 16 on the horizontal plane. In this embodiment, the second reinforcing rib 16 further improves the deformation resistance of the first water receiving tank 11.

[0052] Water drainers can be configured in different ways. (See reference) Figure 7The water drain can be installed separately from the floor drain. In this case, the water drain is installed at the lowest point of the floor slab leveling layer, and one end of the water pipe 2 is connected separately to the drainage system to prevent water accumulation on the floor slab. (Reference) Figure 6 , Figure 8 and Figure 9 The water drain can be placed at the bottom of the floor drain to effectively collect water seeping from the edge of the floor drain. At this time, one end of the water pipe 2 is connected to the drainage system along with the floor drain.

[0053] Example 2

[0054] This embodiment is similar to Embodiment 1, except that in this embodiment, reference is used. Figure 2 as well as Figure 1 and Figure 3 The water drain also includes a grout preventer 3, which is detachably connected to the top opening of the first water receiving trough 11. During construction, the grout preventer 3 prevents the first water receiving trough 11 from being filled and blocked by cement mortar, thus affecting the water guiding effect. When construction is completed, the grout preventer 3 can be removed without affecting normal use.

[0055] refer to Figure 2 as well as Figure 1 and Figure 3 The anti-grout cover 3 includes an annular sealing part 31 and a sealing plate 32. The sealing plate 32 is vertically connected to one side of the annular sealing part 31. The annular sealing part 31 matches and seals the first water receiving groove 11, and the sealing plate 32 matches and seals the first water inlet 21 of the water guide pipe 2. In this embodiment, the annular sealing part 31 is used to seal the first water receiving groove 11, and the sealing plate 32 is used to seal the first water inlet 21 to prevent cement mortar blockage.

[0056] Specifically, the sealing plate 32 of the anti-slurry cover 3 can be higher in the vertical direction than the height of the water pipe 2. After the anti-slurry cover 3 is connected, the upper end of the sealing plate 32 will extend a section of the edge. The anti-slurry cover 3 can be removed by grabbing the edge and pulling it.

[0057] refer to Figure 4 and Figure 5 The projection of the annular sealing part 31 onto the horizontal plane can cover the projection of the partition rib 15 onto the horizontal plane. In this embodiment, by covering the partition rib 15 with the annular sealing part 31, cement mortar can be prevented from falling vertically into the first water receiving tank 11 from the gap between the anti-grout cover 3 and the partition rib 15 during construction, thus preventing cement mortar blockage. (Reference) Figure 1 In this embodiment, the outer edge of the annular sealing part 31 is aligned with the outer edge of the partition rib 15 in the vertical direction, and the lower side of the annular sealing part 31 is fitted with the upper side of the partition rib 15, which can effectively prevent cement mortar from falling into the first water receiving tank 11.

[0058] Example 3

[0059] This embodiment is similar to Embodiment 2, except that, as referenced... Figure 4 and Figure 5 The annular sealing part 31 has an abutment part 33 on the side facing the first water receiving tank 11. The abutment part 33 is annular and abuts against the inner side wall of the partition rib 15. In this embodiment, the abutment part 33 abuts against the partition rib 15, so that the anti-slurry cover 3 is tightly connected to the first water receiving tank 11, which is convenient for disassembly.

[0060] Specifically, the outer edge of the abutment portion 33 fits tightly against the inner edge of the partition rib 15 to prevent cement mortar from falling into the first water receiving groove 11 during construction. The vertical length of the abutment portion 33 can be less than the depth of the first water receiving groove 11 to facilitate the removal of the anti-grout cover 3.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
