Description

Technical Field

[0001] The present invention relates to a floor drain installation system, in particular to a floor drain installation system with an ultra-thin cover plate, comprising a combined floor drain and sandstone concrete, a waterproof layer and a tile layer distributed from bottom to top, and is installed in a toilet or bathroom in a pre-buried manner. Background Art

[0002] Bathrooms are usually equipped with floor drains to collect bath water and connect it to a sewer pipe below the ground.

[0003] For example, the combined floor drain with water seal, odor prevention and fast large flow discharge with the authorization announcement number CN210151894U includes a base, a bowl-shaped sealing cover, a discharge plate and a spring-loaded device; the spring-loaded device is installed in the spring-loaded device mounting hole of the base and is tightened and fixed, and the bowl-shaped sealing cover and the discharge plate are installed on the top surface of the spring-loaded device from bottom to top by screws, forming a combined floor drain as a whole.

[0004] Another example is a combined floor drain structure with the authorization announcement number CN217267948U, which includes a water collecting seat, a water collecting pan, and a floor drain core. The water collecting seat is provided with a first water trough and threaded holes for installing the floor drain core from top to bottom. A corner block for supporting the water collecting pan is fixed in the first water trough. The corner block limits the water collecting pan to the center position of the first water trough so that there is a distance between the water collecting pan and the trough wall of the first water trough. The top surface of the water collecting pan is not higher than the top surface of the water collecting seat. A second water trough is provided on the water collecting pan, and drainage holes are provided on the side walls of the water collecting pan. The floor drain core is covered with a filter element.

[0005] The drainage floor drain with authorization announcement number CN208251281U includes a water storage box, a water collection tank and a drainage pipe. The water storage box is connected to the water collection tank, and the water storage box is connected to the drainage pipe. A water seal assembly is provided in the water storage box.

[0006] A cover is typically placed above the drain sump. This prevents debris like hair from entering and potentially clogging the drain, while also making it easier to open and clean the drain. Therefore, when constructing a bathroom floor, the relative heights of the sump, cover, and tiles are often crucial. Ideally, the cover should be flush with the top surface of the tiles.

[0007] Commonly used ceramic tiles and their thicknesses include 5mm mosaic tiles, 10mm vitrified tiles, and 25mm marble. Due to the different thicknesses of different ceramic tiles, the cover plate may exceed or fall short of the surface of the tiles after installation, which not only creates difficulties in the installation and construction of the floor and floor drain, but also after the floor drain is installed, there may be problems such as water not being smoothly introduced into the sewer through the floor drain, hair and other debris not being effectively blocked, or the floor drain and the floor being uneven and unsightly. Summary of the Invention

[0008] Based on the above-mentioned problem that the floor drain cover is unevenly installed due to the different thickness of tiles, which causes difficulties in the installation and construction of the floor and the floor drain, the present invention provides a floor drain installation system and installation method with an ultra-thin cover, by arranging the water collecting plate of the water collecting part above the accommodating frame, the water collecting frame of the water collecting part is height-adjustably arranged in the accommodating frame, the water seal and the drainage part are arranged below the waterproof layer, the upper edge plate is flush with the waterproof layer, and the water collecting plate is flush with the upper surface of the tile layer, thereby realizing the adjustment of the installation height of the water collecting plate relative to the accommodating frame according to the different thickness of the tile layer, minimizing the residual leakage water between the tile layer and the waterproof layer, and improving the sealing and aesthetics of the floor drain.

[0009] The technical solution adopted by the present invention to solve the above technical problems is: an ultra-thin cover plate floor drain installation system, comprising an ultra-thin cover plate combined floor drain and sandstone concrete, a waterproof layer and a tile layer distributed from bottom to top;

[0010] The combined floor drain with an ultra-thin cover plate comprises a water collecting portion, a drainage portion and a water sealing member;

[0011] The water collecting portion includes a water collecting plate and a water collecting frame provided in the middle of the water collecting plate; the water collecting plate includes two inclined surfaces with a lower centerline position and a higher side position; the water collecting frame includes a peripheral side wall and a water outlet at the bottom;

[0012] The drainage part includes a concave receiving frame and a downpipe; the receiving frame is provided with an upper edge plate around it, and the bottom of the receiving frame is provided with a water outlet hole connected to the downpipe;

[0013] The water collecting plate of the water collecting part is arranged above the accommodating frame, and the water collecting frame of the water collecting part is arranged in the accommodating frame in an adjustable manner; the water outlet is opposite to the water outlet;

[0014] The water seal comprises a curved tube body, one end of which is provided with a transverse water outlet, and the other end of which is provided with an upwardly opening interface, the interface being rotatably connected to the lower end opening of the sewer pipe;

[0015] The water seal and drainage part are located below the waterproof layer, the upper edge plate is flush with the waterproof layer, and the water collecting plate of the water collecting part is flush with the upper surface of the tile layer; the position of the horizontal water outlet of the water seal is lower than the water outlet hole of the drainage part.

[0016] The preferred technical solution adopted by the present invention to solve the above technical problem is: pads are respectively provided on two opposite sides of the water collecting frame;

[0017] The pad includes a base and a connecting portion above the base, wherein the connecting portion is provided with a plurality of gear teeth distributed along the height direction;

[0018] A plurality of gear slots for inserting the gear spigots are correspondingly distributed along the height direction on the peripheral side walls of the two opposite sides of the water collecting frame;

[0019] The gear inserts are inserted into the gear slots of different heights, and the base of the pad is placed at the bottom of the accommodating frame, so that the water collecting frame can be adjusted in height in the accommodating frame.

[0020] The preferred technical solution adopted by the present invention to solve the above technical problems is: a cover plate is provided at the opening of the water collecting frame, and a plurality of filter holes are distributed on the surface of the cover plate;

[0021] The cover plate includes two inclined surfaces with a lower centerline position and a higher side position.

[0022] The preferred technical solution adopted by the present invention to solve the above technical problem is: the cover plate is a part of the water collecting plate;

[0023] The two inclined surfaces of the cover plate, whose center line is low and whose side positions are high, are part of the two inclined surfaces of the water collecting plate, whose center line is low and whose side positions are high.

[0024] The preferred technical solution adopted by the present invention to solve the above technical problem is: the filter holes are V-shaped narrow holes distributed in parallel along the length direction of the cover plate.

[0025] The preferred technical solution adopted by the present invention to solve the above technical problem is: the width of the water collecting plate is smaller than the width of the opening of the accommodating frame.

[0026] The preferred technical solution adopted by the present invention to solve the above technical problems is as follows: the curved tube body of the water seal comprises a first curved portion close to the interface and a second curved portion close to the horizontal water outlet, and an inclined portion connecting the first curved portion and the second curved portion;

[0027] The inclined portion is inclined upward from the first curved portion to the second curved portion and from low to high; the lower end surface of the second curved portion is higher than the upper end surface of the first curved portion;

[0028] When the water level in the water seal is higher than the upper end surface of the first curved portion and lower than the lower end surface of the second curved portion, a floor drain water seal can be formed.

[0029] The preferred technical solution adopted by the present invention to solve the above technical problem is that the interface of the water seal and the lower end opening of the downpipe of the drainage part are rotatably connected through 360 degrees.

[0030] The preferred technical solution adopted by the present invention to solve the above technical problems is: the interface is a threaded interface, which is threadedly connected to the lower end opening of the sewer pipe.

[0031] Another technical solution adopted by the present invention to solve the above technical problems is: a method for installing a floor drain with an ultra-thin cover plate, comprising the following installation steps:

[0032] Step 1: Connect the horizontal water outlet at one end of the curved tube body of the water seal to the sewer, and place the interface opening at the other end of the curved tube body upward in the reserved installation position of the water collection part of the combined floor drain of the ultra-thin cover plate;

[0033] Step 2: Cut the lower end of the drain pipe to make the overall height of the drain adapt to the reserved installation position, rotatably connect the lower end opening of the drain pipe to the interface of the water seal, and rotate to adjust the accommodating frame of the drain to a suitable position and direction;

[0034] Step 3: While ensuring that the horizontal water outlet of the water seal is lower than the water outlet hole of the drainage part, fill the surrounding areas of the water seal and the drainage part with sand and gravel concrete until the height approaches the height of the upper edge plate of the drainage part;

[0035] Step 4: Apply a waterproof layer on the sand and gravel concrete, and extend the waterproof layer to the upper surface of the upper edge plate so that the upper edge plate is flush with the waterproof layer, and let it stand to complete the waterproof test;

[0036] Step 5: Laying a tile layer on top of the waterproof layer and reserving a location for installing the water collection part at the opening of the receiving frame;

[0037] Step 6: Cut the water collecting plate of the water collecting part to match the reserved installation position, insert the gear teeth of the two pads into the appropriate gear slots of the water collecting frame of the water collecting part, and place the water collecting frame into the accommodating frame. The base of the pad is placed at the bottom of the accommodating frame so that the water collecting plate of the water collecting part is flush with the upper surface of the tile layer; the water outlet of the water collecting part is opposite to the water outlet of the accommodating frame;

[0038] Step 7: Complete the sealing and filling between the water collecting plate and the tile layer.

[0039] Compared with the prior art, the advantages of the present invention are: 1. A water collecting frame is provided in the middle of the water collecting plate, and a recessed containing frame is provided in the drainage part. The water collecting frame is arranged in the containing frame. When water flows through the collection and diversion of the water collecting plate, it first enters the water collecting frame, and then enters the containing frame from the water collecting frame, and then is discharged from the sewer pipe. In the process of drainage of the floor drain, the water flow is always guided, especially from the water collecting frame into the containing frame, thereby avoiding the water flow with a higher flow rate leaking from the opening of the containing frame and entering between the waterproof layer and the tile layer.

[0040] 2. The height of the water collecting frame is adjustable in the accommodating frame. Therefore, even if the drainage part and the water seal have been installed and the height of the drainage part has been fixed by the sand and gravel concrete, after the tile layer is laid, the height of the water collecting plate can still be adjusted according to the thickness of the tiles used to be flush with the upper surface of the tiles. This solves the problem that it is difficult to adjust the height of the floor drain cover after the tile layer is laid during the construction and installation of the ground and floor drain, resulting in great construction difficulty, high requirements on the skills of the masons, and unsightly installation of the floor drain. It ensures that the water flows smoothly into the drainage part through the guidance of the water collecting plate, while ensuring the flatness and beauty of the ground.

[0041] 3. After years of use, the sealants between the tiles, between the tiles and the wall, and between the tiles and the water collection plate of the floor drain will age and crack, causing leakage. Since the water seal and drainage part are located below the waterproof layer and the upper edge plate is flush with the waterproof layer, the leaked water will eventually flow along the waterproof layer into the containing frame and then discharged into the sewer, avoiding the leaked water from accumulating between the tile layer and the waterproof layer for a long time, forming moisture or causing mold.

Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0058] As Figure 1 and Figure 2 shown is the floor drain installation system 200 of the ultra-thin cover plate provided by the present application, which comprises a combined floor drain 100 of the ultra-thin cover plate and a sand and gravel concrete 201, a waterproof layer 202 and a ceramic tile layer 203 distributed from bottom to top.

[0059] Among them, as Figure 3 and Figure 4 As shown, the combined floor drain 100 with an ultra-thin cover plate includes a water collection portion 10, a drainage portion 20, and a water seal 30. The water collection portion 10 comprises a water collection plate 11 and a water collection frame 12 disposed in the middle of the water collection plate 11. The water collection plate 11 includes two inclined surfaces 11s, one at the center and one at the sides. The water collection frame 12 includes sidewalls 13 and a drain outlet 14 at the bottom.

[0060] The drainage part 20 includes a recessed receiving frame 21 and a downpipe 22. The receiving frame 21 is provided with an upper edge plate 23 around it, and a water outlet 24 is provided at the bottom thereof, and is connected to the downpipe 22. Figure 8 As shown, the water collecting plate 11 of the water collecting part 10 is arranged above the accommodating frame 21, and the water collecting frame 12 of the water collecting part 10 is arranged in the accommodating frame 21 with adjustable height, and the water outlet 14 of the water collecting frame 12 is opposite to the water outlet 24 of the accommodating frame 21.

[0061] The water seal 30 includes a curved tube body 31 , one end of which is provided with a horizontal water outlet 32 ​​, and the other end of which is provided with an upwardly opening interface 33 , which is rotatably connected to the lower end opening of the downpipe 22 .

[0062] like Figure 1 and Figure 2 As shown, after the floor drain installation system 200 with an ultra-thin cover plate provided in this embodiment is installed, the water seal 30 and the drainage part 20 are located below the waterproof layer 202, the upper edge plate 23 is flush with the waterproof layer 101, the water collecting plate 11 of the water collecting part 10 is flush with the upper surface of the tile layer 203, and the position of the horizontal water outlet 32 ​​of the water seal 30 is lower than the water outlet hole 24 of the drainage part 20.

[0063] Thus, if Figure 10 and Figure 11 As shown, water on the floor of the toilet or bathroom first flows into the water collecting plate 11 along the upper surface of the tile layer 203, flows into the water collecting frame 12 along the two inclined surfaces 11s with a low centerline position and a high side position, enters the accommodating frame 21 of the drainage part 20 from the drain port 14 of the water collecting frame 12, and then enters the sewer pipe 22 from the water outlet 24 of the accommodating frame 21, and then enters the curved pipe body 31 of the water seal 30 and is discharged from the sewer.

[0064] The design of the ultra-thin cover plate floor drain installation system 200 has the following three advantages:

[0065] First, a water collecting frame 12 is provided in the middle of the water collecting plate 11, and a recessed receiving frame 21 is provided in the drainage part 20. The water collecting frame 12 is provided in the receiving frame 21. When water flows through the collection and diversion of the water collecting plate 11, it first enters the water collecting frame 12, and then enters the receiving frame 21 from the water collecting frame 12, and is then discharged from the sewer pipe 22. In this way, during the drainage process of the floor drain, the water flow is always guided, especially from the water collecting frame 12 into the receiving frame 21, thereby preventing water with a higher flow rate from leaking out from the opening of the receiving frame 21 and entering between the waterproof layer 202 and the tile layer 203.

[0066] Secondly, the height of the water collecting frame 12 is adjustable in the accommodating frame 21. Therefore, even if the drainage part 20 and the water seal 30 have been installed and the height of the drainage part 20 has been fixed by the gravel concrete 201, after the tile layer 203 is laid, the height of the water collecting plate 11 can still be adjusted according to the thickness of the tiles used to be flush with the upper surface of the tiles. This solves the problem that it is difficult to adjust the height of the floor drain cover after the tile layer 203 is laid during the construction and installation of the ground and floor drain, resulting in great construction difficulty, high requirements on the skills of the masons, and unsightly installation of the floor drain. This ensures that the water flows smoothly into the drainage part 20 under the guidance of the water collecting plate 11, while ensuring the flatness and beauty of the ground.

[0067] Again, after years of use, the sealant between the tiles, between the tiles and the wall, and between the tiles and the water collecting plate 11 of the floor drain will age and crack, causing leakage. Since the water seal 30 and the drainage part 20 are located below the waterproof layer 202, the upper edge plate 23 is flush with the waterproof layer 202, so the leaked water will eventually flow into the accommodating frame 21 along the waterproof layer 202 and then be discharged into the sewer, avoiding the leaked water from accumulating between the tile layer 203 and the waterproof layer 202 for a long time, forming moisture or causing mold.

[0068] like Figures 5 to 7 As shown, in this embodiment, the water collecting frame 12 is height-adjustable relative to the accommodating frame 21 by means of pads 40 provided on two opposite sides thereof. Specifically, the pad 40 includes a base 41 and a connecting portion 42 above the base 41. The connecting portion 42 is provided with a plurality of gear teeth d1 distributed along the height direction. A plurality of gear slots d2 for inserting the gear teeth d1 are correspondingly distributed along the height direction on the circumferential side walls 13 on two opposite sides of the water collecting frame 12. After the tile layer 203 is laid, the gear teeth d1 are inserted into the gear slots d2 of an appropriate height according to the height difference between the waterproof layer 202 and the tile layer 203, and then the base 41 of the pad 40 is placed at the bottom of the accommodating frame 21, so that the water collecting plate 11 is flush with the upper surface of the tile layer 203.

[0069] Combine Figure 1 、 Figure 2 and Figure 9From the perspective of the present invention, when the floor of a toilet or bathroom is being laid, the installation method of the floor drain installation system of the ultra-thin cover plate provided in this embodiment is used to carry out the construction and installation of the floor drain installation system 200 of the ultra-thin cover plate, as follows:

[0070] Step 1: Connect the horizontal water outlet 32 ​​at one end of the curved tube 31 of the water seal 30 to the sewer of the toilet or bathroom, and place the interface 33 at the other end of the curved tube 31 with the opening facing upwards in the reserved installation position of the water collection part 10 of the combined floor drain 100 with an ultra-thin cover plate;

[0071] Step 2: Cut the lower end of the drain pipe 22 of the drain section 20 so that the overall height of the drain section 20 is consistent with the reserved installation position, so as to prevent the entire floor drain from excessively protruding from the tile layer 203. Then, rotatably connect the lower end opening of the drain pipe 22 of the drain section 20 to the interface 33 of the water seal 30, and rotate it to adjust the receiving frame 21 of the drain section 20 to the appropriate position and direction.

[0072] Step 3: While ensuring that the horizontal water outlet 32 ​​of the water seal 30 is lower than the water outlet 24 of the drain portion 20, fill the surrounding area of ​​the water seal 30 and the drain portion 20 with gravel concrete 201 until it reaches the height of the upper edge plate 23 of the drain portion 20.

[0073] Step 4: Apply a waterproof layer 202 on the gravel concrete 201. Apply the waterproof layer 202 to the upper surface of the upper edge plate 23 so that the upper edge plate 23 is flush with the waterproof layer 202. Let it stand and complete the waterproof test.

[0074] Step 5: Lay the tile layer 203 on the waterproof layer 202 and reserve a location for the water collection unit 10 at the opening of the receiving frame 21;

[0075] Step 6: Cut the water collecting plate 11 of the water collecting part 10 to match the reserved installation position. At this time, since the water collecting plate 11 of the combined floor drain 100 with an ultra-thin cover plate can be easily and conveniently cut to change the length, it can be adapted to the size of the floor drain installation position of different toilets or bathrooms, thereby meeting various floor drain installation and use scenarios;

[0076] Insert the gear teeth d1 of the two spacers 40 into the appropriate gear slots d2 of the water collecting frame 12 of the water collecting part 10, and place the water collecting frame 12 into the accommodating frame 21. Place the base 41 of the spacers 40 at the bottom of the accommodating frame 21 so that the water collecting plate 11 of the water collecting part 10 is flush with the upper surface of the tile layer 203, and the drain port 14 is opposite to the water outlet hole 24 of the accommodating frame 21.

[0077] Step 7: Complete the sealing and filling between the water collecting plate 11 and the tile layer 203 .

[0078] It should be noted that, in other embodiments, the pad 40 may also have only one gear tooth d1, which is inserted into the gear slots d2 of different heights to achieve height adjustment; or the matching structure of the gear slot may not be provided, and the height adjustment may be achieved with pads of different sizes; of course, other methods may also be used to achieve height adjustment between the water collecting frame 12 and the accommodating frame 21, typically, flat-head screws are provided on two opposite sides of the water collecting frame 12, and its height is adjusted by screwing the screws, so that the height of the water collecting plate 11 is flush with the upper surface of the tile.

[0079] The structure of the spacer 40 with the plurality of gear teeth d1 provided in this embodiment cooperates with the plurality of gear slots d2 on the peripheral side walls 13 on two opposite sides of the water collecting frame 12, which has at least the following three advantages:

[0080] First, the height adjustment is achieved by inserting the gear insert d1 into the gear slot d2, which is more convenient and quick to operate without the use of auxiliary tools such as screwdrivers. Especially in muddy water construction work, workers usually rarely use tools such as screwdrivers, and can adjust the height of the water collecting frame 11 by hand;

[0081] Second, the engagement structure between the multiple gear teeth d1 and the gear slots d2 is more secure in the transverse direction, preventing the pad 40 from loosening from the water collection frame 12 and providing greater stability in the longitudinal direction, thereby preventing the water collection portion 10 from settling due to long-term use of the floor drain or users stepping on it, and preventing cracking and leakage in the sealing structure between the water collection plate 11 and the tile layer 203;

[0082] Third, compared with other height adjustment methods, the structure of the pad 40 with several gear teeth d1 and several gear slots d2 on both sides of the water collecting frame 12 is used to realize the production and processing of the components of the floor drain on a standardized assembly line, without the need to add additional production equipment for the production of pads 40 of different sizes, thereby saving manufacturing costs.

[0083] like Figure 1 and Figure 3 As shown, the curved tube body 31 of the water seal 30 includes a first curved portion 34a near the interface 33, a second curved portion 34b near the lateral water outlet 32, and an inclined portion 34 connecting the first curved portion 34a and the second curved portion 34b. The inclined portion 34 slopes upward from the first curved portion 34a to the second curved portion 34b, with the lower end surface of the second curved portion 34b being higher than the upper end surface of the first curved portion 34a.

[0084] Thus, if Figure 1 As shown, when the water level in the water seal 30 is higher than the upper end surface of the first bend 34a and lower than the lower end surface of the second bend 34b, a floor drain water seal can be formed to prevent odor and reptiles in the sewer from entering the toilet or bathroom through the floor drain.

[0085] Furthermore, the interface 33 of the water seal 30 is rotatably connected to the lower opening of the downspout 22 of the drain section 20 through 360°. This connection structure is designed primarily to accommodate toilets or bathrooms of varying architectural structures, where the relative orientations of the sewer and the reserved floor drain installation locations may vary widely. The 360° rotatable connection can accommodate the different installation positions of the water collecting plate 11 and the different installation angles of the drain section 20. During construction, even if the installation direction of the curved tube 31 of the water seal 30 is limited by the location of the sewer, the angle of the drain section 20 frame 21 can still be adjusted by rotating the downspout 22 through 360°, allowing the water collecting plate 11 to be installed at any suitable angle.

[0086] Furthermore, if Figure 3 As shown, the interface 33 is a threaded interface, which is threadedly connected to the lower end opening of the sewer pipe 22, so that the sealing between the two is better, and water is not easy to leak out from the interface 33, ensuring the dryness of the sand and gravel concrete 201.

[0087] like Figures 3 to 5 、 Figure 8 As shown, a cover plate 15 is provided at the opening of the water collection frame 12. The surface of the cover plate 15 is provided with a plurality of filter holes h, which are V-shaped slits distributed parallel to the length of the cover plate 15. The advantages of this structure are: first, it effectively prevents debris such as hair from entering the drain pipe 22 and causing blockage of the floor drain itself or even the sewer; second, the V-shaped slits have a diversion effect on the water flow, facilitating smooth drainage; and third, the V-shaped slits have a reverse blocking effect, preventing contaminated gases in the sewer from flowing back into the toilet or bathroom through the floor drain and causing environmental pollution.

[0088] Furthermore, if Figure 4 and Figure 5 As shown, the cover plate 15 is part of the water collecting plate 11 and also includes two inclined surfaces 15s with a low centerline position and a high side position. The two inclined surfaces 15s are part of the two inclined surfaces 11s of the water collecting plate 11. The advantages of this structural design are: first, the water collecting plate 11 is flat and beautiful as a whole, and the cover plate 15 and the water collecting plate 11 are well integrated and not easily flipped up; second, after the water flow is concentrated by the two inclined surfaces 11s of the water collecting plate 11, it flows smoothly along the centerline to the continuous centerline of the cover plate 15, making the drainage smoother; third, not only can the cover plate 15 be die-cast at the same time when the water collecting plate 11 is produced, but there is no need to add a separate cover plate installation step when installing the floor drain.

[0089] Furthermore, if Figure 4 and Figure 8As shown, the width of the water collecting plate 11 is smaller than the width of the opening of the accommodating frame 21. On the one hand, the portion of the floor drain exposed from the tile layer 203 is smaller, and the visual aesthetics is better. On the other hand, it can ensure that water flows through the water collecting plate 11 and then flows into the accommodating frame 21 and then enters the sewer pipe 22, preventing water from leaking between the tile layer 203 and the waterproof layer 202, which will cause the tiles and sealant to mold over time.
