Description

TECHNICAL FIELD

[0001] The patent application belongs to the technical field of assembled bathroom, and relates to an integrated bathroom basin water collecting and external drainage system and a construction method thereof. BACKGROUND

[0002] The traditional building method bathroom drainage is mainly divided into adopting different layers of drainage and adopting a caisson drainage. When the different layers of drainage are adopted, the drainage pipeline penetrates through the floor to the roof of the floor below, and is connected horizontally on the floor below, and then is connected to the main drainage vertical pipe. The upper floor and the lower floor are closely related and influence each other. When the caisson drainage is adopted, the floor is sunken, and occupies part of the space of the roof of the floor below (the roof space of the floor above is also partially occupied by the upper floor owner). During decoration, the drainage pipeline is connected in the caisson, then the caisson is filled and leveled to do waterproofing, and then the floor tiles are pasted, and the sanitary wares are installed to decorate the bathroom. The work load is increased, and the cost is high. The main disadvantage of the traditional building method bathroom is that a large amount of masonry site construction is used in the construction and decoration process, the process is complex, the construction period is long, the cost is high, and the quality guarantee is difficult.

[0003] In order to eliminate the disadvantages of the traditional building method bathroom, there are "whole bathroom", "whole bathroom", "integrated bathroom", "assembled bathroom" and other factory-produced parts on-site assembly bathroom products on the market. Then, like the traditional building method bathroom, the drainage pipeline is arranged under the basin. This must support the waterproof basin on the ground, and the bolt multi-point support scheme is generally used, so that the overall bottom basin structure height is high, not only the material consumption is large, but also the installation is troublesome. In addition, due to the suspended installation of the bottom basin during installation, the hollowing effect is obvious when stepping on the bathroom floor, and the vibration and impact generated during stepping directly affect the reliability of the drainage pipeline connector, and the use experience is obviously not as stable as the traditional building method bathroom.

DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, purposes and effects realized by the present patent application easy to understand, the following will make a specific description of the whole bathroom water collecting basin external drainage system and its construction method of the present patent application in combination with examples and drawings.

[0044] <Embodiment 1>

[0045] Figure 1 is the structure sectional view of the drainage collection system in the present patent application.

[0046] Figure 2 is the top view schematic diagram of the drainage collection system in the present patent application.

[0047] As Figure 1 and Figure 2As shown, the present embodiment provides a whole bathroom basin water collecting and draining system 100 for installing in a whole bathroom to collect and drain the sewage and waste water. At least including a main drainage vertical pipe 80, a drainage collector, a water collecting basin, a waste water pipe and a sewage pipe 61 leading to a toilet, the waste water pipe further contains a washing waste water pipe 62 leading to a washing table and a ground waste water pipe 63 leading to a ground side drainage port. In the present embodiment, the ground waste water pipe 63 receives waste water from the ground of the bathroom, including shower waste water, water collecting basin floor waste water, etc.; the washing basin in the bathroom adopts a rear drainage washing basin, the washing waste water pipe 62 is discharged to the drainage collector through the space outside the wall of the whole bathroom; the toilet in the bathroom adopts a rear drainage siphon type toilet, and its sewage pipe 61 is discharged to the drainage collector through the space outside the wall of the whole bathroom. The above ground waste water side drainage, rear drainage of the washing basin and the toilet eliminates the occupation of the horizontal drainage pipeline to the roof space, eliminates the sink, eliminates the mutual influence between the owners upstairs and downstairs, reduces the construction cost and decoration cost. In addition, although the toilet and the washing basin adopt rear drainage, the rear drainage pipeline will occupy some of the space between the wallboard of the whole bathroom and the building wall, but it occupies a small amount of space in the lower part of the wall, and the space in the upper part of the wall can be arranged as a niche for storage and storage space. If a new type of economical wall-mounted toilet, wall-mounted washing basin and niche wall are matched, a more reasonable whole bathroom will be achieved.

[0048] The main drainage vertical pipe 80 is generally installed in the building in advance when it is built, and passes through the floor 90 of the floor to drain the sewage and waste water in each bathroom on the floor. The drainage collector is installed on the main drainage vertical pipe 80 to collect and drain the sewage and waste water in the bathroom into the main drainage vertical pipe 80. The water collecting basin includes a bottom basin and a floor 30 laid in the floor laying area of the bottom basin. The bottom basin has a basin frame 10 and a bottom shell 20. The bottom shell 20 is vacuum formed on the outer periphery of the basin frame 10. The side surface of the basin frame 10 is provided with a drainage port 121. A side drainage connector 123 is installed outside the drainage port 121. One end of the side drainage connector 123 is communicated with the drainage port 121, and the other end is communicated with the ground waste water pipe 63, so that the drainage port 121 can be communicated with the ground waste water pipe 63. The water on the floor 30 flows into the ground waste water pipe 63 through the drainage port 121, and then flows into the drainage collector for drainage. In the present embodiment, the drainage collector is installed on one side of the basin frame 10 instead of the bottom, which greatly reduces the height of the bottom basin and avoids the floor from being installed in the air. The bottom of the bottom basin can be directly supported by the floor 90 or the installation platform, so that the platform construction has no difficulty and the cost is low. The construction and installation of the water collecting basin are also simple, the cost of the bathroom bottom plate is greatly reduced, and the structure of the water collecting basin is more stable.

[0049] Figure 3This is a schematic diagram of a partial pit box in this patent application.

[0050] In this embodiment, when installing the drain collector, a recess 91 needs to be dug at the floor level 90 corresponding to each bathroom on each floor. The drain collector is installed in the recess 91, and can be installed on the main drain riser 80 via a mounting connector 82. The main drain riser 80 has one and only one installation port 81 for installing the drain collector for each bathroom on each floor. For ease of construction, a small local pit box 92 can be configured, such as... Figure 3 As shown, the partial pit box 92 includes a recess 921 for installing a drain collector and a through hole 922 through which one end of the drain collector passes and is connected to the main drain riser 80. Figure 2 As shown, the partial pit box 92 is assembled onto the installation port 81, and the upper surface of the partial pit box 92 is aligned with the floor surface 90, thus completing the construction of the partial pit, greatly reducing construction difficulty and cost. Compared with the existing technology that connects sewage and wastewater separately to the main drainage riser, this embodiment only requires one installation port 81 to be opened on the main drainage riser for each bathroom on each floor. The structure is relatively simpler, the installation is more convenient and faster, and the manufacturing and installation costs are greatly reduced. In this embodiment, the installation port 81 is a standard DN110 water inlet (i.e., the diameter of the installation port 81 is 110mm), and the center of the installation port 81 is 75mm above the bottom surface of the pit 91. In addition, in practice, after the drainage collector is installed in the pit, the area above it can be used to install other commonly used bathroom facilities such as washbasins and mirror cabinets, making reasonable use of space.

[0051] Figure 4 This is a schematic diagram of the drainage collector in this patent application.

[0052] In this embodiment, as Figure 4 As shown, the drainage collector includes a main collection pipe 40 and a water seal component 50. The main collection pipe 40 has a pipe body 41, one end of which is provided with an outlet 42 for discharging sewage and wastewater. The outlet 42 leads to the installation port 81 of the main drainage riser 80. The other end of the pipe body 41 is provided with an inlet for collecting sewage and wastewater, which is further divided into a sewage inlet 43 for connecting to a sewage pipe 61 and a wastewater inlet 44 for connecting to a wastewater pipe. Figure 1 and Figure 4 As shown, a drainage slope 45 is provided inside the pipe body 41. The drainage surface 451 of the drainage slope 45 is inclined from the wastewater inlet 44 toward the outlet 42, forming a certain slope to facilitate the flow of water down. The slope is 5%-15%, preferably 10%.

[0053] like Figure 4As shown, the sewage inlet 43 is formed at the top of the pipe body 41, and the sewage inlet 43 is provided with a sewage inlet connector 71. The sewage inlet connector 71 in this embodiment is a 90-degree elbow connector, one end of which extends into the sewage inlet 43, and the other end is in a horizontal position for connecting the sewage pipe 61. The sewage in the sewage pipe 61 enters the inside of the pipe body 41 through the sewage inlet connector 71 and flows out of the outlet 42 into the main drainage vertical pipe 80. The end of the sewage inlet connector 71 extending into the sewage inlet 43 is provided with an arc-shaped flow guide surface 711, which can change the direction of the sewage flow and better guide the sewage to flow onto the drainage slope 45 in the pipe body 41 and then flow down along the drainage surface 451. The arc-shaped flow guide surface 711 can change the direction of the originally vertically falling water flow to a tangential direction along the arc-shaped flow guide surface 711, thereby reducing the noise of the water flow falling on the drainage slope 45. In this embodiment, the sewage inlet connector 71 can be integrally formed with the pipe body 41.

[0054] The wastewater inlet 44 is formed at the end of the pipe body 41 away from the outlet 42 and opposite to the outlet 42, and is provided with a wastewater inlet connector 72 (which can be integrally provided with the pipe body 41). The water seal component 50 is arranged beside the wastewater inlet 44. Wastewater flows from the wastewater inlet connector 72, flows through the water seal component 50, and then flows into the wastewater inlet 44. The wastewater inlet connector 72 has a first water inlet end 721, a second water inlet end 722, and a wastewater outlet end 723. The first water inlet end 721 is used to communicate with the washing wastewater pipe 62, the second water inlet end 722 is used to communicate with the ground wastewater pipe 63, and the wastewater outlet end 723 extends into the water seal component 50 and forms a gap 51 between the inner wall of the water seal component 50 for water flow. As shown, Figure 2 As shown, the wastewater inlet 44 has a lower edge 441, the top of which is flush with or lower than the upper end edge 52 of the water seal component 50. When the water flow flows from the wastewater outlet end 723 into the water seal component 50 and gradually rises to form a water seal 53 in the water seal component 50, if the water flow continues to rise and overflow the upper end edge 52, the water flow will overflow from the wastewater inlet 44 and flow onto the drainage slope 45. In this embodiment, the top of the end of the drainage slope 45 close to the wastewater inlet 44 is lower than the lower edge 441 or flush with the lower edge 441, facilitating the flow of wastewater from the wastewater inlet 44. The bottom of the drainage slope 45 is also provided with a support plate 452, which has a shape matching the lower edge 441, so that the drainage slope 45 can be directly inserted into the pipe body 41 and fit with the lower edge 441, making the structure of the drainage slope more stable. In addition, the water flow flowing from the wastewater outlet end 723 into the water seal component 50 can form a water seal of more than 50 mm as required by the national standard, which is not easy to dry out.

[0055] Figure 5is a top view sectional view of the drainage collector in the patent application.

[0056] Figure 6 is Figure 5 A view of

[0057] Figure 7 is Figure 5 B view of

[0058] As shown in Figure 4 and Figure 5 , the drainage slope 45 is also provided with a deflector 46 at one end close to the outlet 42, which can deflect the direction of water flow. The deflector 46 has a deflector body 461, a fixed bottom end and a fixed top end, the fixed bottom end is connected with the drainage slope, and the fixed top end has a shape matching the inner wall of the collection main pipe. The drainage slope 45 and the deflector 46 can be integrally formed and directly inserted into the inner wall of the collection main pipe for installation. Under the action of the deflector, the direction of the flowing water at the outlet is guided and changed by the deflector, and the flowing water can enter the main drainage vertical pipe at a certain angle (preferably the tangent direction of the main drainage vertical pipe wall) from the pipe wall of the main drainage vertical pipe. Under the joint action of the initial velocity and gravity, the flowing water can form a spiral falling along the inner wall of the main drainage vertical pipe, thereby greatly reducing the drainage noise.

[0059] As shown in Figure 5 , a reinforcing plate 47 is further arranged between the deflector body 461 and the inner wall of the pipe body 41. When the amount of sewage is large at one time, the deflector body 461 will be impacted, and the reinforcing plate 47 can support the deflector 461, strengthen the strength and stability of the structure, and avoid the deflector body 461 from being washed away or cracked by the water flow. In this embodiment, the deflector 46, the reinforcing plate 47 and the drainage slope 45 can be integrally arranged, and during installation, they can be directly inserted into the pipe body 41.

[0060] In this embodiment, the sewage pipe 61 and the washing and washing waste water pipe 62 are transparent steel wire flexible pipes, the ground waste water pipe 63 is a transparent elliptical flexible pipe, and the collection main pipe 40 and the water seal component 50 are also transparent plastic parts. By using transparent materials to manufacture these components, the working condition of the drainage pipeline can be visually inspected, and leakage and other faults can be easily found. At the same time, the ground waste water pipe 63 adopts a flat pipe with an elliptical cross section, which can reduce the loss of drainage drop, and the drainage pipes (i.e. the sewage pipe 61 and the washing and washing waste water pipe 62) from the drainage collector to the toilet and the washing basin adopt steel wire flexible pipes, which can be flexibly connected to reduce the risk of pipeline leakage.

[0061] Figure 8 is a structural schematic view of the water collecting basin in the patent application.

[0062] As shown in Figure 8As shown, the water collecting basin comprises a bottom basin and a floor 30 laid in the floor laying area within the bottom basin, wherein the bottom basin has a basin frame 10 and a bottom shell 20, and the bottom shell 20 is vacuum formed on the outer periphery of the basin frame 10. The side of the basin frame 10 is provided with a drainage port 121, which is at least lower than the height of the top surface of the floor 30 or flush with the top surface of the floor 30, so as to ensure that the water accumulated on the floor can be directly drained from the side of the basin frame 10 along the drainage port 121.

[0063] Figure 9 is a partial cross-sectional view of the floor in the patent application.

[0064] Figure 10 is a cross-sectional view of the water collecting basin in the patent application.

[0065] As shown in Figure 9 and Figure 10 , the floor 30 has three layers from bottom to top: a water slope pad layer 31, a tempered glass plate layer 32, and an anti-slip layer 33. The water slope pad layer 31 is at the bottom layer, and the tempered glass plate layer 32 is laid above the slope pad layer 31. Using tempered glass as the stiffness, strength, and flatness of the bathroom floor provides reliable guarantee and ensures the stability and firmness of the integrated water collecting basin, which is also cost-effective. However, the surface of tempered glass is relatively smooth, so the embodiment also has an anti-slip layer 33 attached above the tempered glass plate layer 32, and the anti-slip layer 33 is made of PVC anti-slip film. As shown in Figure 4 , the position of the anti-slip layer 33 is slightly higher than the lowest part of the drainage port 121, which facilitates water drainage. The water slope pad layer 31, the tempered glass plate layer 32, and the anti-slip layer 33 are all integrally designed through special glue to form a water collecting basin, and the water slope pad layer 31, the tempered glass plate layer 32, the anti-slip layer 33, and the laying glue are all made of hydrophobic materials to ensure the water collecting basin is hydrophobic, which is beneficial to keeping dry and clean.

[0066] In this embodiment, the material of the water slope pad layer 31 is XPS (extruded polystyrene foam), which has a unique micro-closed cell honeycomb structure, making it have the characteristics of high density, high compression performance, low thermal conductivity, low water absorption, and low water vapor permeability coefficient. Moreover, in a long-term high-humidity or immersion environment, the XPS board can still maintain its excellent thermal insulation performance, and it is a hydrophobic thermal insulation material, which is beneficial to keeping dry and clean. Therefore, a floor heating device can be laid in the water slope pad layer 31, and the floor heating device can be selected as an electric heating wire 34 or a hot water pipeline. By setting the floor heating device in the water slope pad layer 31 to form a waterproof electric floor heating, the experience of taking a shower in winter is comfortable, the seat ring electric heating device of the toilet seat can be saved, the warm air device of the whole bathroom can be saved, and the bathroom can be used for rapid dehumidification, even in cold and humid weather, the bathroom can be used as a clothes drying place with the cooperation of the ventilation fan, which has multiple uses and a wide range.

[0067] In the process of laying the floor, in order to facilitate the water to be smoothly discharged from the drain 121, the top surface of the water slope cushion layer 31 can be arranged to be inclined towards the drain, that is, the water slope cushion layer 31 has a certain slope, and in order to ensure that the user is not easy to fall on the ground during use, the slope should not be too large, and is preferably between 0.5% and 2%. In the current bathroom design standard such as GB50015 "Building Water Supply and Drainage Design Specification", it is stipulated that the "gutter slope should not be less than 0.3%" for rainwater discharge, and the general slope of the plastic drainage pipe is 1.2% for an outer diameter of 110 mm, 0.7% for an outer diameter of 160 mm, and 0.5% for an outer diameter of 315 mm. In the present embodiment, the super-high level of flatness provided by the tempered glass and the plastic surface anti-slip film material are comprehensively considered, and therefore the slope is preferably 1%.

[0068] In the present embodiment, the basin frame 10 adopts a profile splicing structure, which is convenient for production and assembly. The specific structure is as follows: as shown in Figure 8 The basin frame 10 includes a frame unit and a drainage unit 12 that are inserted into each other, and the frame unit and the drainage unit 12 are inserted into each other to enclose the floor laying area inside. The frame unit and the drainage unit 12 are respectively standard modular profile structures made of plastic or aluminum profiles. The splicing type not only has a simple structure, is easy to produce and has low cost, but also forms a standard modular structure of the splicing unit, which is convenient to install and has a wide application range. At least one drain 121 is further provided on the drainage unit 12 to facilitate the discharge of water accumulated on the floor. The drain 121 is arranged on the side of the entire basin frame 10, so that the accumulated water can flow directly from the side, without the need to lay a floor drain on the floor and lay a drainage pipe at the bottom of the floor as in the prior art, which greatly simplifies the structure and reduces the height of the basin.

[0069] As shown in Figure 8 The frame unit includes a plurality of basin frame strips 14 and a plurality of splicing corners 15. Specifically, the basin frame 10 provided in the present embodiment is a quadrilateral (i.e., the floor laying area enclosed has an outer contour of a quadrilateral), has a pair of first edges arranged in the length direction and a pair of second edges arranged in the width direction, and the first edges and the second edges are connected by the splicing corners 15. In the present embodiment, one of the pair of first edges and one of the pair of second edges are both basin frame strips 14, and the other second edge is a combination of a basin frame strip 14 and a drainage unit 12, that is, a drainage unit 12 is arranged between two basin frame strips 14.

[0070] Figure 11 is a structure diagram of the drainage unit in the present patent application.

[0071] Figure 12 is a structure diagram of the basin frame strip in the present patent application.

[0072] Figure 13 is a structural diagram of the splicing corner in this patent application.

[0073] As shown in Figure 11-13 , the basin frame strip 14 and the drainage unit 12 are both long strips, and their lengths can be set according to actual needs. The two side faces of the basin frame strip 14 are provided with splicing parts 141, the two side faces of the drainage unit 12 are provided with plug-in cooperation parts 122 that cooperate with the splicing parts 141, and the side of the splicing corner 15 facing the splicing part 141 is provided with a splicing cooperation part 151 (i.e. the two inner side faces adjacent to the splicing corner 15), which is used for splicing with the basin frame strip 14. In this embodiment, the splicing part 141 is a hole position as shown in Figure 12 , the shape of the hole position can be a square as shown in the figure, or a circle or other shapes, the plug-in cooperation part 122 and the splicing cooperation part 151 are protrusions as shown in Figure 11 and Figure 13 that can be inserted into the splicing part 141 (the shape of the protrusion can be a square as shown in the figure, or a circle or other shapes, and the protrusion can be a hollow structure as shown in the figure, or a solid structure). The basin frame strip 14, the splicing corner 15 and the drainage unit 12 are plug-in connected into one body to form the basin frame 10 by inserting the protrusions into the hole positions in the form of male and female plug-in. When plug-in, the connection strength and waterproof performance can be further improved by glue bonding. In the actual process, the splicing part 141 can also be a plug block protruding from the side face of the frame unit, and the plug-in cooperation part 122 and the splicing cooperation part 151 are plug holes opened in the side faces of the drainage unit 12 and the splicing corner 15, and the basin frame strip 14, the splicing corner 15 and the drainage unit 12 are plug-in connected into one body in the form of male and female plug-in by inserting the plug block into the plug hole.

[0074] Since the wall surface needs to be installed above the basin frame 10 when the assembled toilet is established, the limiting part 13 is arranged on the top of the frame unit and the drainage unit 12, which is used for limiting installation of the connecting piece of the wall surface of the assembled toilet (since the wall surface is usually made of glass plate, it needs to be installed through a connecting piece). Therefore, the limiting parts arranged above the basin frame strip 14, the splicing corner 15 and the drainage unit 12 can be spliced together, and the limiting parts all include the cladding limiting strip 131 and the embedded limiting strip 132. The cladding limiting strip 131 is located outside the embedded limiting strip 132, used for partially or completely cladding the outer side of the connecting piece, and the embedded limiting strip 132 is used for embedding into the bottom of the connecting piece. The height of the cladding limiting strip 131 is higher than that of the embedded limiting strip 132, so that the connecting piece can be firmly limited above the basin frame 10, the stability of the structure is enhanced, and displacement is avoided. When the connecting piece is actually installed, glue needs to be applied on the surface of the connecting piece at the connecting position of the cladding limiting strip 131 and the embedded limiting strip 132, which is used for fixing. In the embodiment, the cladding limiting strip 131 and the embedded limiting strip 132 arranged on the basin frame strip 14 and the drainage unit 12 are in the shape of a long strip, and the cladding limiting strip 131 and the embedded limiting strip 132 arranged on the splicing corner 15 are in the shape of L. When the basin frame strip 14, the splicing corner 15 and the drainage unit 12 are spliced together, the cladding limiting strip 131 and the embedded limiting strip 132 are also spliced together.

[0075] Figure 14 FIG. 9 is a structural schematic diagram of a 90-degree splicing corner in the patent application.

[0076] Figure 15 FIG. 10 is a structural schematic diagram of a 135-degree splicing corner in the patent application.

[0077] In the embodiment, as shown in FIG. 11, the main part of the splicing corner 15 is in the shape of a square block, used for splicing the basin frame strip 14 at the corner. In actuality, there may be irregular shapes of the ground of the bathroom, so the main part of the splicing corner 15 can also be in the shape of a 90-degree corner, a 135-degree corner or other angles, as shown in FIG. 12 or FIG. 13. Figure 13 Figure 13 Figure 14

[0078] The basin frame strip 14, the splicing corner 15 and the drainage unit 12 are all plastic or aluminum profile structures, which have the characteristics of standardization and modularization. When the basin frame 10 is connected, splicing and clamping can be adopted, and the installation is very simple and low in cost. At the same time, the length of the basin frame strip 14 determines the length of one side of the bathroom, so adjusting the length of the basin frame strip 14 can produce a basin with different plane sizes, which realizes customization of the basin at low cost and high efficiency.​​​

[0079] As Figure 10 shown, the bottom shell 20 is wrapped around the outer periphery of the basin frame 10, and the bottom shell 20 is made of PVC plate with a thickness of 1-5 mm, preferably 3 mm. PVC is a hydrophobic material, which ensures that the entire bottom basin is hydrophobic, conducive to keeping dry and sanitary; and the present embodiment uses vacuum forming, which does not require demolding operation, and has high production efficiency. During the vacuum forming process, the PVC plate is heated and softened, and is blown up to a stretched and thinned state, and is then moved into the basin frame. The blown-up PVC plate will cover the outer surface of the basin frame, and then a negative pressure is formed by vacuumizing inside the basin frame, so that the softened PVC plate is attached to the basin frame to form the bottom basin. The bottom basin is removed from the vacuum forming machine and laid flat, and the excess PVC plate is trimmed while hot, and then naturally cooled. Because the temperature of the PVC plate is higher than that of the basin frame, the shrinkage of the PVC plate is greater than that of the basin frame during natural cooling, so that the PVC plate is tightly wrapped around the basin frame from the outside, thereby providing waterproofing. In addition, the PVC plate layer is prone to stretching during transportation. If the PVC plate is too thin, it will be easily damaged, and if the PVC plate is too thick, it will be difficult to form by vacuum forming. Therefore, the present embodiment selects a moderate thickness of 3 mm for the PVC plate, and in actual implementation, the actual size of the bottom basin can be adjusted accordingly.

[0080] The construction method of the integrated bathroom water collecting basin and external drainage system has the following steps:

[0081] Step one: material preparation: select appropriate lengths of several basin frame strips and several jointing corners according to the actual size and contour shape of the bathroom reserved on the floor, and prepare related materials such as drainage units, drainage collectors, side drainage connectors, sewage pipes, floor waste pipes, washing waste pipes, water slope cushion layers, tempered glass plate layers, and anti-skid layers;

[0082] Step two: basin frame splicing: the several basin frame strips, several jointing corners, and drainage units prepared in step one are spliced end to end to form the basin frame of the water collecting basin, and the interior of the basin frame is surrounded by a floor laying area;

[0083] Step three: vacuum forming: the basin frame formed in step two is wrapped with a PVC bottom shell on its outer periphery using a vacuum forming process to form a bottom basin;

[0084] Step four: sequentially lay a water slope cushion layer, a tempered glass plate layer, and an anti-skid layer in the floor laying area inside the bottom basin to form a water collecting basin;

[0085] Step five: digging and leveling and installation: a pit is dug on the floor near the main drainage vertical pipe, the size of the pit is 30cm long, 12cm wide and 4.5cm deep, the drainage collector is installed in the pit, the end of the outlet of the collection main pipe of the drainage collector is installed on the installation port of the main drainage vertical pipe, and the water collecting basin is installed on the floor on one side of the pit;

[0086] Or build an installation platform and install: the drainage collector is directly installed on the floor near the main drainage vertical pipe, and an installation platform with a height of 5cm is built on the floor of the whole bathroom on one side of the drainage collector, and the water collecting basin is installed on the installation platform;

[0087] Step six: installation of drainage joint: a side drainage joint is installed outside the drainage unit corresponding to the drainage port of the drainage unit;

[0088] Step seven: pipe laying: install the sewage pipe between the toilet outlet and the sewage inlet of the drainage collector, install the ground waste pipe between the side drainage joint and the waste water inlet of the drainage collector, and install the washing waste water pipe between the wash basin outlet pipe and the waste water inlet of the drainage collector, complete the installation of the water collecting basin drainage system of the whole bathroom;

[0089] In the above steps one to four, the process is completed in the factory to realize factory production. In step one, the material of the water slope cushion layer is XPS, and the water slope cushion layer is pre-installed with a floor heating device and a temperature sensor, and the anti-skid layer is a PVC anti-skid film; in step four, when the water slope cushion layer is laid, the top surface of the water slope cushion layer is inclined to form a slope towards the drainage port, the slope is 0.5%-2%, preferably 1%, and the bottom shell, the basin frame, the water slope cushion layer, the tempered glass plate layer and the anti-skid layer are bonded by glue.
