Description

Technical Field

[0001] The invention relates to the technical field of drainage facilities, and in particular to a bathroom visible or concealed floor drain drainage facility and a construction process. Background Art

[0002] The bathroom floor drain is a device used for drainage, usually installed on the bathroom floor. Its main function is to collect and discharge water to prevent water from soaking the floor or walls, thereby keeping the room dry.

[0003] In the prior art, a Chinese patent document "Bathroom Floor Drain Assembly and Installation Method" with publication number CN110805114B proposes a bathroom floor drain assembly and installation method, in which a groove is provided on a waterproof bottom box, which extends along the width direction to the first end of the bottom box peripheral edge, and extends along the length direction toward two side surfaces on the bottom box peripheral edge adjacent to the first end, and the floor drain is embedded in the groove. The shape of the floor drain is adapted to the groove, so the bathroom floor drain assembly provided by the present invention has a large water storage capacity. By adopting the bathroom floor drain assembly and installation method provided by the present invention, when the water flow on the waterproof bottom box is large, the large flow of water can be quickly reduced when passing through the bathroom floor drain assembly, and then discharged into the ground sewer pipe through the first drainage hole, thereby improving the drainage efficiency of the bathroom floor drain assembly. However, consistent with the traditional method, the traditional floor drain usually only has a single drainage function and cannot simultaneously handle large flows of sewage and seepage and fine water accumulation on the ground. This leads to low drainage efficiency during peak periods of bathroom use or when encountering leakage, which easily causes water accumulation, thereby affecting the sanitary conditions and comfort of use of the bathroom. In addition, the traditional floor drain usually only performs rough filtering through a simple grille, and cannot effectively prevent large particles of impurities in sewage from entering the sewer pipe. This defect easily leads to pipe blockage, increases the frequency of maintenance and cleaning, and may also cause sewage backflow, further affecting the user experience of the bathroom. Therefore, the present application discloses a bathroom light and dark floor drain drainage facility and construction process to meet the requirements of smooth drainage of the bathroom.

[0012] Beneficial effects of the present invention: 1. The toilet open and hidden floor drain drainage facilities and construction technology are provided with a filter module and a lifting column for use. When the filter holes of the filter plate are blocked, the sewage gradually accumulates in the water collecting bucket, and the water level gradually rises. In the process of gradually rising, the sewage enters the retention box from the through hole at the bottom of the retention box. In the process of rising water level, the first floating plate is gradually pushed up, and the connecting column drives the movable plate and the lifting column to lift up. The lifting column penetrates the filter hole to push out the blocked filter residue, thereby cleaning the filter hole. After the lifting column pushes out the filter residue, the water flow will fall through the side screen and will not affect the flow of water. When the water level drops, the floating plate gradually resets and returns to its initial state to prepare for the next cleaning cycle. By setting the retention box and the first floating plate, automatic cleaning of the filter module is achieved. When the filter plate is blocked, the rising water level will automatically push the movable plate to push out the blockage from the filter hole, thereby ensuring the smooth flow of the drainage system and reducing the maintenance frequency.

[0013] 2. This kind of bathroom visible and hidden floor drain drainage facilities and construction technology are equipped with a self-cleaning module. When water flows through the water collecting bucket, under normal circumstances, a part of the water will flow into the cleaning box through the water inlet hole on one side of the water collecting bucket. As the water level rises, the second floating plate rises until the pushing block contacts the positioning block of the blocking block, pushing the blocking block upward, opening the water outlet, and the water stored in the cleaning box is flushed out through the water outlet with a certain pressure, forming an interval cleaning state, reducing blockage under normal use. Water flows through the filter tank and the drainage port to bring the filter residue out of the system to avoid secondary blockage. During the rising process, the blocking block drives the opening and closing plate to open upward synchronously through the connecting plate to open the drainage port. Under normal conditions, the drainage port is in a closed state and will only be opened synchronously during the interval flushing process. When the drain is blocked, the water accumulates, and during the rising process of the water level, it will also cooperate with the lifting column to clean the filter residue that is pushed out.

[0019] like Figures 1 to 9As shown, the bathroom visible and hidden floor drain drainage facility comprises: a bathroom floor 1, a main drain pipe 31 is arranged below one side of the bathroom floor 1, a first water outlet pipe 2 and a second water outlet pipe 30 are respectively arranged on one side of the bathroom floor 1 close to the main drain pipe 31, an visible floor drain 3 is arranged on the top of the first water outlet pipe 2, a hidden floor drain body 32 is arranged above the second water outlet pipe 30, water storage pipes 33 are arranged below the first water outlet pipe 2 and the second water outlet pipe 30, and the first water outlet pipe 2 and the second water outlet pipe 30 are both connected to the main drain pipe 31; a filter assembly, the filter assembly is arranged inside the visible floor drain 3, the filter assembly comprises a filter module and a self-cleaning module, the filter module is used for The self-cleaning module is used to filter the domestic sewage in the toilet, and the self-cleaning module is used to clean the filter module; wherein the toilet floor 1 is provided with a cushion layer 34, a waterproof layer 35, a mortar layer 36 and a floor tile 37 from bottom to top, and the cushion layer 34, the waterproof layer 35, the mortar layer 36 and the floor tile 37 are all arranged with a gentle slope of 5%, the hidden floor drain body 32 is arranged inside the mortar layer 36, and a filter residue box 39 is also arranged on one side of the mortar layer 36, the top of the visible floor drain 3 and the filter residue box 39 are both flush with the top surface of the floor tile 37, and the outer surfaces of the hidden floor drain body 32 and the filter residue box 39 are both provided with a plurality of seepage holes, and the outer surfaces of the hidden floor drain body 32 and the filter residue box 39 are both wrapped with geotextiles; During the construction process, first, the position of the main drain pipe 31 must be accurately located on the bathroom floor 1, and the interfaces of the first outlet pipe 2 and the second outlet pipe 30 must be reserved to ensure that the position and slope of each outlet pipe meet the design requirements. Then, the visible floor drain 3 and the hidden floor drain body 32 must be installed to ensure that the hidden floor drain body is buried in the mortar layer 36. The visible floor drain 3 is connected to the first outlet pipe 2. A filter assembly, including a filter module and a self-cleaning module, is installed inside the visible floor drain 3 to ensure smooth water flow. Then, in the bathroom, The cushion layer 34, waterproof layer 35, mortar layer 36 and floor tiles 37 are laid on the bathroom floor 1 in sequence, ensuring that the gentle slope design between the layers of materials reaches the 5% slope requirement, thereby guiding the water to flow naturally to the floor drain. After the outer surface of the hidden floor drain body 32 and the filter box 39 is wrapped with geotextile, it is integrated with the mortar layer 36 to ensure the concealment and anti-seepage effect of the drainage system. Finally, the top of the exposed floor drain 3 and the filter box 39 is adjusted to be flush with the floor tiles 37, the construction is completed, and a drainage test is carried out to ensure The entire drainage system is leak-free and blockage-free, and the drainage speed and effect meet the design standards. If poor drainage or leakage occurs, it should be adjusted and repaired in time to ensure the construction quality. The two drainage methods of open floor drain 3 and hidden floor drain are set to ensure the efficient drainage capacity of the bathroom. The open floor drain 3 is used for rapid drainage, and the hidden floor drain is responsible for the seepage discharge in the hidden area to prevent water accumulation. Secondly, the introduction of the filter component filters the domestic sewage inside the open floor drain 3, and the self-cleaning module ensures the long-term operation of the filter system to avoid blockage problems. The gentle slope design of the bathroom floor 1 structure effectively guides water to the floor drain area to reduce water accumulation problems. The seepage holes and geotextile settings of the hidden floor drain body 32 and the filter residue box 39 ensure smooth seepage discharge to prevent groundwater backflow and odor. In addition, the hidden floor drain and filter residue box 39 in the mortar layer 36 are designed to achieve concealed drainage function without affecting the appearance, thereby increasing the overall appearance and practicality of the bathroom.

[0020] like Figures 2 to 9 As shown, the filter module includes a water collecting bucket 4 fixedly mounted on the top of the exposed floor drain 3, and a filter plate 5 fixedly mounted on the top of the exposed floor drain 3. Two opposite guide blocks 14 are arranged at the bottom of the exposed floor drain 3. The top surface of the filter plate 5 is arranged in a slope shape with high sides and low middle. A filter slot 7 is provided through the middle of the filter plate 5. The filter plates 5 are arranged circumferentially and equidistantly from the filter slots 7 and are provided with filter holes 8. By setting a water collecting bucket 4 at the top of the open floor drain 3, the sewage on the bathroom floor can be effectively collected to prevent the water from scattering. At the same time, the water collecting bucket 4 can guide the water flow directly into the filtration system. The top of the filter plate 5 is designed with a slope that is high on both sides and low in the middle. This structure can prompt the water flow to concentrate in the middle, which helps the sewage to enter the filter tank 7 in the middle for filtering treatment more quickly. The setting of the filter tank 7 and the design of the filter holes 8 arranged in a circle on the filter plate 5 ensure that the water flow can effectively filter impurities when passing through the filter plate 5, and prevent large particles from entering the sewer pipe. The setting of the guide block 14 further optimizes the water flow direction, so that the sewage can pass through the filter plate 5 smoothly, thereby improving the efficiency of the entire filtration process. This design not only effectively improves the drainage speed and reduces the possibility of blockage, but also improves the filtration effect, ensuring that the water quality entering the drainage system is relatively clean, thereby extending the service life of the drainage system.

[0021] like Figures 2 to 8 As shown, the self-cleaning module includes a retention box 10 fixedly installed in the middle above the water collecting bucket 4, and a cleaning box 15 fixedly installed on one side of the open floor drain 3. A plurality of water outlets 17 are provided on one side of the cleaning box 15, and the water outlets 17 are provided through the water collecting bucket 4. A movable plate 6 is provided below the filter plate 5. A first floating plate 11 is provided inside the retention box 10, and two connecting columns 13 are connected to the bottom end of the first floating plate 11. The two connecting columns 13 penetrate the retention box 10 and are fixedly connected to the filter plate 5 and the movable plate 6. A lifting column 9 adapted to the filter hole 8 is provided at the top of the movable plate 6. The lifting column 9 is hollow, and a top screen 25 is provided on the top surface of the lifting column 9. A side screen 26 is provided around the bottom of the lifting column 9. A plurality of through holes 12 are provided at both the upper and lower ends of the retention box 10. When the filter holes 8 of the filter plate 5 are blocked, sewage gradually accumulates in the water collecting bucket 4, and the water level gradually rises. In the process of gradually rising, sewage enters the retention box 10 from the through hole 12 at the bottom of the retention box 10, and gradually pushes the first floating plate 11 up in the process of rising water level. The connecting column 13 then drives the movable plate 6 and the lifting column 9 to lift upward. The lifting column 9 penetrates the filter hole 8 to push out the blocked filter residue, thereby cleaning the filter hole 8. After the lifting column 9 pushes out the filter residue, the water flow will fall through the side screen 26, which will not affect the flow of water. When the water level drops, the floating plate gradually resets and returns to its initial state, preparing for the next cleaning cycle. By setting the retention box 10 and the first floating plate 11, automatic cleaning of the filter module is achieved. When the filter plate 5 is blocked, the rising water level will automatically push the movable plate 6 to push out the blockage from the filter hole 8, thereby ensuring the smooth flow of the drainage system and reducing the maintenance frequency. A drainage port 38 is provided on one side of the top of the open floor drain 3, and the drainage port 38 is located above the filter plate 5. The filter slot 7 in the middle of the filter plate 5 is arranged in an inclined shape, and one end of the filter slot 7 is connected to the drainage port 38, and the other end of the drainage port 38 is connected to the filter residue box 39. A plurality of water inlet holes 16 are provided on one side of the water collecting bucket 4, and the water inlet holes 16 are provided on the top of the cleaning box 15. The top surface of the retention box 10 is in the same horizontal plane as the water inlet holes 16. A second floating plate 18 is provided inside the cleaning box 15, and two telescopic rods are provided at the bottom end of the second floating plate 18 to be connected to the bottom of the cleaning box 15.

As the water level rises, the second floating plate 18 rises to the pushing block 19 and contacts the positioning block 22 of the blocking block 21, pushing the blocking block 21 to move up, opening the water outlet 17, and the water stored in the cleaning box 15 rushes out through the water outlet 17 at a certain pressure, forming an interval cleaning state, reducing blockage under normal use. Water flows through the filter tank 7 and the drainage port 38 to bring the filter residue out of the system to avoid secondary blockage, and the blocking block 21 drives the opening and closing plate 24 to open upward synchronously through the connecting plate 23 during the rising process, opening the drainage port 38. Under normal conditions, the drainage port 38 is in a closed state and will only be opened synchronously during the interval flushing process. When the local drain is blocked, the water accumulates, and during the rising water level, it will also cooperate with the lifting column 9 to clean the ejected filter residue.

[0022] The present application also discloses a construction process for bathroom visible and hidden floor drains, which is applied to the above-mentioned bathroom visible and hidden floor drains, and includes the following steps: S1: accurately locate the main drain pipe 31 on the bathroom floor 1, and reserve the interface between the first outlet pipe 2 and the second outlet pipe 30; then, install the visible floor drain 3 and the hidden floor drain body 32, ensure that the hidden floor drain body 32 is buried in the mortar layer 36, and the visible floor drain 3 is connected to the first outlet pipe 2; S2: Lay a cushion layer 34, a waterproof layer 35, a mortar layer 36 and floor tiles 37 on the bathroom floor 1 in sequence; maintain a gentle slope of 5% between each layer of materials according to design requirements to naturally guide water to the floor drain area and reduce water accumulation problems; S3: Wrap the outer surface of the hidden floor drain body 32 and the filter box 39 with geotextile and integrate them with the mortar layer 36 to ensure the concealment and anti-seepage effect of the drainage system; adjust the top of the visible floor drain 3 and the filter box 39 to be flush with the floor tile 37 to ensure the overall aesthetics and practicality; S4: The toilet sewage enters the filter module inside the open floor drain 3 through the water collecting bucket 4.
