Description

Technical Field

[0001] The present application relates to the technical field of sanitary equipment, and in particular, to a narrow-edge large-capacity drainage floor drain. Background Art

[0002] A narrow-edge drainage floor drain is a commonly used sanitary facility in residences, usually laid in places such as bathrooms or balconies where the drainage volume is large in a short period of time to prevent excessive water accumulation on the ground. The narrow-edge drainage floor drain consists of two parts: a floor drain and a side groove, which are interconnected. In addition to realizing the drainage function, the floor drain can also prevent the backflow of sewage in the pipeline and the return of odors. The setting of the side groove is equivalent to expanding the volume of the floor drain and improving the ability of the floor drain to temporarily store water.

[0003] In the related art, in order to consider the aesthetics of the narrow-edge drainage floor drain, the width of the side groove is usually designed to be narrowed. After the narrow-edge drainage floor drain is laid, the part exposed on the ground is less, which can present a better visual effect and improve the compatibility of the narrow-edge drainage floor drain with the overall home decoration style.

[0004] However, the reduction of the width of the side groove also means the reduction of the volume, thus weakening the water storage capacity of the side groove and resulting in a decrease in the drainage capacity of the narrow-edge drainage floor drain. When there is a rainstorm on the balcony, it may occur that the rainwater cannot be discharged through the floor drain in time, and even cause serious water accumulation on the ground and backflow into the room. Summary of the Utility Model

[0005] In order to improve the problem of poor drainage capacity of the narrow-edge drainage floor drain and increase the flow rate of the floor drain, the present application provides a narrow-edge large-capacity drainage floor drain.

[0006] The narrow-edge large-capacity drainage floor drain provided by the present application adopts the following technical solutions:

[0007] A narrow-edge large-capacity drainage floor drain includes a sewage pipe, a storage tank, and a cover body for water supply overcurrent, and the sewage pipe is installed in the storage tank;

[0008] One or more widened grooves are connected to the storage tank, and the widened grooves are interconnected with the storage tank, and the cover body covers the upper part of the storage tank;

[0009] The height of the widened groove is less than the height of the storage tank.

[0010] By adopting the above technical solution, widened grooves that are interconnected are arranged beside the temporary storage groove, so that while maintaining the aesthetic appearance of the narrow-side design of the temporary storage groove, the overall volume of the floor drain is increased. When the floor drain encounters a large drainage volume, it can store more water, thereby reducing the risk of water accumulation and backflow on the ground. The height of the widened groove is lower than that of the temporary storage groove, making the overall cross-section in a stepped shape. When installing the floor drain, the ceramic tile can be covered above the lower widened groove, so that the part exposed on the ground is less. The width of the temporary storage groove still maintains a narrow design, which will not damage the harmony of the overall design and can be adapted to the home decoration style, improving the aesthetic appearance. The setting of the cover body enables water to flow through from above and also prevents sundries from entering the temporary storage groove.

[0011] Further, the temporary storage groove includes a drain trough and at least one side trough. The drain pipe is installed in the drain trough. The side trough is arranged on one side of the drain trough and is interconnected with both the drain trough and the widened groove.

[0012] The side trough includes a bottom plate and a side plate that are integrally connected. The bottom plate extends to one side of the widened groove. The width of the bottom plate is equal to the sum of the width of the side trough and the width of the widened groove. The bottom plate is bent along the length direction, and the bottom plate slopes downward from both sides to the central axis position.

[0013] By adopting the above technical solution, the drain trough is for installing the drain pipe. The side trough is connected to one side of the drain trough to increase the volume of the drain trough. The width of the bottom plate is equal to the sum of the width of the side trough and the width of the widened groove. The bottom plate is bent along the length direction, and the bottom plate slopes downward from both sides to the central axis position, so that the bottom plate can produce a guiding effect on the water flow. After the water flow enters the side trough and the widened groove, it can quickly flow into the drain pipe of the drain trough. The inclined bottom plate improves the drainage efficiency, reduces the residence time of the water flow in the side trough, and reduces the risk of water accumulation on the ground.

[0014] Further, a closing plate for closing the widened groove is arranged above the widened groove. The side of the closing plate away from the side trough is fixedly connected to the widened groove, and the side of the closing plate close to the side trough is fixedly connected to the outer wall of the side trough.

[0015] By adopting the above technical solution, the closing plate is fixedly connected to the widened groove to close the upper part of the widened groove. The side of the closing plate close to the side trough is fixedly connected to the outer wall of the side trough, enhancing the overall structural stability of the floor drain and making the widened groove and the side trough form a firm whole. On the one hand, it prevents sundries, dust or other pollutants from entering the widened groove, thus ensuring the smooth drainage and cleanliness of the floor drain. On the other hand, it also provides a support platform for laying ceramic tiles, isolating the ceramic tiles from the inside of the widened groove and preventing moisture from rising.

[0016] Further, the cover body includes a side groove grille for covering the side groove and a cover plate for covering the water outlet groove. The side groove grille includes a grille plate and side plates symmetrically arranged on both sides of the grille plate. Both side plates are perpendicular to and fixedly connected to the grille plate. A supporting column is fixedly connected to the inner wall of the side groove. When the side plate abuts against the inner wall of the side groove, the end face of the side plate close to the bottom of the side groove abuts against the supporting column;

[0017] The cover plate covers the water outlet groove.

[0018] By adopting the above technical solution, the side groove grille is used to cover the side groove and allow water to flow through, and the cover plate closes the water outlet groove. The side groove grille is composed of a grille plate and two side plates. The two side plates are perpendicular to the grille plate and symmetrically arranged on both sides thereof, ensuring the stability and strength of the grille, and at the same time preventing sundries from entering the sewer pipe and causing blockage. A supporting column is fixedly connected to the inner wall of the side groove. When the side plate abuts against the inner wall of the side groove, the end face of the side plate close to the bottom of the side groove abuts against the side wall of the supporting column. The supporting column provides additional support for the grille, ensuring the stability of the grille in the side groove and preventing the side groove grille from collapsing towards the bottom of the groove.

[0019] Further, the end of the supporting column far from the connection with the inner wall of the side groove extends below the closing plate, and the closing plate abuts against the upper part of the supporting column and is fixedly connected to the supporting column.

[0020] By adopting the above technical solution, the end of the supporting column far from the connection with the inner wall of the side groove extends below the closing plate, and the closing plate abuts against the upper part of the supporting column and is fixedly connected to the supporting column. The closing plate is firmly connected to the supporting column, forming a complete sealed structure with the side groove. The supporting column firmly supports the closing plate, preventing the widened groove from sagging or deforming due to uneven stress after laying tiles above.

[0021] Further, the side of the side plate far from abutting against the supporting column is flush with the height of the grille plate and the side groove.

[0022] By adopting the above technical solution, the end face of the side plate far from the supporting column is flush with the height of the grille plate and the side groove, ensuring the visual flatness and consistency of the floor drain. When the floor drain is installed, users will not observe obvious height differences or protruding parts above the floor drain, thereby improving the overall aesthetics. When cleaning the ground, since the height of the side plate is flush with the grille plate and the side groove, it is possible to more conveniently clean the dirt or sundries on the grille plate, helping to improve the cleaning efficiency and reduce the maintenance cost.

[0023] Further, a plurality of supporting blocks are fixedly connected to the inner wall of the water outlet groove, and the cover plate abuts against the side walls of the supporting blocks.

[0024] By adopting the above technical solution, several supporting blocks are arranged on the inner wall of the drain trough, and the cover plate is abutted against the side walls of the supporting blocks. The cover plate can obtain more stable and uniform support, which can effectively prevent the cover plate from deforming or shifting during use, thereby ensuring the sealing performance and stability of the floor drain. The installer only needs to place the cover plate on the supporting blocks and ensure that the cover plate is closely attached to the supporting blocks to confirm that the cover plate is installed in place, improving the installation efficiency.

[0025] Furthermore, an embedding groove for installing tiles is arranged on the side of the cover plate away from the side abutting against the supporting block.

[0026] By adopting the above technical solution, the setting of the embedding groove enables the tiles to be directly embedded in the cover plate, making the floor drain form a seamless connection with the surrounding floor tiles, which is more beautiful and unified visually, avoiding the problems of possible gaps and unevenness after the installation of traditional floor drains, and improving the overall decoration effect. The tiles are embedded in the embedding groove of the cover plate, forming a firm connection between the floor drain and the floor tiles, increasing the stability of the floor drain, and helping to prevent the floor drain from loosening or shifting due to long-term use or ground vibration. There is a seamless connection between the floor drain and the tiles, and it is not easy to accumulate dirt and debris, making cleaning and maintenance more convenient. The user only needs to clean the floor tiles in the normal way without additional treatment of the area around the floor drain.

[0027] Furthermore, the drainage pipe has a water inlet port, and a grille cover for water to flow through is provided at the water inlet port of the drainage pipe. The grille cover is fixedly connected to the drainage pipe by clamping, and the grille cover is lower than / flush with the bottom of the drain trough.

[0028] By adopting the above technical solution, the grille cover is fixedly connected to the drainage pipe by clamping, and the grille cover is flush with the bottom of the drain trough, which can prevent the grille cover from being displaced by the impact of water flow, thereby blocking pollutants from entering at the water inlet port position and preventing the inside of the drainage pipe from being blocked.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The widened trough increases the overall volume of the floor drain, can temporarily store more water in the case of large drainage volume, reduces the risk of floor water accumulation and backflow. The height of the widened trough is lower than that of the side trough, and the overall cross-section is in a stepped shape, so that the part exposed on the ground is less. The width of the side trough is designed to be narrow, which not only improves the volume of the floor drain but also maintains the aesthetics and can be adapted to the home decoration style;

[0031] 2. The side groove grille is covered on the side groove, which not only allows water to flow through but also prevents debris from entering. The cover plate is covered on the drain trough to seal the drain trough. The embedding groove on the cover plate also enables the ceramic tile to be directly embedded into the cover, achieving seamless connection with the surrounding floor tiles, which is not only beautiful but also convenient for cleaning and maintenance.

[0032] 3. The grille cover is flush with the bottom of the drain trough, preventing the displacement of the grille cover caused by the impact of water flow, blocking pollutants from entering, preventing blockage inside the drainage pipe, and at the same time reducing the water flow resistance and accelerating the drainage speed.

Detailed Embodiments

[0039] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings, Embodiment 1 and Embodiment 2.

[0040] Embodiment 1

[0041] The present application discloses a narrow-edge large-capacity drainage floor drain in an embodiment. In this embodiment, terms such as "upper" and "lower" used to express positional relationships are determined with reference to the placement and installation positions of the narrow-edge large-capacity drainage floor drain in its normal use state.

[0042] Refer to Figure 1and Figure 2 A narrow-edge large-capacity drainage floor drain includes a drainage pipe, a temporary storage tank 2, a widened groove 4 and a cover body 3. The temporary storage tank 2 includes a water drainage groove 21 and at least one side groove 22. The drainage pipe is installed in the water drainage groove 21. In this embodiment, the number of side grooves 22 is two and they are arranged on both sides of the water drainage groove 21, and the water drainage groove 21 is in communication with the side grooves 22. The widened groove 4 is adjacent to the side groove 22 and has the same length. The widened groove 4 is in communication with both the side groove 22 and the water drainage groove 21.

[0043] In this embodiment, the height of the widened groove 4 is less than the height of the side groove 22. A closing plate 41 is arranged above the widened groove 4, and one side of the closing plate 41 is integrally connected to the side of the widened groove 4 away from the side groove 22. The side groove 22 includes a bottom plate 221 and a side plate 222 which are integrally connected. The side of the closing plate 41 close to the side groove 22 extends vertically upward, and the extending height is flush with the height of the side plate 222. End plates 223 are arranged at the end positions of the side groove 22 and the widened groove 4 away from the connection with the water drainage groove 21. The end plates 223 are perpendicular and fixedly connected to the side plate 222, the bottom plate 221 and the closing plate 41 respectively.

[0044] Refer to Figure 3 and Figure 4 In this embodiment, the bottom plate 221 slopes downward from both sides to the center line in the length direction, and the cross-section of the bottom plate 221 is V-shaped. When water flows into the side groove 22, the bottom plate 221 forms a guiding effect on the water flow, so that the water flow quickly flows into the water drainage groove 21 and then into the drainage pipe.

[0045] Refer to Figure 2 and Figure 3 In this embodiment, the drainage pipe has an inlet port 11 for water to pass through. A grille cover 12 is provided at the inlet port 11 of the drainage pipe. The grille cover 12 is fixedly connected to the drainage pipe by clamping. The height of the grille cover 12 is consistent with the height of the bottom of the temporary storage tank 2. An anti-backflow air floor drain 13 is also arranged at the position of the water drainage pipe 1 in this embodiment, and the anti-backflow air floor drain 13 can be selectively installed according to actual use requirements.

[0046] Refer to Figure 2 In this embodiment, the cover body 3 includes a side groove 22 grille and a cover plate 32. The cover plate 32 covers the temporary storage tank 2. The side groove 22 grille cover 12 covers the side groove 22 and allows water to flow through. An embedding groove 321 for installing tiles is provided on the cover plate 32. The side groove 22 grille includes a grille plate 311 and side plates 312 symmetrically arranged on both sides of the grille plate 311. Both side plates 312 are vertically and fixedly connected to both sides of the grille plate 311.

[0047] On the inner wall of the temporary storage groove 2, a supporting block 211 is vertically arranged. When the cover plate 32 covers the temporary storage groove 2, the side wall of the cover plate 32 abuts against the inner wall of the temporary storage groove 2, and the lower part of the cover plate 32 abuts against the supporting block 211. On the side plate 222 of the side groove 22, a supporting column 224 is vertically and fixedly connected. The end of the supporting column 224 far from the connection with the side plate 222 extends towards the side of the closing plate 41. When the grille cover 12 of the side groove 22 covers the side groove 22, the sides of the two side plates 312 close to the bottom plate 221 abut against the supporting column 224.

[0048] Referring to Figure 2 and Figure 4 , in this embodiment, the end of the supporting column 224 far from the connection with the side plate 222 extends below the closing plate 41, and the bottom of the closing plate 41 abuts against the supporting column 224. The closing plate 41 can be threadedly fixed to the supporting column 224 through connecting parts such as bolts.

[0049] Combined with Figure 1 , in this embodiment, the number of the side grooves 22 is two. The two side grooves 22 are arranged perpendicular to each other and are respectively located on the adjacent sides of the temporary storage groove 2, so that the narrow-side large-capacity drainage floor drain can meet the drainage requirements at the corner position.

[0050] The implementation principle of a narrow-edge large-capacity drainage floor drain in an embodiment of the present application is as follows: The drainage pipe is located in the water outlet trough 21 of the temporary storage trough 2 and receives water through the water inlet port 11. The water outlet trough 21 is used to temporarily store the water flowing in from the drainage pipe and is interconnected with the drainage pipe, the side trough 22, and the widened trough 4. The side trough 22 and the widened trough 4 are arranged beside the water outlet trough 21. By setting the widened trough 4, the volume of the side trough 22 is increased, and the part of the side trough 22 exposed on the ground can still maintain a narrow-edge design to maintain aesthetics. A closing plate 41 is arranged above the widened trough 4 to close the upper space of the widened trough 4 to prevent sundries from entering and at the same time provide a support platform for laying tiles. The cover body 3 includes a side trough 22 grille and a cover plate 32, which are respectively used to cover the side trough 22 and the water outlet trough 21. The side trough 22 grille allows water to pass through and prevents sundries from entering. An embedding groove 321 is provided on the cover plate 32 for installing tiles. A supporting block 211 arranged on the inner wall of the water outlet trough 21 provides support for the cover plate 32 to ensure that the cover plate 32 is stably covered on the water outlet trough 21. A supporting column 224 is vertically fixed on the side plate 222 of the side trough 22 to support the side trough 22 grille and ensure that the grille is stably covered on the side trough 22. The supporting column 224 is fixed to the closing plate 41 through connecting pieces such as bolts to form a complete sealed structure, and at the same time, the closing plate 41 can also stably support the tiles laid above. The bottom plate 221 is bent along the length direction and slopes downward from both sides to the central axis position, forming a V-shaped cross-section. When water flows into the side trough 22, the bottom plate 221 can guide the water to quickly flow into the water outlet trough 21 and enter the water inlet port 11 of the drainage pipe. The side trough 22 maintains a narrow-edge design, adapts to the home decoration style, and improves aesthetics. The embedding groove 321 provided on the cover plate 32 allows the tiles to be directly embedded, realizing seamless connection with the surrounding floor tiles and enhancing the decoration effect. The widened trough 4 increases the volume of the drainage pipe, reduces the risk of water accumulation and backflow on the ground, and at the same time maintains the harmony of the appearance of the drainage pipe.

[0051] Embodiment 2

[0052] The difference between the embodiment of the present application and Embodiment 1 is that the number of side troughs 22 in this embodiment is two, and the two side troughs 22 are respectively arranged on opposite sides of the water outlet trough 21, and the side trough 22 and the water outlet trough 21 are arranged in a straight line as a whole, so that the narrow-edge large-capacity drainage floor drain is suitable for linear installation occasions.

[0053] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
