Description

Technical Field

[0001] The utility model relates to the technical field of interior decoration, in particular to a drainage pipe fitting for an assembled integral bathroom chassis. Background Art

[0002] The existing integral chassis of a bathroom is made by a customized mold to ensure a 1% drainage slope in the wet area. The drainage branch pipe runs through the overhead layer under the chassis and is molded according to the project for industrial production. For example, a quick-install bathroom chassis structure applied to an integral bathroom disclosed in Chinese Patent CN209966220U includes a bottom plate, a filling layer installed on the bearing surface of the bottom plate, a buffer layer provided on the filling layer, and a cement ash layer provided on the buffer layer. Floor tiles are pasted on the cement ash layer. A support assembly is provided at the bottom of the bottom plate to support the bottom plate so that the bottom plate is spaced from the ground by a predetermined distance. The support assembly includes a bearing plate provided at the bottom end surface of the bottom plate, symmetric support plates welded on both sides of the bearing plate and perpendicular to the bearing plate, and a reinforcing bar connected between the support plates. In the foregoing prior art, by providing a filling layer, a buffer layer and a cement ash layer on the bottom plate, the stability of the entire chassis structure can be enhanced. By setting floor tiles on the cement ash layer, the floor tiles can be pre-laid, thus saving the process of laying floor tiles on site and making the installation of the chassis more time-saving and labor-saving. The provided support assembly can make the bottom plate spaced from the ground by a certain distance, facilitating the installation of drainage pipes and lines.

[0003] However, the following problems still exist in the foregoing prior art:

[0004] 1) The bottom plate and the drainage pipe are still in a split form and do not truly form an integrated body;

[0005] 2) The drainage pipe is laid on the ground of the bathroom space under the bottom plate. If there is a leakage situation caused by loose connection or damage of the drainage pipe under the bottom plate, the entire chassis needs to be lifted for maintenance, which is very inconvenient for maintenance;

[0006] 3) This drainage pipeline laying method occupies the ground space of the bathroom, and the laying distance of the drainage branch pipe is also limited. Content of the Utility Model

[0007] The utility model aims to provide a drainage pipe fitting for an assembled integral bathroom chassis to solve the deficiencies existing in the prior art. The technical problems to be solved by the utility model are realized through the following technical solutions.

[0030] Embodiment 1:

[0031] Referring to Figure 1 and Figure 2 As shown, a drainage pipe fitting for an assembled integral bathroom chassis is characterized in that it includes a bottom support 1, a drainage layer and a surface layer 4. The bottom support 1 is placed on the ground of the bathroom space. A drain hole I 12 is provided on one side wall of the bottom support 1. The drainage layer includes a drainage module 2 and a filling module 3. The drainage module 2 is placed above the bottom support 1 and is arranged in a frame structure along the inner side edge of the bottom support 1. The drainage module 2 includes a drainage pipe fitting body 21 and a cover plate 22. The upper end of the drainage pipe fitting body 21 is open. A drain port I 2161 matching the drain hole I 12 is provided on the outer side wall of the drainage pipe fitting body 21. The drainage groove in the drainage pipe fitting body 21 slopes downward towards the drain port I 2161. The cover plate 22 is hermetically covered on the upper end of the drainage pipe fitting body 21, and a drain hole II 221 is provided on the cover plate 22. A filling module 3 is provided at the part of the bottom support 1 inside the drainage module 2. The outer side wall of the filling module 3 is attached to the inner side wall of the drainage module 2. The height of the filling module 3 matches the height of the side wall of the drainage pipe fitting body 21. A number of protrusions are provided on the upper end surface of the filling module 3, and a downwardly concave drainage groove is formed between adjacent protrusions. The drainage groove as a whole slopes towards a corner of the drainage module 2, and a drainage fitting 34 connecting the drainage groove and the drainage pipe fitting body 21 is provided at the lowest part of the drainage groove. The surface layer 4 is hermetically covered above the drainage layer, and a floor drain groove 41 is provided on the surface layer 4, and the floor drain groove 41 matches the drain hole II 221.

[0032] In this embodiment, the bottom bracket 1 serves as the bottom supporting part of the integral bathroom chassis, and is used to support the containers of the drainage module 2, the filling module 3 and the surface layer 4. During assembly, a drainage hole I12 is opened at a position on the side wall of the bottom bracket 1 corresponding to the drainage riser on the bathroom floor to be paved. The drainage pipe fitting body 21 is installed along the edge of the bottom bracket 1, and the drainage port I2161 on the drainage pipe fitting body 21 extends out from the drainage hole I12 of the bottom bracket 1. Then, the filling module 3 is installed at the idle position in the middle of the drainage module 2 inside the bottom bracket 1 and is closely attached to the side wall of the drainage pipe fitting body 21. A drainage fitting 34 is installed at the lowest point of the drainage groove of the filling module 3, so that the water collecting tray of the drainage fitting 34 is placed at the lowest point of the drainage groove of the filling module 3, and the water outlet pipe of the drainage fitting 34 passes through the inner side wall of the drainage pipe fitting body 21 and is placed in the drainage groove of the drainage pipe fitting body. Then, the cover plate 22 and the drainage pipe fitting body 21 are hermetically covered. A bayonet is reserved at the upper end of the drainage pipe fitting body 21, and the cover plate 22 and the drainage pipe fitting body 21 are clamped with each other, and the gap is sealed with a U-shaped sealing strip. Finally, the surface layer 4 is installed. The surface layer 4 includes a bottom plate and side plates vertically arranged at the four edges of the bottom plate. The outer side walls of the side plates of the surface layer 4 should be aligned with the outer side walls of the bottom bracket 1. A rubber and plastic heat preservation pad is pasted on the bottom of the bottom plate, which is convenient for leveling between the bottom plate and the drainage module 2 on the one hand, and plays a role in shock absorption on the other hand. Finally, a lock catch 11 is installed on the side walls of the bottom bracket 1 and the surface layer 4 to ensure the stability of the integral bathroom chassis during transportation.

[0033] The assembled integral bathroom chassis is transported to the bathroom space to be paved as a finished product. The lock catch 11 is removed, and the integral bathroom chassis is placed on the bathroom space floor, and the drainage port I2161 is hermetically connected to the drainage riser on the ground. A floor drain groove 41 is provided on the surface layer 4 and is used as the main drainage channel of the bathroom. The floor drain groove 41 matches the drainage hole II221 on the cover plate 22, and a floor drain is installed on the floor drain groove 41. The lower end of the floor drain passes through the drainage hole II221 and is placed in the drainage groove of the drainage pipe fitting body 21. During drainage, the water on the bathroom space floor first drains into the drainage groove of the drainage pipe fitting body 21 through the floor drain, and converges in the drainage groove, and finally drains out from the drainage port I2161 at the lowest point of the drainage groove of the drainage pipe fitting body 21. If the surface layer 4 is damaged or leaks, the water on the bathroom floor will flow into the drainage groove of the lower filling module 3, converge to the lowest point in the drainage groove of the filling module 3, and be introduced into the drainage groove of the drainage pipe fitting body 21 by the drainage fitting 34, and finally drain out from the drainage port I2161, avoiding water seeping into the floor structure layer and damaging the floor.

[0034] Furthermore, the upper surfaces of the protrusions are flush with each other.

[0035] Embodiment 2:

[0036] On the basis of Embodiment 1, with reference to Figure 3As shown, the drainage pipe fitting body 21 includes a right-angle fitting, a linear pipe fitting 215, and a side drainage pipe fitting 216. The right-angle fittings are respectively arranged at the four corners of the bottom bracket 1, the linear pipe fittings 215 are respectively arranged at the four sides of the bottom bracket 1, and the side drainage pipe fitting 216 is arranged between two of the linear pipe fittings 215 on one side of the bottom bracket 1. The right-angle fittings, the linear pipe fittings 215, and the side drainage pipe fitting 216 are interconnected to form a frame-shaped groove as a whole, and the overall drainage groove after connection is inclined downward toward the drainage port I2161. The drainage port I2161 is arranged on the outer side wall of the side drainage pipe fitting 216, and the drainage port I2161 is mutually matched with the drainage hole I12 on the bottom bracket 1.

[0037] Further, the bottom surfaces of the cross-sections of the right-angle fitting, the linear pipe fitting, and the side drainage pipe fitting 216 are all V-shaped.

[0038] Further, the right-angle fitting includes right-angle fitting I211, right-angle fitting II212, right-angle fitting III213, and right-angle fitting IV214 respectively placed at the four corners of the bottom bracket 1. The right-angle fitting I211, right-angle fitting II212, right-angle fitting III213, and right-angle fitting IV214 and the adjacent linear pipe fitting 215 are hermetically clamped through a male-female joint.

[0039] Further, the height of the V-shaped groove formed by the bottom surfaces of the right-angle fitting I211, right-angle fitting II212, right-angle fitting III213, and right-angle fitting IV214 gradually decreases from one end surface to the other end surface, wherein the lower side is close to the side drainage pipe fitting 216.

[0040] Further, the height of the V-shaped groove formed by the bottom surface of the linear pipe fitting 215 gradually decreases from one end surface to the other end surface, wherein the lower side is close to the side drainage pipe fitting 216.

[0041] Further, the number of linear pipe fittings arranged at each side of the bottom bracket 1 is one or more, depending on the size of the bathroom space.

[0042] Further, the V-shaped groove formed by the bottom surface of the side drainage pipe fitting 216 has a structure with higher sides and a lower middle; further, the drainage port I2161 is arranged at the lowest part of the bottom surface of the side drainage pipe fitting 216.

[0043] In this embodiment, the settings of the right-angle fitting I211, right-angle fitting II212, right-angle fitting III213, right-angle fitting IV214, the side drainage pipe fitting 216, and the linear pipe fitting 215 make the overall drainage groove formed by the drainage pipe fitting body 21 after sealed splicing inclined downward toward the side drainage pipe fitting 216, so that the water discharged into the drainage pipe fitting body 21 is gathered at the drainage port I2161 and discharged by the floor drainage vertical pipe.

[0044] Furthermore, at least two check valve flap members 217 are provided inside the drainage pipe fitting body 21, and the check valve flap members 217 open towards the side drainage pipe fitting 216 and close in the reverse direction.

[0045] In this embodiment, the arrangement of the check valve flap members 217 can prevent the water originally retained in the drainage pipe fitting body 21 from being flushed away in a direction away from the drainage port I2161 due to the impact of the water flow discharged into the drainage pipe fitting body 21, so that the water is restricted to gather near the side drainage pipe fitting 216, making the drainage effect better. If water leaks into the position in the drainage pipe fitting body 21 far from the side drainage pipe fitting 216 due to the damage of the surface layer 4, the water flow will gather towards the side drainage pipe fitting 216, and the check valve flap members 217 will allow the water flow to flow into the side drainage pipe fitting 216. In addition, the check valve flap members 217 also have the function of preventing odors.

[0046] Embodiment 3:

[0047] On the basis of Embodiment 1 or 2, referring to Figure 4 and Figure 5 as shown, the filling module 3 includes a number of square unit blocks spliced together. Sector-shaped protrusions are provided at the four corners of the unit blocks, and downwardly concave drainage grooves are formed between adjacent protrusions. The bottom of the drainage groove on the unit block is parallel to the horizontal plane, or slopes downward along one side of the unit block, or slopes downward along the diagonal of the unit block, so that after the unit blocks are spliced together, the overall drainage groove is continuously docked and slopes downward towards a corner of the filling module 3.

[0048] Furthermore, the unit blocks include flat unit blocks 31, double-sided inclined unit blocks 32, and diagonal inclined unit blocks 33. The bottom of the drainage groove of the flat unit block 31 is parallel to the horizontal plane. The bottom of the drainage groove of the double-sided inclined unit block 32 slopes downward along one side of the double-sided inclined unit block 32. The bottom of the drainage groove of the diagonal inclined unit block 33 slopes downward along the diagonal of the diagonal inclined unit block 33. After the flat unit blocks 31, double-sided inclined unit blocks 32, and diagonal inclined unit blocks 33 are spliced together to form the filling module 3, the drainage grooves of the unit blocks are continuously docked and slope towards the flat unit block 31.

[0049] In this embodiment, the upper end surfaces of the flat unit blocks 31, double-sided inclined unit blocks 32, and diagonal inclined unit blocks 33, that is, the upper end surfaces of the bosses, are flush with each other. The bottom surface of the drainage groove of the flat unit block 31 is horizontal, and the bottom surface of the drainage groove of the flat unit block 31 is the lowest point of the bottom surface of the drainage groove of the entire filling module 3. Referring to Figure 4As shown, taking the filling module 3 assembled by splicing 8 unit blocks in a two-row and four-column form as an example, from left to right, the left two columns are four double-sided inclined unit blocks 32. In the third column, the first row is a double-sided inclined unit block 32 and the second row is a diagonal inclined unit block 33. In the fourth column, the first row is a flat unit block 31 and the second row is a double-sided inclined unit block 32. The bottom surface of the drainage groove of the double-sided inclined unit block 32 in the first column on the left is higher than the bottom surface of the drainage groove of the double-sided inclined unit block 32 in the second column on the left, so that the rightmost end of the bottom surface of the drainage groove of the double-sided inclined unit block 32 in the first column on the left is flush with the leftmost end of the bottom surface of the drainage groove of the double-sided inclined unit block 32 in the second column on the left, so that the bottom surfaces of the drainage grooves of the unit blocks in the first column on the left and the second column on the left are smoothly transitioned and inclined. Similarly, the bottom surfaces of the drainage grooves of the unit blocks in the second column, the third column, and the fourth column are also smoothly transitioned and inclined, so that the water falling into the drainage groove of the filling module 3 converges to the flat unit block 31 and is discharged into the drainage pipe fitting body 21 through the drainage fitting. That is to say, the upper and lower end surfaces of the unit block are both horizontal and flush with each other, but the bottom slopes of the drainage grooves of different unit blocks are the same and the heights are different. During processing, the unit blocks with drainage grooves of different heights are marked differently, and the number and type of unit blocks are determined according to the size of the on-site bathroom space floor, so as to be spliced into a filling module with the drainage groove inclined towards one corner as a whole. When actually selecting the unit block, one or several of the flat unit block 31, the double-sided inclined unit block 32, and the diagonal inclined unit block 33 can be selected according to needs, not limited to Figure 4 the combination shown in

[0050] Further, the inclination slope of the drainage groove of the filling module 3 is 12‰.

[0051] Further, the water accumulation tray of the drainage fitting 34 is placed in the drainage groove of the flat unit block 31, and the water outlet pipe is placed in the drainage pipe fitting body 21. A check valve is provided on the water outlet pipe, and the check valve opens from the water accumulation tray to the water outlet of the water outlet pipe and closes in the reverse direction.

[0052] In this embodiment, the water accumulation tray is used to collect the water flow in the drainage groove of the filling module 3 and discharge it into the drainage groove of the drainage pipe fitting body 21 through the water outlet pipe. The setting of the check valve on the water outlet pipe only allows the water flow to flow from the drainage groove of the filling module 3 to the drainage groove of the drainage pipe fitting body 21, and is cut off in the reverse direction, so that the water flow in the filling module 3 and the drainage pipe fitting body 21 can be better collected and discharged at the drainage port I2161, avoiding long-term water accumulation in the bathroom chassis.

[0053] Further, the bottom bracket 1 is made of one of the materials of polypropylene, resin, and ABS.

[0054] Further, when the bottom tray 1 is made of polypropylene material, its thickness is not less than 5 mm. When the bottom tray 1 is made of resin or ABS material, its thickness should be not less than 4 mm.

[0055] Further, the height of the drainage pipe fitting body 21 is 90 - 100 mm.

[0056] Further, the height of the V-shaped groove on the bottom surface of the drainage trough of the drainage pipe fitting body 21 is not less than 30 mm.
