Description
Technical Field
[0001] The utility model relates to the technical field of bathrooms, in particular to a toilet drainage connection flange and a toilet using the same. Background Art
[0002] The pit distance is the distance between the wall against which the back of the toilet rests and the center point of the drain outlet used for toilet drainage. This pit distance is fixed, so the position of the drain outlet when the toilet is produced is matched with the pit distance. Therefore, consumers need to confirm with the plasterer repeatedly by phone before purchasing the toilet. When the pit distance deviates due to problems with wall tiles during decoration, the toilet cannot be installed, making it inconvenient to install. Furthermore, each country has a fixed standard for pit distance, and China has two fixed standards for pit distance. This requires manufacturers to manufacture molds according to the production of toilets with different pit distances, which results in high production costs.
[0003] In response to the above problems, when installing toilets that do not match the pit distance, workers will choose to use a shifter to connect the toilet drain outlet with the ground drain outlet. However, since the shifter has multiple turning bends, the air pressure in the pipe increases, which can easily cause backflow, resulting in poor drainage. In addition, due to the increase in bends, dirt is also easily retained in the pipe, increasing the risk of blockage. In addition, in order to install the shifter, it is sometimes necessary to raise the ground, which not only increases the difficulty of construction, but also may affect the overall appearance and comfort of the bathroom. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0035] The following is combined with Figures 1 to 6 The technical solution of the utility model is further illustrated by specific implementation methods.
[0036] A toilet drainage connection flange, comprising a connection plate 11, an upper drainage butt joint pipe 12 and a lower drainage butt joint pipe 13;
[0037] The upper sewage-discharge butt joint pipe 12 is arranged on the top surface of the connecting plate 11, and the lower sewage-discharge butt joint pipe 13 is arranged on the bottom surface of the connecting plate 11. The upper sewage-discharge butt joint pipe 12 and the lower sewage-discharge butt joint pipe 13 are eccentrically arranged front and back, and there is an overlapping part between the upper sewage-discharge butt joint pipe 12 and the lower sewage-discharge butt joint pipe 13 in the vertical direction. The connecting plate 11 is provided with a through hole 10 at a position corresponding to the overlapping part, and the through hole 10 connects the upper sewage-discharge butt joint pipe 12 and the lower sewage-discharge butt joint pipe 13;
[0038] The upper sewage discharge butt joint pipe 12 is used to be connected to the sewage outlet of the toilet, and the lower sewage discharge butt joint pipe 13 is used to be connected to the ground sewage pipe 9.
[0039] The connection flange 1 of the utility model is used for connecting the sewage outlet of the toilet with the sewage pipe on the ground. The connection flange 1 includes an upper sewage butt joint pipe 12 and a lower sewage butt joint pipe 13 which are respectively connected to the top surface of the connection plate 11 and the ground. By adopting the design of eccentric axis of two functional pipes and opening a through hole 10 at the overlapping part of the two functional pipes on the connection plate 11, the installation application range of the toilet is improved.
[0040] Since the upper sewage discharge butt joint pipe 12 and the lower sewage discharge butt joint pipe 13 are arranged relative to each other in the front and back direction, in the actual installation and application process, it is only necessary to simply swap the relative front and back directions of the upper sewage discharge butt joint pipe 12 and the lower sewage discharge butt joint pipe 13 to easily switch between different pit distances such as 250 / 300mm or 350 / 400mm, which greatly improves the flexibility and convenience of installation. Figure 5 When the connecting flange 1 is installed at the bottom of the toilet, the lower sewage butt pipe 13 is relatively located behind the upper sewage butt pipe 12, and the connecting flange 1 can cover the sewage pipe with a pit distance (the distance from the center of the sewage pipe to the wall) of S1 to S2; refer to Figure 6, the lower sewage butt joint 13 of the connection flange 1 is relatively located in front of the upper sewage butt joint 12, and the connection flange 1 can cover the sewage pipe with a pit distance (the distance from the center of the sewage pipe to the wall) of S3 to S4. Specifically, S1 is 250mm, S2 is 300mm, S3 is 350mm, and S4 is 400mm, which is equivalent to when the connection flange 1 is in Figure 5 When the installation state is set, the toilet can be installed in a site with a pit distance of 250 / 300mm. When the connecting flange 1 is in Figure 6 When the toilet is installed in the installation state, it can meet the installation requirements of the site with a pit distance of 350 / 400mm. At the same time, the toilet has a high fault tolerance during terminal installation and can even be installed in a wide range of pit distances of 230-420mm, which provides a great adjustment space for actual construction and effectively solves the installation problems caused by pit distance deviation.
[0041] Furthermore, the upper sewage discharge butt joint pipe 12 is perpendicular to the connecting plate 11 and extends upward, and the lower sewage discharge butt joint pipe 13 is perpendicular to the connecting plate 11 and extends downward.
[0042] The upper sewage butt joint pipe 12 and the lower sewage butt joint pipe 13 are both arranged perpendicular to the connecting plate 11, so that the entire connecting flange 1 is more reasonable and compact in spatial layout, which helps to reduce the space required for installation and makes the connection more concise and efficient.
[0043] Since both the upper and lower sewage pipes are kept vertical, this helps maintain the smoothness of the toilet sewage pipe. Compared with the curved pipe structure of other shifters, this design reduces the resistance and obstacles in the sewage discharge process, thereby maintaining the good sewage discharge performance of the toilet.
[0044] Furthermore, the height D of the connecting flange 1 is 30 mm-36 mm.
[0045] Compared with the shifter structure currently used in the market, the connecting flange 1 of the utility model is more compact and can be more compactly adapted to the bathroom environment with limited space. This is particularly important for families with small apartments or compact bathroom areas, and can save precious space resources.
[0046] Furthermore, the thickness D1 of the connecting plate 11 is 10 mm-13 mm.
[0047] The thickness D1 of the connecting plate 11 in the range of 2 mm to 4 mm can significantly improve the bending, shear and compression resistance of the connecting plate, thereby enhancing the structural stability of the entire connecting flange 1. This is essential for bearing the weight of the toilet, the pressure of the drainage pipe, and possible external shocks or vibrations. The connecting plate 11 with a certain compression resistance can better resist deformation caused by long-term use or external factors, ensuring that the connecting flange always remains flat and tightly fitted, thereby ensuring the sealing effect.
[0048] Furthermore, the minimum aperture of the through hole 10 is greater than Φ42 mm.
[0049] The minimum aperture of the through hole 10 is greater than Φ42mm, which means that the drainage channel is more spacious and can accommodate more water flow. This helps to quickly and smoothly discharge sewage when the toilet is flushed, reduce backflow or blockage caused by water flow obstruction, and thus improve drainage efficiency. Ensuring the aperture of the through hole 10 allows the connecting flange 1 to more effectively discharge larger or harder dirt when facing it, reducing the risk of blockage caused by dirt accumulation. This is of great significance for ensuring the normal use of the toilet and reducing maintenance costs.
[0050] Furthermore, the horizontal cross-section of the upper sewage discharge butt joint 12 is circular, rectangular or elliptical.
[0051] Since the horizontal cross-section of the upper sewage pipe is designed as a symmetrical shape such as a circle, rectangle or oval, these shapes have the same size and shape in the front and back directions. Therefore, when the relative position between the toilet and the ground sewage pipe needs to be adjusted (for example, to match different pit distances), the front and back positions of the connecting flanges can be simply interchanged without worrying about the shape or size mismatch of the pipe. This interchangeability greatly improves the flexibility and convenience of installation.
[0052] Furthermore, sealing rings 14 are respectively provided on the outer sides of the upper sewage discharge butt joint pipe 12 and the lower sewage discharge butt joint pipe 13 .
[0053] The sealing ring is set on the outer side of the upper sewage butt pipe and the lower sewage butt pipe, which can significantly improve the sealing performance between the connecting flange and the toilet sewage outlet and the ground sewage pipe. The sealing ring can fit tightly between the butt pipe and the connection port, effectively preventing sewage leakage and odor emission, and keeping the bathroom clean and comfortable. The addition of the sealing ring makes the installation process more standardized. During installation, workers can ensure that the sealing ring is correctly installed in place, thereby avoiding water leakage caused by improper installation. This helps to improve the overall installation quality and reduce the frequency of later repairs and replacements.
[0054] Another embodiment of the present invention provides a toilet, comprising an integrally formed barrel body 2, a sewage discharge channel and a sewage discharge docking portion 3, wherein the two ends of the sewage discharge channel are respectively connected to the barrel body 2 and the sewage discharge docking portion 3, and the sewage discharge docking portion 3 is located at the bottom of the toilet;
[0055] The sewage discharge docking portion 3 is connected to the above-mentioned connecting flange 1 .
[0056] The standardized design of the sewage docking part 3 and the connecting flange 1 makes the installation process simpler and faster. The installer only needs to align and fix the sewage docking part 3 with the connecting flange 1, without complicated adjustment and measurement steps. Further, since the connecting flange 1 is installed at the bottom of the toilet and does not involve key functional areas such as the S-bend, it will not have any negative impact on the flushing and sewage discharge function of the toilet, ensuring the normal use of the toilet and a good sewage discharge effect.
[0057] By designing a standardized sewage docking portion 3 and a connecting flange 1, the toilet can be adapted to installations with different pit distances, has a wide range of installation applications, and improves the versatility of the product.
[0058] The one-piece design of the barrel body 2, the drainage channel and the drainage docking part 3 makes the various parts of the toilet closely connected to form a whole, thereby enhancing the structural strength of the toilet. The one-piece design realizes seamless connection and reduces the problem of water leakage caused by loose connection. The tight sealing can also effectively prevent odor from escaping from the drainage system, improving the comfort and sanitary conditions of use.
[0059] Furthermore, an upper sewage outlet 31 is provided at the top of the sewage discharge docking portion 3, a lower sewage outlet 32 is provided at the bottom of the sewage discharge docking portion 3, and a cavity 30 is provided inside the sewage discharge docking portion 3, and the cavity 30 communicates with the upper sewage outlet 31 and the lower sewage outlet 32;
[0060] The upper sewage connection port 31 is connected to the lower port of the sewage discharge channel;
[0061] The upper sewage discharge butt joint pipe 12 is embedded in the lower sewage discharge port 32 .
[0062] The design of the sewage docking part 3 makes the sewage system of the toilet more reasonable. The upper sewage connection port 31 is directly connected to the lower port of the sewage channel, ensuring that the sewage can be smoothly discharged from the barrel body 2 into the sewage docking part 3, and then discharged through the lower sewage outlet 32. This design reduces the residence time and accumulation of sewage inside the toilet, which is conducive to keeping the toilet clean and hygienic. The upper sewage docking pipe 12 is embedded in the lower sewage outlet 32. This embedded connection method helps to enhance the sealing between the sewage docking part 3 and the connecting flange 1. Through close contact and the assistance of possible sealing materials (such as sealing rings), sewage leakage and odor emission can be prevented, and the safety and comfort of use can be improved. The design of arranging a cavity 30 inside the sewage docking part 3 helps to reduce the amount of material used, thereby reducing the overall quality of the toilet. This not only reduces production costs and transportation costs, but also makes the toilet lighter during installation and movement, improving user experience.
[0063] Further, the opening shape of the lower sewage outlet 32 matches the shape of the horizontal cross section of the upper sewage butt joint 12;
[0064] When the sewage outlet 31 is assembled and connected with the upper sewage discharge butt joint pipe 12 , the bottom surface of the sewage discharge butt joint portion 3 abuts against the top surface of the connecting plate 11 .
[0065] The opening shape of the lower sewage outlet 32 matches the horizontal cross-sectional shape of the upper sewage outlet butt joint 12. This design ensures that the two can fit tightly during assembly, reducing the presence of gaps and clearances. The tight fit design effectively prevents sewage and odor from leaking from the interface, improves the sealing performance of the toilet, and ensures safety and comfort in use. Due to shape matching, it is easier to achieve accurate docking of the upper sewage outlet butt joint 12 and the lower sewage outlet 32 during installation, reducing the difficulty and error rate of installation.
[0066] The bottom surface of the sewage docking portion 3 abuts against the top surface of the connecting plate 11. This contact mode increases the stability of the connection and prevents shaking or loosening caused by an unstable connection.
[0067] Further, the design of matching the shape of the upper sewage butt pipe 12 and the lower sewage outlet 32 reduces the accumulation and blockage of dirt at the interface, ensuring that the dirt can be smoothly discharged from the toilet into the sewage system. Smooth drainage reduces the maintenance requirements caused by blockage, reducing maintenance costs and time.
[0068] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
