Description
Technical Field
[0001] The invention relates to the technical field of same-floor drainage of building toilets, and in particular to a same-floor drainage system with a flat-tube rear-mounted water collector and a non-dropping plate. Background Art
[0002] The existing same-floor drainage systems are divided into three categories: full-drop plate, partial-drop plate and non-drop plate same-floor drainage systems. The thickness of the drop plate in the full-drop plate and partial-drop plate same-floor drainage systems is 250-400mm, and the main problems are that the thickness of the drop plate is too large, the use of bonding on the pipes leads to easy water accumulation in the caisson, and the project cost is not economical; the thickness of the drop plate in the non-drop plate same-floor drainage system is 150-250mm, and the main problems are that on the one hand, the sewage riser access pipe fittings are pre-buried in the floor slab, which requires a large hole and cannot be effectively sealed, resulting in failure to meet relevant fire protection regulations when a fire occurs between the upper and lower floors, and the branch pipes need to cooperate with secondary decoration treatment. On the other hand, the water seal of the ordinary floor drain is easily blocked, causing water seepage or backflow, and the ground needs to be destroyed for maintenance when the system is blocked. Therefore, the technical solution of the present invention is aimed at solving the above-mentioned problems. Summary of the invention
[0003] In view of the above-mentioned problems, the present invention aims to provide a flat-tube post-type water collector and non-lowering same-floor drainage system, including a bathroom main body and a floor, a floor drain without a water seal is arranged on the ground, and the water seal of the floor drain is uniformly replaced by a post-type water collector, thereby reducing the height of the floor drain and the overall height of the pipeline.
[0004] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present invention is as follows: a flat tube rear-mounted water collector non-lowering same-floor drainage system, including a bathroom main body and a floor, wherein the interior of the bathroom main body is provided with a rear-drainage toilet, a shower room, a washbasin, a bidet and a door clockwise along the floor, and a sewage riser is arranged between the rear-drainage toilet and the shower room, characterized in that: the drainage system includes a flat tube assembly, the rear-drainage toilet is connected to the sewage riser via a concealed sewage pipe along the wall above the ground, a floor drain is arranged on the floor between the shower room and the washbasin and bidet, the floor drain, washbasin and bidet are all connected to the sewage riser via the flat tube assembly, and a rear-mounted water collector is arranged at one end of the flat tube assembly close to the sewage riser.
[0005] Preferably, the flat tube assembly includes a flat straight tube, a flat 45° oblique tee, a flat 90° conversion elbow, and a flat 45° elbow.
[0006] Preferably, a plurality of flat straight pipes are arranged inside the shower room, washbasin and bidet to be connected to the wastewater main pipe and connected to the sewage riser; the floor drain and washbasin are connected to the wastewater main pipe through a flat 90° conversion elbow, a flat straight pipe, a flat 45° elbow and a flat 45° inclined tee in sequence; the bidet is connected to the wastewater main pipe through a flat 90° conversion elbow, a flat straight pipe and a flat 45° elbow in sequence; one side of the rear-mounted water collector is connected to the flat straight pipe, and the other side thereof is connected to the sewage riser through a flat 45° elbow.
[0007] Preferably, a drainage grate is arranged on the floor drain, and the drainage grate comprises a first-stage grate and a second-stage grate which are arranged in sequence from top to bottom.
[0008] Preferably, the post-type water collector and the flat tube assembly both use electrofusion pipe fittings.
[0009] Preferably, the sewage pipe and the wastewater main pipe are both arranged at an inclination.
[0010] The beneficial effects of the present invention are as follows: (1) the flat tube assembly replaces the traditional circular drainage pipe to reduce the height of the wastewater main pipe. After adding the height difference caused by the inclined setting of the wastewater main pipe, the total height does not exceed the normal floor drop height in the drainage of different floors of residential buildings, apartments, etc. with heating, that is, there is no need to additionally lower the floor elevation. Under the premise of meeting the normal drainage capacity, the height occupied by the drainage system is only 120-150mm, which is the minimum height occupied by the current same-floor drainage system. (2) The floor drain is provided with a two-stage drainage grate to effectively avoid debris clogging the pipe; a flat tube is provided at the water outlet to reduce the height occupied by the floor drain. (3) The toilet adopts a rear drainage method, which is concealed above the ground along the wall and connected to the sewage riser. All drainage from all appliances except the toilet flows through the rear-mounted water collector and then connects to the sewage riser. (4) The rear-mounted water collector has a removable cleaning port. It is usually sealed to extend the natural evaporation time of the water seal by several times. During maintenance, the top cover can be opened to clear debris, avoiding the need to damage the ground for maintenance when the system is blocked. A flat 45° elbow is set at the water outlet to improve the hydraulic conditions of branch pipe drainage and reduce the damage to the water seal caused by backflow or air pressure fluctuations. (5) The flat 90° conversion elbow with a grate is connected to all branch pipes, which can eliminate the phenomenon of water leakage or backflow caused by the rear-mounted water collector at the end. The drainage grate is flush with the top surface of the flat tube, which can fully reduce the height occupied by the system. Compared with the traditional floor drain, the 90-degree flat tube conversion elbow with a grate has a higher water level in front of the water seal, and the hydraulic conditions for ground drainage are better, which can eliminate the phenomenon of water accumulation due to untimely ground drainage of traditional floor drains.

[0016] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0017] See attached Figure 1-5 The flat tube rear-mounted water collector non-drop floor same-floor drainage system shown in the figure comprises a toilet body a and a floor b, wherein a rear-drainage toilet seat c, a shower room d, a washbasin e, a bidet f and a door g are installed clockwise along the floor b inside the toilet body a, a sewage riser 1 is arranged between the rear-drainage toilet seat c and the shower room d, and the drainage system comprises a flat tube assembly, wherein the rear-drainage toilet seat c is connected to the sewage riser 1 through a concealed sewage pipe 3 along the wall above the floor b, and the shower room d and the washbasin e and the bidet f are all arranged on the floor b between A floor drain 4 is provided, and the floor drain 4, washbasin e and bidet f are all connected to the sewage riser 1 through a flat tube assembly. A rear-mounted water collector 2 is provided at one end of the flat tube assembly close to the sewage riser 1. After the rear-mounted water collector 2 replaces the water seal of the ordinary floor drain, the ordinary floor drain is set as a floor drain 4 without a water seal, which further reduces the height of the pipeline. On the other hand, a rear-mounted water collector is provided for the entire pipeline, which also reduces the maintenance work of multiple ordinary floor drains. Compared with the water seal of multiple ordinary floor drains, the water seal has a larger pipe diameter, the drainage speed is higher, and the blockage failure is lower.
[0018] Furthermore, the flat tube assembly includes a flat straight tube 5, a flat 45° inclined tee 6, a flat 90° conversion elbow 7, and a flat 45° elbow 8. Through the various types of the above flat tube assemblies, suitable flat tubes can be selected according to the actual layout of the bathroom. The advantages are that the matching is convenient and the height of the pipeline can be reduced.
[0019] Furthermore, a plurality of flat straight pipes 5 are arranged inside the shower room d, washbasin e and bidet f to connect to the wastewater main pipe and connect to the sewage riser 1, and the remaining branch pipes are connected to the wastewater main pipe. The floor drain 4 and washbasin e are connected to the wastewater main pipe through the flat 90° conversion elbow 7, the flat straight pipe 5, the flat 45° elbow 8 and the flat 45° inclined tee 6 in sequence; the bidet f is connected to the wastewater main pipe through the flat 90° conversion elbow 7, the flat straight pipe 5 and the flat 45° elbow 8 in sequence, one side of the rear-mounted water collector 2 is connected to the flat straight pipe 5, and the other side thereof is connected to the sewage riser 1 through the flat 45° elbow 8. The above branch pipe connection method is the preferred combination, and the connection method can be flexible and changeable.
[0020] The above-mentioned drainage system is laid in a manner of diverting the sewage pipe 3 from the wastewater main pipe, thereby effectively realizing the separation of drainage in the bathroom a, and connecting to the sewage riser 1 from different heights, effectively achieving the effect of drainage and sewage discharge; and using the flat tube structure of the pipe to reduce the height occupied by the overall drainage branch pipe, thereby effectively avoiding the problem of needing to additionally lower the floor height.
[0021] Furthermore, a drainage grate 9 is arranged on the flat 90° conversion elbow 7, and all the flat 90° conversion elbows 7 with the drainage grate 9 are connected by branch pipes, which can eliminate the phenomenon of water leakage or backflow caused by the rear-mounted water collector 2 arranged at the end; the drainage grate 9 is flush with the top surface of the flat tube, which can fully reduce the height occupied by the system. Compared with the traditional floor drain drainage, the flat 90° conversion elbow 7 with the drainage grate 9 has a higher water level before the water seal, and the hydraulic condition of the ground drainage is better, which can eliminate the phenomenon of water accumulation due to the traditional floor drain 4 not draining in time.
[0022] Furthermore, the post-type water collector 2 and the flat tube assembly both use electric fusion pipe fittings. When in use, the electric fuse is used to pass current through the corresponding pipe fittings. The current generates temperature through the corresponding pipe fittings and melts the pipe fittings, thereby completing the connection between the various pipe fittings. The electric fusion pipe fittings have the advantages of good sealing and the connection is not easy to loosen.
[0023] In order to further increase the water flow rate of the sewage pipe 3 and the wastewater main pipe, the sewage pipe 3 and the wastewater main pipe are both inclined. After the inclination, the total height of the pipe does not exceed the normal floor drop height in the different-layer drainage of residential buildings, apartments and other buildings with heating, that is, there is no need to additionally lower the floor elevation. Under the premise of meeting the normal drainage capacity, the height occupied by the drainage system is the minimum technical solution for the current same-layer drainage system.
[0024] In order to ensure a wider range of system applications, a larger bathroom was selected to study various most unfavorable situations. The following is an explanation of the drainage capacity of the flat tube rear-mounted water collector non-dropping same-floor drainage system through actual experimental data: This test platform was built at a 1:1 ratio, and the bathroom size was 3.7×1.8m. Three tests were conducted, respectively, using a measuring cylinder with a range of 5L and a minimum scale of 0.01L to test the drainage volume of the sanitary ware, and a stopwatch was used to time it, accurate to 0.01s. Each group of experiments was tested for 30s after the water flow stabilized, and five parallel experiments were conducted in all three tests:
[0025] ①Open the wash basin e and test the data as follows:
[0026]
[0027] ② Open the wash basin e and shower room d at the same time and test the data as follows:
[0028]
[0029] ③ Open the wash basin e, shower room d and bidet f at the same time and test the data as follows:
[0030]
[0031] According to the above experimental data, the average values of five parallel experimental data, namely, opening wash basin e, opening wash basin e and shower room d at the same time, and opening wash basin e, shower room d and bidet f at the same time, were 0.276L / s, 0.349L / s, and 0.564L / s respectively. During the three tests in the most unfavorable super-large bathroom, no adverse phenomena such as backflow occurred in the water-free floor drain, which met the requirements of the specification, so it has better drainage performance in conventional bathrooms.
[0032] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
