Description

Technical Field

[0001] The invention relates to the technical field of same-floor drainage in building toilets, and in particular to a flat-tube front-floor drain type non-dropping plate same-floor drainage system. Background Art

[0002] The existing same-floor drainage systems are divided into three categories: full drop-down, partial drop-down and non-drop-down same-floor drainage systems. The thickness of the drop-down for the full drop-down and partial drop-down same-floor drainage systems is 250-400mm. The main problems are that the thickness of the drop-down is too large, the pipes are bonded, which makes it easy for water to accumulate in the caisson, and the project cost is not economical; the thickness of the drop-down for the non-drop-down same-floor drainage system is 150-250mm. The main problem is that the sewage riser access pipe fittings are pre-buried in the floor slab, which requires a large opening and cannot be effectively blocked, resulting in the failure to meet the relevant fire protection regulations when a fire occurs between the upper and lower floors, and the branch pipes need to cooperate with secondary decoration. Therefore, the technical solution of the present invention is to solve 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 front floor drain type non-dropping same-floor drainage system, including a bathroom main body and a floor. By arranging a front floor drain and a flat tube assembly, the problems of requiring a larger hole when pre-buried floor slabs and fire prevention between upper and lower layers are solved, and the height of the drop plate is also greatly reduced.

[0004] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present invention is as follows: a flat-tube front floor drain type non-dropping same-floor drainage system, including a bathroom main body and a floor, the interior of the bathroom main body is equipped with a rear-drainage toilet, a shower room, a washbasin, a bidet and a door clockwise along the floor, a sewage riser is arranged between the rear-drainage toilet and the shower room, and is characterized in that: the drainage system includes a flat tube assembly, a flat tube swirl tee is sleeved on the sewage riser, the rear-drainage toilet is connected to the flat tube swirl tee through a concealed sewage pipe along the wall above the ground, a front-type floor drain is arranged on the floor between the shower room and the washbasin and bidet, and the front-type floor drain, washbasin and bidet are all connected to the flat tube swirl tee through the flat tube assembly.

[0005] Preferably, the flat tube assembly includes a flat straight tube, a flat 45° oblique tee, a flat 90° conversion elbow, a flat 45° elbow, and a 90° flat 90° conversion elbow.

[0014] 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.

[0015] See attached Figure 1-3 The flat tube front floor drain type non-dropping same-floor drainage system shown in the figure comprises a toilet body a and a floor b, wherein a rear drainage toilet 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 c and the shower room d, the drainage system comprises a flat tube assembly, a flat tube swirl tee 2 is sleeved on the sewage riser 1, the rear drainage toilet c is connected to the flat tube swirl tee 2 by a concealed sewage pipe 3 along the wall above the floor b, a front type floor drain 4 is arranged on the floor b between the shower room d and the washbasin e and the bidet f, the front type floor drain 4, the washbasin e and The bidet f is connected to the flat tube swirl tee 2 through a flat tube assembly; the flat tube swirl tee 2 can not only speed up the discharge of sewage and is not easy to block the pipe, but also reduce the height of the pipe. The flat tube swirl tee 2 can make the sewage and wastewater flow rotate on the one hand. Under the action of centrifugal force, the water flow rotates downward along the wall of the vertical pipe, and the space in the middle can discharge the gas, so that the sewage riser 1 will not cause blockage, reducing the maintenance of the drainage riser 1 and improving the project quality; on the other hand, the flat tube design does not require local openings on the floor slab, and will not affect the fire protection between the upper and lower floors, greatly reducing the height of the pipe and increasing the height of the bathroom.

[0016] Furthermore, the flat tube assembly includes a flat straight tube 5, a flat 45° oblique tee 6, a flat 15° conversion elbow 7, a flat 45° elbow 8, and a 90° flat 90° conversion elbow. 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.

[0017] 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 flat tube swirl tee 2, and the remaining branch pipes are connected to the wastewater main pipe. The front floor drain 4 is connected to the wastewater main pipe via the flat 15° conversion elbow 7, the flat straight pipe 5, the flat 45° elbow 8 and the flat 45° inclined tee 6 in sequence; the washbasin e is connected to the wastewater main pipe via the flat 90° conversion elbow, 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 via the flat 90° conversion elbow, the flat straight pipe 5 and the flat 45° elbow 8 in sequence. The above branch pipe connection method is a preferred combination, and the connection method can be flexible and changeable.

[0018] Furthermore, a drainage grate 9 is arranged on the front floor drain 4, and the drainage grate 9 includes a first-stage grate 91 and a second-stage grate 92 arranged in sequence from top to bottom, wherein the first-stage grate 91 has a coarser filter mesh and can filter out large dirt, and the second-stage grate 92 has a finer filter mesh and can filter out smaller dirt. The two-stage grate solves the problem that the first-stage grate cannot filter out dirt in time, causing grate blockage and affecting drainage.

[0019] Furthermore, the flat tube swirl tee 2 and the flat tube assembly both use electric fusion pipe fittings. When in use, an 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.

[0020] 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 only 120-150mm, which is the technical solution with the smallest height occupied by the same-layer drainage system.

[0021] 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 front floor drain type non-dropping same-floor drainage system through actual experimental data: This test platform was built in 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:

[0022] ①Open the wash basin e and test the data as follows:

[0023]

[0024] ② Open the wash basin e and shower room d at the same time and test the data as follows:

[0025]

[0026]

[0027] ③ Open the wash basin e, shower room d and bidet f at the same time and test the data as follows:

[0028]

[0029] According to the above experimental data, the average values ​​of five parallel experimental data were 0.249L / s, 0.380L / s, and 0.523L / s respectively when wash basin e was turned on, wash basin e and shower room d were turned on at the same time, and wash basin e, shower room d, and bidet f were turned on at the same time. During the three tests, there was no backflow or other drainage problems in the water seal front type floor drain, which met the requirements of the specification.

[0030] In the present invention, except for the sewage pipe 3, all other pipes are composed of flat pipe fittings. The flat pipe fittings reduce the height occupied by the overall wastewater pipe, thereby effectively avoiding the problem of needing to additionally lower the floor height on the basis of the normal lowering of the floor for different-layer drainage in traditional bathrooms, and completely replacing the existing different-layer drainage system, achieving the beneficial effect of same-layer maintenance and no holes in the floor.

[0031] 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. 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. The scope of protection of the present invention is defined by the attached claims and their equivalents.
