[Technical field to which the invention belongs]

 The present invention relates to a drainage basin with a trap.

[0002]

[Prior art]

It is necessary to place a drainage basin at the point where the branch pipe merges with the main pipe, because dust and mud are likely to be clogged. A drainage basin with a trap is a drainage basin located at such a junction. Conventionally, as shown in FIG. 8, a drainage basin (10) with a trap is provided with an upstream receiving port (2) and a main pipeline that should be connected to the upstream side of the main pipeline from the side surface of the drainage basin body (1) that opens upward. The downstream side receiving part (3) to be connected to the downstream side of the drainage basin body (1) between the upstream side receiving part (2) and the downstream side receiving part (3). Receptacle for trap that should be connected to the pipeline

[0003]

[Problems to be solved by the device]

 Therefore, in the conventional drainage basin with a trap (10), as shown in FIG. 9, the drainage tub (10) must be arranged at the position of the straight pipe part (13) avoiding the bent part (12) of the pipe line (11). There is no degree of freedom and it is necessary to prepare a curved rod (14) separately from the drainage rod (10) with a trap in the bent portion (12), and two rods of different types are required. This is because it is necessary to place a basin because dirt, mud, etc. are likely to be caught in the curved part (12). Therefore, there is a problem that a large space is required, the construction is troublesome, and the cost is economically high.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention has an upstream side receiving part (2A) and a downstream side receiving part (3A) to which the main pipe line (11A) is connected from the side surface of the drainage basin body (1A) opening upward. ) And a U-shaped trap (14A) is connected between the drainage basin body (1A) and the branch pipe (14A) between the upstream side inlet (2A) and the downstream side inlet (3A). 5A), and the main conduit groove (8A) extending from the upstream receiving port (2A) to the downstream receiving port (3A) at the bottom of the drainage basin body (1A) draws a curve. , The U-shaped trap (5A) contacts the main conduit groove (8A) through the weir (9A) inside the curve and is extended downward from the bottom of the main body (1A) (trap receiving part ( 4A), and a drainage basin (10A) with a trap is formed on the left and right sides of the weir (9A) with inclined surfaces (9B, 9B) that are inclined toward the weir. . In the above structure, it is desirable that the outer edge of the main conduit groove (8A) is set so as not to protrude outside the drainage basin body (1A), and further the supporting leg from the bottom of the drainage basin body (1A).

[0005]

[Action]

 The drainage basin with trap (10A) of the present invention connects the upstream side and the downstream side of the main pipe (11A) to the upstream side receiving part (2A) and the downstream side receiving part (3A), respectively, and is a U-shaped The branch line (14A) is connected to the trap (5A). The main drainage channel (8A) at the bottom of the drainage basin body (1A) from the upstream side inlet (2A) to the downstream side inlet (3A) is curved at the drainage basin (10A). The U-shaped trap (5A) is in contact with the main conduit groove (8A) inside the curve of the pipe axis of the main conduit groove (8A) and extends downward from the bottom of the main body (1A). Since it is connected to the mouth (4A), the connection position of the U-shaped trap (5A) is in a state of being held in the main conduit groove (8A), and a branch flow is introduced into the drainage basin (10A). The structure for doing this is very compact. Further, if the outer edge of the main conduit groove (8A) is set so as not to extend outside the drainage channel main body (1A), the structure becomes more compact. If the supporting leg (6A) is hung from the bottom of the drainage basin body (1A) and the lower end of the supporting leg (6A) is at the same level as the lowest part of the U-shaped trap (5A), the drainage Masu (10A) can be installed stably on the foundation. In the drainage basin (10A) having such a structure, the water flowing through the main conduit groove (8A) is directed to the outside of the bend of the main conduit groove (8A) by the centrifugal force, and therefore the water from the branch conduit (14A) is discharged. The branch flow flows into the main pipeline (11A) from the U-shaped trap (5A) through the weir (9A) without being interfered with by the main stream flowing in the main pipeline groove (8A). At this time, since there are slopes (9B, 9B) on the left and right of the weir (9A), the branch flow is guided by the slopes (9B, 9B) and overflows the weir (9A) to overflow the main pipe (11A ), It is guided by the slopes (9B, 9B) when it does not interfere with the main flow and overflows the weir (9A), and the flow of the branch flow into the main pipeline (11A) becomes extremely smooth. Further, if the outer edge of the main conduit groove (8 A) is set so as not to extend outside the drainage basin body (1 A), the main conduit groove (8 A) will not have an overhang portion, and Since the water flowing through the main conduit groove (8A) is hardly repelled toward the U-shaped trap (5A) side, the branch flow can be smoothly introduced into the main conduit (11A). Moreover, in this case, the main conduit groove (8A) is wholly exposed at the opening of the drainage basin body (1A), and since there is no overhang as described above, the drainage basin body (1A) ) Inspection and cleaning from the opening is extremely easy.

【Example】

 The present invention will be described with reference to one embodiment shown in FIGS. 1 to 7. The drainage basin (10A) with a trap is provided with a side face of the drainage basin body (1A) that opens upward and an upstream side inlet (2A) and a downstream side. Side outlet part (3A), and the main conduit groove (8A) extending from the upstream side inlet part (2A) to the downstream side inlet part (3A) at the bottom of the drainage basin body (1A). The recess is provided so that the trap is in contact with the main conduit groove (8A) from the bottom of the drainage basin body (1A) between the upstream side receiving section (2A) and the downstream side receiving section (3A). Has a structure in which the U-shaped trap (5A) is rotatably connected to the trap receiving port (4A) and the U-shaped trap (5A) is rotatably connected to the upstream receiving port (2A). The main conduit groove (8A) from the downstream side inlet (3A) to the downstream side inlet (3A) has a curve bent by θ = 90 ° as shown by the dotted line in FIG. 5, and the trap inlet (4A) has the curved line. It is arranged inside. The trap receiving portion (4A) is in contact with the main conduit groove (8A) via a weir (9A), and inclined surfaces (9B, 9B) are formed on both left and right sides of the weir (9A). There is. As is clear from FIGS. 3 and 6, the outer edge of the main conduit groove (8A) is set so as not to extend outside the drainage basin body (1A). In this way, the position of the trap receiving portion (4A) is in a state of being held in contact with the main conduit groove (8A), and the outer edge of the main conduit groove (8A) is the drainage basin body (1A). Since it does not protrude to the outside of), the structure of the drainage basin is extremely compact. Further, a supporting leg (6A, 7A) is hung from the bottom of the drainage basin body (1A) and the bottom of the U-shaped trap (5A) connected to the trap port (4A). The lower end of the supporting leg (6A) and the lower end of the supporting leg (7A), that is, the lowest part of the U-shaped trap (5A) are at the same level.

As shown in FIG. 7, the drainage basin (10A) having the above-mentioned configuration is arranged, for example, in a curved portion of a main pipeline (11A) which is a sewer pipeline, and the drainage basin (2A) of the drainage basin (10A). ) And the downstream side inlet (3 A) are connected to the upstream side and the downstream side of the main pipeline (11 A), respectively. The U-shaped trap (5A) is connected to, for example, a branch pipe (14A) which is a drainage channel from a home kitchen. Since the lower end of the supporting leg (6A) of the main body (1A) of the drainage basin (10A) and the lower end of the supporting leg (7A) of the U-shaped trap (5A) are at the same level, the drainage basin ( 10A) can be stably installed on the foundation, and therefore the installation work and piping work of the drainage basin (10A) will be extremely easy. The drainage (branch flow) from the home kitchen is guided by the U-shaped trap (5A) to the left and right slopes (9B, 9B) of the weir (9A), overflows the weir (9A), and sewer pipe ( Although it flows into the 1A), the U-shaped trap (5A) is water-sealed by the drainage so that the odor from the sewer pipeline (11A) does not enter the branch pipeline (14A) side. There is. Then, the water (mainstream) flowing through the sewer pipe (11A) is directed to the outside of the bend of the main pipe groove (8A) of the drainage pipe (10A) by centrifugal force at the location of the drainage pipe (10A), and Since the outer edge of the groove (8A) does not protrude to the outside of the drainage basin body (1A), there is no overhang portion in the main conduit groove (8A), as is apparent from FIG. As shown by arrow a, the water oriented outside the bend of the main conduit groove (8A) hardly bounces to the U-shaped trap (5A) side, and therefore the branch from the branch conduit (14A). In the drainage basin body (1A), the flow smoothly flows into the drainage basin (10A) without being interfered with by the mainstream of the main pipeline groove (8A) forming a part of the sewer pipeline (11A).

The main conduit groove (8A) of the drainage basin (10A) is wholly exposed at the opening of the drainage basin body (1A), and since there is no overhang portion as described above, the drainage basin body Inspection and cleaning from the opening of (1A) is extremely easy.

In the present invention, the bending angle θ of the main conduit extending from the upstream receiving portion to the downstream receiving portion may be set to other than 90 °, for example, 120 °, 135 ° or the like.

[0010]

[Effect of the invention]

 As described above, in the present invention, since the drainage basin with a trap can be arranged in the curved portion of the main pipeline and the branch flow can be merged at this position, the flexibility of the piping is large and only one basin is required. It saves costly materials, and can be processed at half the economic cost and in half the space. Since the U-shaped trap for introducing the upper branch flow is connected to the inside of the main conduit groove at the bottom of the drainage basin, the structure is extremely compact and piping work becomes easy. Therefore, the labor required for construction is greatly improved, and the branch flow introduced into the main flow of the main pipeline from the branch pipeline through the U-shaped trap does not stagnate or flow backward at the drainage basin, and the slopes on the left and right of the weir. Guided by, and flowed smoothly into the main pipeline via the Tsue weir. It is also extremely easy to inspect and clean the inside of the drainage basin.
