Description

[Detailed description of the invention] The present invention relates to a drainage basin installed in the middle of a drainage pipe, and in particular, the inlet and the outlet are located on the same axis, and the drainage basin flowing from the inlet is directly disposed of. Regarding the straight drainage basin that drains from the outlet.

In conventional straight drainage basins, the inlet, drainage passage, and outlet are arranged in a straight line along the diametrical centerline passing through the center of the basin body, and the drainage is symmetrical with respect to the centerline. It has the advantage that it can be applied to drainage pipes in either the left or right flow direction even if the passage has a slope. However, as shown in Figure 1, in the curved drainage basin 2, drainage basin with trap 3, combined drainage basin 4, etc. installed in the drainage pipe line 1, the inlet and flow are limited due to functional and structural limitations. The outlet is arranged on the axis eccentric to the center line of the main body, and when the straight drainage basin 5 is interposed in the drain pipe 1 together with the bent drainage basin 2, the trap-equipped drainage basin 3, etc., the drainage The cells are not arranged in a straight line but are arranged in a zigzag pattern, making the installation work complicated and creating an unsightly appearance.

In view of such conventional problems, the object of the present invention is to provide a straight drainage basin in which the drainage basins are arranged in a straight line even when installed in a drain pipe along with other types of drainage basins.

Therefore, the present invention forms an inlet and an outlet on the outside of the main body, which are located on an axis eccentric to the diametrical center line passing through the center of the main body, and these inlets are inside the main body. A drain passage is formed connecting the inlet and the outlet to provide an eccentric straight drain similar to other types of drains.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 6. In the straight drainage basin 10a shown in Fig. 2, reference numeral 6 denotes a basin body made of low-foaming synthetic resin that is circular in plan view, and extends along an axis P eccentric to the diametrical center line passing through the center O. A groove-shaped drainage passage 7 is formed in the drain passage 6, and an inlet 8 and an outlet 9, which are located on the axis P and communicate with the drainage passage 7, are protruded from both sides of the peripheral wall of the main body. The drainage passage 7 has a downward slope in the direction of the arrow in the figure from the inlet 8 to the outlet 9, and is configured so that the drainage flows in the direction of the arrow. In addition, the amount of eccentricity of the axis P with respect to the center O is:
As with other types of drainage basins, the radius is set to be approximately the same as the inlet 8 and outlet 9, and the drainage passage 7
One side wall of the square body 6 passes near the center of the square body 6.

The straight drainage basin 10b shown in Figure 3 is the second
It is on the opposite side from the figure, and the axis P' of the drainage passage 7, inlet 8, and outlet 9 is eccentric to the opposite side from the center O of the cell main body 6 than in the case of Fig. 2. . In other words, in Fig. 2, it is eccentric to the left as it faces downward in the flow direction of the wastewater, whereas the third
In the figure, it is eccentric to the right side, and either FIG. 2 or FIG. 3 is selected and used depending on the flow direction of the drain pipe 1.

In the case of such an embodiment, two types of straight drainage basins 10 with opposite sides are used as shown in Figs. 2 and 3.
It is necessary to prepare a and 10b. Therefore,
One type of drainage basin can be applied to any flow direction, and as shown in Fig. are located to form inlets 8a, 8b and outlets 9a, 9b, respectively, and these inlets 8a,
8b and the outflow ports 9a and 9b are connected to a substantially X-shaped drainage passage 1.
1 communicates with the unused inlet 8a or 8
A straight drainage basin 1 in which the outlet port 9a or 9b is closed with a stopper 12 as shown in Fig. 5.
3 can also be used. The plug body 12 is made of a hollow body formed by blow molding or the like, and is configured so that it can be fitted into the inlet or the outlet from the outside, and has a fitting part 1 into the drainage passage 11 at its tip.
2a is formed and is configured to close off an unnecessary portion of the drainage passage 11. That is, when using the inlet 8a and the outlet 9a, for example, the plug 12 is fitted into the inlet 8b and the outlet 9b as shown by imaginary lines in FIG. The inlet 8 is closed by closing the part that branches toward the inlet 8b and the outlet 9b.
A smoothly curved drainage passage is formed from a to the outlet 9a, so that the drainage can flow without stagnation as shown by the arrow.

In addition, by making the straight drainage basin 13 in Fig. 4 have an X-shaped drainage passage 11,
No matter which inlet or outlet is used, the central part of the drainage passage 11 is shared.
Like the straight drainage basin 15 shown in the figure, separate drainage passages 14a, 14b are provided between each inlet 8a, 8b and outlet 9a, 9b, and the shape is a combination of the straight drainage basins shown in Figures 2 and 3. You can also use it as

As is clear from the above explanation, the straight drainage inlet of this device has an inlet and an outlet arranged on an axis that is eccentric to the centerline in the diameter direction that passes through the center of the drainage inlet body, and these are connected by a drainage passage, so even if it is installed in a drainage pipe together with a curved drainage inlet, a drainage inlet with a trap, or a combined drainage inlet,
The drains are not arranged in a zigzag pattern but in a straight line, making installation easy and improving the appearance.
