Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a drainage basin, and particularly to a drainage basin that is convenient when connecting a new drainage pipe to an existing drainage pipe.

(Prior art) Conventionally, when it became necessary to connect a new drain pipe to an existing drain line, it was installed on the top of an appropriate straight drain A or curved drain, as shown in Figure 7. The connecting end of a new drain pipe C was passed through the circumferential wall of the adjusting cylinder B, and an elbow D was fitted upward at its tip to provide a trap function. Another method is to provide a U-shaped pipe section E in the middle of the drain pipe C instead of arranging the elbow D inside the adjustment tube B, as shown by the imaginary line in FIG.

(Problem that the invention seeks to solve) However, if the elbow D is fitted to the tip of the drain pipe C, as is clear from the figure, the elbow D will get in the way, making it difficult to clean or inspect the drain A. There was a problem. In addition, if a U-shaped pipe part E is provided in the middle of the drain pipe C, a horizontal drain pipe is interposed between the inside of the adjustment cylinder B and the U-shaped pipe part E, so the drain pipe C
There was a problem that it was difficult to clean.

Therefore, an object of the present invention is to provide a drainage basin to which a new drainage pipe can be connected in a state where cleaning and inspection can be easily performed.

(Means for Solving the Problems) In order to achieve this objective, the present invention forms a gutter-like drainage passage at the bottom of the cell main body, and connects the side wall and the peripheral wall of the cell main body with a continuous wall. To provide a drainage basin in which the drainage passage is arranged so that a region large enough to connect a drainage pipe substantially vertically is formed in a part of the continuous wall.

(Function) According to the drainage basin having such a configuration, when it becomes necessary to connect a new drain pipe, a hole with approximately the same diameter as the drain pipe is made in the area of the continuous wall where the drain pipe can be connected, and the drain pipe is connected. The connection can be made by passing through the tip of the U-shaped tube or L-shaped tube formed at the tip of the pipe, and since the inside of the drain basin is completely open, cleaning and inspection of the drain passage is easy and trap-free. U with function
Cleaning of the tube portion and the L-shaped tube portion can be easily performed since the upper end thereof is open.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 3. Reference numeral 1 denotes a drainage basin called a "straight basin" in which a gutter-like drainage passage 3 is formed in a straight line at the bottom of a basin main body 2 having a circular planar shape.
and are connected by a continuous wall 5 having a curved surface.
Both ends of the drainage passage 3 communicate with connection cylinders 6a and 6b integrally formed to protrude from the bottom of the main body 2. A receiving flange 7 having an L-shaped cross section is formed on the outer periphery of the upper end of the peripheral wall 4, and the lower end of the adjustment tube 9 is fitted into a groove 8 formed between the receiving flange 7 and the upper end of the peripheral wall 4. It is arranged like this.

Unlike a conventional straight cell, the drain passage 3 is formed eccentrically to one side without passing through the center of the cell main body 2, and is connected to a part of the continuous wall 5 by a disconnection of the drain pipe. A region 10 is formed which is larger than the area and has a size that allows a drain pipe to be connected substantially vertically. The diameter of a pipe normally used as a drain pipe is 40 to 100 mm, and the width of this region 10 may be equal to or larger than the pipe diameter. In this area 10,
The continuous wall 5 is formed into a flat wall 11 that is substantially horizontal and slightly inclined toward the drainage passage 3.

If the drainage basin 1 with the above configuration is installed in the existing drainage pipe, if it becomes necessary to install a new drainage pipe 12 and connect it to the drainage pipe later due to renovation or expansion, As shown in FIG. 3, a hole 13 having approximately the same diameter as the drain pipe 12 is drilled in the flat wall 11 of the drainage basin 1 using a hole saw, one end of the U-shaped pipe 14 is passed through this hole 13, and an adhesive or If the U-shaped tube 14 is sealed and connected with the sealing material 15 and the other end of the U-shaped tube 14 and the tip of the drain pipe 12 are connected via the elbow 16, the U-shaped tube 14
The drain pipe 12 can be connected to the drain basin 1, that is, to the existing drain pipe line, with a trap consisting of a trap. Moreover, since there is no obstruction protruding inside the drain basin 1, the drain passage 3 is connected to the drain pipe 1.
2 can be easily inspected and cleaned in the same way as before connection, and the U-shaped pipe 14, which is a trap for the drain pipe 12, has one end opening upward into the drain basin 1, so it can be easily cleaned. can.

Incidentally, instead of the U-shaped tube 15, an L-shaped tube such as an elbow can be fitted onto the tip of the drain pipe 12, and its upper end can be connected to the hole 13 to serve as a trap.

In the above embodiment, the hole 13 is drilled in the plane wall 11 with a hole saw, but as shown in FIG. A circular V-shaped groove 17 is formed in advance, and when the drain pipe 12 is connected, the V-shaped groove 17 is struck with a hammer or the like.
It is also possible to make the holes 13 along the lines.

Further, in the above embodiment, the continuous wall 5 is formed with a substantially horizontal plane wall 11, but as shown in FIG. The continuous wall 5 has a circular shape with a diameter D corresponding to the diameter of the hole to be drilled.
A groove 18 may also be formed.

In addition, the drainage passage 3 is not limited to a straight-walled drainage basin 21, which has a straight-walled drainage passage 3, but also a drainage basin 21 called a ``curved'' drainage passage 21, which has an arc-shaped drainage passage 23, as shown in Fig. 6. By forming the area 23 with its position shifted toward the outer circumferential side, it is possible to form the area 22 on the center side of the curvature, which has a width that allows a drain pipe to be connected substantially vertically.

(Effects of the invention) As is clear from the above explanation, the drainage basin of the invention has a width that allows the drain pipe to be connected approximately perpendicularly to the continuous wall that connects the peripheral wall of the basin body and the side wall of the drainage passage. If you need to connect a drain pipe later, you can connect the drain pipe from the bottom of the drain basin by drilling a connection hole for the drain pipe in this area. By connecting the drain pipe, cleaning and inspection of the drain passage will not become difficult, and by connecting the upper end of the trap provided at the tip of the drain pipe to this connection hole. The trap section can also be easily cleaned from above.
