Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain trap attached to a drain port of a bathtub or the like.

[0002]

2. Description of the Related Art In a drain trap, a water reservoir is formed in the middle of a drainage system. By blocking the flow of air in a drain pipe by the water reservoir, a backflow of odor from downstream is prevented. It is something to do.

[0003] In the construction of a new house or the like, the construction date of the bathtub and the construction of the drainage system are generally different from each other in terms of the construction date and the contractor. In such a case, the drainage contractor often attaches the drainage trap to the bathtub drainage system without confirming that the drainage trap has already been installed at the drain of the bathtub by the bathtub installer. Occurs. As described above, in the state of a so-called double trap in which two drain traps are attached to the same drain system, the resistance of the drain is received at two places, and the flow of the drain is deteriorated.

In order to eliminate the double trap, one of the drain traps is released. Conventionally, as a drain trap capable of releasing a trap after construction, for example, an overflow partition plate provided for partitioning a water reservoir is formed so as to be breakable, and this partition plate is broken. Is known to release the trap.

[0005]

However, since the conventional drain trap has a structure in which the partition plate is broken, it is necessary to insert a rod-shaped tool from the drain port into a narrow space inside the drain trap. At this time, work must be performed while paying attention not to damage the periphery and the inside of the drain port, so that workability is poor. In addition, there is a problem that broken pieces of the partition plate remain inside and this obstructs drainage.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. When the trap is released after construction, a drain trap which does not cause any damage or debris remains with a simple operation. The task is to provide.

[0007]

In order to solve the above-mentioned problems, a drain trap according to the present invention is divided into a water reservoir and an overflow receiver by an overflow partition plate, and the water trap is located above the water reservoir. A trap body having an attachment opening formed therein and an overflow receiving portion communicating with the outlet, and an upper edge of the partition plate which is detachably attached to the attachment opening and whose lower end is immersed in the water reservoir. A drainage introduction pipe which is located below and opened, and a cut mark is displayed on the drainage introduction pipe at a position above the upper edge of the partition plate.

In this case, there is a mode in which the cutting mark is formed by a thin annular groove formed by reducing the thickness of the drainage introduction pipe.

In the drain trap of the present invention, the drain trap is installed in a state where the drain introduction pipe is attached to the attachment opening of the trap body. Therefore, the sewage from the drainage introduction pipe flows into the water reservoir of the trap body, flows into the overflow receiving portion beyond the upper edge of the partition plate, and is drained from the overflow receiving portion via the outlet. At this time, since the lower end of the drainage introduction pipe is located below the upper edge of the partition plate so as to be immersed in the water sump, and is open, the drainage introduction pipe upstream of the water sump and downstream of the water sump. The air flow is shut off between the overflow receiver and the airflow receiver. Thereby, the backflow of the odor from the downstream can be prevented.

[0010] The drainage introduction pipe is detachably attached to the mounting opening of the trap body, and a mark for cutting is displayed on the drainage introduction pipe. Therefore, in order to release the trap, the drainage introduction pipe is removed from the attachment opening of the trap body, and then the drainage introduction pipe is cut from the cutting mark with a cutter or the like, and then the drainage introduction pipe is again attached to the trap body attachment opening. Will be attached to. Since the cutting mark is displayed above the upper edge of the partition plate, the cut opening of the drainage introduction pipe opens above the water surface of the water reservoir. As a result, a space is created between the cutout of the drainage introduction pipe and the water surface of the water reservoir, and since this space eliminates the resistance of the water drainage by the water reservoir, the trap can be released.

[0011] Since the above-mentioned cutting operation of the drainage introduction pipe is performed in a state of being detached from the trap body and along the cutting mark, the operation is facilitated.
Therefore, the operation is simplified, and the trap body is not damaged or debris remains.

When the cutting mark is formed by a thin annular groove, the cutting can be easily performed, and the thin annular groove guides the direction of a cutter or the like, so that the cut surface is finely finished. be able to.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a drain trap according to the present invention, and FIG. 2 is a sectional view of the drain trap in a state where the trap is released.

In the figure, reference numeral 1 denotes a trap body, and ABS
It is formed in a box shape by resin or hard vinyl chloride resin. The inside of the trap body 1 is provided with a water reservoir 11 and an overflow receiver 1 by an overflow partition plate 10.
2, a mounting port 13 is formed above the water reservoir 11, and an overflow receiver 12 is communicated with an outlet 14. A mounting guide tube 13a is vertically provided at the mounting opening 13 so as to face the water reservoir 11, and a female screw 13b is formed on the inner periphery of the mounting guide tube 13a.

Next, reference numeral 2 denotes a drainage introduction pipe, which is detachably attached to the attachment port 13 of the trap body 1 and in which the lower end port 20 of the drainage introduction pipe 2 is immersed in the water reservoir 11. The partition plate 10 is open below the upper edge 10a. In the drainage introduction pipe 2, a thin annular groove 21 as a cutting mark is formed at a position above the upper edge of the partition plate 10 by making the thickness of the drainage introduction pipe 2 thin.

A flange 22 is formed at the upper end of the drainage introduction pipe 2, and a male screw 23 is formed on the outer periphery above the thin annular groove 21.

In this embodiment, a case where a drain trap is attached to the drain port 30 of the bathtub 3 is shown. In this case, the drain port 30 formed in the bottom wall 31 of the bathtub 3
Then, the trap main body 1
Is fixed to the back surface of the bottom wall 31 of the bathtub 3 with an adhesive 4. Then, the mounting guide tube 1 is passed through the drain port 30.
The drainage introduction pipe 2 is inserted into the 3a from above, and the male screw 23 is screwed into the female screw 13b. Thereby, the drainage introduction pipe 2 is detachably attached to the attachment port 13. In the drawing, reference numeral 5 denotes a packing, and 6 denotes a drain pipe.

In the drain trap mounted as described above, the sewage in the bathtub 3 flows into the water reservoir 11 of the trap body 1 by the drainage introduction pipe 2, and then the upper edge 10a of the partition plate 10 is removed. Then, the water flows into the overflow receiving portion 12 and is drained from the overflow receiving portion 12 through the water distribution pipe 6 attached to the outlet 14. At this time, the partition plate 10 is set so that the lower end 20 of the drainage introduction pipe 2 is immersed in the water reservoir 11.
Because it is located below the upper edge 10a and is open,
A drainage introduction pipe 2 upstream of the water reservoir 11 and a water reservoir 1
The flow of air is interrupted by the water W accumulated in the water reservoir 11 between the overflow receiver 12 and the overflow receiver 12 downstream of 1. This allows the trap to perform its original function of preventing the backflow of odor from downstream.

Further, in order to eliminate the double trap caused by an error in construction, the male screw 23 is loosened and the drainage introduction pipe 2 is removed from the mounting opening 13 of the trap body 1.
Next, the drainage introduction pipe 2 is cut from the thin annular groove 21 serving as a cutting mark by a cutter or the like, and then the drainage introduction pipe 2 is attached to the attachment opening 13 of the trap body 1 again. The thin annular groove 21 is provided in the partition plate 10.
Is formed at a position higher than the upper edge 10 a of the drainage pipe 2,
Open above. Thereby, drainage introduction pipe 2
Space S between the cut opening 20a of the
Is generated, and the resistance of drainage by the water reservoir 11 is eliminated by the space S, so that the trap can be released.

As described above, the above-described drainage introduction pipe 2
The cutting work is performed with the body removed from the trap body 1.
In addition, since the operation is performed along the thin annular groove 21, the work becomes easy. Therefore, the operation is simplified, and the trap main body 1 is not damaged or debris remains.
Further, since the thin annular groove 21 guides the direction of the cutter or the like, the cut surface can be finely finished.

Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration of the present invention is not limited thereto. For example, the drain trap of the present invention can be attached to a drain port of a kitchen sink, a wash basin, or the like, in addition to the bathtub.

Also, the cut mark of the drainage introduction pipe is not limited to the thin annular groove, and a cutout line may be drawn on the outer peripheral surface of the drainage introduction pipe by printing or the like.

[0023]

As described above, in the drain trap of the present invention, since the lower end of the drain introduction pipe is located below the upper edge of the partition plate and is open, the water trap section is formed. The flow of air is blocked by the water accumulated in the trap, whereby the original function of the trap for preventing the backflow of odor from downstream can be achieved.

Further, in order to release the trap, the drainage introduction pipe may be removed from the mounting opening of the trap body, and cut off from a cutting mark with a cutter or the like. As described above, the work of cutting the drainage introduction pipe is performed in a state where it is detached from the trap body and along the cutting marks, so that the work becomes easy. Therefore, unlike the related art, the operation is simplified, and there is no damage to the trap body and no debris remaining.

When the cutting mark is formed by a thin annular groove, the cutting can be performed easily, and the thin annular groove guides the direction of the cutter or the like, so that the cut surface is finished finely. The effect that it can be obtained is obtained.
