DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom drain trap used for a unit bath or the like, and more particularly, to collecting hair and the like in drain water.

[0002]

2. Description of the Related Art In a unit bath or the like, a so-called bath / trap having a trap structure is provided, which collects wastewater from a bathtub and a washing place. FIG. 3 is a sectional view of a conventional bus / trap. On the upstream side of the U-shaped trap 1, a drain pipe 3 from a bath tub and a drain pipe 5 from a washing place that opens upward are formed, and drain water from both is merged into the trap 1. It is designed to flow in.
A basket 7 for collecting hair is attached to the opening of the drain pipe 5, and the basket 7 can collect hair and the like mixed in drainage from the washing place. In the conventional bus / trap configured as above,
When water is flushed from the washing place, the hair and the like mixed in the drainage are collected in the basket 7, and only water free of foreign matter flows into the trap 1. As a result, it is possible to prevent a situation in which the pipe 1 is clogged even in the trap 1 that is unlikely to flow quickly.

[0003]

However, in the conventional bath and trap, since there is only one basket 7, the ability to collect hair and the like is not sufficient. Etc. are trap 1
And often clogged pipes. Further, in the conventional bath / trap, there is no means for collecting foreign matter between the drain pipe 3 from the bathtub and the trap 1, and hair and the like from the bathtub drainage also stay in the trap 1 to prevent clogging of the pipe. The cause of occurrence was increasing. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a bath / trap that can improve the ability to collect foreign matter in washroom drainage and can collect foreign matter in bathtub drainage, thereby reducing the frequency of pipe clogging. It is intended to reduce the amount.

[0004]

In order to achieve the above object, a bathroom drain trap according to the present invention has a vertical tubular portion formed at an opening on the upstream side of the trap, and an upper portion of the tubular portion. The opening serves as a drainage port for the washing basin, and the drainage port from the bathtub is formed on the boundary between the cylinder and the trap, with a step portion projecting inward of the cylinder in the bath / trap connected to the side surface of the cylinder. A hair collecting basket is detachably provided at an upper opening of the cylindrical portion, and a hair collecting plate having a plurality of holes and connected to the basket via a chain is placed on the step portion. is there.

[0005]

The hair and the like mixed in the drainage from the washing place are first collected in a basket, and the hair and the like that have passed through the basket are collected in a downstream hair collecting plate. In addition, hair and the like mixed into the drainage from the bathtub will be collected on the hair collecting plate, and foreign matter that could not be removed with only one basket can be collected, reducing the amount of foreign matter entering the trap. I do. In addition, when removing the hair and the like, if the basket is lifted, the hair collecting plate is simultaneously lifted by the chain, and the foreign matters collected in both the basket and the hair collecting plate can be removed at the same time.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a bathroom drain trap according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional view of a bath / trap according to the present invention, and FIG. 2 is a perspective view of a basket. A vertical cylindrical portion 13 is formed in the opening on the upstream side of the trap 11, and the upper opening of the cylindrical portion 13 is a drain port from the washing place. A drain pipe 15 from the bathtub is connected to the side surface of the cylindrical portion 13, and the bathtub drainage from the drain pipe 15 flows to the trap 11 through the cylindrical portion 13.

A hair collecting basket 17 is attached to an opening above the cylindrical portion 13, and the basket 17 can collect hair and the like mixed in drainage from a washing place. One end of a stainless chain 19, which is a chain, is attached to the lower surface of the basket 17, and the other end of the stainless chain 19 is connected to the center of a stainless plate 23, which is a hair collection plate having a plurality of holes 21 formed therein. . Therefore, with the basket 17 held, the stainless steel plate 23 is hung horizontally via the stainless steel chain 19. The stainless steel plate 23 is formed in such a size that its outer shape is loosely fitted in the cylindrical portion 13. Further, a step 25 is provided at the boundary between the trap 11 and the cylindrical section 13, and the stainless plate 23 is placed on the step 25. That is, basket 17
The stainless steel plate 23 is placed on the step portion 25 in a state where is attached to the opening above the cylindrical portion, and covers the upstream opening of the trap 11. Therefore, the drainage from both the washing place and the bathtub passes through the stainless steel plate 23. The basket 17, the stainless steel chain 19, the stainless steel plate 23, and the step portion 25 constitute a bus / trap 27 mainly.

The bus / trap 27 constructed as described above
In the above, when water is flushed from the washing place, the hair and the like mixed in the drainage are collected in the basket 17 first.
The hair and the like that have not been collected by the basket 17 and have passed through the basket 17 are collected on the stainless steel plate 23. Further, even when water is flushed from the bathtub, the water passes through the stainless steel plate 23, so that the hair and the like mixed in the drainage are collected by the stainless steel plate 23. Therefore, the conventional basket 17
Foreign matter that could not be collected only by itself can be collected, and also foreign matter can be collected from the drainage from the bath tub, which was conventionally directly drained, greatly increasing the entry of foreign matter into the trap 11. Can be reduced.

When removing the collected hair and the like, if the basket 17 is lifted, the stainless steel plate 23 is simultaneously lifted by the stainless steel chain 19, so that the hair is collected in both the basket 17 and the stainless steel plate 23. Hair and the like can be easily removed. As described above, according to the bus / trap 27 according to the present embodiment, it is possible to reduce the amount of foreign matter entering the trap 11, so that clogging of the pipe can be significantly reduced, and the collected hair and the like can be removed very easily. Can be.

The basket 17, the stainless steel plate 23
Is not limited to the circular shape shown in FIG. 2. For example, as long as the cylindrical portion 13 has a rectangular shape, the cylindrical portion may have a rectangular shape.

[0011]

As described above in detail, according to the bathroom drain trap (bath / trap) according to the present invention, the step is formed at the boundary between the cylindrical portion and the trap, and the basket is connected to the basket via the chain. Since the hair collecting plate to be connected was placed on the step,
Hair passing through the basket is collected by the hair collecting plate downstream, and hair mixed in the drainage from the bath can also be collected by the hair collecting plate, thereby significantly improving the foreign matter collecting ability. As a result, the frequency of occurrence of pipe clogging can be reduced.
