[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device to be attached to a drainage hole of a waterproof floor pan of a bus unit, for example.

[0002]

2. Description of the Related Art Drainage traps are provided on floor drainage instruments such as bath units in order to prevent the odor of sewage from flowing back into a living room. In addition, since hair and the like are mixed in the floor drainage of the bathroom, a hair stopper is arranged under the eye plate.

[0003]

[Problems to be Solved by the Invention] Some of the above drainage devices have a structure in which the distance from the bristle to the sealing surface of the drainage trap is extremely long. For example, in the case of bus units for middle- and high-rise houses, the waterproof floor pan is installed at a position that is considerably higher than the floor of the building. The structure is set at a lower position.

[0004] According to the drainage device having such a structure, there is no problem in terms of function, but since the distance from the hair stopper to the water sealing surface is long, water accumulated in the hair stopper and the like after draining falls as water droplets. There was a problem that a loud sound was generated when the water was sealed, and the sound was very unpleasant.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a water droplet from the hair stopper even if the distance from the stopper to the sealing surface of the drain trap is long. An object of the present invention is to provide a drainage device having a structure capable of reducing a sound generated by falling.

[0006]

A configuration for achieving the above object will be described with reference to FIG. 1 corresponding to an embodiment. The present invention is directed to a drain hole 10a provided in a waterproof floor pan 10, for example. And a drain port 1 communicating with the bottom of the vertical pipe 1a via a bend 1c.
b, and a drain trap 1 configured such that a water sealing surface L is formed at a predetermined height position below the upper end of the vertical pipe 1a.
And a device provided with a clasp 2 mounted on an upper portion in the vertical tube 1a and a perforated plate 3 disposed above the clasp 2, the bottom portion is opened and a top plate 41 is provided on an upper portion. A cylindrical member 4 having a plurality of through holes 41a... 41a formed in the top plate 41 is arranged inside the vertical pipe 1a of the drain trap 1, and the top plate 41 of the member 4 is It is characterized by being located between the stop 2 and the sealing surface L.

[0007]

The water drops that have fallen from the hair stopper 2 hit the top plate 41 of the member 4, stay on the top plate 41 once, and then fall through the through holes 41 a of the top plate 41 to seal water. As described above, the water drop from the bristle stopper 2 falls to the sealed water with one cushion, so that the falling distance to the sealed water is shortened.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view showing the structure of the embodiment of the present invention, and FIG. 2 is a perspective view showing only the soundproof member 4 of the embodiment.

The drain trap 1 includes a vertical pipe 1a, a U-bend 1c for sealing water at a predetermined height level below the upper end of the vertical pipe 1a, and the vertical pipe 1a through the bend 1c. Is provided with a drain port 1b that communicates with the In addition, vertical pipe 1
A hair stopper 2 is screwed into the upper end in the area a.

A flange 1 is provided on the periphery of the upper end of the vertical pipe 1a.
d is integrally formed, and with the flange 1d aligned with the peripheral edge of the drain hole 10a of the waterproof floor pan 10, the retaining ring 5 is screwed into the vertical pipe 1a to thereby form the waterproof floor pan of the drain trap 1. 10 can be mounted. Then, the perforated plate 3 is mounted by being fitted into the retaining ring 5. Reference numeral 6 denotes a packing for ensuring watertightness around the drain hole 10a. Further, a pipe 7 connected to the bottom of the drain trap 1 is a pipe for connection with drainage of another part.

A soundproof member 4 is inserted into the vertical pipe 1a of the drain trap 1. The soundproof member 4 is placed at the bottom of the drain trap 1 and its top plate 41 is
And below the hair stopper 2.

As shown in FIG. 2, the soundproof member 4 has a cylindrical shape with an open bottom, and its outer diameter is several mm smaller than the inner diameter of the vertical pipe 1a. A large number of through-holes 41a are formed in the top plate 41 of the soundproof member 4, and slits 42a are formed below the side wall 42 from the bottom to a position above the water sealing surface L. Is cut out. Therefore, the floor drainage from the waterproof floor pan 1 flows out smoothly from the drainage port 1b without stagnation at the position where the soundproof member 4 is disposed. As the material of the soundproof member 4, a material having excellent corrosion resistance such as stainless steel or resin is used.

[0013]

[Effects of the Invention] As described above, according to the present invention, a cylindrical member having a plurality of through holes in the top plate and an open bottom is disposed inside the vertical pipe of the drain trap. Then, since the top plate was located between the water sealing surface and the bristle stop, the water droplets from the bristle did not fall directly into the seal water, and after putting one cushion on the top plate of the tubular member, Collision with water at short fall distance. Thus, even when the distance between the bristle stopper and the water sealing surface is long, the sound of falling water drops can be reduced.
