[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a drainage device used for a drain port or the like.

[0002]

2. Description of the Related Art A conventional drain port in a bathroom, for example, is shown in FIG.
As described above, an upper plate d provided with a cutout c for drainage at the lower end of a leg b is disposed at a drainage port a provided with a trap g provided with a strainer h at a lower portion to discharge the drainage f. .

[0005] Further, as shown in FIG. 5, an upper plate d is disposed through a gap in a drain port a provided with a plurality of steps e, so that a drain f
Has been discharged.

[0004]

However, of the above-mentioned conventional techniques, in the former case, the cutout for drainage is small, and the drainage capacity of the strainer is low, so that the amount of drainage is small.
There is a problem that drainage cannot be performed smoothly.

[0005] Further, since the legs have cutouts, there is a problem that dust easily accumulates in a gap between the drain port and the upper dish, and furthermore, when the dust accumulates, the upper dish cannot be easily removed. Furthermore, even if the strainer is clogged and the drainage capacity is reduced, it is difficult to recognize until the wastewater flows backward from the drainage port, and it may be delayed to notice and cause water leakage from other parts.

Further, in the latter case, since only the upper perforated plate is attached to the drain port and the strainer is not attached to the drain port, easily trapped debris flowing along with the drainage is generated in the gap between the drain port and the upper perforated plate. And the drainage is not smooth, and further, when the refuse is collected, the upper eye cannot be easily removed.

Therefore, the present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a drainage device capable of increasing the amount of outflow and performing drainage smoothly.

[0008]

In order to achieve the above-mentioned object, in a drainage device according to the present invention, a strainer is attached to a drain port, wherein the strainer includes a plurality of bosses having a predetermined height around the circumference at predetermined intervals. An outflow portion is formed between the bosses, and a plurality of outflow holes are formed.The upper surface is formed substantially flat on the strainer, and the leg portion is formed on the back surface at the boss position. It is characterized by placing an upper plate that has been set.

[0009]

The strainer is mounted on the step of the drain, and the upper plate is mounted on the boss of the strainer by mounting the legs of the upper plate.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to FIGS. At a drain position on the floor 4, a drain port 1 having a predetermined diameter and depth and having a step 11 at the lower end is formed, and a trap 5 is attached to a lower portion of the drain port 1.

The strainer 3 attached to the step portion 11 of the drain port 1 is for removing dust flowing together with the drain water. The strainer 3 is made of a synthetic resin and has substantially the same diameter as the drain port 1. Bosses 31 having a predetermined height are integrally provided at predetermined intervals around the upper surface of the strainer 3 (edge portion).

The boss 31 has an outflow portion 33 formed between adjacent bosses 31.
By setting the height, the shape and the number, the flow rate of the drainage 6 from the drainage port 1 can be adjusted much.

A large number of slit-shaped outflow holes 32 having an arbitrary shape and a groove width are formed in the flat plate portion 34 surrounded by the boss 31.

The upper dish 2 is placed on a strainer 3, and its upper surface is formed in a substantially flat plate shape.
At the position of the boss 31, a leg 21 whose upper surface is almost the same height as the floor 4 is integrally provided.

[0015]

The present invention is configured as described above, and has the following effects. The flow rate of drainage can be increased by the arrangement position, height, shape, quantity, etc. of the bosses formed on the strainer.

Further, since the refuse is collected in the strainer and the upper plate has no steps or cutouts, the upper plate and the strainer are easy to manufacture and also easy to remove dirt.

Further, the strainer is at a height close to the floor surface, and even if the strainer is clogged, the drainage can immediately overflow with sewage, and the clogging can be found at an early stage. Leakage can be prevented beforehand. Since the strainer can be easily removed by removing the upper tray, the strainer can be reused after dirt is washed with water.
