Description

Noise reduction device for toilet

The present invention relates to a washing water noise reduction device of the toilet.

In general, toilets installed in apartments, including apartments, generates a lot of noise as the washing water is drastically drained to the lower floor while causing a heavy vortex movement in the toilet. This noise is transmitted to the lower level through the drain pipe and the slab layer.

As a method of fundamentally dealing with such a noise generation problem, it is preferable to block the noise generated primarily at the point where the washing water first falls.

As described above, the prior art for blocking the noise caused by the wash water of the toilet bowl is Korean Utility Model No. 20-0320645 (name of the design: the drainage pipe noise device of the toilet bowl), Korean Patent No. 10-0495393 (name of the invention) : It is disclosed in the noise reduction elbow toilet only and Korea Patent No. 10-0631621 (name of the invention: low noise elbow pipe structure for toilet).

In the case of the noise reduction device of the drain pipe part of the toilet disclosed in the prior art, by the noise pipe body of the soft resin material embedded in the toilet drain line, the fall noise of the washing water discharged from the toilet is characterized in that it is reduced.

In addition, according to the toilet dedicated elbow, the sewage discharged from the toilet is vertically dropped and the inner surface portion colliding with the elbow is formed with a gentle inclination angle to reduce the collision noise.

In addition, by forming the elbow portion rounded to the radius of curvature that can minimize the wash water flow resistance, thereby reducing friction noise due to sewage.

In addition, according to the low noise elbow fitting pipe structure for toilet bowl, by providing a fixing key for preventing the twisting when the pipe is tightened, to prevent the twisting of the sound absorbing pipe.

In addition, the streamlined protrusion is formed in the flow direction of the filthy water so that the noise of the pipe is reduced while the filthy water flows along the streamlined protrusion.

In addition, the pipe wall through which the sewage flows is rounded to be curved to reduce noise of the pipe.

Such prior arts still have the disadvantage of not helping to improve the living environment due to the noise generated when draining, because of the low ability to block the noise generated by the sewage discharged to the elbow.

The present invention is devised to improve such a conventional problem.
