The present invention relates to a noise-reducing drain structure for a toilet to drain wastewater through an elbow tube (6), which is connected to an outlet of the toilet, and through a horizontal drain (7). The drain structure comprises soundproofing pipes (10, 30) which are freely bent and arranged inside the curved elbow tube (6) and the horizontal drain (7) and which have a smooth inner surface to reduce noise transmission to the outside during the flushing of the toilet. According to the present invention, a flexible hose or a dual tube is arranged, as a flexible soundproofing tube, inside the elbow tube and the horizontal drain of the toilet to effectively prevent noise from being transferred to the outside during the flushing of the toilet, thereby preventing noise from being transferred to the outside of the bathroom or neighboring houses, and a soundproofing layer is attached to the outer surface of the soundproofing tube, thereby effectively removing problems caused by the flushing noise of the toilet. In addition, the present invention can be simply constructed and easily applied to a drain structure of an existing toilet. |
