The present invention relates to an automatic opening and closing drainage basin cover for a sink, and more specifically, to an automatic opening and closing drainage basin cover for a sink, which is a cover used in a drainage basin for a sink. The present invention installs a plurality of hinge-coupled opening and closing wings capable of blocking a path through which cleaning water is discharged on a bottom surface of a cover main body, thereby being possible to prevent bad smell flowing backward into the drainage basin by sealing a discharging path while the opening and closing wing adheres to an end portion of the discharging path by a weight when the sink isn′t used and being possible to discharge the cleaning water while the opening and closing wing is lifted by the discharged cleaning water when the sink is used. 본 발명은 싱크대 자동개폐 배수통 커버에 관한 것으로서, 보다 상세하게는 싱크대의 배수통에 사용되는 커버로써, 커버본체의 저면에 세척수가 배출되는 통로를 차단할 수 있는 힌지결합된 개폐날개를 다수 설치한 것으로, 싱크대 미사용시에는 개폐날개가 무게에 의해 배출로 단부에 밀착되어 배출로를 밀폐함으로써, 배수통으로 역류하는 악취를 방지할 수 있도록 하고, 싱크대를 사용하게 되는 경우에는 개폐날개가 배출되는 세척수에 의해 자동으로 들리면서, 세척수를 배출할 수 있도록 하는 싱크대 자동개폐 배수통 커버에 관한 것이다.
