PURPOSE: A drainage trap is provided to rapidly and simultaneously drain sewage and dregs generated in a sink or a kitchen using a turbulent flow. CONSTITUTION: A drainage trap(300) comprises a housing(100), an upper cover(200), an overflow pipe(110), branch pipes(120), and a floating unit. The top of the housing is opened. The upper cover seals the opened top of the housing. The overflow pipe is formed inside the housing and is composed of an inner pipe(113) and an outer pipe. The branch pipes are formed on the outer surface of the housing. The floating unit floats dregs contained in sewage by generating a turbulent flow in the sewage. |
