A direct flush drainage structure. A drain pipe (2) below a container (1) is connected to a rear water collecting pipe (3) by a middle pipe (4). The middle pipe (4) is filled up when a liquid flows by. After the liquid flows by, an upper portion (5) and a bottom portion (6) of the middle pipe (4) are closed or almost closed. The middle pipe (4) has a water storage structure therein. When not flushing water, the top portion and the bottom portion of the pipe are in a closed or almost closed state and form a water seal, so that return of a smell is prevented and blocking is not likely to be incurred.
