LIQUID DISCHARGE DEVICE

摘要

A liquid drain device (100), intended for connection to a liquid drain network such as a sewer, comprises a catch tray (41), a closed stench lock space (101) with an inlet opening communicating to the catch tray (41) and an outlet opening (52) located at a higher level than the inlet opening, and an outlet (51) connected to the outlet opening (52) of the stench lock space (101). According to the invention, the drain device further has a buffer chamber communicating with the catch tray (41) via a communication opening (111). The communication opening (111) has a relatively large flow resistance. Thus, even in the case of a small construction height of the drain device, it is prevented that the stench lock space (101) is drawn empty too far because then the liquid level in the stench lock space (101) is slowly filled from the buffer chamber (110).
