The device comprises an inlet (3), which has an opening (4) for the water to be evacuated. A cover (10) forms an annular passage (9), through which the water to be evacuated can flow away. At least one noise-reducing element (16-25) is provided, which, at or above a predetermined load, introduces air into the flow of the water, so that an intake of air through the said annular passage (9) is reduced. As a result of the introduced air, the flow in the inlet (3) and, in particular, in the drainpipe (6), even in a part-load situation, is stabilized, and noises arising from turbulence and vibration can thus be reduced. 42 37 101:3 \7 /6 16 111 39 - 16b 10'
