<p>An arrangement for preventing the spreading of unpleasant odours from lavatory basins. The arrangement includes an array of inlet openings (10) through which air is delivered at overpressure to the lavatory basin, and an array of outlet openings (11) through which air is extracted from the basin space by suction. The inlet openings (10) for air under overpressure are disposed so that the air exiting therefrom will form a turbulent air layer of given overpressure in the upper part of the basin space, whereas the outlet openings (11) are disposed so that air is extracted from the basin space essentially at a level which lies beneath the air layer. The invention also relates to a method for preventing the spreading of unpleasant odours from a toilet basin.</p> |
