Title (EN) A METHOD AND ARRANGEMENT FOR PREVENTING THE SPREADING OF UNPLEASANT ODOURS FROM LAVATORY BASINS
(FR) PROCEDE ET AGENCEMENT EMPECHANT LE DEGAGEMENT D'ODEURS DESAGREABLES DE CUVETTES DE WC
Abstract:
(EN) 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.
(FR) Agencement empêchant le dégagement d'odeurs désagréables de cuvettes de WC. L'agencement comprend un réseau d'orifices d'admission (10) par lesquels de l'air est acheminé en surpression à la cuvette de WC, et un réseau d'orifices de sortie (11) par lesquels l'air est extrait de l'espace de la cuvette par aspiration. Les orifices d'admission (10) destinés à l'air sous surpression sont disposés de sorte que l'air en sortant forme une couche d'air turbulente d'une surpression donnée, dans la partie supérieure de l'espace de la cuvette, tandis que les orifices de sortie (11) sont disposés de sorte que l'air est extrait de l'espace de la cuvette, à un niveau situé au-dessous de la couche d'air. L'invention concerne également un procédé empêchant le dégagement d'odeurs désagréables d'une cuvette de toilettes.
