Abstract

L'invention concerne un dispositif barrière à odeurs (10), notamment un siphon, comprenant une chambre à liquide (30). Le liquide (F) qui se trouve dans la chambre à liquide (30), lorsque le niveau de liquide (FS) est suffisant, forme une barrière à odeurs entre un orifice d'entrée (21) et un raccord de sortie (60) dispositif barrière à odeurs (10). Selon l'invention, le dispositif barrière à odeurs (10) comprend un dispositif d'appoint (200) destiné à faire automatiquement l'appoint de liquide (F) dans la chambre à liquide (30). Le dispositif d'appoint (200) est configuré de telle sorte qu'il déclenche un appoint automatique du liquide (F) dans la chambre à liquide (30) lorsque le niveau de liquide (FS) dans la chambre à liquide (30) devient inférieur à un niveau de liquide minimum prédéfini.
