Abstract

Le lave-vaisselle de l'invention comprend : une cuve qui forme une chambre de lavage ; une unité de pulvérisation qui pulvérise de l'eau de lavage dans la chambre de lavage ; un bassin collecteur qui comprend une première partie de raccordement ; une pompe qui peut être raccordée au bassin collecteur et qui comprend une seconde partie de raccordement ; et un support de pompe qui relie la première partie de raccordement du bassin collecteur et la seconde partie de raccordement de la pompe pour monter la pompe sur le bassin collecteur. Afin d'empêcher la pompe de se séparer du bassin collecteur, la première partie de raccordement et/ou de la seconde partie de raccordement peut comprendre une première partie d'extension s'étendant dans une première direction et une seconde partie d'extension s'étendant à partir de la première partie d'extension dans une seconde direction croisant la première direction.
