Abstract

L'invention concerne un lave-vaisselle ayant une cuve de lavage permettant de recevoir un objet devant être lavé, une unité de lavage permettant de laver l'objet devant être lavé dans la cuve de lavage, un système d'alimentation en eau permettant d'alimenter de l'eau de lavage dans la cuve de lavage, un système d'évacuation permettant d'évacuer l'eau de lavage en provenance de la cuve de lavage vers l'extérieur du lave-vaisselle, et un conduit d'évacuation qui est mis en communication avec le système d'évacuation. De plus, le lave-vaisselle comporte une unité de détection de turbidité qui détecte les informations associées à la turbidité de l'eau de lavage dans le conduit d'évacuation et qui est mise en œuvre au niveau du conduit d'évacuation, et une unité de commande permettant de changer et de commander les conditions de fonctionnement de l'unité de lavage en fonction des informations associées à la turbidité de l'eau de lavage détectée par l'unité de détection de turbidité. L'unité de commande compare les valeurs détectées par l'unité de détection de turbidité soit dans un état dans lequel il n'y a pas d'eau soit dans un état dans lequel il y a de l'eau après l'alimentation en eau par le système d'alimentation en eau au commencement de l'opération. En conséquence, le lave-vaisselle détermine si oui ou non la valeur détectée par l'unité de détection de turbidité dans l'état dans lequel il y a de l'eau est adoptée comme valeur de référence des informations associées à la turbidité de l'eau de lavage.
