Abstract

L'invention concerne un appareil d'entretien du linge (100) comprenant une pompe (105) destinée à pomper le liquide de lavage, la pompe (105) comprenant une chambre d'aspiration (107) comportant une tubulure d'aspiration (109) destinée à assurer la liaison fluidique avec une conduite d'aspiration, la pompe (105) comprenant un filtre (121) destiné à filtrer les impuretés du liquide de lavage, et la chambre d'aspiration (107) comprenant une ouverture d'insertion de filtre (119) permettant l'insertion du filtre (121) dans la chambre d'aspiration (107), le filtre (121) comprenant une cartouche filtrante (123) qui est placée à l'intérieur de la chambre d'aspiration (107), les impuretés entraînées dans le liquide de lavage pouvant se fixer à la cartouche filtrante (123), et le filtre (121) comportant un bouchon de filtre (125) qui est conçu pour fermer de manière étanche l'ouverture d'insertion de filtre (119). Le bouchon de filtre (125) peut être retiré de l'ouverture d'insertion de filtre (119) par application d'une force qui est de plus en plus grande à mesure que la quantité d'impuretés fixées à la cartouche filtrante (123) augmente. La cartouche filtrante (123) et le bouchon de filtre (125) sont assemblés au moyen d'une liaison libérable de façon réversible (145). Lorsque le bouchon de filtre (125) est retiré de l'ouverture d'insertion de filtre (119), la liaison libérable de façon réversible (145) est libérée dès lors que la force passe au-dessus d'une valeur seuil de force prédéfinie, afin de permettre de retirer efficacement les impuretés fixées à la cartouche filtrante (123).
