  • a driving of the first and second pump head 1 13, 1 15 by a worm shaft is advantageous.

Abstract

L'invention concerne un appareil de traitement du linge (100) muni d'un système de dosage (105) permettant de doser une première substance liquide et une seconde substance liquide, le système de dosage (105) comprenant un premier réservoir (107) fournissant la première substance liquide, un deuxième réservoir (109) fournissant la deuxième substance liquide, et un système de pompe (112) muni d'une première tête de pompe (113) et d'une deuxième tête de pompe (115). Le système de dosage (105) comprend un mécanisme d'entraînement commun (129) servant à entraîner la première tête de pompe (113) et la deuxième tête de pompe (115), le mécanisme d'entraînement commun (129) pouvant être entraîné dans une première direction d'entraînement (137) et dans une deuxième direction d'entraînement (139). La première tête de pompe (113) est conçue pour, dans la première direction d'entraînement (137) du mécanisme d'entraînement commun (129), refouler la première substance liquide hors du premier réservoir (107) dans une première direction de refoulement (149). La deuxième tête de pompe (115) est réalisée pour, dans la deuxième direction d'entraînement (139) du mécanisme d'entraînement commun (129), refouler la deuxième substance liquide hors du deuxième réservoir (109) dans une deuxième direction de refoulement (153).
