Abstract

L'invention concerne un tiroir de lessive et un lave-linge. Le tiroir de lessive comprend un corps de boîte (1), le corps de boîte (1) comprenant une sortie de liquide (11), la sortie de liquide (11) étant dotée amovible d'une structure de sortie de liquide (2), la structure de sortie de liquide (2) comprenant une soupape unidirectionnelle. La structure de sortie de liquide (2) du tiroir de lessive permet l'alimentation automatique en lessive pour une seule utilisation ou plusieurs utilisations, et en même temps, interrompt la sortie de liquide en direction inverse ; l'agencement d'étanchéité amovible rend l'entretien plus simple, étant pratique et sans fuites, et lors d'une obstruction, celle-ci peut se résoudre au fil du temps ; en outre, l'ajout de liquide peut également être effectué au moyen de la sortie de liquide (11), et la structure de sortie de liquide présente une structure simple et une fiabilité élevée.
