Abstract

La présente invention a trait à une machine à laver et une sécheuse à structure de conduit améliorée. Un meuble support (100) forme une enveloppe externe de la machine à laver et de la sécheuse, et une cuve (200) est fixée au sein du meuble support (100). Un tambour (250) est fixé à rotation dans la cuve (200). Etant donné qu'un conduit de séchage (300) est fixé dans une portion supérieure de la cuve (200) qui est décalé vers un côté par rapport à une vue de face de la cuve (200), un espace d'utilisation du meuble support (100) est amélioré et l'équipement peut être d'un encombrement réduit. Le conduit de séchage (300) est construit avec deux éléments constitués par une partie inférieure (310) et une partie supérieure (320) formées par l'extension d'une partie d'évacuation (330) à partir d'une portion d'extrémité du conduit de séchage (300), de sorte que le nombre de pièces et le nombre de processus d'assemblage sont réduits et la productivité en est améliorée. Etant donné que la partie d'évacuation (330) et la partie inférieure (310) sont constituées en un corps unique, cela permet d'empêcher l'endommagement et la fuite d'air, provoqués dans une portion de raccordement par vibration, et le bruit d'écoulement produit par celles-ci. La partie d'évacuation (330) se prolonge en oblique dans un sens de rotation du tambour (250) et une partie de guidage s'étend dans une direction tangentielle par rapport à un sens de rotation du tambour (250) à une portion d'extrémité de la partie d'évacuation (330), fournissant ainsi de l'air au tambour (250) en douceur. Un conduit de condensation (400) présente une extrémité reliée au conduit de séchage (300) et l'autre extrémité reliée à l'intérieur de la cuve (200). Une unité de chauffage (800) est disposée au sein du conduit de séchage (300) et un ventilateur de circulation (350) est prévu dans l'autre extrémité du conduit de séchage (300) à laquelle est relié le conduit de condensation.
