Abstract

L'invention concerne un lave-linge, capable de laver de manière à empêcher une rupture structurale lors du lavage du linge ordinaire et du linge délicat ensemble et sans endommager le linge délicat. Le lave-linge (1) comprend : une cuve de lavage cylindrique (4) ayant un espace de réception principal (4E) pour recevoir le linge et un axe (J) s'étendant dans une direction verticale (Z); et une boîte de réception (8). Un espace de réception secondaire (8D) est entouré par une partie de plaque incurvée (17), une paire de parties de plaque latérale (18) et une partie de plaque inférieure (19) et utilisé pour recevoir le linge (S) est formé dans la boîte de réception (8); la partie de plaque incurvée (17) est disposée, à partir de l'axe (J), face à face avec une surface périphérique interne (4G) de la cuve de lavage (4) et s'étend dans une direction circonférentielle (P) de la surface périphérique interne (4G); la paire de parties de plaque latérale (18) s'étendent jusqu'à la surface périphérique interne (4G) à partir des deux extrémités de la partie de plaque incurvée (17) dans la direction circonférentielle (P); la partie de plaque inférieure (19) s'étend jusqu'à la surface périphérique interne (4G) à partir des extrémités inférieures de la partie de plaque incurvée (17) et de la paire de parties de plaque latérale (18). L'espace de réception secondaire (8D) présente une section transversale en forme d'arc s'étendant dans la direction circonférentielle (P). La taille (D) de l'espace de sous-réception (8D) dans la direction radiale (R) se centrant sur l'axe (J) est de plus en plus petite vers une extrémité supérieure (8E) de l'espace de réception secondaire (8D).
