Abstract

La présente invention concerne une machine à laver qui comporte un corps de carrosserie, une cuve intérieure disposée dans le corps de carrosserie, un dispositif d'entraînement permettant d'entraîner la cuve intérieure en rotation et un dispositif de récupération d'eau disposé au fond de la cuve intérieure. Pendant le lavage/rinçage, la cuve intérieure sert de cuve contenant de l'eau. Un canal d'évacuation d'eau, en communication avec la cuve intérieure et utilisé pour évacuer l'eau de la cuve intérieure, est disposé sur la paroi extérieure de la cuve intérieure. Le dispositif de récupération d'eau comprend une cavité de récupération d'eau pourvue d'une ouverture supérieure. Un creux se trouve sur la paroi inférieure de la cavité de récupération d'eau. L'extrémité de sortie d'eau du canal d'évacuation d'eau s'étend vers le bas dans le creux. Selon la présente invention, le dispositif de récupération d'eau ne limite pas l'expansion de la capacité de la cuve intérieure et fournit un espace suffisant pour l'expansion de la capacité de la cuve intérieure. De plus, l'extrémité de sortie d'eau du canal d'évacuation d'eau s'étend dans le creux sur la paroi inférieure de la cavité de récupération d'eau, ce qui facilite la récupération et l'évacuation de l'eau, permet également à l'eau évacuée pendant l'élimination de l'eau de ne pas jaillir hors de la cavité de récupération d'eau et empêche la corrosion du corps de carrosserie, ainsi qu'un court-circuit résultant des projections d'eau.
