Abstract

L'invention concerne un pulsateur de machine à laver et une machine à laver, un corps de base (1) du pulsateur étant sous la forme d'un disque ; une partie centrale saillante (4) étant disposée au milieu du corps de base (1) du pulsateur ; la surface supérieure du corps de base (1) comprenant des pales d'agitation saillantes (2) et des rainures (3) s'étendant de la partie centrale (4) du corps de base (1) vers la périphérie du corps de base (1) ; et la surface inférieure du corps de base (1) comprenant des faces légèrement ondulées correspondant à la surface supérieure. Étant donné que les faces ondulées ne font pas saillie rigidement de la surface inférieure du corps de base (1), et aucun angle inclus rigide n'est fourni entre les faces ondulées et entre les faces ondulées et les autres faces du corps de base (1), et contrairement aux pulsateurs existants ayant une surface inférieure divisée en plusieurs petites zones, la surface inférieure du pulsateur est une grande face intégrée avec des faces ondulées, réduisant un espace mort avec la saleté s'accumulant facilement en son sein et empêchant la saleté d'adhérer facilement au fond du pulsateur.
