Abstract

Described is a washing machine, which includes a tank and a basket, said basket being concentrically located within the tank, a sump formed therein, a driving shaft coupled by one end portion thereof to the basket, an engine coupled to said driving shaft in a direct or indirect manner, a propeller partially located in said sump and driven by one end portion of said driving shaft, the propeller including at least a scrub means, a centre and a tile, and a water column for re-circulating water from the lower portion of the basket towards the upper portion thereof, the washing machine is characterised in that: said scrub means have a transversal section formed by at least three circumference curve sections; the lower surface of the propeller has at least a wing, which along with the sump, acts as a centrifugal pump for generating a washing flow; and said washing flow is led through the water column. In a preferred embodiment, said driving shaft is coupled to a solar gear, which is useful for rotating at least a satellite gear, a mini-propeller being located over the upper surface of the tile and between the scrub means, where said satellite gear is coupled to an axis intended to rotate said mini-propeller.
