Pulsator for a washing machine

A pulsator for a washing machine, said pulsator comprising:

• a base plate fixed to a shaft of the washing machine to be rotated according to a rotation of the shaft;
• a plurality of stirring blades downwardly slanted from the center of said base plate to an outer periphery thereof in a sector form on an upper surface of said base plate and for defining at least one concave collecting basin between adjacent stirring blades on the upper surface of said base plate;
• and
• at least one subsidiary stirring blade radially formed between said plurality of stirring blades, said at least one subsidiary stirring blade having a size different from that of said plurality of stirring blades.

A pulsator for a washing machine, said pulsator comprising:

• a base plate fixed to a shaft of the washing machine to be rotated according to a rotation of the shaft;
• a plurality of first stirring blades downwardly slanted from the center of said base plate to the outer periphery thereof in a sector form on an upper surface of said base plate and for defining at least one first concave collecting basin between first adjacent stirring blades on the upper surface of said base plate;
• and
• a plurality of second stirring blades formed apart from said plurality of first stirring blades by a predetermined distance and for defining at least one second concave collecting basin between second adjacent stirring blades and between said plurality of first stirring blades on the upper surface of said base plate, said plurality of second stirring blades each having a size different from that of said plurality of first stirring blades and the same shape as that thereof, a center of said plurality of first stirring blades and said plurality of second stirring blades is disposed at an eccentric position apart from the center of said base plate by a predetermined distance.
