Abstract
An agitator for a washing machine includes a base, an agitating post extending eccentrically upwardly from the base, and agitating blades upstanding from the base. An upper surface of the agitating post is inclined with respect to horizontal by an angle up to 75 degrees. The blades extend radially in circumferentially spaced relationship around the entire base. Alternatively, the blades could extend parallel to one another on only one half of the base, the other half including an upward protrusion extending circumferentially at a location adjacent an outer periphery of that other half.
Claims11
A pulsator for a washing machine, comprising:
- a base having a first vertical center axis;
- the base including a coupling portion coaxial with the first center axis and adapted for connection to a drive shaft to define a vertical axis of rotation coinciding with the first center axis;
- a plurality of agitating blades extending upwardly from the base, the blades arranged symmetrically with respect to the first center axis, each of the blades having circumferentially facing sides sloping generally downwardly and outwardly;
- and
- an agitating post extending upwardly from a center region of the base beyond the agitating blades, the agitating post having a second vertical center axis arranged eccentrically with respect to the first center axis and including an upper surface inclined relative to horizontal such that a highest point on the upper surface is spaced from points of intersection of the upper surface with the first and second vertical axes, respectively.
