Washing machine with agitator

Abstract

A washing machine with agitator is disclosed. The washing machine with agitator has a washing tub of which a bottom surface protrudes axially and inwardly like a pyramid, wherein the washing tub has at least two slanted portions which slant upwardly from an edge of the bottom surface toward an inside central axis of the washing tub. A washing shaft is rotatably installed and extended vertically from a lower space in the washing machine to the bottom surface of the washing tub. A driving wheel is installed on the washing shaft, wherein a frictional surface is formed on one side of the driving wheel. At least two frictional wheels rotate and contact with the frictional surface of the driving wheel. At least two driven wheels of which a frictional surface formed on one side contacts with the frictional wheels respectively, wherein the driven wheels are rotatably installed on one surface of the slanted portions. At least two stirring blades are installed on the other surface of the slanted portions to connect with the driven wheels, thereby the stirring blades generate a rotating water flow in the washing tub. Therefore, respective rotating water flows are generated which prevent laundry gathering in the center of the washing tub from tangling. Accordingly the washing time is shortened, and the washing effect is enhanced.
