Impeller type roll mode washing method and washing maching adopting the method

Abstract

A rolling mode washing method of a washing and rinsing cycle is disclosed. The method uses at least three pulsators slantedly positioned within a washing tub. The pulsators are positioned with respect to one another such that each pulsator is adjacent to two different pulsators. The washing tub is filled with water and materials to be cleaned are placed within the washing tub. A pair of adjacent pulsators are rotated in opposite directions with respect to one another. The pair of rotating pulsators lifts the materials to be cleaned. A second pair of adjacent pulsators are rotated in the same direction with respect to one another. The second pair of rotating pulsators creates a force to push the materials to be cleaned.

What is claimed is: 
     
         1 . A rolling mode washing method using pulsators during a washing and rinsing cycle, comprising:
 filling a washing tub with water, the washing tube including a first pulsator, a second pulsator, and a third pulsator, where the first, second, and third pulsators are slantedly positioned within the washing tub with respect to one another such that each pulsator is adjacent to the other pulsators;   placing materials to be cleaned within the washing tub;   rotating the first pulsator and the second pulsator in a first direction;   rotating the second pulsator in a second direction rotationally opposite of the first direction.   
     
     
         2 . The rolling mode washing method of  claim 1 , further comprising stopping the rotation of the first pulsator, the second pulsator, and the third pulsator, and rotating the first pulsator and the second pulsator in the second direction and rotating the third pulsator in the first direction. 
     
     
         3 . The rolling mode washing method of  claim 1 , where the first direction is clockwise. 
     
     
         4 . The rolling mode washing method of  claim 3 , where rotation of the second pulsator in the first direction creates a side auxiliary force to push the material to be cleaned toward the first pulsator and the second pulsator. 
     
     
         5 . The rolling mode washing method of  claim 3 , where rotation of the first pulsator and the third pulsator in opposite directions lift the material to be cleaned. 
     
     
         6 . The rolling mode washing method of  claim 3 , where the rotation of the first pulsator and the third pulsator in opposite directions furl the material to be cleaned. 
     
     
         7 . The rolling mode washing method of  claim 3 , where the rotation of the first pulsator and the third pulsator in opposite directions cast the material to be cleaned. 
     
     
         8 . The rolling mode washing method of  claim 1 , where the first direction is counterclockwise. 
     
     
         9 . The rolling mode washing method of  claim 8 , where rotation of the first pulsator in the first direction creates a side auxiliary force to push the material to be cleaned toward the second pulsator and the third pulsator. 
     
     
         10 . The rolling mode washing method of  claim 8 , where rotation of the second pulsator and the third pulsator in opposite directions lift the material to be cleaned. 
     
     
         11 . The rolling mode washing method of  claim 8 , where rotation of the second pulsator and the third pulsator in opposite directions furl the material to be cleaned. 
     
     
         12 . The rolling mode washing method of  claim 8 , where rotation of the second pulsator and the third pulsator in opposite directions case the material to be cleaned. 
     
     
         13 . A rolling mode washing method of a washing and rinsing cycle using at least three pulsators slantedly positioned within a washing tub with respect to one another such that each pulsator shares an interface with two different pulsators, comprising:
 filling the washing tub with water;   placing materials to be cleaned within the washing tub;   rotating a first pair of adjacent pulsators in opposite directions with respect to one another to lift the materials to be cleaned;   rotating a second pair of adjacent pulsators to create a side auxiliary force to push the materials to be cleaned towards the first pair of adjacent pulsators.   
     
     
         14 . The rolling mode washing method of  claim 13 , where the second pair of adjacent pulsators comprise pulsators that are unique from the first pair of adjacent pulsators. 
     
     
         15 . The rolling mode washing method of  claim 14 , where the second pair of adjacent pulsators are rotated in opposite directions with respect to one another. 
     
     
         16 . The rolling mode washing method of  claim 14 , where the second pair of adjacent pulsators are rotated in similar directions with respect to one another. 
     
     
         17 . The rolling mode washing method of  claim 13 , where the second pair of adjacent pulsators comprise one pulsator in common with the first pair of adjacent pulsators and one pulsator separate from the first pair of adjacent pulsators, and where the second pair of pulsators rotate in opposite directions with respect to one another. 
     
     
         18 . The method of  claim 13 , where rotation of the first pair of adjacent pulsators furl the material to be cleaned. 
     
     
         19 . The method of  claim 13 , where rotation of the first pair of adjacent pulsators cast the material to be cleaned. 
     
     
         20 . The method of  claim 13 , where the first pair of adjacent pulsators and the second pair of adjacent pulsators are rotated simultaneously.
