Controlling method of washing machine

Abstract

A controlling method of a washing machine is disclosed. A controlling method of a washing machine includes spinning to rotate a drum at a first speed to dehydrate the laundry, water draining to drain water from the drum, water supplying to supply water to a tub, while rotating the drum at a second speed for the laundry to be closely in contact with an inner circumferential surface of the drum, and penetration rinsing while rotating the drum at the second speed or at a third speed to rinse the laundry. According to the controlling method, a time taken to perform a rinsing cycle may be reduced. Furthermore, rinsing efficiency may be improved together with the reduced time of the rinsing cycle.

1 . A controlling method of a washing machine comprising:
 rotating a drum at a first speed to extract water from the laundry;   removing water from a tub;   supplying water to the tub while rotating the drum at a second speed; and   supplying water to the drum while rotating the drum to rinse the laundry.   
   
   
       2 . The controlling method of  claim 1 , wherein the first speed is more than 600 rpm to dehydrate the laundry. 
   
   
       3 . The controlling method of  claim 1 , wherein in the step of removing water, the rotation speed of the drum is reduced until a predetermined speed higher than a minimum drum speed at which the laundry is closely in contact with an inner circumferential surface of the drum. 
   
   
       4 . The controlling method of  claim 1 , wherein the second speed is equal to or higher than a minimum drum speed at which the laundry is closely in contact with the inner circumferential surface of the drum. 
   
   
       5 . The controlling method of  claim 1 , wherein in the step of supplying water to the tub, water is supplied up to a predetermined height lower than a distance between the tub and the drum. 
   
   
       6 . The controlling method of  claim 1 , wherein in the step of supplying water to the drum, water held in the tub is circulated during the rotation of the drum. 
   
   
       7 . The controlling method of  claim 1 , wherein in the step of supplying water to the drum, the circulated water is supplied in at least one of a horizontal direction and a vertical direction along an inside of the drum. 
   
   
       8 . The controlling method of  claim 1 , wherein in the step of supplying water to the drum, the drum is rotated at a speed such that the water penetrates through the laundry closely in contact with an inner circumferential surface of the drum to perform rinsing. 
   
   
       9 . The controlling method of  claim 1 , further comprising rotating the drum at the second speed during the step of supplying water to the drum. 
   
   
       10 . The controlling method of  claim 1 , further comprising rotating the drum at a third speed different from the second speed during the step of supplying water to the drum. 
   
   
       11 . The controlling method of  claim 1 , further comprising rotating the drum at a third speed higher than the second speed during the step of supplying water to the drum. 
   
   
       12 . The controlling method of  claim 1 , further comprising supplying the water to the drum by spraying. 
   
   
       13 . The controlling method of  claim 1 , wherein rotation of the drum is about a non-vertical axis. 
   
   
       14 . A controlling method of a washing machine having a tub and a drum within the tub, the method comprising:
 rotating the drum to extract water from the laundry;   removing water from the tub;   supplying water to the tub while rotating the drum so that the laundry is distributed around an inner circumferential surface of the drum and in close contact with the inner circumferential surface of the drum; and   supplying water to the drum while rotating the drum while the laundry is distributed around the inner surface of the drum and in close contact with the inner circumferential surface of the drum.   
   
   
       15 . The controlling method of  claim 14 , further comprising rotating the drum during the step of supplying water to the drum at a speed that is the same as a speed at which the drum is rotated during the step of supplying water to the tub. 
   
   
       16 . The controlling method of  claim 14 , further comprising rotating the drum during the step of supplying water to the drum at a speed that is different from a speed at which the drum is rotated during the step of supplying water to the tub. 
   
   
       17 . The controlling method of  claim 14 , further comprising rotating the drum during the step of supplying water to the drum at a speed that is faster than a speed at which the drum is rotated during the step of supplying water to the tub. 
   
   
       18 . The controlling method of  claim 14 , further comprising supplying the water to the drum by spraying. 
   
   
       19 . The controlling method of  claim 14 , wherein rotation of the drum is about a non-vertical axis. 
   
   
       20 . The controlling method of  claim 14 , wherein the laundry is relatively uniformly distributed around the inner circumferential surface of the drum during the steps of supplying water to the tub and supplying water to the drum.
