Method of washing laundry

Abstract

The present invention discloses a method of washing laundry by controlling the intensity of washing according to the temperature of washing water. In the method of washing laundry using a washing machine including a cabinet having a laundry inlet for putting the laundry in, an outer tub disposed in the cabinet for reserving a washing water, and an inner tub disposed in the outer tub for rotating the laundry, a temperature of a washing water supplied to the outer tub is sensed. Then, the intensity of washing laundry is controlled according to the sensed temperature of the washing water.

1 . A method of washing laundry using a washing machine including a cabinet having a laundry inlet for putting the laundry in, an outer tub disposed in the cabinet for reserving a washing water, and an inner tub disposed in the outer tub for rotating the laundry, the method comprising the steps of: 
 a) sensing a temperature of a washing water supplied to the outer tub; and    b) controlling intensity of washing laundry according to the sensed temperature of the washing water.    
   
   
       2 . The method of  claim 1 , wherein the intensity of washing is controlled in inverse proportion to the temperature of the washing water.  
   
   
       3 . The method of  claim 1 , wherein in the step b), a season is determined according to the temperature of the washing water, and the intensity of washing laundry is controlled according to the determined season.  
   
   
       4 . The method of  claim 1 , wherein in the step b), at least one of a rotating speed and a rotating time of the inner tub is controlled according to the temperature of the washing water.  
   
   
       5 . The method of  claim 4 , wherein in the step b), the rotating speed of an inner tub is controlled in inverse proportion to the temperature of the washing water.  
   
   
       6 . The method of  claim 4 , wherein in the step b), the rotating time of the inner tub is controlled in inverse proportion to the temperature of the washing water.  
   
   
       7 . A method of washing laundry using a washing machine including a cabinet having a laundry inlet for putting the laundry in, an outer tub disposed in the cabinet for reserving a washing water, and an inner tub disposed in the outer tub for rotating the laundry, the method comprising the steps of: 
 a) sensing volume of laundry putted in the inner tub;    b) supplying a washing water to the laundry;    c) sensing a temperature of the supplied washing water; and    d) controlling intensity of washing laundry, which is decided according to the sensed volume, by reflecting a season that is determined according to the sensed temperature of the washing water.    
   
   
       8 . A method of washing laundry using a washing machine including a cabinet having a laundry inlet for putting the laundry in, an outer tub disposed in the cabinet for reserving a washing water, and an inner tub disposed in the outer tub for rotating the laundry, the method comprising the steps of: 
 a) supplying washing water to the laundry;    b) sensing a temperature of the supplied washing water; and    c) determining whether the laundry is thick or thin according to the temperature of the washing water.    
   
   
       9 . The method of  claim 8 , further comprising the step of: 
 d) sensing volume of the laundry before the step a); and    e) washing laundry based on the volume and the determination of the step c).    
   
   
       10 . The method of  claim 8 , wherein in the step c), a season is determined according to the temperature of the washing water, and the laundry is determined whether it is thick or thin according to the determined season.  
   
   
       11 . A method of washing laundry using a washing machine including a cabinet having a laundry inlet for putting the laundry in, an outer tub disposed in the cabinet for reserving a washing water, and an inner tub disposed in the outer tub for rotating the laundry, the method comprising the steps of: 
 a) sensing volume of laundry putted in the inner tub;    b) supplying a washing water to the laundry;    c) sensing a temperature of the washing water supplied to the outer tub; and    d) controlling at least one of a rotating speed and a rotating time of an inner tub, which are decided according to the sensed volume, according to the temperature of the washing water.    
   
   
       12 . The method of  claim 11 , wherein in the step d), the rotating speed of the inner tub is controlled in inverse proportion to the temperature of the washing water.  
   
   
       13 . The method of  claim 11 , wherein in the step d), the rotating time of the inner tub is controlled in inverse proportion to a temperature of the washing water.
