Method for smoothing wrinkles of laundry in washing machine

Abstract

A method for smoothing the laundry wrinkled during a washing process in the washing machine is disclosed. When a command signal for smoothing wrinkles of the laundry in the washing machine is inputted, water supplied in the washing machine is heated to generate steam and then the generated steam is injected to the laundry in the washing machine while rotating a drum of the washing machine. Thus, wrinkles of the laundry can be smoothed in the washing machine without causing a trouble of ironing.

1 . A method for smoothing wrinkles of the laundry in a washing machine comprising: 
 heating water supplied into a washing machine and generating steam when a command signal for smoothing wrinkles of the laundry in the washing machine is inputted; and    injecting the generated steam to the laundry in the washing machine while rotating a drum of the washing machine.    
   
   
       2 . The method of  claim 1 , wherein the step of injecting steam to the laundry in the washing machine comprises: 
 terminating injection of steam to the laundry in the washing machine when a first pre-set time elapses, and rotating the drum for a second pre-set time.    
   
   
       3 . The method of  claim 2 , wherein the step of injecting steam to the laundry in the washing machine comprises: 
 stopping rotation of the drum when the second pre-set time elapses, and informing a user of completion of smoothing wrinkles of the laundry.    
   
   
       4 . The method of  claim 3 , wherein, in the step of injecting steam to the laundry in the washing machine, an alarm sound is generated or an LED (Light Emitting Diode) displaying proceeding of a process of smoothing wrinkles of the laundry is blinked in order to inform the user of completion of smoothing wrinkles of the laundry.  
   
   
       5 . A method for smoothing wrinkles of the laundry in a washing machine comprising: 
 supplying water into a steam generator of a washing machine when a command signal for smoothing wrinkles of the laundry is inputted by a user's request after a washing process of the washing machine is completed;    heating water by means of a heater installed in the steam generator to generate steam;    injecting stream generated for a first pre-set time to the laundry in the drum while rotating the drum of the washing machine; and    stopping steam-injecting when the first pre-set time elapses.    
   
   
       6 . The method of  claim 5 , wherein the step of injecting steam to the laundry comprises: 
 rotating the drum for a second pre-set time after terminating injection of steam to the laundry in the washing machine.    
   
   
       7 . The method of  claim 6 , wherein the step of injecting steam to the laundry in the washing machine comprises: 
 stopping rotation of the drum when the second pre-set time elapses, and informing a user of completion of smoothing wrinkles of the laundry.    
   
   
       8 . The method of  claim 7 , wherein, in the step of injecting steam to the laundry in the washing machine, an alarm sound is generated or an LED (Light Emitting Diode) displaying proceeding of a process of smoothing wrinkles of the laundry is blinked in order to inform the user of completion of smoothing wrinkles of the laundry.  
   
   
       9 . A method for smoothing wrinkles of the laundry in a drum-type washing machine comprising: 
 supplying water into a steam generator of a drum-type washing machine when a command signal for smoothing wrinkles of the laundry is inputted by a user's request after a washing process of the drum-type washing machine is completed;    heating water by means of a heater installed in the steam generator to generate steam;    injecting stream generated for a first pre-set time to the laundry in the drum while rotating the drum of the drum-type washing machine;    stopping steam-injecting when the first pre-set time elapses;    rotating the drum for a second pre-set time after stopping injection of steam to the laundry in the drum-type washing machine; and    stopping rotation of the drum when the second pre-set time elapses and informing a user of completion of smoothing wrinkles of the laundry.    
   
   
       10 . The method of  claim 9 , wherein in the step of injecting steam to the laundry in the washing machine, an alarm sound is generated or an LED (Light Emitting Diode) displaying proceeding of a process of smoothing wrinkles of the laundry is blinked in order to inform the user of completion of smoothing wrinkles of the laundry.
