Method for water supply in laundry device

Abstract

A method for water supply in a laundry device is disclosed. An object of the present invention is to provide a method for water supply in a laundry device which prevents detergent from remaining/being stuck in/to a dispenser body by discharging detergent/wash water more smoothly. A method for water supply in a laundry device includes (a) step for supplying water; (b) step for temporarily stopping water supply for a predetermined time in the middle of the water supply; and (c) step for re-starting water supply after the predetermined time and finishing water supply to a predetermined water level.

1 . A method for water supply in a laundry device comprising: 
 (a) step for supplying water;    (b) step for temporarily stopping water supply for a predetermined time in the middle of the water supply; and    (c) step for re-starting water supply after the predetermined time and finishing water supply to a predetermined water level.    
   
   
       2 . The method for water supply in a laundry device as claimed in  claim 1 , wherein the water level of (a) and (c) step is sensed by a water level sensor which outputs frequencies corresponding to a sensed water level.  
   
   
       3 . The method for water supply in a laundry device as claimed in  claim 1 , wherein (a) step comprises steps of, 
 controlling a water supply valve based on a control signal for performing cycles to start water supply;    sensing the laundry amount during the water supply and setting a water level corresponding to the sensed laundry amount; and    defining the set water level as the predetermined water level of (c) step.    
   
   
       4 . The method for water supply in a laundry device as claimed in  claim 1 , wherein (b) step is performed, if the present water level according to the water supply of (a) step reaches a water level frequency prior to a discretional predetermined value with respect to the water level frequency corresponding to the predetermined water level, compared with the predetermined frequency corresponding to the predetermined water level of (c) step.  
   
   
       5 . The method for water supply in a laundry device as claimed in  claim 3 , wherein (b) step is performed, if the present water level according to the water supply of (a) step reaches a water level frequency prior to a discretional predetermined value with respect to the water level frequency corresponding to the predetermined water level, compared with the predetermined frequency.  
   
   
       6 . The method for water supply in a laundry device as claimed in  claim 4 , wherein the discretional predetermined value is a frequency between 0.1˜0.5 kHz.  
   
   
       7 . The method for water supply in a laundry device as claimed in  claim 4 , wherein the predetermined time for temporarily stopping the water supply in (b) step is between 1˜5 sec.  
   
   
       8 . The method for water supply in a laundry device as claimed in  claim 4 , wherein (b) step is performed at least one time after the water supply starts.  
   
   
       9 . The method for water supply in a laundry device as claimed in  claim 4 , wherein (b) step is performed at least one time during the water supply, in case that the water supply of (a) step is for a main washing.  
   
   
       10 . The method for water supply in a laundry device as claimed in  claim 9 , wherein (b) step is performed in the beginning of the water supply.  
   
   
       11 . The method for water supply in a laundry device as claimed in  claim 9 , wherein on/off of the water supply valve is alternatively repeated in (b) step.  
   
   
       12 . The method for water supply in a laundry device as claimed in  claim 11 , wherein the on/off operation, which is one time of (b) step, is repeatedly performed within 3 to 10 times.  
   
   
       13 . The method for water supply in a laundry device as claimed in  claim 1 , wherein the water supply of (c) step is finished, if the present water level according to the water re-supply reaches the predetermined water level frequency.  
   
   
       14 . The method for water supply in a laundry device as claimed in  claim 3 , wherein the water supply of (c) step is finished, if the present water level according to the water re-supply reaches the predetermined water level frequency.
