A washing machine control method wherein the detergent dissolution amount is increased

Abstract

Embodiments provide a control method suitable for a washing machine having a drum and a motor which moves the drum. The control method includes the detergent dissolution step having the steps of taking detergent and water, then detecting the load amount, determining the unbalanced load amount predetermined for the load amount, determining the water level in the washing machine, and rotating the motor at least twice consecutively at low and high speeds if the unbalanced load amount and the water level are below the predetermined value.

1 . A control method which is suitable for a washing machine having a tub wherein a washing process is performed, a drum which is disposed in the tub, a motor which moves the drum, a heater which heats water in the tub and a detergent dispenser wherein a detergent to be used in the washing process is loaded, characterized by a detergent dissolution step having the steps of detecting a load amount, determining an unbalanced load amount predetermined by a manufacturer for the load amount, taking detergent and water, determining a water level in the washing machine, and rotating the motor at least once consecutively at relatively low speed and at relatively high speed if the unbalanced load amount and the water level are below a value predetermined by the manufacturer. 
     
     
         2 . The control method as in  claim 1 , characterized by the detergent dissolution step comprising rotating a drum motor of the washing machine at least once at speeds below 100 rpm and at speeds above 200 rpm. 
     
     
         3 . The control method as in  claim 2 , characterized by the detergent dissolution step comprising rotating the drum motor of the washing machine at least once at 90 rpm and 300 rpm, consecutively. 
     
     
         4 . The control method as in  claim 1 . characterized by the step of measuring a foam level during the detergent dissolution step. 
     
     
         5 . The control method as in  claim 4 , characterized by ending the detergent dissolution step if the foam level measured for a certain period of time is above the level determined by the manufacturer. 
     
     
         6 . The control method as in  claim 1 , characterized by detecting an amount of dirt and increasing a number of repetitions of the detergent dissolution step if the amount of dirt is above a level determined by the manufacturer. 
     
     
         7 . The control method as in  claim 1 , characterized by taking the amount of detergent predetermined by the manufacturer in the step of taking water and detergent according to the amount of unbalanced load determined in the step of determining the amount of unbalanced load. 
     
     
         8 . The control method as in  claim 7 , characterized by taking an average amount of detergent predetermined by the manufacturer if the determined unbalanced load amount is less than the threshold unbalanced load amount, and taking an increased amount of detergent predetermined by the manufacturer compared to the average amount if the determined unbalanced load amount is more than the threshold unbalanced load amount. 
     
     
         9 . The control method as in  claim 1 , characterized by heating the water in the tub by activating the heater, determining a temperature of the water, and activating the detergent dissolution step when the temperature of the water reaches a limit temperature value predetermined by the manufacturer. 
     
     
         10 . The control method as in  claim 1 , characterized by increasing a number of repetitions of the detergent dissolution step if a water inlet temperature is below a value determined by the manufacturer. 
     
     
         11 . The control method as in  claim 1 , characterized by the detergent dissolution step which is applied in a rinsing step. 
     
     
         12 . The control method as in  claim 1 , characterized by a softener taking step wherein the softener is taken from the detergent dispenser and the detergent dissolution step which is applied in the softener taking step.
