Method for controlling laundry treatment apparatus

Abstract

An aromatherapy dispensing system is disclosed. In various embodiments, the aromatherapy dispensing system includes a housing; a puck tray positioned proximate an interior section of the housing, the puck tray configured to receive a puck comprising or retaining an aromatic material; a fan assembly configured to draw ambient air into the housing, circulate the ambient air about the puck, and expel an aromatic fragrance outside of the housing into the ambient air; and a circuit module configured to store power and drive the fan assembly.

1 . A method for controlling a laundry treating apparatus including a tub where water is stored, a drum disposed inside the tub to store laundry therein, and a heater configured to heat the drum by generating an eddy current in the drum, the method comprising:
 a motion execution step of alternately performing a stirring motion to rotate the drum with a first number of rotations creating a centrifugal force smaller than 1 G, and a heat transfer motion to rotate the drum with a second number of rotations creating a centrifugal force equal to or greater than 1 G; and   a heating step of heating the drum by operating the heater,   wherein when dryness of the laundry reaches preset reference dryness, an execution time of the heat transfer motion is set to be greater than an execution time of the stirring motion.   
     
     
         2 . The method of  claim 1 , wherein when the dryness of the laundry is smaller than the preset reference dryness, the execution time of the stirring motion and the execution time of the heat transfer motion are set to be the same as each other. 
     
     
         3 . The method of  claim 1 , wherein a rotation direction of the drum set in the stirring motion and a rotation direction of the drum set in the heat transfer motion are the same as each other. 
     
     
         4 . The method of  claim 1 , wherein the first number of rotations is set to a number of rotations causing the laundry to fall, roll, or slide at a vertical level equal to or lower than a vertical level of a horizontal line passing through a rotation center of the drum. 
     
     
         5 . The method of  claim 1 , wherein a drying step composed of the heating step and a heat exchange step is divided into a preheating period, a constant drying rate period, and a falling drying rate period, and the reference dryness is set to a value between highest dryness and lowest dryness defining the constant drying rate period. 
     
     
         6 . The method of  claim 1 , wherein the reference dryness is set to dryness where a moisture content of the laundry is in a range of 30% to 20%. 
     
     
         7 . The method of  claim 1 , wherein the heating step is started simultaneously with the motion execution step or is started after start of the motion execution step. 
     
     
         8 . The method of  claim 1 , wherein the heating step is executed before start of the motion execution step, and an interval between a start time point of the heating step and a start time point of the motion execution step is set within a preset reference time. 
     
     
         9 . The method of  claim 1 , further comprising a dehydration step started before the heating step and the motion execution step are executed, wherein the dehydration step includes removing water from the laundry by rotating the drum with a number of rotations creating the centrifugal force equal to or greater than 1 G. 
     
     
         10 . The method of  claim 9 , further comprising a stirring heating step started before the dehydration step is executed, wherein the stirring heating step includes heating the drum by operating the heater while rotating the drum at a number of rotations creating the centrifugal force smaller than 1 G. 
     
     
         11 . The method of  claim 10 , wherein the number of rotations of the drum set in the stirring heating step is set to be equal to or smaller than the number of rotations of the drum set in the stirring motion. 
     
     
         12 . The method of  claim 1 , wherein the heating step includes controlling a temperature of the drum to maintain a temperature of the laundry equal to or lower than 90 degrees Celsius. 
     
     
         13 . The method of  claim 12 , wherein the heating step includes maintaining the temperature of the drum equal to or lower than 100 degrees Celsius. 
     
     
         14 . The method of  claim 12 , further comprising a cooling step of lowering the temperature of the laundry by rotating the drum when the heating step and the motion execution step are completed. 
     
     
         15 . The method of  claim 14 , wherein a number of rotations set in the cooling step is set to be smaller than the first number of rotations.
