Laundry processing device and method for controlling same

Abstract

The laundry processing device according to the present invention comprises a plurality of washing units which wash independently of each other, and if vibration exceeding a configured value is generated while a single washing unit is washing, then water is supplied to rest of the washing units and a motor is rotated, thereby reducing the vibration.

1 . A laundry processing device comprising:
 a first washing unit which performs washing;   a first controller which controls operation of the first washing unit;   a second washing unit which is installed in a lower portion of the first washing unit to be in contact with the first washing unit, and performs washing independently;   a vibration sensor which is disposed in a contact portion of the first washing unit and the second washing unit to detect vibration; and   a second controller for controlling the second washing unit to be supplied with water in response to the vibration detected by the vibration sensor, in a state where the second washing unit does not perform washing.   
     
     
         2 . The laundry processing device of  claim 1 , wherein the vibration sensor is disposed in the contact portion of the first washing unit and the second washing unit to detect a stack state of the first washing unit and the second washing unit. 
     
     
         3 . The laundry processing device of  claim 1 , wherein the second controller controls the second washing unit to be supplied with water, when the vibration amount detected by the vibration sensor is equal to or greater than the set value. 
     
     
         4 . The laundry processing device of  claim 1 , wherein the second controller controls the second washing unit to be supplied with water, if it is determined that the first washing unit is in an unbalance state in response to the vibration detected by the vibration sensor. 
     
     
         5 . The laundry processing device of  claim 1 , wherein the second controller controls the motor of the second washing unit to rotate at a preset speed, after the water is supplied to the second washing unit. 
     
     
         6 . The laundry processing device of  claim 1 , wherein the second controller controls the second washing unit to perform tub cleaning, when the amount of vibration detected by the vibration sensor is less than the set value after the water is supplied to the second washing unit and the set time is elapsed. 
     
     
         7 . The laundry processing device of  claim 1 , wherein the second controller controls the second washing unit to be supplied with water in response to the vibration detected by the vibration sensor in a state where the second washing unit does not perform washing, when a vibration detecting activation command is inputted through a second input unit provided in the second washing unit. 
     
     
         8 . The laundry processing device of  claim 1 , wherein the second controller adjusts the amount of water supplied to the second washing unit in response to an amount of vibration detected by the vibration sensor, when the water is supplied to the second washing unit. 
     
     
         9 . A method for controlling a laundry processing device comprising a first washing unit and a second washing unit for performing washing in an independent washing space, wherein the first washing unit is disposed above the second washing unit, the method comprising:
 a start step of performing washing according to an inputted setting by the first washing unit;   a detection step of detecting a vibration amount by a vibration sensor disposed in a contact portion of the first washing unit and the second washing unit; and   a control step of controlling the second washing unit to be supplied with water, in response to a vibration detected by the vibration sensor, in a state where the second washing unit does not perform washing.   
     
     
         10 . The method of  claim 9 , wherein the control step comprises:
 a comparison step of comparing the vibration amount detected by the vibration sensor with a set value; and   a water supply control step of controlling the second washing unit to be supplied with water, when the detected vibration amount is equal to or greater than the set value.   
     
     
         11 . The method of  claim 9 , wherein the control step comprises:
 a determination step of determining whether the first washing unit is in an unbalance state in response to a vibration detected by the vibration sensor; and   a water supply control step of controlling the second washing unit to be supplied with water, when it is determined that the first washing unit is in the unbalance state.   
     
     
         12 . The method of  claim 9 , further comprising a motor control step of controlling the motor of the second washing unit to rotate at a preset speed, after the water is supplied to the second washing unit. 
     
     
         13 . The method of  claim 9 , further comprising the steps of:
 re-detecting the vibration amount through the vibration sensor, after the water supply to the second washing unit is completed; and   stopping an operation of the second washing unit and being on standby, when the re-detected vibration amount is less than the set value, and controlling the motor of the second washing unit to rotate at a preset speed, when the re-detected vibration amount is equal to or greater than the set value.   
     
     
         14 . The method of  claim 10 , further comprising a step of controlling the second washing unit to perform a tub cleaning, when the amount of vibration that is detected by the vibration sensor after an elapse of a set time becomes less than the set value.
