Abstract
The present invention discloses a method for controlling laundering of a low frequency oscillation washing system to enhance the laundering effect by maintaining resonance phenomena inside of a wash tub in a resonant laundering by oscillation. The inventive method therefor includes the steps of keeping up the resonant condition by a pulsator to a first wash time at a speed of a first oscillating frequency by selecting a washing or rinsing procedure; continuously keeping up the resonant condition of the above first step to a second wash time at a speed of a second oscillating frequency; producing a speed of a third oscillating frequency to prevent the extinction of the resonant condition maintained at the second step and retain the continuous resonance; and repeatedly performing the operation through which each speed of the first, second and third oscillating frequencies is intermittently increased or decreased up to a predetermined wash time by generating an interrupt.
