METHOD AND APPARATUS FOR RESONANCE DETECTING OF LOW FREQUENCY VIBRATORY WASHING MACHINE

摘要

The present invention can detect the pressure in the washing tank of the low frequency vibration washing machine and the relative phase difference between the disk and proceed to the washing in the state of maintaining the optimum resonance state according to the use conditions, thereby minimizing washing deterioration and damage of the laundry The washing efficiency can be increased, and the increase in power consumption can be prevented, thereby greatly improving the efficiency and reliability of the product.;To this end, the present invention is to operate at a set frequency to detect the pressure fluctuation of the washing tub in the pressure phase measuring means when washing to generate a signal above or below a certain pressure when the pressure fluctuates at the same period as the vibration of the disk, and Detecting the position of the disk in the disk displacement measuring means to generate a signal when the disk reaches the top, bottom dead center or a certain position, and the pressure phase measuring means and the disk displacement measuring means by detecting the resonance state in the washing tank It is a resonance sensing method of low frequency vibration theta which is made to increase, decelerate, and maintain the current operating frequency according to the generated on / off signal.
