WASHING MACHINE AND METHOD TO SENSE SUDS THEREOF

摘要

PURPOSE: A washing machine is provided to accurately detect bubbles excessively generated by using an accelerating sensor measuring the vibration of the washing machine. CONSTITUTION: A washing machine comprises: a control unit rotates a drum by a motor; and a control unit sensing the rotary rate of the drum through a speed sensing unit. In case the rotary rate of the drum reaches to goal RPM(Round Per Minute), the controller measures up/down displacement data by an acceleration sensor. In case the average value of the up/down displacement data is under setup value, the controller counts the generation number of bubble error.
