METHOD FOR SENSING FOAM OF LAUNDRY TREATMENT MACHINE

摘要

A method for sensing bubbles of a washer is provided to prevent accident caused by bubbles and to prevent a motor from being overheated by sensing rotating time and rotational speed of the motor several times and sensing bubbles several times. A method for sensing bubbles of a washer comprises the steps of: sensing bubbles if rotational speed of a motor reaches to a first rotational speed within a predetermined time when in a dehydration process(S50); and re-sensing bubbles if bubble are not sensed and the rotational speed of the motor reaches to a second rotational speed(S60).
