FOAM DETECTION METHOD, FOAM DETECTION DEVICE AND DRUM WASHING MACHINE

摘要

A foam detection method involves detecting water level of a drum washing machine in dewatering course, and determining whether foam formed in dewatering course of the machine is over standard according to the detection result. Furthermore,a corresponding foam detection device and a drum washing machine are also disclosed, which can carry out the corresponding foam-removing treatment so as to avoid the problem caused by the overflowed foam.
