摘要： A drum washing machine includes: an inner drum (17) with an inner drum opening; an inner drum door (6) mounted at the inner drum opening in an opened/closed manner; a position detection device, configured to detect whether the inner drum door (6) is locked; and a door closing hindering device (55), configured to apply force for hindering closing of the inner drum door (6). By means of the arranged door closing hindering device (55), force for hindering closing of the inner drum door (6) is generated when the inner drum door (6) is closed. When the inner drum door (6) is not locked, the inner drum door (6) is opened by a certain angle. The phenomenon that the position detection device misjudges that the inner drum door (6) is locked well due to the fact that the inner drum door (6) is not locked but still closed at a drum opening or the opening angle is very small is avoided.
