Abstract: A drum washing machine comprises an inner drum rotatable. Both ends of the inner drum are closed and rotatably mounted on a supporting device through rotating shafts, respectively. A side wall of the inner drum is provided with an input port for taking and putting items. A sealing inner cover capable of being opened/closed is mounted at the input port. A water flow passage for feeding water and/or draining water is arranged in at least one of the rotating shafts at both ends of the inner drum. The whole inner drum may be made into a drum without any hole. During the washing process, washing water is held in the inner drum, and the inner drum rotates to wash clothes. The two closed ends of the inner drum are rotatably mounted on the supporting device through the rotating shafts, thus realizing rotation of the inner drum.
