Abstract:
Disclosed in the present invention is a drum washing machine, comprising: a machine housing, a front panel of the machine housing being provided with a feed opening; an outer drum, arranged in the machine housing, an outer drum opening of the outer drum being opposite the feed opening; an inner drum, rotatably arranged in the outer drum and capable of independently holding washing water during washing; and a machine door, mounted on the feed opening of the front panel in an openable and closable manner; wherein the machine door comprises an outer cover for sealing the feed opening, an outer drum cover for sealing the outer drum opening, and an inner drum cover for sealing the inner drum opening, the outer cover being fixedly connected to the outer drum cover, and the inner drum cover being rotatably connected to the outer cover and/or the outer drum cover by means of a rotating assembly. With regard to the structural features of different components of a washing machine, the present invention solves the problem of sealing of a feed opening, an outer drum opening and an inner drum opening by means of an integrated machine door, and the inner drum cover and the inner drum opening are fixedly connected and rotate synchronously; and compared with a dynamic sealing mode, the present invention achieves a better sealing effect, a stronger sealing stability and a longer sealing life.
