Referring to fig. 1 to 3, a drum washing machine 100 according to an embodiment of the present application mainly includes a cabinet 1, a door 2, an outer tub (not shown), a drum (not shown), a window pad 3, a filter 4, a circulation pump 5, a drain pump 6, and the like.

The casing 1 has a rectangular hollow structure, as shown in fig. 1. The inner space of the cabinet 1 is used to provide installation space for the tub, the drum, the window gasket 3, the filter 4, the circulation pump 5, the drain pump 6, and the like.

The casing 1 has a front panel 11, and a front surface of the front panel 11 is formed with an inlet 110, and the inlet 110 is selectively opened or closed. When the input port 110 is opened, laundry to be washed may be put into the drum through the input port 110 to perform washing, and laundry washed in the drum may be taken out through the input port 110. In the washing process, the input port 110 is closed to close the outer tub, thereby ensuring the normal operation of the washing process, or the input port 110 is closed to prevent dust and other substances from entering the drum when the laundry is not required to be taken or put in.

The side of the casing 1 where the inlet 110 is formed is referred to as the front side, and the side of the casing 1 facing away from the inlet 110 is referred to as the rear side.
