In the present invention, the drainage assembly 4 is used for leading out and draining the washing water in the outer tub, and the drum washing machine of the present invention may be an upper drainage drum washing machine or a lower drainage drum washing machine. Specifically, when the drum washing machine is an upper drain drum washing machine, the drain assembly 4 includes a drain pump 41, a connection pipe 42, and a drain pipe 43 (it is this structure shown in fig. 1). The drain pump 41 and the outer cylinder are connected to both ends of the connection pipe 42, respectively, and the first communication member 32 is connected to the connection pipe 42. When washing or rinsing is completed, the washing water in the outer tub is discharged by the drain pump 41, and when it is necessary to clean the lower portion of the wrinkle part of the window mat 2, the washing water in the connection pipe 42 is discharged by the action of the pump member 31 through the first communication member 32, the pump member 31, and the second communication member 33 in order, thereby circulating the washing water and cleaning the lower portion of the wrinkle part of the window mat 2. When the drum washing machine is a lower drain drum washing machine, the drain assemblies are a connection pipe 42, a drain pipe 43 and a drain valve 44 (this is the structure shown in fig. 6).
