Abstract (en)

[origin: EP3988701A1] Provided are a drum washing machine and a control method thereof. The drum washing machine includes: an inner drum (3) having a washing chamber capable of independently containing washing water; an inner drum drainage port (9) disposed in the inner drum (3); and a drainage sealing device installed on the inner drum drainage port (9) to control opening and closing thereof, wherein the drainage sealing device includes a drainage channel (7) communicating with the inner drum drainage port (9) and a blocking component (8) that controls opening and closing of the drainage channel (7). The drum washing machine realizes the opening and closing control over the inner drum drainage port through the drainage sealing device, the drainage sealing device includes the drainage channel communicating with the inner drum drainage port and the blocking component that controls the opening and closing of the drainage channel, the opening and closing control over the inner drum drainage port is converted into on-off control of the drainage channel, the blocking component can be designed to have different motion states by using the shifting of working states of the inner drum, thereby switching on-off of the drainage channel, the structure is simple, and control is easy to realize.
