Roller washing machine

An embodiment of the invention provides a roller washing machine. The roller washing machine comprises an inner drum, an outer drum and a door seal; a gap is formed between the inner drum and the outer drum; a plurality of dewatering holes are formed in the circumferential side wall of the inner drum; the inner space of the inner drum, the multiple dewatering holes and the gap are in fluid communication and form an airflow loop; and further, the drum washing machine comprises a ventilation structure which connects the door seal and the airflow loop and is suitable for enabling the door seal and the airflow loop to be in fluid communication. According to the embodiment of the invention, the ventilation structure is arranged between the airflow loop generated in the dewatering process of the roller washing machine and the door seal, so that dewatering air generated in the dewatering process of the roller washing machine can be effectively guided to the door seal, and residual sewage at each part of the surface
