The invention discloses a seal ring of the drum washing machine. The seal ring is made of rubber and comprises a first flange, a second flange and a connecting wall located between the first flange and the second flange, wherein the connecting wall is in a bent state, so that a groove is formed between the connecting wall and the second flange, and a drainage hole is formed in the second flange; ahydrophobic area is arranged on the radial inner surface of the area, close to the drainage hole, of the connecting wall, the hydrophobic area has high surface roughness, the hydrophobic effect is achieved under the high surface roughness, and the other areas have low surface roughness. By forming the hydrophobic area on the surface, close to the drainage hole, of the seal ring, sewage is easierto drain from the drainage hole and is not easy to remain, so that the sanitation problem of the seal ring is improved. The invention further discloses a drum washing machine with the sealing ring. 本发明公开了滚筒洗衣机的密封圈，其由橡胶制成，包含第一凸
