The invention relates to a drum washing machine. The invention provides a high speed rotating dehydrating drum washing machine with dehydration performance improved and abrasion of corrugated pipe reduced during high-speed rotation dehydration. In the high speed dehydration, movement of water drum during high speed rotation dehydration can be lowered by suppressing air escaping from the outer peripheral to the external space, fetching external air to the inner peripheral of the drum, arranging a circular wind duct communicating the drum outer peripheral with high pressure and the drum inner peripheral with low pressure, or rotating the wind delivery fan for drying and delivering air into the inner peripheral forcibly. Moreover, movement of water drum in high speed rotating dehydrating canbe lowered by arranging a spring with elasticity varying according to displacement or a spring spacingly disposed with the drum at front of the drum. According to the arrangement described above, dehydration performance of high speed rotating dehydration can be improved, and reliability of abrasion reduction of corrugated pipe in high speed rotating dehydration can also be improved.
