PURPOSE: A drum washing machine is provided to reduce a width of wave in the needed rotation number with aligning and offsetting each original vibrated number by separating a system having one original vibrated number to two original vibrated numbers with combining a counter weight. CONSTITUTION: A drum washing machine comprises a body(11) of the washing machine, an outer tub(12), an inner tub(13), a transferring device of power, an elongating spring(14), a damper(15), and a vibration absorber. The driving device comprises a driving motor(21) and a driving shaft(22) to transferring the rotating force of the driving motor(21). The transferring device of power comprises a driving pulley(23) and a connecting pulley(24) transferred the rotating force of the driving shaft(22), a rotating shaft(26) and the connecting pulley(24). The vibration absorber contains a counter weight(31) and an elastic buffering member to align and to reduce the vibration generated in the outer tub(12) at a washing process. The elastic buffering member is installed to do a role as a spring and a damper by composing a fixing bolt and a buffering portion, and the elastic buffering member is to do a role of a dynamic vibration absorber with the counter weight(31). |
