PURPOSE: A drum washing machine is provided which has improved assembling, productivity and persistence, as a motor is connected at the back of a drum with a series connection to unify the motor parts and the drum parts. CONSTITUTION: A drum washing machine includes a rotatory power generator rotating one side an axis of the drum(51) with generated electromagnetic force by supplying power in a turbo(40) and installed at the back of the drum. The rotatory power generator includes: a bearing housing(210) molded insert at the back of the turbo(40) so that a left bearing is inserted into the center of the inside and an oil room is inserted so that washed water is not leaked from the turbo(40); a fixation unit(220) which is installed at the inside of the bearing housing(210); a motor housing(240) in which the fixation unit(220) fixes with a screw or a bolt to be able to compress in the direction of the bearing housing(210) and a right bearing(242) which is installed at the center of the inside; an axis of a motor(250) which is supported to be able to be rotated by the left bearing(212) and the right bearing(242) and can be rotated with the outside of the axis of the drum(51) at the same period by unity of creation; a rotation unit(260) which is installed at between the outside of the axis of the motor(250) and the fixation unit(220) and is fixed to rotate with the axis of the motor(250) at the same period; a rotation number sensor(280) which is installed to sense the rotation number of the axis of the drum(51) by using a drum nut and washer being set in the axis of the drum(51) protruded to the back of the right bearing(242) and a chopper cover(290) is installed at the back of the motor housing(240) so as to protect the rotation number sensor(280). |
