A drum-type washing machine comprising: an outer tub , which is disposed within a machine housing ; a drum , which is disposed in the outer tub and rotatable about a horizontal axis or about an axis inclined with respect to a horizontal direction; a rotating body , which is disposed in the drum and having a protruding portion in contact with laundry on a surface of the rotating body ; and a driving portion , which comprises a driving motor and is configured to transmit a torque of the driving motor to the drum and the rotating body so as to rotate the drum and the rotating body at different rotation speeds; characterized in that the drum-type washing machine further comprises: a controlling portion for controlling an operation of the driving portion ; and a detecting portion for detecting a rotation speed of the driving motor ; wherein the controlling portion is configured to perform a reduction control for reducing a load when a magnitude of the load applied to the rotating body exceeds a predetermined magnitude in at least one of following processes: a washing process and a rinsing process, and the controlling portion is further configured to adjust an electric power to be supplied to the driving motor so that the driving motor rotates at a target rotation speed, when the rotation body is rotated under control of the controlling portion , and perform the reduction control, when the rotation speed of the driving motor reaches the target rotation speed that is not greater than a threshold value; wherein the controlling portion is configured to rotate the driving motor so that the drum rotates at a rotation speed at which a centrifugal force acting on the laundry in the drum becomes greater than the gravity, as the reduction control. an outer tub , which is disposed within a machine housing ; a drum , which is disposed in the outer tub and rotatable about a horizontal axis or about an axis inclined with respect to a horizontal direction; a rotating body , which is disposed in the drum and having a protruding portion in contact with laundry on a surface of the rotating body ; and a driving portion , which comprises a driving motor and is configured to transmit a torque of the driving motor to the drum and the rotating body so as to rotate the drum and the rotating body at different rotation speeds; characterized in that the drum-type washing machine further comprises: a controlling portion for controlling an operation of the driving portion ; and a detecting portion for detecting a rotation speed of the driving motor ; a controlling portion for controlling an operation of the driving portion ; and a detecting portion for detecting a rotation speed of the driving motor ; wherein the controlling portion is configured to perform a reduction control for reducing a load when a magnitude of the load applied to the rotating body exceeds a predetermined magnitude in at least one of following processes: a washing process and a rinsing process, and the controlling portion is further configured to adjust an electric power to be supplied to the driving motor so that the driving motor rotates at a target rotation speed, when the rotation body is rotated under control of the controlling portion , and perform the reduction control, when the rotation speed of the driving motor reaches the target rotation speed that is not greater than a threshold value; wherein the controlling portion is configured to rotate the driving motor so that the drum rotates at a rotation speed at which a centrifugal force acting on the laundry in the drum becomes greater than the gravity, as the reduction control. <EOS>
