- a normal signal is not received from the first sensor unit, it can be determined that the sub drum is not mounted or the sub drum is mounted improperly. For example, if no signal is received from the first sensor unit 54 while the rotation angle of the drum 30 is detected to be 360 degrees by the second sensor unit 25, the control unit 100 determines that the sub drum 50 It can be determined that it is not mounted on the drum 30 (S630-N).
- the control unit 100 performs water supply from the water supply unit 18 to the drum 30 (S670). In this case, the position control of the drum is not performed for supplying water.

The rotation angle is set in advance according to the arrangement relationship of the first sensor unit 54, the outer water supply guide 570, and the water supply unit 18.
- the rotation angle of the sub drum 50 is measured by the second sensor unit 25 while the sub drum 50 rotates at a very low rpm and is transmitted to the control unit 100. [ When the controller 100 determines that the measured rotation angle has reached the predetermined rotation angle, the controller 100 controls the braking unit 110 to stop the sub-drum 50.

[ When the controller 100 determines that the measured rotation angle has reached the predetermined rotation angle, the controller 100 controls the braking unit 110 to stop the sub-drum 50.
- the sub drum 50 has various sliding angles to slide from a point where braking is started due to the weight of the laundry and the laundry water contained therein as well as its own weight. In particular, in the case where rmp is relatively high, such a sliding angle may vary.
- the controller 100 corrects the predetermined rotation angle. For example, if the sliding angle of the sub drum 50 is large enough to allow the outer water supply guide 570 to pass under the water supply unit 18, the control unit 100 corrects the predetermined rotation angle value to be small, The preset rotation angle value is increased.
- the rpm at this time is larger than the above-mentioned 3 rpm and rotates at 15 to 25 rpm, which is lower than 40 to 90 rpm in general washing, so that a very small load is applied to the driving unit 14.
