When the first washing mode and the second washing mode are repeatedly executed by a predetermined number of times, the driving of the motor 14 is stopped and the drainage device 40 is operated to contaminated washing water in the tub 8. Is drained to the outside of the drum washing machine (see S30).

That is, the wash water inside the tub 8 is pumped by the drain pump 36 and guided to the outside along the drainage bellows 38 and the drain hose 34.

When the washing stroke as described above is finished, the drum 10 is rotated at a high speed by the motor 14 to centrifuge the contaminated washing water contained in the laundry 50. (See S40)

Thereafter, clean water is supplied again by the water supply device 30 to the inside of the tub 8 to a predetermined level.

 In addition, the motor 14 is driven by any one of the low speed LP and the high speed MP, so that the drum 10 rotates at a low speed or a high speed to rinse the foam or various debris of the laundry 50 which has undergone the washing process. See S60)

That is, the drum washing machine 1 has a first rinsing mode in which the drum 10 is rotated at a low speed ALPM during a rinsing stroke, and the high speed ALMP during the set time in the middle of the first rinsing mode. The second rinsing mode is rotated in the same manner. (See S61, S62, S63, S64, and S65.)

The first rinsing mode and the second rinsing mode are repeatedly performed to the set number of times alternately during the rinsing stroke, and the set number of times and the second rinsing mode for repeatedly executing the first and second rinsing modes are performed. The set time is changed according to the rinsing conditions of the drum washing machine (1).

On the other hand, the 1,2 rinsing mode is the same as the operation method and the effect and the same as the first and second washing mode of the washing stroke will be omitted a detailed description thereof.

When the first rinsing mode and the second rinsing mode are repeatedly executed by a predetermined number of times, driving of the motor 14 is stopped, and the drainage device 40 is operated to rinse the water in the tub 8. Drained to the outside of the drum washing machine (1) (see S70).

This rinsing stroke is repeated several times as necessary.

When the rinsing stroke is completed, the drum 10 is rotated at a high speed by the motor 14 to completely centrifuge the laundry 50 (see S80).
