The dehydration administration is explained as follows.

First, the dehydration stroke in the inner tub 20 is performed by the rotational force transmitted from the driving motor 3 to the clutch means 50 by dehydration by switching of a clutch spring (not shown) provided in the clutch means 50. It is transmitted to the inner tank 20 through the 25, the dehydration stroke in the inner tank 20 is made by the centrifugal force generated at this time by rotating the inner tank 20 at a high speed.

And the dehydration stroke in the auxiliary washing tank 120 is driven through the boss 171 through the boss 171 by the rotational force transmitted from the driving motor 3 to the driven pulley (170a) by the moving member 179 under the control of the microcomputer ( 170, the rotational force transmitted to the driven shaft 170 is transmitted to the auxiliary washing tank 120 through the dehydration shaft 125 by the switching of the clutch spring provided in the clutch means 150.

Therefore, the auxiliary washing tank 120 is rotated at a high speed, so that the dehydration stroke is performed in the auxiliary washing tank 120, and after a predetermined time elapses by the control of the microcomputer, a series of washing strokes is completed.

As described in detail above, the separation washing apparatus according to the present invention has the following effects.

First, by washing the soft laundry, such as lingerie separate from the general laundry, it is possible to prevent the soft laundry from being damaged or shrunk during washing.

Second, by washing different kinds of laundry at the same time, it is possible to reduce the number of washing water and power consumption, and also to reduce the washing time.
