suitable for rinsing the washing object when the water introduction is finished water introducing valve 120 is closed and motor 150 is driven to generate a water stream suitable for rinsing the washing object the water stream necessary for the rinsing step is generated in the same manner as in the washing step that is when the washing mode is a dry mode rotary blade 110 rotates right as in a first direction for about 2 4 seconds is stationary for about 5 6 seconds rotates left as in a second direction opposing to the first direction for about 2 4 seconds and then is stationary for about 5 6 seconds which as one cycle is repeated continuously for about two minutes when the washing mode is a silk mode rotary blade 110 rotates right as in a first direction for about 0 3 0 5 seconds is stationary for about 5 6 seconds rotates left as in a second direction opposing to the first direction for about 0 3 0 5 seconds and then is stationary for about 5 6 seconds which as one cycle is repeated continuously for about one to three minutes preferably about two minutes after generating the water steam for the rinsing step for a predetermined time the rotation of rotary blade 110.
