The flow passage portion includes: a water supply passage connected to a water supply source and receiving washing water; a first flow passage connected to the water supply passage and receiving washing water, and supplying washing water to the tub; and a second flow passage connected to the water supply passage and receiving washing water, and supplying washing water to the sump. The present invention has the advantages in that washing water can be supplied simultaneously to the tub and the sump, and washing water flowing in reverse in the sump can be prevented even when there is negative pressure in washing water being supplied to the sump.
