Abstract: A dishwasher according to the present invention comprises: a tub providing a washing space; a sump communicating with the tub through a recovery hole, and storing washing water; and a flow path portion installed on one surface of the tub, and supplying washing water to the tub and the sump. 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.

Abstract: Disclosed is a dishwasher including a tub, a door, a sump, a rack, a spray arm, a water guide including a supply flow-path for movement of the wash water from the sump and a supply port formed in the supply flow-path, a supply unit including a support body for receiving the wash water, a connection pipe extending from the support body to the spray arm, and an spray arm coupler, and a connection member including a coupling body coupled to the water guide and the support body, and a through-hole formed in the coupling body. The supply unit includes a rearwardly protruding insertion portion, and the connection member includes protrusions spaced apart from each other to define an insertion space for the protruding insertion portion, so that the supply unit is coupled to the water guide as the protruding insertion portion is inserted into one of the insertion space.
