Abstract: A dish washing machine having a structure allowing wash water to be evenly sprayed into a washing tub. The dish washing machine includes a cabinet forming an external appearance of the dish washing machine, a washing tub arranged in the cabinet and allowing dishes to be washed therein, a dish basket arranged in the washing tub to accommodate the dishes, a spray unit to spray wash water into the washing tub, a diversion unit arranged inside a flow passage of wash water to divert the wash water sprayed from the spray unit, and a guide member coupled to one side of the diversion unit to allow the diversion unit to move within the washing tub. As the spray unit and the diversion unit are provided, a dead zone which wash water does not reach may be eliminated, and divided and intensive washing may be implemented in the washing tub.
