Abstract: A dish washer includes: a tub defining a washing space, a spray module disposed inside the tub and configured to spray water to the washing space, a sump configured to store water, a washing pump configured to supply the water stored in the sump to the spray module, and an air jet generator disposed below a bottom surface of the tub and configured to receive a portion of the water discharged from the washing pump to generate air bubbles in the water and discharge the water having air bubbles to the washing space. The air jet generator includes an air pulverizing pipe including a first pipe providing a cross-sectional area reducing in a water flowing direction, a second pipe providing a cross-sectional area increasing in the water flowing direction, and an air tab disposed at an upper portion of the second pipe.
