Abstract: A dishwasher includes a tub; an injection module; a sump for supplying washing water to the injection module; a washing pump; and an air jet generator configured to form air bubbles in the washing water and to discharge the washing water to the sump. The air jet generator forms a flow path perpendicular to a bottom surface of the tub and includes a decompression portion for depressurizing washing water and a pressing portion for pressing the washing water; an air crushing pipe having an air inlet hole to introduce external air; an air tap for crushing air in the washing water discharged from the air crushing pipe; and an air chamber disposed outside the air crushing pipe and forming a space for introducing air therein, and having an air inlet hole for communicating with the inside of the air crushing pipe at one side of the lower portion.

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.
