Abstract
The present invention relates to a dishwasher. The dishwasher according to the present invention includes a tub for providing a washing space, a rack for accommodating dishes in the tub, a spray nozzle for spraying wash water toward the dishes accommodated in the rack, a sump for supplying the wash water to the spray nozzle, a pump for pumping the wash water stored in the sump to the spray nozzle, a supply pipe connecting the sump and the spray nozzle, and an air jet generator disposed in a supply flow path formed by the supply pipe to suck outside air to the wash water flowing along the supply pipe and crush the air to thereby form air bubbles.

A dishwasher comprising:
- a tub that defines a washing space;
- a sump disposed below the tub and configured to receive washing water;
- a spray nozzle disposed in the tub and configured to spray the washing water into the washing space, the spray nozzle comprising:
- an upper nozzle comprising a plurality of upper arms that define upper nozzle holes, and
- a lower nozzle disposed below the upper nozzle, the lower nozzle comprising a plurality of lower arms that define lower nozzle holes;
- a pump configured to supply the washing water from the sump to the spray nozzle;
- a supply pipe that connects the pump to the spray nozzle;
- and
- an air jet generator configured to generate air bubbles in the washing water flowing along the supply pipe,
- wherein the supply pipe is configured to supply the air bubbles to the washing space through the upper nozzle holes or the lower nozzle holes,
- wherein the supply pipe comprises a first expansion portion connected to the air jet generator, and
- wherein the air jet generator comprises:
- a contraction portion configured to decrease pressure of the washing water flowing in the air jet generator,
- an air suction portion opened to an outside of the air jet generator and configured to introduce air into the contraction portion, and
- a second expansion portion configured to increase the pressure of the washing water flowing in the air jet generator to thereby crush the air introduced from the air suction portion.
