Abstract: Disclosed is a dishwasher. The dishwasher includes a tub; an injection module for injecting washing water toward dishes; a sump for supplying washing water to the injection module; a washing pump for feeding the washing water stored in the sump to the injection module; and an air jet generator for receiving some of the washing water fed from the washing pump to form air bubbles in the washing water and to discharge the washing water to the sump, wherein the air jet generator forms a flow path perpendicular to the bottom surface of the tub or the ground and includes a decompression portion for depressurizing the flowing washing water and a pressing portion for pressing the washing water flowing downstream of the decompression portion; an air crushing pipe having an air inlet hole so as to introduce external air in downstream of the decompression portion; an air tap for crushing air existing 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.
