Abstract: The present invention relates to a dishwasher.
The dishwasher of the present invention includes: a spray module which sprays washing water toward dishes; a sump which supplies washing water to the spray module; a pump which pumps the washing water stored in the sump to the spray module; and an air jet generator which receives a part of the washing water pumped from the pump to form an air bubble in the washing water and discharges the air bubble to the sump, wherein the air jet generator comprises: a decompression portion which decreases a pressure of the washing water that flows; an air suction portion which is opened to allow air to flow into the decompression portion; a pressing portion which increases pressure so as to crush the air introduced from the air suction portion; and an air tap which has a plurality of holes formed therein so as to crush the air contained in washing water that passed through the pressing portion.-

Abstract: A dish washer is provided. The dish washer includes a tub; a spray module which sprays water to the washing space, a sump in which the water is stored, a washing pump which supplies the water stored in the sump to the spray module, and an air jet generator which is disposed below a bottom surface of the tub, receives a portion of the water discharged from the washing pump to generate air bubbles in the water, and discharges the water having air bubbles to the washing space of the tub. The air jet generator includes an air pulverizing pipe which includes a first pipe which has a cross-sectional area which is reduced upward, a second pipe which is disposed above the first pipe, and has a cross-sectional area which increases upward, and an air inlet hole which is formed around a peripheral surface of the second pipe to communicate with an outside at an inlet end portion of the second pipe, and an air tab which is disposed to the upper portion of the second pipe and has a plurality of air holes, and the air pulverizing pipe includes an extended surface portion which extends in a radial direction at a discharge end portion of the first pipe and extends a area of flow path of the inlet end portion of the second pipe.
