A dishwasher filter device based on micro-nano aeration includes a cylinder for accommodating washing liquid and a filter unit. The filter unit is in communication with an inner cavity of the cylinder by a water inlet pipe. The filter unit is connected to a micro-nano bubble generator by a third pipe. The micro-nano bubble generator is connected to a water outlet unit. The water outlet unit includes a fourth pipe connected to the micro-nano bubble generator and a dissolved air release assembly connected to the other end of the fourth pipe. The dissolved air release assembly is disposed at a bottom of the cylinder.

A dishwasher includes: a spray module which sprays washing water toward dishes; a sump which supplies washing water to the spray module; a pump which pumps washing water stored in the sump to the spray module; and an air jet generator which receives a part of washing water pumped from the pump to form an air bubble in washing water and discharges the air bubble to the sump, wherein the air jet generator comprises: a decompression portion which decreases a pressure of washing water; 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 configured to crush the air contained in washing water that passed through the pressing portion.

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.

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.

A dish washer includes a tub defining a washing space, a base disposed below the tub and defining a space below the tub, a sump disposed in the space defined by the base and configured to store water, a washing pump disposed in the space defined by the base and configured to supply the water stored in the sump to the washing space, and an air jet generator having a venturi shape including an air inlet provided on one side, an inlet having a downward opening, and an outlet provided above a bottom surface of the tub. The air jet generator further includes a tub mounting portion fixing an upper portion of the air jet generator to the bottom surface of the tub and a base fixing portion disposed below the tub mounting portion, the base fixing portion coupling a lower portion of the air jet generator to the base.

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.
