The dishwasher of the present invention includes: a tub in which a dish washing space is formed; a sump which contains washing water supplied into the tub; a spray module which sprays washing water toward dishes; a pump which supplies the washing water stored in the sump to the spray module; an air jet generator which receives a part of the washing water discharged from the pump to form an air bubble in the washing water; and a discharge module which discharges the washing water containing the air bubble discharged from the air jet generator to a side surface of the tub.

Dishwasher

The present invention relates to a dishwasher that can save wash water for cleaning and a method of controlling the dishwasher. A method of controlling a dishwasher according to an exemplary embodiment of the present invention is a method of controlling a dishwasher having a circulation channel through which wash water is supplied to wash a plurality of arms by a wash pump after collecting the wash water, sprayed in to a tub from the plurality of wash arms, in a sump, and the method includes: performing a first water-supplying for supplying a predetermined amount of wash water into the dishwasher by opening a water supply valve; performing a first washing where the plurality of wash arms spray the wash water into the tub to be circulated by operating the wash pump; performing a first draining for saving recycling wash water as much as the volume of the circulation channel and draining the rest of the wash water to the outside of the dishwasher by operating the wash pump and the drain pump; and performing a second water-supplying for supplying the amount of wash water except the amount of the recycling wash water from a predetermined amount of wash water into the dishwasher by opening the water supply valve.

Dishwasher and method of controlling the same

A dishwasher includes a cabinet having a tub, a pump and at least one spray arm. The at least one spray arm has a flow path guide and first and second flow channels separated from each other. The flow path guide has a first opening to allow wash water to flow to the first flow channel and a second opening to allow wash water to flow to the second flow channel. A valve is coupled to the flow path guide and is configured to open or close one of the first opening and the second opening. The valve includes a rotatable float. The rotatable float closes the first opening while opening the second opening at a first point in time, and the rotatable float rotates to open the second opening while closing the second opening at a second point in time.

A control method for a dishwasher that includes a spray arm, a sump configured to provide a space where washing water is stored and to collect washing water sprayed from the spray arm, a housing configured to connect the sump and the spray arm, a heater located in the housing, an impeller located in the housing and above the heater, and a motor configured to rotate the impeller, is described. The control method includes the actions of supplying washing water to the sump; rotating the impeller by supplying electricity to the motor; measuring an amount of electric current supplied to the motor during the rotating of the impeller; and heating washing water located in the housing by operating the heater based on the amount of electric current supplied to the motor during the rotating of the impeller being greater than or equal to a preset reference amount.

A control method of a dishwasher that includes at least two flow paths having different flow rates, a chamber having communication holes that each communicate with a respective flow path, a water supply pump configured to supply washing water to the chamber through an impeller rotated by a motor, and a flow path switching unit located within the chamber and configured to sequentially open the communication holes is described. The control method includes the actions of measuring an amount of current supplied to the motor while the motor rotates the impeller to supply washing water to the chamber, and determining a position of the flow path switching unit by comparing the amount of current supplied to the motor with reference current amounts that are each designated as an amount of current supplied to the motor when the motor rotates the impeller to supply washing water to the respective flow path.

Dishwasher and control method thereof

The present invention relates to a dishwasher and a control method thereof. According to one aspect, the dishwasher which washes dishes according to washing, rinsing, and drying steps comprises: a tub which is provided with a rack for accommodating dishes, and a washing nozzle for spraying washing water; a sump in which the washing water supplied to the tub is collected; a filter device which is provided to the sump, and allowing foreign substances of the washing water to be filtered; and a cleaning unit which clears away the foreign substances accumulated in the filter device.

Provided is a dish washer. The dish washer includes a tub configured to accommodate dishes, a sump configured to supply water to the tub, and a water supply device configured to supply water received from an outer source to the sump or the tub. The water supply device includes a body and a plurality of discharge parts. The body includes a water supply passage along which water supplied from an outer source flows and a water chamber in which water supplied through the water supply passage is stored. Water is discharged from the water supply passage to the water chamber through the discharge parts.
