Abstract: A method for controlling a dishwasher including the steps of first determining a steam operation mode for washing dishes and second determining at least one of a motor rotation speed, a number of repetitions of a steam supply step, a steam washing pattern, and an amount of detergent based on the determined steam operation mode.

Abstract: A water flow control device for an appliance includes a sump to collect water from a washtub, a supply passage to supply water from the sump to the washtub, a drain passage, coupled to the sump to discharge water; and a disposer to dispose contaminates in water from the sump. The disposer is in fluid communication with the drain passage but not the supply passage.

Abstract: A method for controlling a dishwasher includes sequentially performing a first main washing step, a second main washing step, and a third main washing step. The first main washing step includes supplying washing water, which is heated by a sump heater, to a washing chamber. The second main washing step includes selectively performing a steam spraying action for supplying steam to the washing chamber, and performing a water supplying action for supplying washing water to the washing chamber. The third main washing step includes supplying washing water, heated by the sump heater, to the washing chamber.

Abstract: The present invention relates to a dish washing machine, and more particularly to a dish washing machine having a structure in which a bottom surface of the dish washing machine is not wet with water. The dish washing machine includes a washing chamber (150) for washing dishes, a fan (90) for discharging air from the washing chamber (150), a housing for a space to install the fan (90), an exhaust duct (92) for guiding the air from the housing (94) to an outside of the dish washing machine, and a passage for draining water to an outside of the housing (94) whenever the water is present in the housing (94).

Abstract: The present invention relates to a dishwasher. A dishwasher includes a washing tub in which dishes are placed, a steam generator that generates steam and a nozzle part in which a flow direction of the steam is diverted at least one time to allow the steam exhausted to the washing tub.

Abstract: A dishwasher is disclosed, by which a manufacturing cost of the dishwasher can be reduced in a manner of reducing the number of pumps used for the dishwasher. The present invention includes a tub (1), a sump (20) provided under the tub (1) to store water, a wash passage (51) guiding the water stored in the sump (20) to the tub (1), a drain passage (52) guiding the water stored in the sump (20) to be discharged from the tub (1), a driving unit (10) provided tinder the sump (20), the driving unit (10) pumping the water after grinding garbage contained in the introduced water, and a passage switching valve (60) provided to a diverging portion between the wash passage (51) and the drain passage (52) to enable the water pumped by the wash pump to be selectively supplied to the wash passage (51) or the drain passage (52).

Abstract: A sump for a dishwasher includes a sump case for collecting washing fluid, a pump housing on the sump case, a filtering assembly provided on an upper portion of the pump housing, and a sealing member disposed around the pump housing. The pump housing is provided with a pump case therein.

Abstract: A dishwasher is provided which can reduce the discharge of noise produced by the dishwasher, thereby preventing a user from being upset due to the noise and achieving not only a comfortable use environment but also an improvement in productivity. With the dishwasher, it is possible to prevent the noise, caused during operation of the dishwasher, from being discharged from a lower side of a door, by use of a sound-insulation member with a simplified configuration. In the manufacture of the dishwasher, improved assembly productivity can be accomplished.
