A dishwasher is provided, in which a plurality of filters are modularized to extend their effective area and improve their efficiency. The dishwasher includes a tub formed at an inside of the cabinet, forming a washing space where the dishes are washed; and a sump assembly provided at a lower side of the tub and provided with a filter chamber to which a filter module is inserted. The filter module filters the washing water, and includes a plurality of drainage filters.

Dishwasher

The present invention relates to a dish washer in which a structure for mounting a drain pump is improved for minimizing residual water, vibration and noise. The dish washer includes a cabinet which forms an exterior of the dish washer, a tub in the cabinet to form a space for washing the dishes, a sump assembly at a lower portion of the cabinet, the sump assembly having a drain chamber for holding washing water to be drained, and a drain pump assembly coupled to a lower side of an outside of the sump assembly so as to be in communication with one side of the drain chamber for draining the washing water from the drain chamber by pumping, wherein the drain pump assembly is mounted tilted upward at a predetermined angle from an inside bottom surface of the cabinet.

Dish washer

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.

Controlling method of dishwasher

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.

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.

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 () for washing dishes, a fan () for discharging air from the washing chamber (), a housing for a space to install the fan (), an exhaust duct () for guiding the air from the housing () to an outside of the dish washing machine, and a passage for draining water to an outside of the housing () whenever the water is present in the housing ().

Dish washing machine

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.

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.

Sump for dishwasher

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.

Dishwasher and sound-insulation member therefor

A dishwasher and controlling method thereof are disclosed, by which noise generated from rotation of a passage switching valve can be reduced in a manner of adjusting a rotation timing point of the passage switching valve and a rotation speed of a wash pump. The embodiments describe rotating a passage switching valve for switching a passage to selectively supply water to either an upper nozzle or a lower nozzle and reducing a rotational speed of a wash pump supplying the water to the upper and lower nozzles before the rotation of the passage switching valve.

Dishwasher and controlling method thereof

A method of controlling a dish washing machine capable of automatically washing items to be washed is disclosed. The method includes performing a steam spraying action defined to spray stream on a plurality of racks containing items to be washed, initiating a first water spraying action defined to spray on at least one first rack which is exposed firstly to the stream, and initiating a second water spraying action defined to spray water on at least one second rack, different from the first rack, wherein spraying water on the first rack begins prior to spraying water on the second rack.

Method of controlling a dishwashing machine having a steam generator

A dishwasher includes a tub, a steam generator for generating steam, a water supply passage for supplying washing water to the steam generator, a release valve having a steam passage along which the steam generated by the steam generator is supplied to the tub, and a condensed water passage connected to the water supply passage to allow water condensed by the steam to fall to the water supply passage.
