There is provided a dishwasher. The dishwasher includes a tub for receiving dishes, a steam generation unit provided at an outside of the tub and generating steam that will be supplied to the tub, a steam passage along which the steam generated from the steam generation unit is supplied to the tub, and a chamber for storing water used for generating the steam.

Dishwasher

Disclosed is a dishwasher, which prevents a washing cycle from being carried out in an insufficient state of washing water caused by the continuous discharge of the washing water due to a siphon action, and a method of controlling the dishwasher. The method includes draining washing water from the dishwasher; supplying the washing water to the inside of the dishwasher; and temporarily stopping the supply of the washing water for a designated time between the drain of the washing water and the supply of the washing water.

Dishwasher and method of controlling the same

In the dishwasher and the control method therefor of the present invention, the turbidity of washing water is measured and, if it is decided that the level of dirtiness of the tableware is low, then the time over which a heater operates during the washing routine is reduced and, instead, the time over which the heater operates during the rinsing routine is increased. This is advantageous in that it can improve the performance of the drying which is carried out after the rinsing routine. Further, if it is decided that the level of dirtiness of the tableware is high, then the time over which the heater operates during the washing routine is increased and the time over which the heater operates during the rinsing routine is reduced. This is advantageous in that the washing performance can be improved while the overall heater operating time can be maintained.

Dishwasher and a control method therefor

A dishwasher is provided in which heights of basket(s) of a rack assembly may be easily changed. The dishwasher may include a frame configured to be inserted into and withdraw from a washing tub and plurality of basket positioning device configured to receive and support basket(s) at different heights.

Dishwasher and rack assembly therefor

A dishwasher is disclosed which includes a rack arranged inside of a washing cabinet, a plurality of shelves arranged on the rack, and a shelf holder installed on the rack. The shelf holder may include a plurality of shelf fixing parts that fix the shelves together. The dishwasher so configured is capable of minimizing the number of shelf holders needed to fix a plurality of shelves to a rack and, therefore, simplifies the assembly process.

Dishwasher having rack with shelf holder

A dishwasher and a method for controlling the same are provided. The dishwasher includes a contamination level sensor that measures a contamination level of washing water in a washing tub of the dishwasher. The method includes supplying washing water to an inside of the dishwasher, washing dishes by spraying the washing water to the inside of the dishwasher, temporarily pausing the washing of the dishes for a preset time period, and resuming the washing of the dishes after the preset time period.

Method for controlling dish washer

Dishwasher including a washing tub for placing dishes therein, a sump for accommodating washing water to wash the dishes in the washing tub, and a motor having a rotor and a stator, for generating pumping power to pump up the washing water from the sump to the washing tub, wherein the stator of the motor is wound in a concentrated winding type, thereby permitting effective utilization of the washing tub and the driving part room.

A dish washer includes a steam generating unit that is configured to control the amount of steam in accordance with the amount of items in the dish washer. The steam generating unit is positioned outside of the tub and is configured to generate and supply steam to the tub. The dishwasher includes a fluid supplying passage that supplies washing fluid to the steam generating unit. A steam discharging passage is configured to discharge steam that is generated from the steam generating unit to the tub.

Dish washer

A dishwasher is disclosed which includes a washing cabinet, a frame disposed within the washing cabinet, and a basket, which is placed on the frame, and whose height is adjustable by a back and forth movement. With this construction, there is no need to lift the basket, rotate it 90&#xb0;, and reposition the basket to adjust a height of the basket. Rather, it is possible to adjust the height of the basket by a simple operation of pulling the basket forward or pushing it rearward.

Dishwasher with adjustable basket(S)

A dishwasher includes a sump for receiving washing water, a washing pump for pumping the washing water from the sump, a drain chamber for receiving the pumped washing water, and a filtering unit disposed above the drain chamber. The filtering unit includes a contaminated water for receiving and filtering the washing water that has passed through the drain chamber.

The present invention provides a sump assembly of a dishwasher, by which water can be purified. The present invention includes a sump housing storing water therein, a pump coupled with the sump housing to pump the water, a guide assembly provided within the sump housing to guide the pumped water to a sprayer, and a drain chamber configured to filter contaminant from the water drained from the guide assembly.

Dishwasher and sump assembly thereof

A water recirculator in a dishwasher supplies water to spray arms for washing dishes and also purifies contaminated water after washing the dishes. The water recirculator includes a sump for holding water, a water supply pump connected to the sump, a guide passage for guiding a portion of the water pumped by the water supply pump to a spray arm in a washing chamber, a pre-filtering unit for purifying a rest of the water pumped by the water pumped by the water supply pump by means of precipitating contaminants included in the water therein, and a main filtering unit for purifying the rest of the water passed through the pre-filtering unit.

Water recirculator in dishwasher

Provided is an apparatus for controlling a washing flow of a dishwasher that can perform an upper washing, a lower washing, an alternate washing of upper and lower sides, and a concurrent washing of upper and lower sides for effective washing.

Apparatus for controlling washing flow of dishwasher

Dishwasher including a sump for holding washing water, a flow passage control valve mounted to the sump for controlling a flow direction of the washing water such that the washing water makes alternate washing, and a valve control device for controlling the flow passage control valve to be moved within a predetermined range of angle, thereby permitting an easy mounting of the flow passage control device which controls a flow direction of the washing water, and reduces waste of the washing water by alternately washing an upper part and a lower part.

A dishwasher is disclosed, including a sump for receiving wash water for washing contaminated dishes; a main motor for circulating wash water in the sump; a washing pump connected with the main motor and pumping the wash water; a main channel and a sampling channel formed in a drain direction of the washing pump; and a contamination sensor mounted at a channel extension part located at the sampling channel and measuring contamination of the wash water. The dishwasher of the present invention is able to measure contamination of wash water for washing dishes and to mount the contamination sensor for measuring the contamination of the wash water with ease.
