A method for controlling a dishwasher includes: supplying washing water to a sump; rotating an impeller disposed in a washing pump by a washing motor so that the washing water flows into the washing pump from the sump; operating a heater disposed in the washing pump so as to heat the washing water existing in the washing pump and generate steam to supply to a steam nozzle; and supplying the washing water or steam in the washing pump to the steam nozzle by rotating the impeller at a second set rotational speed lower than a first set rotational speed by the washing motor. The method further includes closing a selector valve, configured to open and close a path between the washing pump and the steam nozzle, when the impeller rotates at the first set rotational speed or higher.

Dishwasher and controlling method therefor

A dishwasher () is disclosed. The dishwasher () includes a washing tub () for defining a washing space, a rack () provided in the washing tub () so as to be withdrawn from the washing tub () for receiving dishes, and a plurality of spraying units () for spraying wash water to the rack (). The rack () includes an outer edge rib () for defining a space in which dishes are loaded, a variable space loading unit () upwardly and downwardly movably provided at the inside of the outer edge rib (), and a lifting unit () provided at the outer edge rib () for upwardly and downwardly moving the variable space loading unit () to decrease and increase the loading space of the variable space loading unit ().

Rack and dishwasher including the same

A dishwasher () is disclosed. The dishwasher includes a washing tub () for defining a washing space, a rack () provided in the washing tub () so as to be withdrawn from the washing tub () for receiving dishes, and a plurality of spraying units (), for spraying wash water to the rack (). The rack () includes a receiving box () having a loading unit () on which dishes are loaded and a turnable withdrawal unit () coupled to the loading unit () in a state of being in contact with the loading unit () so as to be turned upward for separating the dishes, loaded on the loading unit (), from the loading unit () when turned.

A method of controlling a dishwasher includes washing an object accommodated inside a tub by spraying water and detergent onto the object, rinsing the object by spraying water onto the object, drying the object by removing moisture adhered to the object, detecting an amount of a rinsing agent, comparing the detected amount of the rinsing agent to a predetermined amount, based on the comparison, determining whether the detected amount of the rinsing agent is less than the predetermined amount, and increasing at least one of a temperature of water to be supplied in the rinsing or a drying time in the drying based on determining that the detected amount of the rinsing agent is less than the predetermined amount.

Control method for dishwasher by detecting rinsing agent

Disclosed are a dish rack and dishwasher having the same. The present invention includes a wash tub forming a wash space, a rack configured to store a dish by being drawably provided within the wash tub, and a plurality of spray units configured to spray water upon the rack, wherein the rack comprises a frame configured to store a dish, a moving roller unit coupled with the frame to move upward and downward, the moving roller unit supporting a guide rail to draw the frame, and a location adjusting unit coupled with the frame, the location adjusting unit configured to selectively fix an upward/downward movement of the moving roller unit and release a fixed state of the moving roller unit to enable the upward/downward movement of the moving roller unit.
