A device for drying and polishing a plurality of items including glasses and cutlery is provided. The device includes a plurality of movable cleaning elements configured to at least one of dry and polish the items and an enclosure defining a chamber, the movable cleaning elements being within the chamber. The enclosure includes a first aperture at a first enclosure location, a second aperture at a second enclosure location, a third aperture at a third enclosure location, and a channel assembly located in the chamber. The first aperture is adapted to receive a first item, the second aperture is adapted to receive a second item, and the third aperture is adapted to enable the second item to exit the chamber. The channel assembly defines a channel path between the second aperture and the third aperture.

A dishwasher and method utilize one or more sprayers to generate steam within a wash tub of a dishwasher by directing one or more sprays of fluid onto a heating element disposed in the wash tub of the dishwasher.

Disclosed is a control method of a dishwasher (100) including a tub (2) for receiving objects to be washed, a plurality of spray arms (711, 713, 715) for spraying wash water to the objects, and a steam nozzle (42) for spraying steam to the objects, the control method including a main washing cycle of washing the objects, a rinsing cycle of rinsing the washed objects using wash water, and a drying cycle of drying the objects after the rinsing is completed, wherein the drying cycle includes spraying steam, received from a steam source, to the objects to increase a temperature of the objects (a steam spraying step) and resupplying water to the steam source in order to prevent the steam source from being heated after the steam spraying step (a cooling step).

Disclosed is a washing pump for spraying washing water or steam to wash dishes or cooking appliances, and a dishwasher including the same. The washing pump according to the present invention includes: a housing; a partition wall which is vertically divides an inner space of the housing; an impeller which is rotatably disposed over the partition wall in the housing to cause washing water to flow; a heater which is disposed under the partition wall to heat the washing water in the housing so as to generate steam; and a steam discharge pipe which is disposed over the partition wall to discharge the steam, generated by the heater, to an outside of the housing. Accordingly, steam may be generated by the heater and discharged.

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.

A dishwasher includes: a case; a tub; a door; a sump disposed below the tub and configured to store washing water; a spray nozzle configured to spray washing water into the tub; a heater configured to heat washing water and generate steam; a steam nozzle disposed at the door or the tub and configured to discharge steam to the tub; a first rack disposed in the tub and configured to receive a washing target to be washed by washing water sprayed from the spray nozzle; and a second rack disposed in the tub and configured to receive a washing target to be washed by steam supplied from the steam nozzle. The steam discharged from the steam nozzle is supplied to an inside of the second rack through one of a lower surface or a circumferential surface of the second rack.

A dishwasher according to an embodiment of the disclosure includes a main body, a tub disposed inside the main body, having a washing chamber formed therein, and having an opening at a front side thereof, a basket configured to be rotatable in a first or second direction inside the tub, a driver configured to supply power to rotate the basket, and a door configured to be rotatable in the first direction based on a rotation of the basket in the first direction so as to open or close the opening of the tub.

Disclosed in the present invention are an energy-saving dishwasher and a control method therefor. The inner container is arranged inside the housing, the inner container is internally provided with a manifold type dish rack for placing dishes and spraying steam to perform steam cleaning on the dishes, and the manifold type dish rack is placed on a supporting frame fixed to the inner container. A water storage tank, a steam/hot water integrated generating device and a water pump are arranged below the inner container, and the steam/hot water integrated generating device includes a generating assembly and a control assembly. The manifold type dish rack is configured to place the dishes and simultaneously sprays steam to clean the dishes. The steam/hot water integrated generating device is configured to generate steam and hot water, heating is performed to generate the steam, and then relative cooling is performed to generate the hot water.

The present disclosure relates to a method of controlling a dishwasher. The method of controlling a dishwasher of the present disclosure includes steps of: detecting a temperature of air supplied to a tub through a heating duct by a temperature sensor; operating a supply fan which supplies outdoor air to the heating duct; operating a heater disposed in the heating duct; determining whether the supply fan and the heater are normally operating; and determining that the supply fan and the heater are normally operating, when a temperature change detected by the temperature sensor is within a first set range.
