Abstract: A desiccant replacing apparatus may include a supply-discharge member, a supply connection line connected to the supply-discharge member, an air conveyor coupled to the supply connection line, a discharge connection line connected to the supply-discharge member, and an air amplifier coupled to the discharge connection line. The supply-discharge member may include a housing providing an internal space, an injection line providing an injection path and penetrating the housing, an exhaust line providing an exhaust path connected to the internal space, and a filter in the internal space or the exhaust path. The supply connection line may be connected to the injection line, and the discharge connection line may be connected to the exhaust line.

Abstract: A dishwashing method of a dishwasher which includes a body, a dishwashing tub contained in the body, a steam generator received in the dishwashing tub to generate steam, a plurality of steam injection nozzles to inject the steam generated by the steam generator, a plurality of control valves to control flow of the steam into the respective steam injection nozzles, the method including injecting steam from a plurality of the steam injection nozzles comprising opening a plurality of the control valves, to maintain an injection pressure of the steam generated by the steam generator.

Abstract: A steam/water mixed dishwasher using steam and water together, and, more particularly, a dishwasher and dishwashing method of achieving improvement in washing performance and efficiency via direct steam injection to dishes. The dishwasher includes a body containing a dishwashing tub, at least one dish basket disposed in the dishwashing tub and adapted to receive dishes therein, a steam generator to generate steam by heating wash water, and steam injection nozzles to inject the steam generated from the steam generator. The steam injection nozzles are disposed at the same height as a lower surface of the dish basket. The dishwashing method includes injecting steam from a number of the plurality of steam injection nozzles by opening a number of the plurality of control valves, to thereby maintain an injection pressure of the steam generated from the steam generator.
