Abstract: A dishwasher that is provided with an improved soundproofing structure to reduce the manufacturing cost of the dishwasher and accomplish an improved soundproofing effect in comparison with conventional dishwashers. The disclosed dishwasher includes a washing tub provided in a cabinet. A basket is provided in the washing tub to hold dishes therein. A washing pump pressurizes wash water contained in the washing tub. An injection nozzle sprays wash water supplied from the washing pump. A soundproofing unit with a net structure is installed in the washing tub in such a way as to be spaced apart from the inner surface of the washing tub, thus dispersing wash water sprayed from the injection nozzle while reducing pressure of the wash water.

Abstract: A dishwasher includes a casing arranged within the dishwasher, an odor eliminating material installed within the casing, a shutter which selectively opens a part of the casing to expose the odor eliminating material, and a shutter driving device which operates the shutter. A control unit of the dish washer counts an actual drying time in a drying operation of the dishwasher, and opens the shutter by operating the shutter driving device in response to the counted drying time being equal to or greater than a preset drying time. The odor eliminating material eliminates odors in the dishwasher.
