  • Publication number: 20140096570
    Abstract: A washing machine including a drum capable of improving washing efficiency is provided. The washing machine includes a body, a tub provided at an inside the body to store wash water, a drum rotatably provided at an inner side of the tub to accommodate laundry, a driving apparatus to rotate the drum, protrusions that are formed of polygons having polygonal shapes and protruding inward from the drum, and a through-hole provided between adjacent protrusions to drain water. A protrusion having polygons generates frictional force between laundry and the drum, thereby increasing the washing power.

  • Patent number: 8529224
    Abstract: A hermetic compressor for adjusting the length and cross sectional area of a communication path as a refrigerant flow passage, so as to attenuate a discharge pulsation and consequently, a vibration and noise thereof. The hermetic compressor, which includes a cylinder head having a discharge chamber to discharge a compressed refrigerant and a discharge muffler to receive the refrigerant discharged from the discharge chamber, further includes a communication path to communicate the discharge chamber and the discharge muffler with each other, so as to allow the refrigerant to flow from the discharge chamber into the discharge muffler, and an auxiliary communication tube to increase a length of the communication path for increasing a refrigerant flow distance. The auxiliary communication path reduces the cross sectional area of a refrigerant flow passage while increasing a refrigerant flow distance, thereby attenuating a low-frequency component of the discharge pulsation.
