Abstract: A washing machine including a washing tub to allow enhancement in washing efficiency. A washing tub of the washing machine includes a pattern having a protrusion portion to generate friction force between laundry and the washing tub and to thereby increase washing efficiency. The pattern has a concave-convex structure and performs action similar to a lifter, washing efficiency may be enhanced using tumbling generated by the pattern. A plurality of drain holes are arranged in a certain pattern in the washing tub to prevent a dehydration bottleneck phenomenon in which dehydration is concentrated at a particular drain hole and to increase a dehydration rate. The pattern is provided such that protrusion portions and recessed portions continue on the surface of the washing tub to enhance stiffness of the washing tub.

Abstract: A refrigerator, according to one embodiment, includes an inner case with an improved structure. The inner case includes a plurality of plates forming faces of the inner case, and one or more frames disposed between the plurality of plates to support the plurality of plates. The plates and the frames may be molded separately, without being molded as one body, so that the plates and the frames can be formed with various materials.

Abstract: Provided is a washing machine that can maintain sufficient rigidity while reducing a thickness of a frame by improving the shape of beads disposed at the frame, the washing machine including: a cabinet; a tub that is disposed to accommodate washing water in the cabinet and has a fastening hole formed in a rear side of the tub; a tub fixing part that is provided in plural numbers at a rear side of the cabinet in a position corresponding to the fastening hole; a fixing member that is inserted into the tub fixing part and is fastened to the fastening hole so that the tub is fixed to the rear side of the cabinet; and beads that are provided in plural numbers at both sides of the cabinet so as to have a shape of grooves formed in a direction of an inner side of the cabinet.

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. The through-holes are uniformly located around the protrusion, thereby preventing a spin dry water bottleneck phenomenon that occurs when water from a spin dry is concentrated on a certain through-hole, and thus enhancing the spin dry efficiency.
