Abstract: A washing machine includes a housing; a drum disposed inside the housing and including a rotation shaft that extends in a vertical direction; and a filter unit disposed at an inner wall of the drum, configured to filter washing water flowing in a circumferential direction of the drum and to discharge the washing water in a radial direction inside of the drum. Accordingly, when a water current is formed inside the drum in the circumferential direction of the drum, the filter unit is disposed inside the drum so that foreign substances in the washing water rotated in the circumferential direction of the drum can be easily filtered.

Abstract: A washing machine comprises a housing, a drum rotatably disposed inside the housing, a driving shaft configured to transfer a rotational force from a driving motor of the washing machine to the drum, and a driving shaft flange configured to connect the driving shaft to the drum. The driving shaft flange comprises a first surface, a second surface substantially parallel to the first surface, wherein the first surface and the second surface are spaced apart from each other by a predetermined distance in the vertical direction, and an extension portion formed perpendicular to the first surface and the second surface and connecting the first surface to the second surface. An edge of the first surface and an edge of the second surface and an edge of the extension portion are substantially aligned in vertical direction of the drum.
