Washing machine having drain casing

摘要

A washing machine filter having improved structures of a drain filter (30) and a drain casing (20) so that foreign substances are effectively eliminated from wash water, thereby making it less necessary to frequently clean the drain filter (30). The drain filter (30) includes a filter member (31) having filter holes (34) and filter protrusions (35), and a hand lever (32) rotatably connected to the front end of the filter member (31). The filter protrusions (35), having a length larger than the depth of the filter holes (34), are perpendicularly protruded upward from the surface of the filter member (31), and each of the filter holes (34) has a hexagonal shape. The drain filter (30) can be detachable from the drain casing (20) through a filter entrance (24) formed in the front surface of the drain casing (20). A guide plate (33) can be positioned at the rear end of the filter member (31), and a guide protrusion (24b) corresponding to the guide plate (33) can be formed at the filter entrance, thereby permitting alignment of the drain filter (30) within the drain casing (20).
