Description

[Technical Field] The present invention relates to a washing machine, and more particularly, to a washing machine including a filter device that prevents mold from being generated. [Background Art] Washing machines are machines that wash clothes using electric power, and generally include a tub configured to store washing water, a spin basket rotatably installed in the tub, and a pulsator rotatably provided at a bottom of the spin basket. When the spin basket and the pulsator are rotated in a state in which laundry and detergent are put into the spin basket, the pulsator agitates the laundry put into the spin basket with the washing water to remove contaminants from the laundry. In this process, a filter provided in the washing machine filters out foreign substances contained in the washing water and prevents the foreign substances from being mixed with the laundry again. In addition, the washing machine may include a body in which the filter is accommodated, and a cover provided on an outside of each of the body and the filter to improve corrosion resistance and aesthetic appearance. However, as the washing machine continues to be used, mold, scale, and the like may be generated between the cover and the body due to the washing water and the foreign substances, and thus there is a need for preventing the generation of the mold and the scale. US 2009/229319 A1, KR 2017 0123599 A and CN 206 308 502 U are directed to washing machines including a filter coupled to an inner wall of a washing tub. [Disclosure] [Technical Problem] Therefore, it is an aspect of the present invention to provide a washing machine capable of preventing mold and scale from being generated between a body and a cover.

The body further includes a body discharge hole formed in the first side of the body, the cover includes a cover discharge hole corresponding to the body discharge hole, and the sealing member includes a hole corresponding to the body discharge hole and the cover discharge hole so that the washing water flowed through the path is discharged into the spin basket through the body discharge hole, the cover discharge hole, and the hole. The body may include an edge protrusion protruding at least either upward or downward from an edge portion of the body, and the sealing member may include a recessed part recessed inward from an outer periphery of the sealing member so as to correspond to the edge protrusion. The edge protrusion may include a first edge protrusion protruding upward from a lower edge of the body, and a second edge protrusion protruding downward from an upper edge of the body. The sealing member may include a coupling protrusion protruding toward the body from an outer periphery of the sealing member so as to be coupled to the body, and the body may include a coupling hole formed to correspond to the coupling protrusion so that the coupling protrusion is inserted into the coupling hole. The cover may include a forming rib protruding toward the sealing member and forming the cover discharge hole, and the forming rib may be disposed in the hole of the sealing member sealing a space between the cover and the sealing member. The body includes a protective protrusion forming the body discharge hole and protruding closer to an inside of the spin basket than the cover to protect the cover from clothes. The body may include first body including the first side, and a second body including the second side coupled to the inner wall, and a second cover disposed between the first body and the second body and covering the second body, the cover may include a first cover to cover the first body, and the sealing member may be a first sealing member sealing a space between the first cover and the first body and a second sealing member sealing a space between the second cover and the second body.
