Among them, the filter mounting portion, the support shaft constituting the rotating shaft of the filter unit; And an opening formed at a rear side of the support shaft and communicating with the reflux channel. It includes. Further, a wall portion for preventing water from flowing out through the opening portion is formed on the surface of the channel forming member from the water channel forming member toward the inner circumferential wall side.

According to the above structure, since the water flowing in the reflux can flow into the filter unit well, the collection efficiency for the seams of the filter unit and the like can be improved.

In the washing machine of this embodiment, the said wall part can be comprised so that at least the lower side, the left side, and the right side of the said opening may surround three directions.

According to the above structure, it is possible to prevent the water that is directly sorted by hitting the wall below the wall part from flowing into the opening from the side, and further preventing the water from flowing out through the opening.

In the case of using the above structure, a gap can be formed between the wall portion and the inner circumferential wall.

With this structure, during the dehydration process, even if the water discharged from the laundry flows into the wall portion surrounding at least three directions of the opening, the introduced water can flow out into the reflux channel through the gap. Thus, water can be prevented from remaining inside the wall portion.

In the washing machine according to the present embodiment, the wall portion may be configured such that the central portion has a protrusion having a shape that protrudes further upstream of the reflux channel as compared with both ends in the left and right directions of the opening.
