Therefore, when the basket 60 (refer to FIG. 2) is inserted or withdrawn from the washing tank 12 (refer to FIG. 2), the ball 140 rolling along the first raceway 123a interferes with the drain hole 200. Noise can be prevented.

In addition, foreign matter or washing water accumulated in the first raceway 123a does not interfere with the ball 140 and may be smoothly drained through the drain hole 200.

The first end 210 may be vertical along the height direction of the washing tub 12. The second end 220 may be horizontal along the horizontal direction of the washing tub 12. However, it is not limited thereto.

The drainage hole 200 may be adjacent to the first raceway 123a rather than the second raceway 123b. That is, the drain hole 200 may be disposed outside the ball 140 rolling the raceway 123.

FIG. 8 is an enlarged view of “A” shown in FIG. 6 in a dishwasher according to another embodiment of the present invention. As shown in FIG. 8, the mid-rail 120 according to another embodiment of the present invention may include a support portion 121 and a drain hole 300 provided between the bent portion 122.

In the drain hole 300 according to another embodiment of the present invention, only the structure of the drain hole 200 (see FIG. 7) and the first end 310 according to the embodiment of the present invention is different, and the rest of the configuration may be the same. I can. Therefore, a description of the same configuration as the drain hole 200 according to an embodiment of the present invention may be omitted.

Hereinafter, a drain hole 300 according to another embodiment of the present invention will be described with a focus on the first end 310.

At least a portion of the drain hole 300 may be disposed at a corner of the mid-rail 120 where the bent portion 122 is bent from the support portion 121.

The first raceway 123a includes a first curved portion 124a on which the ball 140 rolls, and a second curved portion 124b extending from the first curved portion 124a and curved in a direction opposite to the first curved portion 124a. The branch may include a curved portion 124.

The drainage hole 300 may include a first end 310 in contact with the bent portion 122 and a second end 320 in contact with the support 121.

The first end 310 of the drain hole 300 according to another embodiment of the present invention includes the first curved portion 124a and the first curved portion 124a to smoothly drain the washing water accommodated in the first curved portion 124a from the first curved portion 124a. It may be disposed between the 2 curved portions 124b.

That is, the first end 310 of the drain hole 300 according to another embodiment of the present invention may be inclined. The first end 310 of the drain hole 300 according to another embodiment of the present invention is a first raceway from the first end 210 (refer to FIG. 7) of the drain hole 200 according to an embodiment of the present invention. It may be inclined toward the ball 140 rolling 123a.

The first end 310 may be configured to be in contact with the ball 140 rolling the first raceway 123a at one point. That is, the first end 310 may be disposed on an extension line in the radial direction of the ball 140.

Accordingly, it is possible to minimize interference with the movement of the ball 140 rolling along the first raceway 123a by the drainage hole 300.

In other words. The inclination of the first end 310 of the drain hole 300 may be inclined within a limit in which the motion of the ball 140 rolling along the first raceway 123a is not interfered by the drain hole 300.

As the first end 310 of the drain hole 300 according to another embodiment of the present invention is inclined, the volume may be larger than that of the drain hole 200 according to the embodiment of the present invention, so that the first raceway Foreign matter or washing water accumulated in (123a) can be drained more smoothly.

The second end 320 may be horizontal along the horizontal direction of the washing tub 12. However, it is not limited thereto.

Although the technical idea of the present invention as described above has been described by a specific embodiment, the scope of the present invention is not limited to this embodiment.

Various embodiments that can be modified or modified by a person of ordinary skill in the technical field of the present invention within the scope not departing from the gist of the technical idea of the present invention specified in the claims also belong to the scope of the present invention. will be.
