It can be understood that the ball storage groove 102 is located above the water outlet 101, and the ball storage groove 102 and the water outlet 101 can also be located at two opposite sides of the inner water pipe 100, so that the normal operation of the dishwasher can be ensured when the upper basket is taken out.

In one embodiment, referring to fig. 2 to 4, the water distribution structure further includes a plurality of guide rails 121, the plurality of guide rails 121 are spaced apart from each other on the inner wall of the water outlet end of the inner water pipe 100, and the guide rails 121 are arranged along a vertical direction, that is, the arrangement direction of the guide rails 121 is parallel to the vertical direction. The guide rails 121 are arranged to provide a guiding function for the movement of the water distribution ball 400, and the space between the guide rails 121 can be passed by water flow to enter the top spray arm water pipe 300, so that top spray washing is not influenced. When the water-saving ball storage device is used, one section of the inner water pipe 100 with the water distribution structure is generally arranged along the vertical direction, and the corresponding guide rail 121 in the inner water pipe 100 is also arranged along the vertical direction, so that the gravity direction of the ball storage groove 102 is downward along the vertical direction, and when the water pressure rises, the thrust of water overcomes the gravity of the ball storage groove 102 to push the ball storage groove 102 to move upwards; when the water pressure drops, the ball storage tank 102 moves downward under the action of gravity. And the guide rail 121 is disposed along the length direction of the inner water pipe 100 when assembling or manufacturing.

In one embodiment, the upper and lower ends of the guide rail 121 are respectively provided with an arc-shaped section, and the arc-shaped sections at the upper and lower ends of the guide rail 121 form a limiting part, so that the water distribution ball 400 can move into the water outlet 101 or the ball storage groove 102 to provide guidance for accurate movement of the water distribution ball 400, and the limiting part also limits the water distribution ball 400 to move back and forth in the water distribution structure and not to fall out of the water distribution structure.

In one embodiment, the arc segments at the upper and lower ends of the guide rail 121 are an upper arc segment 122 and a lower arc segment 123, respectively.
