The co-operating arrangement of the annular flange 21 and the upper fitting 31 is to prevent water leakage and their function is to ensure that the sub-split piping 2 is tightly connected while being rotatable relative to the sub-water supply piping 3 and to prevent water from spilling or overflowing from the connection. In the prior art, the sub-split water supply pipeline 2 needs to rotate relative to the sub-water supply pipeline 3, and the sub-water supply pipeline 3 is generally an integral section and extends into the sub-split water supply pipeline 2, and as the sub-split water supply pipeline 2 needs to rotate relative to the sub-water supply pipeline 3, gaps are needed between the pipe walls of the sub-split water supply pipeline 2, so that a large amount of liquid overflows or overflows from the connection positions of the sub-split water supply pipeline and the sub-split water supply pipeline. The provision of an annular flange 21 prevents liquid from directly overflowing from the junction, so that liquid can only bypass the flange and then overflow or overflow from between the flange and the sub-water supply pipe 3, but if only the flange is provided, the gap between the sub-water supply pipe 2 and the pipe wall of the sub-water supply pipe 3 is enlarged, the radius of the sub-water supply pipe 3 must be increased at the part of the sub-water supply pipe 2, so that the radius of the part of the sub-water supply pipe 3 in contact with the annular flange 21 is smaller, the radius of the sub-water supply pipe 3 is larger at the part of the sub-water supply pipe 2, and thus the sub-water supply pipe 3 cannot extend into the sub-water supply pipe 2, and therefore, only the sub-water supply pipe 3 can be designed to be of a two-stage detachable design, the upper stage is movably abutted on the annular flange 21, and the lower stage is detachably connected to the lower end of the upper stage. The design can not only reduce the gap between the pipe walls of the sub-diversion pipeline 2 and the sub-water supply pipeline 3, but also prevent liquid from directly overflowing from the joint or overflowing, thereby achieving the effect of reducing the water-crossing phenomenon.

The clearance between the upper joint 31 and the sub-split pipe 2 is indeed to provide a certain space when the sub-split pipe 2 rotates relative to the upper joint 31, and the existence of this clearance allows the sub-split pipe 2 to rotate or swing within a certain range without generating excessive friction or resistance with the upper joint 31. The upper joint 31 is located inside the sub-split pipe 2, is movably sleeved in the sub-split pipe 2, and can also be taken out from the sub-split pipe 2 as a separate piece. The sub-split-flow pipeline 2 is provided with a plurality of water through holes 311, water in the sub-water supply pipeline 3 enters the sub-water supply pipeline 3 and then is discharged from the water through holes 311, and because the water through holes 311 and the second cleaning arm 9 are positioned on the same horizontal line, most of water discharged from the water through holes 311 directly enters the second cleaning arm 9 due to inertia, and only a small part of water can be remained in the sub-split-flow pipeline 2, so that water overflows from the joint of the sub-split-flow pipeline 2 and the sub-water supply pipeline 3 can be reduced.

The upper fitting 31 is a pipe located inside the sub-split pipe 2, and if necessary, the user can insert the upper fitting 31 into the sub-split pipe 2 and ensure firm connection and sealing.

Specifically, since the top end of the inner sub-pipe 322 directly discharges water, the top end and the water through hole 311 are positioned on the same horizontal line, so that the sprayed water enters the second cleaning arm 9 through the water through hole 311 to the greatest extent due to potential energy, rather than flowing into the sub-split flow pipe 2, and water overflow can be avoided to a greater extent.

In some embodiments of the present utility model, the internal thread 312 is provided below the water passage hole 311. In particular, such an arrangement ensures that the junction of the upper fitting 31 and the lower pipe 32 is located below the water passage 311, ensuring a tight connection of the upper fitting 31 and the lower pipe 32.

The annular boss 323 is positioned at the lower end of the internal thread 312 with respect to the outer wall of the lower pipe 32, and abuts against the annular flange 21, and this positional relationship ensures that the annular boss 323 can be effectively coupled with other components.

The arrangement of the annular boss 323 can provide stable connection and ensure the tightness of the water pipe, if the annular boss 323 is not arranged, liquid can directly pass through the gap between the annular flange 21 and the sub-water supply pipe to cause the phenomenon of water stringing, and the annular boss 323 is added, so that the liquid can only pass through the gap between the first water supply pipe and the sub-split flow pipe 2, then pass through the gap between the annular flange 21 and the first water supply pipe, and then pass through the gap between the annular flange 21 and the annular boss 323, and the gap is required to pass through the layer-by-layer gap, and each gap is furthest small, thus the occurrence of water leakage and leakage phenomenon can be effectively prevented, the reliability and the service life of the dish washer are improved, and in addition, the design of the annular boss 323 can simplify the assembly and maintenance process, so that the operation is more convenient.
