Because the bowl basket may need to be height-adjustable during use, or in order to facilitate the removal of cutlery from the bowl basket, the bowl basket needs to be removed from the tub, and therefore, a movable connection is required between the spray arm and the water supply pipe.

As disclosed in chinese patent publication No. CN201820365541.8 (publication No. CN 209252763U), the connection structure of a spray arm pipeline and a dish washer includes a movable assembly for being disposed on a bowl basket and a fixed assembly for being disposed on a side wall of a bowl washing tank. The movable assembly comprises a water outlet pipe and a movable joint arranged at one end of the water outlet pipe, the movable joint is provided with a first inclined plane, the fixed joint is provided with a second inclined plane and a water inlet channel, and the water inlet channel is axially communicated with the water outlet pipe. The movable joint is connected with the fixed joint through the plug-in structure, when the plug-in structure is plugged in, the first inclined plane is matched with the second inclined plane, and the water outlet pipe is communicated with the water inlet channel. When the user puts forward the bowl basket perpendicularly to the sink, movable assembly and bowl basket are put forward together, and when the user placed the bowl basket, jack in the movable assembly can buckle the spliced pole in the fixed subassembly, and movable joint and fixed joint have adopted the mode contact of inclined plane, can reduce user's maloperation to make the pipeline connection good.

This is applicable to the manner in which the bowl basket is vertically lifted or lowered into the sink, and because the plumbing connection is provided on the bowl basket, the plumbing connection is also lifted or lowered into the sink in the same manner.

Or as shown in the 'water distribution structure, inner water pipe structure and dish washer' disclosed in the Chinese patent publication No. CN202121506706.7 (publication No. CN 215191361U), the side wall of the water outlet end of the inner water pipe is provided with a water outlet, the water distribution structure comprises a ball storage groove which is arranged on the inner water pipe and is positioned above the water outlet, the outer side of the ball storage groove is of a closed structure, the water distribution ball is configured to move between the ball storage groove and the water outlet and can move from the position of the water outlet to the inside of the ball storage groove under the action of water pressure, and move from the ball storage groove to the water outlet when the water pressure at the water outlet drops, and the water outlet is closed under the action of the water pressure.

The method is only suitable for the horizontal butt joint of the water pipe joint and the inner water pipe.

From the above, the current connection mode of the water pipe joint connected with the spray arm and the inner water pipe is either butt joint with the inner water pipe after moving in the vertical direction or butt joint with the inner water pipe after moving in the horizontal direction, and the bowl rack and the spray arm connecting pipe connected with the bowl rack are all moved outside the tank body, so that the space for placing the bowl rack is required to be specially arranged, and the spray arm connecting pipe connected with the bowl rack is also positioned outside the tank body, which is inconvenient.
