[0008] When you need to replace a different type of spray arm group, first take out the bowl basket in the dishwasher's inner tank, then remove the entire spray assembly on the bowl basket separately, and then rotate and remove the fastening nut from the external thread area of ​​the spray arm connecting column. You can then remove the old spray arm group connected to the spray arm connecting column and replace it to adapt to different washing scenarios, greatly improving the user experience.

[0009] Preferably, annular ribs are provided at the ends of the connecting post through-hole, and the spray arm connector and fastening nut are respectively connected to the annular ribs at both ends of the connecting post through-hole. The linear contact of the annular ribs reduces the friction area, making the spray arm assembly more flexible and providing better sealing.

[0010] Preferably, the fastening nut is provided with a connecting ring groove on the side facing away from the spray arm assembly, within which a sealing ring is installed. This connecting ring groove design facilitates installation of the spray assembly within the inner tank. The sealing ring seals the spray assembly's mounting point, effectively preventing wash water leakage, ensuring wash water flushing pressure, and improving the cleaning effect.

[0011] Preferably, the spray arm assembly has a water cavity disposed therein, the water cavity communicating with the through-hole of the connecting post. An axial flow guide groove is disposed on the sidewall of the spray arm connecting post, the axial flow guide groove being located inwardly of the externally threaded region, and the through-hole of the connecting post and the axial flow guide groove communicating with each other. External wash water can flow sequentially through the axial flow guide groove and the through-hole of the connecting post into the water cavity of the spray arm assembly, and then be sprayed out through the spray nozzle on the surface of the spray arm assembly to wash dishes.

[0012] Preferably, the bowl basket is provided with a U-shaped limit frame matching the spray arm connector, and the U-shaped limit frame is composed of two mutually symmetrical vertical limit rods and a horizontal limit rod, the vertical limit rod includes rod segment one and rod segment two, the rod segment two is located between rod segment one and the horizontal limit rod, the rod segments one of the two vertical limit rods are parallel to each other and the distance between them is greater than the width of the spray arm connector, vertical limit grooves are provided on the side walls on opposite sides of the spray arm connector, the rod segments two of the two vertical limit rods are parallel to each other and the distance between them is adapted to the distance between the bottom surfaces of the two vertical limit grooves, and the side walls of the spray arm connector are also provided with horizontal limit grooves matching the horizontal limit rods. During installation, first place the spray arm connector between the two rod segments 2. Then, align the vertical stopper slot on the spray arm connector with rod segment 1 and insert it along rod segment 1 until the transverse stopper rod snaps into the transverse stopper slot. This completes the installation of the spray arm connector on the bowl basket. The structure is simple and easy to operate. The joint positioning of the vertical and transverse stopper rods greatly improves the installation stability of the spray arm connector.

[0013] Preferably, the connection between the first and second rod sections is smoothly rounded, which improves structural stability, avoids stress concentration, and makes the installation process of the spray arm connector more convenient and smooth.

[0014] The beneficial effects of the utility model are: it can adapt to different washing scenarios, greatly improving the user experience; disassembly and assembly are more flexible, and the sealing is good; it avoids leakage of washing water, ensures the flushing pressure of washing water, and improves the cleaning effect of washing; it has a simple structure and is easy to operate; it improves installation stability; it improves structural stability and avoids stress concentration; the installation process is convenient and smooth.
