[0050] Furthermore, the plurality of first channels 610 are distributed inside the rotating sleeve 600 in an inverted funnel shape, and the top of each of the plurality of first channels 610 is connected to the confluence port 620, such as Figure 2 As can be seen from the water flow path shown by the middle dotted line, this setting can improve the convergence effect, reduce the flow resistance of clean water, reduce energy loss, make the dishwasher more energy-saving and environmentally friendly, while improving the cleaning performance and bringing a better experience to users.

[0051] Alternatively, if Figure 1-Figure 2 As shown, the spray arm assembly 200 includes a first spray arm 210, on which a first connecting pipe portion 212, a first flow channel 213 and a first spray hole 211 are provided. The bottom inlet of the first connecting pipe portion 212 is connected to the confluence port 620, the top of the first connecting pipe portion 212 is connected to the first flow channel 213, and the first spray hole 211 is connected to the first flow channel 213, so that the distribution and spraying of water flow can be more finely controlled to ensure that the water flow is evenly sprayed onto the surface of the tableware.

[0052] Alternatively, if Figure 1-Figure 2 As shown, the spray arm assembly 200 also includes a second spray arm 220, on which a second connecting pipe portion 222, a second flow channel 223 and a second spray hole 221 are provided.

[0079] Alternatively, if Figure 9-10 As shown, when two spray arm assemblies 200 are included, the rotating sleeves 600 connected to the two spray arm assemblies 200 are respectively a left rotating sleeve 600 and a right rotating sleeve 600, the left rotating sleeve 600 is rotatably connected in the left spray seat 100, and the right rotating sleeve 600 is rotatably connected in the right spray arm seat; the dishwasher includes a water supply assembly 700, the water supply assembly 700 includes a water cup 710, a washing motor 720 and a water diversion valve 730, water flows into the water cup 710, and after water is absorbed and discharged by the washing motor 720, it is divided into two water paths, the first water path enters the lower spray arm connecting pipe of the left spray seat 100, and then enters the left The washing water is then passed through the left spray arm assembly 200 and the left spray arm assembly 200 sprays the washing water. The second water path passes through the water diverter valve 730, and passes through the water diverter valve 730 connecting pipe, the lower connecting pipe of the water diverter valve 730, and the right spray seat 100 connecting pipe to enter the right spray seat 100, and then passes through the right rotating sleeve 600 to enter the right spray arm assembly 200, and finally sprays out from the right spray arm assembly 200. At this time, the washing area formed by the left spray arm assembly 200 and the right spray arm assembly 200 is wider, which can further improve the cleaning efficiency.

[0080] It should be noted that, because the water diverter valve 730 has the function of diverting water, when the valve core inside rotates to different positions, the water path has different flow directions. The water diverter valve 730 provided in this embodiment has two water path directions, one of which is that the water flow after coming out of the water diverter valve 730 flows in sequence through the water diverter valve 730 connecting pipe, the water diverter valve 730 lower connecting pipe, the right spray seat 100 connecting pipe, enters the right spray seat 100, passes through the right rotating sleeve 600, enters the right spray arm assembly 200, and finally sprays out from the right spray arm assembly 200. The other water path flows from the water diverter valve 730 through the upper connecting pipe of the water diverter valve 730 to other spray arm assemblies 200, so by selecting different water paths, the best regional washing effect can be achieved.

[0081] Alternatively, if Figure 8-Figure 10As shown, in this embodiment, the structure of the left spray arm assembly 200 is the same as that of the right spray arm assembly 200. The structure of the left spray arm assembly 200 is taken as an example for description, and the structure of the right spray arm assembly 200 is not repeated. The first spray arm 210 in the left spray arm assembly 200 includes a first spray arm body, a first flow channel 213 is opened inside the first spray arm body, and a plurality of first spray holes 211 are provided on the first spray arm body along the length direction of the first spray arm body. The second spray arm 220 includes at least one second spray arm body, and the second spray arm body is rotatably arranged at one end of the first spray arm body. A second flow channel 223 is provided in the second spray arm body along the length direction of the second spray arm body, and a plurality of second spray holes 221 are provided on the upper part of the second spray arm body. The second spray holes 221 are connected with the first flow channel 213 through the second flow channel 223, and the first flow channel 213 is connected with the first channel 610 on the rotating sleeve 600 in the spray seat 100 through the first connecting pipe portion 212, and then connected with the water source through the above-mentioned connecting pipeline, so that when the first spray arm body and the second spray arm body rotate, the first spray hole 211 and the second spray hole 221 spray out the cleaning area overlapping, thereby improving the cleaning effect.

[0082] Preferably, the second spray arm 220 includes three second spray arm bodies, and the three second spray arm bodies are evenly spaced along the circumferential direction of the second spray arm 220, that is, the angle between two adjacent second spray arm bodies is 60°, so as to form a trident-shaped second spray arm 220, which can make the spray area formed by the first spray arm 210 and the second spray arm 220 approximately rectangular, more suitable for the shape of the inner cavity of the dishwasher, avoid cleaning dead corners, and improve the cleaning effect. In other embodiments, the number of second spray arm bodies included in the second spray arm 220 is not specifically limited, and can be 4, 5, 6, etc.
