    摘要： A dishwasher (10) for treating dishes according to an automatic cycle of operation includes a tub (14) at least partially defining a treating chamber (16) with an access opening (18). A closure (20) selectively closes the access opening (18). At least one dish rack (32, 34) is located within the treating chamber (16). At least one rotating spray arm (150) is located within the tub (14), adjacent to and emitting fluid into the at least one dish rack (32, 34). The at least one rotating spray arm (150) includes a body (160) having at least one fluid spray opening (151); and
    at least one blade (170, 175, 180, 185) integrally formed with and extending laterally outwardly from the body (160) such that the at least one blade (170, 175, 180, 185) extends upwardly or downwardly from the body (160).

    摘要： A spray arm assembly (1000) and a washing appliance provided with same. The spray arm assembly (1000) comprises an upper spray arm (100) and a lower spray arm (200), the upper spray arm (100) being connected to the lower spray arm (200) and being located above the lower spray arm (200); and further comprises a first ball assembly (300), wherein the first ball assembly (300) is arranged at a position where the upper spray arm (100) is connected to and cooperates with the lower spray arm (200); and the upper spray arm (100) is rotatable relative to the lower spray arm (200). The hydrodynamic loss caused by using a connection method in a sliding friction manner in the prior art is reduced by means of the first ball assembly (300), and the smoothness during rotation of the upper and lower spray arms (100, 200) can be improved, and the noise can also be reduced.
