Mid-level spray-arm assembly |
摘要 |
A mid-level spray-arm assembly for a dishwasher includes a bracket for mounting a spray-arm hub to an upper rack of the machine, and a bearing coupling extending between the hub and the bracket. The bearing coupling forms a first bearing surface for rotation of the bearing coupling relative to the bracket, and a second bearing surface for rotation of the spray-arm relative to the bearing coupling. Thus, redundant bearing surfaces are provided that facilitate a more even wearing of the bearing surfaces and allow rotation of the spray-arm even when one of the bearing surfaces fails.
