Abstract
A dish washing machine having upper and lower spray assemblies with separate spray arms and separate water supplies for washing and rinsing dishware. A spray base for each spray assembly segregates recycled wash water from clean incoming rinse water. A hollow drum mounted to each manifold has side discharge openings. A ball bearing assembly mounts the wash spray arms for rotation about the drums. A conduit for the rinse water extends through each drum and connects with a spindle on which the rinse spray arms are mounted for rotation. The upper and lower spray arm assemblies are interchangeable. The bearing assembly is uniquely constructed such that it is automatically flushed with clean rinse water during each cycle of operation.
