  • Publication number: 20030041887
    Abstract: An improved pot and pan washing machine is provided including wash tank, a self-draining parallel flow pump connected to the wash tank, a self-cleaning intake manifold within the wash tank, flush mounted jet nozzles within the wash tank, and a non-welded field joint for connecting two portions of the washing machine together as a single unit. The pump is located on a side of the wash tank. Fluid enters the pump in a first direction and is discharged in a second direction that is substantially parallel to the first direction. The discharge fluid is unobstructed as it enters an outlet manifold located along the rear wall of the wash tank. Directional tubes of the nozzles then divert the fluid from the outlet manifold into jet streams that are directed towards the bottom wall of the wash tank. The jet streams skim across the top of the intake manifold to blow away debris.
