ABSTRACT:
A continuous-flow pot and pan washing system comprising a frame; a substantially rectangular tub mounted on the frame, where the side walls of the tub are shorter in length than the back and front walls of the tub; a pump mounted to the frame; a tub outlet channel coupled between the back wall of the tub and an inlet port of the pump, providing fluid communication between the tub interior and the pump; a manifold mounted to a first one of the sidewalls, having a manifold inlet coupled to, and a fluid communication with, the outlet port of the pump; and an array of outlet nozzles extending from the manifold, through the sidewall and into the tub interior, where a substantial portion of the outlet nozzles are angled towards one of the front or back walls such that the nozzles are adapted to jet fluid in a whirlpool-like manner substantially about the perimeter of the tub. Preferably the nozzle array includes nozzles positioned at least two vertical levels. This assures that at least two vertical portions of the tub interior experience the whirlpool-like turbulence. The washing tub also preferably includes rectangular recess extending into one of the tub walls to provide a substantially turbulent-free bay within the tub interior. A fluid level sensor and a heating element extend into the bay and operate without significant interference from the turbulence created by the nozzles. Because the heating element is recessed from, and screened off from, the effective area of the tub, a safer and larger effective washing area is provided.
