Central header for liquid cleaning units

摘要

A washing chamber (10) is surrounded by corner manifolds (14) and interconnecting conduits (16) extending along top, bottom, and side walls of the washing chamber. The conduits have nozzles (12) therein for spraying washing and rinsing liquids into the washing chamber. A central header assembly (40) includes a conduit (42) extending from one of the headers to a terminal end adjacent a central plane of the washing chamber. The central header assembly includes a header (46) with a manifold portion (48) and a plurality of extending arms (50) with nozzles on opposite sides. The header manifold portion is connected with the terminal end of the conduit (42). In one embodiment, a pivotal fluid connection and valve (44) enables the header to pivot between a position in the vertical plane and a stowed position parallel to the top of the washing chamber. In another embodiment, a quick-connect coupler system (100) interconnects the header with an outlet at the terminal end of the conduit (42).
