Abstract:
A spray mechanism for use in conjunction with a glass washing and dishwashing machine having a washing zone, the spray mechanism comprising:a. an elongated hollow lower manifold mounted within and below said washing zone and having an inlet port and an outlet port;b. an elongated lower bracket mounted within and below said washing zone and located opposite to said lower manifold;c. a plurality of spaced apart hollow lower spray bars, each having a closed end, an open end rotatably connected to said lower manifold for allowing water to flow therethrough, and a plurality of spaced apart small bores for allowing water to spray out into said washing zone;d. a plurality of lower spring-loaded arms, each having a distal ball end, and a proximal end pivotably connected to said lower bracket and located adjacent to said closed end of said each lower spray bar;e. a lower driving shaft rotatably mounted within said washing zone and adjacent to said plurality of lower spring-loaded arms, the lower driving shaft having a plurality of spaced apart transverse zig-zag grooves therein, where said distal ball end of said each lower spring-loaded arm respectively engages with and travels along said each transverse zig-zag groove for oscillating said each lower spray bar;f. an elongated hollow upper manifold mounted within and above said washing zone and located parallel to and above said lower manifold, the upper manifold having an inlet port connected to said outlet port of said lower manifold by a first flexible conduit for supplying water thereto;g. an elongated upper bracket mounted within and above said washing zone and located opposite to said upper manifold;h. a plurality of spaced apart hollow upper spray bars, each having a closed end, an open end rotatably connected to said upper manifold for allowing water to flow therethrough, and a plurality of spaced apart small bores for allowing water to spray out into said washing zone;i. a plurality of upper spring-loaded arms, each having a distal ball end, and a proximal end pivotably connected to said upper bracket and located adjacent to said closed end of said each upper spray bar;j. an upper driving shaft rotatably mounted within said washing zone and adjacent to said plurality of upper spring-loaded arms, the upper driving shaft having a plurality of spaced apart transverse zig-zag grooves therein, where said distal ball end of said each upper spring-loaded arm respectively engages with and travels along said each transverse zig-zag groove for oscillating said each upper spray bar;k. an elongated cover member respectively installed over said each spray bar and having a channel with a plurality of spaced apart bores which are smaller than and aligned with said plurality of spaced apart bores of said each spray bar;l. a second flexible conduit connected to said inlet port of said lower manifold for supplying water to said upper and lower spray bars; andm. means for rotating said upper and lower driving shafts which in turn allow said distal ball end of said each spring-loaded arm to move along said each transverse zig-zag groove to oscillate said plurality of upper and lower spray bars;n. whereby said upper and lower spray bars oscillate to spray water into said washing zone for cleaning glasses and dishes therein.
