System for coupling operating equipment to a washer

An easily repaired fluid handling device comprising:

• a large, stationary fluid system which receives fluid under pressure and returns spent fluid, the system including:
• an outer cosmetic housing;
• a plurality of spray nozzles for spraying the pressurized fluid;
• a stationary system first coupling portion;
• a stationary system second fluid coupling portion;
• plumbing permanently mounted to the system (i) for conveying the fluid under pressure from the first coupling portion to the nozzles and (ii) for returning the spent fluid to the second coupling portion;
• a trolley which is removably received within the outer cosmetic housing, the trolley including:
• a trolley frame which is supported on a plurality of casters;
• a series of fluid pumps, valves, and fluid tanks mounted to the trolley for receiving the fluid at a trolley fluid inlet and suppling the fluid under higher pressure at a trolley first fluid coupling portion;
• an electronic control circuit mounted to the trolley for controlling the pumps and valves;
• a first releasable coupling connecting assembly for fluidly connecting the trolley first fluid coupling portion and the stationary system first fluid coupling portion;
• a trolley second fluid coupling portion fluidly connecting with a trolley fluid inlet;
• a second releasable coupling connecting assembly for fluidly connecting the trolley second fluid coupling portion and the stationary system second fluid coupling portion;
• the trolley being selectively received in the cosmetic housing of the stationary system with the trolley and stationary system first and second fluid coupling portions fluidly connected during normal operation and being removed from the cosmetic housing by disconnecting the first and second releasable coupling connecting portions and rolling the trolley away from the device for easy access for maintenance and repair.

A method for coupling operating equipment to a washer which includes a washing chamber for receiving items to be washed and spray nozzles mounted in the washing chamber for spraying cleaning on the received items, the method including:

• mounting the operating equipment to a moveable trolleys the operating equipment including pumping equipment for pumping cleaning fluid to the washing chamber for washing the items;
• moving the trolley until it is adjacent an exterior wall of the washing chamber;
• connecting the operating equipment to the washing chamber with releasable couplings, including:
• coupling a first set of the releasable couplings to fluidly connect the pumping equipment with the washing chamber spray nozzles;
• and,
• pumping washing fluid from the trolley, through the releasable coupling to the spray nozzles, and washing the received items.
