Abstract
A cleaning chemical dispenser is provided. The dispenser includes bowl assemblies accommodating inverted containers with solid cast cleaning chemicals. The chemical dispenser generates cleaning chemical solutions by spraying a solvent such as water onto the solid cast concentrates. Concentrates from two of the containers are blended together, but are kept separate from the concentrate from the other container. All concentrate solutions are then further diluted in a venturi containing separate paths for each of the blended and separate solutions. The diluted solutions are then separately routed to the use container.
