ABSTRACT:
A commercial dishwasher having a wash/rinse compartment for receiving dishes and a tank below the compartment for receiving wash or rinse water after a motor driven impeller has circulated the water from the tank and has forced it through spray arms in the compartment employs the suction created by the impeller for removing a detergent from a container in timed sequence by an entraining action during the wash cycle and mixing the detergent with the wash water during the dishwashing cycle. This same suction created by the impeller is employed for simultaneously removing a sanitizing liquid from a container and a rinse aid liquid from another container and mixing these two liquids with a rinse water during the rinsing and sterilizing cycle in timed sequence.
