Abstract: Detergent dispenser for providing water-added, concentrated detergent solutions, particularly for replenishing the detergent reservoir of an automatic washing machine, comprising a container equipped internally with a horizontally disposed perforated plate for receiving detergent the plate dividing the container into an upper detergent retaining zone and a lower fluid reservoir zone. In operation, water is continually admitted to the reservoir zone through an inlet port and rises through the plate and detergent mass, thereafter exiting as a concentrated detergent solution via a discharge port positioned above the detergent retaining zone.
