Abstract
A non-hazardous dispenser apparatus for converting powdered detergent, including those containing active chlorine, into a concentrated detergent solution for use by a washing machine. A curved screen member retainably supports a mass of powdered detergent thereabove within a generally cylindrical container configured for mounting to the side wall of a washing machine adjacent the detergent solution carrying reservoir thereof. A single spray-forming nozzle is mounted within the container and below the curved screen for directing a uniform spray of water at substantially the entire downwardly facing concave surface of the screen member. Only that detergent carried immediately above the screen member is wetted by the spray and passes in solution through the screen, after which it is collected and directed by a collecting portion of the container, into the washing machine reservoir. Spray control means, either manual or electronic, controls the spray of water through the nozzle in response to the concentration level of detergent within the washing machine reservoir. The container is loaded through an upper access port normally closed by a door member. Safety switch means disables spray from the nozzle whenever the door member is open.
