Abstract
A solid block chemical dispenser for cleaning systems. A substantially horizontal support screen within a housing retainably supports a solid block of wash chemical thereabove. The support screen divides the housing into an upper cylindrical storage portion and a lower funnel shaped collector portion. A spray forming nozzle is mounted within the collector portion below the generally horizontal screen for directing a spray of water at substantially the entire downwardly facing surface of the wash chemical block supportably retained above the support screen. The dissolved wash chemical passes through the support screen, is collected by the collector portion of the housing, and directed to its utilization point. Spray controls, either manual or electronic, control the spray of water through the nozzle in response to a control signal. The dispenser is configured for mounting to a vertical surface and is loaded through an upper access port normally closed by a door. A safety switch prevents the spray of water from the nozzle whenever the door is open.
