A solid block chemical dispenser for cleaning systems. The dispenser housing retainably supports a three-dimensional screen comprising: (i) a lower, substantially horizontal, circumferential support and extension portion in supportable contact with the housing and extending towards the central axis of the housing, (ii) a substantially vertical circumferential wall integrally coupled with the lower support and extension portion, the wall extending into the storage portion of the housing and defining a generally longitudinal elongated torroidal cavity between the housing and the wall, and (iii) a substantially flat, horizontal top portion integrally coupled with the wall for supporting the block of chemical thereabove. A sprayforming nozzle is mounted within the collector portion below the top portion of the support screen for directing a spray of water at substantially the entire downwardly facing surface of the chemical block supportably retained above the top portion of 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. The top portion of the support screen contacts the solid chemical only such that the container is allowed to fall unimpaired by force of gravity into the generally torroidal cavity as the chemical is used. Spray control means, 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. |
