Abstract

An apparatus for dispensing solid or semi-solid detergents includes a hollow elongated opening or chute and an arcuate plate that extends from the side wall of the apparatus to beneath the chute. This plate provides a planar support for a detergent bar placed within the chute. Water is sprayed down the arcuate plate and projects against the detergent supported on the planar support causing it to dissolve and flow down a drain. The chute has a unique geometric design which is suitable to receive only one uniquely shaped elongated detergent bar. In a kitchen having several detergent dispensers, each detergent dispenser will have a uniquely defined chute so that only the appropriate detergent can be used in the appropriate dispenser.

Claims

1. In combination an elongate solid detergent bar and an apparatus for dissolving said elongated solid detergent bar and dispensing dissolved detergent said combination comprising:

an outer wall, an elongated chute spaced from said outer wall and having an open top and an open bottom and having a cross-sectional configuration;

a planar support beneath said elongated chute spaced from said open bottom providing a gap of a predetermined height between said elongated chute and said planar support;

a solid detergent bar having a cross-sectional configuration substantially the same as the cross-sectional configuration of said elongated chute, said solid detergent bar resting in said elongated chute supported by said planar support whereby only a lower cross-sectional portion of said solid detergent bar is exposed at said gap, said lower cross-sectional portion having a thickness equal to said predetermined height;

means to project water at said gap and drain beyond said gap;

whereby said exposed portion of said solid detergent bar at said gap is dissolved by water projected at said gap and as said exposed portion is dissolved and removed by water flowing toward said drain, fresh solid detergent bar advances into said gap to provide a new lower cross-sectional portion of said solid detergent bar.

2. The combination claimed in claim 1 wherein said elongated chute supports a sensor capable of detecting the presence of said solid lower cross-sectional portion of said solid detergent bar in said elongated chute.
