Abstract
A dishwashing apparatus designed in such a manner as to have one incoming waterline and self cleaning filters. Solid additive sources are situated in containers mounted on top of the dishwashing apparatus and fed with water by means of a pump. A flip-top solid detergent dispenser comprising a base having a funnel-shaped interior, a nozzle positioned within the interior of the base, and a detergent container support connected by a hinge to the base can be mounted on the dishwashing apparatus. The detergent container support is designed to hold only a particular shaped detergent container and to prevent dripping of detergent solution upon the user. A circular metallic ring having a plurality of holes is situated around the funnel-shaped interior of the base. Water is flushed through the holes of the circular metallic ring at designated times to purge one of the filters of air and to insure that the detergent is rinsed down through the funnel-shaped interior of the base.
