First Claim
1. A method for dispensing a use solution from a solid detergent into a washing machine, comprising the steps of:
- a. placing a solid detergent having a bottom in a dispenser, the dispenser having a chamber, the chamber defining a cavity and including a water inlet and a water outlet, and the cavity being configured and arranged to receive the solid detergent;
b. supplying water to the water inlet of the dispenser, wherein the water is supplied to a level within the cavity of the chamber thereby having contact with the solid detergent;
c. flooding the cavity with water from the bottom of the solid detergent;
d. dissolving a relatively small portion of the solid detergent in the water and forming a use solution, the solid detergent being dispensed completely over more than one flooding of water within the cavity; and

Abstract
A solid detergent dispenser for use with a dishwashing machine includes a chamber and a lid. The chamber is configured and arranged to receive a solid detergent having a particular composition. A water inlet receives water from a water source, and the water flows through a tunnel into the bottom of the chamber. The chamber is flooded with water from the bottom to ensure relatively constant erosion of the solid detergent, which ensures that a relatively constant concentration of the solid detergent is used in the dishwashing machine. A water outlet allows water to flow out of the chamber into the dishwashing machine. The water must flow into the chamber faster than it flows out of the chamber to ensure that the appropriate amount of dissolution of the solid detergent occurs. The only valve used in the preferred embodiment is a valve to control the amount of water flowing into the water inlet.
