AI Technical Summary

Technical Problem

In dishwashers using liquid or gel detergents, the dispenser design allows for uncontrolled leakage of detergent due to gravitational forces when the door transitions from an open to a closed position, leading to insufficient detergent use and door staining.

Method used

A dishwasher design featuring a storage receptacle with a reservoir, a first opening on the reservoir base, a second opening on the side wall, and an inclined surface that directs detergent back into the receptacle, preventing uncontrolled discharge by using a barrier to guide the detergent flow.

Benefits of technology

Prevents detergent leakage and ensures efficient use by maintaining the detergent within the dispenser, thereby avoiding door staining and ensuring optimal cleaning performance.
