This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,133.

Summary of the Inventive Concept

A next-generation dishwashing system that integrates artificial intelligence, water recycling, and advanced filtration to minimize water waste, reduce energy consumption, and optimize cleaning efficiency.

Background and Problem Solved

The original patent, 'Use of recycled wash and rinse water for the pre-rinse operation of dishes,' demonstrated a basic approach to water recycling in dishwashing machines. However, it had limitations in terms of water quality, filtration, and optimization. The new inventive concept addresses these limitations by incorporating AI-driven optimization, advanced filtration, and real-time monitoring to create a more efficient, sustainable, and intelligent dishwashing system.

Detailed Description of the Inventive Concept

The intelligent water recycling system consists of a waste water recycling module, a pre-rinse module, and a central processing unit. The waste water recycling module filters and disinfects the waste water, while the pre-rinse module uses the recycled waste water to rinse soiled dishes. The central processing unit, integrated with artificial intelligence, optimizes water usage based on soil level, dish type, and real-time monitoring data. The system also includes sensors to monitor water usage, temperature, and chemical composition, enabling real-time adjustments to minimize water waste and optimize cleaning efficiency.

Novelty and Inventive Step

The new inventive concept's integration of artificial intelligence, advanced filtration, and real-time monitoring distinguishes it from the original patent. The AI-driven optimization and real-time monitoring enable the system to adapt to various dish types, soil levels, and operating conditions, making it a significant improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include modular designs, different types of filtration systems, or integration with other smart appliances. Variations could also include adapting the system for use in different industries, such as healthcare or hospitality.

Potential Commercial Applications and Market

The intelligent water recycling system has significant commercial potential in the dishwashing industry, particularly in commercial and industrial settings where water conservation and efficiency are critical. Target markets could include restaurants, hotels, hospitals, and other institutions seeking to reduce their environmental footprint and operating costs.
