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

An improved dishwashing system that reuses waste water from previous wash and rinse cycles, reducing total water consumption and associated energy costs, while also providing real-time monitoring and control for optimized cleaning efficiency.

Background and Problem Solved

The original patent described a dishwashing system that utilized recycled wash and rinse water for the pre-rinse operation. However, this system had limitations in terms of water quality monitoring, temperature and chemical composition control, and real-time optimization. The new inventive concept addresses these limitations by integrating a water recycling unit, a sensor to monitor water quality, and a control unit to optimize water usage and energy consumption.

Detailed Description of the Inventive Concept

The enhanced dishwashing system comprises a water recycling unit that filters and treats the waste water from previous wash and rinse cycles. The recycled water is then used for the pre-rinse operation, reducing the total water consumption and associated energy costs. The system also includes a sensor to monitor the water quality and adjust the recycling process accordingly. A control unit optimizes the water usage and reduces energy consumption by adjusting the temperature and chemical composition of the recycled water to match the requirements of the pre-rinse operation. Additionally, the system features a real-time monitoring and control system that tracks water usage, energy consumption, and cleaning efficiency, providing recommendations for optimizing the dishwashing process.

Novelty and Inventive Step

The new inventive concept introduces the integration of a water recycling unit, a sensor, and a control unit to optimize water usage and energy consumption, which is not present in the original patent. The real-time monitoring and control system is also a novel feature that provides a significant improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of sensors to monitor water quality, implementing various control algorithms to optimize water usage, or incorporating additional features such as automatic detergent dosing or advanced cleaning modes.

Potential Commercial Applications and Market

The enhanced dishwashing system has significant commercial potential in the hospitality, healthcare, and foodservice industries, where water and energy conservation are critical. The system's ability to reduce water consumption and energy costs, while also providing real-time monitoring and control, makes it an attractive solution for businesses looking to reduce their environmental footprint and operating expenses.
