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. 11,857,132.

Summary of the Inventive Concept

The present disclosure relates to an improved cleaning device for kitchen tools, featuring adjustable inlet aperture, automatic cleaning parameter adjustment, UV sanitizing, self-cleaning body, and drying module, enhancing efficiency, safety, and hygiene in commercial and domestic kitchens.

Background and Problem Solved

The original cleaning device patent (referenced above) addressed the need for efficient cleaning of kitchen tools. However, it had limitations in accommodating varying tool sizes, lacking automated cleaning parameter adjustment, and not providing sanitizing or drying capabilities. The new inventive concept resolves these limitations, offering a more comprehensive and efficient cleaning solution.

Detailed Description of the Inventive Concept

The enhanced cleaning device comprises an adjustable inlet aperture, allowing for seamless accommodation of kitchen tools of varying sizes. The device is equipped with a detection system that identifies the type of inserted kitchen tool and automatically adjusts cleaning parameters accordingly. Additionally, the device features a UV light source for sanitizing the tool, a self-cleaning body that reduces bacterial growth, and a drying module that utilizes warm air to dry the tool after cleaning. These advancements ensure a more efficient, safer, and hygienic cleaning process.

Novelty and Inventive Step

The new claims introduce a novel combination of features, including adjustable inlet aperture, automatic cleaning parameter adjustment, UV sanitizing, self-cleaning body, and drying module, which collectively provide a significant improvement over the original patent. The inventive step lies in the integration of these features to create a more comprehensive and efficient cleaning device.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include variations in the detection system, such as using AI-powered tool recognition or incorporating sensors to detect tool material and adjust cleaning parameters accordingly. Other variations may include different UV light sources, self-cleaning materials, or drying module designs to further enhance the cleaning device's performance.

Potential Commercial Applications and Market

The enhanced cleaning device has significant commercial potential in the kitchen appliance industry, particularly in the commercial and domestic kitchen segments. The device's improved efficiency, safety, and hygiene features make it an attractive solution for restaurants, cafes, and households seeking to maintain high cleaning standards while reducing labor costs and environmental impact.
