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. 11,857,108.

Summary of the Inventive Concept

This invention discloses an improved flange assembly for quick wok replacement and enhanced cooking performance in intelligent household appliances, addressing the limitations of the existing flange assembly design.

Background and Problem Solved

The original flange assembly patent (FIELD OF THE INVENTION) has inherent limitations, such as cumbersome wok replacement, heat loss during cooking, and lack of speed adjustment for optimized cooking performance. This new inventive concept solves these problems by introducing magnetic connection mechanisms, thermal insulation, shock-absorbing materials, and speed adjustment mechanisms.

Detailed Description of the Inventive Concept

The enhanced flange assembly features a magnetic connection mechanism between the first and second flanges, enabling quick and easy wok replacement. The wok assembly device incorporates a heating device thermally insulated from the wok to minimize heat loss during cooking. A shock-absorbing material replaces the resilient piece to reduce the impact of wok replacement on the cooking machine. Additionally, the driving device is equipped with a speed adjustment mechanism to optimize cooking performance based on the type of food being cooked.

Novelty and Inventive Step

The new claims introduce novel features not present in the original patent, including magnetic connection mechanisms, thermal insulation, shock-absorbing materials, and speed adjustment mechanisms. These features provide a non-obvious improvement over the existing flange assembly design, enhancing cooking performance, safety, and efficiency.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include different magnetic connection mechanisms, varying thermal insulation materials, or alternative shock-absorbing materials. The speed adjustment mechanism could be implemented using different sensors or algorithms to optimize cooking performance.

Potential Commercial Applications and Market

The enhanced flange assembly has significant commercial potential in the intelligent household appliances industry, particularly in the cooking machine segment. Target markets include high-end cooking appliance manufacturers and consumers seeking improved cooking performance and convenience.
