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

An improved flange assembly for quick replacement of a wok, featuring enhanced safety, efficiency, and cleanliness, designed for intelligent household appliances.

Background and Problem Solved

The original patent for the flange assembly for quick replacement of a wok and wok assembly device has limitations in terms of safety, temperature control, and cleaning. The new inventive concept addresses these limitations by introducing a temperature sensing unit, speed adjustment mechanism, safety locking mechanism, and detachable protective shell.

Detailed Description of the Inventive Concept

The enhanced flange assembly comprises a first flange, a second flange, and at least one resilient piece. The first flange is fixedly connected to a bottom portion of the wok and detachably connected to the second flange in a clamped manner. The second flange is rotatably connected to a driving device. Additionally, the flange assembly includes a temperature sensing unit to monitor the temperature of the wok during cooking, a speed adjustment mechanism to adjust the rotational speed of the wok according to different cooking requirements, and a safety locking mechanism to prevent accidental detachment during cooking. The wok assembly device further comprises a heating device and a protective shell designed to be detachable and washable, improving overall cleanliness and hygiene.

Novelty and Inventive Step

The new inventive concept's novelty lies in the integration of a temperature sensing unit, speed adjustment mechanism, safety locking mechanism, and detachable protective shell, which provide enhanced safety, efficiency, and cleanliness compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the design of the temperature sensing unit, speed adjustment mechanism, and safety locking mechanism. Additionally, the flange assembly could be adapted for use with different types of cooking vessels or appliances.

Potential Commercial Applications and Market

The enhanced flange assembly has significant commercial potential in the intelligent household appliances industry, particularly in the market for high-end cooking machines and smart kitchen devices.
