Cooking Chamber Door Lock With Multi-Position Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking apparatuses lack enhanced safety and convenience features, particularly in the locking mechanism of the door, which can lead to accidental openings or unintended operation during cooking processes.
Innovation Solution
A cooking apparatus with a door lock system that includes an interference member and a lever mechanism, allowing for controlled opening and closing, featuring multiple positions for interference, release, and function release, ensuring safe operation and user convenience through double-locking and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple door locking mechanism is used, then the device complexity is reduced, but the safety and reliability of preventing accidental opening is compromised
Solution Approach 1:
The door lock system is segmented into multiple functional components: an interference member that physically blocks door opening, a lock case that houses and moves the interference member, and a lever that controls the interference member's position. This segmentation allows each component to perform its specific function efficiently while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The interference member is positioned in advance to block the door opening path before the door can be accidentally opened. The lock case is designed to automatically move the interference member into the blocking position, performing the safety action preliminarily and automatically, thus preventing accidental opening without requiring complex active control systems.
2Reliability
If a secure locking mechanism is implemented, then the reliability of safe operation is improved, but the ease of operation for intentional opening is reduced
Solution Approach 1:
The interference member is designed to be dynamically movable between a blocking position (for safety during cooking) and a retracted position (for intentional opening). The lever mechanism provides dynamic control, allowing the user to easily move the interference member when needed. This dynamic design ensures the door remains securely locked during cooking but can be easily opened when the user intends to access the cooking chamber.
3Ease of operation
If the interference member is freely movable, then the ease of operation is improved, but the reliability of maintaining locked state is worsened
Solution Approach 1:
The lock case is designed with specific local structural features that provide controlled guidance and support for the interference member. These local structural qualities ensure the interference member moves smoothly and easily in the intended direction while maintaining a stable, reliable locked state when positioned, without requiring the entire system to be complex.

AI summary
The cooking apparatus includes a main body forming a cooking chamber, a door configured to open and close the cooking chamber, and a door lock including an interference member configured to interfere with a movement of the door while opening the cooking chamber, and a lock case configured to accommodate the interference member so as to be movable therein. The interference member is configured to move to an interference position for applying an interference with opening the door, an interference release position for releasing the interference of opening the door, and a function release position for restricting the interference of opening the door, the function release position is a position in which the interference member is supported by the lock case and in which movement of the interference member is restricted to the interference release position and the interference position.
