Movable Heating Element for Cooking Appliance Cleaning Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking appliances face challenges in accessing surfaces adjacent to the heating element for cleaning due to its positioning, which either obstructs access or reduces heat transfer.
Innovation Solution
A cooking appliance with a heating element that is movably mounted within the heated chamber, allowing it to be positioned between a first position adjacent to one wall and a second position spaced apart from the wall, facilitating cleaning while maintaining effective heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heating element is positioned within the heated chamber for direct heating, then heat transfer efficiency is improved, but access to adjacent surfaces for cleaning is obstructed
Solution Approach 1:
The heating element is made movable between a retracted position (within the heated chamber for direct heating) and an extended position (outside the heated chamber for cleaning access). This dynamic positioning allows the system to switch between optimal heating configuration and optimal cleaning configuration, resolving the contradiction between heat transfer efficiency and ease of surface access.
2Ease of operation
If the heating element is positioned outside the heated chamber separated by a vented partition, then access to surfaces for cleaning is improved, but heat transfer to the heated chamber is reduced
Solution Approach 1:
The heating element can be dynamically positioned inside or outside the heated chamber. When positioned outside, cleaning access is improved; when positioned inside, heat transfer efficiency is maximized. This dynamic capability allows the system to optimize for either cleaning or heating depending on operational needs.
3Device complexity
If the heating element is fixed in position, then device complexity is reduced, but versatility in accommodating different operational needs is limited
Solution Approach 1:
The heating element is mounted on a movable mechanism that allows it to be repositioned between inside and outside the heated chamber. This dynamic mounting provides versatility to accommodate both direct heating operations and cleaning operations, while the mechanical design maintains reasonable complexity through the use of a telescoping or sliding mechanism.

AI summary
A cooking appliance includes a cabinet and a heated chamber positioned within the cabinet. The heated chamber is defined by a plurality of walls. The cooking appliance also includes a heating element positioned within the heated chamber. The heating element is movably mounted within the heated chamber such that the heating element is movable between a first position and a second position. The first position may be adjacent one wall of the plurality of walls and the second position may be spaced apart from the one wall of the plurality of walls. The first position may be approximately parallel to a horizontal direction and the second position may be approximately perpendicular to the horizontal direction.
