Removable Bottom Panel Assembly for Tool-Free Oven Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current oven appliances require cumbersome and inefficient methods for cleaning the bottom panel, which can be dangerous and ineffective, as users must reach into the cooking chamber to scrub the panel, and high-temperature pyrolytic cleaning operations are not always effective.
Innovation Solution
A removable bottom panel assembly for oven appliances that includes a panel with a front air deflector and a retention clip, allowing for easy removal and installation without tools, and coated with a non-stick enamel for enhanced cleanability, facilitating easier maintenance and improved air circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bottom panel is made removable for easy cleaning, then the ease of operation is improved, but the device complexity increases due to additional retention mechanisms
Solution Approach 1:
The bottom panel assembly is segmented into a removable panel portion and a fixed retention clip portion. The panel can be separately removed from the cooking chamber by disengaging from the retention clip, allowing easy cleaning without removing the entire assembly. This segmentation enables independent cleaning of the contaminated panel while leaving the retention mechanism in place.
Solution Approach 2:
The panel is designed to be extractable from the cooking chamber through a simplified removal process. The panel portion can be taken out by releasing it from the retention clip, which remains fixed in the cooking chamber. This extraction capability allows users to remove only the dirty panel for cleaning without dealing with complex disassembly procedures.
2Device complexity
If conventional cleaning methods are used (reaching into cooking chamber to scrub), then the device complexity is minimized, but the safety deteriorates due to exposure to high temperature and contaminants
Solution Approach 1:
The panel is designed to be extractable from the cooking chamber before cleaning operations. Users can remove the panel by releasing it from the retention clip and cleaning it outside the high-temperature cooking chamber environment. This extraction eliminates the need for users to reach into the hot chamber to scrub the panel, removing exposure to thermal and contamination hazards.
Solution Approach 2:
The panel can be removed and cleaned before the cooking chamber reaches high operating temperatures, or between cooking cycles. The retention clip design allows for quick panel removal, enabling preliminary cleaning actions to be taken before hazardous conditions develop in the cooking chamber, preventing user exposure to harmful environments.
3Ease of operation
If pyrolytic cleaning operation is used to burn off contaminants, then the manual cleaning effort is reduced, but the energy consumption increases and the effectiveness is limited
Solution Approach 1:
The panel can be extracted from the cooking chamber and cleaned separately using conventional low-energy methods such as washing with water and detergent. This eliminates the need to use high-energy pyrolytic cleaning operations for panel maintenance. Users can clean the removed panel using minimal energy consumption while maintaining effective contaminant removal.
Solution Approach 2:
The panel is designed as a consumable component that can be easily replaced or frequently cleaned at low cost. Rather than investing energy-intensive pyrolytic cleaning cycles, the system allows for economical panel maintenance through simple removal and washing. The panel serves as a replaceable element that maintains overall system effectiveness without requiring high-energy regeneration processes.

AI summary
An oven appliance includes a plurality of sidewalls defining a cooking chamber, a door to selectively open and close the cooking chamber; and a bottom panel assembly removably provided within the cooking chamber. The bottom panel assembly includes a panel defining an aperture, a front air deflector attached to the panel at the aperture, and a retention clip provided within the cooking chamber, the retention clip defining a receiving slot to selectively receive the panel when the panel is in an installed position.
