Barbecue Extractable Cooking Surface for Hood-Closed Food Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Barbecue appliances with hoods experience temperature fluctuations due to frequent hood openings, reducing the efficiency of catalytic conversion processes and posing safety risks during food management.
Innovation Solution
A barbecue design featuring a hood with a fixed and movable part, where the cooking surface is extractable without opening the hood, maintaining a stable temperature within the cooking cavity and improving catalytic filter efficiency, while allowing safe and convenient food inspection and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hood is opened frequently to inspect and manage food items, then the user can monitor and handle the cooking process, but the temperature within the cooking cavity fluctuates significantly, reducing catalytic conversion efficiency
Solution Approach 1:
The cooking surface is segmented from the hood structure, allowing it to be independently extracted and retracted. This segmentation enables food inspection and management without requiring the entire hood to be opened, thus maintaining temperature stability while providing operational access.
Solution Approach 2:
The cooking surface is extracted as a separate movable component that can be removed from the lower housing for food inspection and management. This extraction allows users to access food items without opening the hood, preventing temperature fluctuations and maintaining catalytic conversion efficiency.
2Ease of operation
If the hood is opened to handle food items, then the user can access and manipulate the food, but the risk of accidental hood downfall onto user hands increases
Solution Approach 1:
The cooking surface is separated from the heavy hood structure, allowing food handling operations to be performed on the lightweight, movable cooking surface. This eliminates the safety hazard of heavy hood downfall while maintaining full functionality for food inspection and manipulation.
Solution Approach 2:
The cooking surface is extracted as an independent movable element that can be safely handled for food management tasks. By performing all food handling operations on this lightweight extracted component rather than opening the heavy hood, user safety is significantly improved.
3Ease of operation
If the cooking surface is made extractable for convenient food management, then the user can inspect and handle food easily, but the device complexity increases
Solution Approach 1:
The coupling mechanism between the cooking surface and lower housing is designed with localized sliding features and guide rails at specific positions. This localized quality approach provides the necessary extraction and retraction functionality while keeping the overall structure simple and avoiding excessive complexity throughout the entire device.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution stabilizes the cooking temperature, enhances catalytic conversion efficiency, and reduces the risk of hood accidents, enabling efficient and safe food handling and cooking.
Implementation Method 1
the barbecue appliance (1) comprises a catalytic filter assembly (40) positioned in the hood (20), configured to catalytically oxidize grease, fats, oils and/or other hydrocarbons in an air stream emanating from a cooking grill
Implementation Method 2
The Applicant further observes that the temperature required to support a catalytic reaction can be provided, at least in part, by the heat released from hot gases (combustion smoke and food cooking smoke/odours) passing through the catalytic filter from the grill cavity
