Air Fryer Broiling Board Design for Multi-Function Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air fryers are limited to single air frying functions, restricting their usage range.
Innovation Solution
An air fryer design incorporating a broiling board at the bottom of the frying basket, equipped with flow guide convex ribs, which allows for broiling and baking functions while maintaining the original air frying capabilities, utilizing a heating plate and heat circulation fan to achieve higher temperatures for cooking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-pot frying basket structure is used, then the device is simple and easy to manufacture, but the usage range is limited to single air frying function
Solution Approach 1:
The patent applies multi-functionality by integrating a broiling board into the frying basket structure. The broiling board can be installed in the frying basket body to enable broiling and baking functions, while the original air frying function remains available. This allows one device to perform multiple cooking functions (air frying, broiling, baking) without requiring separate appliances, thereby increasing adaptability while maintaining reasonable structural complexity through modular design.
2Adaptability or versatility
If a broiling board is added to enable broiling and baking functions, then the usage range is enlarged, but the device structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the frying basket into modular components: the frying basket body, the broiling board, and the heating plate. The broiling board is designed as a separate, detachable component that can be installed or removed as needed. This modular segmentation allows the device to gain additional cooking functions while maintaining the simplicity of the original structure when the broiling board is not in use, and facilitates easy cleaning and maintenance of individual components.
3Object-generated harmful factors
If the broiling board covers the hollowed-out opening, then grease containment is improved, but airflow guidance may be affected
Solution Approach 1:
The patent applies local quality by designing the broiling board with specific structural features at different locations: the peripheral wall extends to cover the hollowed-out opening to contain grease, while the central portion includes convex ribs that create channels for hot air flow. This localized differentiation allows the broiling board to simultaneously achieve grease containment at the edges and maintain efficient airflow guidance at the center, resolving the contradiction between these two functions.
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
Enlarges the usage range of air fryers by enabling broiling and baking functions, ensuring better cooking effects through the exposure of food surfaces and efficient airflow guidance, while maintaining the original air frying functionality.
Implementation Method 1
the broiling board is heated by the heating plate
Implementation Method 2
hot air generated by the heating device is blown by the heat circulation fan to a lower part of the cooking cavity
Implementation Method 3
the flow guide convex ribs further may guide hot air when performing the broiling and baking functions and the air frying function, to converge airflow into the center portion of the broiling board
