Solution Overview
Problem
Existing cooking utensils with air frying and pressure cooker functions require two lids and two separate heating systems, leading to high costs and inefficiencies due to the need for dual electricity usage.
Innovation Solution
A cooking utensil design that utilizes a single lid and heating plate, incorporating a fan subassembly with a centrifugal air turbine and cooling fan to convert a pressure cooker into an air fryer by circulating heated air through a vertical column and air frying subassembly, allowing for both functions with a single lid and reduced energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two lids are equipped (one for pressure cooker, one for air fryer), then both air frying and pressure cooker functions can be achieved, but the cost increases significantly
Solution Approach 1:
The single lid is designed to perform both pressure cooking and air frying functions by integrating a heating device and air supply device within the same lid structure, eliminating the need for separate lids for each cooking mode
Solution Approach 2:
The heating device and air supply device are merged into a single integrated lid assembly, allowing one lid to fulfill multiple cooking functions that previously required separate dedicated lids
2Adaptability or versatility
If two separate heating systems are used (one for pressure cooker, one for air fryer), then both cooking modes can operate independently, but energy consumption increases
Solution Approach 1:
A single heating device is designed to serve both pressure cooking and air frying modes, reducing energy consumption by eliminating redundant heating systems while maintaining the ability to operate in either mode independently
Solution Approach 2:
The heating system is merged into a unified design where the same heating device provides thermal energy for both cooking modes, reducing overall energy requirements compared to having separate heating systems
3Adaptability or versatility
If an electric coupler is set up between air fryer lid and cooker body, then electrical connection is established for air frying function, but the device complexity and cost increase
Solution Approach 1:
The lid incorporates both heating and air supply devices with integrated electrical connections, allowing the same lid to perform air frying without requiring additional electric couplers or complex wiring arrangements
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
Enables efficient air frying and pressure cooking with a single lid, reducing costs and energy consumption while maintaining performance, by using a single heating system and fan assembly to circulate heated air for cooking.
Implementation Method 1
a heating plate (5) is arranged above a bottom surface of the middle housing (15)
Implementation Method 2
the fan subassembly blows heat generated by the heating plate to an inner cavity of the air frying subassembly
Implementation Method 3
the centrifugal air turbine draws the air in the cavity of the middle housing into the bottom surface of the middle housing and exchanges heat with the heating plate

AI summary
The present disclosure relates to a cooking utensil with air frying and pressure cooker functions. The cooking utensil includes a cooker body (1), an inner pot (2), a lid (4), and a heating plate (5); the cooker body (1) includes a middle housing (15) and an outer housing (23); the heating plate (5) is arranged above a bottom surface of the middle housing (15); the inner pot (2) is arranged in an inner cavity of the middle housing (15). When the air frying subassembly (3) is put into the cooker body, the fan subassembly works, and the centrifugal air turbine (12) draws air in the cavity of the middle housing (15) into the bottom surface of the middle housing (15) and exchanges heat with the heating plate (5) to cook food.
