Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air heating type cooking pans have limitations in uniform heating, are inconvenient to clean, and cannot handle large food pieces due to fixed hot air direction and internal stirring paddles that are ineffective during frying or baking.
Innovation Solution
An air heating cooking pan design featuring a rotating pan body with support roller wheels, a non-round rotary head, and a hot air generating system with a centrifuge wind wheel and PTC heating element, eliminating the need for an internal stirring paddle by ensuring uniform heating and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a stirring paddle is installed in the pan body to stir food during heating, then uniform heating is achieved, but the cooking scope is limited to small pieces of food and it is inconvenient to clean the pan body
Solution Approach 1:
The stirring paddle is completely removed from the pan body. Instead of stirring mechanically, the pan body itself rotates to achieve uniform heating, allowing large pieces of food to be cooked without obstruction and making the pan body easy to clean.
Solution Approach 2:
The pan body is designed to rotate dynamically during heating instead of remaining stationary. This rotation enables uniform heat distribution across the food while accommodating various food sizes and eliminating the need for internal stirring mechanisms.
2Temperature
If a stirring paddle is installed in the pan body to stir food during heating, then uniform heating is achieved, but the structure becomes complex and difficult to clean
Solution Approach 1:
The stirring paddle and its drive mechanism are completely removed. The heating uniformity is achieved by rotating the pan body itself, which eliminates complex internal structures and makes the pan body simple and easy to clean.
Solution Approach 2:
The pan body serves dual functions: it contains the food and simultaneously acts as the rotating element for heat distribution. This eliminates the need for separate stirring mechanisms and simplifies the overall structure.
3Device complexity
If the hot air generating device blows hot air in a fixed direction, then the heating process is simple, but the interior of the pan body cannot be heated uniformly
Solution Approach 1:
The pan body rotates during heating, dynamically changing the position of food relative to the fixed hot air source. This rotation ensures all surfaces of the food are exposed to hot air uniformly, achieving even heating without complex multi-directional heating systems.

Implementation Method 1
a heating element and a thermal insulating fairing; the fixed mount is connected with the thermal insulating tray; one end of the blowing motor is connected with the outer side of the fixed mount, while the other end faces an air suction opening on the bottom shell; the centrifuge wind wheel is disposed on the inner side of the fixed mount and is in connection with the blowing motor in a transmission way; the heating element is disposed at the upper end of the fixed mount and close to the hot air outlet
Implementation Method 2
the hot air generating device consists of a centrifuge wind wheel, a blowing motor, a fixed mount, a heating element and a thermal insulating fairing; the centrifuge wind wheel is disposed on the inner side of the fixed mount and is in connection with the blowing motor in a transmission way
Implementation Method 3
the thermal insulating fairing is fixed at the upper end of the fixed mount and located on the outer side of the heating element; the thermal insulating fairing contains the heating element inside and together with fixed mount forms a hot air channel
Implementation Method 4
the turntable motor is disposed in the machine body; a motor shaft of the turntable motor drives the pan body to rotate via a driving member; the support roller wheels are circumferentially distributed and located between the bottom of the pan body and the bottom of the heating chamber

AI summary
Disclosed is an air heating type cooking pan which comprises a machine body, a cover body and a pan body; the machine body is provided with a heating chamber and a hot air generating device which blows hot air into the heating chamber; one side of the heating chamber is opened; the pan body is placed in the heating chamber from the opened side of the heating chamber; the cover body covers the outer side the opening of the heating chamber; characterized in that, a turntable motor and at least three support roller wheels are also comprised; the turntable motor is disposed in the machine body; a motor shaft of the turntable motor drives the pan body to rotate via a driving member; the support roller wheels are circumferentially distributed and located between the bottom of the pan body and the bottom of the heating chamber. When the air heating type cooking pan is in the heating process, the pan body is rotary relative to the hot air outlet, so each part of the pan body has the opportunity to be directly blown by the hot air from the hot air outlet, thus achieving the purpose of uniform heating; between the bottom of the pan body and the heating chamber are disposed support roller wheels, so the pan body more smoothly rotates.
