Dual-Heating Deep Cooker for Uniform Inside-Out Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric deep cookers and fryers cook food from the outside in but fail to cook it evenly from the inside out, leading to undercooked or burnt results, and require lengthy cooking times, with the added risk of damaging electrical wires due to continuous rotation.
Innovation Solution
An electric deep cooker design featuring primary heating elements on the interior surface for outside-in cooking and an adjustable electric interior heating element for inside-out cooking, eliminating the need for food rotation by using a main body and cover that enclose food, with temperature control and power management systems for efficient cooking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If food is cooked from the outside in using conventional heating elements, then the exterior of the food is heated, but the interior remains undercooked and cooking time is extended
Solution Approach 1:
The patent places a heating element inside the food item, nesting the heating device within the food itself. This allows simultaneous heating from both the exterior (convection/radiation) and interior (direct contact), dramatically reducing cooking time while ensuring thorough cooking throughout the food item.
2Stability of the object's composition
If food is rotated continuously to achieve even cooking from all sides, then uniform exterior cooking is achieved, but electrical wires are twisted and damaged
Solution Approach 1:
Instead of rotating the food to achieve even cooking, the patent inverts the approach by inserting a heating element inside the food. This allows the food to remain stationary while still achieving uniform cooking through combined interior and exterior heating, eliminating wire twisting problems.
3Productivity
If an interior heating element is added to cook food from the inside out, then cooking time is reduced, but the device complexity increases
Solution Approach 1:
The heating element is designed to be inserted directly into the food item, which then serves as its own heating chamber. The food structure itself accommodates the heating element, eliminating the need for complex dedicated interior heating chambers or sophisticated control systems, thus limiting the increase in device complexity.
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 uniform and rapid cooking of food without rotation, reducing cooking time and preventing electrical wire damage, while ensuring even heating from both inside and outside.
Implementation Method 1
a plurality of primary electric heating elements connected along the interior surface of the main body and cover and adapted to uniformly heat and cook food through its entire outer surface from the outside in
Implementation Method 2
the plurality of primary heating elements heat and cook the food from the outside in
Implementation Method 3
an electric interior heating element attached to the cover and adapted to be placed within the food being cooked and thereby heat and cook the food from the inside out

AI summary
An electric deep cooker including a main body and cover adapted to fully enclose food therein that includes a plurality of main electric heating elements connected along the interior surfaces of the main body and cover and are adapted to uniformly heat and cook food through its entire outer surface from the outside in, and further includes an electric interior heating element attached to the cover and adapted to be placed within the food being cooked and thereby heat and cook the food from the inside out while the plurality of main heating elements heat and cook the food from the outside in, to thereby uniformly and properly heat and cook the food, and in a shorter amount of time, than prior art electric deep cookers, and without the need to rotate the food within the main body of the electric deep cooker.
