Solution Overview
Problem
In induction heating cooking appliances with multiple coils, operating multiple operation portions for multiple cooking containers is cumbersome, and the position-dependent operation interface complicates user experience, making it difficult to select appropriate cooking menus and position cooking containers optimally.
Innovation Solution
A cooking apparatus with a top plate, multiple heating coils, a heating controller, temperature detectors, and a cooking container detector that displays cooking container icons and menus based on size and shape, allowing for intuitive operation and safe cooking by separating display areas for placement state and menu selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation portions are provided for multiple heating coils, then each cooking container can be heated independently, but the operation portions become small and difficult to operate
Solution Approach 1:
The patent combines multiple operation portions into a single shared operation portion that displays and controls multiple cooking containers. Instead of providing separate operation portions for each heating coil, the system integrates them into one interface that can handle multiple containers simultaneously, making the operation portions larger and easier to operate while maintaining the ability to heat multiple containers independently
2Adaptability or versatility
If the operation position changes according to the cooking container position, then the interface adapts to container placement, but it becomes difficult for users to get used to the operation
Solution Approach 1:
The patent implements a universal operation portion that serves all cooking containers regardless of their placement position. The single operation portion displays information for multiple containers and allows control of any container from the same location, making the interface consistent and familiar to users while still adapting to show the appropriate container information based on what is placed on the hot plate
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 simplifies operation by displaying relevant menus based on cooking container position and size, ensuring easy and safe use, even when multiple containers are present, by maintaining a consistent operation interface and enhancing usability and safety.
Implementation Method 1
a plurality of heating coils configured to generate an induction magnetic field for heating the cooking container
Implementation Method 2
at least one or more temperature detector means configured to be disposed at the center or in the vicinity of the heating coils and detect the temperature of the cooking container
Implementation Method 3
a cooking container detector portion configured to supply the heating coils with a high-frequency current in predetermined time intervals and determine the placement state and the material of the cooking container

AI summary
When a cooking container 1 is placed on a top plate 2, a cooking container detector portion 5, which determines whether the cooking container 1 is placed and further determines a size of the cooking container 1, determines a placement and the size or a shape of the cooking container 1 to display a cooking container icon in a placement state display area 11, display a cooking menu icon corresponding to the cooking container icon in a menu selection area 9 of an operation portion 6. The cooking menu is set by selecting an icon display. As a result, it is possible to prevent complicating an operating method, and to realize an easy-to-understand operation.
