Solution Overview

Problem

Existing cooking devices face challenges in cleaning due to oil fumes adhering to heating elements, which affects their operation and requires complex cleaning processes.

Innovation Solution

A cooking device design that includes a pot body with a cooking cavity and an installation cavity, where a heating element is located in the installation cavity and separated by a panel. This panel prevents oil smoke from adhering to the heating element, simplifying the cleaning process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the heating element is placed in the cooking cavity, then the heating element can directly heat the food, but oil fumes will adhere to the heating element making it difficult to clean

Engineering Contradiction:
Improveheating efficiencyVSAvoidcleaning ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent divides the cooking device into separate cavities: a cooking cavity for food and an installation cavity for the heating element. This segmentation prevents direct contact between oil fumes and the heating element, eliminating the cleaning problem while maintaining heating functionality through the panel structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heating element is extracted from the cooking cavity and placed in a separate installation cavity. This extraction removes the heating element from the harmful environment of oil fumes, preventing adhesion and simplifying maintenance while preserving its heating function through the panel.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the heating element is separated from the cooking cavity, then cleaning is simplified, but the heating element cannot directly heat the food

Engineering Contradiction:
Improvecleaning easeVSAvoidheating efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The panel acts as an intermediary between the installation cavity containing the heating element and the cooking cavity containing the food. It transmits thermal energy from the heating element to the food while maintaining physical separation, thus preserving heating efficiency while enabling easy cleaning.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces direct mechanical contact heating with thermal radiation or conduction through the panel. This substitution allows the heating element to heat food without physical contact, maintaining heating efficiency while eliminating oil adhesion issues.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If a panel is added to separate the cooking cavity and installation cavity, then oil smoke adhesion is prevented, but the device structure becomes more complex

Engineering Contradiction:
Improvecleaning easeVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The panel serves multiple functions: it acts as a structural support, a thermal transmission medium, and a separation barrier between the cooking and installation cavities. By combining multiple functions in a single component, the design achieves cavity separation without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the separation function with the structural and thermal functions in the panel. Instead of adding a separate complex separation mechanism, the panel itself is designed to perform all necessary functions, simplifying the overall structure while achieving the desired separation.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Disclosed is a cooking device including a pot body, a heating element and a panel. The pot body is provided with a cooking cavity and an installation cavity. The heating element is located in the installation cavity. The panel is assembled on the pot body and separates the cooking cavity and the installation cavity. In this way, the panel separates the cooking cavity and the installation cavity so that the panel can separate the cooking cavity and the heating element, which helps to prevent the oil smoke in the cooking cavity from adhering to the heating element and prevent the attached oil smoke from affecting the normal operation of the heating element. In addition, the panel separating the cooking cavity and the installation cavity also helps to reduce the structure of the cooking device that needs to be cleaned and facilitate the cleaning of the cooking device.
