Cooking Appliance Smoke Filtration Around the Upper Heating Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances, such as griddles, generate smoke and foul odors during cooking due to food contact with heating surfaces, which are not effectively contained or filtered, affecting convenience and cleanliness.
Innovation Solution
A smoke filter system is integrated into the cooking appliance, featuring a filter assembly within an air inlet surrounding the upper heating surface, utilizing an activated carbon cotton filter to remove particulates and impurities from the smoke, which is then exhausted as clean air through an exhaust vent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a filter is added to the air inlet to remove particulates from smoke, then the cleanliness of the cooking environment is improved, but the device complexity increases
Solution Approach 1:
The housing structure serves multiple functions: it contains the cooking chamber, provides structural support, and integrates the smoke filtration system. The air inlet is positioned to naturally capture smoke while the filter simultaneously performs particulate removal and odor reduction, making the system multi-functional without adding separate complex components.
Solution Approach 2:
A filter material with porous structure is installed in the air inlet to remove particulates from smoke. The porous structure allows the filter to trap particles while maintaining airflow, effectively reducing smoke and odors without requiring a complex filtration system.
2Object-affected harmful factors
If the filter is positioned in the air inlet surrounding the upper heating surface, then the smoke containment is improved, but the ease of manufacture decreases
Solution Approach 1:
The filter is integrated directly into the housing structure at the air inlet, merging the filtration function with the existing housing design. This eliminates the need for separate filter housing components and simplifies the manufacturing process while maintaining effective smoke containment around the upper heating surface.
3Ease of operation
If a smoke filter system is integrated into the cooking appliance, then the convenience of cooking is improved, but the device complexity increases
Solution Approach 1:
The smoke filter system operates automatically as part of the cooking process. Smoke generated during cooking is naturally drawn through the filter in the air inlet, providing self-service smoke reduction without requiring user intervention or complex control systems, thereby improving convenience without significantly increasing device complexity.
