Portable hood
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixed hoods are inefficient in removing oil vapor generated during cooking due to a distance gap between the cooking location and the hood, leading to odor and stain issues, and are not portable for outdoor or non-traditional cooking setups.
Innovation Solution
A portable hood with a roll filter and adjustable sucking unit that can be positioned adjacent to cooking utensils, featuring a base unit, columnar unit, and head unit with a discharging unit to efficiently capture and remove oil vapor, and an air cleaning function, with components designed for easy maintenance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixing hood is installed above the heating appliance at a higher position for kitchen structure or cooking convenience, then the installation position is stable and accessible, but the distance between the cooking location and the sucking unit increases, reducing oil vapor removal efficiency
Solution Approach 1:
The patent applies the dynamics principle by making the hood portable rather than fixed, allowing it to be moved to different positions and heights. The hood can be positioned close to the cooking surface or adjusted to optimal heights, dynamically adapting to different cooking scenarios and utensil arrangements, thus maintaining both accessibility and high oil vapor removal efficiency.
2Stability of the object's composition
If a fixing hood is used in a fixed heating appliance location, then the hood structure is stable, but it cannot be used for portable burners, outdoor cooking, or non-traditional cooking setups
Solution Approach 1:
The patent applies the universality principle by designing a portable hood that can function with multiple types of heating appliances including fixed stoves, portable burners, and outdoor cooking equipment. The hood's portable design allows it to be used in diverse cooking locations and scenarios, making it universally applicable while maintaining structural stability during use.
3Reliability
If a traditional filter is used in the hood, then the filtration function is provided, but the filter requires complex maintenance and replacement procedures
Solution Approach 1:
The patent applies the segmentation principle by dividing the filtration system into modular components. The filter is designed as a separate, easily removable module that can be independently accessed and replaced without disassembling the entire hood structure. This segmentation simplifies maintenance procedures while ensuring reliable filtration function.
4Device complexity
If the sucking unit is positioned at a fixed height above the cooking surface, then the hood structure is simple, but it cannot adapt to different cooking utensil heights or positions
Solution Approach 1:
The patent applies the dynamics principle by enabling the sucking unit to be positioned at variable heights and angles. The hood can be adjusted to accommodate different cooking utensil heights and positions, dynamically adapting to various cooking scenarios while maintaining relatively simple structural design through adjustable mechanisms.
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 portable hood effectively captures oil vapor, prevents bypassing, and maintains cleanliness, while being stable and versatile for various cooking environments, enhancing cooking efficiency and hygiene.
Implementation Method 1
a purification filter, for example, an oil mist filter is installed to have a shape of a roll filter
Implementation Method 2
a discharging unit discharging the air introduced to the sucking unit to the outside

AI summary
A portable hood (10) is proposed. The portable hood (10) may include: a base unit (200), a head unit (100), a columnar unit (300), and a roll filter unit (600). The roll filter unit (600) may include a purification filter installed in the head unit (100) and discharged to the outside of the head unit (100) after moving past the sucking unit (110). Accordingly, one of purification filters, for example, an oil mist filter is provided as a roll filter, so the cleanliness maintenance and replacement of the filter is easy.
