Induction Range Ventilation With Movable Exhaust And Grease Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional induction range hoods struggle with efficiently exhausting vapor-containing indoor air and removing condensed grease, often obstructing fire extinguisher placement and failing to provide adequate lighting and easy filter replacement, leading to contamination and reduced usability.
Innovation Solution
An induction ventilation system with a vertically movable unit for air exhaust, a grease tray for collecting condensed grease, a built-in lamp, and an anti-contamination member that prevents foreign matter from entering storage portions, allowing for easy filter replacement and uniform fire extinguisher spray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional induction range hood is hung above the induction range to collect and discharge condensed water or oil, then vapor exhaust function is provided, but the space above the induction range hood cannot be used as a storage portion and the filter screen obstructs fire extinguisher nozzle placement
Solution Approach 1:
The invention divides the range hood system into separate functional modules: the air suction unit with filter screen is separated from the storage portions (first storage portion above the upper plate and second storage portion below). This segmentation allows the storage portions to be independently accessible and usable without interference from the exhaust components.
Solution Approach 2:
The invention relocates the air suction opening to the rear surface of the upper plate rather than using a top-mounted hood structure. This dimensional change enables the first storage portion to be positioned above the upper plate without being obstructed by exhaust components, while the second storage portion is positioned below, effectively utilizing vertical space in multiple dimensions.
2Ease of operation
If an induction range hood is equipped with an exhaust fan and exhaust duct, then gas discharge function is provided, but the space above the induction range hood cannot be used as a storage portion
Solution Approach 1:
The invention segments the exhaust system into a separate air suction unit that is integrated into the rear surface of the upper plate, while the storage portions (first and second storage portions) are positioned above and below the upper plate respectively. This segmentation allows both exhaust and storage functions to coexist without spatial conflict.
Solution Approach 2:
The air suction opening is positioned on the rear surface of the upper plate rather than using a top-mounted hood, enabling the first storage portion to occupy the space above the upper plate. The exhaust duct extends rearward from this opening, utilizing horizontal space rather than vertical space, thereby preserving the volume available for storage portions.
3Productivity
If a vertically movable unit is installed in a rear portion of a first storage portion to exhaust indoor air, then vapor exhaust efficiency is improved, but the device complexity increases
Solution Approach 1:
The invention incorporates a vertically movable unit (air suction unit) that can move between an upper position (when no cooking vessel is present) and a lower position (when a cooking vessel is placed on the induction range). This dynamic positioning allows the system to adapt to different cooking conditions, improving vapor exhaust efficiency when needed while maintaining a compact profile when not in use.
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
Facilitates efficient vapor exhaust, easy grease removal, reduces contamination, enables effective fire extinguisher use, and provides adequate lighting without additional lamps, maintaining a clean and functional kitchen environment.
Implementation Method 1
an air suction fan that is installed in the chamber and sucks in indoor air through an air suction passage
Implementation Method 2
collects grease from the indoor air that is drawn by the air suction fan
Implementation Method 3
collects grease condensed on the wall of an air suction passage, a filter, a flexible duct, and a chamber and that falls down due to its weight
Implementation Method 4
an induction range is a heater that uses electromagnetic induction for heating... an induction current that is generated by magnetic field as a heat source
Implementation Method 5
eddy currents occurs on the surface of the metallic bottom due to electromagnetic induction, and the vessel is heated by the eddy currents
Implementation Method 6
an air supply fan that is installed in the air supply hood and draws outdoor air through an air supply passage
