Roll Filter Air Cleaner with Integrated Cutter for Kitchen Oil Mist
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Kitchen air cleaners are often ineffective due to improper maintenance, with oil mist and pollutants accumulating and reducing their efficiency, and existing air purifiers have issues with oil mist blocking air intake, spreading contamination, and being difficult to clean or maintain.
Innovation Solution
An air cleaner design featuring a removable pre-filter, a roll filter with a color-changing filter sheet and automatic unwinding mechanism, and a user-friendly interface for easy maintenance, including a filter cutter and magnetic coupling for secure attachment, ensuring efficient air filtration and reduced contamination spread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional air purifiers are used in kitchens, then they can filter air, but oil mist blocks air intake and reduces efficiency
Solution Approach 1:
The air cleaner is divided into multiple functional sections: a pre-filter section that captures oil mist before it enters the main filtration system, and a HEPA filter section that handles fine particles. This segmentation prevents oil mist from blocking the main air intake while maintaining high filtration efficiency.
Solution Approach 2:
A pre-filter acts as an intermediary component between the kitchen environment and the main HEPA filter. This pre-filter specifically targets and removes oil mist particles before they can reach and block the main filtration system, allowing the HEPA filter to focus on fine particle removal.
2Productivity
If air purifiers are placed in kitchens, then they can clean air, but discharged clean air mixes with dirty air and recirculates
Solution Approach 1:
The air cleaner utilizes vertical air flow by positioning the device on the countertop with air intake at the bottom and discharge at the top. This vertical dimension separates the clean air discharge path from the dirty air intake path, preventing recirculation and improving overall air cleaning effectiveness.
3Ease of operation
If filters are made removable for easy maintenance, then cleaning becomes simpler, but device complexity increases
Solution Approach 1:
The filtration system is segmented into a removable pre-filter and a fixed HEPA filter assembly. The pre-filter can be easily removed and washed by the user, while the HEPA filter remains sealed and integrated. This segmentation allows simple maintenance without requiring complex disassembly mechanisms.
Solution Approach 2:
The pre-filter is designed as a disposable or easily replaceable component that users can wash and reuse multiple times before replacement. This approach simplifies maintenance by eliminating the need for complex cleaning mechanisms while providing easy upkeep.
4Reliability
If air cleaners are designed with fixed filters for durability, then reliability improves, but maintenance becomes difficult
Solution Approach 1:
The filter system is divided into a durable, sealed HEPA filter assembly that maintains reliability and a separate, removable pre-filter that enables easy maintenance. The pre-filter protects the HEPA filter from oil mist accumulation, ensuring the main filter remains reliable while allowing simple user maintenance.

AI summary
An air cleaner includes a case, an air inlet, an air outlet, a grill covering the air inlet to filter airborne oil droplets, a fan to suction air through the air inlet and discharge air out of the air outlet, a roll filter provided between the grill and the fan to filter oil mist, and a filter roller to cut the roll filter. The roll filter includes a roller and a filter sheet wound around the roller, and the filter sheet may be unwound to extend behind the grill. When the filter sheet becomes dirty, the roll filter is further unwound so that a clean section is provided behind the grill, and the filter cutter may cut off the dirty section. During cutting, a clamp holds down the filter sheet. The case includes a slit through which the dirty section of the filter sheet passes for discarding.
