Extractor Hood Filter Access Through Removable Partition Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extractor hoods with complex constructions and time-consuming processes for filter replacement, requiring numerous steps and additional external openings, complicate the handling and maintenance of filter elements.
Innovation Solution
The extractor hood design features a removable separating element with a partition that closes the access opening between the negative and positive pressure sections, allowing for easy access and removal of the filter element through the air intake opening, eliminating the need for additional external openings and simplifying the filter change process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter element is arranged in the overpressure section behind the fan, then the filter can effectively reduce odors in the air flow, but the filter element becomes difficult to access for replacement requiring additional external openings and numerous manual steps
Solution Approach 1:
The extractor housing is divided into a negative pressure section and a positive pressure section separated by a removable partition. The partition can be detached to provide access to the filter element in the overpressure section through the air intake opening, enabling easy filter replacement without additional external openings while maintaining effective odor reduction
Solution Approach 2:
The air intake opening serves dual purposes: it functions as the primary air intake during operation and as an access point for filter element replacement when the partition is removed. This eliminates the need for separate access openings and simplifies the overall structure
2Reliability
If the extractor hood has a complex construction with separate access openings and multiple manual steps for filter replacement, then the filter can be effectively positioned, but the handling and maintenance become time-consuming and complicated
Solution Approach 1:
The removable partition divides the housing into accessible sections and can be quickly detached to expose the filter element. This segmented design allows rapid access to the filter through the existing air intake opening, significantly reducing filter replacement time while maintaining proper filter positioning
Solution Approach 2:
The partition is pre-arranged to block the access path to the filter during normal operation. When filter replacement is needed, the partition is simply removed to open the access path. This preliminary arrangement ensures the filter remains securely positioned during operation while enabling quick access when needed
