Air Cleaner Top Cover for Radial Air Diffusion and Space Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners face challenges in utilizing the space above the device effectively, as the design often restricts the use of this area due to the placement of components such as fans and filters, limiting the ability to diffuse filtered air widely and efficiently within indoor spaces.
Innovation Solution
The air cleaner design incorporates a second body positioned above the first body, which guides air discharged from the outlet in a radially outward direction, allowing for the utilization of space above the cleaner and functioning as a table, while incorporating features like magnetic members and grooves to prevent foreign substances from entering the air cleaner's internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fan is disposed above an air cleaner to form an upward air flow, then the air flow direction can be changed, but the space above the air cleaner cannot be utilized
Solution Approach 1:
The upper cover is designed to serve dual purposes: it covers the internal components of the air cleaner while simultaneously providing a functional surface that can be utilized as a table or workspace. This multi-functional design resolves the contradiction by making the space above the air cleaner useful without adding complex external structures.
Solution Approach 2:
The patent merges the protective cover function with the table surface function into a single integrated component (the upper cover). By combining these two functions into one structure, the design achieves space utilization without increasing device complexity through separate additional components.
2Productivity
If the outlet is opened in up-down direction to discharge filtered air, then air clearness can be increased, but the space above the air cleaner becomes difficult to utilize
Solution Approach 1:
The outlet is positioned at a specific location on the upper cover (not blocking the entire upper surface), allowing filtered air to be discharged effectively while preserving the usability of the surrounding space above the air cleaner. This localized outlet design maintains both air diffusion efficiency and space usability.
Solution Approach 2:
The air discharge function is integrated into the horizontal surface of the upper cover, transforming the vertical air flow concept into a horizontal discharge arrangement. This dimensional adjustment allows the space above the air cleaner to be utilized while maintaining effective air diffusion into the room.
3Reliability
If magnetic members are added to prevent foreign substances from entering, then reliability is improved, but device complexity increases
Solution Approach 1:
Magnetic members are positioned at the boundary between the internal component space and the external environment (on the upper cover or inlet structure). These magnetic members act as an intermediary protective barrier that prevents foreign substances from entering while requiring minimal additional components compared to mechanical seals or filters.

AI summary
An air cleaner may include a first body having an inlet and an outlet formed above the inlet. The air cleaner may also include a second body disposed above the first body and guiding air discharged from the outlet in a radially outward direction, wherein the second body comprises: a lower cover disposed above the outlet and extending upwardly as it goes in a radially outward direction; a top cover disposed separably to the lower cover; an upper cover disposed between the lower cover and the top cover. The upper cover may include a plate and a protruding cover that protrudes upward from the plate. The top cover may have a hole opened in up-down direction such that the protruding cover is disposed. A groove may be formed at the plate, and the groove may be depressed downward at a periphery of the protruding cover.
