Cylindrical Air Cleaner Layout for 360-Degree Suction and Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners have limited capacity and reliability, with reduced suction capacity due to structural resistance and limited air flow direction, resulting in incomplete air purification in indoor spaces and increased noise from enhanced fan performance.
Innovation Solution
The air cleaner design incorporates multiple blowing devices with cylindrical cases and 360-degree suction ports, a flow adjusting device, and a centrifugal fan to improve suction capacity and direct air flow in various directions, including upward, forward, and lateral directions, while preventing air recirculation and enhancing filter replacement ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fan blowing amount is increased to improve air purification performance, then air purification capacity is improved, but noise increases and reliability decreases
Solution Approach 1:
The patent employs a cylindrical case shape instead of a rectangular parallelepiped, which eliminates corner resistance and enables 360-degree air suction ports around the entire circumference. This curved geometry optimizes airflow patterns, allowing effective air purification with reduced fan power requirements, thus maintaining reliability while improving productivity.
Solution Approach 2:
The invention introduces multi-directional air discharge (upward, forward, and lateral directions) instead of single upward discharge. This three-dimensional air distribution expands the purification coverage throughout the indoor space without requiring increased fan blowing amount, resolving the contradiction between purification capacity and noise/reliability.
2Productivity
If single direction air discharge is used to simplify device structure, then device complexity is reduced, but air purification coverage is limited
Solution Approach 1:
The air discharge function is segmented into multiple independent discharge ports positioned at different locations and orientations (upward discharge port, forward discharge port, lateral discharge ports). Each port handles a specific direction, collectively achieving comprehensive spatial coverage without requiring complex movable or adjustable mechanisms.
3Productivity
If rectangular parallelepiped case shape is used to simplify manufacturing, then ease of manufacture is improved, but suction capacity is reduced due to structural resistance
Solution Approach 1:
The patent adopts a cylindrical case configuration that eliminates the corner resistance inherent in rectangular designs. The curved surface allows uniform 360-degree air suction ports around the entire circumference, maximizing suction capacity. While cylindrical manufacturing may be slightly more complex than rectangular, the design simplifies internal airflow paths and eliminates the need for corner flow management.
4Productivity
If limited direction air suction ports are used to simplify structure, then device complexity is reduced, but suction capacity is limited
Solution Approach 1:
The cylindrical case structure serves multiple functions simultaneously: it provides the structural housing, enables 360-degree air intake through circumferential suction ports, and optimizes airflow patterns. This universal design achieves maximum suction capacity without adding separate complex suction port mechanisms.

AI summary
An air cleaner is provided. The air cleaner may include at least one air cleaning module including a fan, a filter and an inlet through which air is suctioned into the filter; an air flow controller configured to be movably disposed on the at least one air cleaning module and including an air flow control fan to control a flow of the air discharged from the at least one air cleaning module. The air flow controller may be movable from a first position at which the air is discharged in an upward direction to a second position at which the air is discharged in a diagonally upward direction.
