Air Cleaner Airflow Structure for 360-Degree Suction Coverage
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 require user movement to achieve desired air purification.
Innovation Solution
The air cleaner design incorporates multiple blowing devices and a flow adjusting device with a cylindrical shape and radial suction ports, allowing 360-degree air suction and directional air discharge, enhancing suction capacity and air flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the blowing amount of the fan is increased to improve air purification performance, then the purification capacity is improved, but noise generated by the fan increases and reliability decreases
Solution Approach 1:
The patent divides the single fan system into multiple blowing fans (first blowing fan and second blowing fan). Each fan handles a portion of the air purification task, allowing the system to achieve high purification capacity without requiring any single fan to operate at excessively high speeds that would generate noise and reduce reliability.
2Ease of manufacture
If a rectangular parallelepiped case is used for structural simplicity, then manufacturing is easier, but suction capacity is reduced due to structural resistance at corner portions
Solution Approach 1:
The patent introduces curved guide surfaces and rounded air flow paths within the rectangular case structure. The guide ribs and curved surfaces at the corner portions redirect air flow smoothly, reducing turbulence and structural resistance caused by sharp corners, thereby improving suction capacity while maintaining the simple rectangular external form.
3Device complexity
If air suction ports are limited to side and lower portions, then device complexity is reduced, but suction capacity is reduced due to limited suction directions
Solution Approach 1:
The patent makes the case structure itself serve multiple functions: it provides structural enclosure and simultaneously acts as an air suction port through through-holes formed in the case. This allows air to be sucked from multiple directions (side, lower, and upper portions) without adding separate complex inlet structures, thereby increasing suction capacity while keeping the device simple.
4Device complexity
If air discharge is limited to upward direction only, then device complexity is reduced, but air cleaning function is limited as purified air does not reach distant spaces
Solution Approach 1:
The patent adds lateral air discharge capability to the existing upward discharge function. The second blowing fan discharges air in a lateral direction through a separate discharge port, creating a multi-directional discharge system. This expands the coverage area of purified air throughout the indoor space without significantly increasing device complexity.
5Device complexity
If a single blowing fan is used to simplify the device, then device complexity is reduced, but blowing capacity is limited and cannot purify entire indoor space
Solution Approach 1:
The patent divides the air blowing function into multiple independent fans (first blowing fan for upward discharge, second blowing fan for lateral discharge). Each fan is responsible for a specific discharge direction and zone, collectively achieving comprehensive indoor space purification with higher total blowing capacity while maintaining manageable device complexity.

AI summary
An air flow controller for an air cleaner and an air cleaner are provided. The air flow controller may include a fan, and a housing, the fan being provided in the housing and the housing being movable from an initial horizontal position in which the air flow controller directs air flow in a vertical direction to an inclined position in which the air flow controller directs air flow in a diagonal direction.
