Air cleaner
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 coverage.
Innovation Solution
The air cleaner design incorporates multiple blowing devices with cylindrical cases and 360-degree suction ports, along with a flow adjusting device that allows air to be suctioned from various directions and discharged in multiple directions, including upward, forward, and lateral directions, using centrifugal fans and guide ribs to enhance air flow and reduce noise.
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 air blowing function into multiple independent fans (first blowing fan and second blowing fan) positioned at different locations. This segmentation allows the system to achieve high total airflow without requiring any single fan to operate at high noise-generating speeds, thus maintaining reliability while improving overall purification capacity.
2Ease of manufacture
If a rectangular parallelepiped case is used with limited suction ports, then manufacturing is simplified, but suction capacity is reduced due to structural resistance
Solution Approach 1:
The patent segments the air suction function across multiple surfaces of the case (front surface, rear surface, and side surfaces) with multiple suction ports distributed throughout. This maintains the simple rectangular case structure for ease of manufacture while dramatically increasing suction capacity by eliminating the bottleneck of limited single-direction intake.
3Device complexity
If air is discharged in only one upward direction, then the device structure is simplified, but air cleaning coverage is limited to areas around the air cleaner
Solution Approach 1:
The patent segments the air discharge function into multiple independent discharge ports (first discharge port in upper portion, second discharge port in lower portion) with separate control fans. This allows purified air to be distributed to multiple locations simultaneously, expanding cleaning coverage throughout the indoor space without requiring complex movable or adjustable mechanisms.
4Device complexity
If only one blowing fan is provided, then device complexity is reduced, but blowing capacity is limited and cannot purify entire indoor space
Solution Approach 1:
The patent implements a segmented fan system with multiple blowing fans (first blowing fan coupled to first discharge port, second blowing fan coupled to second discharge port) positioned at different locations and controlled independently. This distributed architecture increases total blowing capacity to handle entire indoor space purification while keeping each individual fan unit simple and manageable.

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.
