Self-Cleaning Air Conditioner Filter With Adjustable Suction Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioner filters require regular cleaning and replacement, which is inconvenient for users, and their suction power decreases when filled with impurities, affecting air purification efficiency.
Innovation Solution
An air conditioner with a suction nozzle, suction duct, and screening member that automatically cleans the filter by suctioning foreign materials and adjusting the suction space to maximize cleaning efficiency and prevent vibration-induced detachment of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the filter operates continuously without cleaning, then air purification continues, but suction power decreases and cleaning efficiency drops
Solution Approach 1:
The suction nozzle performs preliminary cleaning actions on the filter surface by suctioning foreign materials before they significantly accumulate and block air flow. The cleaning operation is initiated periodically or based on usage time, preventing suction power degradation rather than addressing it after occurrence.
2Quantity of substance
If the suction space volume is large, then more foreign materials can be collected, but suction power is diluted and cleaning efficiency decreases
Solution Approach 1:
The suction space is designed with specific localized dimensions that concentrate suction power on the filter surface area requiring cleaning. The space volume is optimized to match the filter size, ensuring that the suction force is applied precisely where foreign materials accumulate, rather than dispersing over a large volume.
3Reliability
If the screening member is firmly fixed to prevent detachment, then reliability improves, but replacement difficulty increases
Solution Approach 1:
The screening member is designed as a separate, detachable component from the suction nozzle and suction duct. This segmentation allows the screening member to be firmly fixed during operation (preventing detachment from vibration) while enabling easy removal and replacement when damaged or clogged, without requiring replacement of the entire suction assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances suction power by focusing it only on relevant areas, maximizing cleaning efficiency and allowing for easy replacement of damaged parts, thus maintaining air purification effectiveness without frequent filter maintenance.

AI summary
An air conditioner is provided. The air conditioner includes: a body defining an air suction port; a filter filtering air suctioned through the air suction port; a suction nozzle suctioning foreign materials of the filter and moving with respect to the filter; a suction duct into which the foreign materials suctioned through the suction nozzle flow; a screening member forming a suction space in relationship with the suction duct; and a space adjustor disposed on the suction space to adjust a volume of the suction space.
