Movable Filter Cleaner for Automatic Air Conditioner Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioners require frequent filter cleaning and replacement, which is inconvenient and can lead to reduced performance and potential damage due to the lack of automatic cleaning mechanisms, making it difficult for users to maintain the filters effectively.
Innovation Solution
An air conditioner design that includes a filter cleaner kit with movable kit cases and suction force generation units, allowing for automatic cleaning of filters without separating them from the unit, using agitators and cyclones to collect and separate alien substances, and a damper system to control suction force distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is detachably installed to enable replacement and cleaning, then the filter can be replaced or cleaned, but the installation position and method are restricted and the layout of peripheral components is limited
Solution Approach 1:
The filter cleaner kit enables automatic self-cleaning of the filter without requiring user disassembly or manual cleaning operations. The suction force generation unit automatically draws dust and debris from the filter surface, allowing the filter to clean itself while remaining installed in the air conditioner, thus eliminating the trade-off between ease of cleaning and installation flexibility
Solution Approach 2:
The filter cleaner kit acts as an intermediary device between the filter and the user. Instead of the user directly handling filter removal and cleaning, the automated cleaner kit mediates the cleaning process by introducing suction force to remove contaminants, thereby simplifying user operation while maintaining flexible filter installation
2Ease of operation
If the filter is cleaned manually by the user, then the filter can be cleaned, but the process is inconvenient and reduces the sensitivity quality of the air conditioner
Solution Approach 1:
The filter cleaner kit enables the filter to clean itself automatically through the suction force generation unit that draws dust and debris from the filter surface. This self-service mechanism eliminates the need for manual user intervention, significantly improving convenience and automation level while maintaining effective filter cleaning
Solution Approach 2:
The manual mechanical cleaning process is replaced by an automated pneumatic system. Instead of users physically removing and washing filters, the suction force generation unit uses air flow to automatically remove contaminants, substituting manual mechanical action with an automated pneumatic mechanism
3Productivity
If the filter is not cleaned regularly, then the air conditioner can operate without maintenance, but the accumulated alien substances interrupt air flow and deteriorate the function of the air conditioner
Solution Approach 1:
The filter cleaner kit enables continuous maintenance of filter performance by automatically removing accumulated dust and debris. This continuous cleaning action prevents air flow interruption and maintains the air conditioner's function, allowing the system to operate continuously at optimal performance without periodic maintenance shutdowns
Solution Approach 2:
The system provides automatic feedback-based cleaning by continuously monitoring filter contamination levels and activating the suction force generation unit when cleaning is needed. This feedback mechanism ensures the filter is cleaned at appropriate intervals, maintaining reliable air flow and system function without requiring user intervention or system shutdown
4Productivity
If a movable suction nozzle is used to remove dust from the filter, then dust can be removed, but the structure for moving the cleaner kit is complex
Solution Approach 1:
The filter cleaner kit uses pneumatic principles through the suction force generation unit to remove dust from the filter. Instead of complex mechanical moving structures, the system employs air flow to transport dust and debris from the filter surface to the collection container, achieving effective dust removal with a simpler pneumatic-based structure
