Air Conditioner Filter Vibration Cleaning for Quiet Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-conditioners face issues with noise during dust suction, increased volume and manufacturing costs due to separate components for dust removal, and dust scattering during filter cleaning, which affects performance and user safety.
Innovation Solution
An air-conditioner design incorporating a blower fan, a filter with a vibration actuator, and a dust disposal unit that includes a collection part and recovery box, allowing for automatic and quiet dust removal without scattering, using a vibration actuator to separate dust from the filter and a collection roller to guide dust collection and recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a suction nozzle, dust collection part, and motor are used to remove dust from the filter, then dust removal capability is improved, but noise increases and device complexity increases
Solution Approach 1:
The patent applies mechanical vibration by attaching a vibration actuator to the filter to generate vibrations that detach dust particles from the filter surface. This vibration-based cleaning method replaces the need for high-speed suction mechanisms, thereby reducing noise while maintaining effective dust removal capability.
2Productivity
If a suction nozzle, dust collection part, and motor are used to remove dust from the filter, then dust removal capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the dust removal function with the existing filter structure by attaching a vibration actuator directly to the filter. This integration eliminates the need for separate suction nozzles, dust collection parts, and motors, thereby reducing device complexity and manufacturing cost while maintaining dust removal capability.
Solution Approach 2:
The filter performs self-cleaning through the vibration actuator attached to it. The vibration-generated dust detachment occurs directly at the filter surface, and dust falls into the collection space below the filter, enabling the filter to clean itself without requiring additional active components.
3Productivity
If dust is separated from the filter during brush operation, then dust removal is achieved, but dust scatters and causes breakdown of peripheral components or falls to user
Solution Approach 1:
The patent introduces a collection space positioned below the filter as an intermediary structure. This collection space captures dust particles that detach from the filter during vibration, preventing them from scattering to peripheral components or falling to the user. The collection space acts as a controlled intermediate zone that manages dust transport safely.
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 reduces noise and manufacturing complexity, ensures efficient dust collection and recovery, and prevents dust scattering, enhancing user safety and convenience by integrating the dust removal process within the air-conditioner's design.
Implementation Method 1
vibrating a vibration actuator disposed on a side of the filter; and separating the collection part from a lower side of the filter
