Air Conditioner Filter Cleaning with Self-Cleaning Dust Brushes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter cleaning devices for air conditioners suffer from reduced efficiency due to dust accumulation on brushes, leading to obstructed airflow and performance degradation, affecting both air conditioners and other equipment with filters.
Innovation Solution
A filter cleaning device with a movable filter that includes a first dust elimination member and a second dust elimination member, where the first member is rotated to contact the second member to remove dust, and a dust elimination cover to prevent re-contamination, enhancing dust collection and removal efficiency without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a brush is used to continuously clean the filter, then dust is removed from the filter, but dust accumulates on the brush reducing cleaning efficiency
Solution Approach 1:
The dust elimination function is divided into two separate members: the first dust elimination member (brush) that removes dust from the filter, and the second dust elimination member that removes dust from the first member. This segmentation prevents dust accumulation on a single component, maintaining continuous cleaning efficiency.
Solution Approach 2:
The second dust elimination member continuously removes and eliminates dust that accumulates on the first dust elimination member. This ensures the first member remains clean and effective, preventing performance degradation from dust accumulation.
2Device complexity
If dust is not eliminated from the first dust elimination member, then cleaning structure is simple, but dust re-contaminates the filter reducing cleaning effectiveness
Solution Approach 1:
The dust elimination system is segmented into two functional members with distinct roles. The first member handles primary filter cleaning while the second member handles secondary cleaning of the first member, preventing re-contamination without requiring a complex single-component system.
Solution Approach 2:
The second dust elimination member operates continuously to remove dust from the first member, ensuring uninterrupted cleaning effectiveness. This continuous action prevents dust re-contamination of the filter, maintaining constant cleaning performance.
3Device complexity
If the filter is stationary, then structure is simple, but dust accumulates on the filter blocking airflow
Solution Approach 1:
The filter is made movable rather than stationary, allowing it to be reciprocally moved between cleaning positions. This dynamic design enables the filter to contact the first dust elimination member during movement, facilitating continuous dust removal while maintaining simple overall structure.
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 effectively eliminates dust from filters, improving cleaning efficiency and maintaining air conditioner performance by ensuring continuous dust removal without manual intervention.
Implementation Method 1
the first dust elimination member is reversely rotated with respect to a movement direction of the filter to come in contact with the second dust elimination member, thereby eliminating the dust collected at the first dust elimination member

AI summary
An air conditioner including a suction inlet configured to suction air, a filter movably arranged at one side of the suction inlet, a first dust elimination member provided within a movement section of the filter to eliminate dust thereof by coming in contact with the filter when the filter is moved and a second dust elimination member provided adjacent to one side of the first dust elimination member to eliminate dust collected at the first dust elimination member, wherein the first dust elimination member is reversely rotated with respect to a movement direction of the filter to come in contact with the second dust elimination member, thereby eliminating the dust collected at the first dust elimination member.
