Cleaner Movable Frame Design for Dust Compression and Airflow Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face inefficiencies in dust compression and air guidance due to the design of the dust compression part, which reduces the internal space for dust separation and can cause dust to be caught between the compression part and the dust bin's inner surface, leading to reduced performance and smooth movement issues.
Innovation Solution
A cleaner design featuring a movable frame that surrounds the cyclone flow axis, with a guide wall to direct air and dust, and a cleaning part aligned with the suction opening, allowing for smooth airflow and preventing dust from entering gaps between moving parts, thus enhancing dust compression and separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the dust compression part is located higher than the opening at standby position, then the dust compression part can be accommodated in the dust bin, but the internal space of the dust bin is reduced and dust separation space is reduced
Solution Approach 1:
The movable part is segmented into distinct functional components: a frame structure, a guide wall for airflow direction, and a cleaning part. This segmentation allows each component to perform its specific function without interfering with others, maximizing the dust bin internal space while maintaining dust separation performance.
Solution Approach 2:
The guide wall is designed to extend in the airflow direction, creating a three-dimensional airflow guidance structure. This dimensional approach directs air and dust along a controlled path, preventing dust from entering gaps between components while maintaining adequate dust separation space within the bin.
2Ease of operation
If the dust compression part moves in contact with the inner circumferential surface of the dust bin, then the inner circumferential surface can be cleaned, but dust may be caught between the dust compression part and the inner circumferential surface causing movement issues
Solution Approach 1:
The guide wall acts as an intermediary structure between the airflow and the dust bin inner surface. It directs air and dust along a controlled path, preventing dust from being trapped between the movable cleaning part and the dust bin surface, thereby ensuring smooth movement while maintaining cleaning capability.
Solution Approach 2:
The guide wall is designed with curved surfaces that guide airflow smoothly around the dust bin interior. These curved surfaces prevent dust accumulation in sharp corners or gaps, allowing the cleaning part to move smoothly along the inner circumferential surface without catching dust.
3Productivity
If the frame is disposed to face the suction opening at the first position, then air and dust can be guided effectively, but the upper end of the frame may allow dust to enter gaps between components
Solution Approach 1:
The guide wall is positioned to preliminarily direct air and dust along a controlled path before they reach the movable frame components. This preliminary airflow direction prevents dust from entering gaps between components, maintaining both guidance efficiency and component protection.
Solution Approach 2:
The frame is designed to be movable between different positions, allowing it to dynamically adjust its configuration. At the first position, it faces the suction opening for effective air and dust guidance; the guide wall ensures dust does not enter gaps during this dynamic operation.
