Cyclone Module Layout for Compact Vacuum Dust Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cyclone separators in vacuum cleaners face challenges in efficiently separating dust and debris, particularly in preventing debris re-entrainment and maintaining stability, especially in canister vacuum cleaners where space and height are critical.
Innovation Solution
A cyclone module with a separation chamber and a debris outlet positioned adjacent to a dust collection chamber, featuring a removable exhaust grill with a ramp for directing air in a helical path and a filter assembly for further cleaning, which guides debris into a dust collection chamber, enhancing separation efficiency and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cyclone separation chamber is positioned above the dirt collection chamber in a vertically stacked orientation, then the separation efficiency is improved, but the overall height of the cyclone module increases
Solution Approach 1:
The patent transitions from a vertical stacking arrangement to a horizontal adjacent arrangement of the cyclone separation chamber and dirt collection chamber. This dimensional change allows the modules to be positioned side-by-side rather than one above the other, reducing the overall height while maintaining separation functionality through the horizontal debris outlet pathway.
2Stability of the object's composition
If the exhaust grill is fixed in the separation chamber, then the structural stability is improved, but the ease of cleaning deteriorates
Solution Approach 1:
The exhaust grill is designed as a separable component that can be removed from the separation chamber. This segmentation allows the grill to be detached for cleaning purposes while maintaining structural stability when installed. The grill connects to the cyclone outlet through a removable interface that preserves structural integrity during operation but enables easy removal for maintenance.
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 separates dust and debris, reduces the risk of re-entrainment, and improves the stability and compactness of canister vacuum cleaners by optimizing the cyclone module's design and airflow path.
Implementation Method 1
Some cyclone separators follow textbook examples using frusto-conical shape separators and others use high-speed rotational motion of the air/dirt to separate the dirt by centrifugal force
Implementation Method 2
A vacuum fan/motor mounted in the cleaner body has a suction inlet in communication with the inlet port and adapted to maintain a flow of dirty air from the inlet port through the cyclone separation chamber
