Multi-Cyclone Dust Collector Layout to Prevent Suction Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges in efficiently collecting foreign matter, dust, and fine dust due to interference between cyclones, which reduces suction power and cleaning performance, and issues with dust floating back in the collector.
Innovation Solution
A vacuum cleaner design where the second cyclone is accommodated within the first cyclone, eliminating the need for guide passages and allowing for a larger number of second cyclones, enhancing suction power and preventing dust backflow through a guide unit and pressurizing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a second cyclone is provided within a first cyclone, then the height of the dust collector is reduced, but the number of second cyclones significantly decreases, reducing suction power
Solution Approach 1:
The second cyclone is accommodated within the first cyclone in a nested configuration, allowing multiple cyclones to be arranged in a compact space without significantly increasing the overall height of the dust collector
Solution Approach 2:
The cyclones are arranged in a horizontal plane rather than vertically stacking them, transitioning from vertical space utilization to horizontal space utilization, thereby maintaining compact height while accommodating multiple cyclones
2Length of stationary object
If the dust collector is designed with a slim profile, then the height is reduced, but the volume of space for collecting dust is reduced
Solution Approach 1:
The dust collection space is expanded in the horizontal direction rather than vertically, utilizing radial and horizontal space within the cyclone structure to maintain a compact height while providing sufficient dust collection volume
3Quantity of substance
If multiple cyclones are arranged with guide passages, then separation is achieved, but interference between guide passages reduces cleaning performance
Solution Approach 1:
The guide passages are eliminated from the cyclone structure, extracting the flow guidance function from the cyclone design to prevent interference between adjacent cyclones while maintaining effective dust separation
Solution Approach 2:
A partition wall is introduced as an intermediary structure between adjacent cyclones, preventing flow interference and maintaining independent operation of each cyclone without requiring complex guide passages

Function Achieved in This Case
This design improves suction efficiency, maintains cleaning performance, and reduces dust backflow by ensuring efficient separation and collection of foreign matter and fine dust.
Implementation Method 1
a vacuum cleaner configured to collect foreign matter, dust and fine dust in a separate manner through a multi-cyclone
Implementation Method 2
a variety of flows including a high-speed rotation flow due to the suction power of a fan module are mixed within a dust collector
Implementation Method 3
uses suction power to filter and collect foreign matter, e.g., debris, dust, fine dust, ultra fine dust and the like contained in the sucked air

AI summary
A vacuum cleaner, including a cleaner body; and a dust collector provided in the cleaner body, wherein the dust collector includes a first cyclone provided within an outer case to filter foreign matter and dust from air introduced into the dust collector; a second cyclone accommodated within the first cyclone to separate fine dust from the air introduced into the first cyclone; a screw provided at a lower side of and surrounding the first cyclone, and having at least one vane spirally extended along a flow direction of the air introduced into the outer case to induce the inflow of foreign matter and dust filtered by the first cyclone into a first storage section.
