Cyclone Module with Elevated Fines Catcher for Simultaneous Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclone modules in vacuum cleaners often have limited space for debris collection due to centrally located fines collectors, which obstruct airflow and hinder effective agglomeration of dust and hair, and require separate emptying processes for bulk and fines collection chambers.
Innovation Solution
The cyclone module design features an elevated fines catcher with independent doors for simultaneous emptying of primary and secondary dirt collection chambers, eliminating the traditional fines collector tube to enhance debris collection space and streamline the emptying process, while incorporating debris management features like tines to prevent re-entrainment and facilitate easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a centrally located fines collector tube is used, then the structure is compact and easier to manufacture, but it obstructs airflow and hinders effective agglomeration of dust and hair
Solution Approach 1:
The patent removes the traditional centrally located fines collector tube from the cyclone chamber. By extracting this obstructive component, the design eliminates airflow interference and allows dust and hair to agglomerate effectively at the center of the cyclone chamber without obstruction, while still providing a means to collect and remove fine particles through an alternative elevated fines catcher design.
Solution Approach 2:
Instead of collecting fines at the bottom center through a vertical tube, the patent positions the fines catcher elevated above the bottom of the cyclone chamber. This spatial repositioning in the vertical dimension allows unobstructed airflow and dust agglomeration at the chamber center while still enabling effective fines collection through gravity-assisted deposition into the elevated catcher.
2Ease of operation
If separate doors are provided for bulk and fines collection chambers, then each chamber can be emptied independently, but the device complexity increases
Solution Approach 1:
The patent combines the emptying functions of both collection chambers into a single door mechanism. The door is configured to simultaneously open access to both the bulk collection chamber and the elevated fines catcher, allowing users to empty both chambers in one operation. This merging approach maintains independent emptying capability while reducing mechanical complexity by eliminating the need for separate door assemblies.
3Device complexity
If the fines collection chamber bottom is at the same level as bulk collection chamber, then the structure is simpler, but it reduces debris collection capacity in the primary chamber
Solution Approach 1:
The patent positions the fines collection chamber elevated above the bottom of the bulk collection chamber rather than at the same level. This vertical displacement creates additional space at the bottom of the bulk collection chamber for increased debris capacity, while the elevated fines catcher maintains its collection function through gravity-assisted particle deposition from the cyclone separation process.

AI summary
A cyclone module (36, 126, 206) for a vacuum cleaner includes a primary separator (40, 130, 210), a bulk collection chamber (42, 132, 212), at least one secondary separator (44, 148, 228) and a fines collection chamber (46, 154, 244). First and second doors (50, 120, 136, 200, 216, 252) are provided for closing debris outlets at the bottom ends of the bulk and fines collection chambers, respectively. The fines collection chamber (46, 154, 244) is elevated within the bulk collection chamber (42, 132, 212), with the second door (120, 200, 252) spaced above the first door (50, 136, 216).
