Cyclone Module with Elevated Fines Chamber for One-Step Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 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 a separate door that automatically opens when vacuum pressure ceases, allowing simultaneous emptying of primary and secondary dirt collection chambers, and incorporates debris management tines to prevent re-entrainment and clogging, eliminating the need for a traditional fines collector tube and enhancing airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a centrally located fines collector tube is used, then fines separation is achieved, but it obstructs airflow and hinders agglomeration of dust and hair
Solution Approach 1:
The patent removes the traditional centrally located fines collector tube from the cyclone chamber. Instead, fines are collected in a separate chamber positioned above the bulk collection chamber, eliminating the obstruction to airflow and agglomeration processes in the cyclone chamber while maintaining effective fines separation capability.
Solution Approach 2:
The patent relocates the fines collection function from a vertical central tube to a horizontal chamber positioned above the bulk collection chamber. This dimensional repositioning allows fines collection without interfering with the vertical airflow patterns and agglomeration processes in the cyclone chamber.
2Manufacturing precision
If separate chambers for bulk and fines collection are used, then debris classification is improved, but the device complexity increases
Solution Approach 1:
The patent combines the bulk collection chamber and fines collection chamber into a single integrated cyclone module with a unified housing. The two chambers are positioned vertically (bulk below, fines above) and share common structural elements, achieving effective debris classification while maintaining a compact and simple overall structure.
Solution Approach 2:
The fines collection chamber is positioned within the upper portion of the cyclone module housing, with the bulk collection chamber below it. The chambers are nested vertically within the same housing structure, allowing compact integration without requiring separate external chambers.
3Quantity of substance
If traditional separate emptying processes are used for bulk and fines chambers, then complete debris removal is achieved, but the ease of operation decreases
Solution Approach 1:
The patent provides a single access point at the bottom of the bulk collection chamber that allows simultaneous emptying of both the bulk collection chamber and the fines collection chamber. When the bottom wall is opened, debris from both chambers can be removed in one operation, eliminating the need for separate emptying processes while ensuring complete debris removal.

AI summary
A cyclone module for a vacuum cleaner includes a primary separator, a bulk collection chamber, at least one secondary separator and a fines collection chamber. First and second doors are provided for closing debris outlets at the bottom ends of the bulk and fines collection chambers, respectively. The fines collection chamber is elevated within the bulk collection chamber, with the second door spaced above the first door.
