Cyclone Module Layout for Simultaneous Dust and Fines 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, complicating debris disposal.
Innovation Solution
The cyclone module design features an elevated fines catcher with a separate door that empties both primary and secondary dirt collection chambers simultaneously, eliminating the traditional fines collector tube to enhance airflow and agglomeration, and incorporates debris management features like tines to prevent re-entrainment and facilitate easy emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement 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 spatial reconfiguration allows airflow to move freely through the cyclone chamber without obstruction, while fines are still effectively separated and collected in the elevated chamber.
2Reliability
If separate emptying processes are used for bulk and fines collection chambers, then complete debris removal is achieved, but debris disposal complexity increases
Solution Approach 1:
The patent merges the emptying operations of the bulk collection chamber and fines collection chamber into a single unified process. By positioning the fines collection chamber above the bulk collection chamber with aligned openings, both chambers can be emptied simultaneously through one door operation, significantly simplifying the debris disposal process while ensuring complete removal of all debris types.
3Quantity of substance
If a traditional fines collector tube is used, then fines are collected, but it obstructs the bottom tank and reduces debris collection space
Solution Approach 1:
The patent extracts the fines collection function from the bottom tank area by relocating it to an elevated chamber positioned above the bulk collection chamber. This removal of the central obstruction significantly increases the usable volume of the bottom tank for bulk debris collection while maintaining effective fines collection capability in the separate elevated chamber.
4Ease of operation
If an elevated fines catcher with separate door is used, then simultaneous emptying is achieved, but structural complexity increases
Solution Approach 1:
The patent combines the door mechanisms of the bulk collection chamber and fines collection chamber into a single integrated door system. The unified door provides simultaneous access to both chambers, allowing one operational action to empty both chambers at once. This integration simplifies the user interface and operation while the internal structure maintains separate collection spaces for different debris types.
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
This design increases debris collection space in the bulk chamber, improves airflow by reducing turbulence, and allows for simultaneous emptying of all collected dirt without obstructing the bottom tank, providing a more efficient and user-friendly debris disposal process.
Implementation Method 1
others use high-speed rotational motion of the air/dirt to separate the dirt by centrifugal force
Implementation Method 2
improves airflow by reducing turbulence, and allows for simultaneous emptying of all collected dirt without obstructing the bottom tank

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.
