Steam Vacuum Cleaner Cyclone Separation for Dry Debris Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination steam and vacuum surface cleaning apparatuses often operate the vacuum and steam functions separately to avoid collecting liquid and dry debris simultaneously, leading to inefficient cleaning and cumbersome operation.
Innovation Solution
A combination steam and vacuum surface cleaning apparatus that includes a vacuum collection system, a cyclonic separating and collection assembly, a liquid distribution system, and a steam generation system, allowing concurrent operation of steam delivery and suction to collect debris and liquid while keeping the collection chamber dry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If steam generator and suction source operate concurrently, then cleaning efficiency is improved, but liquid mixes with debris in the collection chamber
Solution Approach 1:
The collection system is divided into separate functional zones: a cyclone separation chamber for debris-liquid separation and a collection chamber for dry debris storage. The cyclone chamber uses centrifugal force to separate liquid from debris, directing liquid to a drainage system while collecting dry debris in the collection chamber. This segmentation prevents liquid contamination of the collected debris while maintaining concurrent steam and vacuum operation.
Solution Approach 2:
The cyclone separator acts as an intermediary component between the suction nozzle and the collection chamber. It mediates the separation process by using centrifugal force to divide the incoming air-debris-liquid mixture into separate streams: dry debris is directed to the collection chamber while liquid is channeled to the drainage system. This intermediary mechanism enables concurrent operation without mixing liquid and debris in the collection chamber.
2Productivity
If vacuum function operates to collect liquid and debris, then cleaning capability is improved, but collection chamber becomes wet and requires emptying
Solution Approach 1:
The liquid is extracted from the air-debris mixture in the cyclone separation chamber and removed from the system through a drainage system. By separating and removing the liquid component before debris collection, the collection chamber receives only dry debris, eliminating the need for users to empty wet collections and reducing maintenance effort.
Solution Approach 2:
The system uses pneumatic principles through the cyclone separator, which utilizes centrifugal force generated by rotating airflow to separate liquid from debris. The hydraulic design of the drainage system efficiently channels separated liquid away from the collection chamber, enabling automatic liquid removal and keeping the collection chamber dry during operation.
3Productivity
If steam is delivered to surface, then cleaning effectiveness is improved, but liquid is drawn into suction nozzle
Solution Approach 1:
The cyclone separator is positioned in the working airstream path before the collection chamber, performing preliminary separation of liquid from the air-debris mixture. This preliminary action removes liquid from the airstream early in the process, preventing liquid accumulation in the collection chamber while allowing the steam cleaning function to operate effectively on the surface.

AI summary
A surface cleaning apparatus comprises a steam generation system for producing steam from liquid, a liquid distribution system for storing liquid and delivering the liquid to the steam generation system, a steam delivery system for delivering steam to a surface to be cleaned, and a vacuum collection system which can be operated concurrently with the other systems. The surface cleaning apparatus can comprise an upper housing mounted to a lower cleaning foot which is adapted to be moved across a surface to be cleaned.
