Solution Overview
Problem
Traditional extraction cleaners for upholstery and drapes result in extended drying times due to excessive saturation, which is inconvenient for frequent cleaning and can deter users from maintaining cleanliness.
Innovation Solution
An accessory tool with a porous spray bar and suction nozzle system that connects to an extraction cleaner via a hose, allowing for controlled fluid distribution and reduced suction force to minimize surface saturation, ensuring effective cleaning while shortening drying times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional extraction cleaners are used on upholstery and drapes, then cleaning effectiveness is improved, but drying time is excessively extended
Solution Approach 1:
The spray bar is constructed from porous material that distributes cleaning fluid through its porous structure, enabling even distribution at lower flow rates. This porous construction allows the fluid to be applied effectively without saturating the surface, thus maintaining cleaning effectiveness while reducing drying time.
Solution Approach 2:
The invention changes the flow rate parameter of cleaning fluid application to a lower level, and modifies the spray distribution pattern through the porous spray bar. This parameter change enables effective cleaning at reduced fluid application, preventing excessive saturation and thereby reducing drying time.
2Reliability
If high flow rate of cleaning fluid is applied, then cleaning effectiveness is improved, but surface saturation increases leading to longer drying times
Solution Approach 1:
The porous spray bar distributes cleaning fluid through its porous structure, which naturally regulates and limits the quantity of fluid applied to the surface. This prevents excessive saturation while maintaining effective cleaning through even distribution of the reduced fluid quantity.
Solution Approach 2:
The invention applies partial action by using less than the traditional amount of cleaning fluid. The porous spray bar enables effective cleaning with a reduced quantity of fluid, avoiding the excessive saturation that would require extended drying time.
3Loss of time
If cleaning fluid is evenly distributed, then drying time is reduced, but cleaning effectiveness may be compromised
Solution Approach 1:
The porous spray bar inherently provides even distribution of cleaning fluid through its porous structure, which distributes fluid uniformly across the spray area. This even distribution prevents localized saturation and promotes rapid, uniform drying while maintaining cleaning effectiveness through consistent fluid application.

AI summary
An accessory tool usable with an extraction cleaner for cleaning a surface includes a tool body, fluid reservoir, and porous spray bar. The tool body defines a fluid pathway, an airflow pathway, and a suction nozzle connected to the airflow pathway, and connects to the extraction cleaner via an accessory hose. The reservoir is in fluid communication with the fluid pathway and carried by the tool body. The porous spray bar, which is coupled to the tool body adjacent the reservoir and surrounded by the nozzle, directs the cleaning fluid from the reservoir onto the surface. The fluid pathway connects via the hose to a fluid delivery system aboard the extraction cleaner to receive the cleaning fluid and direct the cleaning fluid to the reservoir. The airflow pathway connects the suction nozzle via the hose to a fluid recovery system aboard the extraction cleaner.
