Self-cleaning features for extraction cleaners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Extraction cleaners face challenges in maintaining the cleanliness of their fluid recovery systems, leading to residue buildup and unpleasant odors in hoses and attachments, which complicates post-use maintenance.
Innovation Solution
Incorporating self-cleaning features such as wand caps, wand receivers, accessory tools, and adapter couplings that divert cleaning fluid into airflow paths to flush out debris and residue from wands, hoses, and recovery systems, allowing for easy cleaning and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional extraction cleaners are used without self-cleaning features, then the basic cleaning function is maintained, but residue buildup and odors occur in hoses and attachments requiring complicated post-use maintenance
Solution Approach 1:
The system enables self-cleaning by allowing cleaning solution to be diverted into the airflow pathway, automatically flushing debris and residue from the hose and attachments without requiring manual disassembly or separate cleaning procedures
Solution Approach 2:
The system recovers cleaning solution and redirects it through the airflow pathway to flush out accumulated debris and residue from the hose and attachments, converting waste cleaning fluid into a useful cleaning agent for maintenance
2Object-generated harmful factors
If self-cleaning features are incorporated into extraction cleaners, then cleaning fluid can be diverted into airflow paths to flush debris and residue, but the device complexity increases with additional pathways and connectors
Solution Approach 1:
The cleaning solution delivery system serves dual functions: it delivers cleaning solution to the surface during normal operation and redirects the same solution into the airflow pathway for self-cleaning, eliminating the need for separate cleaning mechanisms
Solution Approach 2:
The system merges the cleaning solution delivery system with the airflow pathway by providing a diverter mechanism that redirects cleaning solution into the existing air conduit, combining two functions into integrated pathways
3Productivity
If cleaning fluid is delivered continuously to the surface, then effective cleaning is maintained, but no cleaning fluid is available to flush the recovery system and attachments
Solution Approach 1:
The system dynamically switches the flow path of cleaning solution between two modes: delivering to the surface during normal cleaning operations and redirecting into the airflow pathway for self-cleaning, allowing the system to adapt its function based on operational needs

Function Achieved in This Case
These self-cleaning features effectively remove debris, residue, and odor-causing bacteria from extraction cleaner components, improving user experience by simplifying the cleaning process and maintaining the efficiency of the equipment.
Implementation Method 1
a source of suction in fluid communication with the working air conduit to draw the cleaning fluid from the surface to be cleaned and through the nozzle and the working air conduit to the recovery tank
Implementation Method 2
divert cleaning fluid into airflow paths to flush out debris and residue from wands, hoses, and recovery systems
