Extraction Cleaner Self-Cleaning Features for Hose and Wand Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extraction cleaners face challenges in maintaining cleanliness and preventing odor buildup in their fluid recovery systems, particularly in hoses and wands, due to the messiness of the cleaning process and the difficulty in keeping these components in good working order.
Innovation Solution
Incorporation of self-cleaning features into accessory tools, wands, and hoses, which divert cleaning fluid into the working air path to flush out debris and odor-causing bacteria, including wand caps, wand receivers, and adapter couplings that create enclosed pathways for fluid diversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional extraction cleaners are used without self-cleaning features, then the cleaning function is simple and device complexity is low, but the recovery system accumulates debris and odor-causing bacteria leading to hygiene deterioration
Solution Approach 1:
The extraction cleaner performs self-cleaning by diverting cleaning fluid through the recovery system to flush out debris and odor-causing bacteria. The system uses its own cleaning fluid to clean itself, eliminating the need for separate manual cleaning processes and maintaining hygiene automatically during normal operation.
Solution Approach 2:
The self-cleaning feature continuously flushes the recovery system during operation, preventing debris and bacteria from accumulating before they can cause hygiene problems. This preliminary cleaning action occurs proactively rather than requiring reactive manual cleaning after contamination occurs.
2Ease of operation
If manual cleaning of the recovery system is performed, then hygiene can be maintained, but the cleaning process is messy and time-consuming
Solution Approach 1:
The system automatically cleans its own recovery system without requiring user intervention. The self-cleaning process eliminates the need for users to manually disassemble, clean, and reassemble components, making maintenance convenient and timeless from the user perspective.
Solution Approach 2:
The manual mechanical cleaning process is replaced by an automated fluid-based cleaning system. Instead of users physically cleaning components, the system uses pressurized cleaning fluid to automatically flush and clean the recovery system, substituting human labor with an automated mechanical process.
3Productivity
If the recovery system is not regularly cleaned, then device complexity remains low, but odor and debris accumulation deteriorates performance
Solution Approach 1:
The recovery system maintains optimal cleaning effectiveness by automatically flushing out debris and bacteria that would otherwise accumulate and degrade performance. This self-maintenance ensures the system continuously operates at peak efficiency without requiring external intervention or complex additional components.
Solution Approach 2:
The self-cleaning feature operates continuously during normal cleaning operations, constantly flushing the recovery system to prevent contamination buildup. This continuous useful action maintains optimal performance throughout operation rather than relying on periodic manual cleaning cycles.
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
Facilitates easy maintenance and cleanliness of extraction cleaner components, reducing mess and odor, and ensuring effective operation by regularly flushing out debris and bacteria from the recovery system.
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
the wand receiver is configured such that an enclosed pathway is formed between the fluid connector and the airflow connector of the wand when the first end of the wand is received by the wand receiver

AI summary
Self-cleaning features for extraction cleaners and attachments for extraction cleaners, such as accessory tools, wands, and/or hoses, are provided. The self-cleaning features are configured redirect cleaning fluid from a fluid supply system of the extraction cleaner into a working air or fluid recovery path of the extraction cleaner, including, but not limited to into the working air or fluid recovery path of a tool, wand, and/or hose of the extraction cleaner.
