Pivoting Exhaust Duct Layout for Extractor Surface Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Extractor cleaning machines face inefficiencies in airflow exhaust systems, which hinder effective drying of surfaces after cleaning and may lead to moisture accumulation, affecting the cleaning process and machine performance.
Innovation Solution
The design incorporates a base exhaust duct and a body exhaust duct that cooperate to form an exhaust passageway, allowing airflow generated by the suction source to be directed onto the surface, aiding in drying, and are movable relative to each other as the machine pivots between upright and inclined positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the exhaust system uses a fixed rigid duct configuration, then the structural simplicity is maintained, but the airflow distribution consistency deteriorates when the machine pivots between positions
Solution Approach 1:
The exhaust duct is designed with flexible segments that can dynamically adjust their configuration as the machine pivots between upright and inclined positions. This dynamic flexibility allows the duct to maintain proper airflow alignment and consistent distribution regardless of the machine's orientation, resolving the contradiction between structural simplicity and airflow consistency.
2Device complexity
If the exhaust duct is rigid and fixed, then the device complexity is reduced, but the adaptability to different machine positions deteriorates
Solution Approach 1:
The exhaust duct incorporates flexible joints and movable segments that enable the system to adapt to different machine positions (upright, inclined, etc.) without requiring a completely rigid complex structure. This dynamic design provides adaptability while maintaining reasonable structural simplicity.
Solution Approach 2:
The exhaust duct system uses nested or telescopic segments that can extend and retract or reposition relative to each other as the machine pivots. This nesting principle allows the duct to accommodate various machine positions while avoiding excessive structural complexity.
3Device complexity
If the exhaust outlet is fixed in position, then the structural complexity is minimized, but the surface drying effectiveness deteriorates due to inconsistent airflow distribution
Solution Approach 1:
The exhaust outlet is designed to move or adjust its effective positioning relative to the surface as the machine pivots. This dynamic positioning ensures that the airflow remains consistently directed onto the surface for effective drying, without requiring a complex fixed positioning system.

AI summary
An extractor cleaning machine that includes a base having a base exhaust duct having an exhaust outlet directed toward a surface being cleaned. The extractor further includes a suction source that is operable to generate an airflow that is discharged through the exhaust outlet of the base and onto the surface, which is configured to at least partially dry the surface. The extractor further includes a body pivotally coupled to the base such that the body is pivotable between an upright position and an inclined position, and the body includes a body exhaust duct that is movable relative to the base exhaust duct as the handle pivots between the upright position and the inclined position. The base exhaust duct and the body exhaust duct cooperate to form an exhaust passageway between the suction source and the exhaust outlet.
