Dryer Diffuser Layout for Uniform Vertical Flushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dryer cleaning methods, such as those using condensate for flushing, result in non-uniform cleaning of lint-loaded components due to horizontal flow components, leading to incomplete cleaning and potential long-term contamination.
Innovation Solution
A device with a diffuser having a distribution channel and an overflow area, where the flushing medium is directed vertically downwards, ensuring uniform flow distribution across the component, utilizing a one-piece design to prevent assembly tolerances and enhance flow directionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the flushing medium is supplied laterally to the diffuser, then the diffuser can be positioned above the component, but the flow direction has a large horizontal component resulting in non-uniform flow distribution and incomplete cleaning
Solution Approach 1:
The patent changes the flow direction from horizontal to vertical by repositioning the inlet opening at the bottom of the diffuser instead of laterally. This dimensional change in flow direction eliminates the large horizontal flow component and achieves uniform vertical flow distribution across the component surface, resolving the cleaning uniformity issue
2Productivity
If a conventional diffuser design is used with lateral inlet, then the structure is simple, but the cleaning effectiveness is reduced due to non-uniform flow distribution
Solution Approach 1:
The patent inverts the conventional diffuser design by placing the inlet opening at the bottom instead of laterally at the top or side. This inversion of the inlet position causes the flushing medium to flow upward and then distribute vertically downward, creating uniform flow distribution and significantly improving cleaning effectiveness
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
This configuration achieves significantly improved cleaning by ensuring all areas of the component are flushed uniformly, preventing spillage and ensuring complete removal of fluff, thus enhancing the overall cleaning effectiveness.
Implementation Method 1
an overflow area which is fluidically coupled to the distribution channel and with which the flushing medium can be directed downwards to the component in the vertical direction of flow
