Low-Profile Cleaning Diffuser for Dynamic Pressure Fluff Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning diffusers for fluff-laden components in domestic appliances, such as heat exchangers, are too tall and inefficient in distributing rinsing fluid to detach fluff, as they rely on a three-dimensional configuration that increases height and affects dynamic pressure generation.
Innovation Solution
A diffuser design with two parallel feed ducts that terminate in a barrier, featuring a narrow three-dimensional transverse connection and outlet openings, allowing dynamic pressure buildup without increasing height, ensuring effective fluff removal with a low-profile design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a three-dimensional configuration is used to generate dynamic pressure in the cleaning fluid, then the cleaning effectiveness is improved, but the height of the diffuser increases
Solution Approach 1:
The patent transitions from a three-dimensional configuration to a substantially two-dimensional planar structure. The feed ducts are arranged parallel to each other in the same plane, with the transverse connection occurring in the plane of the outlet opening, thereby eliminating the need for vertical stacking and reducing the height dimension while maintaining dynamic pressure generation capability
Solution Approach 2:
The cleaning fluid flow is divided into two separate parallel feed ducts that run alongside each other. This segmentation allows the system to maintain effective flow distribution and dynamic pressure generation while arranging components in a compact planar configuration rather than requiring vertical space
2Power
If the diffuser is designed with sufficient height to accommodate three-dimensional flow structures, then dynamic pressure generation is improved, but the space required in the appliance increases
Solution Approach 1:
The patent reconfigures the flow paths from three-dimensional vertical structures to two-dimensional planar arrangements. The parallel feed ducts and transverse connection are all arranged in substantially the same plane, enabling dynamic pressure generation without increasing the vertical footprint or overall volume of the diffuser component
Solution Approach 2:
The patent changes the geometric parameters of the flow paths by flattening them into a planar configuration. The feed ducts have controlled cross-sectional areas and the transverse connection provides a narrow passage, all arranged in the same plane to generate dynamic pressure while maintaining a compact form factor

Function Achieved in This Case
The diffuser effectively distributes rinsing fluid to detach fluff from components with a high-speed, elongated stream, achieving efficient cleaning while maintaining a low height, suitable for various appliance configurations.
Implementation Method 1
it being possible for dynamic pressure to build in the rinsing fluid in the diffuser
Implementation Method 2
the diffuser has an internal structure such as a cross-sectional constriction in order to generate dynamic pressure in the cleaning fluid

AI summary
A cleaning diffuser is disposed above a fluff-laden component and receives rinsing fluid for distributing the rinsing fluid to the fluff-laden component to detach fluff and carry it away. The diffuser is constructed to enable a buildup of dynamic pressure in the rinsing fluid and has two feed ducts which extend at a distance from one another in substantially parallel relationship so that rinsing fluid entering the diffuser is divided between the feed ducts. The feed ducts terminate in pockets in a wall at an end of the diffuser and have, relative to their entire duct length, a narrow, three-dimensional transverse mutual connection in the form of a transverse chamber. The diffuser has at least one narrow outlet opening which extends from the three-dimensional transverse connection to a lower side of the diffuser for distributing the rinsing fluid to the fluff-laden component.
