Whirling Nozzle Structure for Better Drum Water Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines lack effective mechanisms to enhance washing performance, particularly in distributing and dispersing wash water within the drum to improve cleaning efficiency and laundry absorption.
Innovation Solution
The washing machine incorporates a whirling nozzle with twisted flow paths that transforms wash water into whirling water, dispersing it across the inner surfaces of the drum for efficient spraying and absorption, along with a circulation nozzle to recirculate and atomize water, ensuring thorough laundry soaking and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional spray methods are used to spray wash water into the drum, then the structure is simple, but the washing performance is insufficient due to poor water distribution and dispersion
Solution Approach 1:
The patent employs curved or spiral flow paths within the nozzle structure to generate rotational motion of the water stream. This curvature transforms linear water flow into a whirling pattern, improving water dispersion and coverage on the drum surface without requiring multiple nozzles or complex mechanical components
Solution Approach 2:
The invention utilizes hydraulic principles by designing the nozzle internal flow channels to convert water pressure into rotational kinetic energy. The water flow itself generates the whirling motion through properly designed flow passages, eliminating the need for external mechanical rotation devices while achieving enhanced washing action
2Productivity
If more wash water is sprayed to improve cleaning efficiency, then washing performance increases, but water usage increases
Solution Approach 1:
The whirling nozzle breaks the water stream into finer droplets through rotational motion and centrifugal forces. This segmentation of water into smaller particles increases the total surface area of water contact with laundry, improving cleaning efficiency while using less total water compared to conventional spray methods
Solution Approach 2:
The nozzle transforms the physical parameters of water delivery by changing from a coherent stream to a dispersed whirling spray pattern. This parameter change in flow structure enhances water-laundry interaction efficiency, achieving better cleaning with reduced water quantity
