Drum Washer Whirling Nozzle for Uniform Water Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drum washing machines face limitations in achieving optimal washing performance due to inefficient water distribution and laundry attachment during the washing process, leading to subpar cleaning and potential damage to garments.
Innovation Solution
The implementation of a washing machine design featuring a whirling nozzle that changes supplied wash water into whirling water, allowing for efficient spraying onto the inner surfaces of the drum, combined with a circulation nozzle for effective water circulation, ensures thorough laundry contact and improved washing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the drum rotates at high speed to attach laundry to the drum wall, then washing efficiency is improved through better water distribution, but water penetration into laundry becomes insufficient
Solution Approach 1:
A water spray nozzle is introduced as an intermediary device to deliver water directly to the laundry on the drum wall. The nozzle receives water from the water supply and sprays it onto the laundry surface, mediating between the water supply system and the laundry to ensure adequate water penetration even during high-speed rotation when centrifugal force prevents natural water absorption
2Productivity
If more wash water is supplied to improve washing performance, then cleaning effectiveness increases, but water consumption increases
Solution Approach 1:
Instead of uniformly distributing water throughout the drum, the water spray nozzle applies water locally and directly to the laundry surface where it is needed. This localized water application ensures effective washing performance while minimizing overall water consumption by avoiding unnecessary water in areas where laundry is not present
3Device complexity
If conventional water spraying is used, then the structure remains simple, but water distribution uniformity is poor
Solution Approach 1:
The system utilizes the dynamic rotation of the drum to achieve uniform water distribution. The water spray nozzle remains stationary while the drum rotates, bringing different portions of laundry sequentially past the spray point. This dynamic interaction between the stationary nozzle and rotating drum ensures all laundry receives water uniformly without requiring a complex multi-nozzle system
