Control method of laundry machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry machines face inefficiencies in washing cycles due to issues like uneven laundry distribution, vibration, and noise during high-speed spinning, which affect washing efficiency and user experience.
Innovation Solution
A control method for a laundry machine that includes a water supplying step configured to drive the drum in a scrub motion when water is supplied to the tub, utilizing specific drum driving motions like scrub and step motions to enhance detergent dissolution and laundry wetting, and employing a circulation pump to ensure uniform wetting of laundry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the drum is driven at high speed during spinning, then washing efficiency is improved, but vibration and noise increase
Solution Approach 1:
The drum is driven to rotate in reverse direction at predetermined intervals during high-speed spinning, creating periodic motion that prevents laundry from adhering to the drum wall and reduces vibration and noise while maintaining washing efficiency
Solution Approach 2:
The drum rotation direction is dynamically changed from forward to reverse during the spinning cycle, allowing the system to adaptively control laundry distribution and minimize harmful vibrations while maintaining high washing efficiency
2Use of energy by moving object
If water is supplied to the tub without drum motion, then energy consumption is reduced, but detergent dissolution and laundry wetting are insufficient
Solution Approach 1:
The drum is driven in scrub motion during the water supplying step to preliminarily dissolve detergent and wet laundry uniformly before the main washing cycle, ensuring thorough preparation without excessive energy consumption
Solution Approach 2:
The drum rotation speed and direction are changed during water supply to create scrub motion, optimizing the parameters for detergent dissolution and laundry wetting while maintaining energy efficiency
