Solution Overview
Problem
High-speed rotary drum washing machines are prone to vibration and shifting due to unstable laundry center of gravity, which can lead to water pipe disconnection and potential injury, affecting washing efficiency and machine performance.
Innovation Solution
A washing control method that acquires the laundry load, determines an eccentricity threshold, and switches between a first and second washing mode based on the eccentricity to ensure stable operation, using a weighing device to detect load and motor parameters to adjust rotation speed accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the inner drum rotates at high speed to achieve high-speed rotary drum washing, then the washing efficiency is improved, but the washing device is prone to vibration and shift due to unstable laundry center of gravity
Solution Approach 1:
The system performs preliminary detection of laundry load and eccentricity before entering high-speed washing mode. The control unit detects the laundry load in the inner drum and determines whether the laundry is in a balanced state before allowing the washing machine to operate at high speed, preventing vibration and shift issues before they occur
Solution Approach 2:
The system continuously monitors the eccentricity of the laundry during operation and provides feedback to the control unit. Based on the detected eccentricity values compared against threshold values, the control unit adjusts the washing mode or speed to maintain stable operation, creating a closed-loop control system that adapts to changing laundry conditions
2Productivity
If the inner drum rotates at high speed, then the cleaning effect is improved through squeezing and washing, but water pipes may be disconnected causing water leakage or personal injury
Solution Approach 1:
The system performs preliminary stability assessment by detecting laundry load and calculating eccentricity before enabling high-speed operation. This preventive measure ensures that the washing device only operates at high speed when the laundry distribution is balanced, eliminating the risk of water pipe disconnection and water leakage before it can occur
3Device complexity
If eccentricity threshold is fixed, then the control logic is simple, but the washing device cannot adapt to different laundry loads effectively
Solution Approach 1:
The system uses dynamic threshold values for eccentricity detection that are adjusted based on the detected laundry load. Different load levels have different corresponding threshold values, allowing the system to adapt to varying laundry conditions while maintaining stable operation. This dynamic adjustment mechanism balances control simplicity with load adaptability
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 method effectively prevents vibration and shifting, allowing for reliable operation in high-speed mode, thereby improving washing efficiency and safety by ensuring the washing device operates smoothly and reliably.
Implementation Method 1
a laundry load in a washing device is acquired
Implementation Method 2
By rotating the inner drum at a high speed, the laundry tightly clings to a drum wall of the inner drum and rotates along with the drum
Implementation Method 3
laundry is lifted from the bottom of the inner drum by means of lifting ribs provided in the inner drum, and falls from a high place under the action of gravity to clean the laundry by tumbling the laundry onto the inner drum

AI summary
A washing control method, apparatus and device for a washing device, and a storage medium are disclosed. The method comprises: acquiring (101) a laundry load in a washing device; determining (102) an eccentricity threshold of the washing device based on the acquired load; controlling (103) the washing device to operate in a first washing mode, and acquiring an eccentricity of the washing device in the first washing mode; and determining (104), based on the eccentricity and the eccentricity threshold, whether the washing device is switched to a second washing mode. Embodiments of the present application can set corresponding eccentricity thresholds according to different loads of laundry in the washing device, and can effectively switch the washing device to a second washing mode under the premise of ensuring that the washing device operates in the second washing mode reliably and smoothly, thereby improving the washing efficiency.
