Washing Machine Rinse Water Optimization Using Bound Liquor Only
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current washing machine methods require rinsing with both bound and free liquor, consuming more energy and water, and taking longer to exchange the liquor, which can be inefficient.
Innovation Solution
A method for operating a washing machine that determines the optimal amount of rinsing water based on laundry load and drainage behavior, allowing only bound liquor to be used for rinsing, reducing energy and water consumption by eliminating the need for free liquor and speeding up the exchange process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rinsing is performed using both bound liquor and free liquor, then washing performance is maintained, but energy consumption increases and rinsing time is extended
Solution Approach 1:
The invention extracts and eliminates the free liquor rinsing step from the traditional two-liquor rinsing process. By determining the optimal amount of bound liquor based on load quantity, residual liquor, and drainage behavior, the system achieves effective rinsing using only bound liquor, thereby removing the energy-consuming free liquor circulation step while maintaining washing performance
Solution Approach 2:
The invention changes the parameter of rinsing liquor quantity and type by dynamically determining the optimal bound liquor amount based on load characteristics, residual liquor levels, and drainage behavior. This parameter optimization allows the system to achieve effective rinsing with reduced liquor volume and without requiring free liquor, thus reducing energy consumption while maintaining rinsing effectiveness
2Reliability
If rinsing is performed using both bound liquor and free liquor, then washing performance is maintained, but rinsing time is extended
Solution Approach 1:
The invention extracts and eliminates the free liquor rinsing step from the traditional two-liquor rinsing process. By determining the optimal amount of bound liquor based on load quantity, residual liquor, and drainage behavior, the system achieves effective rinsing using only bound liquor, thereby removing the time-consuming free liquor circulation step while maintaining washing performance
Solution Approach 2:
The invention performs preliminary determination of the optimal bound liquor amount before the rinsing process begins, based on load quantity, residual liquor, and drainage behavior. This preliminary calculation ensures that sufficient bound liquor is used from the start, eliminating the need for subsequent free liquor addition and extending rinsing efficiency without compromising washing performance
3Reliability
If a large amount of rinsing water is used to ensure complete rinsing, then washing performance is improved, but water consumption increases
Solution Approach 1:
The invention changes the parameter of rinsing water quantity by dynamically determining the optimal bound liquor amount based on load characteristics, residual liquor levels, and drainage behavior. This optimized parameter setting achieves effective rinsing with minimal water consumption, eliminating the waste associated with using excessive rinsing water while maintaining washing performance
Solution Approach 2:
The invention uses feedback from sensors that detect load quantity, residual liquor, and drainage behavior to dynamically adjust the bound liquor amount. This closed-loop control ensures that the optimal amount of water is used for each rinsing cycle, preventing both water deficiency and water excess, thereby maintaining washing performance while minimizing water consumption

AI summary
The invention relates to a method for operating a washing machine (100) with a drum (110). The method comprises a determination step, an execution step, and a reduction step. In the determination step, the required amount of rinse water for a rinse cycle of the washing machine (100) is determined. This amount of rinse water is determined using the load of laundry (115) in the drum (110), the residual liquor in the laundry (115) at the beginning of the rinse cycle, and the drainage behavior of the laundry (115). In the execution step, the rinse cycle is carried out using the determined amount of rinse water. The rinse water is completely absorbed by the laundry (115). During the rinse cycle, the drum (110) rotates. In the reduction step, the amount of liquor absorbed by the laundry (115) is reduced by the residual liquor and the rinse water.
