Solution Overview
Problem
Existing washing machines face issues with dirt accumulation between the inner and outer drums, leading to secondary contamination of laundry due to the lack of effective and timely cleaning, and the need for a separate drum cleaning program complicates the control system and results in inconsistent cleaning effectiveness.
Innovation Solution
A control method and device that rinses the outer surface of the inner drum and inner surface of the outer drum during every washing process by controlling the water level and rotation of the inner drum to agitate the water flow between the drums, eliminating the need for a fixed-cycle cleaning program.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate drum cleaning program is set at fixed intervals, then the cleaning operation can be performed, but dirt accumulation still occurs leading to poor cleaning results
Solution Approach 1:
The patent merges the drum cleaning function with the regular washing process by integrating the cleaning water level control and inner drum rotation operations into existing washing and rinsing stages. This eliminates the need for a separate drum cleaning program while achieving continuous cleaning效果 during each washing cycle.
Solution Approach 2:
The patent implements continuous cleaning action during every washing process by controlling the water level to the cleaning water level and rotating the inner drum during rinsing stages. This ensures that the cleaning action is performed continuously rather than at fixed intervals, preventing dirt accumulation between cleaning cycles.
2Object-affected harmful factors
If a separate drum cleaning program is used, then cleaning can be performed, but it operates at fixed intervals allowing dirt accumulation
Solution Approach 1:
The patent ensures continuous cleaning action during every washing process by controlling the water level to the cleaning water level and rotating the inner drum during rinsing stages. This eliminates idle periods between cleaning operations, preventing dirt accumulation while maintaining washing efficiency.
Solution Approach 2:
The system uses the existing washing process resources (water circulation, inner drum rotation) to simultaneously achieve both laundry washing and drum cleaning functions. The cleaning action is performed using the same operational components during the washing process itself, eliminating the need for separate cleaning operations.
3Reliability
If drum cleaning is integrated into the regular washing process, then cleaning effectiveness is improved, but additional control operations are required
Solution Approach 1:
The patent makes the existing water level control and inner drum rotation systems multi-functional by enabling them to perform both laundry washing and drum cleaning functions. The same control operations that wash laundry also clean the drum, eliminating the need for additional dedicated cleaning control mechanisms.
Solution Approach 2:
The system achieves self-service by using its own operational resources (water circulation system, inner drum rotation mechanism) to perform the cleaning function. The washing machine cleans itself during the regular washing process without requiring external intervention or additional complex control systems.
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 approach reduces dirt accumulation, enhances cleaning effectiveness, simplifies the washing machine program design, and minimizes impact on the laundry by integrating drum cleaning into the regular washing process.
Implementation Method 1
controlling the inner drum to rotate so as to drive a water flow to agitate between the inner drum and the outer drum to wash an outer surface of the inner drum and an inner surface of the outer drum

AI summary
A washing machine and a control method and control device therefor, and a storage medium. The control method comprises: in a rinsing stage or after the rinsing stage is completed, controlling the water level in an outer tub to reach a cleaning water level; and controlling an inner drum to rotate so as to drive a water flow to agitate between the inner drum and the outer tub to wash the outer surface of the inner drum and the inner surface of the outer tub. Therefore, the deposition of dirt is reduced, and the cleaning effect is improved; additionally, program design is simplified, and the influence on washed clothes is reduced.
