Detergent Dissolution Flow Path for Complete Washer Powder Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treating apparatuses face challenges in fully dissolving powdered detergent in wash water, leading to increased washing time and reduced performance due to incomplete dissolution, especially as the size of the apparatus increases.
Innovation Solution
Incorporating a detergent dissolution device that circulates wash water and detergent, using a pump and dissolution flow path to ensure complete dissolution before supplying it to the tub, along with a flow path switching valve to selectively open the detergent dissolution and supply paths, and a water level sensor to prevent backflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a detergent supply device is added to the laundry treating apparatus, then detergent supply capability is improved, but device complexity increases
Solution Approach 1:
The detergent supply device is integrated into the existing laundry treating apparatus structure, merging the detergent storage chamber with the tub assembly. The detergent dissolves in water within the storage chamber before being supplied to the tub, combining storage, dissolution, and supply functions in one integrated unit rather than separate components.
2Ease of operation
If powdered detergent is supplied directly to the tub, then ease of operation is improved, but dissolution completeness deteriorates
Solution Approach 1:
The system performs preliminary dissolution of powdered detergent in the detergent storage chamber before the washing cycle begins. Water is supplied to the storage chamber to dissolve the detergent in advance, ensuring complete dissolution before the detergent solution is transferred to the tub, thereby eliminating incomplete dissolution issues during the actual washing process.
Solution Approach 2:
The detergent storage chamber acts as an intermediary between the detergent supply and the tub. Instead of supplying powdered detergent directly to the tub, the system first dissolves it in water within the storage chamber, creating a detergent solution that is then supplied to the tub, ensuring complete dissolution through this intermediate step.
3Productivity
If the apparatus size is increased, then productivity is improved, but detergent dissolution effectiveness deteriorates
Solution Approach 1:
The detergent supply system is segmented into distinct functional zones: a detergent storage chamber for dissolution, a water supply path, and a transfer mechanism to the tub. This segmentation allows the dissolution process to occur in a dedicated small-volume chamber where complete mixing is achievable, independent of the overall large apparatus size, thereby maintaining dissolution effectiveness despite increased productivity capacity.
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
Ensures effective dissolution of powdered detergent, preventing clogging and improving washing performance by consistently supplying dissolved detergent to the tub, thus enhancing the overall washing process.
Implementation Method 1
a pump (53) and a dissolution flow path (573) to supply the wash water to the dissolution box (51) and to discharge the detergent and the wash water from the dissolution box (51)
Implementation Method 2
a water level sensor to prevent backflow

AI summary
A laundry treating apparatus is provided. The laundry treating apparatus may include a detergent storage device positioned below an introduction port for introducing laundry into and removing laundry from a washing tub of the apparatus, a detergent dissolution device to dissolve detergent in water, and a flow path switching valve to selectively open a flow path for dissolution of the detergent and a flow path for supply of the dissolved detergent and washing water solution to the washing tub.
