Detergent Supplier Common Passage to Reduce Washer Residue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry treating apparatuses face challenges in long-term detergent storage and efficient detergent supply, often resulting in detergent remaining in small storage spaces and requiring multiple passages for different detergents.
Innovation Solution
A laundry treating apparatus with a detergent supplier featuring a storage body with separate compartments for different detergents, a water supply passage, and a liquid detergent supply part that uses a pump and valve system to alternately supply wash water and liquid detergent through a common passage, minimizing detergent residue and eliminating the need for separate passages for each type of detergent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate passages are used for different detergents, then each detergent can be supplied independently, but the device complexity increases and multiple passages are required
Solution Approach 1:
The patent implements a single common passage that can supply multiple different types of detergents (powder detergent, liquid detergent, and sheet detergent) to the tub. The passage body is designed with a universal interface that accommodates different detergent storage containers, allowing one passage to perform multiple detergent supply functions that would traditionally require separate passages for each detergent type.
2Device complexity
If a common passage is used for multiple detergents, then device complexity is reduced, but detergent residue may remain in the passage
Solution Approach 1:
The patent employs a circulation mechanism where wash water is continuously supplied through the common passage to the tub, and the same passage is used to return water to the detergent storage containers. This continuous circulation of water through the passage helps flush and dissolve any remaining detergent residue, preventing buildup and ensuring the passage remains clear for the next detergent supply cycle.
3Volume of stationary object
If small storage spaces are used for detergents, then the device size is reduced, but detergent cannot be completely discharged and residue remains
Solution Approach 1:
The patent introduces wash water as an intermediary medium that enters the detergent storage containers through the common passage. This wash water acts as a carrier that dissolves and transports remaining detergent from the storage containers, ensuring complete discharge of the detergent supply and minimizing residue in the storage spaces.
4Duration of action of stationary object
If detergent is stored for long term, then user convenience is improved, but detergent may degrade or become ineffective
Solution Approach 1:
The patent implements a preliminary water supply action where wash water is introduced into the detergent storage containers before the detergent is fully consumed. This preliminary action of adding water helps maintain the detergent in a usable state during storage, preventing degradation and ensuring the detergent remains effective throughout the storage period.
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
The apparatus effectively stores and supplies detergents for extended periods, reduces detergent residue, and allows for the use of a common passage for multiple detergents, enhancing operational efficiency and user convenience.
Implementation Method 1
a pump configured to discharge the second detergent in the second storage part from the second storage part
Implementation Method 2
a valve configured to selectively open and close the body perforating hole
Implementation Method 3
The ball may be configured to allow fluid flow from the body perforating hole into the cover perforating hole and to prevent the wash water from flowing from the cover perforating hole into the body perforating hole

AI summary
A laundry treating apparatus includes a cabinet, a laundry receiving part provided within the cabinet and configured to receive laundry, a water supply part configured to supply wash water, and a detergent supplier configured to supply detergent. The detergent supplier includes a storage body having a first storage part configured to hold a first detergent and a second storage part configured to hold a second detergent. The first storage part is configured to communicate with the laundry receiving part, and the second detergent is in liquid form. The detergent supplier further includes a passage body having a water supply passage that is configured to supply the first storage part with the wash water from the water supply part, and a liquid detergent supply part that is configured to supply the water supply passage with the second detergent from the second storage part.
