Washing Machine Detergent Container with Rotary Dissolving Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines require separate containers for solid and liquid detergents, and struggle to efficiently dissolve detergents in washing water, leading to incomplete washing and potential residue issues.
Innovation Solution
A washing machine with a detergent containing unit featuring a housing, a rotary device, and a nozzle device that mixes air with washing water to enhance detergent dissolution, allowing both solid and liquid detergents to be dissolved effectively within a single unit without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate containers are used for solid and liquid detergents, then detergent storage is organized, but device complexity increases and space is wasted
Solution Approach 1:
The patent combines separate solid detergent container and liquid detergent container into a single integrated detergent container. The container includes a solid detergent storage chamber and a liquid detergent storage chamber that share a common structure, allowing both types of detergent to be stored in one unit rather than requiring separate containers.
Solution Approach 2:
The detergent container is designed to serve multiple functions: storing both solid and liquid detergents, dispensing each type appropriately, and integrating with the washing machine's water supply system. This multi-functional design eliminates the need for separate specialized containers while maintaining organized storage.
2Productivity
If conventional detergent dissolving methods are used, then simple structure is maintained, but detergent dissolving efficiency is poor and residue remains
Solution Approach 1:
The patent introduces a vibration mechanism that vibrates the detergent container during the washing cycle. This vibration helps agitate the detergent,促进 dissolution, and prevents residue buildup by continuously moving the detergent particles and solution, thereby improving dissolving efficiency and reducing harmful residue.
Solution Approach 2:
The patent employs a water spray system that directs washing water onto the detergent in the container. This hydraulic approach ensures thorough wetting and dissolution of the detergent by forcing water through and over the detergent material, significantly improving dissolving efficiency compared to passive dissolution methods.
3Reliability
If additional rinse cycles are added to clean the detergent container, then residue is removed, but washing time increases
Solution Approach 1:
The patent implements a self-cleaning function that operates during the main washing cycle rather than requiring separate rinse cycles. The vibration mechanism and water spray system continue to operate after detergent dispensing, automatically cleaning residual detergent from the container walls and dispensing mechanisms, thus maintaining container cleanliness without extending the overall washing time.
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 solution enables efficient dissolution of both solid and liquid detergents in a single unit, reducing residue and eliminating the need for additional rinse cycles to clean the detergent container, thereby improving washing efficiency and convenience.
Implementation Method 1
a rotary device rotatably coupled with at least part of a path through which the detergent moves to dissolve the detergent in the washing water
Implementation Method 2
a nozzle device including a washing water inlet hole and at least one air inlet hole to mix the washing water with air and supply the washing water mixed with the air to the detergent container

AI summary
A washing machine including a body, a rotary tub disposed inside the body, and a detergent containing unit installed on the body to dissolve a detergent in washing water to supply the detergent. The detergent containing unit includes a housing coupled with the inside of the body, a detergent container contained in the housing to contain the detergent, and a rotary device rotatably coupled with at least part of a path through which the detergent moves to dissolve the detergent in the washing water. A dissolving ability of the detergent may be improved. Also, it is possible to dissolve a solid detergent and a liquid detergent in one detergent containing unit without an additional component. Also, since it is possible to prevent residual detergent from being left in the detergent containing unit after washing, it is unnecessary to additionally use a rinse function to clean the detergent containing unit.
