Multi-Tub Washing Machine with Centralized Detergent Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines with multiple tubs require manual distribution of detergent and softener between separate tubs, lacking an efficient mechanism for simultaneous supply to both tubs.
Innovation Solution
A washing machine design featuring a channel housing discharger system with separate detergent and softener channels, a discharging pipe, and a controller to selectively distribute detergent and softener to each tub, ensuring automatic and simultaneous supply during the washing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate housings are used for each washing tub, then each tub can be individually driven and washed simultaneously, but the structure for supplying detergent and softener becomes complex and requires manual intervention for at least one tub
Solution Approach 1:
The detergent supply system is segmented into separate channels for each washing tub. The detergent storage container is divided into multiple storage spaces, and the supply structure includes separate supply channels that can independently deliver detergent to the first washing tub or the second washing tub, allowing simultaneous operation without complex manual intervention.
Solution Approach 2:
A single detergent supply structure serves multiple functions by providing detergent to both washing tubs through a unified control mechanism. The controller can selectively activate different supply channels to deliver detergent to either tub or both tubs simultaneously, eliminating the need for separate manual supply systems while maintaining individualized control.
2Ease of operation
If detergent and softener are stored separately in containers, then they can be individually pumped and supplied according to processes, but the supply mechanism requires additional complexity to distribute to multiple tubs
Solution Approach 1:
The container is divided into multiple storage spaces for different detergent types, with separate supply channels for each space. This segmentation allows the system to automatically supply the correct detergent type to the correct tub without complex manual intervention, as each storage space and channel is dedicated to a specific function.
Solution Approach 2:
The supply structure acts as an intermediary between the storage container and the washing tubs. It includes control mechanisms that automatically select and activate the appropriate supply channel based on the washing process requirements, simplifying the overall operation while managing the complexity of distributing multiple detergent types to multiple tubs.
3Ease of manufacture
If the detergent supply structure is provided in only one housing, then the structure is simpler, but users must manually put detergent into the other washing tub
Solution Approach 1:
The detergent supply structure is segmented into multiple independent supply channels, each capable of delivering detergent to a specific washing tub. This allows the system to maintain a unified manufacturing approach while automatically distributing detergent to multiple tubs, eliminating the need for manual intervention.
Solution Approach 2:
The supply structure is designed to be dynamically controllable, with the ability to activate different supply channels based on real-time washing process requirements. The controller can selectively open or close supply channels to deliver detergent to the appropriate tub, making the system adaptable to different washing scenarios without manual intervention.
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
Enables convenient and automatic distribution of detergent and softener to both washing tubs, eliminating the need for manual intervention and enhancing user experience by integrating the supply mechanism within the machine's control system.
Implementation Method 1
a pump configured to generate air pressure to move the detergent or the softener through the channel

AI summary
The disclosure relates to the washing machine comprising: a plurality of washing tubs loaded with laundry and configured to do the laundry; a container configured to store detergent; a channel housing provided between the container and the plurality of washing tubs and formed with channels to supply the detergent from the container to the plurality of washing tubs; at least one pump configured to perform a pumping operation to move the detergent in the channel; and a controller configured to control the at least one pump to supply the detergent to one selected among the plurality of washing tubs. Thus, the washing machine supplies detergent from one container to the plurality of washing tubs, thereby improving convenience in use.
