Multi-Tub Washing Machine Cycle Synchronization Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines with a single tub face challenges in simultaneously cleaning laundry of different types and capacities, leading to inefficiencies such as separate washing operations, excessive time, and energy consumption, as they require multiple cycles for varying loads.
Innovation Solution
A washing machine with multiple tubs that allows for simultaneous or staggered stopping of operations based on predetermined times, using a controller to adjust operation end times and add functions like soaking or dehydration standby to synchronize completion times across tubs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single washing tub is used to clean all laundry, then the device complexity is reduced, but the productivity decreases due to multiple separate washing operations required for different types of clothing
Solution Approach 1:
The washing machine is divided into multiple independent washing tubs (first washing tub and second washing tub), each capable of operating separately to handle different types of laundry simultaneously. This segmentation allows parallel processing of different washing tasks, improving overall productivity without requiring a single complex tub to handle all variations.
2Adaptability or versatility
If multiple washing tubs are operated simultaneously with different washing conditions, then the adaptability increases for different clothing types, but the loss of time increases due to multiple machine visits required
Solution Approach 1:
The control unit continuously monitors the operation status and predicted completion times of both washing tubs. Based on this feedback, the system automatically adjusts operation end times by adding standby functions to ensure both tubs complete their cycles simultaneously, eliminating the need for users to check multiple tubs at different times.
3Loss of time
If washing tubs are controlled to stop simultaneously by adding standby functions, then the loss of time is reduced, but the use of energy increases due to extended operation periods
Solution Approach 1:
Instead of extending the operation of both tubs equally, the system applies standby functions only to the tub that would complete its cycle first. This partial action approach synchronizes completion times while minimizing additional energy consumption by avoiding unnecessary extension of the tub that already has a longer cycle time.

AI summary
A washing machine and a control method thereof are disclosed. The washing machine has a plurality of washing tubs to clean laundry in different ways classified according to capacity and types of clothing. Different washing tubs simultaneously stop operations or are stopped at different times spaced apart from each other by a predetermined time, although washing tubs have different washing conditions (e.g., different input times of laundry, different amounts of laundry, different washing courses, etc.) when laundry is cleaned using the washing tubs.
