Dual-Device Laundry Treatment Control for Overcurrent Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional front-loading laundry treatment apparatuses with auxiliary units face interruptions due to overcurrent when operated simultaneously, as they lack effective current management between the primary and secondary treatment devices.
Innovation Solution
A control method that dynamically adjusts the operation of multiple laundry treatment devices by monitoring and managing the current usage, allowing the apparatus to switch between different cycles to prevent overcurrent interruptions, ensuring simultaneous operation without power disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the laundry treatment apparatus and auxiliary laundry treatment apparatus are simultaneously operated, then the laundry treatment capacity is improved, but the operation of both devices may be interrupted due to overcurrent
Solution Approach 1:
The control device continuously monitors the current consumption of both the laundry treatment apparatus and auxiliary laundry treatment apparatus, and dynamically adjusts the operation of the auxiliary device based on real-time current feedback to prevent overcurrent interruptions while maintaining simultaneous operation capability
Solution Approach 2:
The operation mode of the auxiliary laundry treatment apparatus is dynamically changed based on current conditions: it operates normally when current is sufficient, switches to a reduced-load mode when current approaches limits, and suspends operation when overcurrent is detected, allowing flexible adaptation to power availability
2Productivity
If the auxiliary laundry treatment apparatus operates at full load, then the laundry treatment efficiency is improved, but the current consumption increases causing potential overcurrent interruptions
Solution Approach 1:
The control device changes operational parameters of the auxiliary laundry treatment apparatus based on current availability: it adjusts the load capacity and operation mode (normal operation, reduced-load operation, or suspension) to optimize the balance between treatment efficiency and current consumption

AI summary
A control method of a laundry treatment apparatus is disclosed. The control method includes supplying electric power to a first load unit to execute a first cycle set in a first treatment device (a first step), supplying electric power to a second load unit to execute a second cycle set in a second treatment device (a second step), when an amount of current per unit time that is supplied to the laundry treatment apparatus is equal to or greater than a predetermined reference current amount, terminating the second step and executing a third cycle set in the second treatment device so as to consume a lower amount of current than an amount of current per unit time necessary to execute the second cycle (a third step), terminating the first cycle of the first treatment device (a fourth step), and executing the second cycle of the second treatment device after completing the fourth step (a fifth step).
