Solution Overview
Problem
Laundry processing apparatuses with multiple washing parts face issues such as vibration interference and prolonged water supply times when operating simultaneously, leading to frequent errors in water supply and operation.
Innovation Solution
A laundry processing apparatus with a controller that sets a simultaneous operation mode, adjusts standard data for error determination, and monitors water supply and level changes to differentiate between single and multiple washing part operations, reducing errors by modifying parameters like water supply time, draining time, and heating temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple washing parts operate simultaneously, then washing capacity and productivity are improved, but water supply time increases and errors occur more frequently
Solution Approach 1:
The system dynamically adjusts operational parameters based on the number of simultaneously operating washing parts. The controller monitors operation states and automatically modifies water supply standards, error determination thresholds, and operational timing according to whether one or multiple washing parts are running, thereby optimizing water supply efficiency and reducing delays during multi-part simultaneous operation
Solution Approach 2:
The patent changes key operational parameters including water supply time thresholds, error determination standards, and operational timing based on the simultaneous operation mode. By adjusting these parameters dynamically according to the number of active washing parts, the system resolves the contradiction between maintaining high productivity during simultaneous operation and preventing water supply delays
2Productivity
If multiple washing parts operate simultaneously, then washing capacity is improved, but error frequency increases due to vibration interference and water supply conflicts
Solution Approach 1:
The system dynamically switches between single-operation mode and simultaneous-operation mode based on real-time detection of washing part operation states. In simultaneous operation mode, the controller adjusts error determination standards and operational parameters to account for vibration interference and water supply conflicts, thereby maintaining reliability while preserving high productivity
Solution Approach 2:
The controller continuously monitors the operation states of all washing parts and uses this feedback to determine whether simultaneous operation is occurring. Based on this feedback, the system automatically adjusts operational parameters and error thresholds, creating a closed-loop control system that maintains reliability during simultaneous high-capacity operation
3Device complexity
If standard error determination data is used during simultaneous operation, then system complexity is reduced, but error determination accuracy deteriorates
Solution Approach 1:
The system dynamically selects between standard error determination data and adjusted error determination data based on the simultaneous operation mode. This dynamic adaptation allows the system to maintain high error determination accuracy during simultaneous operation without significantly increasing control system complexity, as the switching logic is integrated into the existing controller
Solution Approach 2:
The patent changes error determination thresholds and operational standards based on whether simultaneous operation is detected. By adjusting these parameters according to the operation mode, the system achieves accurate error determination during simultaneous operation while maintaining relatively simple control logic through systematic parameter adaptation

AI summary
The present invention relates to a laundry processing apparatus and a control method therefor, and to a laundry processing apparatus having a plurality of washing parts for performing washing independently of each other, the apparatus: determining whether the plurality of washing parts simultaneously perform washing; and determining whether a simultaneous operation is performed on the basis of the time required when water is supplied, so as to determine an error for the simultaneous operation on the basis of a standard different from an error determination standard during a single operation, thereby reducing the errors frequently occurring because of the simultaneous operation in a normal state.
