Method for controlling laundry treating apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Installation defects, particularly balancing defects, in laundry treating apparatuses lead to excessive vibration and noise during operation, with many service requests resulting from improper balancing adjustments, especially in front-loading types.
Innovation Solution
A method for controlling a laundry treating apparatus that includes an installation inspection mode, where the system determines if an initial installation inspection command is input, performs checks on water supply, drainage, and balancing, and displays results to ensure proper installation and balancing according to stored unbalance values, prompting installers to follow installation guidelines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the installer adjusts the balance without putting the balance weight into the drum to complete the installation quickly, then the installation time is reduced, but the balancing defect occurs leading to excessive vibration and noise
Solution Approach 1:
The system performs preliminary detection of unbalance values during the installation phase by rotating the drum at maximum speed and measuring vibration. This allows the installer to complete the installation process without immediately adding balance weights, but ensures proper balancing is achieved before the appliance enters normal operation, thus resolving the contradiction between installation speed and balancing quality.
Solution Approach 2:
The control part stores the measured unbalance value in memory and provides feedback to the installer through the display part, indicating whether the balancing is adequate. This feedback mechanism guides the installer to make necessary adjustments while maintaining efficient installation workflow, preventing balancing defects without extending installation time significantly.
2Reliability
If the installer follows the installation guide to perform accurate balancing operation with balance weight, then the balancing quality is improved, but the installation time increases
Solution Approach 1:
The appliance performs self-detection of balancing status by automatically rotating the drum and measuring unbalance values without requiring the installer to manually assess balancing. This automation reduces the time needed for balancing operations while ensuring accurate detection, thus improving both balancing quality and installation efficiency.
Solution Approach 2:
The system replaces manual balancing assessment with automated sensor-based detection. Instead of relying on the installer's subjective evaluation or complex manual procedures, the control part uses vibration sensors and processing to objectively measure unbalance values, reducing installation time while maintaining high balancing quality.
3Measurement precision
If the system performs detailed installation inspection to detect balancing defects, then the detection precision is improved, but the device complexity increases
Solution Approach 1:
The control part serves multiple functions: it controls the drum rotation, processes vibration signals from existing sensors, stores unbalance values in memory, and displays inspection results. By making the control part multi-functional, the system achieves precise unbalance detection without adding separate dedicated hardware components, thus minimizing device complexity while maintaining high measurement precision.
Solution Approach 2:
The system detects balancing status by measuring vibration parameters during drum rotation at specific speeds. By utilizing existing vibration sensors and analyzing parameter changes during rotation, the system achieves accurate unbalance detection without requiring complex dedicated measurement equipment, resolving the contradiction between detection precision and system complexity.

AI summary
Provided is a method for controlling a laundry treating apparatus. The method includes applying power to the laundry treating apparatus and inputting an installation inspection command through an input part and performing an installation inspection for inspecting whether the laundry treating apparatus is normally installed when the installation inspection command is inputted. A control part determines whether the inputted installation inspection command is an initial installation inspection command, and wherein, when it is determined that the inputted installation inspection command is not the initial installation inspection command, the control part is configured to determine whether the previous installation and inspection has been properly performed according to an unbalance value stored in a memory, and configured to display the determined result a display part.
