Laundry treating apparatus and method for controlling the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dryers face issues with driving unit instability due to deformation of the rear panel, misalignment of rotating shafts, limited control over drum rotation, inefficient air circulation, and inconvenient water supply positioning, leading to reduced drying efficiency and user inconvenience.
Innovation Solution
The laundry treating apparatus features a direct drive system with a reducer to stabilize rotor rotation, secures space between evaporator and condenser for efficient air flow, positions the steam generator on the base for improved space utilization, and optimizes water supply for convenient steam generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the steam generator is disposed right on the base, then the structure is compact, but the base cannot effectively circulate air or condense moisture
Solution Approach 1:
The base is segmented into two functional regions: a circulation flow path part for air circulation and moisture condensation, and a steam generator installation part for housing the steam generator. This segmentation allows the base to fulfill both compact structure and effective air circulation functions simultaneously.
2Length of moving object
If the motor is disposed close to the base, then the connection is short, but the motor interferes with air circulation under the drum
Solution Approach 1:
The motor is repositioned from a location directly under the drum to a position behind the drum, utilizing the vertical and depth dimensions of the washing machine cabinet. This spatial reconfiguration allows the motor connection to remain efficient while clearing the air circulation path underneath the drum.
3Productivity
If the base is designed for air circulation, then moisture condensation is improved, but there is no dedicated space for the steam generator
Solution Approach 1:
The base is divided into distinct functional zones: the circulation flow path part handles air circulation and moisture condensation, while the steam generator installation part provides a dedicated mounting space. This zonal segmentation resolves the conflict between condensation efficiency and steam generator installation requirements.
4Volume of moving object
If components are densely packed, then the apparatus is compact, but maintenance and repair become difficult
Solution Approach 1:
The motor is extracted from its conventional position directly under the drum and relocated to the rear of the drum. This extraction creates accessible space for maintenance while maintaining compact overall dimensions, as the motor can be serviced from the rear without disassembling the entire drum assembly.
