Laundry treating apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry dryers face issues with vibration and noise due to the deformation of the rear panel when the driving unit is fixed to it, leading to misalignment of components and reduced reliability of the speed reducer, and they lack an effective structure for managing condensed water and air flow.
Innovation Solution
A laundry treating apparatus with a driving unit positioned separately from the base allows for a larger water collection area, preventing water accumulation and foreign substances, and includes a circulation flow path that directs air effectively, while the driving unit is directly connected to the drum for stable rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the driving unit is fixed to the rear panel of the cabinet, then the driving unit can be stably supported, but the rear panel deforms or vibrates under load causing misalignment of components
Solution Approach 1:
The support structure is divided into multiple independent support legs that contact the rear panel at discrete points rather than fixing the driving unit to the entire rear panel. This segmentation distributes the load and prevents panel deformation while maintaining support stability.
Solution Approach 2:
Support legs act as intermediary elements between the driving unit and the rear panel. These legs provide the necessary mechanical support while isolating the driving unit from the deformation and vibration caused by panel flexibility, thus maintaining component alignment.
2Ease of manufacture
If the driving unit is fixed to the rear panel, then installation is simplified, but vibration and noise increase due to panel deformation
Solution Approach 1:
The support structure uses multiple discrete support legs instead of a continuous mounting surface. This segmentation allows the driving unit to be supported at multiple points while preventing the transmission of vibration and noise through the rear panel.
Solution Approach 2:
The support legs serve as intermediary elements that decouple the driving unit from the rear panel. This intermediary structure provides stable support while preventing the panel deformation that causes vibration and noise.
3Productivity
If the driving unit is positioned close to the drum, then the connection is direct and efficient, but the base structure becomes crowded and difficult to design
Solution Approach 1:
The support legs extend vertically from the base to support the driving unit, utilizing the vertical dimension to accommodate the driving unit's position. This allows the driving unit to be positioned at an appropriate height for direct connection to the drum while maintaining a compact base structure.
Solution Approach 2:
The base structure is segmented into a main body and support legs, allowing the driving unit to be positioned at an optimal location for efficient drum rotation while keeping the base design manageable through modular construction.

AI summary
A laundry treating apparatus includes a cabinet, a drum for accommodating laundry, a base disposed below the drum, a motor for providing power to rotate the drum, and a heat exchange unit including a first heat exchanger, a second heat exchanger, and a compressor. The base includes a circulation flow path part through which air in the drum circulates, a compressor installation part spaced apart from the circulation flow path part and configured to allow the compressor to be seated thereon, and a water collection part spaced apart from the compressor installation part and communicating with the circulation flow path part to collect water condensed in the circulation flow path part. The area of the water collection part is formed to be larger than the area of a pump installed in the water collection part.
