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
The laundry treating apparatus positions the driving unit separate from the base, allowing for a larger space for water collection and installation of components, with the water collection part and compressor installed parallel to each other, and the compressor located closer to the rear to reduce noise leakage, enabling efficient drying and water management.
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 securely mounted and rotate the drum, but the rear panel deforms or vibrates under the load and external forces, causing misalignment and noise
Solution Approach 1:
The patent extracts the driving unit from its conventional mounting position on the rear panel and relocates it to the base of the cabinet. This separation removes the driving unit's mounting load from the rear panel, preventing deformation and vibration. The base provides a stable mounting foundation that does not suffer from the same structural limitations as the thin rear panel.
Solution Approach 2:
The patent introduces a intermediate structure (the base) as a mediator between the driving unit and the cabinet. Instead of directly mounting the driving unit to the rear panel, the base serves as an intermediate platform that absorbs and distributes the mounting loads, protecting the rear panel from deformation while providing stable support for the driving unit.
2Device complexity
If the driving unit is fixed to the rear panel, then the structure is simplified, but the thin rear panel vibrates and deforms even under small external forces, generating noise and distortion
Solution Approach 1:
The patent extracts the driving unit from the rear panel mounting arrangement and relocates it to the base. This extraction removes the source of vibration and noise from the rear panel system, eliminating the harmful effects of panel deformation while maintaining a relatively simple overall structure.
3Productivity
If the driving unit is positioned close to the drum for direct connection, then the connection is efficient, but the rotating shaft becomes distorted when the rear panel deforms, damaging the speed reducer
Solution Approach 1:
The patent extracts the driving unit from the rear panel mounting position and relocates it to the base. This relocation maintains efficient power transmission through direct connection to the drum while protecting the rotating shaft and speed reducer from distortion caused by rear panel deformation. The base provides a stable reference frame that prevents misalignment.
4Volume of stationary object
If the compressor is positioned at the front of the base, then space is maximized, but noise leaks to the outside more readily
Solution Approach 1:
The patent applies asymmetric positioning of the compressor within the base, placing it closer to the rear rather than symmetrically or at the front. This asymmetric arrangement prioritizes noise reduction over maximum space utilization, accepting a slight reduction in space efficiency to achieve the beneficial effect of reduced noise leakage to the exterior.
