Dryer Duct Cover Sealing Layout for Airflow and Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dryers face issues with vibration and noise due to the deformation of the rear panel, which affects the alignment of the rotating shafts and reduces the reliability of the reducer, and lack a structured approach for air flow and water management.
Innovation Solution
The laundry treating apparatus includes a duct cover system with a duct sealing unit and a sealing mount part to prevent air leakage, and a water storage tank for condensed water, allowing for efficient air circulation and easy assembly, while the motor is positioned behind the drum to reduce vibration and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driving unit is fixed to the rear panel of the cabinet, then the drum can be rotated, but the rear panel deforms or vibrates causing misalignment of rotating shafts
Solution Approach 1:
The cabinet is divided into a rear panel and a separate support structure (cross members and reinforcing ribs). The driving unit is mounted on the support structure rather than directly on the rear panel, segmenting the load-bearing function from the enclosing function.
Solution Approach 2:
Cross members are added in the horizontal dimension to create a rigid support framework. The reinforcing ribs extend in the vertical dimension to prevent panel deformation. This multi-dimensional support structure distributes loads effectively.
2Weight of moving object
If the rear panel is made thin to reduce weight, then the cabinet is lighter, but the rear panel is easily deformed or vibrated by external force
Solution Approach 1:
Reinforcing ribs are pre-installed on the rear panel before the driving unit is mounted. This preliminary reinforcement ensures the panel can withstand future loads without deformation, preventing vibration and misalignment issues.
Solution Approach 2:
The support structure combines the thin rear panel with additional structural elements (cross members and reinforcing ribs) to create a composite system that maintains light weight while achieving the required strength and stiffness.
3Reliability
If the driving unit is disposed parallel to the rotating shaft, then the drum rotates stably, but the assembly process is complex
Solution Approach 1:
The support structure serves multiple functions: it mounts the driving unit, supports the drum load, reinforces the rear panel, and provides alignment references. This multi-functionality simplifies the overall assembly process by combining several structural requirements into one integrated component.
