Laundry Machine Basement Airflow Layout for Quieter Condenser Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art laundry drying machines have inefficient cooling condenser designs that complicate the arrangement of operational devices, lead to increased power losses, and produce high noise due to complex air conduit paths, with cooling conduits typically located on the upper side of the machine, disrupting device placement and efficiency.
Innovation Solution
A laundry treating machine with a basement design featuring a lower side air path for efficient cooling, including a bottom wall with hollow spaces forming separate air conduits for inlet and outlet air flows, and a conveyor creating a Venturi effect to manage air flow and reduce noise, allowing for a more compact and rational device layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling conduits are placed on the upper side of the basement, then the condenser can be cooled, but the arrangement of operational devices becomes complicated and device layout is disrupted
Solution Approach 1:
The patent inverts the conventional location of cooling conduits from the upper side of the basement to the lower side. This inversion resolves the contradiction by providing unobstructed access to the upper basement area for operational devices while maintaining effective cooling of the condenser through the redirected air flow paths in the lower basement.
2Temperature
If air ports are connected to upper side conduits, then cooling air flow is achieved, but air ports must be placed at high positions or lower regions with complicated connections, reducing efficiency and increasing power losses
Solution Approach 1:
The patent inverts the conventional air port configuration by placing air ports at low positions on the front and rear walls and connecting them directly to the lower side cooling conduits. This eliminates the need for high position placement or complicated lower region connections, reducing air flow resistance and power losses while maintaining effective cooling.
3Temperature
If complex and tortuous air conduit paths are used, then cooling coverage is improved, but high noise is produced during operation
Solution Approach 1:
The patent inverts the conventional conduit path configuration by creating simple, direct air flow paths through the lower basement from front to rear walls. This inversion eliminates complex tortuous paths while maintaining comprehensive cooling coverage, thereby significantly reducing noise generation during operation.
4Temperature
If cooling conduits are placed on the upper basement side, then condenser cooling is achieved, but the machine footprint and device layout efficiency are reduced
Solution Approach 1:
The patent inverts the conduit placement from upper to lower basement side, which optimizes the use of machine footprint area. The lower side placement allows the upper basement space to be fully utilized for operational devices without obstruction, improving layout efficiency while maintaining effective cooling through the inverted air flow configuration.
