Dehumidifier Assembly with Central Compressor for Compact Footprint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dehumidifiers face challenges in reducing their footprint while maintaining performance, often requiring off-center compressor mounting that limits heat exchanger placement and increases height, necessitating a need for a compact design with a lower-profile motor and larger surface area heat exchanger.
Innovation Solution
The dehumidifier assembly features a centrally mounted compressor aligned with the housing center, coupled with a magnetic-tip driven motor and a heat exchanger spanning across multiple side walls, allowing for increased surface area and reduced overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the compressor is mounted off-center to accommodate a centrally mounted fan hub, then the fan can be centrally mounted with motor and control system, but the heat exchanger cannot be mounted on every sidewall and the device height increases
Solution Approach 1:
The patent inverts the conventional mounting arrangement by placing the compressor at the center of the housing instead of off-center. This allows the heat exchanger to be mounted on all four sidewalls without interference, maximizing heat exchange surface area while maintaining compact dimensions.
Solution Approach 2:
The patent uses asymmetric component layout where the fan hub is positioned adjacent to one sidewall rather than centrally, and the compressor is centrally mounted. This asymmetric arrangement optimizes space utilization and allows heat exchanger panels to be installed on all sidewalls without interference from other components.
2Device complexity
If the compressor is mounted off-center, then space can be allocated for fan hub components, but the footprint of the dehumidifier increases
Solution Approach 1:
The patent inverts the conventional layout by placing the compressor at the center rather than off-center. This central positioning allows for a more compact footprint as the heat exchanger can efficiently utilize all sidewalls, reducing the overall device dimensions while maintaining all necessary functional components.
3Device complexity
If the fan hub is centrally mounted, then motor and control system can be integrated, but the dehumidifier height must increase to accommodate off-center compressor
Solution Approach 1:
The patent inverts the vertical arrangement by placing the compressor centrally at the bottom of the housing rather than off-center. This allows the device to maintain a lower profile height while still accommodating all components including the fan hub, motor, and control system in an optimized vertical arrangement.
Solution Approach 2:
The patent optimizes the vertical dimension by arranging components in layers from bottom to top: compressor at the bottom center, heat exchanger panels on sidewalls, fan hub and motor above, and control system at the top. This dimensional optimization reduces overall height while maintaining all functional requirements.
