Split-Base Indoor Unit for Easy Fan Wheel Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing indoor units for air conditioners require professional assistance for fan wheel maintenance and cleaning due to the complex dismounting process, which is inconvenient and costly, and can lead to heat exchanger damage during disassembly.
Innovation Solution
The indoor unit design allows for the fan to be detachably mounted to the lower base plate, enabling easy disassembly and maintenance without affecting the heat exchanger, facilitating the cleaning of the fan wheel and reducing the risk of heat exchanger damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fan wheel is mounted to the base plate together with the heat exchanger, then the structural integrity is improved, but the ease of maintenance deteriorates
Solution Approach 1:
The base plate is divided into an upper base plate and a lower base plate. The fan wheel is mounted to the lower base plate, which can be detached from the upper base plate. This segmentation allows the fan wheel to be maintained independently without affecting the heat exchanger mounted on the upper base plate, thus improving ease of maintenance while maintaining structural integrity through the modular design.
2Stability of the object's composition
If the fan wheel is limited by the heat exchanger and base plate together, then the structural stability is improved, but the ease of operation deteriorates
Solution Approach 1:
The base plate is segmented into upper and lower portions that can be detached from each other. The fan wheel is mounted on the lower base plate, which can be easily removed from the upper base plate. This provides structural stability during operation while enabling easy dismounting for maintenance, as the lower base plate can be separated without affecting the heat exchanger.
3Ease of operation
If the heat exchanger is dismounted to access the fan wheel, then the accessibility to fan wheel is improved, but the reliability deteriorates
Solution Approach 1:
The base plate is divided into detachable upper and lower sections. The fan wheel is mounted on the lower base plate, which can be removed independently from the upper base plate holding the heat exchanger. This provides direct access to the fan wheel without requiring dismounting of the heat exchanger, thus improving accessibility while maintaining the reliability and integrity of the heat exchanger.
