Indoor Blower Drive Layout for Stable Air Conditioner Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a drive module with a blower in air conditioner indoor units is not conducive to effective control and maintenance due to signal and power supply issues, leading to instability and inefficiency in operation.
Innovation Solution
The drive module is mounted separately within the electric control chamber, integrated with the main control module on a circuit board, and connected via a module pin with a foil and step structure, allowing for improved signal transmission and heat dissipation, while the radiator is positioned to enhance cooling and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the drive module is integrated into the blower, then the device complexity is reduced, but the control reliability and maintenance ease deteriorate due to signal and power supply issues
Solution Approach 1:
The patent divides the control system into separate modules: the main control module and the drive module are mounted separately on the circuit board rather than integrating the drive module into the blower assembly. This segmentation allows independent control and maintenance of each module, improving reliability while maintaining reasonable complexity.
Solution Approach 2:
The drive module is extracted from the blower integration and mounted separately on the circuit board within the electric control chamber. This extraction resolves the signal and power supply issues caused by close integration, enabling better control reliability and easier maintenance of the blower assembly.
2Device complexity
If the drive module is integrated into the blower, then the device complexity is reduced, but the ease of maintenance deteriorates
Solution Approach 1:
By segmenting the drive module as a separate component on the circuit board rather than integrating it into the blower, the patent enables independent maintenance of the drive module without disassembling the blower assembly, significantly improving ease of repair.
Solution Approach 2:
The drive module is extracted from the blower integration and mounted separately on the circuit board, allowing technicians to access and maintain the drive module independently from the blower assembly, thus improving maintenance convenience.
3Volume of moving object
If the drive module and main control module are closely integrated, then the space utilization is improved, but the heat dissipation effectiveness deteriorates
Solution Approach 1:
The patent applies local quality by providing dedicated heat dissipation structures (radiators) for high-heat components like the drive module and main control module, while allowing other areas to maintain compact integration. This enables effective heat dissipation at critical locations without compromising overall space utilization.
Solution Approach 2:
The patent utilizes three-dimensional space arrangement by mounting the drive module vertically or at angles relative to the main control module on the circuit board, and positioning radiators in different spatial dimensions. This allows heat dissipation in multiple directions while maintaining compact overall dimensions.
