Window Air Conditioner Bracket Layout for Motor Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window type air conditioners face issues with motor position deviation during transportation due to vibration, leading to abnormal noise and fan damage, which affects reliability and user experience.
Innovation Solution
The design incorporates an integrated bracket with a thermal insulation partition and a volute to stabilize the motor and fans, ensuring their positions remain stable during transportation and use, preventing interference and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the motor is mounted on the bottom plate of the shell, then the structure is simple and easy to manufacture, but the motor position deviates due to vibration during transportation, causing fan interference and abnormal noise
Solution Approach 1:
The bottom plate is segmented into a mounting plate and a support plate, which are separately positioned and connected through connecting columns. The motor is mounted on the mounting plate while the support plate provides additional stabilization, preventing motor position deviation during transportation without complicating the overall manufacturing process.
Solution Approach 2:
The mounting plate and support plate are nested within the shell structure, with the connecting columns integrating both plates into a unified stable base. This nested arrangement provides enhanced motor position stability while maintaining a compact and manufacturable design.
2Ease of operation
If the motor and fans are loosely mounted, then the assembly is easy to install, but the fans interfere with other parts causing abnormal noise or fan damage
Solution Approach 1:
The mounting plate and support plate are pre-positioned and connected through connecting columns before the motor and fans are installed. This preliminary structuring creates a stable framework that maintains proper fan positioning during operation, preventing interference with other parts while keeping the installation process straightforward.

AI summary
A window type air conditioner includes an indoor heat exchanger, an outdoor heat exchanger and a motor disposed in the shell. Rotating shafts at two ends of the motor are provided with an indoor fan and an outdoor fan. A thermal insulation partition is disposed on a bottom plate of the shell and divides the shell into an indoor side and an outdoor side. The thermal insulation partition includes a front clapboard fixed on the bottom plate of the shell and a thermal insulation volute disposed on the front clapboard. The indoor heat exchanger and the indoor fan are located in the thermal insulation volute. An integrated bracket is provided with a first mounting part for mounting and fixing the outdoor heat exchanger, a second mounting part for mounting and fixing the motor, and third mounting parts for connecting and fixing the front clapboard.
