Indoor Unit Sealing Structure to Prevent Drive Device Condensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning indoor units face safety concerns due to condensation on the driving device caused by air entering the gap between the driving device and the frame, leading to potential safety hazards.
Innovation Solution
An air-conditioning indoor unit design featuring a frame with an accommodating cavity, a chassis, and a sealing member that seals the accommodating slot adjacent to the outlet, preventing hot or cold air from entering and causing condensation on the driving device, ensuring normal operation and high safety performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the driving device is arranged on the chassis with a gap to the frame, then the structure is simple and easy to manufacture, but condensation occurs on the driving device due to air entering the gap
Solution Approach 1:
A sealing member is introduced as an intermediary component between the chassis and the frame to block the gap. The sealing member includes a sealing body with a sealing surface that abuts against the frame, and a limiting rib that prevents the sealing body from moving into the accommodating cavity. This intermediary element effectively blocks air flow into the gap while maintaining structural simplicity.
Solution Approach 2:
The sealing body is made of a flexible sealing material that can deform to fit the gap between the chassis and the frame. This flexible sealing member adapts to the dimensional variations and maintains effective sealing, preventing air from entering the gap and causing condensation on the driving device.
2Ease of repair
If the sealing member is made detachably connected, then the ease of repair is improved, but the sealing reliability may be reduced
Solution Approach 1:
The sealing member is designed with detachable connection capabilities, allowing it to be removed and reinstalled. The limiting rib structure provides dynamic positioning that guides the sealing body into the correct position during installation, ensuring reliable sealing while enabling easy removal for maintenance and repair operations.
3Manufacturing precision
If the sealing member is in interference fit with the slot wall, then the sealing precision is improved, but the device complexity increases
Solution Approach 1:
The sealing body utilizes the elastic deformation characteristics of sealing material to achieve interference fit with the slot wall of the frame. The flexible material naturally deforms to fill the gap and create a tight seal when installed, providing high sealing precision without requiring complex mechanical fastening structures or precision machining.
