Window air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window air conditioners suffer from high operating noise and poor sealing, making them inconvenient to install and inefficient in noise and temperature insulation.
Innovation Solution
A window air conditioner design featuring a casing with a receiving groove that divides it into indoor and outdoor parts, equipped with a sealing assembly and angle-positioning assembly for easy installation and effective sealing, allowing the window to extend into the groove and separate the indoor and outdoor assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the window air conditioner is sealed, then the sealing effect is improved, but the sealing device becomes bulky and inconvenient to seal
Solution Approach 1:
The sealing device is divided into multiple sealing components: a first sealing component (brush seal) for the gap between the indoor assembly and window, and a second sealing component (weather stripping seal) for the gap between the outdoor assembly and window. This segmentation allows each sealing component to be independently designed and installed, simplifying the overall sealing system while maintaining effective sealing performance.
Solution Approach 2:
The receiving groove structure allows the window to extend into the casing, creating nested layers of sealing. The first sealing component is arranged in the receiving groove, and the second sealing component is arranged on the outer peripheral wall, forming a multi-layer nested sealing system that improves sealing effectiveness without requiring a single bulky device.
2Device complexity
If the window air conditioner uses a conventional rectangular parallelepiped casing, then the structure is simple, but the noise on the outdoor side is easily transmitted to the indoor side
Solution Approach 1:
The casing is divided into an indoor assembly and an outdoor assembly by the receiving groove, creating separate acoustic zones. This segmentation prevents noise from the outdoor side (including fan noise and operating sounds) from directly transmitting to the indoor side, as the receiving groove and sealing components form an acoustic barrier between the two assemblies.
3Object-affected harmful factors
If the window air conditioner separates indoor and outdoor parts, then noise insulation is improved, but the installation complexity increases
Solution Approach 1:
The receiving groove serves multiple functions: it separates the indoor and outdoor assemblies for noise insulation, provides a mounting structure for the first sealing component, and guides the window extension. This multi-functionality reduces the need for additional separate components, simplifying installation despite the separated assembly structure.

AI summary
A window air conditioner includes a casing including a receiving groove formed at an outer peripheral wall of the casing. The receiving groove has an open top, an open left side, and an open right side. The casing is divided into an indoor part and an outdoor part by the receiving groove. The window air conditioner further includes an indoor heat exchanger and an indoor fan arranged in the indoor part, and an outdoor heat exchanger and an outdoor fan arranged in the outdoor part.
