Window air conditioner sealing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window air conditioners face issues with cold air leakage due to poor sealing between the unit and the window frame, affecting cooling and heating efficiency, and existing foldable louvers provide inadequate thermal insulation and sealing.
Innovation Solution
A window air conditioner design featuring a movable window sash with a receiving groove and a sealing device that rotates and extends to seal the gap between the sash and the window opening, utilizing thermal insulation materials and adjustable components for improved sealing and sound insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a foldable louver is used to seal the assembling gap, then the louver can be folded to save space, but the thickness of the louver is thin and thermal insulation effect is poor
Solution Approach 1:
The sealing device is divided into multiple segments that can fold relative to each other, allowing the sealing structure to be compact when not in use and extended when sealing is required. This segmentation enables the sealing device to adapt to different gap sizes while maintaining good thermal insulation performance through multiple layers of sealing material.
Solution Approach 2:
The sealing device adopts a nested structure where inner sealing components are placed within outer housing structures. When folded, the sealing elements nest within the housing to minimize space occupation. When deployed, they extend outward to provide effective sealing and thermal insulation across the assembling gap.
2Ease of operation
If a foldable louver is used to seal the assembling gap, then the louver can be folded, but the fit structure between the louver and the window air conditioner has a poor sealing effect
Solution Approach 1:
The sealing device incorporates flexible sealing films and elastic sealing elements that can deform to adapt to the irregularities of the assembling gap. These flexible components ensure reliable sealing contact between the window air conditioner and the window frame, preventing cold air leakage even when the gap dimensions vary.
Solution Approach 2:
The sealing device transitions from a static foldable louver to a dynamic sealing mechanism that can extend and retract. When the window air conditioner is installed, the sealing device dynamically extends to fill the assembling gap and create a tight seal. When not in use, it retracts to a compact position, maintaining both effectiveness and flexibility.
3Reliability
If the sealing device is extended to seal the gap, then sealing effectiveness is improved, but the device occupies more space
Solution Approach 1:
The sealing device employs a dynamic telescopic mechanism that allows it to extend only when sealing is required. During normal operation or when not installed, the sealing device remains in a retracted state, occupying minimal space. When installation or sealing is needed, it extends to provide effective sealing across the assembling gap, thus balancing sealing effectiveness with space efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances sealing effectiveness, reduces noise transmission, and improves cooling and heating efficiency by preventing cold air leakage and providing better thermal insulation.
Implementation Method 1
a sealing device (2) connected with the casing (1) and arranged corresponding to the receiving groove (111), the sealing device (2) having a sealed state, and in the sealed state, at least a part of the sealing device (2) is arranged outside the casing (1) and contacts with a lower end of the window sash (300) to seal a gap between the window sash (300) and the window opening (201)
Implementation Method 2
with the receiving groove (111) in the casing (1), the window sash (300) may be extended into the receiving groove (111) of the cabinet (11) when moving downwards, such that the window sash (300) may have a certain fixing to the mounting of the window air conditioner (100), and also have a certain sound insulation effect, thus reducing noises transmitted from the outdoor part to the indoor part

AI summary
A window air conditioner includes a casing including a cabinet. The cabinet includes a receiving groove formed at an outer peripheral wall of the cabinet. The receiving groove is recessed downwards to separate the cabinet into an indoor part and an outdoor part. 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 a compressor arranged in the outdoor part.
