Indoor air-conditioner unit with air deflector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor air-conditioner units have gaps between the air deflector and the air outlet when closed, affecting appearance and allowing dust and contaminants to enter, and lack multi-angle air supply capabilities.
Innovation Solution
An indoor air-conditioner unit with a retractable central supporting mechanism and an open-close mechanism for the air deflector, using foldable connecting rods and motor-driven ejecting devices to ensure a complete seal and allow for multi-angle air flow direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air deflector is designed to rotate around a fixed shaft, then the structure is simple, but gaps remain between the air deflector and air outlet when closed, affecting appearance and allowing contaminants to enter
Solution Approach 1:
The air deflector transitions from a fixed-rotation design to a dynamically adjustable design where the rotation axis can move. The ejecting mechanism allows the air deflector to change its position dynamically, enabling complete sealing when closed while maintaining rotation capability when open, thus resolving the contradiction between structural simplicity and sealing performance.
2Device complexity
If the air deflector rotates around a fixed shaft, then the mechanism is simple, but multi-angle air supply cannot be achieved
Solution Approach 1:
The system enables multi-angle air supply by allowing the air deflector to rotate and adjust its position dynamically. The ejecting mechanism provides the dynamic capability for the air deflector to achieve various angles, transforming a simple fixed-rotation mechanism into a versatile multi-directional air supply system.
3Ease of operation
If gaps are left between the air deflector and air outlet for rotation, then the air deflector can rotate freely, but dust and contaminants can enter the air-conditioner
Solution Approach 1:
The solution dynamically adjusts the position of the air deflector based on operational state. When rotation is needed, the ejecting mechanism positions the air deflector to allow free rotation. When closed, it achieves complete sealing to prevent contaminant entry, thus resolving the contradiction between rotation freedom and contaminant prevention.
Solution Approach 2:
The invention extracts the rotation function from the closed position, allowing the air deflector to rotate only when in the open position. The ejecting mechanism separates the rotation capability from the sealing requirement, enabling the air deflector to rotate freely when open while maintaining complete sealing when closed, thus preventing contaminant entry.

AI summary
An indoor air-conditioner unit comprises an air duct, an air outlet connected with the air duct, and an air deflector guiding directions of air flow from the air-conditioner. A volute tongue is provided in the air duct and near an outer end of the air outlet. Wherein, the indoor air-conditioner unit further comprises a central support mechanism, which is elastically arranged between the central part of the back of the air deflector and the volute tongue, thus a complete seal of the air outlet can be achieved when the air deflector is closed, i.e., there are no gaps in the air outlet.
