Retractable Top Air Outlet Control for Draft-Free Air Conditioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners face challenges in adjusting air output volume and direction effectively, particularly when the compressor operates at high frequencies, leading to reduced air speed and direction control, which affects indoor temperature changes and user experience.
Innovation Solution
A control method for an air conditioner that includes a retractable top air output mechanism, adjustable air-out included angle, and air speed, allowing the top air output mechanism to stretch and adjust its angle and speed based on a wind shower instruction to optimize air distribution and reduce draft sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the compressor operates at high frequency to increase cooling capacity, then the cooling effect is improved, but the air speed and air output volume are reduced, affecting temperature distribution and user experience
Solution Approach 1:
The patent introduces a retractable top air output mechanism that can dynamically change its position between retracted and extended states. This dynamic adjustment allows the air conditioner to optimize air output characteristics: when extended, it provides additional air output path to maintain air speed and distribution even when compressor frequency is high, thereby resolving the contradiction between cooling capacity and air speed
Solution Approach 2:
The top air output mechanism adds a vertical dimension to air output, complementing the traditional horizontal side air output. By providing air output in another spatial dimension, the system can maintain effective air distribution and speed characteristics even when horizontal air output is limited by high compressor frequency operation
2Object-affected harmful factors
If the air output volume is reduced to decrease draft sensation, then user comfort is improved, but the indoor temperature change rate is affected
Solution Approach 1:
The patent divides the air output function into two separate mechanisms: side air output mechanism and top air output mechanism. This segmentation allows independent control of each mechanism's air output characteristics. The side mechanism can be controlled to reduce draft sensation by adjusting air output volume, while the top mechanism compensates to maintain adequate temperature change rate, thus resolving the contradiction
3Ease of operation
If the side air output mechanism is used to supply horizontal air, then air distribution is achieved, but direct cold air blow to users causes discomfort
Solution Approach 1:
The patent adds a vertical air output dimension through the top air output mechanism, which releases cold air from above. This allows the system to achieve air distribution without relying solely on horizontal air output that directly impacts users. The cold air from the top mechanism naturally descends, providing air distribution while avoiding direct horizontal cold air blow to users

AI summary
A control method for an air conditioner is provided. The air conditioner has a retractable top air output mechanism provided at a top thereof. The control method includes: controlling, in response to a specified wind shower instruction in a cooling mode, the top air output mechanism to stretch towards an outside of the air conditioner to open an air outlet of the top air output mechanism; adjusting, based on the specified wind shower instruction, an air-out included angle of the top air output mechanism to be within a first angle range; and adjusting, based on the specified wind shower instruction, a supply air speed of the top air output mechanism to be within a first air speed range.
