Ventilation Outlet Automatic Closing to Reduce Dust Accumulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation-air conditioners have open ventilation outlets when not in use, leading to dust accumulation and potential failures in the ventilation component.
Innovation Solution
An automatic air-output device is integrated into the ventilation and air conditioning system, which can open or close the ventilation outlet based on the operating state of the ventilation component, ensuring the outlet is closed when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the ventilation outlet is kept open for long-term use, then the ventilation component can provide continuous air supply, but dust enters the interior through the ventilation outlet causing failures
Solution Approach 1:
The patent applies preliminary action by closing the ventilation outlet automatically when the ventilation component is not in use. The control system detects the operational state and proactively closes the outlet before dust accumulation can cause failures, while maintaining the ability to open it when needed for air supply.
2Object-affected harmful factors
If a baffle is used to close the ventilation outlet, then dust entry is prevented, but the outlet cannot be fully closed when the ventilation component is not working
Solution Approach 1:
The patent implements dynamics by using a movable closing mechanism (such as a door or shutter) controlled by an actuator that can transition between open and closed states. This dynamic structure allows the outlet to be fully closed when not in use, overcoming the limitation of fixed baffles that cannot provide complete sealing.
3Reliability
If the ventilation outlet is closed when not in use, then dust accumulation is reduced, but the structure becomes more complex with additional opening and closing mechanisms
Solution Approach 1:
The patent applies universality by integrating the opening and closing mechanism into the existing ventilation system architecture. The control system that manages ventilation operation also controls the outlet closing function, and the mechanism serves both as a seal and as part of the overall system housing structure, reducing the need for entirely separate components.

AI summary
The present disclosure provides a ventilation and air conditioning system. The ventilation and air conditioning system includes a ventilation system and a heat exchanging system. The ventilation system has a ventilation outlet provided with an automatic air-output device. With the automatic air-output device arranged at the ventilation outlet of the ventilation system, the automatic air-output device is associated with power on and power off of the ventilation system. When the ventilation system is powered on, the automatic air-output device is triggered therewith to open the ventilation outlet of the ventilation system, to allow fresh air of the ventilation system to flow indoors. When the ventilation system is powered off, the automatic air-output device is triggered therewith to close the ventilation outlet. As a result, the ventilation outlet can be in a closed state when the ventilation system is not in use, thereby reducing accumulation of dust in the ventilation system caused by that the ventilation system not being used, so as to reduce dust-related failures of the ventilation system and prolong the service life of the ventilation system.
