Air conditioner and control circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners lack precise control over airflow orientation and temperature distribution, leading to inefficient temperature regulation in rooms, with airflows often deviating and not being effectively managed to maintain a pleasant temperature environment.
Innovation Solution
An air conditioner system incorporating a structural body with a first wind direction plate, auxiliary housings, a second wind direction plate, and a control circuit that adjusts the posture of these components to ensure the temperature-adjusted airflow stays within a certain range, using blower fans and wind direction plates to control airflow direction and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If airflow is blown out from multiple air outlets without coordinated control, then air distribution coverage is improved, but airflow orientation control precision deteriorates
Solution Approach 1:
The air outlet system is segmented into a first air outlet for temperature-adjusted airflow and a second air outlet for indoor airflow, each with independent wind direction plates. This segmentation allows separate control of each airflow stream while maintaining overall coverage, resolving the contradiction between coverage area and control precision.
Solution Approach 2:
The wind direction plates are designed to be dynamically adjustable with interconnected control mechanisms. When the first wind direction plate changes posture, the second wind direction plate automatically adjusts to maintain a predetermined intersection angle, enabling real-time precision control of airflow orientation while covering multiple directions.
2Adaptability or versatility
If wind direction plates are adjusted independently for each air outlet, then airflow direction flexibility is improved, but temperature environment regulation efficiency deteriorates
Solution Approach 1:
The control circuit establishes a feedback mechanism where the posture of the first wind direction plate serves as input to automatically adjust the second wind direction plate. This feedback loop ensures that both airflows work cooperatively to regulate temperature efficiently, rather than operating independently and potentially counterproductively.
Solution Approach 2:
The second wind direction plate serves multiple functions: it controls the indoor airflow direction independently while also responding to the first wind direction plate's position to maintain optimal airflow intersection angles. This multi-functionality allows flexible adaptation to different operational conditions while maintaining temperature regulation efficiency.
3Area of stationary object
If temperature-adjusted airflow is allowed to spread freely without constraints, then air circulation coverage is improved, but temperature distribution control deteriorates
Solution Approach 1:
The second airflow from the second air outlet acts as an intermediary element that works in conjunction with the first temperature-adjusted airflow. By controlling the intersection angle between these two airflows, the system guides the temperature-adjusted airflow to stay within desired zones while expanding overall circulation coverage, achieving both broad coverage and precise temperature control.

AI summary
There is provided an air conditioner which can make a pleasant temperature environment. An air conditioner 12 includes a main body unit 25 and an auxiliary housing 26. The main body unit 25 forms a first air outlet 31 which blows out a cool or warm airflow. The auxiliary housing 26 is attached to at least one side of the first air outlet 31 to be freely movable, and forms a second air outlet 56 which blows out taken-in indoor air. A control circuit controls a second wind direction plate 57 so that a second reference plane PL2 which regulates a wind direction of the second wind direction plate 57 intersects a first reference plane PL1 which regulates a wind direction of a first wind direction plate 39, on a downstream side of the airflow.
