Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioner indoor units have small air output volume and low cooling and heating efficiency due to structural limitations.
Innovation Solution
The air conditioner indoor unit features multi-angle air output through a first air outlet at the front and a second air outlet on the sides, with a movable breezeless member that can close or open these outlets to control airflow direction, and includes an air dispersing module with guide vanes and adjustable inner air guide plates to optimize airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional single air outlet structure is used, then the device complexity is low, but the air output volume is small and the cooling and heating efficiency is low
Solution Approach 1:
The air outlet is divided into multiple independent outlets (first air outlet at front, second air outlet at side) with different orientations. Each outlet can be independently controlled by the breezeless member to discharge air in different directions, thereby increasing the total air output volume and coverage area without requiring complex additional components
Solution Approach 2:
The breezeless member is designed to be movable between different positions (first position opening the first air outlet, second position closing it). This dynamic adjustment capability allows the system to optimize airflow distribution and adapt to different operational modes, increasing productivity while maintaining manageable structural complexity
2Productivity
If a conventional single air outlet structure is used, then the device complexity is low, but the cooling and heating efficiency is low
Solution Approach 1:
The air outlet system transitions from a single-direction outlet to multi-directional outlets by adding spatial dimensions. The first air outlet discharges air forward while the second air outlet discharges air to the side, creating three-dimensional airflow coverage that enhances cooling and heating efficiency throughout the room
3Object-affected harmful factors
If the breezeless member is positioned to close the first air outlet, then direct airflow on the body is reduced improving user comfort, but the air output volume may be restricted
Solution Approach 1:
When the breezeless member closes the first air outlet to eliminate direct airflow, the system extracts and redirects airflow through the second air outlet. This separation of functions allows the system to maintain air output volume while eliminating the harmful direct airflow effect, as the side-discharged air naturally provides gentler circulation

AI summary
An air conditioner indoor unit and an air conditioner are provided. The indoor unit has a surface frame, a breezeless member, a heat exchanger and a fan. A first air outlet is formed in a front lower part of the surface frame. At least one second air outlet is formed on at least one of a left side of the surface frame and a right side of the surface frame. The breezeless member is disposed on a front side of the surface frame and movable between a first position and a second position. When the breezeless member is located at the first position, the first panel opens the first air outlet. When the breezeless member is located at the second position, the first panel closes the first air outlet.
