Air conditioner indoor unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air conditioner indoor units with double air deflectors face a structural limitation, resulting in a significant difference in lengths between the inner and outer air deflectors, which compromises the air guiding effect and aesthetic appearance, as well as comfort due to inadequate airflow distribution.
Innovation Solution
The design incorporates a housing with separate accommodating portions for the inner and outer air deflectors, allowing them to pivot independently, reducing the dimension difference and enhancing airflow by creating a Coanda effect, while also facilitating a shower-type blowing mode for improved user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the inner air deflector is directly fixed in the air outlet accommodating cavity of the base, then the structure is simple, but the dimension difference between inner and outer air deflectors is large and the air guiding effect is poor
Solution Approach 1:
The housing is divided into a main body and a separately provided accommodating portion for the inner air deflector. This segmentation allows the inner air deflector to be properly positioned and sized relative to the outer air deflector, reducing the dimension difference and improving the air guiding effect while maintaining structural simplicity through modular design.
Solution Approach 2:
The accommodating portion for the inner air deflector is integrated within the housing structure, creating a nested arrangement where the inner air deflector is housed in a dedicated cavity. This nesting approach allows precise positioning and sizing of the inner air deflector relative to the outer air deflector, improving air guiding effectiveness without significantly increasing overall structural complexity.
2Device complexity
If only a single layer of recess is provided for accommodating the outer air deflector, then the housing structure is simple, but the air guiding effect and aesthetic appearance are compromised
Solution Approach 1:
The housing structure is segmented into multiple functional layers: the main housing body and a separately provided accommodating portion for the inner air deflector. This segmentation enables optimized positioning of both inner and outer air deflectors, improving air guiding effect and aesthetic appearance while maintaining reasonable structural complexity through modular construction.
3Ease of manufacture
If the inner and outer air deflectors have large dimension difference, then the structure is easier to manufacture, but the aesthetic appearance and comfort are reduced
Solution Approach 1:
The nested arrangement of the inner air deflector within the dedicated accommodating portion allows for optimized dimensional proportions between the inner and outer air deflectors. This reduces the dimension difference, improving aesthetic appearance and comfort, while the modular nested structure remains easy to manufacture through standardized assembly processes.

AI summary
An air conditioner indoor unit (100), comprising: a housing (1), comprising a first accommodating portion (11) having a first accommodating space and a second accommodating portion (12) having a second accommodating space, the first accommodating portion (11) having an air outlet (111); an inner air deflector (2), rotatable between a first closed position where the inner air deflector (2) is accommodated in the first accommodating space and a first open position for opening the air outlet (111); and an outer air deflector (3), rotatable between a second closed position where the outer air deflector (3) is accommodated in the second accommodating space and a second open position for opening the second accommodating space. When the inner air deflector (2) is located at the first closed position and the outer air deflector (3) is located at the second closed position, the inner air deflector (2) is located behind the outer air deflector (3) and is shielded by the outer air deflector (3).
