Indoor air conditioning unit and air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners have limited deflector angle range and difficulty in installation and cleaning, with the louver and deflector often installed and removed independently, making cleaning cumbersome.
Innovation Solution
An air conditioner indoor unit with a rotatable air deflector and modularized louver assembly, allowing for increased deflector rotation angles and easier installation and cleaning, featuring a housing with a volute assembly and air outlet duct, and a louver assembly connected to the air deflector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air deflector is provided at the air outlet to control the blowing direction, then the blowing direction can be controlled, but the angle range of swinging up and down is small (less than 90 degrees)
Solution Approach 1:
The air deflector is divided into multiple independent deflection plates that can be adjusted separately. Each deflection plate can be independently positioned to control airflow in different directions, enabling a wider overall angle range while maintaining precise directional control.
Solution Approach 2:
The air deflector transitions from a fixed structure to a dynamic adjustable structure. The deflection plates can be rotated and positioned at different angles, allowing the system to adapt to various blowing direction requirements and achieve an angle range exceeding 90 degrees.
2Adaptability or versatility
If the louver and air deflector are provided independently, then the blowing range can be increased, but the installation and removal become relatively difficult
Solution Approach 1:
The louver and air deflector are integrated into a single unified structure. The deflection plates are positioned within the louver assembly, combining the functions of both components. This integration simplifies installation and removal as a single unit while maintaining the extended blowing range provided by the louver's left-right swinging capability.
3Adaptability or versatility
If the louver and air deflector are provided independently, then the blowing range can be increased, but the cleaning becomes not easy for the users
Solution Approach 1:
By integrating the air deflector within the louver assembly, the cleaning process is simplified. Users can clean the integrated structure as a single unit, accessing all surfaces including the deflection plates through the same maintenance openings used for the louver, making cleaning easier while preserving the extended blowing range.

AI summary
An indoor air conditioning unit and an air conditioner. The indoor air conditioning unit comprises a housing (100), a volute component (200), an air deflector (300), and a louver component (400); the housing (100) is provided with an air outlet (110); and the volute component (200) is provided within the housing (100), and comprises an upper volute (210) and a lower volute (220), an air outlet duct (230) that communicates with the air outlet (110) being formed between the upper volute (210) and the lower volute (220). The air deflector (300) is rotatably mounted in the air outlet (110), so as to open or close the air outlet (110), and the middle part of at least one end of the air deflector (300) in the length direction is rotatingly connected to the housing (100) by means of a rotary shaft (350), such that the air deflector (300) has an upper open state in which same rotates around the rotary shaft (350) until a lower side of the air deflector (300) is near to the upper volute (210) and a lower open state in which an upper side of the air deflector (300) is near to the lower volute (220). The louver component (400) is connected to the windward surface (360) of the air deflector (300).
