Indoor Air Conditioner Outlet Structure With Circular Louvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing structure of indoor air conditioner units with separate blowing fans and heat exchangers results in inefficient space utilization, energy consumption, and increased noise due to air resistance, and the air outlet or inlet ports are complex and difficult to control.
Innovation Solution
The indoor unit features a mixed flow fan with a heat exchanger located rearward, an inlet port for air suction, and a circular outlet port that can be adjusted by circular louvers driven by a louver drive motor, allowing for improved air discharge and control of air volume and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the blowing fan and heat exchanger are arranged at upper and lower portions respectively, then the air passage structure is simple, but the space utilization is inefficient and the air passage length increases
Solution Approach 1:
The patent merges the blowing fan and heat exchanger into a closely integrated configuration, where the blowing fan is positioned adjacent to the heat exchanger rather than at opposite ends. This combining approach reduces the overall air passage length and improves space utilization while maintaining the functional separation needed for air intake and heat exchange operations.
2Device complexity
If the blowing fan and heat exchanger are arranged at upper and lower portions, then the structural layout is straightforward, but the blowing fan experiences large load and energy efficiency decreases
Solution Approach 1:
By positioning the blowing fan closely adjacent to the heat exchanger, the patent reduces the distance air must travel through the passage. This shorter air path decreases the workload on the blowing fan, reducing its energy consumption and improving overall system efficiency while maintaining a straightforward structural layout.
3Volume of moving object
If the blowing fan and heat exchanger are arranged closely, then the air conditioner becomes compact and slim, but the blowing fan performance deteriorates and noise increases due to increased air resistance
Solution Approach 1:
The patent optimizes the local configuration around the blowing fan and heat exchanger interface, designing the air passage geometry and component positioning to minimize turbulence and resistance in the critical region where air flows from the heat exchanger to the fan. This localized optimization allows compact arrangement without sacrificing fan performance or increasing noise.
4Ease of operation
If horizontal or vertical blades are used to control the outlet port, then the discharge amount can be regulated, but the number of components increases and the structure becomes complicated
Solution Approach 1:
The patent extracts the discharge regulation function from the traditional blade mechanism and integrates it directly into the outlet port structure itself. The outlet port is designed with movable or adjustable elements that are part of the port structure rather than separate blade components, reducing the total number of parts while maintaining the ability to regulate discharge amount and direction.
5Ease of operation
If separate blades controlled by separate power sources are used, then the outlet port can be controlled, but the structure becomes complicated and design unity is lost
Solution Approach 1:
The patent merges the control mechanism for the outlet port into a unified structure where the port's opening and closing elements are integrated with the housing or frame. This allows the outlet port to be controlled as a single coordinated unit rather than through multiple independent blades, simplifying the overall structure and enabling more flexible design options while maintaining operational control.

Function Achieved in This Case
This configuration enhances operation efficiency, reduces noise, and achieves a compact size while simplifying the control of air discharge, allowing for independent regulation of the outlet port's opening and closing.

AI summary
An indoor unit of an air conditioner has an improved discharge structure of air. The indoor unit of an air conditioner includes a panel which defines an external appearance thereof and has an opening, a mixed flow fan which is located within the panel, a heat exchanger unit which is located rearward of the mixed flow fan, an inlet port which is located rearward of the heat exchanger unit so that air is suctioned from rearward of the heat exchanger unit to be introduced into the mixed flow fan, an outlet port which is exposed forward of the panel through the opening so that the air passing though the mixed flow fan is discharged through a front portion of the panel, and a plurality of circular louvers to open and close the outlet port by moving outwards from a center of the outlet port.
