Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners face challenges in optimizing air flow direction and reducing flow resistance, leading to increased noise and inefficient temperature distribution due to the arrangement of air inlets and outlets on the same plane, which interferes with airflow paths.
Innovation Solution
The air conditioner indoor unit features a first air guide assembly that can move relative to the panel, adjusting the size and direction of the air outlet through a driving assembly, allowing for multiple blowing modes, including horizontal, vertical, and simulated natural wind patterns, thereby optimizing airflow and reducing resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If air inlets and outlets are arranged on the same plane, then the structure is simple, but airflow paths are interfered with and flow resistance increases
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional spatial arrangement. The air guide assembly extends outward from the panel to form a three-dimensional air outlet structure, allowing air inlets and outlets to be positioned in different spatial planes. This dimensional change enables airflow paths to pass through the air guide assembly without interference, reducing flow resistance while maintaining structural simplicity.
2Device complexity
If air inlets and outlets are arranged on the same plane, then the structure is simple, but noise increases due to inefficient airflow
Solution Approach 1:
By extending the air outlet structure in the third dimension (outward from the panel), the patent creates optimized airflow paths that reduce turbulence and resistance. This three-dimensional configuration allows for smoother airflow, reducing noise generation from turbulent flow while keeping the overall structure simple and integrated.
3Device complexity
If fixed air outlet structure is used, then the device is simple, but airflow direction cannot be adjusted for different blowing modes
Solution Approach 1:
The patent introduces a driving assembly that enables the air guide assembly to move dynamically between a retracted position (flush with the panel) and an extended position (protruding from the panel). This dynamic capability allows the air outlet structure to adjust its position and orientation, enabling multiple blowing modes (horizontal, vertical, and simulated natural wind) while maintaining a simple integrated design when not in use.

AI summary
An air conditioner indoor unit includes a housing, a panel, a fan assembly, a first air guide assembly, and a first driving assembly. The panel includes a first air outlet. The first air guide assembly is located on a side of the panel away from the housing, and a second air outlet is constituted between an edge of the first air guide assembly and an edge of the first air outlet. The first driving assembly is configured to drive the first air guide assembly to move relative to the panel, so as to change a size of the second air outlet to adjust a flow direction of air flowing out from the second air outlet. The first air guide assembly includes a flow direction changing structure, and the flow direction changing structure is configured to move in a direction different from a moving direction of the first air guide assembly.
