Indoor Unit Dual Air Outlet Structure for Uniform Room Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioners often create uneven indoor temperature environments due to a single air outlet direction, leading to discomfort, especially in heating mode where the bottom temperature is lower, making it feel cold at the feet.
Innovation Solution
An air conditioner indoor unit with a housing featuring a first and second air outlet, where the second air outlet is positioned below the first, and an adjustable air output channel system that includes a first air regulation channel area, which can be opened or closed to direct air flow based on the operation mode, enhancing temperature uniformity and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If air conditioner uses a single air outlet direction, then the device structure is simple, but the indoor temperature uniformity deteriorates
Solution Approach 1:
The air outlet is divided into two separate outlets: a first air outlet positioned above the heat exchanger assembly and a second air outlet positioned below the heat exchanger assembly. This segmentation allows air to be discharged from multiple locations, improving temperature uniformity throughout the indoor space while maintaining a relatively simple overall device structure.
Solution Approach 2:
The air outlet configuration transitions from a single-point discharge to a distributed multi-dimensional discharge pattern. By positioning air outlets at different vertical levels (above and below the heat exchanger) and configuring them with different orientations, the system achieves three-dimensional air distribution, significantly improving indoor temperature uniformity.
2Device complexity
If air conditioner discharges air through a single outlet, then the device structure is simple, but the comfort level deteriorates due to cold feet sensation in heating mode
Solution Approach 1:
The air outlet system is segmented into upper and lower outlets with different functions. The second air outlet (below the heat exchanger) is specifically configured to discharge air downward, creating a downward air flow that prevents cold air accumulation at the floor level, thereby eliminating the cold feet sensation and improving user comfort.
Solution Approach 2:
Different regions of the air outlet system are assigned different functional qualities. The second air outlet is specifically designed with a downward-discharging structure to address the local comfort issue at floor level, while the first air outlet handles overall temperature regulation. This localized functional differentiation improves comfort without requiring complete system redesign.
3Device complexity
If air conditioner uses fixed air outlet configuration, then the device structure is simple, but the adaptability to different operation modes deteriorates
Solution Approach 1:
The air outlet system incorporates dynamic regulation capabilities through adjustable components. The air outlet can change its discharge characteristics based on operation mode (cooling or heating), allowing the system to adapt to different thermal requirements. This dynamic behavior enables the air conditioner to optimize performance for each mode without requiring completely separate systems.
Solution Approach 2:
The air outlet system is designed with multi-functionality to handle both cooling and heating modes effectively. By configuring both first and second air outlets with appropriate orientations and regulation mechanisms, the system can discharge air in different directions depending on the mode, making it universally applicable to various operation conditions without needing mode-specific hardware.

AI summary
An air conditioner indoor unit includes a housing having an air inlet, a first air outlet, and a second air outlet arranged below the first air outlet, and an air output door assembly arranged at the second air outlet and connected to the housing. At least a portion of the air output door assembly is configured to move relative to the housing to form an air output channel between the at least a portion of the air output door assembly and the housing. The air output channel has a ring-shaped air output end located in front of the second air outlet. The air conditioner indoor unit further includes an opening-closing mechanism movably mounted at the air output door assembly and configured to open or close an air regulation channel area that includes an upper part of the air output channel.
