Control method for air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners cause discomfort by directly blowing cold wind on the human body in cooling mode and fail to provide a comfortable heating effect in heating mode.
Innovation Solution
A control method for air conditioners that adjusts the opening degrees and directions of air guide plates and swing blades based on the actual working mode and indoor temperature difference, using motors to control the air flow direction and intensity, and incorporates a refrigerant circulation loop and sterilization devices to enhance user comfort and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the air outlet is arranged toward the bed position and wind blows directly on the human body, then heating effect is quickly felt in heating mode, but comfort is reduced and health may be affected in cooling mode
Solution Approach 1:
The air outlet is divided into upper and lower air outlets, allowing independent control of air flow directions. The guide plates and swing blades are segmented to separately adjust upper and lower air flows, enabling differentiated control to avoid direct cold wind on the body while maintaining heating effectiveness.
Solution Approach 2:
The patent employs dynamically adjustable guide plates and swing blades that can change their angles based on working mode (heating/cooling) and temperature differences. This dynamic adjustment allows the system to optimize air flow direction in real-time, directing air away from the body in cooling mode while maintaining effective heating in heating mode.
2Productivity
If the air guide plate opening degree is increased to enhance heating effect, then heating efficiency improves, but cold wind may blow directly on the human body when temperature difference is small
Solution Approach 1:
The control system continuously monitors the temperature difference between indoor environment and user requirements, and provides feedback to adjust the guide plate opening degrees accordingly. When temperature difference is large, opening degrees are increased for efficient heating; when temperature difference is small, opening degrees are reduced to prevent direct cold wind on the body.
Solution Approach 2:
The system changes the opening degree parameters of guide plates based on the magnitude of temperature difference. Different opening degree parameters are applied for different temperature difference conditions, optimizing both heating efficiency and comfort by preventing direct cold wind when temperature difference is small.
3Ease of operation
If multiple air outlets and guide components are added to control air direction, then user comfort is improved, but device complexity increases
Solution Approach 1:
The upper and lower guide plates and swing blades serve multiple functions: they control air flow direction, adjust opening degrees based on temperature difference, and prevent direct cold wind on the body. This multi-functionality allows the system to achieve comprehensive comfort control without adding excessive complex components.
Solution Approach 2:
The patent combines the functions of direction control and opening degree adjustment into an integrated system where guide plates and swing blades work together. The upper and lower air outlets are coordinated to provide complementary air flows, achieving enhanced comfort control through functional merging rather than adding separate independent systems.

AI summary
A control method for an air conditioner. An air conditioner comprises a housing (1) as well as an indoor heat exchanger (2) and a fan (3) which are arranged in the housing (1); an upper air outlet (14) and a lower air outlet (15) are formed on the front side of the housing (1); an upper deflector (4) and an upper flap (5) are arranged between the upper air outlet (14) and the fan (3); a lower deflector (6) and a lower flap (7) are arranged between the lower air outlet (15) and the fan (3). The control method for an air conditioner comprises: obtaining an actual indoor temperature (S1); comparing the actual indoor temperature with a temperature preset by a user (S2); determining whether an actual working mode of the air conditioner is a heating mode or a cooling mode (S3); and controlling the upper deflector (4), the upper flap (5), the lower deflector (6), and the lower flap (7) on the basis of the actual working mode and the comparison result (S4). The method can achieve the purposes of allowing people to quickly feel the heating effect of an air conditioner in an initial heating stage, and avoiding direct blowing of cold air on human bodies in an initial cooling stage.
