Wind Guide Panel Position Sensing to Cut Air Conditioner Startup Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioners require an initial operation to bring the panel into an initial state, which is unnecessary when the panel is already in that state, leading to wasted time and potential issues with normal operation, especially when power is cut off or the panel is forcibly opened.
Innovation Solution
A control apparatus and position detecting sensor system that determines the panel's state and only performs an initial operation when necessary, allowing the panel to be opened and closed efficiently by locking and releasing shafts based on the detected position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an initial operation is always performed to bring the panel into an initial state, then the panel can be reliably opened in the correct direction, but time is wasted when the panel is already in the initial state
Solution Approach 1:
The system performs preliminary detection of the panel's current state using a position detecting sensor before initiating the opening operation. Based on this detection, the control apparatus determines whether an initial operation is necessary, thereby avoiding unnecessary operations when the panel is already in the correct initial state.
Solution Approach 2:
The position detecting sensor provides feedback information about the panel's current position to the control apparatus. This feedback mechanism enables the system to make intelligent decisions about whether to perform the initial operation, optimizing the balance between reliability and time efficiency.
2Device complexity
If the panel state is not detected, then the system structure remains simple, but the panel may not be opened normally when stopped in an unknown state
Solution Approach 1:
The position detecting sensor automatically detects the panel's state and provides this information to the control apparatus without requiring manual intervention. The system uses this self-detected information to determine whether the initial operation is necessary, thereby maintaining simple operation while improving reliability.

AI summary
Problems to be Solved To minimize a time required for initial operation by judging necessity of the initial operation depending on a panel position. Means for Solution On a cabinet 3, there is provided a wind guide panel 20, which covers a front surface of the cabinet 3 whereon a blow out port 5 is formed, the panel being capable of being opened both upwardly and downwardly. A position detecting sensor is provided for detecting that the wind guide panel 20 is in an initial state. When the position detecting sensor 90 detects that the wind guide panel 20 is in the initial state, the wind guide panel 20 is opened without performing the initial operation. When the wind guide panel 20 is not in the initial state, the initial operation is performed, and the wind guide panel 20 is opened after being brought into the initial state.
