Method for controlling start of purification function of air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The air purification function in air conditioners often goes unused due to manual activation, leading to inefficiencies and potential neglect in air quality improvement.
Innovation Solution
A method that automatically reminds and activates the purification function based on preset time intervals and user preferences, updating the purification cycle dynamically and allowing for automatic operation when the function has been inactive for an extended period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the purification function is activated manually, then the user has control over operation timing, but the purification function is often neglected and goes unused
Solution Approach 1:
The air conditioner system automatically monitors its own operation status and purification cycle completion, then autonomously determines when to activate the purification function without requiring manual user input. The control module tracks running time and automatically initiates purification based on preset cycles.
Solution Approach 2:
The system performs preliminary monitoring of operation time and purification cycle status before activation is needed. The control module continuously tracks whether the running time has reached the purification cycle threshold, preparing to activate purification automatically when conditions are met.
2Reliability
If the purification function operates continuously, then air quality is maintained, but energy consumption increases
Solution Approach 1:
The purification function operates periodically based on preset cycles rather than continuously. The control module activates purification when the running time reaches the purification cycle threshold, then stops after a predetermined duration, creating periodic operation patterns that balance air quality maintenance with energy conservation.
Solution Approach 2:
The system uses feedback from tracking the air conditioner's running time and purification cycle completion status to control activation. The control module receives feedback on whether the purification cycle has been completed and automatically determines the next activation timing based on this feedback.
3Productivity
If the purification function is activated automatically based on time intervals, then purification efficiency improves, but the system complexity increases
Solution Approach 1:
The control module performs multiple functions: it monitors running time, tracks purification cycle completion, determines activation timing, and controls purification activation. By making the control module multi-functional, the patent avoids adding separate dedicated components for each function, thereby limiting the increase in system complexity.

AI summary
A method for controlling the start of a purification function of an air conditioner. The method comprises: step A, starting an air conditioner to acquire a first time (TK); step B, calculating a time interval (T1) between the first time (TK) and a time (TX) when the air conditioner completes the previous instance of a purification function, and determining whether the time interval (T1) is greater than or equal to a first preset duration (T2), if so, proceeding to step E, and otherwise, proceeding to step C; step C, determining whether the time interval (T1) is greater than an air purification cycle (T0), determining whether the time difference between the time interval (T1) and the air purification cycle (T0) is greater than a preset warning difference value (T3), and when the time interval (T1) is greater than the air purification cycle (T0) and the time difference between the time interval (T1) and the air purification cycle (T0) is greater than the preset warning difference value (T3), proceeding to step E; step E, determining whether the air conditioner is in a default purification mode, and if so, proceeding to step F; and step F, an air purification module of the air conditioner working, recording, when the air purification module completes the purification function, the time (TX) the purification function is completed, and updating the air purification cycle (T0).
