Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dehumidifiers lack intelligent overload protection, leading to reduced product reliability and safety due to severe working conditions, which can cause the compressor to overheat and shorten the device's lifespan.
Innovation Solution
A dehumidifier control method and apparatus that collects environment temperature and humidity parameters to determine the running mode, adjusting fan and compressor operations based on pre-set conditions to prevent overloading, including shifting to high wind gear and implementing start-stop cycles for the compressor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the dehumidifier runs continuously under severe working conditions to maintain dehumidification performance, then the dehumidification effectiveness is improved, but the compressor overheats and product reliability deteriorates
Solution Approach 1:
The patent implements periodic action by controlling the compressor to operate in cycles rather than continuously. When severe working conditions are detected (high outlet air temperature and high condensing pressure), the control device stops the compressor for a predetermined period, then restarts it. This periodic operation allows the compressor to cool down during stop periods while still maintaining dehumidification functionality during run periods, thereby preventing overheating and improving reliability without completely sacrificing productivity.
2Device complexity
If the dehumidifier operates without intelligent protection logic to maintain simple control, then the device complexity is reduced, but the compressor suffers from severe working conditions and product reliability deteriorates
Solution Approach 1:
The patent applies feedback principle by implementing a control device that continuously monitors working conditions through sensors detecting outlet air temperature and condensing pressure. When these parameters indicate severe working conditions, the control device automatically adjusts compressor operation by stopping and restarting it according to predetermined logic. This feedback-based intelligent protection mechanism enhances reliability without requiring complex manual intervention, as the system self-regulates based on real-time condition monitoring.
3Productivity
If the dehumidifier runs under high outlet air temperature and high condensing pressure to maintain dehumidification capacity, then the dehumidification performance is improved, but the compressor overheats and product reliability deteriorates
Solution Approach 1:
The patent implements preliminary anti-action by proactively detecting severe working conditions through monitoring outlet air temperature and condensing pressure before the compressor actually overheats or fails. When these parameters exceed predetermined thresholds indicating severe conditions, the control device preemptively stops the compressor to prevent overheating. This preventive approach allows the system to maintain optimal temperature ranges while preserving dehumidification capacity during normal operation, as the protection mechanism activates only when necessary.
