Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compressors in dehumidifiers and air conditioners are prone to overheating and burning out due to inaccurate temperature detection, with existing methods failing to effectively monitor the coil and connecting wires' temperatures, leading to a high risk of fire.
Innovation Solution
A compressor design with a terminal cover, mounting base, and wire outlet seat that incorporates first and second temperature detecting devices to accurately measure the temperature at the top of the compressor and the connecting wires, respectively, along with a control method that powers the compressor on and off based on preset thresholds to prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature detecting device is disposed on the exhaust pipe of the compressor to detect the exhaust temperature, then the compressor frequency can be adjusted to protect the compressor, but the detected temperature is not the actual temperature of the coil, so the compressor is still in danger of being burnt out
Solution Approach 1:
The patent introduces an aluminum alloy mounting base as an intermediary thermal conductor that directly contacts the compressor coil. This mounting base serves as a mediator to transfer the coil's temperature to the temperature detecting device, enabling accurate temperature measurement without direct contact between the detector and the coil, thus resolving the contradiction between detection accuracy and protection effectiveness.
2Ease of manufacture
If three connecting wires of a conventional compressor are bundled together by a PVC protective sleeve, then the wires are led out together to be connected to a power supply, but this structure concentrates the heat generated among the three connecting wires, resulting in that the connecting wires are liable to burn out due to over high temperature
Solution Approach 1:
The patent segments the connecting wires by providing separate wire outlet seats for each wire instead of bundling them together in a PVC sleeve. Each wire has its own outlet seat and temperature detecting device, which separates the heat sources and prevents heat concentration, while still maintaining ease of manufacture through modular wire outlet seat design.
3Power
If the working current of the conventional compressor is large, then the connecting wires will be heated, but when the working time is quite long or when the large current flows by the connecting wires, it is possible the connecting wires are burnt out due to overheat
Solution Approach 1:
The patent implements a feedback mechanism by providing temperature detecting devices that continuously monitor the temperature of each connecting wire. When the temperature exceeds a preset threshold, the system provides feedback to reduce or stop the compressor operation, preventing the connecting wires from burning out due to prolonged high current operation.
