AI Technical Summary
In existing range hoods, the surface of the infrared or ultrasonic sensor probes is easily covered with oil in oily environments, leading to a decrease in the accuracy of the oil level detection results.
The system employs a floating component and a ball level switch component. The floating component floats on the surface of the liquid oil in the oil cup, while the ball level switch component is connected to the detection electrode. The system detects whether the oil level in the oil cup has reached the upper limit level by monitoring the working status of the detection circuit.
It improves the accuracy of oil level detection, avoids the influence of oil fume environment on detection, and ensures the reliability of oil quantity detection.
