The flame sensor in the oven is a key safety device that is mainly used to monitor the flame state during the gas combustion process and ensure the stability and safety of the flame.
The flame sensor is usually a small device installed inside the oven or near the flame. Its main function is to detect whether the flame exists normally after the gas is ignited. It usually consists of a pair of metal electrodes that are designed to form a closed circuit when the flame exists. When the gas is ignited, the flame touches these electrodes, closing the circuit so that the sensor can detect the presence of the flame.
The flame sensor determines whether the flame continues to exist by monitoring the closed state of the circuit. If the flame suddenly goes out or disappears for other reasons, the circuit will open and the sensor can detect the loss of the flame. This change in signal usually triggers the oven's automatic shutdown protection mechanism to prevent unburned gas from continuing to flow out, thereby improving the safety of the oven.
Modern ovens are also usually equipped with a microprocessor or controller to monitor the signal output by the flame sensor. If the flame is detected to be extinguished or abnormal, the control system may sound an alarm or stop the supply of gas to avoid fire or other safety problems.
The working principle of flame sensors is based on the effect of flame on the state of the circuit. They are usually designed to be highly sensitive and responsive to ensure that the oven can safely use gas for heating at all times. This technology not only increases the user's trust in the oven, but also improves the overall safety and reliability of use to a certain extent.
The main components of a gas oven are the structural parts, the panel and the bottom shell, which is, quite understandably, the main structure.Combustion system: fire cover, furnace head: the furnace head is generally made of cast iron or aluminum alloy. The gas and the ejected primary air enter and mix initially from the furnace head, and then mix again through the fire cover, and continuously spray from the fire hole of the fire cover. out to form continuous combustion.Ignition system: pulser, ignition porcelain needle: the pulser generates a high-voltage discharge device, and the ignition porcelain needle (with wire) guides the high voltage generated by the pulser to the discharge position of the designated fire cover to ignite the gas.
