From the national compulsory gas cooker must with flame-out protection device, the kitchen product that sells on the market have increased in the flame-out protection device. When add the flameout protection device in the kitchen, will bring some not accustomed to using on to the user; At the same time also increased the point of failure, repair difficulty also increase accordingly.
1 the characteristics of the thermocouple flame-out protection device
Intuitive judgment whether a stove using thermocouple flame-out protection device, in general, through the probe, the watch battery, you know. Thermocouple flame-out protection device has two obvious features:
(a) a kitchen fire on each side cover (also known as firearms) fixed on the side of a copper cylinder probe, probe the top stainless steel for a while. Probe the basic high with points of firearms.
(2) using thermocouples embedded cooker, flame-out protection device normally just section 1 battery; Desktop kitchen general without the battery.
2 the working principle of thermocouple flame-out protection device
Thermocouple flame-out protection device of the electric schematic diagram is shown in figure 1, thermocouple flame-out protection device is mainly composed of two devices, one is a thermocouple, another is the electromagnetic valve. Thermocouples used for induction heat, flame and transform heat into electricity, to the solenoid valve, and provide energy for electromagnetic valve and; Electromagnetic valve by accepting thermocouples provide energy, open or closed gas path.
