The first gas stove to launch anti-dry burning technology was Haier. Haier's intelligent temperature probe has 28 patented technologies for preventing dry burning. It can automatically detect the temperature of the bottom of the pot. Once it is found that the temperature of the bottom of the pot exceeds 298°C, it will automatically turn off the flame for protection. At the same time, the gas stove can also detect when the stove accidentally flames out or the fire does not sit on the pot for a long time, and can cut off the gas source as soon as possible to avoid accidents.
The above-mentioned technology is not yet a mandatory standard configuration for civilian gas stoves. What is currently available is a flameout protection device.
The main function of the gas stove flameout protection device is to close the gas channel when the gas stove is not working, or when the gas accidentally flames out during use, to avoid accidental gas leakage. Common gas stove flameout protection devices mainly include thermocouple flameout protection devices and self-priming valve flameout protection devices.
Dry burn prevention and flameout protection are not the same thing. If the fire is too big and the water overflows and extinguishes the gas stove, the automatic flameout device can be activated.
