Description
Technical field
The utility model is related to gas-cooker security technology area, specifically a kind of.
Background technology
At present, what gas-cooker was applied in the life of people is more and more extensive, because gas-cooker mainly uses various combustions
Gas burning obtains heat, and existing various combustion gas such as natural gas, manufactured gas, manufactured fuel gas, liquefied petroleum gas, biogas etc. all have to human body
Certain toxic action, imappropriate use will trigger serious security incident, therefore the various function of safety protection of gas-cooker are more next
More it is valued by the people, especially the burning prevention function of gas-cooker.A kind of Chinese patent application " anti-dry heating gas-cooker " (application
Number 2009100991022) to disclose a kind of anti-dry technology, its technical scheme is that an induction installation is provided with stove,
It is connected with electronic switch, is installed on wherein pressure inductor, alarm device and timer using exotic material, by control
Device sets an interval time, human body proximity and when operating stove, and pressure inductor can perceive and record is left on timer, when
Over-time be spaced and pressure inductor be still not sensed by next time human body operate when, timer passes information to alarm device
And electronic switch, sound the alarm and will then enter Gas Pipe closing, it is so as to reach the function of anti-dry but this with " between the time
Every " for control signal burning prevention function it is not direct enough, also not sensitive enough, real-time is poor, and exist in use it is many
Inconvenience, the situation for a long time of dry combustion method may be caused if time interval setting is long, and security is poor；If time interval was set
It is short, may influence normally to use, these shortcomings greatly limit the security and practicality of burning prevention function.
In order to solve the above-mentioned technical problem, CN201652487 U disclose a kind of burned protection device for gas oven, it discloses
The burner of gas-cooker, sensor detection hole is provided with the center of the burner, is provided with for examining in sensor detection hole
