Background technique
With the development of society and the raising of living standards of the people, people to the security requirement of house life also increasingly
It is high.Currently, the product for cooking fire safety monitoring mainly use smoke alarm, infrared or ultraviolet fire detector and
Some fire detection equipments that image recognition is carried out by camera, and work with torches and a large amount of is natively had kitchen is this
Smog generates the place of (the normal oil smoke generated when culinary art), and fire detection equipment is easy to cause to report by mistake.Above-mentioned fire detection is set
It is standby to belong to passive-type detecting devices, i.e., alarm operation can be just only generated when fire incident has occurred that, and at this time in fact
A degree of loss is had resulted in.In addition, not only being deposited using the fire detection equipment for carrying out image recognition by camera
Larger drawback is occupied at high cost, communication bandwidth, further relates to the risk that individual privacy is leaked, therefore is not also obtained a large amount of
It is widely applied.
When using kitchen kitchen range, it is typically necessary people and looks after, dry combustion method, soup or water to occur when preventing from cooking, cook
Spilling puts phenomena such as stove out by water.But in real life, cooker often occurs because of other affairs and kitchen away from keyboard,
In doing other business process, the food done on kitchen range can have usually been forgotten.Also, increasingly with the day of social senilization
Play, elderly population radix increasingly increases, and old man is with advancing age, and memory is gradually failed, and necessarily causes because leaving kitchen
Overlong time forgets that the situation for closing fire can be stepped up, this means that forgetting the important hidden danger of this fiery family kitchen fire of pass
Also it can be stepped up.Currently, the product of kitchen timer etc is had on the market, by being configured to kitchen timer
Forget to close fiery situation when user being avoided to leave kitchen.But the unlatching of kitchen timer, closing, the time setting be both needed to very important person
To participate in manually, otherwise cannot work.So even if having purchased kitchen timer product, can not solve at all because
Forget to close security risk caused by fire.
Utility model content
The purpose of this utility model is that: to solve to cause fire due to kitchen leaves personnel and dryout kitchen range for a long time
Problem provides a kind of active cooking fire prevention warning device.This prevention warning device is mainly sensed by infrared array
