The invention provides a kitchen fireproof 
system, and relates to the field of fire extinguishing equipment. The kitchen fireproof 
system comprises a box, a 
central processing unit, a 
smoke exhausting monitoring device, a 
temperature monitoring device, an 
alarm device, a gas valve control device, a 
smoke exhaust fan switch control device, a 
smoke hood air outlet valve control device, a 
flue spraying device and a cooking bench fire extinguishing device. The 
central processing unit is located in the box, and a temperature detecting device is electrically connected with the 
central processing unit and transmits temperature signals to the central 
processing unit. The smoke exhausting monitoring device is electrically connected with the central 
processing unit, and the central 
processing unit is electrically connected with the 
alarm device, the gas valve control device, the smoke exhaust fan switch control device, the 
smoke hood air outlet valve control device, the 
flue spraying device and the cooking bench fire extinguishing device. The kitchen fireproof 
system solves the technical problems that in the prior art, a kitchen fireproof system cannot extinguish fire immediately, and 
flue fire extinguishment cannot be directly conducted.
