Description

Automatic disaster prevention system for kitchen {AUTOMATIC DISASTER PREVENTION SYSTEM FOR KITCHEN}

The following embodiments relate to an automatic disaster prevention system for a kitchen.

In buildings and apartment houses, automatic fire extinguishing devices for fire kitchens are installed in kitchens equipped with cooking facilities to detect fires and automatically spray fire extinguishing agents to be used for initial extinguishing. In the kitchen automatic fire extinguishing system, when a fire is detected, the valve is automatically opened, and the fire extinguishing agent inside the fire extinguisher is immediately sprayed to extinguish the fire at an early stage.

Various types of automatic fire extinguishing devices for kitchens are used, but parts are changed or damaged during storage, resulting in an inoperable state, or nozzle clogging caused by glass bulb fragments and valve failure due to mechanical automation during operation. A problem is occurring.

In addition, in case of an unexpected fire from the heating device used in the kitchen when a strong vibration such as an earthquake occurs, the fire extinguishing effect of the automatic fire extinguishing device for the kitchen may decrease as heat is continuously supplied through the heating device. Accordingly, there is a problem that automatic fire extinguishing operation becomes difficult.

In addition, gas-type heating devices such as gas ranges and electric heating devices such as induction exist as heating devices used in the kitchen. As there is no function to cut off heat sources according to each heating method of kitchen heating devices as well as automatic fire extinguishing, automatic fire extinguishing efficiency is improved. There is an insufficient problem.

Therefore, it is possible to control the operation of the heating device as well as the fire extinguishing operation when an earthquake is detected by interlocking with the kitchen heating device, and reliability of operation can be secured through simplification of the structure and operation, and according to the heating method of each heating device. There is a need for an automatic fire extinguishing device for the kitchen that can cut off the heat source.

The fire extinguishing actuator 500 is disposed adjacent to the glass bulb 210 and operates to damage the glass bulb 210 when power is applied. The vibration sensor 400 transmits a signal generated according to vibration detection to the controller 600. As the vibration sensor 400, a variety of known sensors capable of generating signals of different voltage values may be used according to changes in electrical connection due to movement according to vibration of a ball accommodated in the device. An input signal may be transmitted to the vibration sensor 400 at a preset period, for example, at a 1 ms period, and a signal generated from the vibration sensor 400 may be transmitted. The change pattern of the signal generated from the vibration sensor 400 for a predetermined period of time is compared with a pattern of a previous period or a preset pattern to determine whether a vibration has occurred and whether a strong vibration that can cause a fire such as an earthquake has occurred.
