In such a configuration, it is possible to extinguish the fire more quickly because the fireballs of the cooking utensil 10 in which the fire is generated can be intensively extinguished. In addition, all the spray nozzles 50 may be configured to be connected to the extinguishing agent supply unit 60, respectively.

3 is a schematic configuration diagram of a fire suppression apparatus according to a third embodiment of the present invention.

3, the fire suppression apparatus according to the third embodiment of the present invention is distinguished in that the auxiliary fire extinguishing agent supply unit 100 is further included in the first embodiment.

Auxiliary fire extinguishing agent supply unit 100 is connected to the connection pipe 70, and the extinguishing agent is filled like the extinguishing agent supply unit 60. And, between the connection pipe 70 and the auxiliary fire extinguishing agent supply unit 100 is an auxiliary fire extinguishing valve 102 that controls the supply of the extinguishing agent filled in the auxiliary fire extinguishing agent supply unit 100 to the connection pipe 70 is provided. Is placed.

This third embodiment may be useful when a fire occurs in the various cooking utensils 10.

When a fire occurs in any one of the plurality of cooking utensils 10, that is, when the sensing temperature of any one of the plurality of temperature sensor 40 is detected above the first set temperature, the control unit Under the control of 90, the on / off valve 80 connected to the injection nozzle 50 corresponding to the temperature sensing sensor 40 whose sensing temperature is equal to or greater than the first set temperature is opened. At this time, the extinguishing agent valve 62 may also be opened under the control of the controller 90. In this operation, the extinguishing agent filled in the extinguishing agent supply unit 60 is supplied to the cooking utensil 10 in which the fire is generated and sprayed.

In such a situation, a fire may occur in another cooking utensil 10. That is, the sensing temperature of the other one of the plurality of temperature sensors 40 is detected above the first set temperature. Accordingly, the control unit 90 similarly opens another on-off valve 80 to extinguish the fire of the other cooking utensils 10.

By the way, when extinguishing agent is being supplied from the extinguishing agent supply unit 60 to extinguish the fire that has already occurred, the pressure for supplying the extinguishing agent is divided when another open / close valve 80 is opened. In other words, the pressure for supplying the extinguishing agent drops so that the extinguishing agent is not supplied sufficiently, so that the first fire cannot be suppressed properly, and the later fire cannot be suppressed properly.

Therefore, the fire extinguishing agent is not supplied by the auxiliary fire extinguishing valve 102 in a normal manner with the auxiliary fire extinguishing agent supply unit 100, and as described above, when the fire occurs frequently, the control of the control unit 90 In accordance with the auxiliary fire extinguishing valve 102 is to be able to extinguish the fire.

If the temperature detected by all the temperature sensor 40 is less than the second set temperature, the control unit 90 does not perform any other operation, but if any one of the plurality of temperature sensor 40 of the temperature sensor 40 2, when the set temperature or more is detected, the control unit 90 cuts off the electricity supply, cuts off the gas supply, and senses the second temperature of the cooking utensil 10 corresponding to the temperature sensing sensor 40 whose sensing temperature is greater than or equal to the second set temperature. Closing the duct 30 through the damper 32 of the duct 30 corresponding to the temperature sensor 40 above the set temperature. At this time, depending on the situation may be performed in various ways, such as blocking only the electricity supply, or only the gas supply.

In addition, the control unit 90 issues a primary alarm (electricity, gas shutoff notification, etc.) through the alarm. The primary alarm may be issued before the electric power supply cutoff, the gas supply cutoff, and the duct closing of the cooking appliance 10 are performed, or may be issued at the same time.

Subsequently, when one or more of the first set temperature is detected by any one of the plurality of temperature sensors 40, the controller 90 causes a second alarm (notification of fire occurrence) to be issued. The extinguishing agent is injected through the injection nozzle 50 by controlling the open / close valve 80 corresponding to the temperature sensor 40 having a sensing temperature greater than or equal to the first set temperature to be opened. In other words, by selecting the cooking utensil 10 in which the fire occurred can be quickly put out the fire.

On the other hand, in the present invention, an emergency button (not shown) for manually injecting a fire extinguishing agent or a communication module (not shown) for informing the administrator of the current state may be arranged, such as an LCD display.
