Description

Automatic fire extinguishing

The present invention relates to an automatic fire extinguishing device capable of automatically extinguishing a fire in the event of a fire, and more particularly, to the structure of a spray nozzle and a temperature sensor of the automatic fire extinguishing device.

In general, a fire extinguisher is installed in a place exposed to a fire risk, such as a kitchen in a home or a kitchen counter in a restaurant.

The fire extinguisher should be equipped with a system that automatically detects the fire when a fire occurs, to extinguish the fire by injecting the extinguishing fluid material of the fire extinguisher, to shut off the valve of the fuel pipe, and to ring a fire alarm.

An example of a structure of a conventional automatic fire extinguisher equipped with the above system is a schematic front view of a state in which a conventional automatic fire extinguishing system is installed in a kitchen of a home, and FIG. 2, which illustrates a three-dimensional structure of the extrusion bar 5 of FIG. 1. 3 will be described with reference to FIG. 3 showing the front detail of the extrusion bar 5 of FIG. 1 and FIG. 4 showing the coupling state of the operation box and the fire extinguisher head.

The fire extinguisher main body equipped with the fire extinguisher 2 and the fire extinguisher operation box 3 mounted on the head 22 of the fire extinguisher is disposed in the space 57 above the range hood 56 to discharge the smell and smoke generated when cooking. An extrusion bar 5 equipped with a nozzle 15, a temperature sensor 29 and a fuse link 21 is fixed to the bottom of the range hood 56. The control box 60 is disposed in the space of the storage cabinet 80, the gas circuit breaker 30 is installed at an appropriate position of the outer wall or the inner wall, and the gas leakage alarm 50 is installed at an appropriate position of the inner wall.

In the automatic fire extinguisher system configured as described above, the injection nozzle 15 of the head 22 and the extruding bar 5 of the fire extinguisher is connected by a connecting tube 16, and the operation wire 3 of the outer shell 100a on which the working wire 100 is slidable. One end is fixed, and the other end of the outer shell 100a is fixed to the extrusion bar 5. One end of the operation wire 100 drawn out of the inner shell 100a is connected to the fuse link 21 configured in the extrusion bar 5, and the fuse link 21 is fixed to the wall of the extrusion bar 5. The other end of the operation wire 100 drawn out from the inside of the outer shell 100a is fixed to the tenbuckle 41 of the operation box 3, and the tenbuckle is fixed to the upper part of the lever 91. The lever 91 is connected to the spring 92 fixed to the wall of the operation box 3, the center portion is fixed by the lever pin 43. The lever pin 43 is fixed to the wall of the operation box 3, the lever 91 is pivotable around the lever pin, and the lower end 44 of the lever 91 does not press the upper end 17 of the operation pin 25 installed on the fire extinguisher head 22. The tension force is maintained by the action of the wire 100. In particular, the adjustment of the tensile force can be finely adjusted by adjusting the length of the working wire 100 by the tenbuckle 41.

On the other hand, the fire extinguisher head 22 is provided with a connecting passage 66 to move the extinguishing fluid in the interior of the extinguisher 2 to the connecting pipe 16 connected to the injection nozzle 15, as shown in Figure 4, the operation pin 25 is inserted into the connecting passage 66 The lower end of the operation pin blocks the central portion of the connecting passage 66 by the action of the spring 52. The pressure gauge 93 is provided in communication with the connecting passage 66.

In addition, the control box 60 of FIG. 1 is connected to a sensor line 20 drawn out from the temperature sensor 29, and a pressure sensing line 88 drawn out from the pressure gauge 93 of the fire extinguisher head unit is connected to detect the pressure state of the fire extinguisher 2. The gas leakage alarm signal line 51 drawn out from the gas leakage alarm 50 is connected, and the gas shutoff signal line 31 drawn out from the gas circuit breaker 30 is connected. Inside the control box, a board having a function of providing information on the gas leakage alarm 50 and the gas circuit breaker 30 by checking the pressure state of the fire extinguisher 2 and the signal of the temperature sensor 29 is embedded.

In a state where a fire has not occurred, that is, the fire extinguisher system described above is normally maintained and the fire is generated from a gas range or the like due to other factors, or to go out with the gas range 46 turned on. In the first case, when the temperature sensor 29 detects a flame of a fire and supplies a signal to the control box 60, the gas circuit breaker 30 automatically operates to lock the gas valve and operate the gas leakage alarm 50. Subsequently, when the fuse link 21 is melted and broken by the flame, the actuation wire 100 connected to the fuse link 21 is pulled toward the operation box 3, and thus the tension force which has been balanced based on the lever 91 loses the balance. The lever 91 rotates counterclockwise with respect to the lever pin 43. In other words, the end 44 of the lever is moved toward the upper end of the operating pin 17, and the connecting passage 66 is opened by pressing the operating pin downward, and the extinguishing fluid stored and stored inside the fire extinguisher 2 is injected through the connecting tube 16 and the fire is started early. Battling on.

By the way, the conventional automatic fire extinguisher system configured as described above is complicated in the installation process because the outer shell 100a of the operation wire line to be fixed to the operation box 3 and the extrusion bar 5 as shown in the structure of Figures 1 and 4, the outer shell 100a There is a problem that must be provided with an extrusion bar 5 and a fuse link 21 that can be fixed.

In addition, since the injection nozzle, fuse blow, and the temperature sensor is fixed to the extrusion bar, the position of the parts such as the injection nozzle and the temperature sensor is determined according to the installation position of the extrusion bar, so it is difficult to adjust the injection angle of the extinguishing material.

In addition, due to the weight of the extrusion bar, there is a problem in that the extrusion bar sag downwards, thereby deteriorating the aesthetics of the kitchen.

The present invention is to solve the above problems, the structure of the extrusion bar 5 and the operation wire 100 and the outer wire 100a, fuselink 21 is removed by removing the system of the conventional automatic fire extinguishing device that requires the configuration of the extrusion bar The fire extinguisher system and the temperature sensor are fixed at the bottom of the range hood 56.

In particular, the injection nozzle is configured and attached so that the user can adjust the injection angle of the extinguishing fluid, the temperature sensor is attached to the range hood or the like using a support on which a magnet is fixed.

Therefore, the present invention aims to improve the installation workability and appearance of the system by structuring the system of the automatic fire extinguishing device that does not require an extrusion bar, so that the position of the injection nozzle and the temperature sensor can be optimally positioned. do.
