Generally speaking, a kitchen is a space for cooking, so there is a danger of fire because it is directly related to fire. In particular, gas leakage or electric fire overheating often occurs in kitchens of homes and restaurants, due to inadvertent use of electric plugs and gas ranges, and the resulting damage to people and property is enormous. In order to prevent such a fire, general fire extinguishers are provided at home or restaurants, but there are many problems in use due to lack of knowing when and where fire occurs, and in case of not providing fire extinguishers or managing fire extinguishers, . In addition, the fire is independent of the time and place, independent office space on each floor, closed karaoke room, factory interior, PC room, closed jumjilbang room, private room in motel or back door inn, small room It is no exaggeration to say that at night there is virtually fire defenseless because facilities and spaces that do not have fire-fighting facilities such as sprinklers are inundated in the academy space and various commercial facility spaces.

As the supply of gas and electric range appliances increases, the government imposes additional legislation on the fire extinguishing system standard and requires the fire extinguisher to be installed under the Act (National Security Administration Notice No. 2015-000). However, Even if you want to install a fire extinguishing system such as a sprinkler as well as a surprise, there is no space to install or a fire extinguishing system itself. In particular, a means of responding to a fire occurring at night is almost not defensible Do. In spite of these circumstances, the company is still concentrating its efforts on developing measures to cope with the fire of gas and electric ranges.

For example, Korean Patent Laid-Open Publication No. 2011-0112514 discloses a fire extinguishing system for fire fighting a kitchen, wherein the fire extinguishing system 100 includes a plurality of spray nozzles 11, A fire extinguishing piping 10 which is branched and arranged; A drug storage container 20 connected to the fire extinguishment pipe 10 and having an injection plug 22 for injecting medicines and nitrogen gas in an upper portion thereof; A coupler (30) connected to the injection plug (22) of the medicine storage container (20) and having a diaphragm (31) intercepted from the inside of the injection plug; A connection pipe body 40 connected to the fire extinguishment pipe 10 at one side while being connected to the coupler 30; A first installation space portion 51 is formed on the inside and a second installation space portion 51 formed on the lower side of the first installation space portion 51 and formed with a guide hole 52a from the outside, (50) having a partition (52) partitioning the partition (53); A connection support unit 60 screwed to the front end of the second installation space part 52 of the housing 50 and having an inner diameter formed with a joint pipe 62 for interconnecting the connection pipe body 40; A solenoid (70) installed in the first installation space (51) of the housing (50) and slidably driving the actuating shaft (71) in response to an alarm signal generated in a kitchen fire; The diaphragm 31 of the coupler 30 is ruptured according to the operation of the solenoid 70 so as to extinguish the compressed and stored medicine from the medicine storage container 20, A medicine supply member (80) for supplying the medicine to the injection tube (10) side; A fixing member which is provided from the first installation space portion 51 of the housing 50 and which holds or releases the medicine supply member 80 in the second installation space portion 52 through the partition 53, 90); A manual adjusting member 110 installed from the outside of the housing 50 for manually actuating an operating shaft 71 of the solenoid 70; And an installation box (120) for accommodating the remaining components except the part of the fire extinguishant pipe (10).

However, the above-described automatic and manual fire extinguishing systems for fire fighting kitchens are required to maintain a perfect standby state for a fire to occur sometime, and the complicated structure is accompanied with inconvenient problems when frequent inspections and repairs are required.

In the present invention, the office space of each floor, the closed karaoke room, the closed space of the factory, the PC room, the closed room, the private room, the small institute space, and various commercial facilities The present invention relates to a ceiling fire extinguisher system for preventing a fire generated in a facility or a space portion having no fire extinguishing equipment such as a sprinkler and includes a delivery portion 10, a fluid portion 20, a hydraulic pressure supply portion 30, 40, and a control unit 50 as main components. However, in the present invention, for convenience of explanation, the case of installation of a kitchen, that is, an installation example of a ceiling fire extinguisher system to prevent a fire through an electric or gas range (1) and a hood (H) .

The dispensing section 10 according to the present invention can be applied to a building interlayer slab (interlayer slab) on the upper side of the gas range 1, as in the case shown in Figs. 1, 2C and 3C, between interlayer slabs And a spraying means 15 including a piston 13 for spraying the extinguishing medicament 11 inside through the high-pressure gas 12. [ The dispensing section 10 is located at or below the space section 62 between the slabs 60 between the building layers and the inside of the dispensing section 10 is held in a state accommodating the extinguishing medicament 11. In other words, the feeder 10 is installed between the interlayers of the respective buildings. Specifically, the feeder 10 is installed between the interlayer slab 60 and the ceiling finishing plate 61 disposed immediately below the interlayer slab 60 And in some cases, it may be installed in a place where the ceiling finishing plate 61 is not provided. The ceiling finishing plate 61 is generally installed at an interval of about 30 to 60 cm at the bottom of the interlayer slab 60. In the space 62 formed at this time, Rest. In addition, there is no problem to place the feeding portion 10 which can be manufactured with a size of about 10 to 15 cm (which can be made smaller or larger) even if the space portion 62 has a spacing of about 15 to 30 cm, Even if the spacing of the space 62 is very narrow, such as 10 cm or less, only a small part of the ceiling finishing plate 61 can be seamed and put on the ceiling, ) Is almost no problem. The dispensing unit 10 is provided with a spraying unit 15 therein so that the extinguishing medicament 11 accommodated in the dispensing unit 10 can be sprayed through the spraying unit 15. The spraying means 15 has the extinguishing medicament 11 inserted in the delivery portion 10 in the forward direction (direction in which the extinguishing medium flows) with the piston 13 as the center, And the high-pressure gas 12 is put in place.

The spraying means 15 of the dispensing section 10 includes a piston 13 which is bent in an elliptical shape so as to smoothly receive the pressure of the high pressure gas 12 and press the extinguishing medicament 11 to the front side, And a packing (14) for preventing the extinguishing chemical agent (11) and the high - pressure gas (12) from flowing out on the contact surface of the piston (13). The piston 13 of the spraying means 15 is in the form of an ellipse bent in the front direction in which the extinguishing medicament 11 is accommodated. This is because the pressing force is applied to the extinguishing medicament 11 accommodated in the dispensing portion 10, So that the extinguishing medicament 11 must be sprayed to the outside. That is, although it may be formed in the form of a flat plate or a triangle, it is considered that the pressure for pushing the digestive medicine material 11 filled with the elliptical shape rather than the flat plate shape is more dense and strong, The fire extinguishing agent 11 is strongly injected to the point where the fire occurs. In addition, a plurality of packings 14 are pressed against the piston 13 to prevent leakage of the high-pressure gas 12 accommodated in the rear portion.

The fluidizing section 20 according to the present invention communicates with the forward part of the delivery section 10 and discharges the extinguishing medicament 11 to the discharge port 21 with the aid of the jetting means 15, And performs a function of filling the extinguishing medicament 11 back into the dispenser 10 through the dispensing opening 21. That is, the moving part 20 communicates with the forward part of the feeding part 10 and the front hose 24 to spray the extinguishing medicament 11 to the outside, and the gas range 1, Or a hood H formed at the upper side of the fire wall (or a place where the risk of fire occurrence is high), but it is preferably installed at a position corresponding to the eye level of the user. When the extinguishing medicament 11 accommodated in the delivery portion 10 is sprayed, the flow portion 20 is configured to be distributed at a radius of about 30 to 170 degrees from the point of fire occurrence.

In addition, the hydraulic pressure supply unit 30 according to the present invention is provided so as to communicate with the rear of the delivery unit 10 and to be able to fill the high pressure gas 12. The hydraulic pressure supply unit 30 is configured to more conveniently fill the high pressure gas 12 used due to fire or oil leakage and can be filled directly in the rear portion of the delivery portion 10 However, the fluid can be filled through the rear hose 32 in the fluid portion 20 and the plug 31 is fastened to the fluid pressure supply portion 30 so as to prevent gas leakage.

The flow unit 20 includes a pressure gauge 22 for checking internal pressure and a pressure check valve 23 for communicating with the hydraulic pressure supply unit 30 to facilitate filling of the high pressure gas 12. [ And further comprising: The moving part 20 is provided with the extinguishing medicament 11 accommodated in the dispensing part 10 by the user and the pressure gauge 22 so that the pressure of the high pressure gas 12 can be directly visually confirmed, It is possible to hasten filling of the extinguishing medium 11 and the high-pressure gas 12 that have already been lost in the high-pressure gas, and an accident such as explosion due to high pressure can be prevented in advance. The high pressure gas 12 may be filled directly into the delivery section 10 or through the rear hose 32. In the case of filling through the rear hose 32, Pressure gas (12) can be filled in a compact and convenient manner through the gas-liquid separator (22).

The cover part 40 according to the present invention keeps the discharge port 21 in a sealed state on the moving part 20 and discharges the extinguishing medicament 11 from the discharge port 21 by heat in the event of a fire The fusible metal member 41 is provided. The cover portion 40 is normally kept in a state in which the discharge port 21 is sealed through the fusible metal material 41. When the temperature of the inside of the kitchen (or another room other than the kitchen) The fusible metal material 41 is gradually or rapidly melted down through the temperature of the heat of the fire or the like and then the cover part 40 which has closed the discharge port 21 is separated and dropped down, The fire extinguishing agent 11 of the delivery portion 10 is strongly injected to the point of fire occurrence through the flow portion 20 because of the piston 13 pushed forward by the high pressure gas 12. The above-mentioned fusible metal material 41 is a metal material that melts in response to a high temperature, and includes lead and the like, which is a metal material having a higher strength than that of lead.

Meanwhile, the control unit 50 according to the present invention includes sensor means for collecting information such as a fire temperature. The control unit 50 collects information such as a fire temperature and smoke generated in the kitchen (or another indoor space other than the kitchen) and transmits the collected information to the user (building owner), and the electric and gas range 1 and the hood H It is possible to prevent the second accident through the first fire and the fire in advance. The control unit 50 may be installed inside the kitchen (another room) so that the user can check it. However, the control unit 50 may be installed in a separate management place in order to prevent a breakage problem in case of fire. The control unit 50 can display the amount of the extinguishing chemical 11 and the amount of the high-pressure gas 12 and the pressure value in the delivery unit 10 through a display (not shown) It may be more smooth.

The sensor means of the control unit 50 senses a fire temperature or smoke or the like in the fluid 20 so that the first sensor 30 electrically isolates the range 1, the hood H, (51a). The first sensing sensor 51a of the control unit 50 is formed in the moving unit 20 and interlocks with the control unit 50 in the event of a fire so that the primary power source or the power source such as the range 1 and the hood H is shut off So as to prevent secondary accidents. The first sensing sensor 51a transmits the information to the controller 50 when the temperature of the fire sensor 51a reaches about 70 to 120 ° C at the time of the occurrence of a fire, and the controller 50 controls the range 1, the hood H, The power of the power source is blocked at once.

The sensor means of the control unit 50 senses a fire temperature or smoke in the moving unit 20 and activates the heating heater 52 installed close to the cover unit 40 so that the automatic deviation of the cover unit 40 And a second sensor 51b is provided so as to enable the second sensor 51b. When the cover 40 is sealed by the fusible metal member 41 and the discharge port 21 or the like and the cover 40 is released from the flow portion 20 when a fire occurs and the fire extinguishing agent 11 is sprayed It is possible to automatically perform the separation of the cover portion 40 through the second sensor 51b of the sensor means in the embodiment of the heating heater 52. [ That is, the heating heater 52 is attached to the moving part 20 at a position close to the cover part 40, and when the second sensing sensor 51b confirms the temperature of about 70 to 120 ° C in the event of fire, The control unit 50 transmits the information to the control unit 50. The control unit 50 receives the information and operates the heating heater 52 installed close to the cover unit 40 so that the fusible metal member 41 The covering portion 40 is removed through the heat of the heating heater 52 so that the extinguishing medicament 11 of the delivering portion 10 can be sprayed through the moving portion 20. [
