Summary of the Invention

Problems to be Solved by the Invention

[0005] However, sprinkler equipment is arranged for floors above a certain number of floors or floors exceeding a certain area of a building. For floors not subject to sprinkler equipment, fire extinguishers and indoor fire hydrant equipment are arranged, but in the case of fire extinguishers and indoor fire hydrant equipment, the location may not be known during a fire, and there are many people who are not used to using fire extinguishers and indoor fire hydrant equipment, making it difficult to quickly and surely perform fire extinguishing operations in case of a fire.

[0006] Furthermore, sprinkler systems only activate when the temperature rise due to the hot airflow meets the activation conditions. Since they do not activate until the fire reaches a certain scale, there is a problem in that they do not necessarily enable early firefighting.

[0007] Furthermore, when a target area where sprinkler heads are installed is partitioned into sections such as conference rooms, the partition may include areas such as the ceiling where sprinkler heads are not installed. In the event of a fire, the water used to extinguish the fire from the activated sprinkler heads may be blocked by the partition, potentially leaving unprotected sections.

[0023] (Flexible fire extinguishing agent piping) Some or all of the fire extinguishing agent piping will be made of flexible fire extinguishing agent piping. [Effects of the Invention]

[0024] (Basic effects) In the fire extinguishing device of the present invention, a fire extinguishing agent distribution path is provided on at least one side of a partition, for example, a partition that physically constructs a boundary surface without changing the structure of the installation location, with multiple discharge ports for releasing the fire extinguishing agent located at various points. This allows for surface discharge of the fire extinguishing agent from multiple discharge ports located at various points on the boundary surface of the partition during a fire, securing a wider discharge range compared to the point discharge of conventional sprinkler heads where the installation location is the discharge point, and reducing the number of areas that could be damaged by water spraying, thereby enabling fire suppression and extinguishing with a small amount of fire extinguishing agent.

[0025] Furthermore, if the discharge port is designed to release the fire extinguishing agent perpendicular to the boundary surface of the partition, the fire extinguishing agent will be released sideways (towards the target area, for example, from the side of a room into the room), allowing the fire extinguishing agent to reach hidden locations such as under tables and desks placed in the room, ensuring that the fire is effectively suppressed and extinguished.

[0026] Furthermore, when the partitioning means is placed in a target area such as a room, it divides the placement area into two regions on either side of the boundary surface. It is limited in size to correspond to the height of a person or the height of the ceiling, and if the amount of extinguishing agent discharged from each outlet is less than that of a sprinkler head, then the extinguishing agent can be sprayed to every corner of the target area with a relatively small amount of extinguishing agent and relatively low pressure, making it possible to suppress and extinguish a fire in a predetermined area efficiently and in a short time.

[0027] (Effect of arranging the fire extinguishing agent distribution route relative to the discharge outlet row) Furthermore, by supplying the fire extinguishing agent from both ends of a discharge port array element, which has multiple discharge ports arranged along the interface, for example, in the lateral direction, it becomes possible to make the discharge pressure of the multiple discharge ports approximately uniform, and to standardize the discharge pattern (angle distribution) and discharge amount of the fire extinguishing agent.

[0028] (Effects of the configuration of partitioning means and the arrangement of fire extinguishing agent distribution routes) Furthermore, by constructing the partitioning mechanism with flat panel members and frame members, and by providing a fire extinguishing agent flow path in at least the panel members, it is possible to discharge the fire extinguishing agent from multiple discharge ports located at various points on the panel surface (boundary surface) of the panel members. In addition, if part or all of the panel surface (boundary surface) of the panel members is a glass window and is therefore unsuitable as a location for discharge ports, this can be addressed by providing a fire extinguishing agent flow path in the frame member and creating discharge ports therein.

[0029] (Effect of fire extinguishing agent discharge pipe) Furthermore, by arranging a fire extinguishing agent discharge pipe, which has multiple discharge ports arranged in the axial direction (on a single straight line in the horizontal direction) on the outer circumference, as part of the fire extinguishing agent distribution path provided in at least one of the panel member or frame member, a fire extinguishing agent distribution path with multiple discharge ports can be incorporated into the panel member or frame member that constitutes the partitioning means with a simple structure.

[0030] (Effects of fire extinguishing agent supply port and its connection configuration) Furthermore, by providing fire extinguishing agent supply ports on both sides of the partitioning mechanism, not only when a fire extinguishing device is placed individually, but also when multiple fire extinguishing devices are connected and placed together, the fire extinguishing agent from the fire extinguishing agent supply source is supplied sequentially to each fire extinguishing device, and the multiple fire extinguishing devices work together to release the fire extinguishing agent over a surface, thereby suppressing and extinguishing the fire.

[0031] (Effectiveness of fire extinguishing equipment in partitioned compartments with interconnected partitioning mechanisms) Furthermore, partitioning means, such as partitions, can be used to create partitioned areas within a room in an office building, etc., depending on its purpose, such as a reception room or a conference room. In such cases, if at least one of the partitioning means forming the partitioned area is equipped with a fire extinguishing device that has a fire extinguishing agent distribution path and multiple discharge ports, then in the event of a fire in the partitioned area, the fire extinguishing agent can be released from the partitioning means equipped as a fire extinguishing device to suppress and extinguish the fire.

[0032] (Effects of forming a fire extinguishing agent distribution route using a three-way switching mechanism) Furthermore, by providing a bypass distribution route that detours around the fire extinguishing agent distribution route, and by using three-way switching means provided for each of the fire extinguishing agent supply ports on both sides, when multiple partition means are connected and arranged, the discharge of fire extinguishing agent from all partition means and the discharge of fire extinguishing agent from some specific fire extinguishing agent construction means can be freely set by switching the three-way switching means.

[0033] Furthermore, in a building where sprinkler heads are installed, if there are no sprinkler heads installed on the ceiling of a section partitioned by multiple partitioning means, such as connecting partitions, water discharged from sprinkler heads installed on the ceiling outside the partitioned section will be blocked by the partitioning means and will not reach the partitioned section. However, if at least one of the partitioning means that divides the section functions as a fire extinguishing device, it is possible to reliably suppress and extinguish a fire that occurs in the partitioned section that divides the ceiling where no sprinkler heads are installed.

[0034] (Effectiveness of fire extinguishing system 1 using water pipes) Furthermore, by connecting water pipes to the fire extinguishing agent piping and releasing tap water as a fire extinguishing agent from the outlet of the fire extinguisher in the event of a fire, dedicated pump equipment becomes unnecessary, making installation easier and reducing costs.

[0035] (Effectiveness of fire extinguishing system 2 using fire extinguishers) Furthermore, by connecting a fire extinguishing agent supply device, such as the nozzle of a fire extinguisher, to the fire extinguishing agent supply port via fire extinguishing agent piping, and then opening the valve of the fire extinguisher when a fire occurs to release a predetermined fire extinguishing agent, such as a powder fire extinguishing agent or an enhanced liquid fire extinguishing agent, into the target area from the discharge port of the fire extinguishing device, it becomes possible to effectively suppress and extinguish the fire.

[0036] Furthermore, even if one is unfamiliar with handling fire extinguishers, which are fire extinguishing agent supply devices, simply removing the safety pin from a fire extinguisher located outside the room where the fire extinguishers are placed and squeezing the lever to open it will supply high-pressure fire extinguishing agent to the fire extinguishers inside the room and release it into the target area, making it possible to suppress and extinguish a fire quickly and effectively.

[0037] (Effectiveness of fire extinguishing system 3, which uses both fire extinguishers and water pipes) Furthermore, in addition to the effects of the aforementioned fire extinguishing system 1 using water pipes and fire extinguishing system 2 using fire extinguishers, when a fire occurs, the fire extinguishing agent supply device, such as a fire extinguisher, is opened to release the extinguishing agent into the target area, thereby performing initial fire suppression. The duration of extinguishing agent release by the fire extinguisher is short, for example, a few tens of seconds. However, if the fire suppression and extinguishing are insufficient, the pipe opening / closing mechanism is opened to release tap water into the target area from the outlet, continuing the fire suppression and extinguishing. Since there are no time constraints on the release of tap water, it is possible to reliably extinguish the fire that has been suppressed by the release of extinguishing agent from the fire extinguisher.

[0038] (Effects of the configuration of the pipe opening / closing mechanism) Furthermore, in fire extinguishing system 1 or 3, remote control based on a control signal from the fire detection equipment in response to a fire occurring in the target area allows the remote on-off valve to be opened, enabling the release of extinguishing agent from fire extinguishers linked to fire detection. Additionally, the release of extinguishing agent from fire extinguishers is also possible through manual opening of the on-off valve. This allows for faster activation and suppression of the fire than sprinkler heads, which operate in response to the hot airflow from the fire.

[0039] (Effects of the fire extinguisher connection method) Furthermore, since the fire extinguishers are detachably connected to the fire extinguishing agent piping by a connecting mechanism, when a fire extinguisher is used up, it can be replaced with an unused one as needed, thereby continuing the release of the fire extinguishing agent and enabling reliable fire suppression and extinguishing.

[0040] Furthermore, in the event of a fire outside the protected area where no fire extinguishing equipment is installed, the fire extinguisher can be detached using the connecting mechanism of the fire extinguishing agent piping, transported to the location, and used. This allows the normally installed fire extinguisher and the fire extinguisher for the fire extinguishing equipment to be used interchangeably, simplifying the maintenance of the fire extinguisher and reducing operating costs.

[0041] (Effects of flexible fire extinguishing agent piping) Furthermore, by using flexible fire extinguishing agent piping, such as fire extinguishing agent hoses, for part or all of the fire extinguishing agent piping, it becomes possible to flexibly respond to the movement or rearrangement of partitions, for example.

[Modes for carrying out the invention]

[0043] The embodiments of the disaster prevention equipment according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the embodiments described below.

[0044] [Basic Concepts of the Embodiments] First, the basic concepts of the embodiment will be explained. The embodiment generally relates to fire extinguishing equipment and fire extinguishing systems.

[0045] "Fire extinguishing equipment" refers to equipment used to suppress or extinguish fires by spraying or releasing extinguishing agents. This concept includes, for example, fire extinguishers and fire hydrants that are placed in a target area and used in firefighting activities when a fire occurs. Here, "suppressing or extinguishing a fire" combines the concepts of suppressing a fire and extinguishing a fire. For example, "fire suppression" refers to the concept of suppressing the spread of a fire, the rate of combustion of flames, or the scale of flames, while "fire extinguishing" refers to the concept of putting out the combustion. Of course, this also includes cases where only one of these is performed. Furthermore, "target area" refers to the area where the fire extinguishing equipment is placed. This includes, for example, the external area outside the building and the internal area inside the building. The internal area inside the building includes rooms, corridors, stairwells, etc. Furthermore, "firefighting activity" refers to the actions of people using fire extinguishing equipment to suppress or extinguish a fire. This concept includes, for example, initial firefighting carried out by fire safety managers and firefighting activities carried out by fire brigades.

[0046] The fire extinguishing device according to this embodiment includes a partitioning means, a fire extinguishing agent distribution path, and a discharge port.

[0047] A "partitioning means" is a means of physically constructing a boundary surface within a target area without altering the structure of the placement location, such as walls or windows, and is positioned at least upright. For example, when placed in a room in a building, it is a means of dividing the placement location within the room into two areas on either side of the boundary surface, and is a concept that includes partitions, dividers, or screens. Here, "boundary surface" refers to each of the surfaces located on either side of the partitioning means.

[0048] Furthermore, the "fire extinguishing agent distribution route" is a route through which the fire extinguishing agent is distributed to the partitioning means, for example, provided in at least one of the panel member and frame member that constitute the partitioning means, to distribute the fire extinguishing agent. Here, the "panel member" is a flat plate-shaped member that physically constructs a boundary surface when placed in the target area, and is a member that divides the location of the target area into two areas on both sides of the panel surface (boundary surface). The "frame member" is a member that surrounds and supports the outer edge of the panel member.

[0049] Furthermore, "discharge ports" are provided at various points along the fire extinguishing agent distribution route and discharge the supplied fire extinguishing agent to at least one side of the partitioning means. For example, in the event of a fire, surface discharge is performed in which the fire extinguishing agent is discharged from multiple discharge ports provided at various points on the interface of the partitioning means. Here, "surface discharge" means that the fire extinguishing agent is discharged over a wide area of ​​the interface by having multiple discharge ports (discharge points) arranged at various points on the interface, that is, by discharging the fire extinguishing agent from discharge ports placed at various points on the interface. In addition to surface discharge, there are also point discharge and line discharge. "Point discharge" means that the fire extinguishing agent is discharged from a single point because there is one discharge port (discharge point) at one location (location), and "line discharge" means that the fire extinguishing agent is discharged in a line from multiple discharge ports arranged in a straight line.

[0050] Furthermore, fire extinguishing equipment includes cases where it is used individually and cases where it is used in combination. Here, "combining fire extinguishing equipment" means connecting the partitioning means that make up multiple fire extinguishing equipment to form a predetermined partitioned area, for example, within a target area.

[0051] Furthermore, "fire extinguishing equipment" refers to equipment that suppresses and extinguishes fires using fire extinguishing devices. This concept includes, for example, equipment that activates fire extinguishing devices through human firefighting efforts, and equipment that automatically activates fire extinguishing devices upon detection of a fire by a fire detection system with a detector connected to a receiver.

[0052] A fire extinguishing system using fire extinguishing equipment is equipped with fire extinguishing agent piping and a fire extinguishing agent supply source. Here, "fire extinguishing agent piping" refers to piping that supplies fire extinguishing agent to the fire extinguishing equipment, and is a concept that includes, for example, piping and hoses that supply fire extinguishing water, liquid fire extinguishing agent, powder fire extinguishing agent, etc. to the fire extinguishing equipment. Furthermore, "fire extinguishing agent supply source" refers to the source that supplies fire extinguishing agent to the fire extinguishing agent piping, and is a concept that includes, for example, water piping that supplies tap water, pressurized water supply equipment equipped with a pump that supplies fire extinguishing water, elevated water tanks, and fire extinguishing agent supply equipment such as fire extinguishers.

[0053] The following explanation describes the case where the "target area" is a "room in a building," the "partitioning means" is a "partition," and the "fire extinguishing agent supply source" is a "water pipe" and / or a "fire extinguisher."

[0054] [Specific details of the embodiment] Next, the specific details of the embodiment will be described. The details will be explained in the following sections. a. Fire extinguishers b. Fire extinguishing equipment with the fire extinguishing agent discharge pipe positioned vertically. c. Overview of fire extinguishing equipment d. Fire extinguishing systems using water supply piping e. Fire extinguishing equipment with connected fire extinguishers f. Fire extinguishing system combining fire extinguishers and water pipes g. Connected fire extinguishers h. A connected fire extinguishing system that switches the fire extinguishing agent distribution route using a three-way switching valve. i. Fire extinguishing equipment when partitioned compartments are formed j. Portable fire extinguishers k. Fire extinguishing equipment with a discharge port located on the frame member. l. Variations of the present invention

[0055] [a. Fire extinguishers] First, the embodiment of the fire extinguishing device will be described in more detail. As shown in Figure 1, the fire extinguishing device 10 is a device that suppresses and extinguishes fires by spraying or releasing a fire extinguishing agent. For example, it can be placed in any location requiring a partition in a room of a building such as an office building, in an upright position on the floor, without altering the structure and structural surfaces of walls, ceilings, etc. The configuration and structure of this fire extinguishing device 10 are arbitrary, but for example, it may be equipped with a partitioning means, a fire extinguishing agent distribution path, and a discharge port. For example, it may be equipped with a partition 12 as a partitioning means. In the following description, the horizontal direction of the partition 12 in the fire extinguishing device 10 in the upright position shown in Figure 1 will be referred to as the left-right direction, the vertical direction as the up-down direction, and the depth direction as the thickness direction.

[0056] (partition) The partition 12 comprises a panel member 14, a frame member, and a base 15. The panel member 14 forms a flat boundary surface, dividing the placement area for the fire extinguishing equipment 10 into two regions on either side of the boundary surface. The frame member has an arbitrary configuration and structure, but for example it consists of an upper frame 16a, middle frames 16b, 16c, and a lower frame 16d, surrounding and supporting the outer edge of the panel member 14. The base 15 allows the partition 12 to be erected on the floor surface without altering structural surfaces such as walls or ceilings, and is attached, for example, to the lower ends of the middle frames 16b, 16c.

[0057] The vertical and horizontal dimensions of the panel member 14 are arbitrary, for example, 900mm wide x 1200mm high, 900mm wide x 1600mm high, 900mm wide x 2100mm high, 900mm wide x 2500mm high, etc. The panel member 14 is a blind type that does not allow viewing to the other side, but other types, such as those with windows made of frosted glass in some parts, are also included and are optional.

[0058] More specifically, as shown in Figure 3, for example, the partition 12 has an upper frame 16a, middle frames 16b, 16c, and lower frame 16d that form a frame around the panel member 14, which are fixed by bolts 31, for example. Also, as shown in Figure 4(B), the panel member 14 is fixed in the thickness direction by adhesive or the like with spacers 33 interposed at the four corners between the first panel 30 and the second panel 32, forming an internal space between the first panel 30 and the second panel 32.

[0059] (Distribution routes for fire extinguishing agents) Inside the panel member 14 of the partition 12, a fire extinguishing agent distribution path 18, indicated by a dotted line, is provided. This fire extinguishing agent distribution path 18 is a path for distributing the fire extinguishing agent through the panel member 14. Its configuration and structure are arbitrary, but for example, it may be arranged in a ladder shape with four steps in the vertical direction (height direction). The first step, which is the top step, is a straight distribution path, while discharge ports 22 are arranged in the second to fourth steps, for example, at seven locations each. Fire extinguishing agent supply ports 24a and 24b are located on the lower side ends of the fire extinguishing agent distribution path 18, via inner frames 16b and 16c, on the outside of the left and right side end surfaces.

[0060] (Fire extinguishing agent discharge pipe) In the second to fourth stages of the fire extinguishing agent distribution path 18, where the discharge ports 22 are located, fire extinguishing agent discharge pipes 20 are positioned. The fire extinguishing agent discharge pipes 20 constitute a part of the fire extinguishing agent distribution path 18, and for example, the fire extinguishing agent discharge pipes 20 have multiple discharge ports 22 arranged in a straight line along the outer circumference.

[0061] Here, by arranging fire extinguishing agent discharge pipes 20 at each step of the ladder-shaped fire extinguishing agent distribution path 18, the rows of discharge ports arranged horizontally are treated as a single discharge port row element, and three rows of these discharge port row elements are arranged from the second to the fourth step to form the overall discharge port row.

[0062] Fire extinguishing agent distribution paths 18 are connected to both ends of the fire extinguishing agent discharge pipe 20, so that the fire extinguishing agent is supplied from both ends. This makes it possible to make the pressure of the fire extinguishing agent supplied to multiple discharge ports 22 in the same row approximately uniform, and to standardize the discharge pattern (angle distribution) and discharge amount within the same row.

[0063] As shown in Figure 5, the fire extinguishing agent discharge pipe 20 has a pipe body 34, with both ends of the pipe body 34 closed to provide pipe connection ports 38, and multiple nozzle members 36 are screwed in and fixed in a straight line along the axial direction of the outer circumference of the pipe body 34. The nozzle members 36 have communication holes that communicate with the inside of the pipe body 34, and the openings of the communication holes form multiple discharge ports 22.

[0064] Here, the diameter of the discharge port 22 provided in the fire extinguishing agent discharge pipe 20 is set to, for example, a diameter of about 3 to 4 millimeters. A diameter of about 3 to 4 millimeters corresponds to the diameter of one of the multiple discharge holes formed in a shower head that uses tap water. As a result, a discharge pattern of tap water equivalent to one of the holes in a shower head is obtained from the discharge port 22, and by discharging this discharge pattern from the discharge ports 22 at various locations on the panel surface (boundary surface) on one side of the partition 12, a surface discharge is achieved overall.

[0065] Furthermore, if a straight through-hole is provided in the nozzle member 36, the discharge pattern of the discharge port 22 will be relatively narrow-angled, and if the opening of the communication hole is widened in a conical shape, the discharge pattern will be wide-angled, and the opening shape will be appropriately chosen according to the required discharge pattern. It is also acceptable to mix discharge ports 22 with mutually different opening shapes.

[0066] In this embodiment, the central axis of the nozzle member 36 (the dashed line in Figure 5(C)) is perpendicular to the panel surface, but this is not limited to this. For example, the directionality of the fire extinguishing agent discharge can be adjusted by adjusting the inclination angle of the central axis with respect to the panel surface.

[0067] In the first panel 30 of Figure 4(B), a through-hole 35 is formed corresponding to the discharge port 22 of the panel member 14 shown in Figure 3. By fitting the nozzle member 36 provided on the fire extinguishing agent discharge pipe 20 into the through-hole 35 to form the discharge port 22, the fire extinguishing agent discharge pipe 20 can be easily positioned and fixed inside the panel member 14. When the nozzle member 36 is fitted into the through-hole 35 of the first panel 30, it is desirable that the tip opening surface of the through-hole of the nozzle member 36 be flush with the panel surface so that the discharge port 22 does not protrude from the panel surface.

[0068] Fire extinguishing agent distribution paths 18 are connected to both ends of the fire extinguishing agent discharge pipe 20, which is located within the panel member 14. The connection structure in this case is arbitrary, but for example, a rubber hose, vinyl hose, preferably a reinforced rubber hose or vinyl hose with fiber braiding, can be used as the fire extinguishing agent distribution path 18, and the fire extinguishing agent distribution path 18 can be connected to both ends of the fire extinguishing agent discharge pipe 20 using a T-joint.

[0069] Alternatively, the fire extinguishing agent discharge pipe 20 and the fire extinguishing agent distribution path 18 may be prepared as a separate assembled assembly and then integrated together by placing it between the first panel 30 and the second panel 32 via a spacer 33, as shown in Figure 4(B).

[0070] [b. Fire extinguishing equipment with fire extinguishing agent discharge pipes positioned vertically] Next, an embodiment of the fire extinguishing device 10 in which the fire extinguishing agent discharge pipes 20 are arranged vertically inside the panel member 14 will be described in more detail. As shown in Figure 6, in this embodiment, the fire extinguishing device 10 (10a) has multiple fire extinguishing agent discharge pipes 20 arranged horizontally in the vertical direction inside the panel member 14 of the partition 12. The upper ends of the horizontally arranged fire extinguishing agent discharge pipes 20 are connected to a fire extinguishing agent distribution path 18 arranged along the left edge, top edge, and right edge of the panel member 14 between the fire extinguishing agent supply ports 24a and 24b.

[0071] In this case, although the fire extinguishing agent supply channels 18 are not connected to both the upper and lower ends of the fire extinguishing agent discharge pipe 20, there is almost no pressure loss due to the drop when the fire extinguishing agent is supplied from the upper end of the fire extinguishing agent discharge pipe 20. Therefore, even if only the upper end of the fire extinguishing agent discharge pipe 20 is connected, it is possible to make the discharge pressure of the multiple discharge ports 22 arranged vertically nearly uniform, and to make the discharge pattern (angle distribution) and discharge amount the same.

[0072] [c. Overview of fire extinguishing equipment] Next, an overview of the fire extinguishing system of this embodiment using the fire extinguishing device 10 will be described. This fire extinguishing system is a system that suppresses and extinguishes fires using the fire extinguishing device 10, and as an example, as shown in Figure 1, it comprises the fire extinguishing device 10, fire extinguishing agent piping 25, fire extinguishing agent supply source 26 and on / off valve 28.

[0073] For the fire extinguishing equipment 10, a fire extinguishing agent pipe 25, which is drawn out from the fire extinguishing agent supply source 26 via a pipe shut-off valve 28 that functions as a pipe opening / closing mechanism, is connected to the fire extinguishing agent supply port 24a, supplying fire extinguishing agent to the fire extinguishing agent distribution path 18 within the partition 12, and allowing the fire extinguishing agent to be discharged from the water outlets 22 provided at various locations. The fire extinguishing agent supply port 24b on the opposite side is closed. The fire extinguishing agent supply source 26 can be a water pipe, a fire extinguisher, or the like.

[0074] [d. Fire extinguishing system using water pipes] An embodiment of a fire extinguishing system using water pipes as a fire extinguishing agent supply source will be described in more detail. As shown in Figure 7, this fire extinguishing system is characterized by using water pipes 47 as a fire extinguishing agent supply source. The configuration and arrangement of this fire extinguishing system are arbitrary, but for example, it includes the aforementioned fire extinguishing device 10, fire extinguishing agent pipes 25, remote on / off valve 45, manual on / off valve 46, and water pipes 47. The fire extinguishing device 10 is placed at a desired position in the room that will be the target area 11, and one side of the panel surface (boundary surface) of the panel member 14 on which the discharge port 22 is located is facing the area to be extinguished.

[0075] In the target area 11, a fire detector 44 is installed as a fire detection device and is connected to a receiver 42. A remote shut-off valve 45 is also connected to the receiver 42. One end of a fire extinguishing agent pipe 25 is connected to one of the fire extinguishing agent supply ports 24a (see Figure 1) of the fire extinguishing device 10, and the other end of the fire extinguishing agent pipe 25 is connected to a water pipe 47 via a parallel connection of a remote shut-off valve 45 and a manual shut-off valve 46, which function as a pipe opening and closing means.

[0076] Furthermore, it is desirable that the fire extinguishing agent piping 25 be made of rigid, ordinary piping from the water piping 25 to the point where it enters the target area 11, and flexible piping, such as a pressure-resistant hose made of rubber or vinyl, within the target area 11, so as to be able to flexibly accommodate the placement and rearrangement of the partitions 12.

[0077] If a fire occurs in the target area 11, indicated by source 40, the receiver 42 receives a fire signal from the fire detector 44 and outputs a fire alarm, outputs an open control signal to the remote valve 45 to open it, supplies tap water to the fire extinguishing equipment 10, and discharges tap water from the discharge ports 22 provided at various locations on the panel surface (boundary surface) on one side of the partition 12 toward the side where the fire originated, including the fire source 40, thereby suppressing and extinguishing the fire.

[0078] On one side of the panel surface of the panel member 14 provided in the partition 12, a row of discharge ports 22 is provided, for example, with 3 ports vertically and 7 ports horizontally. Tap water is discharged from the row of discharge ports into the target area 11 as a fire extinguishing agent to suppress and extinguish the fire. At this time, the tap water is sprayed onto the target area 11 from the side. For example, the discharge distance from the discharge ports 22 arranged in three rows is greater the higher the position of the discharge ports 22, and the further it can reach, covering part or all of the area on the discharge side as the discharge range.

[0079] Furthermore, if furniture such as tables are placed within the discharge area, the discharge from the discharge port 22 of the partition 12 will reach under the tables. In addition, if it is necessary to spray water onto the ceiling, some of the uppermost discharge ports 22 may be directed upward so that the ceiling surface is wet, thereby preventing the fire from spreading.

[0080] The fire extinguishing agent, tap water, is discharged from multiple outlets 22 located at various points on the panel surface of partition 12. In this case, tap water is discharged over an area, which is different from the conventional point discharge where sprinkler heads are placed on the ceiling and the discharge point is a single point. With the same discharge volume, a wider discharge area (water spraying area) can be covered. Furthermore, because the tap water is sprayed from the side to the fire site, the fire extinguishing agent can reach hidden locations such as under tables and desks, making it possible to suppress and extinguish the fire with a smaller amount of fire extinguishing agent.

[0081] [e. Fire extinguishing equipment with connected fire extinguishers] An embodiment of a fire extinguishing system in which a fire extinguisher is connected as a source of fire extinguishing agent will be described in more detail. As shown in Figure 8, this embodiment is characterized in that a fire extinguishing agent supply device, for example a fire extinguisher 48, is used as the source of fire extinguishing agent for the fire extinguishing device 10. The configuration and arrangement of this fire extinguishing system are arbitrary, but for example, it includes a fire extinguishing device 10, fire extinguishing agent piping 25, a fire extinguisher 48, and a fire extinguisher connection part 56. The fire extinguisher 48 supplies a predetermined fire extinguishing agent, for example a powder fire extinguishing agent or an enhanced liquid fire extinguishing agent, to the fire extinguishing device 10 and discharges the fire extinguishing agent from discharge ports 22 located at various points on the panel surface on one side of the partition 12. Note that the discharge ports 22 are shown in a simplified triangular shape.

[0082] Furthermore, the fire extinguishing agent piping 25 is made of a flexible pipe, such as a pressure-resistant hose made of rubber or vinyl, allowing for flexible arrangement and rearrangement of the partitions 12 and fire extinguishers 48. The fire extinguisher 48 has the fire extinguishing agent filled in a pressurized container, and when the safety pin 52 is removed and the lever 54 is pushed down, it opens and the fire extinguishing agent is released from the hose 50.

[0083] One end of a fire extinguishing agent pipe 25 is connected to the fire extinguishing agent supply port 24a of partition 12, and the other end of the fire extinguishing agent pipe 25 is connected to the fire extinguisher nozzle 58 at the end of the hose 50 of a fire extinguisher 48 via a fire extinguisher connecting part 56. The fire extinguisher connecting part 56, which is the connecting means, consists of a fire extinguisher nozzle 58 and a fire extinguisher connection port 60, and uses a known connecting joint similar to, for example, one used to connect a hose to a water tap so that it can be attached and detached with a single touch.

[0084] In this embodiment, the fire extinguisher nozzle 58 is obtained by removing the nozzle that is originally attached to the end of the hose of the fire extinguisher 48 and attaching a separately prepared fire extinguisher nozzle 58 in advance, but the embodiment is not limited to this.

[0085] Figure 9 shows an example of a fire extinguisher connection section 56, which is equipped with a fire extinguisher nozzle 58 and a fire extinguisher connection port 60 that can be attached and detached with a single touch. The fire extinguisher nozzle 58 is provided separately at the end of the hose 50 of the fire extinguisher 48, and the fire extinguisher connection port 60 is provided at the other end of the fire extinguishing agent piping 25, allowing the hose 50 of the fire extinguisher 48 to be attached and detached from the fire extinguishing agent piping 25 with a single touch.

[0086] The fire extinguisher nozzle 58 is equipped with a nipple 62 fitted with an O-ring at its tip, and is connected and secured by inserting the nipple 62 into the opening of the fire extinguisher connection port 60. The fire extinguisher connection port 60 is equipped with a slider 64, and the connected fire extinguisher nozzle 58 can be removed by sliding the slider 64 in the direction of the arrow shown in the figure.

[0087] The fire extinguishing device 10 using the partition 12 in this embodiment has the structure shown in Figures 1 to 4, but it may also be the fire extinguishing device 10 (10a) shown in Figure 6.

[0088] Furthermore, since the fire extinguisher 48 is placed in a designated location, such as outside the room, away from the source of the fire, even if the user is unfamiliar with handling the fire extinguisher 48, they can calmly and without panicking remove the safety pin 52 of the fire extinguisher 48 and squeeze the lever 54 to open it.

[0089] Furthermore, although the discharge of the extinguishing agent from the fire extinguisher 48 is short, for example, only a few seconds, if the fire is not extinguished after the fire extinguisher 48 has been used up, the fire extinguisher nozzle 58 can be removed from the fire extinguisher connection port 60 of the fire extinguisher connection unit 56 and replaced with a previously prepared unused fire extinguisher 48 (with a separately prepared fire extinguisher nozzle 58 attached to the hose 50), thereby continuing the discharge of the extinguishing agent and enabling reliable suppression and extinguishing. Alternatively, a fire extinguisher connection unit that can connect multiple fire extinguishers 48 can be provided, or multiple fire extinguisher connection units can be provided at multiple locations on the extinguishing agent discharge pipe 20, and multiple fire extinguishers 48 can be pre-connected to the extinguishing agent discharge pipe 20, thereby continuing the discharge of the extinguishing agent without replacing a used fire extinguisher.

[0090] Furthermore, in the event of a fire in another location (where the fire extinguishing equipment 10 of this embodiment is not installed), the fire extinguisher 48 can be detached from the fire extinguishing agent piping 25 and transported to the fire site for use. This eliminates the need to increase the number of fire extinguishers installed, thereby reducing maintenance costs.

[0091] [f. Fire extinguishing system combining fire extinguishers and water pipes] An embodiment of a fire extinguishing system combining a fire extinguisher and water piping as a source of fire extinguishing agent will be described in more detail. As shown in Figure 10, this fire extinguishing system is characterized by combining a fire extinguisher 48 and water piping 47 as a source of fire extinguishing agent for a fire extinguishing device 10 placed in the target area 11. The configuration and arrangement are arbitrary, but for example, it includes a fire extinguishing device 10, fire extinguishing agent piping 25, fire extinguisher 48, fire extinguisher connection part 56, remote on / off valve 45, manual on / off valve 46, and water piping 47.

[0092] One end of the fire extinguishing agent pipe 25 is connected to the fire extinguishing agent supply port 24a of the partition 12, and the other end is connected to the water pipe 47 via a parallel-connected remote-operated valve 45 and a manual-operated valve 46, which are pipe opening and closing means for opening and closing the pipe flow path by remote control or manually.

[0093] Furthermore, a fire extinguisher 48 is connected to a pipe branched from one end of the fire extinguishing agent pipe 25 between the remote shut-off valve 45 and the manual shut-off valve 46 (point A in the figure) via a check valve 68, which serves as a backflow prevention means to prevent backflow of tap water from the fire extinguishing agent pipe 25 to the fire extinguisher 48. In addition, a fire extinguisher connecting section 56 is provided, which serves as a connecting means to detachably connect the fire extinguisher 48 to the fire extinguisher pipe 25. The fire extinguisher connecting section 56 consists of a fire extinguisher nozzle 58 and a fire extinguisher connection port 60, and has a connecting joint structure similar to that shown in Figure 9, for example.

[0094] Furthermore, a water pipe 47 is connected to the connection point (point A in the diagram) of the check valve 68 of the fire extinguishing agent pipe 25 via a gate valve 66. Between the connection point (point A in the diagram) of the gate valve 66 and the check valve 68, a remote on-off valve 45 and a manual on-off valve 46 are connected in parallel, functioning as remote and manual control valves to open and close the flow path from the water pipe 47 to the fire extinguishing agent pipe 25. The check valve 68 prevents tap water from flowing into the fire extinguisher connection part 56 when tap water is supplied from the water pipe 47 to the fire extinguishing agent pipe 25.

[0095] Furthermore, the fire extinguishing agent piping 25 is a rigid, ordinary pipe up to the point where it enters the target area 11 beyond the connection point of the check valve 68 of the fire extinguishing agent piping 25 (point A in the figure). However, within the target area 11, a flexible pressure-resistant hose made of, for example, rubber or vinyl may be used to allow for flexibility in arranging and rearranging the partitions 12.

[0096] In the target area 11, a fire detector 44 is installed as fire detection equipment and is connected to a receiver 42. A fire alarm light 43 is installed near the location of the fire extinguisher 48 and is connected to the receiver 42. A remote on / off valve 45 is also connected to the receiver 42.

[0097] The receiver 42 can be set to an automatic fire extinguishing mode and a manual fire extinguishing mode. The automatic fire extinguishing mode is set, for example, during nighttime hours, and releases fire extinguishing agent (tap water) in conjunction with the detection of a fire by the fire detector 44 (fire alarm on the receiver). The manual fire extinguishing mode is set, for example, during daytime hours, and releases fire extinguishing agent by operating the fire extinguisher 48 or the manual shut-off valve 45. In addition to switching between manual and automatic fire extinguishing modes depending on the time of day / night, the modes may also be switched depending on the presence / absence of people, or a combination of these may be used.

[0098] If the receiver 42 is set to manual fire extinguishing mode, when a fire occurs in the target area 11 where the fire extinguishing equipment 10 is placed, the receiver 42 receives a fire signal from the fire detector 44 and outputs a fire alarm. It also lights up or flashes the fire alarm light 43 located outside the room that is the target area 11 where the fire occurred.

[0099] Upon learning of the fire, those involved go to the site of the fire, and after confirming the fire, remove the safety pin 52 from the fire extinguisher 48 and push down the lever 54 to open it. This supplies the extinguishing agent from the fire extinguisher 48 to the fire extinguishing device 10, and the powder extinguishing agent is discharged from multiple discharge ports 22 located at various points on the panel surface of the partition 12 to suppress and extinguish the fire.

[0100] If the fire cannot be confirmed to be extinguished even after the extinguishing agent from the fire extinguisher 48 has been released, the manual shut-off valve 46 is opened to supply tap water to the fire extinguishing device 10, and the tap water is discharged over the surface from multiple discharge ports 22 provided at various locations on the panel surface of the partition 12 to suppress and extinguish the fire. The discharge of tap water is carried out after the fire has been suppressed by the release of the extinguishing agent from the fire extinguisher 48, and there are no time constraints on the discharge of tap water, which ensures that the fire is extinguished reliably.

[0101] On the other hand, if the receiver 42 is set to automatic fire extinguishing mode, when the receiver 42 receives a fire signal from the fire detector 44, it transmits a control signal to the remote on-off valve 45 to open it, supplying tap water to the fire extinguishing equipment 10, and discharging the tap water across the surface from multiple discharge ports 22 provided at various locations on the panel surface of the partition 12, thereby suppressing and extinguishing the fire.

[0102] Furthermore, even in automatic fire extinguishing mode, if, for example, a person who has responded to a fire report finds that the fire is not dying down, the receiver 42 will perform a predetermined operation to close the remote shut-off valve 45, for example, by deactivating the automatic fire extinguishing mode and switching to manual fire extinguishing mode. Then, the safety pin 52 of the fire extinguisher 48 will be removed and the lever 54 will be pushed down to open it, supplying the extinguishing agent from the fire extinguisher 48 to the fire extinguishing device 10, and the extinguishing agent will be discharged from the discharge ports 22 located at various points on the panel surface of the partition 12, thereby suppressing and extinguishing the fire.

[0103] In this way, after the fire extinguishing agent has been released from the fire extinguisher 48, the manual shut-off valve 46 can be opened again to switch back to the release of tap water.

[0104] [g. Connected fire extinguishers] An embodiment in which multiple fire extinguishing devices are connected will be described in more detail. As shown in Figure 11, in this embodiment, for example, partitions 12 (12-1, 12-2) of two fire extinguishing devices 10 are connected in the target area 11 using connecting fittings not shown.

[0105] The partitions 12 (12-1, 12-2) of the fire extinguishing equipment 10, which are arranged in a connected manner, have the structure shown in Figures 1 to 5 or Figure 6.

[0106] For the partitions 12 (12-1, 12-2) of the fire extinguishing equipment 10 arranged in a connected manner, the fire extinguishing agent piping 25 from the fire extinguishing agent supply source 26 is connected to the fire extinguishing agent supply port 24a of the leading partition 12-1. At the joint A between the two, the fire extinguishing agent supply port 24b of the leading partition 12-1 and the fire extinguishing agent connection port 24a of the partition 12-2 located behind (at the end) are connected using fire extinguishing agent piping such as a hose. Furthermore, the fire extinguishing agent supply port 24b of partition 12-2 is closed.

[0107] When two fire extinguishing devices 10 partitions 12 (12-1, 12-2) are connected and arranged in the target area 11 in this manner, in the event of a fire, each of the multiple partitions 12 (12-1, 12-2) will discharge fire extinguishing agent from multiple discharge ports 22 located at various points on the panel surface, thereby securing a wide discharge area overall and enabling fire suppression and extinguishing with a small amount of fire extinguishing agent discharged.

[0108] Furthermore, when three or more fire extinguishing devices 10 are arranged in a row, one of the intermediate partition devices 12 shall have its fire extinguishing agent supply port 24a connected to the fire extinguishing agent piping from the other partition device located in front of it, and the other fire extinguishing agent supply port 24b shall have its fire extinguishing agent piping connected to the other partition device located behind it.

[0109] [h. A connected fire extinguishing device that switches the fire extinguishing agent distribution route using a three-way switching valve] An embodiment of a fire extinguishing device in which the fire extinguishing agent distribution path for each of the partitions 12 of multiple fire extinguishing devices 10 is switched by a three-way switching valve will be described in more detail.

[0110] As shown in Figure 12(A), when, for example, two fire extinguishing devices 10 partitions 12(12-1, 12-2) are connected and arranged in the target area 11, three-way switching valves 90a, 90b are provided on the side of the fire extinguishing agent supply ports 24a, 24b of each panel member 14 of the partitions 12(12-1, 2-2).

[0111] The three-way switching valves 90a and 90b have three ports a, b, and c, and allow switching operations to connect ports a and b, ports b and d, or ports ac. In addition, with the installation of the three-way switching valves 90a and 90b, a new bypass distribution route 19 has been provided that connects the fire extinguishing agent supply ports 24a and 24b in the lateral direction (left and right direction) via the three-way switching valves 90a and 90b.

[0112] When spraying fire extinguishing agent from both connected partitions 12-1 and 12-2, the three-way switching valves 90a and 90b installed in partitions 12 (12-1, 12-2) are switched as shown in Figures 12(B) to (D).

[0113] As shown in Figure 12(B), the three-way switching valve 90a on the side of the fire extinguishing agent supply port 24a to which the fire extinguishing agent piping 25 of partition 12-1 is connected communicates between ports a and b, and the fire extinguishing agent that flows in from the fire extinguishing agent piping 25 through the fire extinguishing agent supply port 24a flows out to the fire extinguishing agent distribution path 18-1 located above.

[0114] Furthermore, as shown in Figure 12(C), the three-way switching valve 90b on the fire extinguishing agent supply port 24b side of partition 12-1 connects ports b and c, and the fire extinguishing agent that flows in from the fire extinguishing agent supply channel 18-1 located above flows out to the next partition 12-2 side via the fire extinguishing agent supply port 24b.

[0115] Furthermore, the three-way switching valve 90a on the side of the fire extinguishing agent supply port 24a of the second partition 12-2, to which the fire extinguishing agent supply port 24a of partition 12-1 is connected, communicates ports a and b, as shown in Figure 12(D), and allows the fire extinguishing agent that has flowed in from partition 12-1 through the fire extinguishing agent supply port 24a to flow out to the fire extinguishing agent distribution path 18-2 located above.

[0116] Furthermore, the three-way switching valve 90b on the fire extinguishing agent supply port 24b side of partition 12-2 closes port b by connecting ports a and c, as shown in Figure 12(E), thereby closing the flow path of the fire extinguishing agent supply channel 18-2 located above to the fire extinguishing agent supply port 24b.

[0117] When spraying fire extinguishing agent only from the first partition 12-1, the three-way switching valve 90a on the fire extinguishing agent supply port 24a side is switched to a position that connects ports a and b, as shown in Figure 12(B), and the three-way switching valve 90b on the fire extinguishing agent supply port 24b side is switched to a position that connects ports a and closes port c, as shown in Figure 12(E). As a result, fire extinguishing agent is supplied and sprayed only through the fire extinguishing agent distribution path 18-1 of partition 12-1, and no fire extinguishing agent is supplied to the second partition 12-2.

[0118] When spraying fire extinguishing agent only from the second partition 12-2, the three-way switching valves 90a and 90b on the fire extinguishing agent supply ports 24a and 24b of the first partition 12-1 are switched to a position that connects ports ac and closes port b, as shown in Figure 12(E), and the fire extinguishing agent supplied from the fire extinguishing agent piping 25 is bypassed by the bypass distribution path 19 of partition 12-1 and supplied to the next partition 12-2.

[0119] The three-way switching valve 90a on the fire extinguishing agent supply port 24a side of partition 12-2 is switched to a position that connects ports a and b, as shown in Figure 12(D). The three-way switching valve 90b on the fire extinguishing agent supply port 24b side is switched to a position that connects ports a and c and closes port b, as shown in Figure 12(E). This allows fire extinguishing agent to be supplied to partition 12-2 via partition 12-1, and the fire extinguishing agent to be sprayed only from partition 12-2.

[0120] [i. Fire extinguishing equipment that forms partitioned compartments] An embodiment of a fire extinguishing device when multiple partitions are connected to form a partitioned area within a target area will be described in more detail. As shown in Figure 13, suppose that multiple partitions 12 (12-1 to 12-11) are connected and arranged in a target area 11, for example, to form a rectangle, and a door panel 78 is placed at a predetermined position to form a partitioned area 80 that can be used, for example, as a conference room or reception room. In this case, at least one of the partitions 12 (12-1 to 12-11) forming the partitioned area 80, for example partition 12 (12-2), is the fire extinguishing device 10 (10a) shown in Figures 1 to 5 or Figure 6.

[0121] Therefore, if a fire occurs in a partitioned compartment 80 separated by partitions 12 (12-1 to 12-11), the fire extinguishing agent can be discharged into the partitioned compartment 80 from partition 12 (12-2), which is provided as a fire extinguishing device 10 (10a), thereby suppressing and extinguishing the fire.

[0122] Furthermore, in the target area 11 where sprinkler heads are installed, if no sprinkler heads are installed on the ceiling surface of the partitioned section 80 separated by partitions 12 (12-1 to 12-11), the water discharged from the sprinkler heads installed outside the partitioned section 80 will be blocked by partitions 12 (12-1 to 12-11) and will not reach the area. However, one of the partitions 12 (12-2) functions as a fire extinguishing device 10, ensuring that a fire occurring in the partitioned section 80 without a sprinkler head can be reliably suppressed and extinguished.

[0123] [j. Portable fire extinguisher] An embodiment of a portable fire extinguishing device will be described in more detail. As shown in Figure 14, the fire extinguishing device 10(10b) of this embodiment, which uses a partition 12, is equipped with casters 82 so that it can be moved and placed in the required location. Such a portable fire prevention device 10(10b) is equipped with a fire extinguishing agent supply device, such as a fire extinguisher 48, as a source of fire extinguishing agent.

[0124] The fire extinguisher 48 is detachably positioned near, for example, the lower corner of the partition 12 by a fixing band 84. The hose 50 of the fire extinguisher 48 is connected via a fire extinguisher coupling 86 to a fire extinguishing agent supply port 24c provided on the panel surface of a nearby panel member 14, enabling the supply of fire extinguishing agent to the fire extinguishing agent distribution path 18. The fire extinguisher coupling 86 has a coupling joint structure similar to that shown in Figure 9, for example.

[0125] The fire extinguishing device 10(10b) of this embodiment can be easily moved by the casters 82, and since the fire extinguisher 48 is integrated into the partition 12, it is possible to move the partition 12 to any position in the target area 11 and use it as a fire extinguishing device 10(10b).

[0126] [k. Fire extinguishing device with discharge openings located on the frame member] An embodiment of a fire extinguishing device in which discharge ports are arranged on a frame member will be described in more detail. As shown in Figure 15, the fire extinguishing device 10 (10c) of this embodiment has a structure in which frosted glass 88 is placed on the upper side of the partition 12 and a panel member 14 is placed below it. Since the panel member 14 is in a low position, multiple discharge ports 22 are arranged in a straight line horizontally on one side of the upper frame 16a, which is in a high position suitable for the discharge of the fire extinguishing agent.

[0127] More specifically, a fire extinguishing agent supply passage 18, indicated by a dotted line, is arranged inside the middle frame 16b, upper frame 16a, and middle frame 16c that cover the outside of the frosted glass 88 and panel member 14. Fire extinguishing agent supply ports 24a and 24b are provided on both sides of the lower part, and a fire extinguishing agent discharge pipe 20, which forms part of the fire extinguishing agent distribution route 18, is arranged inside the upper frame 16a, which is located at a higher position. As shown in Figure 4, the fire extinguishing agent discharge pipe 20 has multiple discharge ports 22 arranged in a straight line in the horizontal direction. Thus, the partition 12 consists only of the discharge port row elements of the upper frame 16a, where the discharge ports 22 that serve as discharge points are arranged in a straight line in the horizontal direction, and fires are suppressed and extinguished by the linear discharge of fire extinguishing agent.

[0128] In addition, in the fire extinguishing device 10(10c) of this embodiment, in addition to the discharge port 22 located on the upper frame 16a of the partition 12, multiple discharge ports may be arranged at various locations on the panel surface of the panel member 14.

[0129] [l. Modifications of the present invention] Modifications of the fire extinguishing device and fire extinguishing system according to the present invention will be described in more detail. In addition to the embodiments described above, the fire extinguishing device and fire extinguishing system of the present invention include the following modifications.

[0130] (Outlet arrangement) The above embodiment shows multiple discharge ports 22 arranged at various locations on one side of the panel surface (boundary surface) of the partition 12, but is not limited to this. For example, multiple discharge ports 22 may be arranged at various locations on both sides of the panel surface (boundary surface) of the partition 12.

[0131] (partition) The above embodiment uses a fire extinguishing device and fire extinguishing equipment that uses a partition that stands upright on the floor surface by a base as an example, but it is also possible to use a fire extinguishing device and fire extinguishing equipment that uses a fixed indoor partition that is fixedly placed between the floor surface and the ceiling surface without changing the indoor structure.

[0132] Furthermore, some partitions have a structure in which multiple partitions are rotatably connected. In this case, the structure of a fire extinguisher may be provided on all partition devices, or on some of the partitions.

[0133] (Partition or screen) The above embodiment uses a fire extinguishing device that uses a partition as a partitioning means as an example, but is not limited to this. For example, a fire extinguishing device that uses a room divider or screen may also be used. When a room divider or screen is used, similar to the partition in the above embodiment, a fire extinguishing agent distribution path and multiple discharge ports are provided in the room divider or screen, and the fire extinguishing agent can be discharged over the surface from multiple discharge ports provided at various points on the dividing surface of the room divider or the screen surface of the screen to suppress and extinguish the fire.

[0134] Furthermore, the partitioning means is arbitrary and does not have to be a partition, divider, or screen. As long as it physically constructs a boundary surface while being placed in the target area without changing the structure of the target area, the fire extinguishing device of this embodiment can be realized in the same way.

[0135] (others) Furthermore, the present invention includes appropriate modifications that do not impair its purpose and advantages, and is not limited by the numerical values ​​shown in the above embodiments. [Explanation of Symbols]
