Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fire extinguisher for each room of a dwelling unit such as a detached house in which large and small rooms are mixed.

[0002]

2. Description of the Related Art Conventionally, as an automatic fire extinguishing device for dwelling units, a fire extinguishing nozzle is installed in each room, and conduits connected to these fire extinguishing nozzles are connected to each other to store a fire extinguishing agent. Many are connected to containers. A fire detecting means is provided integrally with the fire extinguishing nozzle, and the inside of each conduit is filled with a pre-pressurized extinguishing agent. When a fire occurs in any room, the fire detecting means provided in the fire extinguishing nozzle of that room is provided. There is a structure in which a fire extinguishing nozzle is opened by means to inject a fire extinguishing agent.

[0003] In such a conventional automatic fire extinguishing system, all the fire extinguishing agent in the extinguishing agent storage container connected in advance to the room where a fire has occurred is discharged. However, depending on the size of the room, the amount of medicine in the container may be insufficient or excessive, and there is a problem that fire extinguishing is insufficient or the medicine is wasted.

[0004]

According to the present invention, an examination has been made in view of the above problems, and as a result, an inexpensive automatic fire extinguishing system for a plurality of compartments capable of discharging an appropriate amount of fire extinguishing agent to rooms of different sizes has been developed. It was done. That is, according to the present invention, a fire extinguishing agent is opened by a fire signal, and a plurality of fire extinguishing agent storage containers having an operating part for sending out an extinguishing agent inside are installed in a conduit connected to the jet opening, and these conduits are connected to each other. The fire extinguishing agent that communicates with the fire extinguishing nozzles that open the injection port for the extinguishing agent by the heat of the fire installed in each of the multiple fire extinguishing compartments, and opens the chemical ejection opening according to the size of each fire extinguishing compartment. This is characterized in that the number of storage containers is changed, and it is effective to increase or decrease the number of fire extinguishing nozzles to be installed, depending on the size of the fire extinguishing target compartment.

[0005]

Next, an embodiment of the present invention will be described. FIG.
As shown in the figure, the present invention device was applied to a dwelling unit including two fire extinguishing sections having different sizes, a large room (1) and a small room (2). In each of the rooms (1) and (2), a fire extinguishing nozzle with a fire detector that emits a fire signal when the jet of the fire extinguishing agent is closed with a lid plate fixed with low melting point metal and the lid plate comes off due to fire heat. (3a) and (3b) are provided. These fire extinguishing nozzles with detectors (3a) and (3b) have a conduit (4) for guiding the extinguishing agent
These conduits (4) are connected to each other to form a single line, and the other end of each of the operating portions (6) (6) of the two outdoor fire extinguishing agent storage containers (5) (5 ′) is connected. ')
Branched and connected. As a fire-extinguishing nozzle with a sensor having such a structure, those disclosed in Japanese Patent Application Laid-Open No. 6-205852 and Japanese Patent Application No. 7-316013 can be used.

The operating parts (6) and (6 ') are electrically connected to the respective fire detectors provided on the fire extinguishing nozzle (3) via a control panel (7). When a fire occurs in 2), the lid plate of the fire extinguishing nozzle with detector (3a) in the room comes off and the fire is reported to the control panel (7). Then, a signal for executing the operation of opening the medicine ejection port of the storage container (5) is sent from the control panel (7) to the operating part (6) of the one medicine storage container (5), and the pressure is applied from the storage container (5). The extinguished chemical is discharged through the conduit (4) to the small room (2) to extinguish the fire. At the same time, an alarm can be issued by the control panel (7). At this time, the amount of the extinguishing agent released is one storage container (5), and the storage container (5)
By setting the size of to an appropriate value, it is possible to select an optimal amount of medicine for extinguishing the fire in the small room (2).

For example, when a fire occurs in the large room (1), a fire signal is sent from the fire extinguishing nozzle (3b) in that room to the control panel (7), and both storage containers (2) are sent from the control panel (7). 5) Since an operation signal is issued to the operation section (6) (6 ′) of (5 ′), the fire extinguishing agent in the two storage containers (5) (5 ′) is discharged from the fire extinguishing nozzle (3b) into the large room. It will be released to (1).

According to the configuration of the present invention, a larger fire extinguishing target can be extinguished more quickly with a larger amount of fire extinguishing agent according to the size of the fire extinguishing target, and a smaller fire extinguishing target can be obtained. The compartment can be extinguished with a small amount of extinguishing agent without waste.

Further, as another example of the present invention, two or more fire extinguishing nozzles with detectors are attached to the large room (1) in FIG. With this configuration, when a fire occurs in the large room (1), the lid plates of the two or more fire extinguishing nozzles with detectors come off simultaneously or with a time delay. Since each chemical injection port is opened, the fire extinguishing agent can be injected over a wider range, and more complete fire extinguishing can be performed.

In the above embodiment, there is an automatic fire extinguisher with two medicine storage containers for a dwelling unit having two large and small rooms. However, there are three large, medium and small rooms, each of a small room, a medium room and a large room. 1, 2, and 3 storage containers can be opened. Similarly, two storage containers are provided for three large, medium, and small rooms, and one storage container is opened for each of the small room, the middle room, and the large room.
And two or one, two and two.

In this embodiment, the fire extinguishing nozzle with a sensor as described above is used. However, the fire extinguishing nozzle having an opening formed by fire heat and the sensor may be provided separately.

[0012]

As described above, according to the present invention, a fire extinguishing agent in an amount corresponding to the size of a fire extinguishing agent is attached to the fire extinguishing target compartments of various sizes such as various rooms of dwelling units. Since the fire extinguishing nozzle can discharge the fire extinguishing nozzle, such an automatic fire extinguishing system for dwelling units can be provided at low cost, and the storage and use amount of the fire extinguishing agent is appropriate, and appropriate fire extinguishing can be performed at low cost.
