Description

[0001]
[Industrial applications]
The present invention relates to a structure of an oil stove guard for tent heating for preventing an oil stove fire from a tent collapse accident.
[0002]
[Prior art]
For an open-type oil stove used at home, a stove guard that guards the front and side of the oil stove or the entire circumferential direction of the oil stove is known. The guard prevents children from approaching the oil stove indiscriminately, and can prevent accidents such as burns caused by the heat of the oil stove or falling over the oil stove.
[0003]
This guard covers the front and side directions in a U-shape for the reflective oil stove used near the wall in the room, and the back uses the wall inside the room or is used in the center of the room Some convection type oil stoves cover four directions: front, rear, left and right. The stove guard is formed so as to be disassembled or foldable, and can be self-standing by fixing each corner at a right angle during use.
[0004]
In this way, stove guards are used in homes to prevent children from touching the oil stove, but in places where people enter and exit, the stove guard should not be hit by people and cause the oil stove to fall. When using an oil stove as heating in a temporary tent, which is an extension of this establishment, it is also desirable to use a stove guard that also covers four directions.
[0005]
[Problems to be solved by the invention]
Temporary tents installed in cold regions cannot be eliminated by heating means, but they bring in oil stoves for heating. A tent installed in a cold region where heating is required has strength enough to withstand a certain amount of strong wind and withstand some snowfall.
[0006]
However, it is not always the case that the weather changes suddenly after the tent is set up and a large amount of snow falls overnight, and it must always be possible. Originally, the use of oil stoves should be banned in such tents, but as a practical matter, there are no cheap heaters to replace, and after all, safety is left to the user, so use with care. That is the reality.
[0007]
In addition, even when the actual amount of snow meets the durability of the tent, if the snow contains a large amount of moisture, the weight of the tent may fall unexpectedly, causing the tent to collapse. The rope supporting the tent may break and the tent may collapse, and if such an accident occurs while using an oil stove, it will result in a fire accident, so not only will the safety be left to the user, but also some kind of response It is necessary to devise ways to minimize damage.
[0008]
[Means for Solving the Problems]
The present invention relates to a proposal for securing safety while using a common tent and an oil stove, and a wire guard B for an open oil stove A, wherein the guard B is an oil stove. A side guard 2 is erected from the periphery of the mounting table 1 on which A is placed, and an opening 2a for operating the oil stove is formed in a part of the side guard 2, and the side guard 2 is The upper guard 3 is formed to be taller than the upper end, and covers the entire upper opening of the guard B formed at the upper end of the side guard 2, and the mounting table is hard to receive radiant heat from the burner body 4 of the oil stove A. The tent collapse sensor 5 is provided on the side guard 2 close to 1 and an alarm sound generator 6 which is activated by the output of the tent collapse sensor 5 is attached. The oil stove burning in the tent C where the alarm sound generator 6 collapses A's By informing the resident is immediately that as to lean taken up in fire fighting.
[0009]
Further, the tent collapse sensor 5 is constituted by a sensor for detecting combustion gas or combustion heat in a space secured by the stove guard B, and the tent collapse sensor 5 is not detected in the fired oil stove A. It enables operation.
[0010]
Some commercially available oil stoves are equipped with an anti-seismic fire extinguishing system, and some of them are extinguished by a signal from a seismic switch. According to the present invention, a safety switch 7 which is operated by the output of the tent collapse sensor 5 and switches contacts when an abnormality occurs is provided. The safety switch 7 is provided with an external connection terminal 8 connected to an automatic fire extinguishing circuit of the oil stove A. Is configured to output an emergency fire extinguishing start signal for the oil stove A, thereby improving safety.
[0011]
[Action]
Although it is possible to increase the strength of a temporary tent C as in a general building, it is inevitable that the weight of the materials used will increase, and the portability will be significantly degraded, and the cost will increase significantly. become. The stove guard B used in the tent C of the present invention is provided not only in four directions on the side but also on the mounting table 1 connected to the side guard 2 and the upper guard 3 covering the open part above the side guard 2. The hot stove can now be completely protected even if the tent C collapses.
[0012]
In addition, a tent collapse sensor 5 for detecting combustion gas or combustion heat is provided below the side guard near the table 1, and an alarm sound generator 6 is activated by the output of the tent collapse sensor 5, so that the tent C should be When collapsed, the narrow space protected by Guard B is filled with carbon dioxide or carbon monoxide gas, which is a combustion gas, unlike normal use, and the temperature of the narrow space rises rapidly. In this case, the collapse of the tent C can be detected by a gas sensor or a temperature sensor that does not operate at all, and the presence of a burning oil stove is notified by an alarm sound.
[0013]
Further, if the oil stove A extinguishes due to the shock when the tent C collapses, safety can be ensured only by guarding around the oil stove A. In this case, the tent collapse sensor 5 of the present invention operates. Since no danger is foreseen, the priority of cleaning up after the collapse can be delayed.
[0014]
【Example】
The present invention will be described with reference to the embodiment shown in the drawings. A is an open-type oil stove that discharges combustion gas into a room, B is a stove guard disposed around the oil stove A, and C is a temporary tent requiring heating. The oil stove A used in the tent C is set and used in the stove guard B of the present invention.
[0015]
Reference numeral 1 denotes a mounting table on which the open oil stove A is placed, 2 denotes a side guard standing upright from the periphery of the mounting table 1 and is positioned all around the open oil stove A, and 2a is formed on a part of the side guard 2. It is an opening for operating the oil stove A, and the side guard 2 is formed by crossing wires and fixed by welding or the like. At this time, when the distance between the wires is large and the oil stove A can be directly operated, the opening 2a is formed at the distance between the wires.
[0016]
When the interval between the wires is small, the operation of the oil stove A cannot be performed. Therefore, the opening 2a may be formed by notching a portion of the wires and making a large interval. When the opening 2a is large, a frame is separately formed with the wires. Then, a lid for the opening 2a is formed, and the lid is opened and closed to operate the oil stove.
[0017]
The mounting table 1 may be formed of a single flat metal plate or the like, but in the embodiment shown in the figure, the mounting table 2 is formed by intersecting and combining elongated metal plates in order to reduce the volume and weight during storage. Then, the end of the elongated metal plate is bent upward and connected to the side guard 2. At this time, a step 1a for receiving the side guard 2 is provided at the end of the elongated metal plate, and the wire of the side guard 2 placed on the step 1a is clamped and fixed by the fixing plate 1b. 1 and the side guard 2 are separated.
[0018]
The side guard 2 of the embodiment is formed by two U-shaped frames composed of a front part and a part of the side part, and a back part and a part of the side part, and the end of the side part is a plate-like connecting plate 2b. , And is clamped and fixed by the connection fixing plate 2c.
[0019]
Reference numeral 3 denotes an upper guard made of a wire that covers the entire upper opening of the guard B formed at the upper end of the side guard 2. Reference numeral 3 a denotes a rotation bearing formed at a connecting portion between the upper guard 3 and the side guard 2. Is a locking portion located on the side guard 2 opposite to the rotary bearing 3a. The side guard 2 is taller than the oil stove A installed in the stove guard B, and the oil stove A A certain space is formed between the upper guard 3 and the upper guard 3.
[0020]
The upper guard 3 can be opened and closed with the pivot bearing 3a as a fulcrum by lifting the locking portion 3b side. With the upper guard 3 opened, the oil stove A is installed in the stove guard B and used. Sometimes, the upper guard 3 is returned, and the locking portion 3b is locked and fixed to a part of the connecting plate 2b.
[0021]
Reference numeral 4 denotes a burner main body of the open type oil stove A. In the case of the convection type core vertical oil stove provided with an oil tank at a lower portion shown in the embodiment, the upper flame tube of the oil stove A forms the burner main body 4. Further, in a reflection-type up-and-down petroleum stove (not shown), a combustion tube that glows red forms the burner main body 4. Reference numeral 5 denotes a tent collapse sensor attached to the side guard 2 near the mounting table 1 which is hardly susceptible to radiant heat from the oil stove A burner body 4. is there.
[0022]
If the tent C collapses due to any accident while the oil stove A is installed in the stove guard B and is used in the tent C, the tent C is received by the upper guard 3 of the stove guard B and directly. The material of tent C no longer touches oil stove A. For this reason, even if the tent C collapses, the minimum space is secured by the stove guard B, and the material of the tent C of the oil stove A does not immediately ignite and burn.
[0023]
Further, the tent collapse sensor 5 of the present invention comprises a carbon dioxide detector, a carbon monoxide detector and an oxygen sensor for detecting combustion gas, and the space in which the oil stove A is placed due to the collapse of the tent C becomes extremely large. If the combustion gas exhausted from the oil stove A, which continues to burn, is full because of the narrowing, carbon dioxide gas increases, oxygen becomes insufficient, and incomplete combustion occurs to generate carbon monoxide. Then, the tent C can be detected to be collapsed by directly or indirectly detecting the increase of the combustion gas by the tent collapse sensor 5 using a gas sensor. The vessel 6 was able to indicate that there was a burning oil stove A in the collapsed tent C.
[0024]
Further, the tent collapse sensor 5 of the present invention may be constituted by a temperature sensor for detecting a room temperature. When the space in which the oil stove A is placed becomes extremely narrow due to the collapse of the tent C, the oil stove A that continues burning is used. Since the ambient temperature rises rapidly, the tent C can be detected to be collapsed by detecting the temperature rise with the tent collapse sensor 5 using a thermistor, and the alarm sound generator 6 that sounds upon receiving the output of the tent collapse sensor 5 It was possible to inform that a burning oil stove A was in a collapsed tent C.
[0025]
Therefore, if an alarm is issued during the work of cleaning up the collapsed tent C, it is known that the oil stove A is burning and a fire may occur, and the fire extinguishing work of the oil stove A is performed with priority. The occurrence of fire was prevented beforehand.
[0026]
On the other hand, open-type oil stoves on the market are provided with an automatic anti-seismic fire extinguisher according to JIS standards, and use a switch that switches contacts when a predetermined acceleration is applied as a sensor of this fire extinguisher. There is. That is, in the electric circuit shown in the embodiment of FIG. 3, 9 is an ignition switch, 10 is an igniter, and when the ignition switch 9 is closed while the burner main body 4 is in a combustible state, the igniter 10 operates to burn. Start.
[0027]
Reference numeral 11 denotes a seismic switch constituted by an acceleration sensor, and reference numeral 12 denotes a fire extinguishing means. When the seismic switch 11 detects the occurrence of an earthquake, the fire extinguishing means 12 operates to automatically extinguish the oil stove B.
[0028]
Reference numeral 13 denotes a dry battery power supply for the tent collapse sensor 5 and the alarm sound generator 6, etc., 14 denotes a safety device driving unit including a relay circuit operated by the output of the tent collapse sensor 5, and 7 denotes a switch by the output of the safety device driving unit 14. The safety switch 8 is composed of relay contacts, and 8 is an external connection terminal for the safety switch 7. In the oil stove A using the automatic fire extinguishing means 12 having the seismic switch 11 shown in the figure, the external connection terminal 8 is used. Thus, the mounting terminals of the safety switch 7 and the seismic switch 11 can be connected in parallel.
[0029]
For this reason, when the tent C collapses due to some trouble, if the oil stove A in the narrow space protected by the stove guard B continues to burn, the tent collapse sensor 5 is activated and the safety switch 7 is switched. Since the fire extinguishing means 12 of the oil stove A can be operated and the oil stove A automatically extinguishes, there is no need to perform the fire extinguishing operation of the oil stove A after the tent C collapses, and other operations are given priority. Could do it.
[0030]
In the mounting position of the tent collapse sensor 5 according to the present invention, an abnormality in the combustion gas cannot be detected in this portion in a normal combustion state due to the natural ventilation rate of the tent C, and the radiant heat of the burner main body 4 is not easily received. The temperature of the part does not rise abnormally. However, when used abnormally, such as when continuously burning the open-type oil stove A for a long time, the combustion gas may become abnormal due to lack of oxygen, or the temperature in the tent C may rise to an abnormally high temperature. Since the tent collapse sensor 5 operates even in such abnormal use, the user can be notified of the abnormality by the alarm sound generator 6.
[0031]
【The invention's effect】
As described above, according to the present invention, the stove guard B of the present invention is used in the tent C without changing the structure of the tent C or the structure of the open-type oil stove A to be used. B has a table 1 connected to the side guard 2 as well as the four directions on the side, and an upper guard 3 covering an open portion is mounted on the upper side of the side guard 2, so that the tent C collapses. Even so, the hot oil stove A is completely protected by the stove guard B, so that the material of the collapsed tent C does not directly touch the oil stove A, so that no fire accident occurs immediately.
[0032]
Even if the tent C collapses, the stove guard B secures a minimum space around the oil stove A, so that no fire occurs immediately. However, if the combustion is continued in this narrow space, the combustion gas such as carbon dioxide gas or carbon monoxide gas quickly fills up, and the temperature of the narrow space rises rapidly, resulting in a fire accident.
[0033]
In the present invention, the tent collapse sensor 5 is provided below the side guard 2 close to the table 1 of the stove guard B, and the abnormality of the combustion gas or the temperature abnormality generated by the oil stove A in the collapsed tent C is detected. The alarm sound generator 6 is activated by the tent collapse sensor 5 which does not operate at all when the use of the fire alarm. The alarm sound indicates the presence of the burning oil stove A, and the fire extinguishing operation prevents the occurrence of a fire accident. Is now available.
[0034]
On the other hand, an ordinary oil stove A is equipped with an anti-seismic automatic fire extinguishing system, and when the tent C collapses, the oil stove A can be extinguished. Just by doing so, safety can be ensured. Since the tent collapse sensor 5 of the present invention does not operate in such a case and does not generate an alarm sound, there is no need to confirm fire extinguishing of the oil stove A at the beginning after the collapse, and the tent C collapses. Of the many later cleanups, prioritizing other necessary work has made it possible to smoothly clean up the tent C after the collapse.
[0035]
Some of the automatic anti-seismic fire extinguishers provided in the oil stove A extinguish a fire using a seismic switch that opens and closes an electric circuit. Since the safety switch 7 is provided, if the automatic fire extinguishing circuit of the oil stove A is operated by using the external connection terminal 8, the oil stove A can be surely automatically extinguished when the tent C collapses by the function of the tent collapse sensor 5. And increased safety.
[0036]
Further, if the tent collapse sensor 5 of the present invention is a sensor for detecting abnormal temperature, it operates even when the inside of the tent C becomes high after continuous operation for a long time, so that unnecessary heating for the user can be stopped. When the tent collapse sensor 5 detects the combustion gas, it also operates when abnormal combustion occurs due to mishandling of the oil combustor or the like. It is possible to extinguish fires and evacuate in case of emergency, thereby improving safety and making it easier to use.
