Description

本発明は、グリセリン水溶液等の発煙剤を使用して煙感知器の試験に用いる煙を発生させる発煙装置に関する。 The present invention relates to a smoke generator that uses a smoke agent such as an aqueous glycerin solution to generate smoke used in a smoke detector test.

従来、オフィス等の建物内には火災報知設備が設置されており、火災が発生した場合に、火災により発生した煙を煙感知器で検知して発報信号を受信機に送って火災警報を出力させ、消火、避難、消防活動を行うことができるようにしている。 Conventionally, fire alarm equipment has been installed in buildings such as offices, and when a fire breaks out, the smoke generated by the fire is detected by a smoke detector and a warning signal is sent to the receiver to issue a fire alarm. It is output so that fire extinguishing, evacuation, and firefighting activities can be carried out.

火災報知設備は、建物への設置後、定期的に点検が行われており、煙感知器については、天井面に設置された煙感知器を取外し、点検の際に持ち込んだ感度試験装置を使用して所定の煙濃度で火災発報することを確認する感度試験を行い、感度試験の済んだ煙感知器を天井面に取り付けた後に、可搬式の加煙試験器を使用して火災発報することを確認する動作試験を行っている。また、火災報知設備の施工時にも、可搬式の加煙試験器を使用して火災発報することを確認する動作試験を行っている。 The fire alarm system is inspected regularly after it is installed in the building, and for the smoke detector, the smoke detector installed on the ceiling is removed and the sensitivity test equipment brought in during the inspection is used. Then, a sensitivity test is conducted to confirm that a fire is triggered at a predetermined smoke concentration, and after mounting the smoke detector that has undergone the sensitivity test on the ceiling surface, a portable smoke tester is used to trigger a fire. We are conducting an operation test to confirm that this is done. In addition, when constructing a fire alarm system, an operation test is conducted to confirm that a fire is reported using a portable smoke tester.

このような従来の感度試験装置や加煙試験器は、スプレーにより煙状微粒子を含む試験用ガス(擬似煙)を発生させるもの(特許文献1)や、試験油を浸透させた浸透材を電気ヒータにより加熱して油煙を発生させて、この油煙を送風装置により強制的に上昇させるもの(特許文献2)、線香の煙を用いるものが提案されている。 Such conventional sensitivity test devices and smoke testers use a spray that generates test gas (pseudo-smoke) containing smoke-like fine particles (Patent Document 1) and a penetrant that has been impregnated with test oil. Proposals have been made in which oil smoke is generated by heating with a heater and the oil smoke is forcibly raised by a blower (Patent Document 2), or incense smoke is used.

しかしながら、スプレーによる加煙試験器にあっては、フロンガスを使用しているため環境負荷が大きく、また、今後は代替フロンの入手困難や価格高騰などの問題がある。代替ガスとしてLPGを使用することもできるが、LPGは可燃性であり、低温で使用できないなどの問題がある。 However, the smoke tester using a spray has a large environmental load because it uses CFC gas, and there are problems such as difficulty in obtaining CFC substitutes and soaring prices in the future. LPG can be used as an alternative gas, but there is a problem that LPG is flammable and cannot be used at a low temperature.

また、油煙式の加煙試験器にあっては、煙を放出し始めてから煙濃度が上昇して煙感知器が試験発報するまで時間がかかる問題がある。 Further, in the oil smoke type smoke tester, there is a problem that it takes time from the start of emitting smoke until the smoke concentration rises and the smoke detector issues a test report.

また、線香を用いる加煙試験器にあっては、線香のにおいが残ってしまうために試験場所によっては特に忌避される問題がある。 Further, in the smoke tester using incense sticks, there is a problem that the odor of incense sticks remains, which is particularly repelled depending on the test location.

この問題を解決するため、本願発明者等は、容器に人体に無害なグリセリン水溶液やグリコールエチレン水溶液等の発煙剤を収納し、不燃性の芯材に含浸された発煙剤をヒータにより加熱して煙を発生させる発煙装置を提案しており、容器に試験に必要な量の発煙剤を入れておくことができ、使用により発煙剤が減少した場合には補充することができ、作業効率を向上可能としている。 In order to solve this problem, the inventors of the present application store a smoke agent such as an aqueous solution of glycerin or an aqueous solution of glycolethylene, which is harmless to the human body, in a container, and heat the smoke agent impregnated in the nonflammable core material with a heater. We are proposing a smoke generator that generates smoke, and it is possible to put the amount of smoke agent required for the test in the container, and if the smoke agent decreases due to use, it can be replenished, improving work efficiency. It is possible.

しかしながら、容器に収納されたグリセリンやグリコールエチレン等の水溶液を用いた発煙剤は、水を主成分としているため、何らかの理由でカビ等の菌が混入してしまった場合、時間の経過とともに容器に入ったカビが繁殖する可能性を否定できない。ヒータの加熱により基本的にカビは死滅するが、発煙とともに空気中に耐熱性を有する菌などを放出してしまう虞れがある。 However, since the fuming agent using an aqueous solution such as glycerin or glycolethylene stored in the container contains water as the main component, if fungi such as mold are mixed in for some reason, the container will be filled with time. There is no denying the possibility that the mold that has entered will propagate. Molds are basically killed by heating the heater, but there is a risk that heat-resistant bacteria and the like will be released into the air as the smoke is emitted.

この問題を解決するためには、容器に除菌済みの発煙剤を充填するか、或いは、頻繁に発煙剤を入れ替えるといった対応が考えられるが、発煙剤の管理に手間と時間がかかり、発煙剤を使用したことの利点が損なわれる可能性がある。 In order to solve this problem, it is conceivable to fill the container with a sterilized fuming agent or replace the fuming agent frequently, but it takes time and effort to manage the fuming agent, and the fuming agent The benefits of using the can be compromised.

また、殺菌効果のある薬剤を添加する対応でも、物性の変化に伴い発生する煙の量が変化したりコストアップになってしまう虞がある。 In addition, even if a chemical having a bactericidal effect is added, the amount of smoke generated may change or the cost may increase due to changes in physical properties.

本発明は、カビを発生させることなく、グリセリン水溶液等を用いた発煙剤を容器に収納したまま使用可能とする発煙装置を提供することを目的とする。 An object of the present invention is to provide a smoke emitting device capable of using a smoke emitting agent using an aqueous solution of glycerin or the like while being stored in a container without generating mold.

(発煙装置の概要)
図1に示すように、本実施形態の発煙装置10は、発煙剤16が収納されるカップ状の透明な容器12を有し、容器12の上部開口は回路基板を用いた蓋部材14が接着固定されることで閉鎖されている。
[Smoke generator]
(Overview of smoke generator)
As shown in FIG. 1, the smoke emitting device 10 of the present embodiment has a cup-shaped transparent container 12 in which the smoking agent 16 is stored, and a lid member 14 using a circuit board is adhered to the upper opening of the container 12. It is closed by being fixed.

蓋部材14には、一対の液漏れ防止キャップ15が配置される。液漏れ防止キャップ15には紐状の芯材18の両端を通し、芯材18の先端を容器12に収納された発煙剤16に浸漬させ、毛細管現象により発煙剤16を吸い上げ、芯材18に発煙剤16を含浸させている。 A pair of liquid leakage prevention caps 15 are arranged on the lid member 14. Both ends of the string-shaped core material 18 are passed through the liquid leakage prevention cap 15, the tip of the core material 18 is immersed in the smoke generating agent 16 stored in the container 12, the smoke generating agent 16 is sucked up by the capillary phenomenon, and the core material 18 is sucked up. It is impregnated with the fuming agent 16.

芯材18としては、不燃性のガラス繊維、シリカ繊維、ステンレス撚り線等を使用する。また、発煙剤16としては、親水性を有し保水性が高い成分、例えば、グリセリン、プロピレングリコール等の成分のうち少なくとも一成分を含む人体に無害な水溶性液体が用いられる。 As the core material 18, nonflammable glass fiber, silica fiber, stainless stranded wire or the like is used. Further, as the fuming agent 16, a water-soluble liquid containing at least one component among components having hydrophilicity and high water retention, for example, glycerin, propylene glycol, etc., which is harmless to the human body is used.

The heater 20 is a metal wire such as a nichrome wire or a platinum wire. For example, a heater wire having a wire diameter of 0.2 to 0.4 mm is wound around a core material 18 in a coil shape, and the coil inner diameter is 1.0 to 3.0 mm. The coil length is 10 mm or less.

ヒータ20はコイル両端を蓋部材14に起立した一対のコイル支持ポール22にねじ24により固定して支持しており、蓋部材14の回路パターンにコイル支持ポール22を介してコイル両端が電気的に接続されている。蓋部材14の右端の端子部にはリード線28が接続され、リード線28はコネクタ30により後の説明で明らかする制御部に接続され、ヒータ20に対する通電加熱制御が行われる。 The heater 20 is supported by fixing both ends of the coil to a pair of coil support poles 22 standing upright on the lid member 14 with screws 24, and both ends of the coil are electrically connected to the circuit pattern of the lid member 14 via the coil support poles 22.

制御部の通電加熱制御によりヒータ20に通電されると、発煙剤16が含浸された芯材18が加熱され、ヒータ20の芯材18に対する接触部分が変霧器(アトマイザー)として機能し、芯材18に含浸されているグリセリン、プロピレングリコール等の成分を含む水溶性液体としての発煙剤16が気化され、煙を模した蒸気となって放出される。 Energization of the control unit When the heater 20 is energized by heating control, the core material 18 impregnated with the smoke generator 16 is heated, and the contact portion of the heater 20 with the core material 18 functions as an atomizer, and the core The fuming agent 16 as a water-soluble liquid containing components such as glycerin and propylene glycol impregnated in the material 18 is vaporized and released as vapor imitating smoke.

また、蓋部材14に支持されたヒータ20の近傍の基板上には温度検知器42が配置されており、回路パターンを介してリード線28に接続され、リード線28のコネクタ30により制御部に接続される。温度検出部42としては、サーミスタ、熱電対等の温度センサが使用される。また、温度検出部42は、蓋部材14ではなく、ヒータ20が巻かれた芯材18の部分に埋め込み又は差し込むように配置しても良い。 Further, a temperature detector 42 is arranged on a substrate near the heater 20 supported by the lid member 14, is connected to the lead wire 28 via a circuit pattern, and is connected to the control unit by the connector 30 of the lead wire 28. Be connected. As the temperature detection unit 42, a temperature sensor such as a thermistor or a thermoelectric pair is used. Further, the temperature detection unit 42 may be arranged so as to be embedded or inserted into the portion of the core material 18 around which the heater 20 is wound, instead of the lid member 14.

また、蓋部材14には発煙剤注入口キャップ26が設けられ、注射器等を使用することにより、発煙剤注入口キャップ26を介して容器12内に発煙剤16を注入して補充できるようにしている。なお、容器12の側面には、発煙剤16の量を示す目盛を設けても良い。 Further, the lid member 14 is provided with a smoke agent injection port cap 26, and by using a syringe or the like, the smoke agent 16 can be injected into the container 12 via the smoke agent injection port cap 26 to be replenished. There is. A scale indicating the amount of the fuming agent 16 may be provided on the side surface of the container 12.

(殺菌構造)
発煙装置10に設けられた容器12は架台32上に配置されており、架台32の容器12の底部に対応した位置には円形穴32aが形成されている。架台32の下には制御基板34が配置される。容器12の底部に相対した制御基板34上には、殺菌手段である紫外線発光素子36が配置されている。
(Sterilization structure)
The container 12 provided in the smoke generator 10 is arranged on the gantry 32, and a circular hole 32a is formed at a position corresponding to the bottom of the container 12 of the gantry 32. A control board 34 is arranged under the gantry 32. An ultraviolet light emitting element 36, which is a sterilizing means, is arranged on the control substrate 34 facing the bottom of the container 12.

架台32により、制御基板34の属する空間とヒータ20等が属する発煙部が属する空間が区切られており、発煙により生じた水蒸気等が制御基板34に結露しない構造となっている。 The gantry 32 separates the space to which the control board 34 belongs and the space to which the smoke emitting part to which the heater 20 and the like belong, so that water vapor and the like generated by the smoke generation do not condense on the control board 34.

周知のように、紫外線は強い殺菌作用があり、殺菌作用が最大となる波長は約260nm付近にある。紫外線発光素子36は、市販のものが使用され、例えば殺菌能力の高い波長265nmにピーク特性をもち、数十mWの光出力を得ることができ、指向特性は120°となる。 As is well known, ultraviolet rays have a strong bactericidal action, and the wavelength at which the bactericidal action is maximized is around 260 nm. As the ultraviolet light emitting element 36, a commercially available one is used. For example, it has a peak characteristic at a wavelength of 265 nm and has a high bactericidal ability, can obtain an optical output of several tens of mW, and has a directional characteristic of 120 °.

また、紫外線発光素子36からの紫外線を照射する容器12としては、紫外線の透過率の高い材料として、例えば、無アルカリガラスを用いた紫外線透過ガラスを使用し、紫外線を低損失で透過して収納している発煙剤16に照射できるようにしている。 Further, as the container 12 that irradiates the ultraviolet rays from the ultraviolet light emitting element 36, as a material having a high ultraviolet transmittance, for example, an ultraviolet transmissive glass using non-alkali glass is used, and the ultraviolet rays are transmitted and stored with low loss. It is possible to irradiate the smoking agent 16 that is being used.

本実施形態にあっては、容器12に収納された発煙剤16に対し、紫外線発光素子36から数秒程度、紫外線を照射することで、発煙剤16に入ったカビ等を殺菌することができる。 In the present embodiment, the smoke agent 16 stored in the container 12 is irradiated with ultraviolet rays from the ultraviolet light emitting element 36 for about several seconds to sterilize mold and the like contained in the smoke agent 16.

一方、紫外線を目に受けると、角膜炎や結膜炎を起こす虞があり、紫外線が人の目に入ることを避ける必要がある。 On the other hand, when exposed to ultraviolet rays, there is a risk of causing keratitis and conjunctivitis, and it is necessary to avoid the ultraviolet rays from entering the human eye.

このため本実施形態では、制御基板34に露出検出素子38として外からの可視光等に反応する受光素子を設けている。露出検出素子38が受光可能な角度に対向する範囲の少なくとも一部と露出検出素子38が検出する光の波長が透過する材質で形成されるようにするため、露出検出素子38の正面を含む領域には透明板32bが架台32にはめ込まれている。 Therefore, in the present embodiment, the control board 34 is provided with a light receiving element that reacts with visible light from the outside as an exposure detection element 38. A region including the front surface of the exposure detection element 38 so that at least a part of the range facing the angle at which the exposure detection element 38 can receive light is formed of a material through which the wavelength of the light detected by the exposure detection element 38 is transmitted. A transparent plate 32b is fitted in the gantry 32.

露出検出素子38により受光出力が得られているときは、発煙装置10は外部に露出した状態にあると判断して紫外線発光素子36の発光駆動を禁止し、露出検出素子38による受光出力が断たれたときには、発煙装置10は外部に露出していない状態にあると判断し、紫外線発光素子36の発光駆動を許容し、安全性を確保している。 When the light receiving output is obtained by the exposure detection element 38, the smoke emitting device 10 determines that the smoke emitting device 10 is exposed to the outside, prohibits the light emitting drive of the ultraviolet light emitting element 36, and cuts off the light receiving output by the exposure detecting element 38. When it hangs down, it is determined that the smoke emitting device 10 is not exposed to the outside, and the ultraviolet light emitting element 36 is allowed to emit light to ensure safety.

なお、紫外線発光素子36の配置位置は、容器12に収納した発煙剤16に対し均一に紫外線を照射できる位置であれば、適宜の位置に配置することができる。また、円形穴32aに相当する部分は紫外線を透過できれば良く、円形穴32aの代わりに透明な板をはめ込むようにして紫外線を透過しつつ力学的には容器12を支えるようにしても良い。 The ultraviolet light emitting element 36 can be arranged at an appropriate position as long as the smoke generating agent 16 stored in the container 12 can be uniformly irradiated with ultraviolet rays. Further, the portion corresponding to the circular hole 32a may be able to transmit ultraviolet rays, and instead of the circular hole 32a, a transparent plate may be fitted to transmit ultraviolet rays while mechanically supporting the container 12.

(発煙装置と制御部)
図5は発煙装置と制御部の機能構成を示したブロック図である。図5に示すように、発煙装置10に対応して設けられた制御部46は、感度試験装置100の電源スイッチ112をオン操作した場合、電源部115から定電圧電源の供給を受けて動作する。
(Smoke generator and control unit)
FIG. 5 is a block diagram showing a functional configuration of a smoke generator and a control unit. As shown in FIG. 5, the control unit 46 provided corresponding to the smoke emitting device 10 operates by receiving a constant voltage power supply from the power supply unit 115 when the power switch 112 of the sensitivity test device 100 is turned on. ..

制御部46は、ハードウェアとしてCPU、メモリ、各種の入出力ポート等を備えたコンピュータ回路等で構成され、CPUによるプログラムの実行により実現される機能として、発煙制御部48と殺菌制御部50が設けられている。 The control unit 46 is composed of a CPU, a memory, a computer circuit having various input / output ports, etc. as hardware, and the smoke generation control unit 48 and the sterilization control unit 50 are functions realized by executing a program by the CPU. It is provided.

発煙制御部48は、図2に示した感度試験装置100の操作部114により所定の試験開始操作を行ったときに起動し、所定の電圧・電流をコイルに印加して、又は温度検出部42による検出温度を所定温度に保つように発煙装置10のヒータ20を加熱制御して煙を発生させる。 The smoke generation control unit 48 is activated when a predetermined test start operation is performed by the operation unit 114 of the sensitivity test device 100 shown in FIG. 2, and a predetermined voltage / current is applied to the coil or the temperature detection unit 42. The heater 20 of the smoke generator 10 is heated and controlled to generate smoke so that the temperature detected by the above is maintained at a predetermined temperature.

殺菌制御部50は、電源スイッチ112による電源投入時、又は、電源投入後に感度試験装置100の操作部114により最初の試験開始操作を行ったときに、発煙装置10の紫外線発光素子36を数秒程度、発光駆動し、容器12に収納した発煙剤16に紫外線を照射して殺菌する制御を行う。 The sterilization control unit 50 sets the ultraviolet light emitting element 36 of the smoke emitting device 10 for about several seconds when the power is turned on by the power switch 112 or when the first test start operation is performed by the operation unit 114 of the sensitivity test device 100 after the power is turned on. , Light emission drive, and control is performed to sterilize the smoking agent 16 stored in the container 12 by irradiating it with ultraviolet rays.

また、殺菌制御部50は、発煙装置10に設けた露出検出素子38の露出検出信号に基づき、紫外線発光素子36の発光駆動を禁止する制御を行う。即ち、発煙装置10が図2に示すように、装置本体102から引き出されて外部に露出している場合には、受光素子を用いた露出検出素子38は外部からの光を受光して露出検出信号を出力しており、紫外線発光素子36の発光駆動を禁止する制御を行っている。このため電源スイッチ112による電源投入又は最初の試験開始操作が行われても、紫外線発光素子36は駆動されず、紫外線が人の目に入って炎症等を引き起こすことを確実に防止し、高い安全性が確保される。 Further, the sterilization control unit 50 controls to prohibit the light emission drive of the ultraviolet light emitting element 36 based on the exposure detection signal of the exposure detection element 38 provided in the smoke emitting device 10. That is, as shown in FIG. 2, when the smoke emitting device 10 is pulled out from the device main body 102 and exposed to the outside, the exposure detecting element 38 using the light receiving element receives the light from the outside and detects the exposure. A signal is output, and control is performed to prohibit the light emission drive of the ultraviolet light emitting element 36. Therefore, even if the power is turned on by the power switch 112 or the first test start operation is performed, the ultraviolet light emitting element 36 is not driven, and the ultraviolet rays are surely prevented from entering the human eye and causing inflammation, etc., and are highly safe. Sex is ensured.

一方、図3に示すように、発煙装置10が装置本体102内に収納されている場合には、殺菌制御部50は、受光素子を用いた露出検出素子38に対する光の入射が遮断され、露出検出信号の出力が停止しており、紫外線発光素子36の発光駆動を許容する制御を行っている。このため電源スイッチ112による電源投入又は最初の試験開始操作が行われると、紫外線発光素子36の発光駆動が行われ、発煙が行われるタイミングの直前に容器12に収納した発煙剤16が紫外線の照射により殺菌される。 On the other hand, as shown in FIG. 3, when the smoke emitting device 10 is housed in the device main body 102, the sterilization control unit 50 blocks the light from entering the exposure detecting element 38 using the light receiving element and exposes it. The output of the detection signal is stopped, and control is performed to allow the ultraviolet light emitting element 36 to drive the light emission. Therefore, when the power is turned on by the power switch 112 or the first test start operation is performed, the ultraviolet light emitting element 36 is driven to emit light, and the smoke generating agent 16 stored in the container 12 is irradiated with ultraviolet rays immediately before the timing when the smoke is emitted. Is sterilized by.

なお、発煙装置10が露出状態にあるか否かを検出する露出検出素子38としては、図2に示した引出カバー118の開閉を検出する検出スイッチとしても良い。 The exposure detection element 38 for detecting whether or not the smoke emitting device 10 is in an exposed state may be a detection switch for detecting the opening / closing of the drawer cover 118 shown in FIG.

Smoke is flowed along the route to 220, and the smoke detector 130 is test-issued to confirm the operation.

加煙試験器200による煙感知器130の試験作業は、警戒区域の天井面に設置されている多数の煙感知器を順次試験する作業となるが、加煙試験器200に組み込まれた発煙装置10は、図1に示したように、容器12の発煙剤16をヒータ20による通電加熱で霧化して煙を発生させており、煙感知器130に対し十分な量の煙を供給して短時間で試験することができる。 The test work of the smoke detector 130 by the smoke tester 200 is a work of sequentially testing a large number of smoke detectors installed on the ceiling surface of the caution area, and the smoke generator incorporated in the smoke tester 200. As shown in FIG. 1, No. 10 atomizes the smoke generating agent 16 of the container 12 by energization heating by the heater 20 to generate smoke, and supplies a sufficient amount of smoke to the smoke detector 130 for a short period of time. Can be tested in time.

また、リモコンユニット205により最初の試験開始操作を行うと、制御部46に設けた殺菌制御部50は、発煙装置10の紫外線発光素子36を数秒程度、発光駆動し、容器12に収納した発煙剤16に紫外線を照射して殺菌する制御を行う。 Further, when the first test start operation is performed by the remote control unit 205, the sterilization control unit 50 provided in the control unit 46 drives the ultraviolet light emitting element 36 of the smoke emitting device 10 to emit light for about several seconds, and the smoke generating agent stored in the container 12. Control is performed by irradiating 16 with ultraviolet rays to sterilize.

また、発煙装置10には、容器12の取出しを検出する容器取出検出スイッチ45が設けられており、発煙剤16を補充するために容器12を取り出すと容器取出検出スイッチ45がオンし、このとき制御部46に設けた殺菌制御部50は、紫外線発光素子36の発光駆動を禁止する制御を行い、紫外線が人の目に入って炎症等を引き起こすことを確実に防止し、高い安全性が確保される。 Further, the smoke emitting device 10 is provided with a container withdrawal detection switch 45 for detecting the withdrawal of the container 12, and when the container 12 is taken out to replenish the smoke generating agent 16, the container withdrawal detection switch 45 is turned on.
