Abstract
Description
本発明は、泥棒が侵入した際の侵入警報信号等によって起動される装置であり、室内や店舗内に霧を充満させて視界を妨げ、泥棒の窃盗行為そのものを不可能にさせる霧噴射装置に関するものである。 The present invention relates to a device activated by an intrusion warning signal or the like when a thief invades, and relates to a mist injection device that fills a room or a store with fog to obstruct the view and makes the thief's theft itself impossible. It is a thing.
霧噴射装置は、金庫を置いた室内や、宝石や高級腕時計などの貴金属を陳列したショーケースがたくさん並んだ貴金属店の店舗内等に設置して用いるものであり、セキュリティシステムが泥棒を検出したときに、一定時間霧を噴射し、室内を視界不良状態にし、泥棒の行動を阻止するものである。霧を発生させる基本原理は周知であり、実用化されている。 The mist injection device is installed in a room with a safe or in a precious metal store where many showcases displaying precious metals such as jewelry and luxury watches are lined up, and the security system detected a thief. Occasionally, fog is sprayed for a certain period of time to make the room poorly visible and prevent thieves from acting. The basic principle of fog generation is well known and has been put to practical use.
霧噴射装置の基本構成は、噴射液をたくわえる容器、容器内の噴射液を吸い出し加熱器に送り込むポンプ、噴射液を高温に加熱し霧状にしてノズルから噴射させる加熱器からなるものであり、そのほか、ポンプの作動と停止、加熱器の温度をコントロールする制御部を備えている（例えば、特許文献１参照）。 The basic configuration of the mist injection device consists of a container that stores the injection liquid, a pump that sucks out the injection liquid in the container and sends it to the heater, and a heater that heats the injection liquid to a high temperature to atomize it and inject it from the nozzle. In addition, it includes a control unit that controls the operation and stop of the pump and the temperature of the heater (see, for example, Patent Document 1).
噴射液としては、ジプロピレングリコールやトリエチレングリコール等のグリコール類と水やアルコールとの混合液を使用するのが一般的である。 As the injection liquid, a mixed liquid of glycols such as dipropylene glycol and triethylene glycol and water or alcohol is generally used.
従来の霧噴射装置においては、ポンプが動き続けることで、噴射液が常に加熱器内に流れ、次々に液が気化することで噴射口から霧が勢いよく押し出され続けて噴出するが、ポンプが止まると噴射液の流れが止まり、加熱器内の液は熱で気化された状態が保持され、加熱器以外では、噴射液が液体として充満された状態でとどまることになる。 In a conventional mist injection device, when the pump keeps moving, the injection liquid always flows into the heater, and the liquid evaporates one after another, so that the mist is continuously pushed out from the injection port and ejected. When it is stopped, the flow of the injection liquid is stopped, the liquid in the heater is maintained in a state of being vaporized by heat, and other than the heater, the injection liquid remains in a state of being filled as a liquid.
加熱器は霧を噴射していないときも予熱しており、ノズルや加熱器とポンプ間のパイプにとどまっている噴射液に加熱器の熱が継続して加わるが、加熱器から離れた位置にある噴射液は気化する温度にならずに、液体のまま酸化反応（液の劣化）が促進され噴射液が茶褐色などに変色したり、粘性が高くなったりする。その液が、ノズルやパイプなどに残留する恐れや、霧を噴射する際にノズルから出て周囲を汚す恐れがあった。 The heater is preheated even when it is not injecting mist, and the heat of the heater is continuously applied to the injection liquid remaining in the nozzle or the pipe between the heater and the pump, but at a position away from the heater. A certain injection liquid does not reach a temperature at which it vaporizes, and the oxidation reaction (deterioration of the liquid) is promoted as it is, and the injection liquid turns brown or becomes brown or becomes highly viscous. There was a risk that the liquid would remain on the nozzles and pipes, and that the liquid would come out of the nozzles and pollute the surroundings when the mist was sprayed.
このため、定期的に噴射のテスト動作をさせ劣化した噴射液を綺麗な噴射液で送り出す必要があったが、テスト動作は手動で行っており、定期的にテスト動作をさせるために機器設置場所まで行くか、遠隔で動作入力を与える必要があり、手間がかかっていた。 For this reason, it was necessary to periodically perform an injection test operation and send out the deteriorated injection liquid with a clean injection liquid, but the test operation is performed manually, and the equipment installation location is required to perform the test operation on a regular basis. It was troublesome because I had to go to or give the operation input remotely.
また、噴射後にパイプにたまった液を機器内部で一旦受け皿にためる構造の機器も存在するが、定期的にその受け皿の廃液を捨てる作業が必要になり、手間がかかっていた。 In addition, there is a device having a structure in which the liquid accumulated in the pipe after injection is temporarily stored in the saucer inside the device, but it is necessary to periodically discard the waste liquid in the saucer, which is troublesome.
上記課題を解決するために、本発明の霧噴射装置は、噴射液をたくわえる噴射液容器と、起動信号を受け付けた後に、予め定めた第１の設定時間だけ、前記噴射液を吸いだし、加熱器に送り込むポンプと、前記噴射液を加熱し霧状にしてノズルから噴射させる加熱器とを備え、前記噴射液容器と前記ポンプ間に気体取込部を設け、第１の設定時間終了後に予め定めた第２の設定時間だけ、前記気体取込部から気体を前記ポンプにより前記加熱器に送り込む。 In order to solve the above problems, the mist injection device of the present invention sucks out the injection liquid and heats it for a predetermined first set time after receiving the injection liquid container for storing the injection liquid and the start signal. A pump for feeding the injection liquid and a heater for heating the injection liquid into a mist and injecting the injection liquid from a nozzle are provided. A gas intake portion is provided between the injection liquid container and the pump, and a gas intake unit is provided in advance after the end of the first set time. The gas is sent from the gas intake unit to the heater by the pump for a set second set time.
本発明によれば、ノズルやパイプにとどまる噴射液を気体取込部から取り込んだ気体で送り出すことにより排出し、加熱器の熱影響を受ける範囲に噴射液がとどまることがなくなり、噴射液の酸化反応（劣化）が起こらなくなる。よって、粘性の高い変色した液などが、霧を噴射する際にノズルから出て周囲を汚すことや、ノズルやパイプなどに残留することがなくなる。これに伴い、定期的な噴射のテスト動作や廃液を捨てる作業をする必要がなくなる。 According to the present invention, the injection liquid that stays in the nozzle or pipe is discharged by being sent out by the gas taken in from the gas intake unit, the injection liquid does not stay in the range affected by the heat of the heater, and the injection liquid is oxidized. Reaction (deterioration) does not occur. Therefore, the highly viscous discolored liquid or the like does not come out from the nozzle when the mist is sprayed and pollute the surroundings, and does not remain in the nozzle or the pipe. Along with this, it is not necessary to perform regular injection test operations and waste liquid disposal work.
図１は、本発明の霧噴射装置の第１の実施形態の概略を示したブロック図である。１は噴射液をたくわえておく噴射液容器、２はポンプ、３は噴射液を急激に加熱して霧を作り出す加熱器、４は霧を噴射するノズル、５、６、７は金属製のパイプ、１１は空気を取り込むための気体取込部である。気体取込部１１は２方弁αを備え、２方弁αは噴射液容器内の噴射液より高い位置になるようにしている。加熱器３は、予め高温状態に保たれた加熱装置を内蔵しており、ポンプ２の働きにより勢いよく流入する噴射液は、ここで急激に加熱され気化し、霧となって、ノズル４から噴出する。噴射液としては、ジプロピレングリコールやトリエチレングリコール等のグリコール類と水やアルコールとの混合液が一般的である。 FIG. 1 is a block diagram showing an outline of a first embodiment of the mist injection device of the present invention. 1 is an injection liquid container that stores the injection liquid, 2 is a pump, 3 is a heater that rapidly heats the injection liquid to create mist, 4 is a nozzle that injects mist, and 5, 6 and 7 are metal pipes. , 11 are gas intake units for taking in air. The gas intake unit 11 is provided with a two-way valve α so that the two-way valve α is located higher than the injection liquid in the injection liquid container. The heater 3 has a built-in heating device that has been kept at a high temperature in advance, and the jet liquid that flows vigorously by the action of the pump 2 is rapidly heated here and vaporized to become mist from the nozzle 4. Squirt. As the injection liquid, a mixed liquid of glycols such as dipropylene glycol and triethylene glycol and water or alcohol is generally used.
図９は、加熱器３の構造を示した図である。加熱器３は、円筒形のヒーター３２を備え、ヒーター３２の外周を上下方向に伸びる螺旋状のパイプ３１が巻かれている。噴射液は、パイプ７を介しパイプ３１の下部に送られ、ヒーター３２で急激に加熱され気化し、パイプ３１の上部からノズル４へ送られ霧となって噴出される。 FIG. 9 is a diagram showing the structure of the heater 3. The heater 3 includes a cylindrical heater 32, and a spiral pipe 31 extending in the vertical direction around the outer circumference of the heater 32 is wound around the heater 3. The injection liquid is sent to the lower part of the pipe 31 via the pipe 7, is rapidly heated by the heater 32 and vaporized, is sent from the upper part of the pipe 31 to the nozzle 4, and is ejected as mist.
図示は省略するが、霧噴射装置は、霧噴射用の起動信号を受け付け、ポンプ２を所定の時間だけ駆動したり、加熱器３の温度や気体取込部１１（２方弁α）の動作を制御したりする働きを担う制御部を備えている。さらに、噴射液容器１の外周には、ヒーターを巻きつけた放熱板を設け、パイプ５の先端（噴射液吸入部）に熱電対などの温度測定器が取り付けられており、ヒーターの温度制御を行っている。噴射液容器１を接続するナットなどの固定部を介して、パイプ５が噴射液容器１に接続されている。噴射液容器１は、ヒーターの上から保温材によって覆われている。 Although not shown, the mist injection device receives a start signal for mist injection, drives the pump 2 for a predetermined time, and operates the temperature of the heater 3 and the gas intake unit 11 (two-way valve α). It is equipped with a control unit that is responsible for controlling the gas. Further, a heat radiating plate around which a heater is wound is provided on the outer circumference of the injection liquid container 1, and a temperature measuring device such as a thermocouple is attached to the tip of the pipe 5 (injection liquid suction part) to control the temperature of the heater. Is going. The pipe 5 is connected to the injection liquid container 1 via a fixing portion such as a nut that connects the injection liquid container 1. The jet liquid container 1 is covered with a heat insulating material from above the heater.
所定の温度以下になったことを熱電対で検知し、ヒーターをオンにし、放熱板を加熱することで放熱板から発せられる熱により、噴射液が温められると、その温度が、熱電対に伝わり、所定の温度以上になったことを熱電対で検知して、ヒーターをオフにする。この一連の動作により、噴射液容器１内の噴射液は、低温となって粘度が高くなる前に加熱され、粘度の低い状態が維持される。 When the injection liquid is warmed by the heat generated from the heat dissipation plate by detecting that the temperature has fallen below the specified temperature with the thermocouple, turning on the heater, and heating the heat dissipation plate, that temperature is transmitted to the thermocouple. , The thermocouple detects that the temperature has exceeded the specified temperature and turns off the heater. By this series of operations, the injection liquid in the injection liquid container 1 is heated before the temperature becomes low and the viscosity becomes high, and the low viscosity state is maintained.
図１と図２を用いて霧噴射時の動作を説明する。図２は、２方弁αの状態を示した図であり、図２（ａ）が待機時の状態、図２（ｂ）が第１の設定時間の状態、図２（ｃ）は第２の設定時間の状態である。 The operation at the time of mist injection will be described with reference to FIGS. 1 and 2. 2A and 2B are views showing a state of the two-way valve α, FIG. 2A is a state in standby mode, FIG. 2B is a state of a first set time, and FIG. 2C is a second state. It is the state of the set time of.
霧噴射装置は、金庫などが置かれた重点警戒エリア内に設置され、泥棒が侵入した際に作動するセキュリティシステムからの起動信号を受けて霧を噴射する。起動信号を受けて即座に霧を噴射する必要があるため、待機時においても電源が供給され、加熱器３が予熱されるようになっている。待機時では２方弁αは「閉」状態となっている。 The fog injection device is installed in a priority warning area where a safe or the like is placed, and injects fog in response to an activation signal from a security system that operates when a thief invades. Since it is necessary to immediately inject mist in response to the start signal, power is supplied even during standby, and the heater 3 is preheated. During standby, the two-way valve α is in the “closed” state.
起動信号を受け付けると、第１の設定時間から第２の設定時間にかけてポンプ２を駆動する。第１の設定時間においては、２方弁αは「閉」状態であり、噴射液容器内の噴射液がパイプ５、気体取込部１１、パイプ６、ポンプ２、パイプ７を介して、加熱器３へ送りこまれ、加熱器３にて高温に加熱され霧状になって、ノズル４から噴射される。 When the start signal is received, the pump 2 is driven from the first set time to the second set time. In the first set time, the two-way valve α is in the “closed” state, and the injection liquid in the injection liquid container is heated via the pipe 5, the gas intake portion 11, the pipe 6, the pump 2, and the pipe 7. It is sent to the vessel 3, heated to a high temperature by the heater 3, atomized, and injected from the nozzle 4.
第１の設定時間終了後、第２の設定時間だけ、２方弁αは「開」状態となり、α２からα１の方向に周囲の空気が流れ込み、パイプ５内の噴射液は噴射液容器１に戻り、パイプ６、ポンプ２、パイプ７、加熱器３、ノズル４に残った噴射液はノズル４から噴射され、とどまらないようになる。また、２方弁αは噴射液容器内の噴射液より高い位置のため、α２側へ噴射液が漏れることはない。
第２の設定時間終了後は、待機時に戻り、ポンプ２は停止し、２方弁αは「閉」状態となる。
After the end of the first set time, the two-way valve α is in the "open" state for the second set time, the surrounding air flows in the direction from α2 to α1, and the injection liquid in the pipe 5 enters the injection liquid container 1. Returning, the injection liquid remaining in the pipe 6, the pump 2, the pipe 7, the heater 3, and the nozzle 4 is injected from the nozzle 4 and does not stay. Further, since the two-way valve α is located higher than the injection liquid in the injection liquid container, the injection liquid does not leak to the α2 side.
After the end of the second set time, the pump 2 returns to the standby state, the pump 2 is stopped, and the two-way valve α is in the “closed” state.
第１の設定時間は霧噴射装置が設置される部屋の大きさとポンプ２の排出量を考慮して決定し、第２の設定時間は気体取込部１１から加熱器３までの間の液量とポンプ２の排出量を考慮し決定する。 The first set time is determined in consideration of the size of the room in which the mist injection device is installed and the discharge amount of the pump 2, and the second set time is the amount of liquid between the gas intake unit 11 and the heater 3. And the discharge amount of the pump 2 are taken into consideration.
図１０のようなヒーター１０２の外周を左右方向に伸びる螺旋状のパイプ１０１が巻かれている加熱器１００を用いた場合、空気をパイプ１０１内に送り込んだとしても内部にたまっている飽和蒸気は送り込んだ空気とともに送り出されるが、パイプ１０１内に噴射液が残留する場合がある。そして空気の送り込みが止まると残った噴射液が再度蒸発し、飽和蒸気１０４となりパイプ１０１の螺旋上部にたまる。パイプ１０１内部の蒸気が飽和状態となり気化しきれない噴射液１０３は、パイプ１０１の螺旋下部にとどまり、加熱され続け、酸化反応（液の劣化）が促進される。 When a heater 100 in which a spiral pipe 101 extending in the left-right direction is wound around the outer circumference of the heater 102 as shown in FIG. 10, even if air is sent into the pipe 101, the saturated steam accumulated inside is Although it is sent out together with the sent air, the injection liquid may remain in the pipe 101. Then, when the air supply is stopped, the remaining injection liquid evaporates again to become saturated vapor 104, which accumulates in the upper part of the spiral of the pipe 101. The injection liquid 103 in which the vapor inside the pipe 101 is saturated and cannot be completely vaporized stays at the lower part of the spiral of the pipe 101 and continues to be heated, and the oxidation reaction (deterioration of the liquid) is promoted.
しかし、図９のようなヒーター３２の外周を上下方向に伸びる螺旋状のパイプ３１が巻かれ、パイプ３１の上部からノズル４へ霧を送る加熱器３を用いることで、噴射液は気化した蒸気が上昇する性質により上部にあるノズル４へ向かうと共に、パイプ７から加熱器３へ空気を送り込むと、パイプ３１内は飽和蒸気量が低下し乾燥した状態となることで、パイプ３１内の液体は空気中に取り込まれやすくなり、パイプ３１内に残る噴射液をなくすことができる。 However, the jet liquid is vaporized steam by using a heater 3 in which a spiral pipe 31 extending in the vertical direction is wound around the outer circumference of the heater 32 as shown in FIG. 9 and a mist is sent from the upper portion of the pipe 31 to the nozzle 4. When air is sent from the pipe 7 to the heater 3 while heading toward the nozzle 4 at the upper part due to the property of rising, the saturated vapor amount in the pipe 31 decreases and the pipe 31 becomes dry, so that the liquid in the pipe 31 becomes dry. It becomes easy to be taken into the air, and the injection liquid remaining in the pipe 31 can be eliminated.
ノズルやパイプにとどまる噴射液を気体取込部から取り込んだ空気で送り出すことにより排出し、加熱器の熱影響を受ける範囲に噴射液がとどまることがなくなる。 The injection liquid that stays in the nozzle or pipe is discharged by being sent out by the air taken in from the gas intake part, and the injection liquid does not stay in the range affected by the heat of the heater.
図３は、本発明の霧噴射装置の第２の実施形態の概略を示したブロック図である。第１の実施形態と第２の実施形態とは気体取込部のみ異なり、他は同じ構成である。第２の実施形態では気体取込部１２に３方弁βを備えており、気体取込部１２（３方弁β）は、第１の実施形態の気体取込部１１（２方弁α）と同様に制御部（図示省略）により動作が制御される。 FIG. 3 is a block diagram showing an outline of a second embodiment of the mist injection device of the present invention. The first embodiment and the second embodiment differ only in the gas intake portion, and the other embodiments have the same configuration. In the second embodiment, the gas intake unit 12 is provided with a three-way valve β, and the gas intake unit 12 (three-way valve β) is the gas intake unit 11 (two-way valve α) of the first embodiment. ), The operation is controlled by the control unit (not shown).
図３と図４を用いて霧噴射時の動作を説明する。図４は、３方弁βの状態を示した図であり、図４（ａ）が待機時の状態、図４（ｂ）が第１の設定時間の状態、図４（ｃ）は第２の設定時間の状態である。 The operation at the time of mist injection will be described with reference to FIGS. 3 and 4. 4A and 4B are views showing a state of the three-way valve β, FIG. 4A is a state in standby mode, FIG. 4B is a state of a first set time, and FIG. 4C is a second state. It is the state of the set time of.
霧噴射装置は、起動信号を受けて即座に霧を噴射する必要があるため、待機時においても電源が供給され、加熱器３が予熱されるようになっている。待機時では３方弁βは、β１が「開」状態、β２が「閉」状態、β３が「開」状態となっている。 Since the mist injection device needs to immediately inject mist in response to the start signal, power is supplied even during standby, and the heater 3 is preheated. In the standby state, β1 is in the “open” state, β2 is in the “closed” state, and β3 is in the “open” state of the three-way valve β.
起動信号を受け付けると、第１の設定時間から第２の設定時間にかけてポンプ２を駆動する。第１の設定時間においては、３方弁βは、β１が「開」状態、β２が「閉」状態、β３が「開」状態であり、噴射液容器内の噴射液がパイプ５、気体取込部１２、パイプ６、ポンプ２、パイプ７を介して、加熱器３へ送りこまれ、加熱器３にて高温に加熱され霧状になって、ノズル４から噴射される。 When the start signal is received, the pump 2 is driven from the first set time to the second set time. In the first set time, the three-way valve β has β1 in the “open” state, β2 in the “closed” state, and β3 in the “open” state, and the injection liquid in the injection liquid container is the pipe 5 and gas removal.

Air flows in, and the injection liquid remaining in the pipe 6, the pump 2, the pipe 7, the heater 3, and the nozzle 4 is injected from the nozzle 4 and does not stay.
第２の設定時間終了後は、待機時に戻り、ポンプ２は停止し、３方弁βは、β１が「開」状態、β２が「閉」状態、β３が「開」状態となる。 After the end of the second set time, the pump 2 returns to the standby state, the pump 2 is stopped, and the three-way valve β is in the “open” state of β1, the “closed” state of β2, and the “open” state of β3.
第２の設定時間において、第１の実施形態では、２方弁αが噴射液容器１内の噴射液より低い位置にするとサイフォンの原理により噴射液が２方弁αのα２側へ流れ出る可能性があるため、２方弁αを噴射液容器１内の噴射液より高い位置にする必要があったが、図４（ｃ）の状態でβ１が「閉」状態となっているため、第１の実施形態とは異なり、３方弁βを噴射液容器１内の噴射液より低い位置にしても、３方弁βから外へ液が漏れることはなく、どの位置にでも配置が可能である。 In the second set time, in the first embodiment, if the two-way valve α is set at a position lower than the injection liquid in the injection liquid container 1, the injection liquid may flow out to the α2 side of the two-way valve α according to the siphon principle. Therefore, it was necessary to position the two-way valve α higher than the injection liquid in the injection liquid container 1, but since β1 is in the “closed” state in the state of FIG. 4C, the first Even if the three-way valve β is placed at a position lower than the injection liquid in the injection liquid container 1, the liquid does not leak to the outside from the three-way valve β and can be arranged at any position. ..
第１の実施形態において、待機時は図２（ａ）のように２方弁αを「閉」状態としたが、「開」状態としてもよい。また、第２の実施形態において、待機時は図４（ａ）のように３方弁βをβ１が「開」状態、β２が「閉」状態、β３が「開」状態としたが、β１、β２、β３は「開」状態と「閉」状態のどちらでもよい。 In the first embodiment, the two-way valve α is set to the “closed” state as shown in FIG. 2A during standby, but it may be set to the “open” state. Further, in the second embodiment, β1 is in the “open” state, β2 is in the “closed” state, and β3 is in the “open” state as shown in FIG. 4A during standby, but β1 , Β2 and β3 may be in either the “open” state or the “closed” state.

所定の温度以下になったことを熱電対で検知し、ヒーターをオンにし、放熱板を加熱することで放熱板から発せられる熱により、噴射液が温められると、その温度が、熱電対に伝わり、所定の温度以上に温まったことを検知して、ヒーターをオフにすることで、噴射液容器１内の噴射液は、低温となって粘度が高くなる前に加熱され、粘度の低い状態が維持される。 When the injection liquid is warmed by the heat generated from the heat radiating plate by detecting that the temperature has fallen below the specified temperature with the thermocouple, turning on the heater, and heating the heat radiating plate, the temperature is transmitted to the thermocouple. By detecting that the temperature has risen above a predetermined temperature and turning off the heater, the injection liquid in the injection liquid container 1 is heated before the temperature becomes low and the viscosity becomes high, and the state of low viscosity is maintained. Be maintained.
図５と図６を用いて霧噴射時の動作を説明する。図６は、２方弁γの状態を示した図であり、図６（ａ）が待機時の状態、図６（ｂ）が第１の設定時間の状態、図６（ｃ）は第３の設定時間の状態である。 The operation at the time of mist injection will be described with reference to FIGS. 5 and 6. 6A and 6B are views showing a state of the two-way valve γ, FIG. 6A is a state in standby mode, FIG. 6B is a state of a first set time, and FIG. 6C is a third state. It is the state of the set time of.
霧噴射装置は、起動信号を受けて即座に霧を噴射する必要があるため、待機時においても電源が供給され、加熱器３が予熱されるようになっている。待機時では２方弁γは「閉」状態となっている。 Since the mist injection device needs to immediately inject mist in response to the start signal, power is supplied even during standby, and the heater 3 is preheated. In the standby state, the two-way valve γ is in the “closed” state.
起動信号を受け付けると、第１の設定時間だけポンプ２を駆動する。第１の設定時間においては、２方弁γは「閉」状態であり、噴射液容器内の噴射液がパイプ８、ポンプ２、パイプ９、気体取込部１３、パイプ１０を介して、加熱器３へ送りこまれ、加熱器３にて高温に加熱され霧状になって、ノズル４から噴射される。 When the start signal is received, the pump 2 is driven for the first set time. In the first set time, the two-way valve γ is in the “closed” state, and the injection liquid in the injection liquid container is heated via the pipe 8, the pump 2, the pipe 9, the gas intake unit 13, and the pipe 10. It is sent to the vessel 3, heated to a high temperature by the heater 3, atomized, and injected from the nozzle 4.
第１の設定時間終了後、第３の設定時間だけ、２方弁γは「開」状態となり、圧縮ボンベＧ内の気体が圧縮ボンベＧの圧力によりγ２からγ１の方向に流れ込み、パイプ１０、加熱器３、ノズル４に残った噴射液はノズル４から噴射され、とどまらないようになる。
第３の設定時間終了後は、待機時に戻り、２方弁γは「閉」状態となる。
After the end of the first set time, the two-way valve γ is in the “open” state for the third set time, and the gas in the compression cylinder G flows in the direction from γ2 to γ1 due to the pressure of the compression cylinder G, and the pipe 10. The injection liquid remaining in the heater 3 and the nozzle 4 is injected from the nozzle 4 and does not stay there.
After the end of the third set time, the two-way valve γ returns to the standby state and is in the “closed” state.
図１０のようなヒーター１０２の外周を左右方向に伸びる螺旋状のパイプ１０１が巻かれている加熱器１００を用いた場合、気体をパイプ１０１内に送り込んだとしても内部にたまっている飽和蒸気は送り込んだ気体とともに送り出されるが、パイプ１０１内に噴射液が残留する場合がある。そして気体の送り込みが止まると残った噴射液が再度蒸発し、飽和蒸気１０４となりパイプ１０１の螺旋上部にたまる。パイプ１０１内部の蒸気が飽和状態となり気化しきれない噴射液１０３は、パイプ１０１の螺旋下部にとどまり、加熱され続け、酸化反応（液の劣化）が促進される。 When a heater 100 in which a spiral pipe 101 extending in the left-right direction is wound around the outer circumference of the heater 102 as shown in FIG. 10, even if gas is sent into the pipe 101, the saturated steam accumulated inside is Although it is sent out together with the sent gas, the injection liquid may remain in the pipe 101. Then, when the gas feeding is stopped, the remaining injection liquid evaporates again to become saturated vapor 104, which accumulates in the upper part of the spiral of the pipe 101. The injection liquid 103 in which the vapor inside the pipe 101 is saturated and cannot be completely vaporized stays at the lower part of the spiral of the pipe 101 and continues to be heated, and the oxidation reaction (deterioration of the liquid) is promoted.
しかし、図９のようなヒーター３２の外周を上下方向に伸びる螺旋状のパイプ３１が巻かれ、パイプ３１の上部からノズル４へ霧を送る加熱器３を用いることで、噴射液は気化した蒸気が上昇する性質により上部にあるノズル４へ向かうと共に、パイプ１０から加熱器３へ気体を送り込むと、パイプ３１内は飽和蒸気量が低下し乾燥した状態となることで、パイプ３１内の液体は気体中に取り込まれやすくなり、パイプ３１内に残る噴射液をなくすことができる。 However, by using a heater 3 in which a spiral pipe 31 extending in the vertical direction is wound around the outer periphery of the heater 32 as shown in FIG. 9 and a mist is sent from the upper portion of the pipe 31 to the nozzle 4, the injection liquid is vaporized steam. When gas is sent from the pipe 10 to the heater 3 while heading toward the nozzle 4 at the upper part due to the property of rising, the amount of saturated steam in the pipe 31 decreases and the liquid in the pipe 31 becomes dry. It becomes easy to be taken into the gas, and the injection liquid remaining in the pipe 31 can be eliminated.
第３の設定時間において、２方弁γが「開」状態となったとしても圧縮ボンベＧの圧力により、噴射液が圧縮ボンベＧに流れ込むことはなく、気体取込部１３はポンプ２と加熱器３間のどの位置にでも配置可能である。 In the third set time, even if the two-way valve γ is in the “open” state, the injection liquid does not flow into the compression cylinder G due to the pressure of the compression cylinder G, and the gas intake unit 13 heats with the pump 2. It can be placed at any position between the vessels 3.
第１の設定時間は霧噴射装置が設置される部屋の大きさとポンプ２の排出量を考慮して決定し、第３の設定時間は気体取込部１３から加熱器３までの間の液量と圧縮ボンベＧの圧力を考慮し決定する。 The first set time is determined in consideration of the size of the room in which the mist injection device is installed and the discharge amount of the pump 2, and the third set time is the amount of liquid between the gas intake unit 13 and the heater 3. And the pressure of the compression cylinder G are taken into consideration when determining.
ノズルやパイプにとどまる噴射液を気体取込部から取り込んだ気体で送り出すことにより排出し、加熱器の熱影響を受ける範囲に噴射液がとどまることがなくなる。 The injection liquid that stays in the nozzle or pipe is discharged by being sent out by the gas taken in from the gas intake part, and the injection liquid does not stay in the range affected by the heat of the heater.
