Description

本発明は、エレベータかご内除菌装置に関する。   The present invention relates to an elevator car sterilization apparatus.

特許文献１は、エレベータかご内を除菌する技術を開示している。   Patent document 1 is disclosing the technique which disinfects the inside of an elevator car.

特許文献１は、エレベータかごの天井にイオン発生装置と送風装置を配置している。このイオン発生装置は、内部電極と外部電極の間に正電圧と負電圧からなる高圧パルス電圧を印加し、プラズマ放電を起こすことで外部電極の周囲空気をイオン化して略同数の正イオンと負イオンを発生するものである。   In Patent Document 1, an ion generator and a blower are arranged on the ceiling of an elevator car. This ion generator applies a high voltage pulse voltage consisting of a positive voltage and a negative voltage between an internal electrode and an external electrode, and causes plasma discharge to ionize the air around the external electrode to generate approximately the same number of positive ions and negative ions. It generates ions.

特許文献１は、送風装置を駆動して天井に設けた吸気口から空気を吸気して天井に設けた開口部からエレベータかご内に送風すると共に、イオン発生装置で発生させた正負イオンを送風にのせて開口部からエレベータかご内に放出するように動作する。   In Patent Document 1, air is sucked from an air inlet provided on the ceiling by driving the air blower and blown into an elevator car from an opening provided on the ceiling, and positive and negative ions generated by the ion generator are blown. It operates so as to be discharged from the opening into the elevator car.

このように、プラズマ放電で外部電極の周囲空気をイオン化して生成した正負イオンをエレベータかご内に放出することで、エレベータかご内の浮遊菌等の不活性化をしている。   As described above, positive and negative ions generated by ionizing the air around the external electrode by plasma discharge are released into the elevator car, thereby inactivating the floating bacteria in the elevator car.

特開２００４−９９２０５号公報JP 2004-99205 A

しかしながら、上記特許文献１に示された従来例は、イオン発生装置と送風装置をエレベータかごの出入口を設けた壁面の直上の天井部位に配置し、正負イオンを放出する開口部が出入口の真上の天井部分に開口している。   However, in the conventional example shown in Patent Document 1, the ion generator and the air blower are arranged in a ceiling portion directly above the wall surface provided with the entrance / exit of the elevator car, and the opening for discharging positive / negative ions is directly above the entrance / exit. Open to the ceiling.

このため、出入口の扉が開くと、天井に設けた開口部から正負イオンをエレベータかご内に放出しても、出入口から外に逃げ易い。特に、出入口の扉が開き、エレベータかご内から人が外（エレベータ乗り場）に出る際、外に出る人の動きに伴ってエレベータかご内から外に向けてわずかな空気の流れが生じ、この空気の流れに乗って正負イオンが外に逃げ易い。   For this reason, when the door of the doorway opens, even if positive and negative ions are released into the elevator car from the opening provided on the ceiling, it is easy to escape from the doorway. In particular, when the door of the entrance opens and a person goes out of the elevator car (elevator landing), a slight air flow is generated from the inside of the elevator car to the outside with the movement of the person going out. It is easy for positive and negative ions to escape outside.

このように従来は、出入口の扉が開く毎に、出入口から正負イオンが逃げるという問題がある。   Thus, conventionally, there is a problem that positive and negative ions escape from the entrance / exit each time the door of the entrance / exit is opened.

ところで、エレベータかご内の除菌は、特に出入口の扉を開いて搭乗者が出入りする際、及び、扉を閉じて直ぐに搭乗者を乗せてエレベータかごを昇降する際にエレベータかご内を除菌することが重要である。   By the way, the sterilization in the elevator car is particularly sterilized when the passenger opens and closes by opening the door of the doorway, and when the elevator car is lifted and lowered by closing the door. This is very important.

しかしながら、従来は、前述のように出入口の扉が開く毎に、出入口から正負イオンが逃げるので、エレベータかご内に滞留する正負イオンが少なくなり、搭乗者が出入りする際、及び、搭乗者を乗せてエレベータかごを昇降する際における除菌効果が低下する。   Conventionally, however, positive and negative ions escape from the entrance and exit each time the door of the entrance and exit is opened as described above, so that positive and negative ions staying in the elevator car are reduced, and when the passenger enters and exits, The sterilization effect when raising and lowering the elevator car is reduced.

本発明は上記の点に鑑みて発明したものであって、出入口の扉を開けて搭乗者が出入りする際、及び、搭乗者を乗せてエレベータかごを昇降する際におけるエレベータかご内の除菌効果の低下を抑制できるエレベータかご内除菌装置を提供するにある。   The present invention has been invented in view of the above points, and has a sterilization effect in an elevator car when a passenger enters and exits by opening an entrance door and when the elevator car is lifted and lowered with the passenger onboard. It is in providing the sterilization apparatus in an elevator car which can suppress the fall of this.

本発明のエレベータかご内除菌装置は、静電霧化により帯電微粒子液を発生させる静電霧化手段と、この静電霧化手段で発生された帯電微粒子水をエレベータかご内に放出する排気口と、前記静電霧化手段へと送風する空気を前記エレベータかご内から吸引する吸気口と、を備えたエレベータかご内除菌装置であって、前記エレベータかごの出入口が設けられた壁面以外の壁面上方の天井部位に前記排気口と前記吸気口とを設け、前記排気口から前記出入口が設けられた壁面以外の壁面に沿って前記帯電微粒子液を含んだ空気が下方に放出され、この帯電微粒子水を含んだ空気が上方の前記吸気口へと吸引されることで、この帯電微粒子水を含んだ空気が前記エレベータかご内を循環するようにしたことを特徴とする。   The elevator car sterilization apparatus of the present invention includes an electrostatic atomizing means for generating charged fine particle liquid by electrostatic atomization, and an exhaust for discharging charged fine particle water generated by the electrostatic atomizing means into the elevator car. An elevator car sterilization apparatus comprising a mouth and an air inlet for sucking air to be blown to the electrostatic atomizer from the elevator car, except for a wall surface provided with an entrance of the elevator car The exhaust port and the intake port are provided in a ceiling portion above the wall surface, and air containing the charged fine particle liquid is discharged downward along the wall surface other than the wall surface provided with the inlet / outlet from the exhaust port. The air containing the charged fine particle water is sucked into the upper intake port so that the air containing the charged fine particle water circulates in the elevator car.

また、前記静電霧化手段が、霧化電極に供給された水を静電霧化して帯電微粒子水を生成するものであることが好ましい。   Moreover, it is preferable that the said electrostatic atomization means produces | generates charged fine particle water by electrostatic atomizing the water supplied to the atomization electrode.

また、前記排気口と前記吸気口とを前記出入口が設けられた壁面と対向する奥側の壁面に沿って隣接配設することが好ましい。   Further, it is preferable that the exhaust port and the intake port are disposed adjacent to each other along a back wall surface facing the wall surface provided with the entrance / exit.

また、前記出入口が設けられた壁面以外の壁面に沿ってその巾方向の中程の部位で前記排気口と前記吸気口とを隣接配置することが好ましい。   Moreover, it is preferable to arrange | position the said exhaust port and the said intake port adjacently in the center part of the width direction along wall surfaces other than the wall surface in which the said entrance / exit was provided.

本発明は、出入口の扉を開け際に帯電微粒子水が出入口から外に逃げ難くなり、この結果、搭乗者が出入りする際、及び、扉を閉じて直ぐに搭乗者を乗せてエレベータかごを昇降する際における帯電微粒子水によるエレベータかご内の除菌効果の低下を抑制できる。   In the present invention, when the door of the entrance / exit is opened, the charged fine particle water is difficult to escape from the entrance / exit. As a result, when the passenger enters / exits and when the passenger closes the door, the passenger is put on the elevator car to move up and down. It is possible to suppress a decrease in the sterilization effect in the elevator car due to the charged fine particle water.

以下、本発明を添付図面に示す実施形態に基づいて説明する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

図１、図１乃至図７は一実施形態を示す。図１に示すように、エレベータかご１は、エレベータかご１内を除菌するエレベータかご内除菌装置２を備えている。   1 and 1 to 7 show an embodiment. As shown in FIG. 1, the elevator car 1 includes an elevator car sterilization apparatus 2 that sterilizes the elevator car 1.

エレベータかご内除菌装置２は、図２に示すように、液体を静電霧化して帯電微粒子液を発生させる静電霧化手段３と、この静電霧化手段３で発生された帯電微粒子水をエレベータかご１内に放出する排気口４と、静電霧化手段３へと送風する空気をエレベータかご１内から吸引する吸気口５を備えている。   As shown in FIG. 2, the elevator car sterilization apparatus 2 includes an electrostatic atomization means 3 that electrostatically atomizes a liquid to generate a charged fine particle liquid, and charged fine particles generated by the electrostatic atomization means 3. An exhaust port 4 for discharging water into the elevator car 1 and an intake port 5 for sucking air to be blown to the electrostatic atomizer 3 from the elevator car 1 are provided.

図２の実施形態においてエレベータかご内除菌装置２は、送風流路６を設けたハウジング７の下面に排気口４と吸気口５を有するグリル８を設け、送風流路６内に吸気口５から排気口４側にかけ順に送風ファン９、脱臭フィルタ１０、静電霧化手段３を配設している。   In the elevator car sterilizer 2 in the embodiment of FIG. 2, a grill 8 having an exhaust port 4 and an intake port 5 is provided on the lower surface of a housing 7 provided with an air flow channel 6, and the air intake port 5 is provided in the air flow channel 6. The blower fan 9, the deodorizing filter 10, and the electrostatic atomizing means 3 are disposed in order from the exhaust port 4 to the exhaust port 4 side.

なお、本実施形態において、静電霧化手段３、送風ファン９を制御する制御部をハウジング７の送風流路６を設けた部分以外の部分に内装している。   In the present embodiment, the controller for controlling the electrostatic atomizing means 3 and the blower fan 9 is provided in a portion other than the portion where the blower flow path 6 of the housing 7 is provided.

静電霧化手段３は、液体供給手段により霧化電極１５に供給した液体に高電圧を印加することで、液体を静電霧化して活性種をナノメータサイズの帯電微粒子液を生成するようになっている。   The electrostatic atomization means 3 applies a high voltage to the liquid supplied to the atomization electrode 15 by the liquid supply means so that the liquid is electrostatically atomized to generate a charged fine particle liquid having a nanometer size of active species. It has become.

図５にはその一例を示し、液体供給手段として、空気中の水分を結露水として生成して霧化電極１５に供給する例を示している。以下液体として水を例として説明し、同様に帯電微粒子液として帯電微粒子水を例として説明する。   One example is shown in FIG. 5, and an example is shown in which water in the air is generated as condensed water and supplied to the atomizing electrode 15 as a liquid supply means. Hereinafter, water will be described as an example of liquid, and similarly charged fine particle water will be described as an example of charged fine particle liquid.

すなわち静電霧化手段３は、霧化電極１５と、空気中の水分を結露水として生成することで霧化電極１５に水を供給するための冷却部１６と、供給した結露水を静電霧化するために霧化電極１５に高電圧を印加するための高電圧印加部１７とを備えている。   That is, the electrostatic atomizing means 3 electrostatically converts the atomized electrode 15, the cooling unit 16 for supplying water to the atomized electrode 15 by generating moisture in the air as condensed water, and the supplied condensed water. In order to atomize, the high voltage application part 17 for applying a high voltage to the atomization electrode 15 is provided.

図５に示す実施形態においてはペルチェユニットのような熱交換器１８の冷却部１６により空気中の水分を冷却して結露水を生成することで霧化電極１５に水を供給するようになっている。   In the embodiment shown in FIG. 5, water is supplied to the atomizing electrode 15 by cooling the moisture in the air by the cooling unit 16 of the heat exchanger 18 such as a Peltier unit to generate condensed water. Yes.

図５には熱交換器１８としてペルチェユニットの例を示している。ペルチェユニットは熱伝導性の高いアルミナや窒化アルミニウムからなる絶縁板の片面側に回路を形成してある一対のペルチェ回路板１９を、互いの回路が向き合うように対向させ、多数列設してある熱電素子２０を両ペルチェ回路板１９間で挟持すると共に隣接する熱電素子２０同士を両側の回路で電気的に接続して構成している。   FIG. 5 shows an example of a Peltier unit as the heat exchanger 18. In the Peltier unit, a pair of Peltier circuit boards 19 having a circuit formed on one side of an insulating plate made of alumina or aluminum nitride having high thermal conductivity are arranged in multiple rows so that the circuits face each other. The thermoelectric element 20 is sandwiched between the two Peltier circuit boards 19 and the adjacent thermoelectric elements 20 are electrically connected by circuits on both sides.

そして熱電素子２０への通電により一方のペルチェ回路板１９側から他方のペルチェ回路板１９側に向けて熱が移動するように構成している。   Then, heat is transferred from one Peltier circuit board 19 side to the other Peltier circuit board 19 side by energization of the thermoelectric element 20.

一方の側のペルチェ回路板１９の外側には冷却部１６を接続し、また、他方の側のペルチェ回路板１９の外側には放熱部２６を接続している。実施形態では放熱部２６として放熱フィンの例を示している。ペルチェユニットの冷却部１６には霧化電極１５の後端部を接続している。   A cooling unit 16 is connected to the outside of the Peltier circuit board 19 on one side, and a heat dissipation unit 26 is connected to the outside of the Peltier circuit board 19 on the other side. In the embodiment, an example of a heat radiating fin is shown as the heat radiating portion 26. A rear end portion of the atomizing electrode 15 is connected to the cooling portion 16 of the Peltier unit.

霧化電極１５は絶縁材料からなる筒体２１で囲まれており、筒体２１の周壁には筒体２１内外を連通する開口２２が設けている。また、筒体２１の先端開口部にリング状をした対向電極２３を配設し、霧化電極１５の軸心の延長線上にリング状の対向電極２３のリングの中心が位置するように霧化電極１５と対向電極２３とが対向している。なお、本発明においては対向電極２３を設けないものも含む。   The atomizing electrode 15 is surrounded by a cylinder 21 made of an insulating material, and an opening 22 that communicates the inside and outside of the cylinder 21 is provided on the peripheral wall of the cylinder 21. Further, a ring-shaped counter electrode 23 is disposed at the tip opening of the cylindrical body 21, and the atomization is performed so that the center of the ring of the ring-shaped counter electrode 23 is positioned on the extension line of the axis of the atomization electrode 15. The electrode 15 and the counter electrode 23 are opposed to each other. In addition, in this invention, what does not provide the counter electrode 23 is included.

上記静電霧化手段３は、ペルチェユニットに通電することで、冷却部１６を冷却し、冷却部１６を冷却することで霧化電極１５を冷却し、空気中の水分を結露して霧化電極１５に水（結露水）を供給するようになっている。   The electrostatic atomizer 3 cools the cooling unit 16 by energizing the Peltier unit, cools the atomizing electrode 15 by cooling the cooling unit 16, and condenses moisture in the air to atomize. Water (condensation water) is supplied to the electrode 15.

このように霧化電極１５に水が供給された状態で上記霧化電極１５と対向電極２３との間に高電圧を印加すると、霧化電極１５と対向電極２３との間にかけられた高電圧により霧化電極１５の先端部に供給された水と対向電極２３との間にクーロン力が働き、水の液面が局所的に錐状に盛り上がる。   Thus, when a high voltage is applied between the atomizing electrode 15 and the counter electrode 23 in a state where water is supplied to the atomizing electrode 15, the high voltage applied between the atomizing electrode 15 and the counter electrode 23. As a result, a Coulomb force acts between the water supplied to the tip of the atomizing electrode 15 and the counter electrode 23, and the liquid level of the water locally rises in a cone shape.

このように水の液面が錐状に盛り上がってテーラーコーンを形成すると、該テーラーコーンの先端に電荷が集中してこの部分における電界強度が大きくなって、これによりこの部分に生じるクーロン力が大きくなり、更にテーラーコーンが成長する。   When the level of water rises like a cone and forms a tailor cone in this way, the electric charge concentrates on the tip of the tailor cone and the electric field strength in this portion increases, thereby increasing the Coulomb force generated in this portion. And tailor cones grow.

このようにテーラーコーンが成長し該テーラーコーンの先端に電荷が集中して電荷の密度が高密度となると、テーラーコーンの先端部分の水が大きなエネルギー（高密度となった電荷の反発力）を受け、表面張力を超えて***・飛散（レイリー***）を繰り返して活性種を含むマイナス又はプラスに帯電したナノメータサイズの帯電微粒子水を大量に生成させて筒体２１の先端開口部から送風流路６内に放出するように構成している。   When the tailor cone grows like this and the charge concentrates on the tip of the tailor cone and the density of the charge becomes high, the water at the tip of the tailor cone has a large energy (repulsive force of the charge that has become dense). Receiving and repeatedly splitting and scattering (Rayleigh splitting) beyond the surface tension to generate a large amount of negatively or positively charged nanometer-size charged fine particle water containing active species, and blowing air from the opening at the tip of the cylinder 21 6 is configured to be discharged into the inside.

前記構成のエレベータかご内除菌装置２は、エレベータかご１の天井１１部位に配置する。   The elevator car disinfection device 2 having the above-described configuration is disposed at the ceiling 11 portion of the elevator car 1.

本実施形態においては、天井１１に設けた孔にエレベータかご内除菌装置２を嵌め込み、エレベータかご内除菌装置２の大部分を天井１１の上方に配設し、天井１１下面においてグリル８部分のみがエレベータかご１内に露出するように配置する。   In the present embodiment, the elevator car sterilization apparatus 2 is fitted into a hole provided in the ceiling 11, the most part of the elevator car sterilization apparatus 2 is disposed above the ceiling 11, and the grill 8 part is provided on the lower surface of the ceiling 11. So that only the elevator car 1 is exposed.

これにより、グリル８に設けた排気口４と吸気口５が天井１１の下面側においてエレベータかご１内に開口する。   As a result, the exhaust port 4 and the intake port 5 provided in the grill 8 are opened in the elevator car 1 on the lower surface side of the ceiling 11.

また、排気口４と吸気口５は、出入口１２が設けられた壁面１３以外の壁面１４に沿ってその巾方向の中程の部位の上方の天井１１部位に隣接配置するのが好ましい。   In addition, the exhaust port 4 and the intake port 5 are preferably disposed adjacent to the ceiling 11 site above the middle site in the width direction along the wall surface 14 other than the wall surface 13 provided with the entrance 12.

本実施形態では、図１、図３、図４に示すように、エレベータかご１の出入口１２が設けられた壁面１３と対向する奥側の壁面１４の上方の天井１１部位に排気口４と吸気口５を設けている。   In this embodiment, as shown in FIGS. 1, 3, and 4, the exhaust port 4 and the intake air are provided in the ceiling 11 portion above the wall surface 14 on the back side facing the wall surface 13 provided with the entrance 12 of the elevator car 1. A mouth 5 is provided.

また、この実施形態では、図１、図２、図４に示すように、奥側の壁面１４の巾方向の中程の部位の上方の天井１１部位に排気口４と吸気口５を奥側の壁面１４に沿って隣接配置している。   Moreover, in this embodiment, as shown in FIG.1, FIG.2, FIG.4, the exhaust port 4 and the intake port 5 are made into the back side in the ceiling 11 site | part above the center part of the width direction of the wall surface 14 of the back side. Are disposed adjacent to each other along the wall surface 14.

エレベータかご１の前記出入口１２が設けられた壁面１３又はそれ以外の壁面１４のいずれかに静電霧化手段３を操作するための操作部２４を設けている。   An operation unit 24 for operating the electrostatic atomizing means 3 is provided on either the wall surface 13 provided with the doorway 12 of the elevator car 1 or the other wall surface 14.

操作部２４を操作して静電霧化手段３をオンにすると、ペルチェユニットに通電して冷却部１６により霧化電極１５を冷却し、空気中の水分を結露して霧化電極１５に水（結露水）を供給する。   When the operation unit 24 is operated to turn on the electrostatic atomizer 3, the Peltier unit is energized to cool the atomization electrode 15 by the cooling unit 16, and moisture in the air is condensed to form water on the atomization electrode 15. Supply (condensation water).

この霧化電極１５に供給された水に高電圧を印加して静電霧化することで活性種を含むナノメータサイズの帯電微粒子水を大量に生成し、送風流路６内に放出する。   A large amount of nanometer-sized charged fine particle water containing active species is generated by applying a high voltage to the water supplied to the atomizing electrode 15 and electrostatically atomizing it, and discharging it into the air flow path 6.

このような帯電微粒子水の生成と同時に送風ファン９を駆動し、吸気口５からエレベータかご１内の空気を送風流路６に吸い込み、送風流路６内に放出された帯電微粒子水を含んだ空気を排気口４からエレベータかご１内に放出する。   Simultaneously with the generation of the charged fine particle water, the blower fan 9 is driven, the air in the elevator car 1 is sucked into the blower flow path 6 from the intake port 5, and the charged fine particle water released into the blower flow path 6 is included. Air is discharged into the elevator car 1 from the exhaust port 4.

排気口４から下方に放出された帯電微粒子水を含んだ空気は、排気口４を出入口１２が設けられた壁面１３と対向する奥側の壁面１４上方の天井１１部位に設けてあるので、排気口４の下方の壁面１４に沿ってエレベータかご１の下部に流れる。   The air containing the charged fine particle water discharged downward from the exhaust port 4 is provided at the site of the ceiling 11 above the inner wall 14 facing the wall 13 provided with the inlet / outlet 12. It flows to the lower part of the elevator car 1 along the wall surface 14 below the mouth 4.

また、エレベータかご１の下部の帯電微粒子水を含んだ空気は、出入口１２が設けられた壁面１３と対向する奥側の壁面１４に沿って上方に流れて該壁面１４の上方の吸気口５から送風流路６内に吸引される。   Further, the air containing charged fine particle water at the lower part of the elevator car 1 flows upward along the wall surface 14 on the back side facing the wall surface 13 provided with the inlet / outlet port 12, and from the intake port 5 above the wall surface 14. The air is sucked into the air flow path 6.

送風流路６に吸引された空気は、帯電微粒子水が放出される部分に供給され、帯電微粒子水を含んだ空気が再び排気口４から、出入口１２が設けられた壁面１３と対向する奥側の壁面１４に沿ってエレベータかご１の下部の下部に流れる。   The air sucked into the air flow path 6 is supplied to the portion from which the charged fine particle water is discharged, and the air containing the charged fine particle water again passes from the exhaust port 4 to the wall 13 where the inlet / outlet 12 is provided. Along the wall surface 14 of the elevator car 1 and flows to the lower part of the lower part of the elevator car 1.

このようにして送風流路６を介してエレベータかご１内を循環する帯電微粒子水を含んだ空気の循環流が形成される。   In this way, a circulating flow of air containing charged fine particle water circulating in the elevator car 1 through the air flow path 6 is formed.

この帯電微粒子水を含んだ空気の循環流は図６、図７の矢印のようにエレベータかご１内を流れることになる。   The circulating flow of the air containing the charged fine particle water flows through the elevator car 1 as shown by the arrows in FIGS.

放出された帯電微粒子水は既に述べたように活性種を含んでいるので、エレベータかご１内を浮遊する細菌やウイルスを不活性化する効果（これを除菌効果と称する）があり、また、脱臭効果、花粉を不活性化する効果等がある。   Since the discharged charged fine particle water contains active species as described above, it has an effect of inactivating bacteria and viruses floating in the elevator car 1 (this is called a sterilization effect), and Deodorizing effect, inactivating pollen, etc.

既に述べたように、エレベータかご１内の除菌はエレベータかごに搭乗者がいない時に内部を除菌するだけでなく、出入口１２の扉２７を開いて搭乗者が出入りする際、及び、搭乗者を乗せてエレベータかご１を昇降する際にも内部を効果的に除菌することが重要である。   As already described, the sterilization of the elevator car 1 not only sterilizes the interior when there is no passenger in the elevator car, but also when the passenger enters and exits by opening the door 27 of the entrance 12 and the passenger. It is important to effectively sterilize the interior even when the elevator car 1 is raised and lowered with a vehicle.

ここで、帯電微粒子水を含んだ空気は前述のように出入口１２から離れた壁面１４に沿って循環するので、エレベータかご１の出入口１２に設けた扉２７を開いても帯電微粒子水が出入口１２から外（乗り場）に流出し難くなる。   Here, since the air containing the charged fine particle water circulates along the wall surface 14 away from the entrance 12 as described above, the charged fine particle water remains in the entrance 12 even when the door 27 provided at the entrance 12 of the elevator car 1 is opened. It will be difficult to flow out of the car (outside).

また、出入口１２の扉２７が開き、エレベータかご１内から搭乗者が外に出る際に、エレベータかご１内から外に向けてわずかに空気流が生じるが、前記のように出入口１２から離れたところで循環流が形成されるので、搭乗者が外に出る際も帯電微粒子水が外に逃げ難い。   Further, when the door 27 of the entrance / exit 12 is opened and the passenger goes out from the elevator car 1, a slight air flow is generated from the inside of the elevator car 1 to the outside. By the way, since a circulation flow is formed, it is difficult for the charged fine particle water to escape outside even when the passenger goes outside.

この結果、出入口１２の扉２７が開いて搭乗者が出入りしている間におけるエレベータかご１内における帯電微粒子水の浮遊量の減少を抑制でき、帯電電微粒子水によるエレベータかご１内の除菌効果、脱臭効果の低下を抑制できる。   As a result, it is possible to suppress a decrease in the floating amount of charged fine particle water in the elevator car 1 while the door 27 of the entrance 12 is opened and a passenger enters and leaves, and the sterilization effect in the elevator car 1 due to the charged fine particle water. In addition, it is possible to suppress a decrease in the deodorizing effect.

したがって、出入口１２の扉２７を開いて搭乗者がエレベータかご１内に入いる際に搭乗者と共にエレベータかご１内に侵入する細菌やウイルスに対して、エレベータかご１内を浮遊する十分な量の帯電微粒子水により侵入と同時に効果的に除菌、脱臭ができる。   Accordingly, when the passenger 27 enters the elevator car 1 by opening the door 27 of the entrance 12, a sufficient amount of floating in the elevator car 1 against bacteria and viruses that enter the elevator car 1 together with the passenger. The charged fine particle water can effectively sterilize and deodorize at the same time as intrusion.

同様に、出入口１２の扉２７を閉じてエレベータかご１を昇降している間も、出入口１２の扉２７を閉じた直後であるといえども、エレベータかご１内を十分な量の帯電微粒子水が浮遊しているので、効果的に除菌、脱臭ができる。   Similarly, while the door 27 of the doorway 12 is closed and the elevator car 1 is moved up and down, even when the door 27 of the doorway 12 is closed, a sufficient amount of charged fine particle water is contained in the elevator car 1. Since it is floating, it can be sterilized and deodorized effectively.

また、天井１１に設けた排気口４から放出された帯電微粒子水を含む空気が出入口１２と対向する壁面１４に沿って下方に流れる際、該空気は壁面１４に沿いながら次第に下広がりになって下降し、これに伴い、帯電微粒子水も次第に下広がりに分散しながら下降し、一部は空気流から離れてエレベータかご１内を浮遊する。   Further, when the air containing the charged fine particle water discharged from the exhaust port 4 provided on the ceiling 11 flows downward along the wall surface 14 facing the entrance 12, the air gradually spreads along the wall surface 14. Along with this, the charged fine particle water also descends while gradually spreading downward, and a part of the charged fine particle water moves away from the air flow and floats in the elevator car 1.

一方、エレベータかご１の下部の空気は、出入口１２が設けられた壁面１３と対向する奥側の壁面１４に沿って下から上に向けて次第に奥側の壁面１４側に集めながら吸気口５に吸引されるので、エレベータかご１内の空気の循環が効果的に行われる。   On the other hand, the air in the lower part of the elevator car 1 is gradually gathered from the bottom toward the top along the back wall 14 facing the wall 13 provided with the entrance 12, and is collected on the back wall 14. Since the air is sucked, the air in the elevator car 1 is circulated effectively.

したがって、エレベータかご内除菌装置２の運転中、エレベータかご１内は帯電微粒子水が隅々まで飛翔する状態を維持できる。   Therefore, during operation of the elevator car sterilizer 2, the state in which the charged particulate water flies to every corner in the elevator car 1 can be maintained.

ここで、奥側の壁面１４に沿って下降する空気流は、床面付近での流速をほぼゼロに近い流速にしてもよい。   Here, the air flow descending along the wall surface 14 on the back side may have a flow velocity near the floor surface almost equal to zero.

このようにすることで、奥側の壁面１４に沿って下降する空気流に乗って下方に移送された帯電微粒子水が床面に当たって付着する量を減らし、エレベータかご１内を浮遊する量を増大し、除菌効果や脱臭効果を向上できる。   By doing so, the amount of charged fine particle water that has been transported downward on the airflow descending along the wall surface 14 on the back side hits the floor surface is reduced, and the amount that floats in the elevator car 1 is increased. In addition, the sterilizing effect and the deodorizing effect can be improved.

また、図２に示すように、送風流路６内に脱臭フィルタ１０を配置することで、吸気口５から送風流路６内に吸引した空気を、この脱臭フィルタ１０によっても脱臭することができ、脱臭効果がより向上する。   In addition, as shown in FIG. 2, by disposing the deodorization filter 10 in the air flow path 6, the air sucked into the air flow path 6 from the intake port 5 can also be deodorized by this deodorization filter 10. The deodorizing effect is further improved.

ここで、脱臭フィルタ１０を静電霧化手段３よりも上流側に配置しているので、静電霧化手段３で生成した帯電微粒子水のラジカルは、清浄な空気に含まれて排気口４からエレベータかご１内に放出されることになる。   Here, since the deodorizing filter 10 is disposed on the upstream side of the electrostatic atomizing means 3, the radicals of the charged fine particle water generated by the electrostatic atomizing means 3 are contained in clean air and are discharged from the exhaust port 4. Will be discharged into the elevator car 1 from.

この結果、帯電微粒子水に含まれたラジカルが未反応の状態で排気口４からエレベータかご１内に放出されて、エレベータかご１内を浮遊しながら細菌や臭気と反応して不活性化することになり、エレベータかご１内における除菌効果や脱臭効果がより向上する。   As a result, radicals contained in the charged fine particle water are released into the elevator car 1 from the exhaust port 4 in an unreacted state, and react with bacteria and odors while being suspended in the elevator car 1 to be inactivated. Thus, the sterilization effect and deodorization effect in the elevator car 1 are further improved.

なお、操作部２４をオンすることで、エレベータかご内除菌装置２を連続運転し、オフすることで、連続運転を停止するようにしてもよいが、操作部２４をオンすることで、エレベータかご内除菌装置２を一定時間運転し、その後自動的に所定時間運転を停止し、その後、再び一定時間運転するということを交互に繰り返すような間欠運転をおこなってもよい。   In addition, although the operation part 24 is turned on, the elevator car sterilization apparatus 2 may be continuously operated and turned off, and the continuous operation may be stopped. However, when the operation part 24 is turned on, the elevator An intermittent operation may be performed in which the sterilization apparatus 2 in the car is operated for a certain period of time, then the operation is automatically stopped for a predetermined period, and then the operation is performed again for a certain period of time.

間欠運転の例としては、例えば３０分運転し、その後、１時間運転停止をし、これを交互に繰り返す例を例示できるが、必ずしもこれにのみ限定されるものではない。   As an example of the intermittent operation, for example, the operation is performed for 30 minutes, and then the operation is stopped for one hour, and this is alternately repeated. However, the operation is not necessarily limited thereto.

前記実施形態では、エレベータかご１の一壁面１３に出入口１２を設け、この出入口１２を設けた壁面１３と対向する奥側の壁面１４の上方の天井１１部位に排気口４と吸気口５を設けた例を示したが必ずしもこれにのみ限定されるものではない。   In the above-described embodiment, the entrance / exit 12 is provided on one wall surface 13 of the elevator car 1, and the exhaust port 4 and the intake port 5 are provided in the ceiling 11 portion above the wall surface 14 on the inner side facing the wall surface 13 provided with the entrance / exit 12.
