Description

本発明は、水に通電することにより得られる電解水を用いて、空気中の細菌、真菌、ウイルス、臭いなどの除去を行う電解水成分の揮発装置に関するものである。   The present invention relates to an electrolyzed water component volatilizer that removes bacteria, fungi, viruses, odors and the like in the air using electrolyzed water obtained by energizing the water.
従来のこの種の揮発装置の構造は、以下のようになっていた。   The structure of the conventional volatile device of this type is as follows.
すなわち、次亜塩素酸などの揮発させる成分を含む水を水槽に供給し、水槽の表面に沿って空気を送風して次亜塩素酸を揮発させ、所定のエリアに送風して、除菌、消臭する構成となっていた(例えば下記特許文献1)。   That is, water containing components to be volatilized such as hypochlorous acid is supplied to the water tank, air is blown along the surface of the water tank to volatilize hypochlorous acid, and the air is blown to a predetermined area to sterilize the bacteria. It became a structure which deodorizes (for example, following patent document 1).
特許第4588104号公報Patent No. 4588104 gazette
この種の次亜塩素酸水溶液を室内空気に接触させて、除菌、消臭を行う揮発装置においては、安定した濃度で次亜塩素酸を揮発させ、除菌消臭効果を維持することが求められる。しかしながら、従来の構成によると、次亜塩素酸の水溶液を貯留する水槽の濃度を安定させて維持することが困難である。なぜなら、給水と排水を一つの水槽で同時に行う構成としているため、新たな次亜塩素酸水溶液を給水しても、元の希薄な水溶液に希釈され、所定の濃度まで上昇せず、目的の性能が得られない。   In a volatilizer that performs sterilization and deodorization by contacting the aqueous solution of hypochlorous acid of this type with room air, the hypochlorous acid is volatilized at a stable concentration to maintain the sterilization and deodorizing effect. Desired. However, according to the conventional configuration, it is difficult to stabilize and maintain the concentration of the water tank storing the aqueous solution of hypochlorous acid. Because the water supply and drainage are performed simultaneously in one water tank, even if a new aqueous solution of hypochlorous acid is supplied, it is diluted to the original dilute aqueous solution and does not rise to a predetermined concentration, and the target performance is achieved. Can not be obtained.
また、除菌性能を発揮するにあたっては、目標の濃度に達しているかどうかが極めて重要であり、所定濃度に到達してはじめて目標時間内での除菌が実現できる。そのため、水槽の次亜塩素酸水溶液が希釈されてしまうことは、除菌を行う装置として致命的な課題である。あるいは完全に水槽の水を入れ替えるために多くの次亜塩素酸の水溶液が必要となり、装置が大型化してしまうという問題も生じる。   In addition, it is extremely important whether or not the target concentration is reached in achieving the sterilization performance, and it is possible to achieve sterilization within the target time only after reaching the predetermined concentration. Therefore, dilution of the aqueous solution of hypochlorous acid in the water tank is a fatal problem as an apparatus for sterilization. Alternatively, many hypochlorous acid aqueous solutions are required to completely replace the water in the water tank, which causes a problem of upsizing of the apparatus.
そこで、本発明は上記課題を解決するものであり、安定して次亜塩素酸水溶液の濃度を保つことで、除菌、脱臭性能を維持することができる揮発装置を提供することを目的としている。   Then, this invention solves the said subject and it aims at providing the volatilization apparatus which can maintain bacteria removal and deodorizing performance by maintaining the density | concentration of hypochlorous acid aqueous solution stably. .
そして、この目的を達成するために本発明は、次亜塩素酸を含有する水素イオン濃度が3.0以上8.5以下の次亜塩素酸水溶液を保持するトレイと、前記トレイの次亜塩素酸水溶液から次亜塩素酸を揮発させるための通風揮発手段と、前記通風揮発手段に交差して送風する送風手段と、運転制御を行う制御手段とを備え、次亜塩素酸水溶液に含まれる非解離型の次亜塩素酸を揮発させて空間に拡散し、気体状の次亜塩素酸で所定の空間を除菌する揮発装置であって、前記トレイの次亜塩素酸水溶液を排水する排水手段と、次亜塩素酸水溶液を供給するための給水タンクと、前記給水タンクと前記トレイと前記排水手段を一方向の流れで連通するように配置した通水路を備え、前記トレイの次亜塩素酸水溶液の濃度が低下したときに前記排水手段を駆動させて排水し、前記排水手段の排水速度よりも小さい速度で前記給水タンクから給水を行うことを特徴としたものである。そして、これら手段により、初期の目的を達成するものである。   And in order to achieve this object, according to the present invention, there is provided a tray for holding an aqueous solution of hypochlorous acid having a hydrogen ion concentration of 3.0 or more and 8.5 or less containing hypochlorous acid, and hypochlorous acid in the tray A ventilating / volatilizing means for volatilizing hypochlorous acid from an aqueous acid solution, a blowing means for blowing air across the ventilating / volatilizing means, and a control means for performing operation control, which are not included in the hypochlorous acid aqueous solution It is a volatilization apparatus which volatilizes dissociative hypochlorous acid, diffuses it into space, and sterilizes a predetermined space with gaseous hypochlorous acid, which is a drainage means for draining the aqueous solution of hypochlorous acid in the tray And a water supply tank for supplying a hypochlorous acid aqueous solution, and a water passage arranged to connect the water supply tank, the tray, and the drainage means in a unidirectional flow, and the hypochlorous acid of the tray When the concentration of the aqueous solution decreases, the drainage Drained by driving the stage, in which is characterized in that supply the water from the water supply tank with a smaller rate than the rate of drainage of the drainage means. And by these means, the initial purpose is achieved.
以上のように本発明は、トレイの次亜塩素酸水溶液の濃度が低下して次亜塩素酸水溶液を濃度が高いものに入れ替える装置において、通水路を介して次亜塩素酸水溶液を一方向の流れでトレイから排水手段側へ供給する構成としておき、トレイの次亜塩素酸水溶液が、古いものと新しいものが混合しないように給水速度を遅く、排水速度を速くして水溶液の入れ替えをすることで、効率よく確実にトレイの次亜塩素酸水溶液を目標の濃度に設定することができる。これにより、次亜塩素酸水溶液の濃度低下による揮発量低下を防ぎ、次亜塩素酸を安定した濃度で揮発させることで、高い脱臭、除菌効果を保つことできる。   As described above, according to the present invention, in the apparatus in which the concentration of the aqueous solution of hypochlorous acid in the tray is reduced and the aqueous solution of hypochlorous acid is replaced with a high concentration solution, the aqueous solution of hypochlorous acid is unidirectionally Supply water from the tray to the drainage means side by flow, slow the water supply speed so that the aqueous solution of hypochlorous acid in the tray does not mix old and new, and increase the drainage speed to replace the aqueous solution. Thus, the hypochlorous acid aqueous solution in the tray can be efficiently and reliably set to the target concentration. Thereby, the reduction of the volatilization amount due to the concentration reduction of the hypochlorous acid aqueous solution is prevented, and the high deodorization and the sterilizing effect can be maintained by volatilizing the hypochlorous acid at a stable concentration.

A substantially rectangular air inlet 2 is provided on both side surfaces of the main body case 1, and a substantially rectangular air outlet 3 is provided on the top surface of the main body case 1.
図2に示すように、この本体ケース1内には、送風手段4と通風揮発手段5を備えている。   As shown in FIG. 2, in the main body case 1, an air blowing means 4 and a ventilation volatilization means 5 are provided.
送風手段4は、本体ケース1の上部に設けられ、モータとモータにより回転する羽根車とそれらを囲むケースとから構成したシロッコファンである。   The blower means 4 is a sirocco fan which is provided on the upper part of the main body case 1 and includes a motor and an impeller rotated by the motor and a case surrounding them.
通風揮発手段5は、あらかじめ調製された次亜塩素酸水溶液を貯水するトレイ6と、トレイ6に次亜塩素酸水溶液を供給する給水タンク7と、トレイ6内の次亜塩素酸水溶液に一部を浸漬した揮発部材8とから構成している。   Ventilation volatilization means 5 includes a tray 6 for storing hypochlorous acid aqueous solution prepared in advance, a water supply tank 7 for supplying hypochlorous acid aqueous solution to tray 6, and a part of hypochlorous acid aqueous solution in tray 6 And the volatilized member 8 in which the
揮発部材8を構成する材料としては、電解水に反応性の少ない材料、即ち、電解水による劣化が少ない材料、例えばポリオレフィン系樹脂(ポリエチレン樹脂、ポリプロピレン樹脂等)、PET(ポリエチレン・テレフタラート樹脂)、塩化ビニル樹脂、フッ素系樹脂(PTFE、PFA、ETFE等)、セルロース系材料又はセラミック系材料等が使用され、本実施例では、ポリエステルが採用される。   The material constituting the volatilization member 8 is a material that is less reactive to electrolyzed water, that is, a material that is less deteriorated by electrolyzed water, such as polyolefin resin (polyethylene resin, polypropylene resin, etc.), PET (polyethylene terephthalate resin), A vinyl chloride resin, a fluorine-based resin (PTFE, PFA, ETFE, etc.), a cellulose-based material, a ceramic-based material or the like is used, and in this embodiment, polyester is adopted.
トレイ6は、天面を開口した箱形状をしており、水を貯水できる構造となっており、本体ケース1の下部に配置され、本体ケース1から水平方向にスライドして着脱可能となっている。   The tray 6 has a box shape with an open top, and is structured to be able to store water, and is disposed at the lower part of the main body case 1 so as to slide horizontally from the main body case 1 to be removable. There is.
給水タンク7は本体ケース1内部の正面側に、トレイ6に内蔵される形で設置され、トレイ6から着脱可能な構造となっている。   The water supply tank 7 is installed on the front side of the inside of the main body case 1 so as to be built in the tray 6 and has a structure that can be detached from the tray 6.
揮発部材8は、トレイ6において給水タンク7から供給される次亜塩素酸水溶液と、送風手段4によって本体ケース1内に吸込まれた室内空気とを接触させる部材である。さらに揮発部材8は、中空円筒状に構成され、円筒部分に空気が流通可能な孔を備えており、その円筒部分の一部がトレイ6の次亜塩素酸水溶液に浸漬できるように、トレイ6に回転自在に内蔵されている。通風揮発手段5において揮発した気体状の次亜塩素酸を含む空気は、連通する空気流路9を通じて吹出口3から室内に放出される。   The volatilization member 8 is a member that brings the aqueous solution of hypochlorous acid supplied from the water supply tank 7 in the tray 6 into contact with the room air sucked into the main body case 1 by the blower 4. Furthermore, the volatilization member 8 is formed in a hollow cylindrical shape, and the cylindrical portion is provided with a hole through which air can flow, so that a portion of the cylindrical portion can be immersed in the hypochlorous acid aqueous solution of the tray 6. It is rotatably incorporated in the The air containing gaseous hypochlorous acid volatilized in the ventilation volatilization means 5 is discharged into the room from the blowout port 3 through the communicating air flow path 9.
次亜塩素酸水を入れるトレイ6は、次亜塩素酸水溶液が空気から吸収した汚れの増加や、次亜塩素酸の揮発によって、次亜塩素酸の濃度が低下する。そのため、次亜塩素酸水溶液の濃度低下にあわせて、濃度が十分に高い次亜塩素酸水溶液と交換する必要がある。そのため、トレイ6に貯留される次亜塩素酸水溶液を排水するための排水手段である排水ポンプ10を設ける。排水ポンプ10は、浸漬型、あるいは配管を介した吸水型のものがあり、いずれのものに限定されないが、構造が簡易的である点で浸漬型が好ましい。排水ポンプ10の駆動は、電磁式、ダイアフラム式、遠心式、チューブ式などが知られているが、いずれのものに限定されないが、流量の調整が容易な遠心式がよい。   In the tray 6 containing hypochlorous acid water, the concentration of hypochlorous acid decreases due to the increase in the amount of soil absorbed by the aqueous hypochlorous acid solution from the air and the volatilization of hypochlorous acid. Therefore, it is necessary to replace with an aqueous solution of hypochlorous acid having a sufficiently high concentration in accordance with the decrease in the concentration of the aqueous solution of hypochlorous acid. Therefore, the drainage pump 10 which is a drainage means for draining the hypochlorous acid aqueous solution stored in the tray 6 is provided. The drainage pump 10 may be an immersion type or a water absorption type through a pipe, and is not limited to any type, but the immersion type is preferable in that the structure is simple. Although the electromagnetic pump, diaphragm type, centrifugal type, tube type, etc. are known for driving the drainage pump 10, the type is not limited to any type, but a centrifugal type with easy adjustment of the flow rate is preferable.
トレイ6には、給水タンク7から揮発部材8を通じて排水ポンプ10までを連通する通水路11を備える。通水路11は、揮発部材8や排水ポンプ10付近に貯留される次亜塩素酸水溶液が、給水タンク7付近の新鮮な次亜塩素酸水溶液と混合せず、一方通行で流れるように側壁が構成される。また、底部には一定の傾斜を設けて排水ポンプ10側への水の誘導、排出がスムーズに行うようにできるとより好ましい。   The tray 6 is provided with a water passage 11 communicating the water supply tank 7 to the drainage pump 10 through the volatilization member 8. The water passage 11 has a side wall so that the aqueous solution of hypochlorous acid stored near the volatilization member 8 and the drainage pump 10 does not mix with the fresh aqueous solution of hypochlorous acid near the water supply tank 7 and flows in one way. Be done. Further, it is more preferable that a constant slope be provided at the bottom to smoothly guide and discharge water to the drainage pump 10 side.
給水タンク7からトレイ6への給水は、所定のタイミングで適宜行えるように給水制御を行えることが求められる。給水を行う方法としては、適切な流量で行えることができればよく、電気式のポンプによる給水や、重力滴下式などがあるがいずれの方法でもよい。以下では、構造が簡易的な重力滴下式について説明する。   Water supply from the water supply tank 7 to the tray 6 is required to be able to perform water supply control so that it can be appropriately performed at a predetermined timing. As a method of supplying water, any method may be used as long as it can be performed at an appropriate flow rate, and there are water supply by an electric pump, a gravity dripping method, and the like, but any method may be used. Below, the gravity dripping type | formula whose structure is simple is demonstrated.
重力滴下式においては、給水タンク7は圧力によって開閉が制御される水栓12により給水が制御される。トレイ6に給水タンク7を設置すると、底面側になるように設置された水栓12が解放し、大気圧によって空気が給水タンク内に入り、タンク内の次亜塩素酸水溶液が押し出されてトレイ6に供給される構造となっている。水面が水栓12まで上昇してくると、水面により給水タンク7が密閉され、水の供給が停止し、常に一定量まで給水することができる。すなわち、次亜塩素酸水溶液を交換するタイミングで排水ポンプ10を駆動することで、トレイ6の水面が下がり、給水タンク7内に空気が進入してトレイ6に所定量まで自動で給水することができる。   In the gravity dripping type, the water supply tank 7 is controlled for water supply by a faucet 12 whose opening and closing is controlled by pressure. When the water supply tank 7 is installed in the tray 6, the faucet 12 installed so as to be on the bottom side is released, the air enters the water supply tank by atmospheric pressure, and the aqueous solution of hypochlorous acid in the tank is pushed out. It has a structure to be supplied to 6. When the water surface rises to the faucet 12, the water surface seals the water supply tank 7, the water supply is stopped, and the water can be constantly supplied up to a fixed amount. That is, by driving the drainage pump 10 at the timing of replacing the hypochlorous acid aqueous solution, the water surface of the tray 6 is lowered, and the air enters the water supply tank 7 to automatically supply the tray 6 with a predetermined amount. it can.
給水タンク7からトレイ6に給水される給水速度は、トレイ6の使用済みの次亜塩素酸水溶液に新しい次亜塩素酸水溶液が混合されずに排水できるように設定する必要がある。このためには、排水ポンプ10の排水速度よりも、給水速度が小さくなるようにする。他の設計事項との調整によるものであるが、例えば水栓12の開口面積を小さくする、水栓12に抵抗体を設けるなどの手法を用いることができる。一方、排水速度を給水速度に対して十分に大きくすることも本発明においては同義である。そのため、排水ポンプ10の流量を増やすことで給水速度と排水速度の調整を行なっても良い。排水ポンプ10の流量は、設計仕様上大きいものを採用するか、または例えば遠心式であれば電圧または周波数など、電源の入力特性を増加することで流量を上げることができる。   It is necessary to set the water supply speed supplied from the water supply tank 7 to the tray 6 so that the new aqueous solution of hypochlorous acid can be drained without being mixed with the used aqueous solution of hypochlorous acid in the tray 6. For this purpose, the water supply rate is set to be smaller than the drainage rate of the drainage pump 10. Although it is based on adjustment with other design matters, methods such as reducing the opening area of the faucet 12 or providing a resistor on the faucet 12 can be used, for example. On the other hand, making the drainage rate sufficiently larger than the water supply rate is also the same in the present invention. Therefore, the water supply rate and the drainage rate may be adjusted by increasing the flow rate of the drainage pump 10. The flow rate of the drainage pump 10 may be large in design specifications, or may be increased by, for example, increasing the input characteristics of the power supply, such as voltage or frequency in the case of a centrifugal type.
排水速度は、トレイ6に貯留される使用済みの次亜塩素酸水溶液が迅速に排出されることが好ましく、トレイ6の貯留槽の容積をVとすると、排水速度は毎分V以上がよく、より好ましくは、図3に示すように、毎分Vの2倍容から10倍容である。給水速度は、図3に示すように、排水速度よりも小さい値とする必要があり、好ましくは排水速度の1/2から1/10倍速である。   As for the drainage rate, it is preferable that the spent hypochlorous acid aqueous solution stored in the tray 6 be quickly drained, and if the volume of the reservoir of the tray 6 is V, the drainage rate is preferably V per minute or more, More preferably, as shown in FIG. 3, it is twice to 10 times volume of V per minute. As shown in FIG. 3, the water supply rate needs to be a value smaller than the drainage rate, and is preferably 1/2 to 1/10 of the drainage rate.
排水ポンプ10は、駆動し続けるとトレイ6の次亜塩素酸水溶液が渇水してしまうため、排水速度の比に応じて、およそ排水が完了した時点で停止させる必要がある。例えば、排水速度がVの10倍容であって給水/排水速度比が1/2倍の場合には、排水ポンプ10駆動開始から60秒後に停止させると完全に排水することができ、1/10倍の場合には7秒後に停止させるとよく、このとき給水が完了するまでにかかる合計給水量は1/2倍に対して約1/2で済む。これにより、排水量、給水量を少なくすることができ、本体を小さく構成することができる。   If the drainage pump 10 continues to be driven, the hypochlorous acid aqueous solution in the tray 6 suffers from drought, so it is necessary to stop the drainage pump 10 when drainage is completed, according to the drainage speed ratio. For example, if the drainage speed is 10 times the volume V and the feed water / drainage speed ratio is 1/2, it can be completely drained if it is stopped 60 seconds after the start of operation of the drainage pump 10, 1 / In the case of 10 times, it is good to stop after 7 seconds, and at this time, the total water supply amount required until water supply is completed is only about 1/2 to 1/2. Thereby, the amount of drainage and the amount of water supply can be reduced, and the main body can be configured to be small.
給排水工程について図4を用いて説明する。   The water supply and drainage process will be described with reference to FIG.
まず、図4(a)に示すように、給水タンク7をトレイ6に設置すると、トレイ6に次亜塩素酸水溶液が給水される。次に揮発運転工程を行い、次亜塩素酸を揮発させた後、排水ポンプ10を動作させてトレイ6の次亜塩素酸水溶液を排水する。このとき、図4(b)のように給水速度は排水速度に比べて小さいためトレイ6の水位はほぼなくなる。所定時間排水をしたのち、図4(c)のように、排水ポンプ10を停止させると、給水タンク7から新たな次亜塩素酸水溶液が給水され、トレイ6の水位が上昇し、所定の水位まで到達すると給水が自動で停止する。   First, as shown in FIG. 4A, when the water supply tank 7 is installed in the tray 6, the aqueous solution of hypochlorous acid is supplied to the tray 6. Next, a volatilization operation step is performed, and after the hypochlorous acid is volatilized, the drainage pump 10 is operated to drain the hypochlorous acid aqueous solution of the tray 6. At this time, as shown in FIG. 4B, since the water supply rate is smaller than the drain rate, the water level of the tray 6 almost disappears. After draining for a predetermined time, as shown in FIG. 4 (c), when the drainage pump 10 is stopped, a new aqueous solution of hypochlorous acid is supplied from the water supply tank 7, the water level of the tray 6 rises, and the predetermined water level The water supply will stop automatically when it reaches it.
排水ポンプ10や送風手段4などの動作を制御するために制御手段13を設ける。制御手段13には、あらかじめ制御動作を記憶したマイコンや、動作を開始、変更するためのスイッチ部などから構成されており、使用者は適宜必要に応じて動作制御を行えるように配置される。   A control means 13 is provided to control the operation of the drainage pump 10, the air blowing means 4 and the like. The control means 13 comprises a microcomputer storing the control operation in advance, a switch unit for starting and changing the operation, and the like, and is arranged so that the user can appropriately control the operation as needed.
揮発部材8は、駆動モータ14による回転がなされ、次亜塩素酸水溶液と室内空気を連続的に接触させる構造となっている。揮発部材8の回転速度を大きくすると、揮発部材8全体に付着する次亜塩素酸水溶液の量が増え、加湿量が増加することが知られている。また、逆に回転速度を小さくすると、揮発量を減らすことができる。そのため、室内環境の温度に応じた回転数の設定を行うと、次亜塩素酸の過剰な揮発による不快感を防ぐことができる。   The volatilization member 8 is rotated by the drive motor 14 so that the hypochlorous acid aqueous solution and the room air are continuously brought into contact with each other. It is known that when the rotational speed of the volatilization member 8 is increased, the amount of the aqueous solution of hypochlorous acid adhering to the entire volatilization member 8 increases and the amount of humidification increases. Conversely, if the rotational speed is reduced, the amount of volatilization can be reduced. Therefore, by setting the number of rotations according to the temperature of the indoor environment, it is possible to prevent an unpleasant sensation due to excessive volatilization of hypochlorous acid.
また、被処理空気の温度を検知するための温度センサ15を吸気口2の周辺に配し、検知した室内空気の温度に基づいて、次亜塩素酸の揮発量を推定し、運転開始から排水ポンプ10を駆動するまでの時定数τを設定すると、排水タイミングをより正確に推定できるため好ましい。図5に給排水制御と時定数τ、次亜塩素酸濃度の状態を示す。   In addition, a temperature sensor 15 for detecting the temperature of the air to be treated is disposed around the inlet 2, and the volatilized amount of hypochlorous acid is estimated based on the detected temperature of the indoor air, and drainage is started from the start of operation. It is preferable to set a time constant τ until the pump 10 is driven, because drainage timing can be estimated more accurately. FIG. 5 shows the state of water supply and drainage control, time constant τ, and hypochlorous acid concentration.
次亜塩素酸濃度次亜塩素酸の揮発量は、通常のヘンリー則に則った気液平衡反応に準ずることが本発明者らによって確認されており、図6(a)に示すように、空気中の次亜塩素酸の濃度比は、空間温度20℃を1とすると、30℃では1.3倍、15℃では0.7倍であって、その中間は線形に推移する。揮発速度の変動に応じて、トレイ6の次亜塩素酸水溶液が所定濃度以下にまで揮発する時間は変動するため、被処理空気の温度によって時定数τを変更することが好ましく、τを標準条件(空間温度20℃)に対する揮発速度の値で除した値とすると、次亜塩素酸を枯渇させないように運転することができる。   It has been confirmed by the present inventors that the volatilized amount of hypochlorous acid concentration follows the vapor-liquid equilibrium reaction in accordance with the normal Henry's law, and as shown in FIG. Assuming that the space temperature 20 ° C. is 1, the concentration ratio of hypochlorous acid in the medium is 1.3 times at 30 ° C. and 0.7 times at 15 ° C., and the intermediate transition shifts linearly. Since the time during which the aqueous solution of hypochlorous acid in tray 6 volatilizes to a predetermined concentration or less changes according to the fluctuation of the evaporation rate, it is preferable to change the time constant τ according to the temperature of the air to be treated. If it is divided by the value of the volatilization rate with respect to (space temperature 20 ° C.), it can be operated so as not to deplete hypochlorous acid.
また、次亜塩素酸の揮発量は、温度以外にも、揮発部材8に送風する風量によっても変動する。風量は、制御手段13によって送風手段4が設定されて決まるが、設定風量が大きいほど揮発量は大きくなり、時定数τを短く設定することが求められる。揮発部材8の揮発効率にもよるが、例えば、図6(b)に示すように、次亜塩素酸の単位時間あたりの揮発量は、標準条件の風量を毎分5立米とすると、毎分7立米では1.2倍、毎分3立米では0.7倍となる。これに基づいて、時定数τも、標準条件に対して、除した値とするとよく、例えば毎分5立米を1とすると、毎分7立米では0.7とすると風量に応じて最適なタイミングで排水制御を行うことができる。   In addition to the temperature, the volatilized amount of hypochlorous acid also varies depending on the amount of air blown to the volatilization member 8. The air volume is determined by setting the air blowing means 4 by the control means 13, but as the set air volume is larger, the volatilization amount becomes larger, and it is required to set the time constant τ short. Depending on the volatilization efficiency of the volatilization member 8, for example, as shown in FIG. 6 (b), the volatilization amount of hypochlorous acid per unit time can be calculated as follows, assuming that the air volume of standard conditions is 5 cubic meters per minute. It will be 1.2 times in 7-round rice and 0.7-fold in 3 rounds per minute. Based on this, the time constant τ may be a value obtained by dividing the standard condition, for example, if 5 square meters per minute is 1 and if 7 square meters per minute is 0.7, the optimal timing according to the air volume Drainage control can be performed.
次亜塩素酸の揮発量における温度と風量の影響であるが、これらの2つの事象はそれぞれ独立して起きているものと考えられ、両方の情報が得られる場合には、これらの二つの影響を乗じた値で設定するとより精度を高めることができ、好ましい。   The effects of temperature and air flow on the amount of volatilized hypochlorous acid are considered to be independent of each of these two events, and when both information can be obtained, these two effects Setting by a value obtained by multiplying can be more accurate, which is preferable.
(実施の形態2)
実施の形態1の揮発装置では、温度センサ15を吸気口2の周辺に配し、検知した室内空気の温度に基づいて、トレイ6の次亜塩素酸の揮発量を推定していた。本実施の形態ではそれに替えて、トレイ6の次亜塩素酸水溶液の次亜塩素酸濃度の低下を推定する方法として、図7に示すように、次亜塩素酸検知手段である次亜塩素酸水センサ16を用いることもできる。次亜塩素酸水センサ16は、次亜塩素酸の物性に基づいて連続的かつ特異的に検出できる方法がよく、紫外式、電気化学式などが知られている。次亜塩素酸は、水素イオン濃度に応じた解離特性により、非解離型の次亜塩素酸(HOCl)と、解離型の次亜塩素酸イオン(OCl−)に分かれて平衡状態で存在する。紫外式を用いると、それぞれ吸収波長が異なる特性を利用して、HOClは230nm、OCl−は294nmでそれぞれ検出することができる。このとき、揮発するのは非解離型のHOClであるため、このHOCl濃度を測定することで、揮発させるための次亜塩素酸の濃度が減少していることを精度よく推定できる。尚、このような次亜塩素酸水センサ16で定期的、あるいは連続的に読み取った次亜塩素酸濃度が、あらかじめ設定した下限閾値を下回ったことを判断して給排水制御を実行させる。
Second Embodiment
In the volatilizer of the first embodiment, the temperature sensor 15 is disposed around the inlet 2, and the volatilized amount of hypochlorous acid in the tray 6 is estimated based on the detected temperature of the indoor air. In the present embodiment, instead of this, hypochlorous acid, which is a means for detecting hypochlorous acid, as shown in FIG. 7 as a method for estimating the decrease in the concentration of hypochlorous acid in the aqueous solution of hypochlorous acid in tray 6. A water sensor 16 can also be used. The hypochlorous acid water sensor 16 is preferably a method capable of detecting continuously and specifically based on the physical properties of hypochlorous acid, and an ultraviolet type, an electrochemical type, etc. are known. Hypochlorous acid is divided into non-dissociative hypochlorous acid (HOCl) and dissociative hypochlorite ion (OCl-) and exists in an equilibrium state according to the dissociative characteristics according to the hydrogen ion concentration. Using an ultraviolet type, HOCl can be detected at 230 nm and OCl- can be detected at 294 nm, respectively, by utilizing the characteristics of different absorption wavelengths. At this time, since it is the non-dissociated HOCl that volatilizes, it is possible to accurately estimate that the concentration of hypochlorous acid for volatilization has decreased by measuring the HOCl concentration. In addition, it is judged that the hypochlorous acid concentration read regularly or continuously by such a hypochlorous acid water sensor 16 has fallen below the lower limit threshold value set beforehand, and water supply / drainage control is performed.
図8に次亜塩素酸水センサ16の構造を示す。紫外線光源17(例えば紫外線ランプ)と、紫外線を検知可能な受光素子18(例えばフォトダイオードなど)の間隙に、トレイ6の次亜塩素酸水溶液を保持、通水させ、水による紫外線の減衰を受光素子で検出し、ランベルト・ベールの法則に従って濃度に換算する。   The structure of the hypochlorous acid water sensor 16 is shown in FIG. The hypochlorous acid aqueous solution of the tray 6 is held in the gap between the ultraviolet light source 17 (for example, an ultraviolet lamp) and the light receiving element 18 (for example, a photodiode or the like) capable of detecting ultraviolet light. The element is detected and converted to concentration according to Lambert-Beer's law.
通水させる測定セル21は、紫外線の吸収をもたない素材である必要があり、石英ガラス19を用いる。紫外線光源17から受光素子18までの距離が変動しないよう、紫外線光源17と受光素子18は基板20に固定して使用する。   The measurement cell 21 to be supplied with water needs to be a material that does not have absorption of ultraviolet light, and quartz glass 19 is used. The ultraviolet light source 17 and the light receiving element 18 are fixed to the substrate 20 so that the distance from the ultraviolet light source 17 to the light receiving element 18 does not change.
本実施の形態の次亜塩素酸水溶液は微酸性電解水(HOCl)であり、これを測定するためには、次亜塩素酸への吸収の大きい波長の紫外線光源用意することが重要である。次亜塩素酸水溶液は230nmの紫外線を吸収しやすいという特性を持つため、この波長域に輝線を持つ紫外線ランプやハロゲンランプを使用し、バンドパス型の干渉フィルターを使用して所定の波長を取り出すことができる。あるいは、この波長に特異的な発光特性を持つ紫外線LEDを使用すると干渉フィルターが不要となり、センサを小型化できる。   The hypochlorous acid aqueous solution according to the present embodiment is slightly acidic electrolyzed water (HOCl), and in order to measure this, it is important to prepare an ultraviolet light source having a wavelength with large absorption to hypochlorous acid. Since the aqueous solution of hypochlorous acid has a characteristic of easily absorbing 230 nm ultraviolet light, an ultraviolet lamp or a halogen lamp having an emission line in this wavelength range is used, and a predetermined wavelength is extracted using a bandpass interference filter. be able to. Alternatively, if an ultraviolet LED having a light emission characteristic specific to this wavelength is used, the interference filter becomes unnecessary and the sensor can be miniaturized.
これにより次亜塩素酸水溶液の濃度低下にも素早く対処することができ、次亜塩素酸を安定して空間内に揮発させることで、結果として除菌、脱臭性能を高めた通風式の揮発装置を提供することができる。   As a result, the concentration decrease of the aqueous solution of hypochlorous acid can be quickly coped with, and by ventilating the hypochlorous acid stably in the space, a ventilated volatilizer with enhanced sterilization and deodorizing performance as a result Can be provided.
以上のように、本実施例によれば、除菌、脱臭性能を高めることができる揮発装置を簡単な構成で提供することができる。   As mentioned above, according to the present Example, the volatilization apparatus which can improve microbe elimination and deodorizing performance can be provided by easy structure.
家庭用や事務用、公共空間などの、除菌・脱臭などの空間浄化を行うための揮発装置としての活用が期待されるものである。   It is expected to be used as a volatilizer to clean up the space, such as sterilization and deodorization, for household use, office work, public space, etc.
