There are two types of usage of this slightly acidic hypochlorous acid water: spraying a mist of slightly acidic electrolyzed water into the air to purify the air, and use of slightly acidic electrolyzed water for washing hands and food. There is a device for each application. These apparatuses include a type that has a built-in means for generating slightly acidic electrolyzed water and a type that replenishes slightly acidic electrolyzed water from the outside.

しかし、従来のタイプの機器は、機器内で生成する微酸性電解水を他の機器に融通することはできなかった。このため、例えば、微酸性電解水の生成能力を有する空気浄化装置を大きな容量の部屋に設置し、微酸性電解水の生成能力のない空気浄化器を小さい容量の部屋に設置し、空気浄化装置で生成した微酸性電解水を空気浄化器に与えるといった使用形態を実現できなかった。   However, in the conventional type device, the slightly acidic electrolyzed water generated in the device could not be accommodated in other devices.

噴霧装置５３は通気路５２を流れる除菌対象空気に微酸性電解水を原液とする殺菌剤溶液を噴霧するもので、除菌対象空気５１の流れ方向の下流側に向けた複数の噴霧ノズル５３１を備えている。   The spraying device 53 sprays a sterilizing agent solution having a slightly acidic electrolyzed water as a stock solution on the sterilization target air flowing through the air passage 52, and a plurality of spray nozzles 531 directed downstream in the flow direction of the sterilization target air 51. It has.

微酸性電解水は、「微酸性次亜塩素酸水」の名称で食品添加物の殺菌剤に指定された電解水である。この微酸性次亜塩素酸水の定義は、「食品、添加物等の規格基準（昭和３４年１２月２８日厚生省告示第３７０号）」および「平成２４年０４月２６日厚生労働省告示第３４５号」によれば、塩酸又は塩酸に塩化ナトリウム水溶液を加えて適切な濃度に調整した水溶液を無隔膜電解槽（隔膜で隔てられていない陽極及び陰極で構成されたものをいう。）内で電解して得られる水溶液であって、主な有効成分が次亜塩素酸（ＨＣＬＯ）であり、ｐＨ５．０−６．５、有効塩素濃度１０−８０ｍｇ／ｋｇである。   Slightly acidic electrolyzed water is electrolyzed water designated as a food additive disinfectant under the name of “slightly acidic hypochlorous acid water”.

It is made into a mat shape having a thickness of about 10 to 50 mm by being concentrated or irregularly densely packed.

以下、上記した構成の作用を説明する。
（薬剤生成）
薬剤供給装置５６は、開閉バルブ５６３ａを開放した状態で原料供給系５６３を通して薬品搬入容器５６２から原料薬液の塩酸水を生成装置５６１に供給するとともに、給水系５６５から生成装置５６１に減圧弁５６４を介して希釈用の水を供給し、生成装置５６１において２−２１％塩酸水を被電解液とする。 The drainage system 545 communicates with a drainage tank 551, and the drainage tank 551 communicates with an external drainage system 553 with a drainage pump 552 interposed therebetween.
The operation of the above configuration will be described below.
(Drug production)
The chemical supply device 56 supplies the raw chemical solution hydrochloric acid from the chemical carry-in container 562 to the generation device 561 through the raw material supply system 563 with the opening / closing valve 563a opened, and a pressure reducing valve 564 from the water supply system 565 to the generation device 561. Then, water for dilution is supplied, and in the generating device 561, 2-21% hydrochloric acid is used as the electrolyte.

そして、生成装置５６１において被電解液を電解して微酸性電解水を生成し、微酸性電解水を供給ポンプ５６７により薬剤供給系５７６を通して中継槽５６６に供給し、さらに中継ポンプ５６９により中継系５７０を介して中継槽５６６から循環槽５４へ微酸性電解水を供給する。
（運転時）
薬剤供給装置５６は、中継槽５６６から循環槽５４へ微酸性電解水を供給しつつ、希釈水制御バルブ５７２を開放する状態で流量調整弁５７３を通して希釈水を循環槽５４に供給し、循環槽５４の殺菌剤溶液の有効塩素濃度を０．１−１０ｍｇ／Ｌに維持する。 The generating device 561 electrolyzes the electrolytic solution to generate slightly acidic electrolyzed water, and the slightly acidic electrolyzed water is supplied to the relay tank 566 through the drug supply system 576 by the supply pump 567 and further to the relay system 570 by the relay pump 569. Then, slightly acidic electrolyzed water is supplied from the relay tank 566 to the circulation tank 54.
(During driving)
The medicine supply device 56 supplies the diluted water to the circulation tank 54 through the flow rate adjustment valve 573 while opening the dilution water control valve 572 while supplying the slightly acidic electrolyzed water from the relay tank 566 to the circulation tank 54. The effective chlorine concentration of 54 germicide solution is maintained at 0.1-10 mg / L.

この状態で、ハウジング５０の通気路５２を上流側から下流側に流れる除菌対象空気５１に、噴霧装置５３の噴霧ノズル５４１から循環槽５４で濃度調整された殺菌剤溶液を噴霧する。   In this state, the sterilizing agent solution whose concentration is adjusted in the circulation tank 54 is sprayed from the spray nozzle 541 of the spraying device 53 to the sterilization target air 51 flowing from the upstream side to the downstream side through the air passage 52 of the housing 50.

この噴霧により、除菌対象空気５１に含まれる浮遊菌や塵埃は、噴霧された殺菌剤溶液の噴霧水に衝突し、捕捉される。さらにメディアに到達した噴霧水は、メディアを流下し水膜を形成するとともに、空気に触れて蒸発し、空気を加湿する。また、噴霧水はメディアに付着した浮遊菌や塵埃を流下させるとともに、空気中の浮遊菌や塵埃を取り込み、循環槽５４内に流入する。   By this spraying, floating bacteria and dust contained in the sterilization target air 51 collide with the spray water of the sprayed disinfectant solution and captured. Further, the spray water that has reached the medium flows down the medium to form a water film, and evaporates by touching the air to humidify the air. In addition, the sprayed water causes the floating bacteria and dust attached to the medium to flow down, takes in the floating bacteria and dust in the air, and flows into the circulation tank 54.

このように、微酸性電解水を原液とし、それを希釈した殺菌剤溶液を除菌対象空気５１に直接に噴霧することで、微酸性電解水の主成分である次亜塩素酸（ＨＣＬＯ）の殺菌力の強さ、反応性の高さを利用して空気中の菌を除菌することができる。除菌エレメントに滴下するのではなく、空気中に殺菌剤溶液を高い飽和効率で噴霧するので、空気中の浮遊菌や塵埃を殺菌剤溶液に取り込むことができ、除菌に加えて除塵も実現できる。   In this way, by using a slightly acidic electrolyzed water as a stock solution and directly spraying a diluted bactericide solution onto the air 51 to be sterilized, hypochlorous acid (HCLO), which is the main component of the slightly acidic electrolyzed water, is obtained. Bacteria in the air can be sterilized using the strength of sterilization power and high reactivity. Rather than dripping on the disinfecting element, spraying the disinfectant solution into the air with high saturation efficiency allows airborne germs and dust to be taken into the disinfectant solution, and in addition to disinfecting, dust removal is also realized. it can.

噴霧装置５３から噴霧した殺菌剤溶液は、一部が通気路５２から循環槽５４に降下し、他のものがメディア５０３に達して後にメディア５０３を伝って循環槽５４に流れる。循環槽５４は通気路５２から降下する殺菌剤溶液およびメディア５０３から流れ落ちる殺菌剤溶液を受け止める。   Part of the disinfectant solution sprayed from the spraying device 53 descends from the air passage 52 to the circulation tank 54, and the other reaches the medium 503 and then flows through the medium 503 to the circulation tank 54. The circulation tank 54 receives the sterilizing agent solution descending from the air passage 52 and the sterilizing agent solution flowing down from the medium 503.

メディア５０３を通過した殺菌後の空気は、ミストセパレータ５０４および中性能フィルター５０５を通過してファン装置５０６により室内へ供給される。
（微酸性電解水の取り出し）
空気清浄装置から微酸性電解水を取り出す場合には、三方切替弁５７８を操作して薬剤供給装置５６の薬剤供給系５７６を外部取出部５７９に接続し、微酸性電解水を供給ポンプ５６７により薬剤供給系５７６を通して給水口５８０から取り出す。 The sterilized air that has passed through the medium 503 passes through the mist separator 504 and the medium performance filter 505 and is supplied into the room by the fan device 506.
(Removal of slightly acidic electrolyzed water)
When the slightly acidic electrolyzed water is taken out from the air cleaning device, the three-way switching valve 578 is operated to connect the drug supply system 576 of the drug supply device 56 to the external extraction unit 579, and the slightly acidic electrolyzed water is supplied to the drug by the supply pump 567. It is taken out from the water supply port 580 through the supply system 576.

この場合、中継槽５６６から循環槽５４へ微酸性電解水を供給することで、微酸性電解水の取出中においても、空気浄化の運転は継続して行うことができる。そして、微酸性電解水の取り出し中に中継槽５６６の液位計５６６ａで計測する水位が下限水位以下になった場合には、三方切替弁５７８を操作して薬剤供給装置５６の薬剤供給系５７６を中継槽５６６に切り替えて微酸性電解水を中継槽５６６に供給する。   In this case, by supplying the slightly acidic electrolyzed water from the relay tank 566 to the circulation tank 54, the air purification operation can be continuously performed even during the extraction of the slightly acidic electrolyzed water. Then, when the water level measured by the liquid level gauge 566a of the relay tank 566 becomes equal to or lower than the lower limit water level during taking out the slightly acidic electrolyzed water, the three-way switching valve 578 is operated to operate the medicine supply system 576 of the medicine supply device 56. Is switched to the relay tank 566, and slightly acidic electrolyzed water is supplied to the relay tank 566.

本実施の形態では、外部取出部５７９を薬剤供給系５７６から分岐させたが、外部取出部５７９を中継槽５６６に接続させることも可能であり、この場合には外部取出部５７９にバルブ等を設ける。   In the present embodiment, the external extraction unit 579 is branched from the medicine supply system 576. However, the external extraction unit 579 can be connected to the relay tank 566, and in this case, a valve or the like is connected to the external extraction unit 579. Provide.

この構成では、中継槽５６６の水位を常に高水位に維持するために、中継槽５６６における下限水位を高水位に設定し、下限水位と上限水位の間隔を小さくして水位制御する。そして、微酸性電解水の取り出し中に中継槽５６６の液位計５６６ａで計測する水位が下限水位以下になった場合には、外部取出部５７９のバルブを自動的に閉栓操作する。   In this configuration, in order to always maintain the water level of the relay tank 566 at a high water level, the lower limit water level in the relay tank 566 is set to a high water level, and the water level is controlled by reducing the interval between the lower limit water level and the upper limit water level. When the water level measured by the liquid level gauge 566a in the relay tank 566 becomes equal to or lower than the lower limit water level during the extraction of the slightly acidic electrolyzed water, the valve of the external extraction unit 579 is automatically closed.

上記実施の形態では空気浄化装置について説明したが、本発明は空気調和機にも適用することができる。
例えば、図３に示すように、中性能フィルター５０５の下流側に湿度調整部および温度調整部をなす冷却コイル５０７と加熱コイル５０８を配置する。この構成により、湿度調整部をなす噴霧装置５３から噴霧する殺菌剤溶液による加湿、冷却コイル５０７による除湿および減温、加熱コイルによる加温により、除菌後の空気の湿度、温度を適宜に調整する。他の作用効果については先の実施の形態と同様であり、同符号を付して説明を省略する。 Although the air purification apparatus has been described in the above embodiment, the present invention can also be applied to an air conditioner.
For example, as shown in FIG. 3, a cooling coil 507 and a heating coil 508 that form a humidity adjustment unit and a temperature adjustment unit are arranged on the downstream side of the medium performance filter 505. With this configuration, the humidity and temperature of the air after sterilization are appropriately adjusted by humidification with the bactericide solution sprayed from the spray device 53 constituting the humidity adjustment unit, dehumidification and temperature reduction by the cooling coil 507, and heating by the heating coil. To do. Other operational effects are the same as those of the previous embodiment, and the same reference numerals are given and description thereof is omitted.
