【0018】
【実施例】
以下、本発明の実施例について図面を用いて説明する。
【0019】
(実施例1)
本実施例においては、流し台の排水口の殺菌、脱臭及び異物除去についての一例について説明する。
【0020】
図1は本発明の実施例1の殺菌装置の構成図、図2は同殺菌装置をキッチンの流し台の殺菌に用いた場合の模式図である。
【0021】
図1、図2において、8は殺菌装置で、内部には電極9、10を備えた電解手段としての電解槽11と、電解槽11に塩素イオンを供給する塩素供給手段、この実施例では、内部に食塩水を蓄えた食塩タンク12と、食塩タンク12と電解槽11を結ぶ食塩流路13と、この食塩流路13を介して食塩水を電解槽11に送り込む食塩ポンプ14を備えている。また、搬送手段として、水道配管と間接的または直接的に接続された水道水の流路15と、水道水の流入出を制御する弁16を有している。そして、異物除去手段は、内部に界面活性剤として台所用中性洗剤を蓄えた洗剤タンク17と、洗剤タンク17と流路15を連結している洗剤流路18を備え、この洗剤流路18上には界面活性剤タンク17内の洗剤タンク17内の台所用中性洗剤を流路15に送り込むための洗剤ポンプ19を配置している。電解槽11で生成した電解水は、流路15の末端部20から排出される。そして、電解槽11と流路15は流路21、22で接続されており、弁16を開くことで水道水が流路15から流路20を通過して電解槽11に入り、流路22を通って再び流路15に入る水回路を形成している。
【0022】
さらに、電解槽11内の電極9、10への通電、弁16、食塩ポンプ14、洗剤ポンプ19の動作制御は、制御手段としての制御装置23で行っている。
【0023】
また、図2は殺菌装置8を流し台24に設置した配置例を示す図であり、流し台24はシンク部25とワークトップ部26と、カラン27とを有し、シンク部25には、排水口28と、この排水口28にトラップ部29を有し、このトラップ部29内に生ゴミなどを受けるバスケット30を備え、トラップ部29の下側は排水路31が接続されており、本実施例ではこれらを排水部32とよぶ。
【0024】
次に動作、作用について説明する。本実施例では排水部32(流し台の排水口28、バスケット30、トラップ29、排水路31)の殺菌、脱臭及び異物除去を行う例について説明する。
【0025】
使用者が食器の洗浄、調理などを終了した後に以下の動作が行われるように予め制御装置23に動作を行う時間帯を記憶させておく。好ましくは、深夜(0:00〜5:00までの間)に動作を行うように設定しておく。
【0026】
設定した時間がきたら、制御装置23で弁16を開き、殺菌装置8内に水道水を送り込み、流路15及び流路21を介して電解槽11内に水道水を注入する。制御装置23内の所定時間経過後に弁16を閉じ、食塩ポンプ14を始動し、食塩タンク12内の食塩水を、電解槽11内の塩素イオン濃度が所定濃度になるように送り込む。その後、制御手段23により電極9、10に通電を行い、電解槽11内に電気分解により次亜塩素酸化合物などの酸化性物質を含む電解水を生成する。この時、電極9、10は定期的に極性を切り替え、電極9、10表面にスケール成分が付着するのを防止している。電極9、10への通電を所定時間行い、電解槽11内に十分な濃度の電解水が生成できれば、排水部32の殺菌準備が可能となる。
【0027】
排水部32の殺菌、脱臭を行う場合には、制御装置23で弁16を開き、流路15と流路21を介して電解槽11に水道水を送り込む。この水道水を介して電解槽11内で生成した電解水は流路22から再び流路15に送り込まれ、流路15を通過した水道水と混ぜられ、流路末端部20から排出され、排水部32に到達する。流路末端部20から電解水を排出し、電解水を排水口28、トラップ29、排水路31の表面およびバスケット30の内側、外側と内部にある残飯、残菜などの生ゴミと接触させる。これによりこれらに繁殖する細菌、カビなどの微生物を殺菌することができるので、微生物の繁殖によるニオイの発生やヌメリ(バイオフィルム)の発生を抑制することができる。
【0028】
しかし、生ゴミに油脂成分が含まれていたり、シンク25に流す排水の中にたとえばドレッシング、食用油等の油脂成分を含むものが混ざっている場合がある。このような場合には電解水と排水が混ざり合うと、電解水中のアルカリや次亜塩素酸化合物と反応し、ケン化物を生成しやすい環境となるので、時間と共に徐々にケン化反応が進み、排水部32の至るところに白色異物が発生する。また、電解水と反応しなくても、油脂の量が多い場合には時間と共にトラップ29、バスケット30排水路31等に徐々に固形化物が発生し、外観を損なうと同時に、これらの部分を触ると違和感があり、不快感を覚える人が多い。この現象がさらに進行すると、排水路31が詰まる恐れがある。
【0029】
そこで、電解水で処理した後に、洗剤ポンプ19を動作させ、所定量の中性洗剤を流路15に送り込み、水道水を介して流路末端部20から排出し、排水部32に接触させる。この動作によって、排水部32に付着した油脂成分が電解水中のアルカリ成分や次亜塩素酸化合物と反応し、白色異物として排水部32に付着する前に油脂成分を除去できるので、外観を損なったり、排水路31が詰まってしまうことがなく、使用者がこの部分を掃除する際に触っても違和感を感じることが無い。
【0030】
以上の動作を定期的に行うことで細菌の増殖が常に阻害される。よって排水部32のニオイ、ヌメリ(バイオフィルム)の発生やケン化物などの異物の発生がない清浄な排水部32を維持することができる。また、排水部32で増殖する細菌は中温領域(20℃〜35℃前後)を好む細菌が繁殖しており、室温でも3日〜5日で指で触るとヌメリをはっきり感じるほど活発にバイオフィルムを生成し、はっきりとした腐敗臭(ニオイ)もする。そこで、好ましくは少なくとも5日以内に1回、上述の殺菌処理を行うことで、バイオフィルム、ニオイが少ない状態に保つことができる。
【0031】
図3に排水部32に繁殖する細菌の増殖特性を示した。図3示したように、排水部32に繁殖する細菌は1日後から活発に増殖を開始し、3日から5日にかけて菌数が安定する。細菌数とヌメリ(バイオフィルム)、ニオイとは相関関係があり、菌数が多いとニオイ、ヌメリの官能値も高くなる。従って、増殖が活発に開始する前の時点、すなわち、24時間以内に殺菌処理を行うと細菌数は常に低いレベル(10CFU/cmレベル以下)となり、ヌメリ、ニオイがほとんどないレベルに維持することができる。さらに、これと同時に、洗剤タンク17から洗剤を排水部32に供給することで、表面の油脂などを除去させるので、細菌の栄養源も除去され、細菌の増殖抑制効果を期待できる。なお、洗剤を供給することで油脂が除去されるので排水部32の表面にケン化物などの異物が発生することがなくなり、外観を損なうこともなく、排水路31が詰まることがない。
【0032】
なお、電解水の供給及び洗剤の供給は1日に1回以上、好ましくは3回行うことでニオイ及びヌメリの抑制効果を向上させることができる。ちなみに、電解水及び洗剤を1日2回以上添加した場合には細菌の増殖によるニオイやヌメリの発生は無かった。
【0033】
また、濃度に関しては、表1に示したように、30ppm〜10、000ppmまでの間で効果が確認できた。しかし、10、000ppmでは殺菌中に流し台24の近くにいるとはっきりと塩素臭を感じ、塩素臭が嫌いな人は違和感を感じる。一方、30ppmでは細菌が増加し、腐敗臭やバイオフィルムを発生する。そこで、供給する電解水の濃度を30ppm〜1000ppmに維持する。これにより、腐敗臭やバイオフィルムを発生を抑制すると同時に塩素臭を低いレベルに押さえることができる。
【0034】
【表1】

【0035】
また、この実施例では排水部32に異物が付着しないように洗剤タンク17から洗剤を注入する構成としているが、以下に洗剤の注入のタイミングについて説明する。
【0036】
食器を洗ったり、調理後には排水部32には常に油脂が存在している。この様な状態のところに電解槽11から電解水を供給すると直ちに反応し、ケン化物を生成する。このケン化物は洗剤を供給することによりほとんど剥離除去できるが、若干残留する場合がある。この様なことを想定し、制御装置23により、電解槽11の電極9.10に通電を行う前に、弁16を開き、水道水を排水部32に供給し、予め、油脂を除去する。これにより排水部32に残留する油脂の量を減少することができ、結果として電解水を注入した時もケン化物の生成が少なくなるので、残留するケン化物も少なくなる。なお、このとき水道水だけを供給するのでなく、洗剤タンク17から洗剤を同時に供給することで、油脂の除去効果がまし、ケン化物の残留をほとんどなくすことができる。
【0037】
さらに、排水部32のトラップ29内のバスケット30に肉等の油を含むものが存在すると、ここから油を含む汁がトラップ29におちる。排水部32の殺菌中に油を含む汁がトラップ29に落ちると、電解水と反応し、ケン化物が生成し、壁面に異物を発生する。そこで、排水部32を電解水で処理した後、洗剤タンク17から洗剤を供給する必要がある。この動作により、仮に電解水で処理している間に油を含む汁がトラップ29内に入り、ケン化物が生成した場合でも、洗剤で直ちに剥離除去できるので、ケン化物が壁面に強固に付着することが無くなり、排水部32を常に清浄な状態に保つことができる。
【0038】
なお、電解槽11で電気分解により電解水を生成後、電解水を流路15から排水部32に供給する際に、流路15に洗剤タンク17から洗剤を送り込み、排水部32に電解水と洗剤を供給すると、トラップ29部分に幾分かの水が滞留することになる。このとき、トラップ29内には電解水と洗剤が共存することとなり、トラップ29の表面に存在する油脂は洗剤の界面活性作用により剥離され、トラップ29に溜まった水にコロイド状で存在するので、電解水と油脂が反応しても水中にケン化物が生成されるのでケン化物のトラップ29への付着はない。従って、トラップ29への白色異物の付着を効果的に除去することができる。さらに、電解水がトラップ29の水溜りに滞留している間は、洗剤も滞留することとなるので、洗剤の油脂またはケン化物との反応時間を稼ぐことができ、油脂ならびにケン化物の剥離効果を向上させることができる。
【0039】
また、トラップ29のように水溜りが幾分か形成される場合は良いが、バスケット部30のように電解水が供給されると壁面をたどって流れ落ちる個所が存在する。この様な場合には電解水の供給路と洗剤の供給路を同一とすることで電解水と接触した場所とほぼ同一の場所に洗剤を供給できる。すなわち、電解水だけが接触し、洗剤が接触しない場所が存在するとケン化物が生成され、異物として残留したり、逆に、洗剤だけが接触した場所はバイオフィルムが発生したりするので、同一個所に電解水と洗剤を接触させることは必須であり、この様な構成とすることで、異物の残留とバイオフィルムの発生を抑制できる。
【0040】
【発明の効果】
以上説明したように本発明の請求項1に係る殺菌装置によれば、殺菌性物質と異物除去性物質を一定時間毎に供給するので、細菌の増殖を確実効果的に抑制することができると同時に、油脂または、油脂とアルカリが反応して生成したケン化物を確実に除去することができ、固形化した油脂やケン化物が固体表面に付着し、油臭がしたり、外観を損なうことが無く、排水口の詰まりをなくすことができるという効果がある

The sink portion 25 includes a drain outlet. 28, a trap portion 29 at the drain port 28, a basket 30 for receiving garbage etc. is provided in the trap portion 29, and a drainage channel 31 is connected to the lower side of the trap portion 29. These are called the drainage part 32.
[0024]
Next, the operation and action will be described. In this embodiment, an example will be described in which the drainage section 32 (the sink outlet 28, the basket 30, the trap 29, and the drainage channel 31) is sterilized, deodorized, and foreign matter removed.
[0025]
A time zone during which the operation is performed is stored in advance in the control device 23 so that the following operation is performed after the user finishes washing the dishes and cooking. Preferably, the operation is set to be performed at midnight (between 0:00 and 5:00).
[0026]
When the set time comes, the valve 16 is opened by the control device 23, tap water is sent into the sterilizer 8, and tap water is injected into the electrolytic cell 11 through the flow path 15 and the flow path 21. After a predetermined time in the control device 23 has elapsed, the valve 16 is closed, the salt pump 14 is started, and the salt water in the salt tank 12 is fed so that the chlorine ion concentration in the electrolytic cell 11 becomes a predetermined concentration. Thereafter, the electrodes 9 and 10 are energized by the control means 23, and electrolyzed water containing an oxidizing substance such as a hypochlorous acid compound is generated in the electrolytic cell 11 by electrolysis. At this time, the electrodes 9 and 10 are periodically switched in polarity to prevent the scale components from adhering to the surfaces of the electrodes 9 and 10. If the electrodes 9 and 10 are energized for a predetermined time and electrolyzed water having a sufficient concentration can be generated in the electrolyzer 11, the drainage section 32 can be prepared for sterilization.
[0027]
When performing sterilization and deodorization of the drainage section 32, the valve 16 is opened by the control device 23, and tap water is fed into the electrolytic cell 11 through the flow path 15 and the flow path 21. The electrolyzed water generated in the electrolytic cell 11 through the tap water is sent again from the flow path 22 to the flow path 15, mixed with the tap water that has passed through the flow path 15, discharged from the flow path end 20, and drained. The unit 32 is reached. Electrolyzed water is discharged from the channel end 20 and the electrolyzed water is brought into contact with the waste outlets 28, the traps 29, the surface of the drainage channel 31, and the inside, outside and inside of the basket 30, and raw garbage such as leftovers and leftovers. This makes it possible to sterilize microorganisms such as bacteria and molds that propagate in these, so that the generation of odor and the occurrence of slime (biofilm) due to the propagation of microorganisms can be suppressed.
[0028]
However, there are cases where fats and oils components are contained in the raw garbage, or wastewater flowing into the sink 25 is mixed with oils and fats components such as dressing and cooking oil. In such a case, when the electrolyzed water and the wastewater are mixed, it reacts with the alkali or hypochlorous acid compound in the electrolyzed water, and it becomes an environment where saponified products are easily generated. White foreign matter is generated throughout the drainage section 32. Even if it does not react with the electrolyzed water, if the amount of fats and oils is large, solidified substances are gradually generated in the trap 29, the basket 30 drainage channel 31 and the like with time, and the appearance is impaired, and at the same time, these parts are touched. Many people feel uncomfortable and feel uncomfortable. If this phenomenon further proceeds, the drainage channel 31 may be clogged.
[0029]
Then, after processing with electrolyzed water, the detergent pump 19 is operated, a predetermined amount of neutral detergent is sent to the flow path 15, discharged from the flow path end 20 through the tap water, and brought into contact with the drainage section 32. By this operation, the oil and fat component adhering to the drainage portion 32 reacts with the alkaline component and hypochlorous acid compound in the electrolyzed water, and the oil and fat component can be removed before adhering to the drainage portion 32 as a white foreign matter. The drainage channel 31 is not clogged and the user does not feel uncomfortable even when touching this part when cleaning it.
[0030]
By regularly performing the above operations, the growth of bacteria is always inhibited. Therefore, it is possible to maintain a clean drainage portion 32 that is free from odor and slime (biofilm) of the drainage portion 32 and foreign matter such as saponified substances. In addition, the bacteria that grow in the drainage section 32 are those that prefer the medium temperature range (around 20 ° C to 35 ° C), and the biofilm is active enough to feel the slime clearly when touched with a finger at room temperature for 3-5 days. With a clear odor. Therefore, the biofilm and odor can be kept low by performing the above-described sterilization treatment preferably at least once within 5 days.
[0031]
FIG. 3 shows the growth characteristics of bacteria that propagate in the drainage section 32. As shown in FIG. 3, the bacteria that proliferate in the drainage section 32 actively start to grow after 1 day, and the number of bacteria is stabilized from 3 days to 5 days. There is a correlation between the number of bacteria, slime (biofilm), and odor, and the higher the number of bacteria, the higher the sensory value of odor and slime. Therefore, when the sterilization treatment is carried out within 24 hours before the start of active growth, that is, the number of bacteria is always at a low level (10 3 CFU / cm 2 level or less), and is maintained at a level with almost no slime and odor. can do. Furthermore, at the same time, the detergent is supplied from the detergent tank 17 to the drainage section 32, so that the oils and fats on the surface are removed. Therefore, the nutrient source of bacteria is also removed, and the effect of inhibiting the growth of bacteria can be expected. In addition, since fats and oils are removed by supplying the detergent, foreign matters such as saponified substances are not generated on the surface of the drainage portion 32, the appearance is not impaired, and the drainage channel 31 is not clogged.
[0032]
In addition, the suppression effect of odor and slime can be improved by supplying electrolytic water and detergent one time or more, preferably three times a day. By the way, when electrolyzed water and detergent were added twice or more a day, there was no generation of odor or slime due to bacterial growth.
[0033]
Moreover, regarding the concentration, as shown in Table 1, the effect could be confirmed between 30 ppm and 10,000 ppm. However, at 10,000 ppm, if you are near the sink 24 during sterilization, you will clearly feel a chlorine odor, and those who dislike the chlorine odor will feel uncomfortable. On the other hand, at 30 ppm, bacteria increase and a spoiled odor or biofilm is generated. Therefore, the concentration of the supplied electrolyzed water is maintained at 30 ppm to 1000 ppm. Thereby, generation | occurrence | production of a decaying odor and a biofilm can be suppressed, and simultaneously a chlorine odor can be suppressed to a low level.
[0034]

[0035]
Further, in this embodiment, the detergent is injected from the detergent tank 17 so that foreign matter does not adhere to the drainage section 32. The timing of the detergent injection will be described below.
[0036]
Oil is always present in the drainage part 32 after washing dishes or cooking. When electrolyzed water is supplied from the electrolytic cell 11 to such a state, it reacts immediately to produce a saponified product. This saponified product can be almost peeled and removed by supplying a detergent, but may remain slightly. Assuming this, the control device 23 opens the valve 16 and supplies tap water to the drainage part 32 before energizing the electrode 9.10 of the electrolytic cell 11 to remove oil and fat in advance. As a result, the amount of oil and fat remaining in the drainage part 32 can be reduced, and as a result, even when electrolyzed water is injected, the generation of saponified products is reduced, so that the amount of residual saponified products is also reduced. At this time, not only supplying tap water but also supplying detergent from the detergent tank 17 at the same time improves the effect of removing oils and fats, and the saponification residue can be almost eliminated.
[0037]
Furthermore, if the basket 30 in the trap 29 of the drainage part 32 contains oil such as meat, the juice containing the oil falls into the trap 29 from here. When the juice containing oil falls into the trap 29 during the sterilization of the drainage part 32, it reacts with the electrolyzed water to produce a saponified product and generate foreign matter on the wall surface. Therefore, it is necessary to supply the detergent from the detergent tank 17 after the drainage section 32 is treated with electrolytic water. By this operation, even if the juice containing oil enters the trap 29 during the treatment with the electrolyzed water and saponification product is generated, the saponification product adheres firmly to the wall surface because the saponification product can be immediately peeled and removed by the detergent. The drainage part 32 can always be kept clean.
[0038]
In addition, when electrolyzed water is generated by electrolysis in the electrolytic cell 11, when supplying the electrolyzed water from the flow path 15 to the drainage section 32, the detergent is fed into the flowpath 15 from the detergent tank 17, and the drainage section 32 is fed with the electrolyzed water. When the detergent is supplied, some water stays in the trap 29 portion. At this time, the electrolyzed water and the detergent coexist in the trap 29, and the fats and oils existing on the surface of the trap 29 are peeled off by the surface active action of the detergent, and are present in the colloidal form in the water accumulated in the trap 29. Even if the electrolyzed water reacts with fats and oils, a saponified product is generated in the water, so that the saponified product does not adhere to the trap 29. Accordingly, it is possible to effectively remove the adhesion of white foreign matters to the trap 29. Further, while the electrolyzed water stays in the pool of the trap 29, the detergent also stays, so that the reaction time of the detergent with fats and oils or saponified products can be gained, and the fats and oils and saponified products can be removed. Can be improved.
[0039]
In addition, although some water pools may be formed as in the trap 29, there are places where the electrolytic water flows down along the wall surface when the electrolyzed water is supplied as in the basket portion 30. In such a case, the electrolytic water supply path and the detergent supply path are made the same so that the detergent can be supplied to almost the same place as the place in contact with the electrolytic water. That is, if there is a place where only the electrolyzed water is in contact and the detergent is not in contact, a saponified product is generated and remains as a foreign substance. It is essential to bring the electrolytic water and the detergent into contact with each other. By adopting such a configuration, it is possible to suppress the residue of foreign matter and the generation of biofilm.
[0040]
【The invention's effect】
As described above, according to the sterilization apparatus according to claim 1 of the present invention, since the bactericidal substance and the foreign substance removing substance are supplied at regular intervals, the growth of bacteria can be reliably and effectively suppressed. At the same time, the saponified product produced by the reaction of fats and oils or fats and alkalis can be removed reliably, and solidified fats and oils and saponified products can adhere to the solid surface, causing an oily odor and deteriorating the appearance. There is an effect that the clogging of the drainage port can be eliminated .
