Description

【0001】
【発明の属する技術分野】
本発明は、微生物の殺菌、特に一般家庭、調理関連業務のキッチン及び食品工場の微生物の殺菌、洗浄を行う殺菌装置に関するものである。
【0002】
【従来の技術】
従来のこの種の殺菌装置は特開平5−269182号公報に記載されているようなものが一般的であった。この殺菌装置は図5に示すように、流し台1に漂白洗浄を行う漂白槽2と、この内部に電気分解により次亜塩素酸化合物を生成可能な電解槽3を備え、洗浄槽4は排水口7を有し、ここで食事の残飯、残菜が捕捉され、これらの下流側への流出を押さえている。この排水口7の殺菌、脱臭を行う場合には、ツマミ6を回動させることで、コック5が切り替わり、排水口7に次亜塩素酸化合物が流れ込み、殺菌、脱臭可能としている。
【0003】
【発明が解決しようとする課題】
しかしながら上記従来の殺菌装置では、排水口7の殺菌はできるものの、残飯中には油脂成分も混入するので、この油脂と、電気分解で生成した次亜塩素酸化合物、または水酸化ナトリウムによりケン化物が生成したり、油脂が固形化するので、配管や、洗浄槽に付着し、油臭がしたり、排水口の水の通過が悪くなるなどの悪影響を及ぼす。
【0004】
【課題を解決するための手段】
本発明は上記課題を解決するため、流し台の排水口を殺菌するための殺菌装置であって、内部に電極を備えた電解槽を有する電解手段と、電解槽に塩素イオンを供給する塩素供給手段と、塩素供給手段と電解槽とを結ぶ流路と、界面活性剤を有する洗剤を蓄えるための洗剤タンクと、を備え、塩素供給手段から電解槽内に塩素イオンが送り込まれ、その後に電極に通電が行われ電解槽内において電気分解が行われることにより次亜塩素酸化合物又は水酸化ナトリウムを含む電解水が生成され、その後に排水口に電解水を供給し、その後に電解水の供給により発生するケン化物若しくは固形化した油脂を除去するために洗剤タンクから洗剤を前記排水口に送り込むものである。
【0005】
上記発明によれば殺菌手段により供給される殺菌性物質により殺菌を行い、異物除去手段でケン化物や固形化した油脂を除去可能な異物除去性物質を供給することで、殺菌ができると同時に異物の除去も可能となり、油臭や排水口の詰まりをなくすことができる。
【0006】
【発明の実施の形態】
本発明の請求項1にかかる殺菌装置は、流し台の排水口を殺菌するための殺菌装置であって、内部に電極を備えた電解槽を有する電解手段と、電解槽に塩素イオンを供給する塩素供給手段と、塩素供給手段と電解槽とを結ぶ流路と、界面活性剤を有する洗剤を蓄えるための洗剤タンクと、を備え、塩素供給手段から電解槽内に塩素イオンが送り込まれ、その後に電極に通電が行われ電解槽内において電気分解が行われることにより次亜塩素酸化合物又は水酸化ナトリウムを含む電解水が生成され、その後に排水口に電解水を供給し、その後に電解水の供給により発生するケン化物若しくは固形化した油脂を除去するために洗剤タンクから洗剤を前記排水口に送り込む
【0007】
そして、殺菌手段から供給される殺菌性物質により微生物の増殖を抑制すると同時に、異物除去手段により供給される異物除去性物質により油脂または、油脂とアルカリが反応して生成したケン化物を除去可能となるので、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。そして、界面活性剤により固体表面に付着した油脂を除去することで、電気分解により生成した次亜塩素酸化合物または水酸化ナトリウムと油脂が固体表面で反応することが無くなり、固体表面を清浄な状態に保つことができる
【0008】
【実施例】
下、本発明の実施例について図面を用いて説明する。
【0009】
(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。
【0010】
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。
【0011】
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としての洗剤タンク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を介して接続されており、弁16を開くことで水道水が流路15から流路21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。
【0012】
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。
【0013】
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。
【0014】
次に動作、作用について説明する。まず、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前に制御装置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、食塩ポンプを始動し、食塩タンク12内の食塩水を食塩ポンプ14で食塩流路13を介し、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。
【0015】
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。
【0016】
排水口28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とで、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。よって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。
【0017】
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、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。
【0018】
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。
【0019】
なお、本実施例では、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、水道水の流出入を制御する弁16を有する構成としているので、電解槽11内に生成した電解水を流路15に送り込んだ後または洗剤を洗剤ポンプ19で送り込んだ後に流路15に残留した電解水や洗剤は水道水で洗い流され、流路15に残らないので、流路15の電解水や洗剤による劣化を最小限にすることができると同時に、被処理物(本実施例では排水口28、トラップ29、バスケット30、排水路31)に電解水や洗剤が長時間残留することがなくなり、これらの素材の劣化を最小限にすることができる。
【0020】
また、本実施例では、電解槽11の電極9、10に通電を行い、電気分解により、電解水を生成しており、常に一定濃度の次亜塩素酸化合物を含む電解水を生成可能なので、薬剤のように長時間放置による濃度が低下がなく、次亜塩素酸化合物の濃度を一定に維持でき、殺菌、脱臭性能を安定させることができる。しかし、供給させる原水中の塩素イオン濃度が低い場合には電気分解で生成できる次亜塩素酸化合物の濃度が低くなり、十分な殺菌、脱臭能力を得ることができないが、塩素イオン供給手段として、食塩タンク12、食塩流路13、食塩ポンプ14を備え、電解槽11内の塩素イオン濃度を一定濃度以上にしているので、電極9、10間に流す電流量を一定にしていれば電気分解で生成させる電解水濃度を一定の濃度に維持することができ、安定した殺菌、脱臭能力を得ることができる。
【0021】
(実施例2)
図3は実施例2を示し、実施例1と異なる点は、洗剤タンク17、洗剤流路18、洗剤ポンプ19の代わりに油脂を分解する油脂分解剤として酵素のリパーゼを貯蔵する分解剤タンク33、分解剤ポンプ34、分解剤流路35を有し、酵素の働きで油脂を分解することで、排水部32に付着する油脂を除去し、ケン化物の発生と油脂の固形化を防止しているところにある。
【0022】
なお、実施例1と同一符号のものは同一構造を有し、説明は省略する。
【0023】
次に動作、作用を説明すると、電解水による排水部32の殺菌後、制御手段23により分解剤ポンプ34を始動し、分解剤タンク33内部のリパーゼを分解剤流路35から流路15に送り込み、流路末端20から排出し、排水部32に付着する油脂を除去し、ケン化物の発生と油脂の固形化を防止している。分解剤として酵素を用いることにより、界面活性剤を用いる場合よりも環境負荷を低減すると同時に、確実に油脂の除去を行うことができる。さらに、酵素を用いているので、油脂の分解反応が連続的に起こるので効果的な油脂の除去が可能となる。
【0024】
なお、本実施例では、分解剤としてリパーゼを用いたが、リパーゼのような酵素の他、たとえば、過炭酸ナトリウムのような弱アルカリや水酸化ナトリウムのような強アルカリを用いることで完全に油脂の除去が可能となる。
【0025】
(実施例3)
上記図3を用いて実施例3を説明する。実施例1と異なる点は、電極9、10間に隔膜36を有し、電解槽11の下流側に流路切換弁39と、流路40、41、42を有している点にある。そして、電解槽11で酸性の電解水を生成し、これを用いて排水部32の殺菌、脱臭を行う点にある。つまり、電極9、10の間に物質透過性を有する隔膜36が配置されている。そして、電解槽11の上流側には、電極9と隔膜36で形成される隔室Aと流路15が流路37で接続されており、一方、電極10と隔膜36で形成される隔室Bと流路15は流路38で接続されている。さらに、電解槽11の下流側には、流路15Aと流路切換弁39が備えられてり、隔室Aと流路切換弁39が流路40で、また、隔室Bと流路切換弁39が流路41で接続されている。また、流路切換弁39には流路42が接続されており、殺菌装置8外部に不要になった電解水を廃棄可能としている。
【0026】
なお、実施例1と同一符号のものは同一構造を有し、説明は省略する。
【0027】
次に動作、作用を説明すると、制御手段23で弁16を開くことで、水道水は、流路15、流路37、38を通って電解槽11内の隔室Aと隔室Bに入る。その後食塩ポンプ14を始動することで、隔室A、B内の塩素イオン濃度が一定レベルに保たれる。この状態で電極9、10に通電を行うことで、隔室Aには次亜塩素酸化合物を含み、pHが3以下の電解水が生成され、隔室Bには水酸化ナトリウムを含み、pHが11以上のアルカリ水が生成される。
【0028】
次に、排水部32の殺菌、脱臭を行う場合には、流路切換弁39を切換え、隔室A内の電解水が、流路15Aを通って流路末端15Bから排水部32に供給されるようにする。すなわち、電極9を陽極にして塩素イオンを含む水を電気分解することで、隔室Aの水には次亜塩素酸化合物と塩酸を含む電解水を生成することができ、pHが3.0以下になる。実施例1と同様にして弁16を開き、電解槽11内の隔室Aの電解水を水道水を介して排出し、排水部32の殺菌、脱臭を行うと、排水部32の表面に油脂類が付着した場合でも、ケン化反応が起こらないので白色異物(固形物)は生成されない。
【0029】
しかし、油脂が多量にあり、排水部32の表面に油脂類が固形化する場合がある。このような場合を想定して、電解水を排水部32に供給した後、例えば実施例1の場合では制御手段23により弁16を開き、洗剤ポンプ19によって洗剤タンク17から中性洗剤を送り込み、流路末端15Bから排出し、排水部32に接触するようにすることで、この表面に付着した油脂類を除去することができる。よって、外観を損なうことがないので、使用者が排水部32のお手入れを快適に行うことができる。
【0030】
(実施例
図4は本発明の実施例の殺菌装置を示す。本実施例において、実施例1と異なる点は流路15の上流側に温水供給手段として温水を供給可能な給湯器43を有している点にある。
【0031】
なお、実施例1と同一符号のものは同一構造を有し、説明は省略する。
【0032】
次に動作、作用を説明すると、電解槽11から電解水を排水部32に供給し殺菌、脱臭を行った後、弁16を開き給湯器43から所定温度の温水を排水部32に供給する。排水部32の表面には油脂類が付着しているが、温水の界面活性作用により油脂類が剥離除去されるので、ケン化物や固形化物が発生することが無い。従って、外観を損なうことがないので、使用者が排水部32のお手入れを快適に行うことができる。さらに、温水なので、有機物の排水中への混入がないので、環境負荷とはならない。
【0033】
なお、本実施例において温水の水温は40℃〜70℃の温度範囲の温水を供給することで油脂の除去効果を得ることができた。温水の温度は高い方が除去効果が高く、50℃以上でケン化物、油脂の固形化の発生は少なかった。
【0034】
なお、実施例1からにおいて、殺菌手段及び異物除去手段から供給される物質を流し台のシンク部、天板部、調理器具保管部に供給できるように搬送手段を配置してもよい。
【0035】
また、実施例1からにおいて、排水部32の上側から電解水を供給する構成としたが、対象となる場所に電解水ならびに油脂除去性物質を供給できればよいので、バスケット30の殺菌、脱臭を局所的に行いたい場合には、トラップ29に流路末端20ないし15Bを接続してもよいし、殺菌むらをなくすために流路15を分岐し、流路末端20ないし15Bを複数設け、トラップ29に接続してもよい。
【0036】
【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、微生物の増殖を抑制すると同時に、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。また、異物除去手段から供給される物質を界面活性剤としているので、固体表面に付着した油脂類が除去され、電気分解により生成した次亜塩素酸化合物または水酸化ナトリウムと油脂が固体表面で反応することが無くなり、固体表面を清浄な状態に保つことができる。

[0010]
FIG. 1 is a configuration diagram of a sterilization apparatus according to a first embodiment of the present invention, and FIG. 2 is a schematic view when the sterilization apparatus is used for sterilization of a kitchen sink.
[0011]
1 and 2, reference numeral 8 denotes a sterilizer, which includes an electrolytic cell 11 as an electrolysis unit provided with electrodes 9 and 10 and a chlorine supply unit for supplying chlorine ions to the electrolytic cell 11, in this embodiment A salt tank 12 storing salt water, a salt flow path 13 connecting the salt tank 12 and the electrolytic cell 11, and a salt pump 14 for feeding the salt solution to the electrolytic cell 11 through the salt flow path 13. Moreover, it has the valve | bulb 16 which controls the flow path 15 of the tap water connected to the water supply pipe indirectly or directly as a conveyance means, and the inflow / outflow of tap water. The foreign matter removing means includes a detergent tank 17 in which neutral detergent for kitchen is stored as a surfactant, and a detergent channel 18 connecting the detergent tank 17 and the channel 15.

The electrolyzed water generated in the electrolytic cell 11 is discharged from the end portion 20 of the flow path 15. The electrolytic cell 11 and the flow channel 15 are connected via the flow channels 21 and 22. By opening the valve 16, tap water passes from the flow channel 15 through the flow channel 21 and enters the electrolytic cell 11. A water circuit entering the flow path 15 again through the path 22 is formed.
[0012]
Furthermore, the energization of the electrodes 9 and 10 in the electrolytic cell 11 and the operation control of the valve 16, the salt pump 14 and the detergent pump 19 are performed by a control device 23 as a control means.
[0013]
FIG. 2 is a view showing an arrangement example in which the sterilizer 8 is installed on the sink 24. The sink 24 includes a sink portion 25, a work top portion 26, and a currant 27. 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.
[0014]
Next, the operation and action will be described. First, before sterilizing, deodorizing, and removing foreign matter from the drainage section 32 (the sink outlet 28, the basket 30, the trap 29, the drainage channel 31), the valve 16 is opened by the control device 23, and tap water is supplied into the sterilization device 8. Then, 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 is started, and the salt water in the salt tank 12 is passed through the salt flow path 13 by the salt pump 14 so that the chlorine ion concentration in the electrolytic cell 11 is a predetermined concentration. Send in to become. 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.

Therefore, it is possible to sterilize microorganisms such as bacteria and mold that propagate on these. Therefore, generation | occurrence | production of odor and reproduction | regeneration of a slime (biofilm) by propagation of microorganisms can be suppressed.
[0017]
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 saponification is easily generated. White foreign matters are generated all over the portion 32. Moreover, without reacting with the electrolytic water, the trap 29 together when the amount of oil is large time, the basket 30, gradually solidified occurs in discharge water channel 31 or the like, and at the same time disfiguring, these portions Many people feel uncomfortable to touch and feel uncomfortable. If this phenomenon further proceeds, the drainage channel 31 may be clogged.
[0018]
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.
[0019]
In the present embodiment, as the conveying means, the tap water flow path 15 indirectly or directly connected to the water pipe and the valve 16 for controlling the flow of tap water are used. The electrolytic water and the detergent remaining in the flow path 15 after the electrolytic water generated in the flow path 11 is sent to the flow path 15 or after the detergent is sent by the detergent pump 19 are washed away with tap water and do not remain in the flow path 15. The deterioration of the flow path 15 due to the electrolytic water and the detergent can be minimized, and at the same time, the electrolytic water and the detergent are long on the object to be treated (the drain port 28, the trap 29, the basket 30, and the drain path 31 in this embodiment). There is no time remaining, and deterioration of these materials can be minimized.
[0020]
In the present embodiment, the electrodes 9 and 10 of the electrolytic cell 11 are energized, and electrolyzed water is generated by electrolysis. Since electrolyzed water containing a constant concentration of hypochlorous acid compound can always be generated, There is no decrease in concentration due to standing for a long time like a drug, the concentration of the hypochlorous acid compound can be kept constant, and the sterilization and deodorizing performance can be stabilized. However, when the chlorine ion concentration in the raw water to be supplied is low, the concentration of the hypochlorous acid compound that can be generated by electrolysis is low, and sufficient sterilization and deodorizing ability cannot be obtained. A salt tank 12, a salt flow path 13, and a salt pump 14 are provided, and the chlorine ion concentration in the electrolytic cell 11 is set to a certain level or more. Therefore, if the amount of current flowing between the electrodes 9 and 10 is constant, electrolysis can be performed. The generated electrolyzed water concentration can be maintained at a constant concentration, and stable sterilization and deodorizing ability can be obtained.
[0021]
(Example 2)
FIG. 3 shows the second embodiment. The difference from the first embodiment is that a decomposing agent tank 33 for storing an enzyme lipase as an oil decomposing agent for decomposing fats and oils instead of the detergent tank 17, the detergent flow path 18 and the detergent pump 19. , Having a decomposing agent pump 34 and a decomposing agent flow path 35, by decomposing oil and fat by the action of an enzyme, removing oil and fat adhering to the drainage part 32, preventing generation of saponified products and solidification of oil and fat Is where you are.
[0022]
In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
[0023]
Next, the operation and action will be described. After the sterilization of the drainage part 32 with electrolyzed water, the decomposing agent pump 34 is started by the control means 23, and the lipase in the decomposing agent tank 33 is sent from the decomposing agent channel 35 to the channel 15. The oil and fat discharged from the flow path end 20 and adhering to the drainage part 32 is removed to prevent generation of saponified products and solidification of the oil and fat. By using an enzyme as a decomposing agent, it is possible to reliably remove oils and fats at the same time as reducing the environmental load compared to the case of using a surfactant. Furthermore, since the enzyme is used, the oil and fat decomposition reaction occurs continuously, so that the oil and fat can be effectively removed.
[0024]
In this example, lipase was used as a decomposing agent, but in addition to an enzyme such as lipase, for example, a weak alkali such as sodium percarbonate or a strong alkali such as sodium hydroxide was used to completely eliminate fat and oil. Can be removed.
[0025]
(Example 3)
Example 3 will be described with reference to FIG. The difference from the first embodiment is that a diaphragm 36 is provided between the electrodes 9 and 10, and a flow path switching valve 39 and flow paths 40, 41 and 42 are provided on the downstream side of the electrolytic cell 11. And it is in the point which produces | generates acidic electrolyzed water with the electrolytic vessel 11, and performs the disinfection and deodorization of the waste_water | drain part 32 using this. That is, the diaphragm 36 having material permeability is disposed between the electrodes 9 and 10. Further, on the upstream side of the electrolytic cell 11, the compartment A formed by the electrode 9 and the diaphragm 36 and the flow path 15 are connected by the flow path 37, while the compartment formed by the electrode 10 and the diaphragm 36. B and the flow path 15 are connected by a flow path 38. Further, on the downstream side of the electrolytic cell 11, a flow path 15A and a flow path switching valve 39 are provided, the compartment A and the flow path switching valve 39 are the flow path 40, and the compartment B and the flow path switching valve. A valve 39 is connected by a flow path 41. In addition, a flow path 42 is connected to the flow path switching valve 39 so that electrolyzed water that is no longer needed outside the sterilizer 8 can be discarded.
[0026]
In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
[0027]
Next, the operation and action will be described. By opening the valve 16 by the control means 23, the tap water enters the compartment A and the compartment B in the electrolytic cell 11 through the flow path 15 and the flow paths 37 and 38. . Thereafter, by starting the salt pump 14, the chlorine ion concentration in the compartments A and B is maintained at a constant level. By energizing the electrodes 9 and 10 in this state, the compartment A contains hypochlorous acid compound and electrolyzed water having a pH of 3 or less is generated, the compartment B contains sodium hydroxide, pH 11 or more alkaline water is produced.
[0028]
Next, when sterilizing and deodorizing the drainage section 32, the flow path switching valve 39 is switched, and the electrolyzed water in the compartment A is supplied to the drainage section 32 from the flow path end 15B through the flow path 15A. So that That is, by electrolyzing water containing chlorine ions using the electrode 9 as an anode, electrolyzed water containing a hypochlorous acid compound and hydrochloric acid can be generated in the water of the compartment A, and the pH is 3.0. It becomes the following. When the valve 16 is opened in the same manner as in Example 1 and the electrolyzed water in the compartment A in the electrolytic cell 11 is discharged via tap water and the drainage part 32 is sterilized and deodorized, oil and fat are deposited on the surface of the drainage part 32. Even if a kind adheres, no saponification reaction takes place, and no white foreign matter (solid matter) is produced.
[0029]
However, there is a large amount of oil and fat, and the oil and fat may solidify on the surface of the drainage part 32. Assuming such a case, after supplying the electrolyzed water to the drainage section 32, for example, in the case of Example 1, the valve 16 is opened by the control means 23, and the neutral detergent is sent from the detergent tank 17 by the detergent pump 19, By discharging from the channel end 15B and making contact with the drainage part 32, the oils and fats adhering to the surface can be removed. Therefore, since the appearance is not impaired, the user can comfortably clean the drainage section 32.
[0030]
(Example 4 )
Figure 4 shows the sterilizing apparatus according to a fourth embodiment of the present invention. The fourth embodiment is different from the first embodiment in that a hot water heater 43 capable of supplying hot water is provided on the upstream side of the flow path 15 as hot water supply means.
[0031]
In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
[0032]
Next, the operation and action will be described. After supplying electrolyzed water from the electrolytic cell 11 to the drainage part 32 to perform sterilization and deodorization, the valve 16 is opened and hot water of a predetermined temperature is supplied from the water heater 43 to the drainage part 32. Oils and fats adhere to the surface of the drainage part 32, but the oils and fats are peeled and removed by the surface-active action of warm water, so that saponified products and solidified products are not generated. Therefore, since the appearance is not impaired, the user can comfortably clean the drainage portion 32. Furthermore, since it is warm water, there is no contamination of organic matter in the wastewater, so there is no environmental impact.
[0033]
In addition, in the present Example, the water temperature of warm water was able to acquire the removal effect of fats and oils by supplying warm water of the temperature range of 40 to 70 degreeC. The higher the temperature of the hot water, the higher the removal effect, and the occurrence of solidification of saponified products and oils and fats was less at 50 ° C. or higher.
[0034]
In Examples 1 to 4 , the conveying means may be arranged so that the substances supplied from the sterilizing means and the foreign substance removing means can be supplied to the sink part, the top plate part, and the cooking utensil storage part of the sink.
[0035]
Moreover, in Example 1-4 , it was set as the structure which supplies electrolyzed water from the upper side of the waste_water | drain part 32, However, Since electrolyzed water and an oil-fat removal substance should just be able to be supplied to the object place, the disinfection and deodorizing of the basket 30 are carried out. If it is desired to carry out locally, the flow path ends 20 to 15B may be connected to the trap 29, or the flow path 15 is branched to eliminate sterilization unevenness, and a plurality of flow path ends 20 to 15B are provided. 29 may be connected.
[0036]
【The invention's effect】
As described above, according to the sterilization apparatus according to claim 1 of the present invention, the growth of microorganisms is suppressed, and at the same time, solidified fats and oils and saponification products adhere to the solid surface, and an oily odor is produced and the appearance is impaired. There is an effect that the clogging of the drainage port can be eliminated . In addition, since the substance supplied from the foreign matter removing means is used as a surfactant, the oils and fats adhering to the solid surface are removed, and the hypochlorite compound or sodium hydroxide generated by electrolysis reacts with the oil on the solid surface. And the solid surface can be kept clean.
