Description

本発明は、被洗浄物に液体を噴射して洗浄する洗浄器に関するものである。 The present invention relates to a cleaning device that performs cleaning by jetting a liquid onto an object to be cleaned.

従来、下記特許文献１に開示されるように、チャンバ（３）内にスプレー・アーム（８）を回転自在に設け、そのスプレー・アーム（８）のノズルから被洗浄物に液体を噴射して、被洗浄物の洗浄や消毒を図る洗浄器が知られている。この装置では、スプレー・アーム（８）から噴射された液体は、チャンバ（３）下部の収集スペース（１０）に集められ、循環ポンプ（１２）により循環パイプ（１６）を介してスプレー・アーム（８）へ循環供給される。 Conventionally, as disclosed in Patent Document 1 below, a spray arm (8) is rotatably provided in a chamber (3), and a liquid is ejected from a nozzle of the spray arm (8) onto an object to be cleaned. A cleaning device for cleaning or disinfecting an object to be cleaned is known. In this apparatus, the liquid ejected from the spray arm (8) is collected in a collection space (10) below the chamber (3), and is sprayed by the circulation pump (12) via the circulation pipe (16) ( It is circulated and supplied to 8).

この種の洗浄器では、洗浄力の向上や仕上げ状態の向上のために、ノズルへの循環水に薬品を投入する場合が多い。その場合、洗浄槽（チャンバ）下部に、水を貯留すると共に薬液を投入して洗浄水とする。そして、循環ポンプを作動させて、洗浄水を被洗浄物に噴射して洗浄後、洗浄槽内から洗浄水を排水し、所望によりこのような一連の洗浄工程を複数回行った後、濯ぎ工程として、新たに給水した水を濯ぎ水として被洗浄物を濯ぎして排水するが、この濯ぎ工程も設定回数だけ行われる。 In this type of washer, chemicals are often added to the circulating water to the nozzle in order to improve detergency and finish conditions. In that case, water is stored in the lower part of the cleaning tank (chamber) and a chemical solution is added to obtain cleaning water. Then, the circulation pump is operated, the cleaning water is sprayed onto the object to be cleaned, the cleaning water is drained from the cleaning tank, and if necessary, a series of cleaning processes are performed a plurality of times, followed by a rinsing process. In this case, the object to be cleaned is rinsed and drained using newly supplied water as rinsing water, and this rinsing process is performed a set number of times.

しかしながら、配管内に薬品が残ると、次のような不都合を生じる。すなわち、まず、異なる薬品同士の反応による生成物の析出が生じ、それが被洗浄物への異物混入を生じさせるおそれがある。また、濯ぎ水に薬品が混入することで、濯ぎ不足が生じるおそれがある。 However, if chemicals remain in the piping, the following inconvenience occurs. That is, first, a product is precipitated due to a reaction between different chemicals, which may cause contamination of the object to be cleaned. Moreover, there is a possibility that insufficient rinsing may occur due to chemicals mixed in the rinsing water.

本発明が解決しようとする課題は、薬液投入配管内に薬液が残留するのを防止して、被洗浄物への異物混入や濯ぎ不良を防止することにある。 The problem to be solved by the present invention is to prevent the chemical solution from remaining in the chemical solution supply pipe, and to prevent foreign matters from entering the object to be cleaned and poor rinsing.

本発明は、前記課題を解決するためになされたもので、請求項１に記載の発明は、被洗浄物が収容される洗浄槽と、この洗浄槽内の被洗浄物へ液体を噴射する洗浄ノズルと、前記洗浄槽内の下部に連接された液貯留部と、この液貯留部への給水手段と、前記液貯留部からの排水手段と、前記給水手段により給水された水への薬液供給手段と、前記液貯留部の液体を前記洗浄ノズルへ循環供給する循環手段とを備え、前記循環手段は、前記液貯留部から前記洗浄ノズルへの配管に、循環ポンプを備え、前記液貯留部から前記循環ポンプへの配管に、前記薬液供給手段による薬液の給液路が接続されたことを特徴とする洗浄器である。 The present invention has been made to solve the above problems, and the invention according to claim 1 is a cleaning tank in which an object to be cleaned is accommodated, and a cleaning in which liquid is jetted onto the object to be cleaned in the cleaning tank. Chemical supply to the water supplied by the nozzle, the liquid storage part connected to the lower part in the cleaning tank, the water supply means to the liquid storage part, the drainage means from the liquid storage part, and the water supply means And a circulation means for circulating and supplying the liquid in the liquid reservoir to the cleaning nozzle, and the circulation means includes a circulation pump in a pipe from the liquid reservoir to the cleaning nozzle, and the liquid reservoir To the circulation pump is connected to a chemical liquid supply path by the chemical liquid supply means.

請求項１に記載の発明によれば、水の循環配管、特に液貯留部から循環ポンプへの配管に、薬液の給液路を接続することで、循環ポンプの作動により、給液路内が循環ポンプに吸引される。そのため、給液路内に薬液が残留していても、水の循環に伴い、給液路内の残液が循環水に引き込まれ、薬液の残留を防止することができる。これにより、被洗浄物への異物混入や濯ぎ不良を防止することができる。 According to the first aspect of the present invention, by connecting the chemical liquid supply path to the water circulation pipe, in particular, the pipe from the liquid storage portion to the circulation pump, the inside of the liquid supply path is caused by the operation of the circulation pump. It is sucked into the circulation pump. Therefore, even if the chemical liquid remains in the liquid supply path, the residual liquid in the liquid supply path is drawn into the circulating water as the water circulates, thereby preventing the chemical liquid from remaining. Thereby, it is possible to prevent foreign matters from being mixed into the object to be cleaned and poor rinsing.

請求項２に記載の発明は、前記給液路には、薬液の供給の有無を切り替える薬液ポンプが設けられ、この薬液ポンプより下流部と前記液貯留部とが通水路で接続されたことを特徴とする請求項１に記載の洗浄器である。 According to a second aspect of the present invention, the liquid supply path is provided with a chemical pump that switches the presence / absence of supply of the chemical liquid, and a downstream portion of the chemical liquid pump and the liquid storage section are connected by a water passage.

A water channel from the reservoir is connected. Therefore, when the circulation pump is operated, the stored water in the liquid storage section is not only sucked into the circulation pump via the circulation pipe, but also via the water passage and the liquid supply path (the liquid supply path downstream from the chemical liquid pump). It is sucked into the circulation pump. In this way, since the inside of the liquid supply path is purged every time the circulation pump moves, it is possible to more reliably prevent the chemical liquid from remaining in the liquid supply path.

さらに、請求項３に記載の発明は、前記薬液供給手段は、異なる薬液を貯留した複数の薬液タンクと、各薬液タンクからの前記給液路と、各給液路に設けられた薬液ポンプとを備え、前記給水手段により前記液貯留部に給水した後、前記循環ポンプを作動させた状態で、前記複数の薬液ポンプの内、いずれかの薬液ポンプを設定時間だけ作動させて、循環水に薬液を混入することを特徴とする請求項１または請求項２に記載の洗浄器である。 Furthermore, the invention according to claim 3 is characterized in that the chemical liquid supply means includes a plurality of chemical liquid tanks storing different chemical liquids, the liquid supply path from each chemical liquid tank, and a chemical liquid pump provided in each liquid supply path. And after supplying water to the liquid reservoir by the water supply means, in a state where the circulation pump is operated, any one of the plurality of chemical liquid pumps is operated for a set time so that the circulating water is obtained. The cleaning device according to claim 1 or 2, wherein a chemical solution is mixed.

請求項３に記載の発明によれば、循環水に混入する薬液の種類を、被洗浄物や工程などに応じて、適宜変更することができる。そして、たとえば工程に応じて薬液の種類を変更しても、給液路内の薬液の残留が防止されるので、異なる薬液同士が混ざることが防止される。従って、異なる薬液同士の反応による生成物の析出が防止され、被洗浄物への異物混入のおそれがない。 According to invention of Claim 3, the kind of chemical | medical solution mixed in circulating water can be changed suitably according to a to-be-washed object, a process, etc. And even if it changes the kind of chemical | medical solution according to a process, for example, since the chemical | medical solution remains in a liquid supply path, it is prevented that different chemical | medical solutions mix. Therefore, the precipitation of the product due to the reaction between different chemical solutions is prevented, and there is no fear of foreign matter mixing into the object to be cleaned.

本発明の洗浄器によれば、薬液投入配管内に薬液が残留するのを防止して、被洗浄物への異物混入や濯ぎ不良を防止することができる。 According to the cleaning device of the present invention, it is possible to prevent the chemical solution from remaining in the chemical solution supply pipe, and to prevent foreign matters from being mixed into the object to be cleaned and poor rinsing.

In the cleaning tank 2, cleaning nozzles 3 are provided in a plurality of upper and lower stages, and an object to be cleaned is disposed between the upper and lower cleaning nozzles 3. At this time, an object to be cleaned is placed on a net shelf (not shown) provided in the upper and lower stages in the cleaning tank 2. The object to be cleaned may be accommodated in a basket or the like as desired.

洗浄槽２は、被洗浄物が収容される中空容器である。洗浄槽２は、本実施例では略矩形の中空ボックス状である。洗浄槽２は、ドア（図示省略）により開閉可能とされる。ドアを開けることで、洗浄槽２に対し被洗浄物を出し入れすることができる。ドアは、洗浄槽２の正面に設けられるが、洗浄槽２の正面および背面の双方に設けられてもよい。なお、図示例では、洗浄槽２の上壁と左右側壁とに、連続的な空洞部としてのジャケット１２が設けられており、このジャケット１２は、左右側壁の下端部において洗浄槽２内へ開口する。但し、このようなジャケット１２は、場合により設置を省略することもできる。 The cleaning tank 2 is a hollow container that accommodates an object to be cleaned. In the present embodiment, the cleaning tank 2 has a substantially rectangular hollow box shape. The cleaning tank 2 can be opened and closed by a door (not shown). The object to be cleaned can be taken in and out of the cleaning tank 2 by opening the door. The door is provided on the front surface of the cleaning tank 2, but may be provided on both the front surface and the back surface of the cleaning tank 2. In the illustrated example, a jacket 12 as a continuous cavity is provided on the upper wall and the left and right side walls of the cleaning tank 2, and the jacket 12 opens into the cleaning tank 2 at the lower ends of the left and right side walls. To do. However, such a jacket 12 can be omitted in some cases.

洗浄ノズル３は、洗浄槽２内に、上下複数段に設けられる。本実施例では、洗浄槽２の一側部に、上下複数段にアーム状の支持部材１３の基端部が保持され、各支持部材１３は、洗浄槽２の一側部から左右方向中央部へ向けて延出する。そして、その延出先端部に、洗浄ノズル３の長手方向中央部が垂直軸まわりに回転自在に保持される。洗浄ノズル３は、支持部材１３内を介して供給される流体（液体や空気）を噴射させるノズル孔（図示省略）を複数形成されている。支持部材１３を介して洗浄ノズル３内に流体が供給されると、その流体は洗浄ノズル３のノズル孔から噴射される。この噴流により、洗浄ノズル３は、支持部材１３の端部の軸受部まわりに回転する。なお、洗浄槽２内の上端部に設けられる洗浄ノズル３は、下方へのみ流体を噴射し、洗浄槽２内の下端部に設けられる洗浄ノズル３は、上方へのみ流体を噴射し、上下両端部以外の洗浄ノズル３は、上下両方へ流体を噴射する。 The cleaning nozzle 3 is provided in the cleaning tank 2 in multiple upper and lower stages. In the present embodiment, the base end portion of the arm-shaped support member 13 is held in one side portion of the cleaning tank 2 in a plurality of upper and lower stages, and each support member 13 extends from one side portion of the cleaning tank 2 to the center in the left-right direction. Extend towards. Then, the central portion in the longitudinal direction of the cleaning nozzle 3 is held at the extended tip portion so as to be rotatable around the vertical axis. The cleaning nozzle 3 is formed with a plurality of nozzle holes (not shown) for ejecting fluid (liquid or air) supplied through the support member 13. When a fluid is supplied into the cleaning nozzle 3 through the support member 13, the fluid is ejected from the nozzle hole of the cleaning nozzle 3. With this jet, the cleaning nozzle 3 rotates around the bearing portion at the end of the support member 13. The cleaning nozzle 3 provided at the upper end in the cleaning tank 2 ejects fluid only downward, and the cleaning nozzle 3 provided at the lower end in the cleaning tank 2 ejects fluid upward only, The cleaning nozzles 3 other than the unit inject fluids both upward and downward.

液貯留部４は、洗浄槽２内の下部に連接される。言い換えれば、洗浄槽２は、下部に液貯留部４を備える。本実施例では、洗浄槽２の下壁は、左右両端部が左右方向内側へ行くに従って下方へ傾斜する傾斜面２ａに形成されており、左右方向中央部は下方へ略矩形状に凹んで形成されており、この凹部を含んだ形で、洗浄槽２内の下部が液貯留部４とされる。循環手段８の作動中、洗浄ノズル３から洗浄槽２内へ噴射された液体は、洗浄槽２内の下方へ落下し、傾斜面２ａにより凹部に集められる。 The liquid storage unit 4 is connected to the lower part in the cleaning tank 2. In other words, the cleaning tank 2 includes the liquid storage unit 4 in the lower part. In the present embodiment, the lower wall of the cleaning tank 2 is formed as an inclined surface 2a that is inclined downward as both left and right end portions go inward in the left-right direction, and the central portion in the left-right direction is recessed downward in a substantially rectangular shape. The lower part in the cleaning tank 2 is the liquid storage part 4 in a form including the concave part. During the operation of the circulation means 8, the liquid sprayed from the cleaning nozzle 3 into the cleaning tank 2 falls downward in the cleaning tank 2, and is collected in the recess by the inclined surface 2a.

給水手段５は、洗浄槽２下部の液貯留部４に、給水路１４を介して給水する。本実施例では、給水路１４からの給水は、洗浄槽２の上部からジャケット１２を介して液貯留部４に送られる。給水路１４には、洗浄槽２へ向けて、逆止弁１５と給水弁１６とが設けられる。なお、図示例では、給水路１４を一本のみ示しているが、所望により複数の給水路１４を並列に設けて、複数種の水から選択した水を供給可能としてもよい。たとえば、水道水の他、温水およびＲＯ水（逆浸透膜濾過水）の各給水路１４を設けて、被洗浄物や工程などに応じて所望の水を供給可能としてもよい。 The water supply means 5 supplies water to the liquid storage section 4 at the lower part of the cleaning tank 2 via a water supply path 14. In the present embodiment, the water supply from the water supply channel 14 is sent from the upper part of the cleaning tank 2 to the liquid storage unit 4 via the jacket 12. A check valve 15 and a water supply valve 16 are provided in the water supply path 14 toward the cleaning tank 2. In the illustrated example, only one water supply channel 14 is shown, but a plurality of water supply channels 14 may be provided in parallel as desired to supply water selected from a plurality of types of water. For example, in addition to tap water, each water supply channel 14 of warm water and RO water (reverse osmosis membrane filtered water) may be provided so that desired water can be supplied according to the object to be cleaned, the process, and the like.

液貯留部４付きの洗浄槽２には、液位検出器（図示省略）が設けられる。液位検出器は、その構成を特に問わないが、たとえば、液貯留部４の底部に設置した圧力センサから構成される。この場合、液貯留部４（および洗浄槽２）内の液位に応じて、水圧が変わることを利用して液位を把握する。なお、洗浄槽２には、所定以上の液体を外部へ排出するオーバーフロー路１７が設けられる。 The cleaning tank 2 with the liquid storage part 4 is provided with a liquid level detector (not shown). Although the liquid level detector does not ask | require the structure in particular, For example, it is comprised from the pressure sensor installed in the bottom part of the liquid storage part 4. FIG. In this case, the liquid level is grasped by utilizing the fact that the water pressure changes according to the liquid level in the liquid storage unit 4 (and the cleaning tank 2). The cleaning tank 2 is provided with an overflow path 17 for discharging a predetermined amount or more of liquid to the outside.

排水手段６は、洗浄槽２下部の液貯留部４から、排水路１８を介して排水する。排水路１８には、排水弁１９が設けられる。排水弁１９を開くことで、液貯留部４内の貯留水を外部へ排水することができる。 The drainage means 6 drains from the liquid storage part 4 at the lower part of the cleaning tank 2 via a drainage channel 18. A drain valve 19 is provided in the drain channel 18. By opening the drain valve 19, the stored water in the liquid storage unit 4 can be drained to the outside.

薬液供給手段７は、給水手段５により給水された水（言い換えれば循環手段８による循環水）に、給液路２０を介して薬液を混入する。具体的には、薬液が貯留された薬液タンク２１が、給液路２０を介して、後述する循環配管２３と接続されている。そして、給液路２０には、薬液ポンプ２２が設けられている。薬液ポンプ２２の作動を制御することで、薬液の投入量を調整することができる。給液路２０や循環配管２３などの配管構成の詳細については、後述する。 The chemical solution supply unit 7 mixes the chemical solution into the water supplied by the water supply unit 5 (in other words, the circulating water from the circulation unit 8) via the liquid supply path 20. Specifically, a chemical tank 21 in which a chemical is stored is connected to a circulation pipe 23 described later via a liquid supply path 20. The liquid supply path 20 is provided with a chemical pump 22. By controlling the operation of the chemical liquid pump 22, the amount of the chemical liquid input can be adjusted. Details of the pipe configuration such as the liquid supply path 20 and the circulation pipe 23 will be described later.

循環手段８は、液貯留部４内の貯留液を、洗浄ノズル３へ循環供給する。具体的には、循環手段８は、循環配管２３と循環ポンプ２４とを備える。循環配管２３は、液貯留部４から各洗浄ノズル３の支持部材１３への配管であり、その途中に循環ポンプ２４が設けられる。以下、説明の便宜上、循環配管２３の内、循環ポンプ２４より上流側（つまり液貯留部４から循環ポンプ２４の吸込口への配管）を上流側循環配管２３ａといい、循環ポンプ２４より下流側（つまり循環ポンプ２４の吐出口から洗浄ノズル３の支持部材１３への配管）を下流側循環配管２３ｂということにする。 The circulation means 8 circulates and supplies the stored liquid in the liquid storage unit 4 to the cleaning nozzle 3. Specifically, the circulation means 8 includes a circulation pipe 23 and a circulation pump 24. The circulation pipe 23 is a pipe from the liquid storage unit 4 to the support member 13 of each cleaning nozzle 3, and a circulation pump 24 is provided in the middle thereof. Hereinafter, for convenience of explanation, the upstream side of the circulation pump 24 in the circulation pipe 23 (that is, the pipe from the liquid storage unit 4 to the suction port of the circulation pump 24) is referred to as the upstream circulation pipe 23a and is downstream of the circulation pump 24. In other words, the pipe from the discharge port of the circulation pump 24 to the support member 13 of the cleaning nozzle 3 is referred to as a downstream circulation pipe 23b.

図示例では、上流側循環配管２３ａは、上流側（つまり液貯留部４側）において、排水路１８と共通管路とされている。循環ポンプ２４を作動させると、液貯留部４内の液体を、循環配管２３および支持部材１３を介して洗浄ノズル３へ供給することができ、洗浄ノズル３から噴射された液体は、液貯留部４に戻される。 In the illustrated example, the upstream circulation pipe 23a is a common pipe line with the drainage path 18 on the upstream side (that is, the liquid storage unit 4 side). When the circulation pump 24 is operated, the liquid in the liquid reservoir 4 can be supplied to the cleaning nozzle 3 via the circulation pipe 23 and the support member 13, and the liquid ejected from the cleaning nozzle 3 Returned to 4.

上流側循環配管２３ａには、薬液の給液路２０が接続される。そのため、循環ポンプ２４の作動中、薬液ポンプ２２を作動させると、循環水（ひいては液貯留部４の貯留水）に薬液を投入することができる。上流側循環配管２３ａに薬液の給液路２０を接続したので、循環ポンプ２４の作動中、給液路２０内が循環ポンプ２４に吸引される。これにより、薬液の投入が円滑になされると共に、薬液ポンプ２２の停止後、薬液ポンプ２２より下流の給液路２０内に薬液が残留するのが防止され、被洗浄物への異物混入や濯ぎ不良を防止することができる。なお、上流側循環配管２３ａへの給液路２０の接続箇所は、液貯留部４から循環ポンプ２４への配管であれば特に問わず、排水路１８との分岐部よりも上流側（つまり上流側循環配管２３ａと排水路１８との共通管路）でもよいし、排水路１８との分岐部よりも下流側でもよい。 A chemical liquid supply path 20 is connected to the upstream circulation pipe 23a. Therefore, when the chemical pump 22 is operated during the operation of the circulation pump 24, the chemical liquid can be poured into the circulating water (and eventually the stored water in the liquid storage unit 4). Since the chemical liquid supply path 20 is connected to the upstream circulation pipe 23 a, the inside of the liquid supply path 20 is sucked into the circulation pump 24 during the operation of the circulation pump 24. Thus, the chemical liquid can be smoothly charged, and after the chemical liquid pump 22 is stopped, the chemical liquid is prevented from remaining in the liquid supply path 20 downstream from the chemical liquid pump 22, so that foreign matter is mixed into the object to be cleaned or rinsed. Defects can be prevented. In addition, the connection location of the liquid supply path 20 to the upstream circulation pipe 23a is not particularly limited as long as it is a pipe from the liquid storage section 4 to the circulation pump 24. A common pipe line of the side circulation pipe 23 a and the drainage channel 18) or a downstream side of a branching portion with the drainage channel 18.

本実施例ではさらに、薬液の給液路２０の内、薬液ポンプ２２より下流部と、液貯留部４とが、通水路２５で接続される。この際、通水路２５の一端部は、液貯留部４の下部に接続されるのが好ましい。また、通水路２５の他端部は、給液路２０への接続部が、給液路２０の内、薬液ポンプ２２の吐出口に近いほど好ましい。そのため、最も好ましくは、通水路２５の他端部は、給液路２０の内、薬液ポンプ２２の出口部（つまり薬液ポンプ２２の吐出口に隣接した箇所）に接続される。なお、給液路２０および通水路２５は、典型的には、循環配管２３よりも小径に形成される。 In the present embodiment, further, the downstream portion of the chemical liquid supply path 20 from the chemical liquid pump 22 and the liquid storage section 4 are connected by a water passage 25. At this time, one end portion of the water passage 25 is preferably connected to the lower portion of the liquid storage portion 4. Further, the other end of the water passage 25 is preferably such that the connection to the liquid supply path 20 is closer to the discharge port of the chemical liquid pump 22 in the liquid supply path 20. Therefore, most preferably, the other end portion of the water passage 25 is connected to an outlet portion of the chemical liquid pump 22 in the liquid supply passage 20 (that is, a location adjacent to the discharge port of the chemical liquid pump 22). The liquid supply path 20 and the water passage 25 are typically formed with a smaller diameter than the circulation pipe 23.

いずれにしても、通水路２５を設けることで、循環ポンプ２４の作動中、液貯留部４内の貯留水は、上流側循環配管２３ａを介して循環ポンプ２４に吸い込まれる以外に、通水路２５および給液路２０（薬液ポンプ２２より下流の給液路２０）を介しても循環ポンプ２４に吸い込まれる。従って、循環ポンプ２４の作動中に、薬液ポンプ２２を作動させれば、循環水への薬液の投入を円滑に行える。また、薬液ポンプ２２の停止後には、循環ポンプ２４が動く度に給液路２０内が循環水でパージされるため、給液路２０内の薬液の残留を一層確実に防止することができる。 In any case, by providing the water passage 25, during operation of the circulation pump 24, the stored water in the liquid storage unit 4 is not drawn into the circulation pump 24 through the upstream circulation pipe 23 a, but the water passage 25. Also, it is sucked into the circulation pump 24 through the liquid supply path 20 (the liquid supply path 20 downstream from the chemical liquid pump 22). Therefore, if the chemical pump 22 is operated during the operation of the circulation pump 24, the chemical liquid can be smoothly introduced into the circulating water. Further, after the chemical liquid pump 22 is stopped, every time the circulation pump 24 moves, the inside of the liquid supply path 20 is purged with the circulating water, so that the remaining of the chemical liquid in the liquid supply path 20 can be more reliably prevented.

なお、循環ポンプ２４の発停により給液路２０内の圧力変動が起こり得るため、薬液ポンプ２２として、止水性の高いポンプ（たとえばチューブポンプなど）を用いるのが好ましい。また、薬液ポンプ２２の作動による薬液の投入は、循環ポンプ２４の作動中に行うのが好ましいが、場合により、循環ポンプ２４の停止中（循環開始前）に行うこともできる。その場合でも、薬液投入後に循環ポンプ２４を作動させることで、薬液ポンプ２２よりも下流の給液路２０内の残液を循環水で洗い流して、薬液の残留を防止することができる。 In addition, since the pressure fluctuation in the liquid supply path 20 may occur due to the start / stop of the circulation pump 24, it is preferable to use a pump with high water stoppage (for example, a tube pump) as the chemical liquid pump 22. In addition, it is preferable that the chemical solution is supplied by operating the chemical pump 22 while the circulation pump 24 is operating. However, in some cases, the chemical solution can be supplied while the circulation pump 24 is stopped (before the circulation is started). Even in such a case, by operating the circulation pump 24 after charging the chemical liquid, the residual liquid in the liquid supply path 20 downstream from the chemical liquid pump 22 can be washed away with the circulating water to prevent the chemical liquid from remaining.

ところで、薬液タンク２１および給液路２０のセットを並列に複数設けておき、薬液の種類を変更可能としてもよい。たとえば、アルカリ性洗剤、酵素配合洗剤、潤滑防錆剤、乾燥促進剤など、所望の薬液を貯留した薬液タンク２１を複数備え、被洗浄物や工程に応じて、使用する薬液を変更してもよい。その場合も、各給液路２０は、それぞれ（あるいは各薬液ポンプ２２より下流において統一管路にまとめられて）、上流側循環配管２３ａに接続される。さらに、各給液路２０（あるいは前記統一配管）には、薬液ポンプ２２より下流部と液貯留部４とが通水路２５で接続されるのがよい。 By the way, a plurality of sets of the chemical liquid tank 21 and the liquid supply path 20 may be provided in parallel so that the type of the chemical liquid can be changed. For example, a plurality of chemical tanks 21 storing desired chemicals such as alkaline detergents, enzyme-containing detergents, lubricating rust preventives, and drying accelerators may be provided, and the chemicals to be used may be changed depending on the object to be cleaned and the process. . Also in this case, each liquid supply path 20 is connected to the upstream-side circulation pipe 23a (or combined into a unified pipe downstream from each chemical pump 22). Furthermore, it is preferable that a downstream portion from the chemical liquid pump 22 and the liquid storage section 4 are connected to each liquid supply path 20 (or the unified pipe) by a water passage 25.

第一ヒータ１０は、本実施例では液貯留部４に設けられて、貯留液を加熱する。但し、場合により、第一ヒータ１０は、前記循環配管２３に設けられて、循環液を加熱してもよい。第一ヒータ１０は、電気ヒータであってもよいが、図示例では蒸気ヒータである。蒸気ヒータは、蒸気管内に給蒸路２６を介して蒸気が供給可能とされ、蒸気の凝縮水は蒸気トラップ２７および逆止弁２８を介してドレン排出路２９から排出される。給蒸路２６に設けた給蒸弁３０の開閉または開度を制御することで、貯留液の温度を調整することができる。 The 1st heater 10 is provided in the liquid storage part 4 in a present Example, and heats a stored liquid. However, in some cases, the first heater 10 may be provided in the circulation pipe 23 to heat the circulating liquid. The first heater 10 may be an electric heater, but is a steam heater in the illustrated example. The steam heater can supply steam into the steam pipe via the steam supply path 26, and the condensed water of the steam is discharged from the drain discharge path 29 via the steam trap 27 and the check valve 28. The temperature of the stored liquid can be adjusted by controlling the opening / closing or opening of the steam supply valve 30 provided in the steam supply path 26.

送風機９は、洗浄槽２の上部に、給気路３１を介して接続される。送風機９からの給気路３１は、第二ヒータ１１の出口側で分岐され、第一給気路３１ａが給気弁３２を介して前記循環配管２３に接続され、第二給気路３１ｂが洗浄槽２上部のジャケット１２に接続される。送風機９は、フィルタ３３を介した空気を吸い込んで吐出し、第二ヒータ１１を介して洗浄槽２内へ送り込む。つまり、送風機９からの空気は、第二ヒータ１１で加熱された後、第一給気路３１ａ、循環配管２３および支持部材１３を介して、洗浄ノズル３から噴射される一方、第二給気路３１ｂおよびジャケット１２を介して、洗浄槽２内へ供給される。 The blower 9 is connected to the upper part of the cleaning tank 2 via an air supply path 31. The air supply path 31 from the blower 9 is branched on the outlet side of the second heater 11, the first air supply path 31 a is connected to the circulation pipe 23 via the air supply valve 32, and the second air supply path 31 b is connected. It is connected to the jacket 12 at the top of the cleaning tank 2. The blower 9 sucks and discharges air through the filter 33 and sends it into the cleaning tank 2 through the second heater 11. That is, the air from the blower 9 is heated by the second heater 11 and then injected from the cleaning nozzle 3 through the first air supply path 31 a, the circulation pipe 23 and the support member 13, while the second air supply It is supplied into the cleaning tank 2 through the passage 31b and the jacket 12.

洗浄槽２の上部には、外部への排気路３４が接続される。図示例では、排気路３４からの排気は、一部が外部へ排気されつつ、残部が戻し路３５を介して送風機９の吸込口へ戻される。この戻し量を所望に保つために、排気路３４には、戻し路３５との分岐部より下流にオリフィス３６が設けられる。この場合、送風機９には、洗浄槽２からの排気とフィルタ３３を介した新規空気とが供給され、空気を一部入れ替えながら、洗浄槽２との間で空気を循環させることができる。但し、洗浄槽２からの排気は、一部を入れ替えながら循環させる以外に、全量を外部へ排出してもよい。その場合、戻し路３５およびオリフィス３６の設置は省略され、その代わりに、排気路３４に、排気中の水分を凝縮するための凝縮器を設けてもよい。 An exhaust path 34 to the outside is connected to the upper part of the cleaning tank 2. In the illustrated example, a part of the exhaust from the exhaust path 34 is exhausted to the outside, and the remaining part is returned to the suction port of the blower 9 via the return path 35. In order to keep this return amount as desired, the exhaust passage 34 is provided with an orifice 36 downstream from the branch portion with the return passage 35. In this case, the blower 9 is supplied with exhaust air from the cleaning tank 2 and new air through the filter 33, and air can be circulated between the cleaning tank 2 while partially replacing the air. However, the exhaust from the cleaning tank 2 may be exhausted to the outside in addition to circulating while exchanging a part. In that case, installation of the return path 35 and the orifice 36 is omitted, and instead, a condenser for condensing moisture in the exhaust gas may be provided in the exhaust path 34.

洗浄器１は、さらに加熱タンク３７を備えてもよい。加熱タンク３７は、後の工程で用いる液体を予め加熱するのに用いられる。本実施例では、加熱タンク３７は、設置スペースの関係上、洗浄槽２の上部に設けられる。 The cleaning device 1 may further include a heating tank 37. The heating tank 37 is used for preheating a liquid used in a later process. In the present embodiment, the heating tank 37 is provided in the upper part of the cleaning tank 2 because of the installation space.

加熱タンク３７には、タンク給水路３８を介して水が供給される。タンク給水路３８にはタンク給水弁３９が設けられており、タンク給水弁３９の開閉により、加熱タンク３７への給水を制御することができる。本実施例では、加熱タンク３７には、水位検出器（図示省略）が設けられており、少なくとも満水状態（設定水位までの給水状態）と空水状態とが検知可能とされる。水位検出器の検出信号に基づきタンク給水弁３９を制御して、加熱タンク３７に設定水位まで給水することができる。なお、加熱タンク３７には、所定以上の水を溢れされるオーバーフロー路４０が設けられている。 Water is supplied to the heating tank 37 via a tank water supply path 38. A tank water supply valve 39 is provided in the tank water supply path 38, and water supply to the heating tank 37 can be controlled by opening and closing the tank water supply valve 39. In the present embodiment, the heating tank 37 is provided with a water level detector (not shown) so that at least a full water state (a water supply state up to a set water level) and an air water state can be detected. Based on the detection signal of the water level detector, the tank water supply valve 39 can be controlled to supply water to the heating tank 37 up to the set water level. The heating tank 37 is provided with an overflow path 40 that overflows water of a predetermined amount or more.

加熱タンク３７には、第三ヒータ４１が設けられる。第三ヒータ４１は、図示例では電気ヒータとされるが、場合により第一ヒータ１０と同様の蒸気ヒータであってもよい。第三ヒータ４１により、加熱タンク３７内の液体を設定温度まで加熱することができる。典型的には、後述する除染工程で使用する熱水を製造することができる。 A third heater 41 is provided in the heating tank 37. The third heater 41 is an electric heater in the illustrated example, but may be a steam heater similar to the first heater 10 in some cases. The liquid in the heating tank 37 can be heated to the set temperature by the third heater 41. Typically, hot water used in the decontamination process described below can be produced.

加熱タンク３７と洗浄槽２とは、熱水路４２により接続されており、熱水路４２には熱水弁４３が設けられている。図示例では、熱水路４２は、下流（洗浄槽２側）において、給水路１４と共通管路とされている。熱水弁４３を開くことで、加熱タンク３７から洗浄槽２内へ熱水を供給することができる。 The heating tank 37 and the washing tank 2 are connected by a hot water passage 42, and a hot water valve 43 is provided in the hot water passage 42. In the illustrated example, the hot water channel 42 is a common pipe line with the water supply channel 14 in the downstream (washing tank 2 side). By opening the hot water valve 43, hot water can be supplied from the heating tank 37 into the cleaning tank 2.

洗浄槽２には、さらに、超音波振動子４４を設けてもよい。本実施例では、洗浄槽２の下壁の左右の傾斜面２ａに、それぞれ超音波振動子４４が設けられている。 The cleaning tank 2 may further be provided with an ultrasonic transducer 44. In the present embodiment, ultrasonic transducers 44 are provided on the left and right inclined surfaces 2a of the lower wall of the cleaning tank 2, respectively.

液貯留部４には、第一温度センサ４５が設けられる。第一温度センサ４５の検出温度に基づき第一ヒータ１０を制御（本実施例では給蒸弁３０を制御）することで、液貯留部４内の貯留水、ひいては洗浄ノズル３から噴射する液体の温度を調整することができる。 The liquid storage unit 4 is provided with a first temperature sensor 45. By controlling the first heater 10 based on the temperature detected by the first temperature sensor 45 (in the present embodiment, the steam supply valve 30 is controlled), the water stored in the liquid storage unit 4 and the liquid ejected from the cleaning nozzle 3 are controlled. The temperature can be adjusted.

送風機９から洗浄槽２への給気路３１には、第二ヒータ１１の設置位置よりも下流側に、第二温度センサ４６が設けられる。第二温度センサ４６の検出温度に基づき第二ヒータ１１を制御することで、洗浄槽２内への給気温度を調整することができる。 A second temperature sensor 46 is provided in the air supply path 31 from the blower 9 to the cleaning tank 2 on the downstream side of the installation position of the second heater 11. By controlling the second heater 11 based on the temperature detected by the second temperature sensor 46, the supply air temperature into the cleaning tank 2 can be adjusted.

By controlling the third heater 41 based on the temperature detected by the third temperature sensor 47, the stored water in the heating tank 37 can be adjusted to a desired temperature.

洗浄器１は、さらに制御手段としての制御器（図示省略）を備える。具体的には、給水弁１６、排水弁１９、薬液ポンプ２２、循環ポンプ２４、送風機９、給気弁３２、タンク給水弁３９、熱水弁４３、第一ヒータ１０（給蒸弁３０）、第二ヒータ１１、第三ヒータ４１、超音波振動子４４、液貯留部４の液位検出器、加熱タンク３７の水位検出器、第一温度センサ４５、第二温度センサ４６および第三温度センサ４７などは、制御器に接続されている。そして、制御器は、以下に述べるように、所定の手順（プログラム）に従い、洗浄槽２内の被洗浄物の洗浄や濯ぎなどを図る。 The cleaning device 1 further includes a controller (not shown) as control means. Specifically, the water supply valve 16, the drain valve 19, the chemical pump 22, the circulation pump 24, the blower 9, the air supply valve 32, the tank water supply valve 39, the hot water valve 43, the first heater 10 (the steam supply valve 30), Second heater 11, third heater 41, ultrasonic transducer 44, liquid level detector of liquid reservoir 4, water level detector of heating tank 37, first temperature sensor 45, second temperature sensor 46, and third temperature sensor 47 etc. are connected to the controller. The controller then cleans or rinses the object to be cleaned in the cleaning tank 2 according to a predetermined procedure (program) as described below.

以下、本実施例の洗浄器１の運転について具体的に説明する。初期状態において、各弁１６，１９，３０，３２，３９，４３は閉じられ、各ポンプ２２，２４、各ヒータ１０，１１，４１、送風機９および超音波振動子４４は停止している。但し、排水弁１９は、運転開始前には開いた状態にしておき、運転開始時に閉じてもよい。いずれにしても、運転開始に先立って、洗浄槽２内には、被洗浄物が収容され、洗浄槽２のドアは気密に閉じられる。 Hereinafter, the operation of the cleaning device 1 of the present embodiment will be specifically described. In the initial state, the valves 16, 19, 30, 32, 39, 43 are closed, and the pumps 22, 24, the heaters 10, 11, 41, the blower 9, and the ultrasonic vibrator 44 are stopped. However, the drain valve 19 may be opened before the operation is started and closed when the operation is started. In any case, before the start of operation, an object to be cleaned is accommodated in the cleaning tank 2, and the door of the cleaning tank 2 is closed in an airtight manner.

本実施例の洗浄器１は、予洗工程、シャワー洗浄工程、超音波洗浄工程、濯ぎ工程、除染工程および乾燥工程の内、選択された工程を実行する。どの工程をどのような順序で行うか（また各工程を何回行うか）は、運転開始に先立ち、ユーザにより制御器に設定される。たとえば、シャワー洗浄工程（および／または超音波洗浄工程）と濯ぎ工程とを順次に含んで実行する。典型的には、予洗工程を所望により行った後、シャワー洗浄工程と濯ぎ工程を順次に行い、その後、必要に応じて除染工程を行った後、最後に、乾燥工程を実行する。いずれにしても、所定の運転開始ボタンにより運転開始が指示されると、制御器は、選択された工程を順次に実行する。以下、各工程の具体的内容を説明する。なお、以下において、設定温度は、工程ごとに異なったものとでき、設定時間も、工程ごとに異なったものとできるのは、言うまでもない。 The cleaning device 1 of the present embodiment executes a selected process among a pre-cleaning process, a shower cleaning process, an ultrasonic cleaning process, a rinsing process, a decontamination process, and a drying process. Which process is performed in what order (and how many times each process is performed) is set in the controller by the user prior to the start of operation. For example, a shower cleaning process (and / or an ultrasonic cleaning process) and a rinsing process are sequentially included and executed. Typically, after a pre-washing process is performed as desired, a shower cleaning process and a rinsing process are sequentially performed, and then a decontamination process is performed as necessary, and finally a drying process is performed. In any case, when the operation start is instructed by a predetermined operation start button, the controller sequentially executes the selected steps. Hereinafter, the specific content of each process is demonstrated. In the following description, it goes without saying that the set temperature can be different for each process, and the set time can be different for each process.

≪予洗工程≫
予洗工程は、薬液を投入しない水で、被洗浄物をシャワー洗浄する工程である。具体的には、まず、液位検出器が設定水位を検出するまで、給水手段５により液貯留部４に給水する。その後、循環ポンプ２４を作動させて、液貯留部４からの水を、循環配管２３および支持部材１３を介して洗浄ノズル３へ供給し、洗浄ノズル３を回転させながら、洗浄ノズル３のノズル孔から被洗浄物に噴射する。これにより、被洗浄物は、上下の洗浄ノズル３から噴射される水で洗浄される。各洗浄ノズル３から噴射された水は、洗浄槽２下部の液貯留部４へ戻される。設定時間だけ水を循環させた後、循環ポンプ２４を停止して、排水手段６により貯留水を排水する。なお、予洗工程では、本実施例では常温水を循環させるが、場合により第一ヒータ１０などにより設定温度に加熱した温水を循環させてもよい。 ≪Prewash process≫
The pre-washing process is a process of shower-cleaning an object to be cleaned with water into which no chemical solution is added. Specifically, first, water is supplied to the liquid storage unit 4 by the water supply means 5 until the liquid level detector detects the set water level. Thereafter, the circulation pump 24 is operated to supply water from the liquid reservoir 4 to the cleaning nozzle 3 via the circulation pipe 23 and the support member 13, and while rotating the cleaning nozzle 3, the nozzle hole of the cleaning nozzle 3 is rotated. Is sprayed onto the object to be cleaned. Thus, the object to be cleaned is cleaned with water sprayed from the upper and lower cleaning nozzles 3. The water sprayed from each cleaning nozzle 3 is returned to the liquid reservoir 4 below the cleaning tank 2. After circulating water for the set time, the circulation pump 24 is stopped and the stored water is drained by the drainage means 6. In the pre-washing step, normal temperature water is circulated in the present embodiment, but in some cases, hot water heated to a set temperature by the first heater 10 or the like may be circulated.

≪シャワー洗浄工程≫
シャワー洗浄工程は、薬液（洗剤）を投入した水（洗浄水）で、被洗浄物をシャワー洗浄する工程である。シャワー洗浄工程は、基本的には予洗工程と同様である。そこで、ここでは、シャワー洗浄工程が予洗工程と異なる点について説明する。シャワー洗浄工程では、液貯留部４に設定水位まで水を貯留後、循環ポンプ２４を作動させて、液貯留部４内の貯留水を洗浄ノズル３へ循環供給する。典型的には、この循環中、薬液ポンプ２２を所要時間だけ作動させて、循環手段８による循環水ひいては液貯留部４の貯留水に、薬液を投入して設定濃度の洗浄水とする。さらに、循環ポンプ２４の作動中（または作動前）、第一ヒータ１０を作動させて、液貯留部４内の貯留水を設定温度（たとえば４０℃）まで加熱する。但し、給水路１４または熱水路４２により、温水を給水できる場合には、その温水を利用してもよい。いずれにしても、洗浄水の循環中、第一温度センサ４５の検出温度に基づき第一ヒータ１０を制御して、洗浄水の温度を設定温度に維持する。循環水が設定温度に到達してから、設定時間経過すると、第一ヒータ１０による加熱や循環ポンプ２４による循環を停止する。そして、排水手段６により排水するが、排水せずに、次工程の超音波洗浄工程で、洗浄水を継ぎ足して利用してもよい。 ≪Shower cleaning process≫
The shower cleaning process is a process of shower cleaning an object to be cleaned with water (cleaning water) charged with a chemical solution (detergent). The shower cleaning process is basically the same as the pre-cleaning process. Therefore, here, the difference between the shower cleaning process and the pre-cleaning process will be described. In the shower cleaning process, after the water is stored in the liquid storage unit 4 to the set water level, the circulation pump 24 is operated to circulate and supply the stored water in the liquid storage unit 4 to the cleaning nozzle 3. Typically, during this circulation, the chemical liquid pump 22 is operated for a required time, and the chemical liquid is poured into the circulating water by the circulation means 8 and thus the water stored in the liquid storage section 4 to obtain a set concentration of cleaning water. Furthermore, during the operation of the circulation pump 24 (or before the operation), the first heater 10 is operated to heat the stored water in the liquid storage unit 4 to a set temperature (for example, 40 ° C.). However, when hot water can be supplied through the water supply channel 14 or the hot water channel 42, the hot water may be used. In any case, during the circulation of the cleaning water, the first heater 10 is controlled based on the temperature detected by the first temperature sensor 45 to maintain the temperature of the cleaning water at the set temperature. When the set time elapses after the circulating water reaches the set temperature, heating by the first heater 10 and circulation by the circulation pump 24 are stopped. And although it drains with the drainage means 6, you may add and use washing water at the ultrasonic cleaning process of the next process, without draining.

なお、ここでは第一ヒータ１０で洗浄水を加熱する例を示したが、場合により洗浄水の加熱を省略してもよい。また、設定温度を変えて（あるいは変えずに）、シャワー洗浄工程を複数回行ってもよい。その際、設定温度を変えるごとに、洗浄槽２内の洗浄水を入れ替えてもよいし、入れ替えなくてもよい。 In addition, although the example which heats washing water with the 1st heater 10 was shown here, heating of washing water may be abbreviate | omitted depending on the case. Further, the shower cleaning step may be performed a plurality of times while changing (or not changing) the set temperature. At that time, each time the set temperature is changed, the cleaning water in the cleaning tank 2 may be replaced or may not be replaced.

また、薬液タンク２１および給液路２０のセットを並列に複数備える場合において、シャワー洗浄工程を複数回行う際、途中の回で薬液の種類を変更してもよい。その場合でも、前述したように、本実施例の洗浄器１によれば、薬液ポンプ２２よりも下流の給液路２０に薬液の残留が防止されているので、異なる薬液が不意に混ざり合うおそれがない。また、同じ薬液を用いる場合でも、各回における薬液の残留が防止されるので、回を重ねるごとに薬液濃度が高まり過ぎるおそれもない。 Further, in the case where a plurality of sets of the chemical liquid tank 21 and the liquid supply path 20 are provided in parallel, the type of the chemical liquid may be changed halfway when performing the shower cleaning step a plurality of times. Even in that case, as described above, according to the cleaning device 1 of the present embodiment, since the chemical liquid is prevented from remaining in the liquid supply path 20 downstream of the chemical liquid pump 22, different chemical liquids may be mixed unexpectedly. There is no. Further, even when the same chemical solution is used, the chemical solution is prevented from remaining at each time, so that the concentration of the chemical solution does not increase excessively each time.

≪超音波洗浄工程≫
超音波洗浄工程は、洗浄槽２内において、被洗浄物を液体に浸漬して超音波洗浄する工程である。具体的には、まず、液位検出器が設定水位を検出するまで、給水手段５により液貯留部４に給水する。この際、洗浄槽２内の被洗浄物が水没（つまり被洗浄物を浸漬）するまで、洗浄槽２内に給水する。洗浄槽２内の被洗浄物が水没するのであれば、必ずしも洗浄槽２内の上部まで給水する必要はない。また、シャワー洗浄工程と同様に、必要に応じて、循環ポンプ２４を作動させつつ、薬液供給手段７により、所望の薬液を洗浄槽２内へ投入してもよいし、第一ヒータ１０により、貯留水を設定温度に加熱してもよい。そして、超音波振動子４４を作動させるが、超音波振動子４４の作動は、場合により、洗浄槽２内への給水中（特に少なくとも一部の被洗浄物を浸漬後）や、あるいは洗浄槽２内の貯留液の加熱中において開始してもよい。また、超音波洗浄中、循環ポンプ２４を作動させて、洗浄ノズル３からの水の噴射を併用してもよい。洗浄槽２内の上方に配置された被洗浄物は、場合により超音波が当たり難く洗浄効果が薄れる場合があるが、洗浄ノズル３からのシャワー洗浄を併用することで、洗浄ノズル３からの液体の噴射とそれによる貯留水の流動とにより、すべての被洗浄物を効果的に洗浄することができる。貯留水が設定温度に到達してから、設定時間経過すると、第一ヒータ１０の他、超音波振動子４４や循環ポンプ２４を停止する。そして、排水手段６により排水するが、次工程で、設定温度を上げたシャワー洗浄工程（高温洗浄工程）を実施する場合には、全量を排水せずに、洗浄水の一部のみを排水して残りを利用してもよい。 ≪Ultrasonic cleaning process≫
The ultrasonic cleaning step is a step of ultrasonically cleaning the object to be cleaned in a liquid in the cleaning tank 2. Specifically, first, water is supplied to the liquid storage unit 4 by the water supply means 5 until the liquid level detector detects the set water level. At this time, water is supplied into the cleaning tank 2 until the object to be cleaned in the cleaning tank 2 is submerged (that is, the object to be cleaned is immersed). If the object to be cleaned in the cleaning tank 2 is submerged, it is not always necessary to supply water to the upper part in the cleaning tank 2. Similarly to the shower cleaning step, a desired chemical solution may be introduced into the cleaning tank 2 by the chemical solution supply means 7 while operating the circulation pump 24 as necessary. The stored water may be heated to a set temperature. Then, the ultrasonic vibrator 44 is operated. Depending on the case, the ultrasonic vibrator 44 may be supplied into the cleaning tank 2 (particularly after immersing at least a part of the object to be cleaned) or the cleaning tank. You may start in the heating of the stored liquid in 2. FIG. Further, during the ultrasonic cleaning, the circulation pump 24 may be operated to use water jet from the cleaning nozzle 3 together. The object to be cleaned disposed in the upper part of the cleaning tank 2 may be difficult to be subjected to ultrasonic waves in some cases and the cleaning effect may be diminished. However, the liquid from the cleaning nozzle 3 can be obtained by using shower cleaning from the cleaning nozzle 3 together. All the objects to be cleaned can be effectively cleaned by the injection of the water and the flow of the stored water. When the set time elapses after the stored water reaches the set temperature, the ultrasonic vibrator 44 and the circulation pump 24 are stopped in addition to the first heater 10. Then, the water is drained by the drainage means 6, but in the next process, when a shower cleaning process (high temperature cleaning process) with an increased set temperature is performed, only a part of the cleaning water is drained without draining the entire amount. You can use the rest.

≪濯ぎ工程≫
濯ぎ工程は、予洗工程と同様の工程であり、液貯留部４に水を貯留した後、循環ポンプ２４を作動させて、洗浄ノズル３から水を噴射して、被洗浄物を濯ぐ工程である。この際、第一ヒータ１０により貯留水を設定温度まで加熱してもよい。また、場合により、循環水に薬剤を投入してもよい。設定時間だけ水を循環させた後、循環ポンプ２４を停止する。そして、排水手段６により、液貯留部４から排水する。典型的には、濯ぎ工程を設定回数（少なくとも１回）繰り返す。具体的には、給水手段５による給水と、循環手段８による設定時間の循環と、排水手段６による排水とのセットを設定回数（たとえば２回）繰り返す。 ≪Rinse process≫
The rinsing step is a step similar to the pre-washing step, in which water is stored in the liquid storage unit 4 and then the circulation pump 24 is operated to inject water from the cleaning nozzle 3 to rinse the object to be cleaned. is there. At this time, the stored water may be heated to the set temperature by the first heater 10. Moreover, you may throw a chemical | medical agent into circulating water depending on the case. After circulating water for a set time, the circulation pump 24 is stopped. And it drains from the liquid storage part 4 by the drainage means 6. Typically, the rinsing process is repeated a set number of times (at least once). Specifically, a set of water supply by the water supply means 5, circulation of a set time by the circulation means 8, and drainage by the drainage means 6 is repeated a set number of times (for example, twice).

≪除染工程≫
除染工程は、シャワー洗浄工程と同様の工程であるが、水温が異なる。除染工程では、循環水は、熱水（６５℃以上９５℃以下の高温水）とされる。第一ヒータ１０で熱水まで加熱してもよいが、予め加熱タンク３７において熱水を用意しておき、給水路１４からの給水の代わりに、加熱タンク３７から熱水を給水すれば、運転時間の短縮を図ることができる。除染工程では、被洗浄物に噴射される液体の温度を確実に消毒温度に維持できるように、循環ポンプ２４の出口側にも第一温度センサ４５を設けておき、その温度に基づき第一ヒータ１０を制御するようにしてもよい。なお、除染工程では、所望により、薬液供給手段７により薬液（たとえば潤滑防錆剤および／または乾燥促進剤）を投入してもよい。循環水が設定温度以上である積算時間が設定時間に達すると、第一ヒータ１０や循環ポンプ２４を停止して、排水手段６により排水する。 ≪Decontamination process≫
The decontamination process is the same process as the shower cleaning process, but the water temperature is different. In the decontamination process, the circulating water is hot water (high temperature water of 65 ° C. or more and 95 ° C. or less). The hot water may be heated by the first heater 10, but if hot water is prepared in the heating tank 37 in advance and hot water is supplied from the heating tank 37 instead of the water supply from the water supply path 14, the operation is performed. Time can be shortened. In the decontamination process, a first temperature sensor 45 is also provided on the outlet side of the circulation pump 24 so that the temperature of the liquid sprayed onto the object to be cleaned can be reliably maintained at the disinfection temperature. The heater 10 may be controlled. In the decontamination step, a chemical solution (for example, a lubricating rust preventive agent and / or a drying accelerator) may be added by the chemical solution supply means 7 as desired. When the accumulated time in which the circulating water is equal to or higher than the set temperature reaches the set time, the first heater 10 and the circulation pump 24 are stopped and drained by the draining means 6.

≪乾燥工程≫
乾燥工程は、洗浄槽２内に熱風を吹き込んで、被洗浄物を乾燥させる工程である。具体的には、送風機９を作動させると共に給気弁３２を開放すればよい。また、第二ヒータ１１を作動させることで、洗浄槽２内へ熱風を送り込むことができる。この際、第二温度センサ４６の検出温度に基づき第二ヒータ１１を制御することで、熱風の温度を設定温度に維持することができる。送風機９からの熱風は、第一給気路３１ａ、循環配管２３および支持部材１３を介して、洗浄ノズル３を回転させながら、洗浄ノズル３のノズル孔から噴射される。また、これと並行して、送風機９からの熱風は、第二給気路３１ｂおよびジャケット１２を介して、洗浄槽２内へ供給される。これら熱風は、洗浄槽２の上部の排気路３４から導出され、図示例では、前述したように一部を入れ替えながら送風機９により循環される。設定時間経過すると、第二ヒータ１１や送風機９を停止する。 ≪Drying process≫
The drying process is a process of blowing hot air into the cleaning tank 2 to dry the object to be cleaned. Specifically, the air blower 9 may be operated and the air supply valve 32 may be opened. Moreover, hot air can be sent into the cleaning tank 2 by operating the second heater 11. At this time, the temperature of the hot air can be maintained at the set temperature by controlling the second heater 11 based on the temperature detected by the second temperature sensor 46. Hot air from the blower 9 is jetted from the nozzle hole of the cleaning nozzle 3 while rotating the cleaning nozzle 3 through the first air supply path 31 a, the circulation pipe 23, and the support member 13. In parallel with this, hot air from the blower 9 is supplied into the cleaning tank 2 via the second air supply path 31 b and the jacket 12. These hot air is led out from the exhaust passage 34 at the upper part of the cleaning tank 2 and is circulated by the blower 9 in the illustrated example while replacing a part thereof as described above. When the set time has elapsed, the second heater 11 and the blower 9 are stopped.

このような一連の各工程の終了後、完了工程として、所定操作がなされるまでか設定時間が経過するまで、送風機９を間欠的に運転してもよい。この際、第二ヒータ１１による加熱は行わない。完了工程の実施により、洗浄槽２内の被洗浄物への結露の付着を防止することができる。 After the completion of such a series of steps, the blower 9 may be intermittently operated as a completion step until a predetermined operation is performed or until a set time elapses. At this time, heating by the second heater 11 is not performed. By performing the completion step, it is possible to prevent the condensation from adhering to the object to be cleaned in the cleaning tank 2.
