Hereinafter, the specific content of each process is demonstrated.

≪予洗工程≫
予洗工程は、薬液を投入しない水で、被洗浄物を洗浄する工程である。具体的には、まず、給水弁２４を開けて、液貯留部３に給水する。液貯留部３に設定水位（たとえば図１の液位Ｘ）まで水が貯留されると、液位検出器によりそれを検知して給水弁２４を閉じる。その後、循環ポンプ６を作動させて、液貯留部３からの水を、矩形ダクト５および支持部材１１を介して洗浄ノズル４へ供給し、洗浄ノズル４を回転させながら、洗浄ノズル４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４から噴射される水で洗浄される。各洗浄ノズル４から噴射された水は、洗浄槽２下部の液貯留部３へ戻される。設定時間だけ水を循環させた後、循環ポンプ６を停止する。そして、排水弁１４を開けて液貯留部３から排水し、排水完了後には排水弁１４を閉じる。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７などにより所定温度に加熱した温水を循環させてもよい。 ≪Prewash process≫
The pre-washing step is a step of washing the object to be washed with water without adding a chemical solution. Specifically, first, the water supply valve 24 is opened to supply water to the liquid storage unit 3. When water is stored in the liquid storage unit 3 up to a set water level (for example, the liquid level X in FIG. 1), it is detected by the liquid level detector and the water supply valve 24 is closed. Thereafter, the circulation pump 6 is operated to supply water from the liquid reservoir 3 to the cleaning nozzle 4 through the rectangular duct 5 and the support member 11, and while rotating the cleaning nozzle 4, the nozzle hole of the cleaning nozzle 4 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 4. The water sprayed from each cleaning nozzle 4 is returned to the liquid storage section 3 below the cleaning tank 2. After circulating water for the set time, the circulation pump 6 is stopped. And the drain valve 14 is opened, it drains from the liquid storage part 3, and the drain valve 14 is closed after drainage completion. In the pre-washing step, normal temperature water is circulated in the present embodiment, but in some cases, hot water heated to a predetermined temperature by the first heater 7 or the like may be circulated.

≪洗浄工程≫
洗浄工程は、薬液（洗剤）を投入した水（洗浄液）で、被洗浄物を洗浄する工程である。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、洗浄工程が予洗工程と異なる点について説明する。洗浄工程では、液貯留部３に設定水位まで水を貯留後、薬液ポンプ２７を作動させて、液貯留部３内の貯留水に洗剤を投入する。さらに、第一ヒータ７を作動させて、液貯留部３内の貯留水を設定温度（たとえば４０℃）まで加熱する。但し、循環ポンプ６を作動させながら、液貯留部３内の貯留水を設定温度まで加熱してもよい。また、給水路２２または熱水路４０により、設定温度の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、液貯留部３内に洗浄液を準備した後、循環ポンプ６を作動させて、被洗浄物を洗浄液により洗浄する。洗浄液の循環中、第一温度センサ４３の検出温度に基づき第一ヒータ７を制御して、洗浄液の温度を設定温度に維持する。設定時間だけ洗浄液を循環させた後、循環ポンプ６を停止する。そして、排水弁１４を開けて液貯留部３から排水し、排水完了後には排水弁１４を閉じる。なお、設定温度を変えて、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内の洗浄液を入れ替えてもよいし、入れ替えなくてもよい。 ≪Cleaning process≫
The cleaning process is a process of cleaning the object to be cleaned with water (cleaning liquid) charged with a chemical liquid (detergent). The cleaning process is basically the same as the pre-cleaning process. Therefore, here, the difference between the cleaning process and the pre-cleaning process will be described. In the washing process, after the water is stored in the liquid storage unit 3 to the set water level, the chemical liquid pump 27 is operated to supply the detergent to the stored water in the liquid storage unit 3. Furthermore, the 1st heater 7 is operated and the stored water in the liquid storage part 3 is heated to preset temperature (for example, 40 degreeC). However, the stored water in the liquid storage unit 3 may be heated to a set temperature while the circulation pump 6 is operated. Moreover, when the hot water of preset temperature can be supplied with the water supply path 22 or the hot water path 40, you may utilize the hot water. In any case, after preparing the cleaning liquid in the liquid storage unit 3, the circulating pump 6 is operated to clean the object to be cleaned with the cleaning liquid. During the circulation of the cleaning liquid, the first heater 7 is controlled based on the temperature detected by the first temperature sensor 43 to maintain the temperature of the cleaning liquid at the set temperature. After circulating the cleaning liquid for the set time, the circulation pump 6 is stopped. And the drain valve 14 is opened, it drains from the liquid storage part 3, and the drain valve 14 is closed after drainage completion. In addition, you may perform a washing | cleaning process in multiple times, changing preset temperature. At that time, each time the set temperature is changed, the cleaning liquid in the cleaning tank 2 may be replaced or may not be replaced.

≪超音波洗浄工程≫
超音波洗浄工程は、被洗浄物を超音波洗浄する工程である。具体的には、まず、給水弁２４を開けて、洗浄槽２内に給水する。この際、洗浄槽２内の被洗浄物が水没するまで、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。洗浄槽２内に所望水位まで水が貯留されると、液位検出器によりそれを検知して給水弁２４を閉じる。その後、超音波振動子４２を作動させることで、被洗浄物を超音波洗浄する。この際、循環ポンプ６を作動させて、洗浄ノズル４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４からのジェット洗浄を併用することで、洗浄ノズル４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。なお、超音波洗浄工程では、洗浄工程と同様に、貯留液に薬液を混入してもよいし、第一ヒータ７により貯留液を所望温度に加熱してもよい。設定時間だけ超音波洗浄を行った後、超音波振動子４２などを停止する。そして、排水弁１４を開けて洗浄槽２および液貯留部３から排水し、排水完了後には排水弁１４を閉じる。 ≪Ultrasonic cleaning process≫
The ultrasonic cleaning step is a step of ultrasonically cleaning the object to be cleaned. Specifically, first, the water supply valve 24 is opened to supply water into the cleaning tank 2. At this time, water is supplied into the cleaning tank 2 until the object to be cleaned in the cleaning tank 2 is submerged. 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. When water is stored in the washing tank 2 to a desired water level, it is detected by the liquid level detector and the water supply valve 24 is closed. Thereafter, the ultrasonic vibrator 42 is operated to ultrasonically clean the object to be cleaned. At this time, the circulation pump 6 may be operated to use water jet from the cleaning nozzle 4 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 4 can be obtained by using jet cleaning from the cleaning nozzle 4 together. All the objects to be cleaned can be effectively cleaned by the injection of the water and the flow of the stored water. In the ultrasonic cleaning process, similarly to the cleaning process, a chemical solution may be mixed into the stored liquid, or the stored liquid may be heated to a desired temperature by the first heater 7. After performing ultrasonic cleaning for a set time, the ultrasonic vibrator 42 and the like are stopped. And the drain valve 14 is opened, it drains from the washing tank 2 and the liquid storage part 3, and the drain valve 14 is closed after drainage completion.

≪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３に水を貯留した後、循環ポンプ６を作動させて、洗浄ノズル４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７により貯留水を設定温度まで加熱しておいてもよい。また、場合により、貯留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６を停止する。そして、排水弁１４を開けて液貯留部３から排水し、排水完了後には排水弁１４を閉じる。 ≪Rinse process≫
The rinsing step is a step similar to the pre-washing step, in which water is stored in the liquid storage unit 3 and then the circulation pump 6 is operated to inject water from the cleaning nozzle 4 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 7. Moreover, you may throw a chemical | medical agent into stored water depending on the case. After circulating water for the set time, the circulation pump 6 is stopped. And the drain valve 14 is opened, it drains from the liquid storage part 3, and the drain valve 14 is closed after drainage completion.

≪除染工程≫
除染工程も、基本的には予洗工程と同様であるが、水温が異なる。除染工程では、循環水は、熱水（８０℃以上１００℃未満の高温水）とされる。第一ヒータ７で熱水まで加熱してもよいが、予め加熱タンク３５において熱水を用意しておき、給水路２２からの給水の代わりに、加熱タンク３５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６の出口側にも第一温度センサ４３を設けておき、その温度に基づき第一ヒータ７を制御するようにしてもよい。なお、除染工程後、所望により、仕上げ工程を行ってもよい。仕上げ工程は、前記洗浄工程と同様であるが、洗剤の代わりに潤滑防錆剤および／または乾燥促進剤を用いる点が異なる。 ≪Decontamination process≫
The decontamination process is basically the same as the prewash process, but the water temperature is different. In the decontamination process, the circulating water is hot water (high-temperature water of 80 ° C. or more and less than 100 ° C.). The hot water may be heated by the first heater 7, but if hot water is prepared in the heating tank 35 in advance and hot water is supplied from the heating tank 35 instead of the water supply from the water supply path 22, the operation is performed. Time can be shortened. In the decontamination process, a first temperature sensor 43 is also provided on the outlet side of the circulation pump 6 so that the temperature of the liquid sprayed onto the object to be cleaned can be reliably maintained at the disinfection temperature. The heater 7 may be controlled. In addition, after a decontamination process, you may perform a finishing process if desired. The finishing process is the same as the cleaning process except that a lubricating rust inhibitor and / or a drying accelerator is used instead of the detergent.

≪乾燥工程≫
乾燥工程は、被洗浄物を熱風により乾燥させる工程である。具体的には、送風機８を作動させると共に給気弁３０を開放すればよい。また、第二ヒータ９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４４の検出温度に基づき第二ヒータ９を制御することで、熱風の温度を所定温度に維持することができる。送風機８からの熱風は、第一給気路２９ａ、矩形ダクト５および支持部材１１を介して、洗浄ノズル４を回転させながら、洗浄ノズル４のノズル孔から噴射される。また、これと並行して、送風機８からの熱風は、第二給気路２９ｂおよびジャケット１０を介して、洗浄槽２内の底部へ供給される。これら熱風は、洗浄槽２の上部の排気路３１から導出され、前述したように一部を入れ替えながら送風機８により循環される。 ≪Drying process≫
The drying step is a step of drying the object to be cleaned with hot air. Specifically, the blower 8 may be operated and the air supply valve 30 may be opened. Moreover, hot air can be sent into the cleaning tank 2 by operating the second heater 9. At this time, the temperature of the hot air can be maintained at a predetermined temperature by controlling the second heater 9 based on the temperature detected by the second temperature sensor 44. Hot air from the blower 8 is jetted from the nozzle hole of the cleaning nozzle 4 while rotating the cleaning nozzle 4 through the first air supply path 29a, the rectangular duct 5 and the support member 11. In parallel with this, hot air from the blower 8 is supplied to the bottom of the cleaning tank 2 via the second air supply passage 29b and the jacket 10. These hot air is led out from the exhaust passage 31 at the upper part of the cleaning tank 2 and is circulated by the blower 8 while replacing a part thereof as described above.

つまり、送風機８および第二ヒータ９の作動により、洗浄槽２内に熱風を循環させることができ、その際、オリフィス３３を介して循環空気の一部を外部へ排出する一方、フィルタ３４を介して送風機８に新規空気を取り込むことで、循環空気の一部の入れ替えが徐々になされる。水分を含んだ空気の外部への排出と、その排出分を補うための新規空気の取り込みにより、洗浄槽２内を乾燥に適した相対湿度に保つことができる。 That is, by operating the blower 8 and the second heater 9, hot air can be circulated in the cleaning tank 2, and at that time, a part of the circulating air is discharged to the outside through the orifice 33, while passing through the filter 34. Then, a part of the circulating air is gradually replaced by taking new air into the blower 8. The inside of the cleaning tank 2 can be maintained at a relative humidity suitable for drying by discharging the moisture-containing air to the outside and taking in the new air to make up the discharged air.

本実施例の洗浄器１によれば、循環ポンプ６から洗浄ノズル４への配管として矩形ダクト５が用いられ、この矩形ダクト５は、一側面を洗浄槽２の一側壁に重ね合わせて設けられる。矩形ダクト５を洗浄槽２の側壁に当接して設けることで、装置幅の削減を図ることができる。矩形ダクト５の幅寸法（前後方向奥行寸法）を延ばすことで、流路断面積を確保することができるから、従来技術と比較して、洗浄器１をコンパクトに構成することができる。また、矩形ダクト５が洗浄槽２の補強材として機能するので、洗浄槽２の薄肉化を図ることができる。さらに、循環ポンプ６から洗浄ノズル４の支持部材１１への配管を最短ルートに設定しやすく、配管の圧力損失の低減を図ることもできる。 According to the cleaning device 1 of the present embodiment, a rectangular duct 5 is used as a pipe from the circulation pump 6 to the cleaning nozzle 4, and this rectangular duct 5 is provided with one side surface overlapped with one side wall of the cleaning tank 2. . By providing the rectangular duct 5 in contact with the side wall of the cleaning tank 2, the width of the apparatus can be reduced. By extending the width dimension (depth dimension in the front-rear direction) of the rectangular duct 5, the cross-sectional area of the flow path can be ensured, so that the cleaning device 1 can be configured more compactly than in the prior art. Further, since the rectangular duct 5 functions as a reinforcing material for the cleaning tank 2, the cleaning tank 2 can be made thinner. Furthermore, it is easy to set the pipe from the circulation pump 6 to the support member 11 of the cleaning nozzle 4 as the shortest route, and the pressure loss of the pipe can be reduced.

なお、矩形ダクト５は、本実施例のように、広い面が洗浄槽２の側壁の外面に当接されるのがよい。これにより、洗浄槽２の側壁からは矩形ダクト５の短辺と対応した寸法だけ突出することになり、洗浄槽２の側壁からの矩形ダクト５の突出量を抑えて、装置幅の削減を図ることができる。また、洗浄槽２の側壁には矩形ダクト５の広い面が当接され、しかも洗浄槽２の側壁を上下に縦断するよう設けられるのがよい。これにより、矩形ダクト５による洗浄槽２の補強材としての機能を一層高めることができ、洗浄槽２の薄肉化を図ることができる。 In addition, the rectangular duct 5 is good to contact | abut the wide surface to the outer surface of the side wall of the washing tank 2 like a present Example. Thereby, it projects from the side wall of the cleaning tank 2 by a dimension corresponding to the short side of the rectangular duct 5, and the amount of protrusion of the rectangular duct 5 from the side wall of the cleaning tank 2 is suppressed, thereby reducing the apparatus width. be able to. Further, it is preferable that a wide surface of the rectangular duct 5 is brought into contact with the side wall of the cleaning tank 2 and that the side wall of the cleaning tank 2 is vertically cut. Thereby, the function as a reinforcement of the washing tank 2 by the rectangular duct 5 can be further enhanced, and the washing tank 2 can be thinned.

また、本実施例の洗浄器１によれば、液貯留部３に第一ヒータ７を設けることで、循環開始前（つまり循環ポンプ６の起動前）に液貯留部３において液体を所望温度に加熱することもできる。 Further, according to the cleaning device 1 of the present embodiment, the liquid heater 3 is provided with the first heater 7, so that the liquid is brought to a desired temperature in the liquid reservoir 3 before the start of circulation (that is, before the circulation pump 6 is started). It can also be heated.

また、本実施例の洗浄器１によれば、送風機８から第二ヒータ９で加熱された熱風は、矩形ダクト５および支持部材１１を介して洗浄ノズル４から噴射されるだけでなく、ジャケット１０を介して洗浄槽２内の下部へも供給される。そして、そのようにして供給された熱風は、洗浄槽２の上部の排気路３１へと導出される。ジャケット１０を介して洗浄槽２内の下部からも熱風を供給し、その熱風の排出口を洗浄槽２の上部に設けることで、洗浄ノズル４からだけ熱風を供給した場合と比較して、洗浄槽２内全体に熱風を通過させることができ、被洗浄物の乾燥を迅速および確実に図ることができる。また、矩形ダクト５および支持部材１１を介した給気流量は、洗浄ノズル４内を乾燥させる程度でよく、ジャケット１０を介した給気流量をメインにすることができるので、配管の圧力損失を低減でき、送風機８の小型化を実現することができる。 Further, according to the cleaning device 1 of the present embodiment, the hot air heated by the second heater 9 from the blower 8 is not only jetted from the cleaning nozzle 4 via the rectangular duct 5 and the support member 11, but also the jacket 10. To the lower part in the cleaning tank 2. The hot air thus supplied is led out to the exhaust path 31 at the upper part of the cleaning tank 2. Compared with the case where hot air is supplied from the lower part in the cleaning tank 2 through the jacket 10 and the hot air discharge port is provided at the upper part of the cleaning tank 2, the hot air is supplied only from the cleaning nozzle 4. Hot air can be passed through the entire tank 2, and the object to be cleaned can be dried quickly and reliably. Further, the air supply flow rate through the rectangular duct 5 and the support member 11 may be such that the inside of the cleaning nozzle 4 is dried, and the air supply flow rate through the jacket 10 can be main. The size of the blower 8 can be reduced.

さらに、本実施例の洗浄器１によれば、加熱タンク３５で加熱された熱水は、洗浄槽２の側壁に設けたジャケット１０を介して液貯留部３へ送られるので、万一、洗浄槽２の扉が開いていても、高温の液体が洗浄槽２外へ飛び散るおそれがなく、安全である。 Further, according to the cleaning device 1 of the present embodiment, the hot water heated in the heating tank 35 is sent to the liquid storage unit 3 through the jacket 10 provided on the side wall of the cleaning tank 2, so that it should be cleaned. Even if the door of the tank 2 is open, there is no risk that high-temperature liquid will be scattered outside the cleaning tank 2, which is safe.

本発明の洗浄器１は、前記実施例の構成に限らず適宜変更可能である。特に、洗浄ノズル４へ流体を供給する矩形ダクト５を備え、この矩形ダクト５の一側面を洗浄槽２の一側壁に当接して設けるのであれば、その他の構成および制御は、適宜に変更可能である。 The cleaning device 1 of the present invention is not limited to the configuration of the above embodiment and can be changed as appropriate. In particular, as long as a rectangular duct 5 for supplying fluid to the cleaning nozzle 4 is provided and one side surface of the rectangular duct 5 is provided in contact with one side wall of the cleaning tank 2, other configurations and controls can be changed as appropriate. It is.

たとえば、前記実施例では、洗浄槽２の一側壁の外面に矩形ダクト５の一側面を重ねて設けたが、場合により、洗浄槽２の一側壁の内面に矩形ダクト５の一側面を重ねて設けてもよい。また、洗浄槽２の側壁にジャケット１０を設ける場合、ジャケット１０内（つまりジャケット１０を構成する内壁と外壁）との間に、矩形ダクト５を設けてもよい。その際、ジャケット１０を構成する内壁と外壁との内、少なくとも一方の壁に、矩形ダクト５の一側面が当接される。 For example, in the above embodiment, one side surface of the rectangular duct 5 is provided on the outer surface of one side wall of the cleaning tank 2, but depending on the case, one side surface of the rectangular duct 5 is overlapped with the inner surface of one side wall of the cleaning tank 2. It may be provided. When the jacket 10 is provided on the side wall of the cleaning tank 2, the rectangular duct 5 may be provided between the jacket 10 (that is, the inner wall and the outer wall constituting the jacket 10). At this time, one side surface of the rectangular duct 5 is brought into contact with at least one of the inner wall and the outer wall constituting the jacket 10.

また、前記実施例では、矩形ダクト５は、洗浄槽２の一側壁にのみ当接して設けたが、場合により、その他の面にも当接して設けてもよい。たとえば、前記実施例において、矩形ダクト５は、洗浄槽２の上面よりも上方へ延出させることに代えて、洗浄槽２の上面にも沿うように設けてもよい。つまり、矩形ダクト５は、洗浄槽２の側壁に当接しつつ、その側壁の下端部から上端部まで延出した後、洗浄槽２の上壁に当接しつつ、その上壁の左右方向中央部まで延出して設けられてもよい。この場合、最上部の洗浄ノズル４の支持部材１１には、矩形ダクト５の内、洗浄槽２の上壁に配置された箇所から流体が供給され、最上部以外の洗浄ノズル４の支持部材１１には、矩形ダクト５の内、洗浄槽２の側壁に配置された箇所から液体が供給されるよう構成できる。また、最上部の洗浄ノズル４の支持部材１１は、洗浄槽２の上壁の中央部から下方へ突出して構成すれば足りる。 In the above embodiment, the rectangular duct 5 is provided in contact with only one side wall of the cleaning tank 2, but may be provided in contact with other surfaces depending on circumstances. For example, in the embodiment, the rectangular duct 5 may be provided along the upper surface of the cleaning tank 2 instead of extending upward from the upper surface of the cleaning tank 2. That is, the rectangular duct 5 is in contact with the side wall of the cleaning tank 2 and extends from the lower end portion to the upper end portion of the side wall, and then is in contact with the upper wall of the cleaning tank 2 while being in the center in the left-right direction of the upper wall. It may be provided to extend. In this case, the fluid is supplied to the support member 11 of the uppermost cleaning nozzle 4 from a portion of the rectangular duct 5 disposed on the upper wall of the cleaning tank 2, and the support member 11 of the cleaning nozzle 4 other than the uppermost cleaning nozzle 4. In the rectangular duct 5, the liquid can be supplied from a place arranged on the side wall of the cleaning tank 2. Further, it is sufficient that the support member 11 of the uppermost cleaning nozzle 4 protrudes downward from the central portion of the upper wall of the cleaning tank 2.

ところで、前記実施例では、矩形ダクト５として、断面ロ形の部材を用いたが、場合により、断面コ形の部材を用いることも考えられる。その場合、断面コ字形状材の開放両端部を洗浄槽２の側壁に当接して、その当接部を長手方向に沿って連続的に側壁と溶接することになる。しかしながら、洗浄槽２の側壁に、溶接により歪みが生じやすい。その点、前記実施例のように、断面ロ形の部材を用いると、その長手方向に離隔したいくつかの箇所でのみ洗浄槽２の側壁に溶接またはねじ止めすれば足り、洗浄槽２の側壁の歪みを防止できる。 By the way, in the said Example, although the cross-sectionally-shaped member was used as the rectangular duct 5, depending on the case, using a U-shaped member is also considered. In that case, both open ends of the U-shaped cross-section material are brought into contact with the side wall of the cleaning tank 2, and the contact portions are continuously welded to the side wall along the longitudinal direction. However, the sidewall of the cleaning tank 2 is likely to be distorted by welding. In that respect, when a member having a cross-sectional shape is used as in the above-described embodiment, it is sufficient to weld or screw the cleaning tank 2 to the side wall of the cleaning tank 2 only at some points separated in the longitudinal direction. Can prevent distortion.

その他、前記実施例において、加熱タンク３５および超音波振動子４２は、場合により省略可能である。 In addition, in the said Example, the heating tank 35 and the ultrasonic transducer | vibrator 42 are omissible depending on the case.

さらに、前記実施例では、被洗浄物は、洗浄槽２内の網棚に対し出し入れされたが、洗浄槽２内に洗浄ラックを出し入れ可能とし、その洗浄ラックの網棚に被洗浄物を収容可能としてもよい。その場合、上下複数段に設けられる洗浄ノズル４（特に最上部および／または最下部の洗浄ノズル４以外の洗浄ノズル４）は、洗浄ラックに設けられる。洗浄ラックには、前記実施例と同様に、一側部に、上下方向に沿って補助材１２が設けられており、その補助材１２に上下複数段にアーム状の支持部材１１が設けられ、各支持部材１１に洗浄ノズル４が回転可能に保持される。そして、洗浄槽２に洗浄ラックを収容した状態で、循環ポンプ６からの液体（または送風機８からの空気）を洗浄ラックの洗浄ノズル４へ供給可能に、洗浄ラックの側の支持部材１１への流体供給口と、洗浄槽２の側の矩形ダクト５からの流体吐出口とが、着脱可能に接続される。たとえば、洗浄ラックの側の補助材１２の下端部と、洗浄槽２の側の矩形ダクト５とが、着脱可能に接続される。なお、洗浄ラックは、下端部にキャスターが設けられたワゴン状とされてもよい。また、前記実施例において洗浄槽２内の上下両端部に設けられた洗浄ノズル４の内、一方または双方は、洗浄ラックに設けるのではなく、洗浄槽２の側に設けられてもよい。 Furthermore, in the said Example, although the to-be-cleaned object was taken in / out with respect to the net shelf in the washing tank 2, a washing rack can be taken in / out in the washing tank 2, and to-be-cleaned object can be accommodated in the net shelf of the washing rack Also good. In this case, the cleaning nozzles 4 (in particular, the cleaning nozzles 4 other than the uppermost and / or lowermost cleaning nozzles 4) provided in a plurality of upper and lower stages are provided in the cleaning rack. As in the previous embodiment, the cleaning rack is provided with an auxiliary material 12 on one side along the vertical direction, and the auxiliary material 12 is provided with arm-like support members 11 in a plurality of upper and lower stages, The cleaning nozzle 4 is rotatably held by each support member 11. And in the state which accommodated the washing rack in the washing tank 2, the liquid (or the air from the air blower 8) from the circulation pump 6 can be supplied to the washing nozzle 4 of the washing rack, and the support member 11 on the washing rack side is supplied. The fluid supply port and the fluid discharge port from the rectangular duct 5 on the cleaning tank 2 side are detachably connected. For example, the lower end portion of the auxiliary material 12 on the cleaning rack side and the rectangular duct 5 on the cleaning tank 2 side are detachably connected. Note that the cleaning rack may have a wagon shape with a caster at the lower end. In the embodiment, one or both of the cleaning nozzles 4 provided at the upper and lower ends of the cleaning tank 2 may be provided on the cleaning tank 2 side instead of being provided in the cleaning rack.
