この種の洗浄器において、洗浄水の使用量を減らすことができれば、単に給水量を削減できるだけでなく、給水に薬液を投入する場合には薬液投入量を削減できる他、給水を加熱して温水とする場合には加熱量を削減することもできる。 In this type of washer, if the amount of washing water used can be reduced, not only can the amount of water supplied be reduced, but if the chemical solution is introduced into the water supply, the amount of chemical solution input can be reduced and If so, the amount of heating can also be reduced.

ところが、洗浄槽下部の液貯留部（貯水槽）の貯水量を単に減らすと、循環ポンプにエアがみを起こすおそれがある。特に、前記特許文献１に開示される洗浄器では、洗浄槽内の下部全体が液貯留部とされ、洗浄ノズルからの噴射液の全量が液面に直に落ちることになり、液貯留部で気泡が生じやすく、その気泡を循環ポンプが吸い込むことでエアがみが生じやすい。そのため、エアがみ防止の観点から、液貯留部の貯水量を削減することができない。 However, if the amount of stored water in the liquid storage portion (water storage tank) at the lower part of the cleaning tank is simply reduced, air may be generated in the circulation pump. In particular, in the cleaning device disclosed in Patent Document 1, the entire lower part in the cleaning tank is a liquid storage portion, and the entire amount of the liquid jetted from the cleaning nozzle falls directly to the liquid level, and the liquid storage portion Air bubbles are easily generated, and the air is likely to be generated when the circulation pump sucks the air bubbles.

液貯留部４の開口縁からのバッフル板５の離隔距離（液貯留部４の左右側面４ａと第一バッフル板５Ａとの間の第一隙間Ｘ１の寸法、あるいは液貯留部４の前後側面４ｂと第二バッフル板５Ｂとの間の第二隙間Ｘ２の寸法）は、次のように設定されるのが好ましい。すなわち、洗浄器１の運転中、洗浄ノズル３からの噴射液は洗浄槽２下部の傾斜面２ａ，２ｂを介して液貯留部４へ流れ込むが、傾斜面２ａ，２ｂからの液流がバッフル板５（５Ａ，５Ｂ）に当たる位置に、バッフル板５を配置（あるいはバッフル板５の大きさを決定）するのが好ましい。これにより、傾斜面２ａ，２ｂから液貯留部４へ流れ込む液体は、各バッフル板５と液貯留部４の側面４ａ，４ｂとの隙間を介して液貯留部４へ供給されることになる。なお、循環ポンプ１４の作動中における液貯留部４の液位に対し、バッフル板５の下端部は、液面よりも下方（つまりバッフル板５の下端部が液中に差し込まれた状態）にあってもよい。 The separation distance of the baffle plate 5 from the opening edge of the liquid storage portion 4 (the dimension of the first gap X1 between the left and right side surfaces 4a of the liquid storage portion 4 and the first baffle plate 5A, or the front and rear side surfaces 4b of the liquid storage portion 4 Of the second gap X2 between the second baffle plate 5B and the second baffle plate 5B is preferably set as follows. That is, during the operation of the washer 1, the jetted liquid from the washing nozzle 3 flows into the liquid storage portion 4 through the inclined surfaces 2a and 2b at the lower part of the washing tank 2, but the liquid flow from the inclined surfaces 2a and 2b is a baffle plate It is preferable to arrange the baffle plate 5 (or to determine the size of the baffle plate 5) at a position where it hits 5 (5A, 5B). As a result, the liquid flowing from the inclined surfaces 2a and 2b into the liquid storage portion 4 is supplied to the liquid storage portion 4 through the gaps between the baffle plates 5 and the side surfaces 4a and 4b of the liquid storage portion 4. The lower end of the baffle plate 5 is lower than the liquid level (that is, the lower end of the baffle plate 5 is inserted into the liquid) with respect to the liquid level of the liquid storage portion 4 during operation of the circulation pump 14 It may be.

洗浄槽２と液貯留部４との間は、網材または多孔板から構成される仕切材１５で仕切られるのが好ましい。たとえば、洗浄槽２と液貯留部４とは、金網またはパンチングメタルから構成される仕切材１５で仕切られる。この場合、この仕切材１５に、バッフル板を保持して設けることができる。具体的には、仕切材１５の上面および／または下面に、仕切材１５と略垂直に（あるいは傾斜させて）各バッフル板５を固定すればよい。 It is preferable to divide between the washing tank 2 and the liquid storage part 4 by the partition material 15 comprised from a mesh material or a perforated panel. For example, the cleaning tank 2 and the liquid storage unit 4 are partitioned by a partition member 15 formed of a wire mesh or punching metal. In this case, the baffle plate can be held on the partition member 15 and provided. Specifically, each baffle plate 5 may be fixed to the upper surface and / or the lower surface of the partition member 15 substantially perpendicularly (or inclined) to the partition member 15.

液貯留部４には、仕切材１５よりも下方に、ストレーナ１６が設けられるのが好ましい。ストレーナ１６の目の粗さは、仕切材１５よりも十分に細かいものが採用される。液貯留部４に設定液位まで給水後、循環手段９を作動させると、液貯留部４の液位は低下するが、その状態において、ストレーナ１６は、液面よりも上方にあってもよいし、液面あるいはそれよりも下方（つまり液中）にあってもよい。ストレーナ１６を比較的上方に配置する場合、液貯留部４に加熱手段１０を設置しやすい。ストレーナ１６を比較的下方（特に液中）に設置する場合、循環ポンプ１４への液中の気泡を除去しやすい。 Preferably, a strainer 16 is provided in the liquid storage portion 4 below the partition member 15. The mesh size of the strainer 16 is sufficiently finer than that of the partition member 15. When the circulation means 9 is operated after supplying water to the liquid storage part 4 to the set liquid level, the liquid level of the liquid storage part 4 decreases, but in that state, the strainer 16 may be above the liquid level May be at or below the level (ie in the liquid). When the strainer 16 is disposed relatively upward, the heating unit 10 can be easily installed in the liquid storage unit 4. When the strainer 16 is installed relatively downward (in particular, in liquid), air bubbles in the liquid to the circulation pump 14 can be easily removed.

給水手段６は、給水路１７を介して、液貯留部４に水を供給する。給水路１７には、給水弁１８が設けられている。給水弁１８を開けることで、液貯留部４に給水することができる。図示例では、洗浄槽２に給水路１７を接続することで、給水は洗浄槽２を介して液貯留部４に供給されるが、液貯留部４に給水路１７を接続することで、給水は液貯留部４に直接に供給されてもよい。なお、給水手段６は、複数種の水（たとえば水道水、温水、膜濾過水など）から選択された水を供給可能に構成されてもよい。 The water supply unit 6 supplies water to the liquid storage unit 4 through the water supply path 17. A water supply valve 18 is provided in the water supply passage 17. By opening the water supply valve 18, the liquid storage portion 4 can be supplied with water. In the illustrated example, the water supply is supplied to the liquid storage unit 4 via the cleaning tank 2 by connecting the water supply path 17 to the cleaning tank 2, but the water supply is supplied by connecting the water supply path 17 to the liquid storage unit 4. May be supplied directly to the liquid reservoir 4. In addition, the water supply means 6 may be comprised so that supply of the water selected from multiple types of water (for example, tap water, warm water, membrane filtration water etc.) is possible.

排水手段７は、液貯留部４から排水路１９を介して水を排出する。排水路１９には、排水弁２０が設けられている。排水弁２０を開けることで、洗浄槽２や液貯留部４から排水することができる。 The drainage means 7 drains water from the liquid storage unit 4 via the drainage path 19. A drainage valve 20 is provided in the drainage channel 19. By opening the drain valve 20, it is possible to drain water from the washing tank 2 and the liquid storage unit 4.

薬液供給手段８は、薬液タンク２１から給液路２２を介して、液貯留部４に薬液を供給する。給液路２２には、薬液ポンプ２３が設けられている。薬液ポンプ２３を作動させることで、設定量の薬液を液貯留部４に供給することができる。図示例では、液貯留部４に給液路２２を接続することで、薬液は液貯留部４に直接に供給されるが、洗浄槽２に給液路２２を接続することで、薬液は洗浄槽２を介して液貯留部４に供給されてもよい。なお、薬液供給手段８は、複数種の薬液（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）から選択された薬液を供給可能に構成されてもよい。 The chemical solution supply unit 8 supplies the chemical solution from the chemical solution tank 21 to the liquid storage unit 4 through the liquid supply path 22. A chemical solution pump 23 is provided in the liquid supply passage 22. By operating the drug solution pump 23, a set amount of drug solution can be supplied to the liquid storage unit 4. In the illustrated example, the chemical solution is supplied directly to the liquid storage unit 4 by connecting the liquid supply passage 22 to the liquid storage unit 4, but the chemical solution is cleaned by connecting the liquid supply passage 22 to the cleaning tank 2. The liquid reservoir 4 may be supplied via the tank 2. The chemical solution supply unit 8 may be configured to be able to supply a chemical solution selected from a plurality of types of chemical solutions (for example, alkaline detergents, enzyme-containing detergents, lubricating rust inhibitors, drying accelerators, etc.).

循環手段９は、液貯留部４の液体を洗浄ノズル３へ循環供給する。具体的には、循環手段９は、循環配管２４と循環ポンプ１４とを備える。循環配管２４は、液貯留部４から各洗浄ノズル３の支持部材１１への配管であり、その途中に循環ポンプ１４が設けられている。なお、図示例では、循環配管２４の内、液貯留部４から循環ポンプ１４への配管は、上流側において、排水路１９と共通管路とされている。また、循環配管２４の内、循環ポンプ１４の出口側には、逆止弁２５が設けられている。循環ポンプ１４を作動させると、液貯留部４の液体を、循環配管２４および支持部材１１を介して洗浄ノズル３へ供給して噴射し、洗浄槽２下部の液貯留部４へ戻すことができる。 The circulation means 9 circulates and supplies the liquid in the liquid reservoir 4 to the cleaning nozzle 3. Specifically, the circulation means 9 includes a circulation pipe 24 and a circulation pump 14. The circulation pipe 24 is a pipe from the liquid reservoir 4 to the support member 11 of each cleaning nozzle 3, and a circulation pump 14 is provided in the middle thereof. In the illustrated example, in the circulation pipe 24, the pipe from the liquid reservoir 4 to the circulation pump 14 is a common pipe and the drainage path 19 on the upstream side. Further, a check valve 25 is provided on the outlet side of the circulation pump 14 in the circulation pipe 24. When the circulation pump 14 is operated, the liquid in the liquid storage unit 4 can be supplied to the cleaning nozzle 3 via the circulation pipe 24 and the support member 11 and jetted, and can be returned to the liquid storage unit 4 in the lower part of the cleaning tank 2 .

加熱手段１０は、本実施例では、液貯留部４に設けられたヒータ２６から構成される。ヒータ２６は、図示例では電気ヒータであるが、場合により蒸気ヒータであってもよい。電気ヒータの場合、典型的にはオンオフ制御されるが、場合により出力を調整されてもよい。一方、蒸気ヒータの場合、蒸気管内に蒸気が供給可能とされ、蒸気の凝縮水は蒸気トラップを介して外部へ排出される。そして、給蒸路に設けた給蒸弁の開閉または開度が制御される。 The heating means 10 is comprised from the heater 26 provided in the liquid storage part 4 in the present Example. The heater 26 is an electric heater in the illustrated example, but may be a steam heater as the case may be. In the case of an electric heater, on / off control is typically performed, but the output may be adjusted in some cases. On the other hand, in the case of the steam heater, steam can be supplied into the steam pipe, and condensed water of the steam is discharged to the outside through the steam trap. And the opening / closing or opening degree of the steam supply valve provided in the steam supply path is controlled.

液貯留部４には、液位検出器２７が設けられる。液位検出器２７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や洗浄槽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。 The liquid reservoir 4 is provided with a liquid level detector 27. The liquid level detector 27 is not particularly limited in its configuration, and is constituted of, for example, a pressure sensor installed at the bottom of the liquid reservoir 4. In this case, according to the liquid level in the liquid storage part 4 or the cleaning tank 2, the liquid level is grasped using the change of the water pressure.

液貯留部４には、温度センサ２８が設けられる。温度センサ２８の検出温度に基づきヒータ２６を制御することで、液貯留部４の貯留液の温度を調整することができる。 The liquid storage unit 4 is provided with a temperature sensor 28. By controlling the heater 26 based on the temperature detected by the temperature sensor 28, the temperature of the stored liquid in the liquid storage portion 4 can be adjusted.

その他、洗浄器１には、所望により、超音波振動子２９が設けられる。図示例では、洗浄槽２下部の左右の傾斜面２ａに、それぞれ超音波振動子２９が設けられている。超音波振動子２９は、超音波発振器に接続されて、発振を制御される。被洗浄物を浸漬した状態で超音波振動子２９を作動させることで、被洗浄物を超音波洗浄することができる。 In addition, the ultrasonic transducer 29 is provided in the cleaning device 1 as desired. In the illustrated example, ultrasonic transducers 29 are respectively provided on the left and right inclined surfaces 2 a in the lower part of the cleaning tank 2. The ultrasonic transducer 29 is connected to an ultrasonic oscillator to control oscillation. By operating the ultrasonic transducer 29 in a state in which the object to be cleaned is immersed, the object to be cleaned can be ultrasonically cleaned.

制御手段は、前記各手段６〜１０の他、液位検出器２７および温度センサ２８などに接続された制御器（図示省略）である。具体的には、給水弁１８、排水弁２０、薬液ポンプ２３、循環ポンプ１４、ヒータ２６、超音波発振器（２９）、液位検出器２７および温度センサ２８などは、制御器に接続されている。そして、制御器は、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を図る。この際、少なくとも、次に述べるシャワー洗浄動作を実行可能とされる。 The control means is a controller (not shown) connected to the liquid level detector 27 and the temperature sensor 28 in addition to the respective means 6 to 10 described above. Specifically, the feed water valve 18, the drainage valve 20, the chemical solution pump 23, the circulation pump 14, the heater 26, the ultrasonic oscillator (29), the liquid level detector 27, the temperature sensor 28, etc. are connected to the controller . Then, the controller cleans the objects to be cleaned in the cleaning tank 2 in accordance with a predetermined procedure (program). At this time, at least a shower cleaning operation described below can be performed.

シャワー洗浄動作では、液貯留部４内に液体を貯留し、その液体を循環手段９により洗浄ノズル３へ循環供給して、洗浄ノズル３から被洗浄物に噴射する。具体的には、まず、液位検出器２７が設定水位を検出するまで、給水手段６により液貯留部４に給水する。のちに循環ポンプ１４を作動させると水位は下がるので、初期給水時の設定水位は、仕切材１５よりも上方にあってもよく、たとえば傾斜面２ａの上端縁付近まで給水される。この場合でも、循環ポンプ１４の作動中の水位は、液貯留部４内に収まることになる。 In the shower cleaning operation, the liquid is stored in the liquid storage unit 4, and the liquid is circulated and supplied to the cleaning nozzle 3 by the circulation unit 9, and is jetted from the cleaning nozzle 3 to the object to be cleaned. Specifically, water is supplied to the liquid reservoir 4 by the water supply means 6 until the liquid level detector 27 detects the set water level. When the circulation pump 14 is operated later, the water level drops, so the set water level at the time of initial water supply may be above the partition member 15, and for example, water is supplied near the upper end edge of the inclined surface 2a. Even in this case, the water level during operation of the circulation pump 14 falls within the liquid reservoir 4.

液貯留部４への給水後、必要に応じて、薬液供給手段８により液貯留部４に所望の薬液を投入する。薬液供給手段８による薬液は、給水手段６による給水に対し、設定濃度になるように設定量だけ投入される。さらに、同じく必要に応じて、加熱手段１０により、液貯留部４内の貯留水を設定温度まで加熱する。薬液の投入や貯留水の加熱は、循環手段９の作動前に限らず、循環手段９の作動中に行ってもよい。 After water supply to the liquid storage unit 4, a desired chemical solution is introduced into the liquid storage unit 4 by the chemical solution supply unit 8 as necessary. The chemical solution supplied by the chemical solution supply means 8 is supplied to the water supply by the water supply means 6 by a set amount so as to have a set concentration. Furthermore, the storage water in the liquid storage unit 4 is heated to the set temperature by the heating unit 10 as needed. The introduction of the chemical solution and the heating of the stored water may be performed not only before the operation of the circulation unit 9 but also during the operation of the circulation unit 9.

いずれにしても、液貯留部４に所望量の液体を貯留した状態で、循環ポンプ１４を作動させて、貯留液を循環配管２４および支持部材１１を介して洗浄ノズル３へ供給して噴射し、洗浄ノズル３を回転させながら被洗浄物を洗浄する。そして、各洗浄ノズル３から噴射された液体は、洗浄槽２下部の液貯留部４へ戻される。所定の終了条件（たとえば設定時間の経過）を満たすと、循環ポンプ１４を停止して、液貯留部４内の液体を排水手段７により排出する。 In any case, in a state where a desired amount of liquid is stored in the liquid storage portion 4, the circulating pump 14 is operated to supply the stored liquid to the cleaning nozzle 3 via the circulation pipe 24 and the support member 11 and inject it. The object to be cleaned is cleaned while rotating the cleaning nozzle 3. Then, the liquid ejected from each cleaning nozzle 3 is returned to the liquid storage portion 4 in the lower portion of the cleaning tank 2. When a predetermined termination condition (for example, an elapse of a set time) is satisfied, the circulation pump 14 is stopped, and the liquid in the liquid storage unit 4 is discharged by the drainage means 7.

典型的には、このようなシャワー洗浄動作を繰り返して、被洗浄物を洗浄および濯ぎする。たとえば、薬液を投入しない常温水による予備洗浄、所望により洗剤を投入した温水による本洗浄（典型的には複数回）、所望により濯ぎ剤を投入した温水による濯ぎ洗浄（典型的には複数回）などが順次になされる。 Typically, such shower washing operation is repeated to wash and rinse the material to be washed. For example, pre-washing with cold water without adding chemical solution, main washing with warm water optionally containing detergent (typically multiple times), rinsing with warm water optionally containing rinsing agent (typically multiple times) Etc. are made sequentially.

本実施例の洗浄器１によれば、洗浄ノズル３から噴射された液体は、洗浄槽２下部の傾斜面２ａ，２ｂを介して、液貯留部４へ流れ込むことになる。液貯留部４の開口部には、液貯留部４の開口縁から内側へ隙間をあけてバッフル板５が設けられているので、傾斜面２ａ，２ｂを介して液貯留部４へ流れ込む液体は、液貯留部４への落水位置を制限されることになる。特に、本実施例では、バッフル板５は液貯留部４の開口縁の全周（全辺）と対向して設けられている（つまり液貯留部４の開口部の内側に連続的に設けられている）ので、各傾斜面２ａ，２ｂから液貯留部４へ流れ込む液体による気泡の発生位置は、液貯留部４の壁側に限定されることになる。 According to the washer 1 of the present embodiment, the liquid jetted from the washing nozzle 3 flows into the liquid reservoir 4 through the inclined surfaces 2a and 2b at the lower part of the washing tank 2. Since the baffle plate 5 is provided at the opening of the liquid storage portion 4 with a gap from the opening edge of the liquid storage portion 4 to the inside, the liquid flowing into the liquid storage portion 4 through the inclined surfaces 2a and 2b is The position of the water falling to the liquid storage unit 4 is limited. In particular, in the present embodiment, the baffle plate 5 is provided to face the entire circumference (all sides) of the opening edge of the liquid storage portion 4 (that is, continuously provided inside the opening of the liquid storage portion 4). Therefore, the generation position of air bubbles by the liquid flowing from the inclined surfaces 2 a and 2 b into the liquid storage unit 4 is limited to the wall side of the liquid storage unit 4.

このようにして、液貯留部４内での気泡の発生位置を限定することで、液貯留部４での気泡の発生を抑え、循環ポンプ１４でのエアがみを防止することができる。なお、洗浄ノズル３から噴射された液体は、傾斜面２ａ，２ｂに落ちる以外に、洗浄槽２の平面視中央部では傾斜面２ａ，２ｂを介さずに液貯留部４に落ち得るが、傾斜面２ａ，２ｂを流れ落ちる液流ほどの水量はなく、気泡を発生させる要因としては小さい。 Thus, by limiting the generation position of the air bubble in the liquid storage portion 4, the generation of the air bubble in the liquid storage portion 4 can be suppressed, and the air spot in the circulation pump 14 can be prevented. The liquid jetted from the cleaning nozzle 3 may fall to the liquid storage portion 4 without passing through the inclined surfaces 2a and 2b in the central portion in plan view of the cleaning tank 2 other than falling to the inclined surfaces 2a and 2b. There is no amount of water such as liquid flowing down the surfaces 2a and 2b, which is small as a factor for generating air bubbles.

さらに、本実施例では、液貯留部４には、仕切材１５よりも下方にストレーナ１６が設けられる。ストレーナ１６を設けることで、液中の夾雑物を除去できると共に、液中の気泡の除去も図ることができる。これにより、循環ポンプ１４でのエアがみを一層確実に防止することができる。 Furthermore, in the present embodiment, the liquid storage portion 4 is provided with a strainer 16 below the partition member 15. By providing the strainer 16, contaminants in the liquid can be removed, and bubbles in the liquid can also be removed. Thus, air leakage at the circulation pump 14 can be more reliably prevented.

このようにして、液貯留部４での気泡の発生を抑えることで、循環ポンプ１４に気泡が到達する量を減少させることができる。その分だけ、洗浄器１は、より低水位で運転可能となり、初期給水量（洗浄器１全体の保有水量）を削減することができる。そして、給水量を削減することは、薬液投入量や加熱量の削減にもつながるので、ランニングコストの低減を図ることができる。 Thus, by suppressing the generation of air bubbles in the liquid storage portion 4, the amount of air bubbles reaching the circulation pump 14 can be reduced. By that amount, the washer 1 can be operated at a lower water level, and the initial water supply amount (the amount of water held by the entire washer 1) can be reduced. And since the reduction of the amount of water supply leads to the reduction of the amount of chemical solution input and the amount of heating, the running cost can be reduced.

ところで、液貯留部４の底面には、液貯留部４の液体を洗浄ノズル３へ循環供給する循環口４ｃ（循環ポンプ１４の吸込口）が設けられる。この循環口４ｃは、平面視において、液貯留部４の中心部に設けられてもよいが、中心から偏心した位置に設けられてもよい。偏心して設けられる場合、バッフル板５は、液貯留部４の循環口４ｃに近い位置のみ設けられてもよい。 By the way, a circulation port 4 c (suction port of the circulation pump 14) for circulating and supplying the liquid of the liquid storage unit 4 to the cleaning nozzle 3 is provided on the bottom of the liquid storage unit 4. The circulation port 4c may be provided at the central portion of the liquid storage portion 4 in a plan view, but may be provided at a position eccentric from the center. If the baffle plate 5 is provided eccentrically, the baffle plate 5 may be provided only at a position close to the circulation port 4 c of the liquid storage portion 4.

たとえば、図３では、循環口４ｃは、液貯留部４の前方部に設けられる。この場合、液貯留部４の前後に設けられた第二バッフル板５Ｂの内、循環口４ｃに近い前方の第二バッフル板５Ｂは設置するが、循環口４ｃから遠い後方の第二バッフル板５Ｂの設置は省略してもよい。また、液貯留部４の左右に設けられた第一バッフル板５Ａは、それぞれ前後方向へ沿って設けられるが、循環口４ｃに近い前方部（たとえば前半分）にのみ設け、循環口４ｃから遠い後方部（たとえば後半分）の設置は省略してもよい。循環口４ｃに近い位置にはバッフル板５を設けることで、気泡の発生を抑えて、循環ポンプ１４でのエアがみを防止することができる。一方、循環口４ｃから遠い位置には、バッフル板５を設けなくても、循環口４ｃへ到達するまでの距離があるので、その間に気泡の消滅が図られる。 For example, in FIG. 3, the circulation port 4 c is provided in the front portion of the liquid reservoir 4. In this case, of the second baffle plates 5B provided on the front and back of the liquid storage portion 4, the second baffle plate 5B in the front near the circulation port 4c is installed, but the second baffle plate 5B in the rear far from the circulation port 4c The installation of may be omitted. The first baffle plates 5A provided on the left and right of the liquid storage portion 4 are provided along the longitudinal direction, but provided only in the front portion (for example, the front half) near the circulation port 4c and far from the circulation port 4c The installation of the rear part (for example the rear half) may be omitted. By providing the baffle plate 5 at a position close to the circulation port 4c, it is possible to suppress the generation of air bubbles and to prevent the air from being scattered by the circulation pump 14. On the other hand, even if the baffle plate 5 is not provided at a position far from the circulation port 4c, since there is a distance to reach the circulation port 4c, the bubbles are eliminated.

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、被洗浄物が収容される洗浄槽２と、この洗浄槽２内の被洗浄物へ液体を噴射する洗浄ノズル３と、洗浄槽２の底面と連接された液貯留部４とを備え、液貯留部４の開口部には、液貯留部４の開口縁から所定間隔をあけてバッフル板５が設けられているのであれば、その他の構成は、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, but can be appropriately changed. In particular, it comprises a cleaning tank 2 in which the object to be cleaned is stored, a cleaning nozzle 3 for injecting a liquid onto the object to be cleaned in the cleaning tank 2, and a liquid reservoir 4 connected to the bottom of the cleaning tank 2. If the baffle plate 5 is provided at the opening of the liquid storage portion 4 at a predetermined interval from the opening edge of the liquid storage portion 4, the other configuration can be appropriately changed.

たとえば、洗浄槽２および／または液貯留部４の平面視形状は、略矩形状に限らず、円形または楕円形の他、矩形以外の多角形状などであってもよい。その場合も、好ましくは、洗浄槽２の底面は、液貯留部４の開口縁に近づくにつれて下方へ傾斜すると共に、液貯留部４の開口縁の全周または全辺と連接されている。そして、バッフル板５は、液貯留部４の開口縁の全周または全辺と対向して設けられるのが好ましい。また、液貯留部４の底面の中心より偏心した位置に、洗浄ノズル３への循環口４ｃを設ける場合には、バッフル板５は、液貯留部４の循環口４ｃに近い位置のみ設けられてもよい。 For example, the plan view shape of the cleaning tank 2 and / or the liquid storage portion 4 is not limited to a substantially rectangular shape, and may be a circular shape or an elliptical shape, or a polygonal shape other than a rectangular shape. Also in this case, preferably, the bottom surface of the cleaning tank 2 inclines downward as it approaches the opening edge of the liquid storage portion 4 and is connected to the entire circumference or all sides of the opening edge of the liquid storage portion 4. The baffle plate 5 is preferably provided to face the entire periphery or all sides of the opening edge of the liquid storage portion 4. Further, when the circulation port 4c to the cleaning nozzle 3 is provided at a position eccentric to the center of the bottom surface of the liquid storage portion 4, the baffle plate 5 is provided only at a position near the circulation port 4c of the liquid storage portion 4 It is also good.

さらに、前記実施例において、洗浄後の被洗浄物を乾燥可能に、送風機をさらに備えてもよい。この場合、洗浄後の濡れた被洗浄物は、洗浄槽２へ供給される温風により乾燥を図られる。 Furthermore, in the above embodiment, a fan may be further provided so as to be able to dry the washed object. In this case, the wet object to be cleaned after the cleaning can be dried by the warm air supplied to the cleaning tank 2.
