The ejection nozzles 32 and 34 in the left and right rows communicate with each other through a pair of ejection bubbles located at the same position in the front-rear direction in each row. By being connected to the main pipe 36 via S1, S2, and S3, it is possible to switch and control the supply and cutoff of the cleaning liquid independently for each pair.

光電センサ３５は、上述した配膳車２の検出用ＬＥＤ２６からの投射光を受光したか否かの検出結果を制御盤４４に出力するセンサであり、中央列で最も後方側の噴出ノズル３３ｂから前方側に距離Ｌ１だけ離間した位置に配置されている。なお、作業者Ｍが配膳車２を牽引して洗浄作業部３上を通過移動する際に左右方向の位置合わせが容易となるようガイド部材や目印を設けるとよい。例えば図示するように、左右方向において中央列の噴出ノズル３３や光電センサ３５の中央位置と一致して前後方向に延びるセンターラインＣＬを洗浄作業部３の後方側（進入する側から見て手前側）の床面Ｆに描画しておくとよい。なお、光電センサ３５が通過検知部の一例である。 The photoelectric sensor 35 is a sensor that outputs to the control panel 44 a detection result as to whether or not the light projected from the detection LED 26 of the food delivery cart 2 has been received. is arranged at a position spaced apart by a distance L1 to the side. In addition, it is preferable to provide a guide member or a mark so that when the worker M pulls the food delivery cart 2 and moves through the cleaning work part 3, the alignment in the left-right direction is facilitated. For example, as shown in the figure, the center line CL extending in the front-back direction coincides with the center positions of the ejection nozzles 33 and the photoelectric sensors 35 in the center row in the left-right direction. ) should be drawn on the floor F. Note that the photoelectric sensor 35 is an example of a passage detection unit.

そして、洗浄作業部３が上記のように構成されていることで、配膳車２の各車輪２２，２３，２４が当該洗浄作業部３の上方を通過移動した際には車輪２２，２３，２４の外周全体に渡って洗浄液を噴出して洗浄することが可能となる。例えば、洗浄作業部３の側方断面を表す図４に示すように、配膳車２が外部区画を巡回して誘導車輪２２が汚染状態（図中の網掛け部分参照）となったまま洗浄作業部３上を通過移動した際には、中央列の３つの噴出ノズル３３がそれぞれ適切なタイミングで連携して誘導車輪２２を洗浄する。なお本実施形態の例では、この洗浄作業部３上での配膳車２の通過移動中に人間の作業者Ｍが人力での牽引によってほぼ一定の進行速度Ｖを維持して移動させるものとする。 Since the cleaning unit 3 is configured as described above, when the wheels 22, 23, and 24 of the catering cart 2 pass above the cleaning unit 3, the wheels 22, 23, and 24 It is possible to clean by spraying the cleaning liquid over the entire outer periphery of the. For example, as shown in FIG. 4 showing a side cross-section of the cleaning work unit 3, the food service car 2 tours the external compartment, and the cleaning work is performed while the guide wheels 22 are in a contaminated state (see the shaded portion in the figure). When it passes over the portion 3, the three ejection nozzles 33 in the central row cooperate with each other at appropriate timings to wash the guide wheels 22. As shown in FIG. In the example of the present embodiment, it is assumed that the human worker M moves the food cart 2 while it is moving through the cleaning work section 3 while maintaining a substantially constant progressing speed V by manually pulling the food cart 2 . .

まず、配膳車２が洗浄作業部３上への進入を開始して光電センサ３５が検出用ＬＥＤ２６の投射光を検知した際には、誘導車輪２２が中央列の最も後方側の噴出ノズル３３ｂの真上に位置していることになる。制御盤４４は、この光電センサ３５の検知タイミングですぐに後方側噴出ノズル３３ｂに対応する電磁バルブＣ３を開放制御してそこからの洗浄液の噴出を開始することで、誘導車輪２２の全周のうちの下側範囲を消毒洗浄できる。 First, when the catering cart 2 starts to enter the cleaning work section 3 and the photoelectric sensor 35 detects the projection light of the detection LED 26, the guide wheel 22 moves toward the rearmost ejection nozzle 33b in the central row. It is located directly above. At the detection timing of the photoelectric sensor 35, the control panel 44 immediately opens the electromagnetic valve C3 corresponding to the rear ejection nozzle 33b and starts ejecting the cleaning liquid therefrom. The lower area of our house can be disinfected and washed.

そして引き続き配膳車２の移動に伴い、誘導車輪２２が中央列の後方側から中央→前方側の各噴出ノズル３３ｍ，３３ｆに順次近づいたそれぞれのタイミングで、制御盤４４が対応する各噴出ノズル３３ｍ，３３ｆからの洗浄液の噴出を開始させて誘導車輪２２の他の周範囲を消毒洗浄できる。ここで、中央列の３つの噴出ノズル３３ｆ，３３ｍ，３３ｂは誘導車輪２２の外周長さと同じ距離（＝Ｄπ）の範囲で均等に配置されているので、配膳車２を一度も停止させることなく誘導車輪２２を当該洗浄作業部３上に通過移動させるだけで誘導車輪２２の外周の全周範囲を消毒洗浄できる。 As the catering cart 2 continues to move, the control panel 44 controls the corresponding ejection nozzles 33m at the respective timings when the guide wheels 22 sequentially approach the ejection nozzles 33m and 33f from the rear side of the center row toward the center to the front side. , 33f can be initiated to disinfect other circumferential areas of the guide wheel 22. FIG. Here, the three ejection nozzles 33f, 33m, and 33b in the central row are evenly arranged within the range of the same distance (=Dπ) as the outer circumference of the guide wheel 22. Only by passing the guide wheel 22 over the cleaning work section 3, the entire outer peripheral range of the guide wheel 22 can be disinfected and cleaned.

また制御盤４４が他の電磁バルブＳ１，Ｓ２，Ｓ３に対しても、図５の制御タイムチャートに示すように光電センサ３５の検知タイミングＸを基準とした適切なタイミングで開放制御することで、上記誘導車輪２２と同様の洗浄作業を左右の前輪２３と後輪２４のそれぞれに対しても実施することができる。具体的には、進行速度Ｖで移動する１つの車輪が３つの噴出ノズルの配置領域長さφＤπを通過するのに必要な時間がＤπ／Ｖであり、この間に当該３つの噴出ノズルを順に連携噴出させる電磁バルブＣ１～Ｃ３，Ｓ１～Ｓ３の開放制御を１セット行うことで当該１車輪に対する洗浄作業が可能となる。 In addition, the control panel 44 controls the other electromagnetic valves S1, S2, and S3 to open at an appropriate timing based on the detection timing X of the photoelectric sensor 35 as shown in the control time chart of FIG. The cleaning operation similar to that for the guide wheels 22 can be performed on the left and right front wheels 23 and the rear wheels 24, respectively. Specifically, the time required for one wheel moving at the traveling speed V to pass through the arrangement region length φDπ of the three ejection nozzles is Dπ/V, and the three ejection nozzles are linked in order during this time. By performing one set of opening control of the electromagnetic valves C1 to C3 and S1 to S3 for jetting, cleaning work for the one wheel can be performed.

このため、左列と右列で対応する対の噴出ノズル３２，３４を同時に噴出させる３つの電磁バルブＳ１，Ｓ２，Ｓ３の連携開放制御のセットを、光電センサ３５の検知タイミングＸから遅延時間Ｌ２／Ｖの経過後のタイミングＹと、同じ検知タイミングＸから遅延時間Ｌ３／Ｖの経過後のタイミングＺのそれぞれで実行開始すればよい。なお、このような各電磁バルブＣ１～Ｃ３，Ｓ１～Ｓ３のタイミング制御における遅延タイマー機能ついては、本実施形態の例では全て制御盤４４のコンピュータによって実現する。また、上記の３つのタイミングＸ，Ｙ，Ｚがそれぞれ噴出開始時期の一例である。 For this reason, a set of coordinated opening control of the three electromagnetic valves S1, S2, and S3 for simultaneously ejecting corresponding pairs of ejection nozzles 32 and 34 in the left and right columns is set from the detection timing X of the photoelectric sensor 35 to the delay time L2. /V, and at timing Z after a delay time L3/V from the same detection timing X. The delay timer function in the timing control of each of the electromagnetic valves C1 to C3 and S1 to S3 is realized entirely by the computer of the control panel 44 in the example of this embodiment. Also, the above three timings X, Y, and Z are examples of ejection start timings.

また以上から、洗浄作業部３全体の前後方向の長さ寸法Ｌｓは、一列分の３つの噴出ノズルの配置領域長さ（＝車輪の外周長さと同じ距離＝Ｄπ）より少しマージンを加えた長さ程度で設定すれば十分であり、配膳車２の誘導車輪２２から後輪２４までの長さ（Ｌ２＋Ｌ３）よりも短くできる。 In addition, from the above, the length Ls in the front-rear direction of the entire cleaning work unit 3 is the length of the arrangement area of the three ejection nozzles in one row (=the same distance as the outer circumference of the wheel=Dπ) plus a little margin. It suffices if the distance is set to a degree, and it can be made shorter than the length (L2+L3) from the guide wheel 22 to the rear wheel 24 of the catering cart 2.

＜実施形態の効果＞
以上説明したように、本実施形態においては、外部区画と衛生区画との間で運行される配膳車２の車輪２２，２３，２４の消毒を行う車輪消毒装置１であって、洗浄液供給部４５と、洗浄作業部３と、洗浄作業部３に備えられた光電センサ３５と、制御盤４４と有している。そしてこのうちの制御盤４４が、消毒エリア内において配膳車２とともに移動しかつ回転している車輪２２，２３，２４に対して洗浄液の噴出を行うように洗浄作業部３を制御する。 <Effects of Embodiment>
As described above, in the present embodiment, the wheel disinfection device 1 disinfects the wheels 22, 23, and 24 of the catering cart 2 operated between the external section and the sanitary section. , a cleaning unit 3 , a photoelectric sensor 35 provided in the cleaning unit 3 , and a control panel 44 . The control panel 44 controls the cleaning unit 3 so that the cleaning liquid is sprayed onto the wheels 22, 23, 24 that move and rotate together with the food cart 2 in the disinfection area.

これにより、作業者Ｍは配膳車２を洗浄作業部３上の適切な進路で進行させるだけで、車輪消毒装置１に自動的に車輪２２，２３，２４の消毒洗浄作業を行わせることができる。つまり、配膳車２を所定位置に一旦停止させる作業や、洗浄液の噴出と停止のための所定の手順の操作作業を不要として、車輪２２，２３，２４の消毒洗浄作業の自動化をさらに向上できる。 As a result, the worker M can cause the wheel sterilizer 1 to automatically perform the sterilization and cleaning work for the wheels 22, 23, and 24 only by advancing the catering cart 2 along an appropriate course on the cleaning work section 3. . In other words, it is possible to further improve the automation of the cleaning and disinfection of the wheels 22, 23 and 24 by eliminating the need for the work of temporarily stopping the catering cart 2 at a predetermined position and the operation of a predetermined procedure for spraying and stopping the cleaning liquid.

また、本実施形態では特に、制御盤４４が、その遅延タイマー機能により、光電センサ３５による配膳車２の通過の検知後、所定の遅延時間が経過したタイミングを洗浄液の噴出開始時期とするように洗浄作業部３を制御する。これにより、各車輪２２，２３，２４がそれぞれ対応する噴出ノズル３２，３３，３４の上方を通過する適宜のタイミングで、当該車輪２２，２３，２４の消毒洗浄に必要な噴出量だけで洗浄液を噴出させることができるため、洗浄液の消費を適切に抑制できる。 Moreover, in this embodiment, the control panel 44 uses its delay timer function to set the timing at which a predetermined delay time has elapsed after the photoelectric sensor 35 detects the passage of the catering cart 2 as the jetting start timing of the cleaning liquid. It controls the cleaning work section 3 . As a result, at appropriate timings when the wheels 22, 23, and 24 pass above the corresponding jet nozzles 32, 33, and 34, the cleaning liquid is sprayed in an amount necessary for disinfecting and cleaning the wheels 22, 23, and 24. Since the cleaning liquid can be jetted out, consumption of the cleaning liquid can be appropriately suppressed.

なお、各電磁バルブＣ１～Ｃ３，Ｓ１～Ｓ３のタイミング制御における遅延タイマー機能ついては、制御盤４４のコンピュータ以外にも、特に図示しない専用の電子回路や流体回路などを組み合わせて実現してもよい。また、配膳車２の通過を検知する手段としては、上記のように配膳車２側に光源としての検出用ＬＥＤ２６と、洗浄作業部３側に光検知側としての光電センサ３５を備える組み合わせに限られない。例えば、特に図示しないが、洗浄作業部３側に光源と光検知の両方を備えた投光反射検知型のものであったり、エコーなどの音波検知型のものであったり、ＲＦＩＤやＮＦＣを利用した電波検知型ものなど多様な手段を用いてもよい。またそのような検知センサの設置位置は洗浄作業部３の消毒エリア内に限られず、それよりも後方側の位置に設置してもよい。その場合には、誘導車輪２２の洗浄制御セットの開始タイミングについても、その検知センサの設置位置に応じた遅延時間で制御すればよい。 The delay timer function in the timing control of the electromagnetic valves C1-C3 and S1-S3 may be realized by combining a dedicated electronic circuit or fluid circuit (not shown) in addition to the computer of the control panel 44. Further, the means for detecting the passage of the food delivery cart 2 is limited to the combination of the detection LED 26 as the light source on the food delivery cart 2 side and the photoelectric sensor 35 as the light detection side on the cleaning work section 3 side as described above. can't For example, although not shown in particular, a light reflection detection type having both a light source and light detection on the cleaning operation unit 3 side, a sound wave detection type such as an echo, or RFID or NFC is used. Various means such as a radio wave detection type may be used. Moreover, the installation position of such a detection sensor is not limited to the inside of the disinfection area of the cleaning unit 3, and may be installed at a position on the rear side of the disinfection area. In that case, the start timing of the cleaning control set for the guide wheels 22 may also be controlled with a delay time corresponding to the installation position of the detection sensor.

また、本実施形態では特に、洗浄作業部３全体の前後方向に沿った長さ寸法は、配膳車２の進行方向最前方側の誘導車輪２２と進行方向最後方側の後輪２４との間の距離（Ｌ２＋Ｌ３）よりも小さく設定されている。これにより、配膳車２を一旦停止した状態で全ての車輪２２，２３，２４を同時に洗浄する場合（後述の図６参照）よりも、消毒エリアにおける洗浄作業部３の進行方向の設置長さを短縮化した省スペース化が可能となる。 In addition, particularly in this embodiment, the length dimension along the front-rear direction of the entire cleaning work unit 3 is the distance between the guide wheel 22 on the frontmost side in the traveling direction of the catering cart 2 and the rear wheel 24 on the rearmost side in the traveling direction. is set smaller than the distance (L2+L3) of . As a result, compared to the case where all the wheels 22, 23, and 24 are washed at the same time while the catering cart 2 is temporarily stopped (see FIG. 6, which will be described later), the installation length of the cleaning unit 3 in the direction of movement in the disinfection area is reduced. Shortened space saving is possible.

＜変形例＞
なお、本発明は、上記実施形態に限られるものではなく、その趣旨及び技術的思想を逸脱しない範囲内で種々の変形が可能である。そのような変形例を順を追って説明する。上記実施形態と同等の部分には同一の符号を付し、適宜、説明を省略又は簡略化する。 <Modification>
It should be noted that the present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the gist and technical idea of the present invention. Such modifications will be described in order. The same reference numerals are given to parts equivalent to those of the above-described embodiment, and description thereof will be omitted or simplified as appropriate.

＜全ての車輪を同時に洗浄する場合＞
上記実施形態では、配膳車２の誘導車輪２２、前輪２３、及び後輪２４をそれぞれ異なるタイミングで洗浄していたが、これに限られない。他にも図６に示すように、洗浄作業部３において、検出用ＬＥＤ２６（光電センサ３５）の位置を基準とした誘導車輪２２、前輪２３、及び後輪２４の各車輪にそれぞれに対応する全ての位置に噴出ノズルの列３２，３３，３４を設けた構成としてもよい。これにより光電センサ３５の検知タイミングＸで一斉に全ての車輪２２，２３，２４の洗浄作業を開始できるため、制御盤４４において各車輪２２，２３，２４別の噴出タイミング制御を行うための遅延タイマー機能が不要となり、制御構成を簡易にできる。 <When washing all wheels at the same time>
In the above-described embodiment, the guide wheels 22, the front wheels 23, and the rear wheels 24 of the catering cart 2 are washed at different timings, but the present invention is not limited to this. In addition, as shown in FIG. 6, in the cleaning work unit 3, all the guide wheels 22, the front wheels 23, and the rear wheels 24, which are based on the positions of the detection LEDs 26 (photoelectric sensors 35), are connected to the respective wheels. It is also possible to adopt a configuration in which the jet nozzle rows 32, 33, and 34 are provided at positions of . As a result, the washing operation of all the wheels 22, 23, 24 can be started all at once at the detection timing X of the photoelectric sensor 35. Therefore, a delay timer for performing ejection timing control for each wheel 22, 23, 24 in the control panel 44 is provided. This eliminates the need for functions and simplifies the control configuration.

＜各車輪ごとの洗浄開始タイミング検知用のセンサを設ける場合＞
上記実施形態では、１つの光電センサ３５による検知タイミングＸだけを基準として前輪２３と後輪２４それぞれの洗浄制御セットの開始タイミングＹ，Ｚを遅延制御していたが、これに限られない。他にも図７に示すように距離Ｌ２と距離Ｌ３で前方に離間した第２、第３の光電センサ３５Ａ，３５Ｂを設けることで、それぞれの検知タイミングをそのまま前輪２３と後輪２４の洗浄制御セットの開始タイミングＹ，Ｚとして同期させることができる。これにより制御盤４４において各車輪２２，２３，２４別の噴出タイミング制御を行うための遅延タイマー機能が不要となる他にも、作業者Ｍの牽引速度にムラがあっても正確な同期が可能となる。 <When providing a sensor for detecting the cleaning start timing for each wheel>
In the above embodiment, the start timings Y and Z of the cleaning control sets for the front wheels 23 and the rear wheels 24 are delayed based on only the detection timing X by the single photoelectric sensor 35, but the present invention is not limited to this. In addition, as shown in FIG. 7, by providing the second and third photoelectric sensors 35A and 35B spaced forward by a distance L2 and a distance L3, the cleaning control of the front wheel 23 and the rear wheel 24 can be performed without changing the respective detection timings. The set start timings Y and Z can be synchronized. This eliminates the need for a delay timer function for controlling the ejection timing of each wheel 22, 23, 24 in the control panel 44, and enables accurate synchronization even if the towing speed of the worker M is uneven. becomes.

＜各噴出ノズルの配置位置が調整可能な場合＞
上記実施形態では、洗浄作業部３内における各噴出ノズル３２，３３，３４の配置位置が固定されていたが、これに限られない。他にも図８に示すように、同列にある各噴出ノズル３３ｆ，３３ｍ，３３ｂが同じブラケット６上でそれぞれ前後方向の位置調整できるようスライド変更可能に設けられてもよい。また特に図示しないが、前輪２３と後輪２４においては左右方向での位置調整も可能となるよう設けてもよい。これにより、配膳車２における前後方向の車輪間隔Ｌ２、Ｌ３や左右方向の車輪間隔Ｗの仕様に合わせて適切な洗浄液の噴出位置を調整できる。 <When the arrangement position of each ejection nozzle is adjustable>
In the above-described embodiment, the arrangement positions of the jet nozzles 32, 33, and 34 in the cleaning work section 3 are fixed, but the present invention is not limited to this. Alternatively, as shown in FIG. 8, the jet nozzles 33f, 33m, and 33b in the same row may be provided on the same bracket 6 so as to be slidably changeable so that their positions can be adjusted in the front-rear direction. Also, although not shown, the front wheels 23 and the rear wheels 24 may be provided so that their positions can be adjusted in the left-right direction. As a result, it is possible to appropriately adjust the ejection position of the cleaning liquid according to the specifications of the wheel intervals L2 and L3 in the front-rear direction and the wheel interval W in the left-right direction of the catering cart 2 .

＜洗浄作業部を床面設置型とする場合＞
上記実施形態では、図９（ａ）に示すように洗浄作業部３を床面埋め込み型としていたが、これに限られない。他にも、図９（ｂ）に示すように、洗浄作業部３Ａ全体を略直方体形状の箱体で形成し、床面Ｆ上に設置するようにしてもよい。この場合には、配膳車２が洗浄作業部３上を通過しやすいように、当該洗浄作業部３の前後に適宜の傾斜角度を有するスロープ部７を設けるとよい。これにより、洗浄作業部３の移動と設置が簡易となり、増設、削減、配置変更、配置調整などが容易に行える。 <When the cleaning unit is installed on the floor>
In the above-described embodiment, as shown in FIG. 9A, the cleaning unit 3 is of the floor-embedded type, but is not limited to this. Alternatively, as shown in FIG. 9(b), the entire cleaning section 3A may be formed in a substantially rectangular parallelepiped box body and installed on the floor surface F. As shown in FIG. In this case, it is preferable to provide a slope portion 7 having an appropriate inclination angle in front and rear of the cleaning work section 3 so that the catering cart 2 can easily pass over the cleaning work section 3 . As a result, the movement and installation of the cleaning unit 3 are simplified, and addition, reduction, layout change, and layout adjustment can be easily performed.

＜洗浄液の噴出量、噴出時間、薬剤の種類を可変にする場合＞
上記実施形態では、洗浄液の噴出量、噴出時間、薬剤の種類を固定としていたが、これに限られない。他にも、図１０に示す噴出制御部４Ａのように、貯留する薬剤の種類が異なる２つの洗浄液タンク４１Ａ，４１Ｂを備え、制御盤４４からの制御によって切替バルブ４６がいずれの薬剤を混合バルブ４３へ供給するかを切り替え可能としてもよい。なお切替バルブ４６に変えて特に図示しない希釈バルブを備え、一方の薬剤を水又はアルコールとして希釈バルブによって他方の薬剤へ混合しその希釈濃度を調整してもよい。また、コンプレッサー４２の加圧力を制御するなどにより洗浄液の噴出量を可変に制御したり、また電磁バルブＣ１～Ｃ３，Ｓ１～Ｓ３の開放時間を制御するなどにより個々の噴出ノズル３２，３３，３４における洗浄液の噴出時間を可変に制御してもよい。これにより、その時点の配膳車２の状況や環境条件等に応じた洗浄作業の内容の調整が可能となる。 <In the case of varying the jetting amount, jetting time, and chemical type of the cleaning liquid>
In the above embodiment, the ejection amount, ejection time, and chemical type of the cleaning liquid are fixed, but the present invention is not limited to this. In addition, as in the ejection control unit 4A shown in FIG. 10, two cleaning liquid tanks 41A and 41B with different types of stored chemicals are provided, and a switching valve 46 is controlled by the control panel 44 to select which chemical to mix. 43 may be switchable. A dilution valve (not shown) may be provided instead of the switching valve 46, and one of the chemicals may be water or alcohol mixed with the other chemical by the dilution valve to adjust the dilution concentration. In addition, by controlling the pressurizing force of the compressor 42, the spray amount of the cleaning liquid is variably controlled, and by controlling the opening times of the electromagnetic valves C1 to C3 and S1 to S3, the individual spray nozzles 32, 33, and 34 are controlled. may be variably controlled. As a result, it becomes possible to adjust the contents of the cleaning work according to the situation of the catering cart 2 at that time, the environmental conditions, and the like.

具体的には、例えば生ものが多い献立が気温の高い昼食時に配膳された日に、たまたま長時間たってから下膳することになった場合は腐敗している可能性が高く、より適切な薬剤で、より念入りな洗浄が必要な場合がある。一方で、そのような特に重大な要因がない場合はできるだけ簡易に洗浄を済ませたい。このように各種の条件に応じて洗浄液の噴出量、噴出時間、薬剤の種類を可変に制御することは有用である。 Specifically, for example, on a day when a menu with many raw items is served at lunchtime when the temperature is high, if it happens to be served after a long time, there is a high possibility that it is spoiled, and a more appropriate chemical is used. and may require more thorough cleaning. On the other hand, if there are no such particularly serious factors, we would like to finish cleaning as simply as possible. Thus, it is useful to variably control the ejection amount, ejection time, and chemical type of the cleaning liquid according to various conditions.

これに対して、特に図示しないが、例えば配膳車２に無線タグＩＣを設けたり、ＱＲコード（登録商標）などの画像コードを印刷又は表示するなどのように記録媒体による所定情報の記録を行い、洗浄作業場の付近で対応する無線通信や光学的手段を介した読取装置によりそれら情報を読み取らせる。そして制御盤４４がその読み取った情報内容に基づいて洗浄液の噴出量、噴出時間、薬剤の種類を可変に制御すればよい。これにより、その時点の配膳車２の状況や時間帯などの環境条件等に応じた適切な内容の洗浄作業を実施することが可能となる。 In response to this, although not shown, predetermined information is recorded on a recording medium, such as by providing a wireless tag IC in the catering cart 2, or by printing or displaying an image code such as a QR code (registered trademark). , the information is read by a reader via corresponding wireless communication or optical means in the vicinity of the cleaning station. Then, the control panel 44 can variably control the jetting amount of the cleaning liquid, the jetting time, and the type of chemical based on the contents of the read information. As a result, it becomes possible to carry out the cleaning work with appropriate contents according to the situation of the catering cart 2 at that time and the environmental conditions such as the time of day.

＜配膳車自体が車輪の洗浄作業を行う参考例＞
なお、参考例として、図１１に示すように、配膳車２Ａ自体に噴出制御部４及び洗浄作業部３を設けて当該配膳車２Ａの車輪２２，２３，２４を洗浄させる構成も考えられる。この場合には、洗浄液を各車輪２２，２３，２４に向けて噴出可能な適宜の配置に噴出ノズル３２，３３，３４を設け、適切に接続された配管と電磁バルブ（図示省略）を介して制御盤４４が噴出制御を行う。 <Reference example in which the catering truck itself cleans the wheels>
As a reference example, as shown in FIG. 11, it is conceivable to provide a jet control unit 4 and a cleaning unit 3 in the catering cart 2A itself to clean the wheels 22, 23 and 24 of the catering cart 2A. In this case, jet nozzles 32, 33, and 34 are provided at appropriate positions that can jet the cleaning liquid toward each wheel 22, 23, and 24, and through appropriately connected pipes and electromagnetic valves (not shown), A control panel 44 performs ejection control.

またこの場合、図１２に示すように、各噴出ノズル３２，３３，３４か噴出させて車輪２２，２３，２４を洗浄した後の廃液を受けて回収するための廃液流し場８を、外部区画と衛生区画の間の消毒エリアとして特に図示しないグレーチングとともに床面Ｆに設けることが好ましい。なお、この廃液流し場８の前後方向長さ寸法を図示するようにＤπ程度に設定する場合には、廃液が外部に流れ出ないように各噴出ノズル３２，３３，３４の噴出タイミングの同期を図る必要がある。その場合には、廃液流し場８側の適宜の位置に検出用ＬＥＤ２６を設け、配膳車２側に光電センサ３５を設けて、配膳車２の制御盤４４に当該配膳車２の廃液流し場８への到着タイミングを検知させることもできる。これにより、配膳車２自体に車両洗浄に必要な構成のほとんどを備えさせることができ、外部環境設備への負担を大きく軽減できる。 In this case, as shown in FIG. 12, a waste liquid sink field 8 for receiving and recovering the waste liquid after washing the wheels 22, 23 and 24 by jetting from the jet nozzles 32, 33 and 34 is provided in the external compartment. It is preferable to provide the floor surface F together with a grating (not shown) as a disinfection area between the sanitary compartment and the sanitary compartment. When the length of the waste liquid flow field 8 in the longitudinal direction is set to about Dπ as shown in the figure, the jetting timings of the jetting nozzles 32, 33, and 34 are synchronized so that the waste liquid does not flow out to the outside. There is a need. In that case, a detection LED 26 is provided at an appropriate position on the side of the waste liquid flow field 8, a photoelectric sensor 35 is provided on the side of the food service car 2, and the waste liquid flow field 8 of the food service car 2 is connected to the control panel 44 of the food service car 2. It is also possible to detect the timing of arrival at As a result, the catering cart 2 itself can be provided with most of the components necessary for washing the vehicle, and the burden on the external environmental equipment can be greatly reduced.

なお、車輪消毒装置１が洗浄消毒する対象の車両、もしくは上記のように車輪を自ら洗浄消毒する車両自体は、食事を配膳、下膳する配膳車２に限られない。他にも、外部区画から衛生区画へ進入するために車輪２２，２３，２４を洗浄消毒する必要のある種類の車両に適用してもよい。 The vehicle to be cleaned and disinfected by the wheel disinfection device 1 or the vehicle itself whose wheels are cleaned and disinfected as described above is not limited to the catering cart 2 for serving and delivering meals.
