Description

本発明は、既設の給水装置を、その一部を残して改装することで構成した節水用給水装置に関するものである。   The present invention relates to a water-saving water supply device configured by refurbishing an existing water supply device while leaving a part thereof.

従来から業務用厨房で食器を洗うために給水するに当たって、節水するための節水装置が特許文献１により知られている。   Conventionally, Patent Document 1 discloses a water-saving device for saving water when water is supplied to wash dishes in a commercial kitchen.

この特許文献１に示された従来例は、水道菅に取付けられた電磁弁と、業務用厨房の洗い場の天井などに取付けられて洗い場の床に向けて赤外線を照射する赤外線センサと、電磁弁を開閉するためのスタート／ストップ釦と、貯水釦と、赤外線センサによる洗い場に人が居ることの検知と、スタート／ストップ釦や、貯水釦の操作に基づいて電磁弁の開閉制御を行うための制御部とを備えたものである。   The conventional example shown in Patent Document 1 includes an electromagnetic valve attached to a water tap, an infrared sensor that is attached to a ceiling of a washing place of a commercial kitchen and emits infrared rays toward the floor of the washing place, and an electromagnetic valve. Start / stop button for opening and closing, water storage button, infrared sensor to detect that there is a person in the washing area, and to perform opening / closing control of solenoid valve based on operation of start / stop button and water storage button And a control unit.

そして、赤外線センサで洗い場に人がいることを検知した状態で、スタート／ストップ釦を押すと電磁弁を開いて給水を開始し、スタート／ストップ釦を再度押すと電磁弁を閉じて給水を停止するもので、上記給水中に洗い場から人が去って人を検知しないと電磁弁を閉じて給水を停止するようになっている。   Then, with the infrared sensor detecting that there is a person in the washing area, pressing the start / stop button opens the solenoid valve to start water supply, and pressing the start / stop button again closes the solenoid valve to stop water supply. Therefore, if a person leaves the washing place during the water supply and does not detect the person, the solenoid valve is closed to stop the water supply.

また、赤外線センサで洗い場に人がいることを検知した状態で、貯水釦を押すと電磁弁を開いて所定時間給水し、所定時間が経過すると電磁弁を閉じて給水を停止する。この間、上記給水中に洗い場から人が去って人を検知しなくても、所定時間経過するまでは給水を継続し、所定時間経過すると電磁弁を閉じて給水を停止するようになっている。   In addition, when the infrared sensor detects that a person is in the washing area, when the water storage button is pressed, the electromagnetic valve is opened to supply water for a predetermined time, and when the predetermined time has elapsed, the electromagnetic valve is closed to stop water supply. During this time, even if the person leaves the washing place during the water supply and does not detect the person, the water supply continues until a predetermined time elapses, and when the predetermined time elapses, the electromagnetic valve is closed to stop the water supply.

上記の従来例にあっては、赤外線センサで洗い場に人がいることを検知した状態で、スタート／ストップ釦を押すと電磁弁を開いて給水を開始し、スタート／ストップ釦を再度押すと電磁弁を閉じて給水を停止するもので、上記給水中に洗い場から人が去って人を検知しないと電磁弁を閉じて給水を停止するものであるから、洗い場に立って（赤外線センサでその存在を検知された状態で）、スタート／ストップ釦を押した後は、食器の手洗い作業（前洗い作業）をしていない場合（例えば、洗い場に立ってはいるが食器の手洗い作業を具体的に開始していない時、あるいは、作業の途中で、食器の手洗いを一時的に中止した場合、あるいは、洗浄した食器を本洗浄装置に移送する作業をしている場合、あるいは、洗い場に立った姿勢で洗剤の補給をしている場合等）であっても、洗い場に立っている間は継続して給水が行われるようになっており、食器を手洗いする際の節水効果が十分であるとはいえない。   In the above conventional example, when the start / stop button is pressed with the infrared sensor detecting that there is a person in the washing area, the solenoid valve is opened to start water supply, and when the start / stop button is pressed again, the electromagnetic The water supply is stopped by closing the valve. If the person leaves the washing area during the water supply and does not detect the person, the electromagnetic valve is closed and the water supply is stopped. After the start / stop button is pressed, the tableware handwashing work (pre-washing work) is not performed (for example, the tabletop handwashing work is specifically performed while standing at the washing place) When it has not started, or when hand washing of dishes is temporarily stopped during the work, or when the work of transferring the washed dishes to the cleaning device is being performed, or at the washing place With detergent Even if, etc.) that the replenishment, while standing in washing place are adapted to the water supply is continued, water-saving effect when hand washing dishes can not be said to be sufficient.

また、ホテル、旅館、レストラン等の業務用の厨房における食器の手洗い作業においては、大別して中華料理、西洋料理、日本料理に使用した３種類の汚れた食器が発生する。ここで、上記３種類の汚れた食器のうち、一般的には中華料理に使用した食器や西洋料理に使用した食器は油分やソースが付着しているため、食器に付着した残滓を落とすのに手間がかかり、これに対して日本料理に使用した食器は中華料理や西洋料理に使用した食器に比べて残滓を落とすのが簡単である。   In addition, in the hand washing operation of tableware in commercial kitchens such as hotels, inns, restaurants, etc., three types of dirty tableware used for Chinese, Western, and Japanese dishes are generated. Here, among the above three types of dirty dishes, the dishes used for Chinese dishes and the dishes used for Western dishes are attached with oil and sauce, so it is necessary to remove the residue attached to the dishes. In contrast, the dishes used for Japanese cuisine are easier to remove than the dishes used for Chinese and Western dishes.

しかしながら、上記従来例にあっては、手洗いする食器が上記中華料理、西洋料理、日本料理のどれに使用したか、あるいは、汚れ状態に関係なく、スタート／ストップ釦を押して同じ水量の水を連続して供給して食器の手洗いをするものであるから、汚れ状態に応じた効果的な食器の洗浄ができず、特に、日本料理に使用した食器のように、中華料理や西洋料理に使用した食器に比べると油分、ソース等の付着が少なく、残滓が比較的取れ易いものの場合、食器の洗浄に当たって必要以上に水を使用することになり、この点でも節水が十分ではなかった。   However, in the above conventional example, regardless of whether the dishes to be hand-washed are used in the above Chinese dishes, Western dishes, or Japanese dishes, or whether the dishes are dirty, the start / stop button is pressed to continuously supply the same amount of water. Since the dishes are hand-washed, the dishes cannot be washed effectively according to the soiled condition, and especially used for Chinese and Western dishes like the dishes used in Japanese cuisine. Compared to tableware, if there is less adhesion of oil, sauce, etc., and the residue is relatively easy to remove, water will be used more than necessary to clean the tableware, and water saving was not sufficient in this respect as well.

また、一般に、上記のような節水装置を既設の業務用厨房に設置するには、既設の給水装置をすべて撤去して、既設の給水装置に代えて新規の節水装置付の給水装置を新たに設置するのが一般的であり、このため、コストが高くなるという問題があり、更に、上記従来例にあっては、これに加えて、水道工事とは別に、赤外線センサを洗い場の天井に取付ける作業をしなければならず、作業も煩雑となるという問題があった。
特開２００２−４７７０８号公報 In general, in order to install the above water-saving device in an existing commercial kitchen, all the existing water-supply devices are removed, and a new water-supply device with a water-saving device is newly replaced with the existing water-supply device. It is generally installed, and thus there is a problem that the cost becomes high. In addition, in the above-mentioned conventional example, in addition to this, an infrared sensor is attached to the ceiling of the washing place separately from the waterworks. There was a problem that work had to be done and the work was complicated.

A water-saving water supply device 6 constructed by refurbishment, comprising a new water supply connection rod 16 having a solenoid valve 14, a hot water supply new connection rod 18 having a solenoid valve 14, and a water supply port 12, Covered in a certain area of A new faucet rod 20 having a detection sensor 15 for detecting the presence of an intelligent object, a control unit 9 for opening and closing the electromagnetic valve 14 to control a plurality of water supply modes, and any of a plurality of water supply modes Forming a water-saving new water supply member set having mode setting means 21 for selecting and setting the water supply mode, and the presence of an object to be detected below the water supply port 12 as the plurality of water supply modes. When the detection sensor 15 detects the electromagnetic valve 14, the electromagnetic valve 14 is automatically opened to supply water from the water supply port 12, and when the detection sensor 15 does not detect the presence of an object to be detected below the water supply port 12, the electromagnetic valve 14 is turned on. A sensor automatic water supply / stop mode that automatically closes and stops water supply, and the electromagnetic valve 14 is opened to start water supply from the water supply port 12 and a predetermined time elapses, or water supply from the water supply port 12 is performed. For quantitative Then, the automatic water filling mode to the pre-washing sink 7 which automatically closes the electromagnetic valve 14 and stops water supply and the opening and closing of the electromagnetic valve 14 are intermittently performed alternately and intermittently from the water supply port 12. There are three water supply modes including an intermittent water supply mode for supplying water, and instead of the existing connection rod 43 for water supply and the existing connection rod 44 for hot water supply, the new connection rod 16 for water supply and the electromagnetic valve 14 provided with the electromagnetic valve 14 The existing hot water mixing device 19 is connected to the existing water supply pipe 41 and the existing hot water supply pipe 42 by using a new hot water supply connection rod 18 provided with the above. It is characterized by being connected to the existing hot and cold water mixing device 19.

このような構成とすることで、３つの給水モードのいずれかをモード設定手段２１で選択して設定することで、自動水張りモードを選択して設定した時は前洗い用シンク７への自動水張りができ、また、食器２の前洗いに当たって、中華料理や西洋料理に使用した食器２や汚れがひどい食器２の前洗いの場合は、センサ自動給・停止モードを選択して設定することで、給水口１２の下方に汚れた食器を位置さて前洗いをしている間中連続して給水して効果的に汚れのひどい食器２の前洗いができると共に、センサ自動給・停止モード中に、センサが給水口１２の下方に被検知物（食器２）を検知しない時、つまり、具体的に食器２の前洗い洗浄作業が行われていない時（例えば、前洗い作業を開始する前、あるいは、前洗い作業を一時中断したり、次の食器２の洗浄までに時間がある時）はセンサで被検知物（食器２）を検知しないので自動的に給水が停止されて、不必要に水を垂れ流しにすることがなく、また、日本料理に使用した食器２や汚れの程度が比較的少ない食器２の場合は、間欠給水モードに設定することで、前洗い用シンク７内に水張りした水で汚れを取り、間欠的に給水される水ですすぎをするといったように、少ない給水量で効果的に前洗いができ、これにより効果的に節水、省エネルギーを図ることができる。しかも、節水用給水装置６を構成するに当たって、給水用既設接続菅４３及び給湯用既設接続菅４４に代えて、電磁弁１４を備えた給水用新設接続菅１６及び電磁弁１４を備えた給湯用新設接続菅１８を用いて上記既設湯水混合装置１９を上記既設給水配管４１及び既設給湯配管４２に接続し、既設蛇口菅４５に代えて検知センサ１５付の新設蛇口菅２０を上記既設湯水混合装置１９に接続するだけで節水用給水装置６を構成でき、現場施工が簡単に行えるものであり、また、既設の給水装置５０の一部である既設湯水混合装置１９を残して節水用給水装置６を構成できるので、低コストで節水効果に優れた節水用給水装置６を提供できる。   By adopting such a configuration, any one of the three water supply modes is selected and set by the mode setting means 21. When the automatic water filling mode is selected and set, automatic water filling to the pre-washing sink 7 is performed. In addition, when pre-washing dishes 2 used in Chinese and Western dishes or pre-washing dishes 2 that are very dirty, select the sensor automatic feed / stop mode and set it. During the pre-washing with the dirty dishes positioned under the water supply port 12, the pre-washing of the very dirty dishes 2 can be carried out effectively throughout the pre-washing, and during the automatic sensor feed / stop mode, When the sensor does not detect an object to be detected (tableware 2) below the water supply port 12, that is, when the pre-cleaning operation of the tableware 2 is not specifically performed (for example, before starting the pre-cleaning operation, or Suspend pre-washing work When there is time until the next tableware 2 is washed), the sensor does not detect the object to be detected (tableware 2), so the water supply is automatically stopped, and water is not dripped unnecessarily. In addition, in the case of tableware 2 used for Japanese cuisine or tableware 2 with a relatively low level of dirt, by setting the intermittent water supply mode, dirt is removed with water filled in the pre-washing sink 7 and intermittently. Pre-washing can be done effectively with a small amount of water supply, such as rinsing with the water to be supplied, thereby effectively saving water and saving energy. Moreover, in configuring the water-saving water supply device 6, instead of the existing connection rod 43 for water supply and the existing connection rod 44 for hot water supply, the new connection rod 16 for water supply having the electromagnetic valve 14 and the hot water supply having the electromagnetic valve 14 are provided. The existing hot water mixing apparatus 19 is connected to the existing water supply pipe 41 and the existing hot water supply pipe 42 using a new connection rod 18, and the existing tap water mixer 20 with the detection sensor 15 is used instead of the existing tap water pipe 45.

この棒グラフ表示部３４に表示された設置前表示３１を見ることで、本発明の節水用給水装置６を設置する以前における食器２の前洗いのための一日における給水の一定時間（例えば１時間）毎の使用量の変化が一目で判ることになる。   By looking at the pre-installation display 31 displayed on the bar graph display unit 34, a predetermined time (for example, 1 hour) of water supply in the day for pre-washing the tableware 2 before installing the water-saving water supply device 6 of the present invention. ) You can see at a glance the change in usage.

目標値表示３２として表示される節水用給水装置６を設置することによる食器２の前洗いのための一日における給水の一定時間毎の使用量の変化の目標値は、上記のようにして求めた節水用給水装置６を設置する以前における食器２の前洗いのための一日における給水の一定時間毎の使用量の変化の実測値を基準にして求める。   The target value of the change in the amount of water used for a certain period of time in the day for pre-washing the tableware 2 by installing the water-saving water supply device 6 displayed as the target value display 32 is obtained as described above. Further, it is obtained on the basis of an actual measurement value of a change in the amount of water used every predetermined time for a day for pre-washing the tableware 2 before installing the water-saving water supply device 6.

つまり、業務用厨房において、本発明の節水用給水装置６を設置した場合と、設置しなかった場合との、給水の使用量の違いを実験により求めた結果、本発明の節水用給水装置６を設置した場合は、設置しない場合に比べて使用量が略５８％であったので、本実施形態においては、上記節水用給水装置６を設置する以前における食器２の前洗いのための一日における給水の一定時間毎の使用量の変化の実測値の５８％が目標値となり、これに基づき、表示処理部９ｆによりグラフ作成処理が行われて、図８のように一つの共通の棒グラフ表示部３４に一定時間（例えば１時間）毎の目標値表示３２が表示される。   In other words, in a commercial kitchen, the difference in the amount of water used between the case where the water-saving water supply device 6 of the present invention is installed and the case where it is not installed is obtained by experiments. As a result, the water-saving water supply device 6 of the present invention is obtained. In the present embodiment, the amount of water used for pre-washing the tableware 2 before installing the water-saving water supply device 6 is approximately 58% compared to the case where the water-saving water supply device 6 is not installed. 58% of the measured value of the change in the amount of water used every certain time in the water becomes the target value, and based on this, the graph processing is performed by the display processing unit 9f, and one common bar graph display as shown in FIG. A target value display 32 is displayed on the unit 34 at regular time intervals (for example, one hour).

この目標表示３２は、一つの共通の棒グラフ表示部３４に一定時間（例えば１時間）毎に表示された設置前表示３１に重ねて表示されるもので、実施形態では、一定時間（例えば１時間）毎に設置前表示３１の５８％の位置に太線として表示され、設置前表示３１の先端と、太線の目標表示３２の差がそれぞれ、一日の一定時間（例えば１時間）毎の節水目標量となる。これにより、例えば、節水用給水装置６を設置した当該業務用厨房における午前８時から午前９時までの１時間の節水目標量がどのくらいか、あるいは、午後６時から午後７までの１時間の節水目標量がどのくらいかといったことが一目で把握できる。   The target display 32 is displayed so as to be superimposed on the pre-installation display 31 displayed every fixed time (for example, 1 hour) on one common bar graph display unit 34. In the embodiment, the target display 32 is displayed for a fixed time (for example, 1 hour). ) Is displayed as a thick line at 58% of the pre-installation display 31 every time, and the difference between the tip of the pre-installation display 31 and the thick-line target display 32 is a water-saving target for each fixed time (for example, 1 hour) of the day. Amount. Thus, for example, what is the target water saving amount for 1 hour from 8 am to 9 am in the commercial kitchen where the water saving water supply device 6 is installed, or 1 hour from 6 pm to 7 pm It is possible to grasp at a glance how much water saving target amount is.

現在使用量表示３３に表示される節水用給水装置６を設置した状態での食器２の前洗いのための本日における給水の一定時間毎の使用量の変化の実測値は、電磁弁制御部９ａによる電磁弁１４（１４ａ、１４ｂ）の開時間と、電磁弁１４（１４ａ、１４ｂ）を開にした際の流量センサ１７で求めた瞬間流量に基づいて演算が行われて一定時間毎の実測値を求め、表示処理部９ｆによりグラフ作成処理が行われ、図８のように一つの共通の棒グラフ表示部３４に一定時間（例えば１時間）毎の現在使用量表示３３が表示される。   The actual value of the change in the amount of water used for a certain period of time for pre-washing the tableware 2 with the water-saving water supply device 6 displayed on the current usage amount display 33 installed is the solenoid valve controller 9a. The calculation is performed based on the opening time of the solenoid valve 14 (14a, 14b) by the flow rate and the instantaneous flow rate obtained by the flow sensor 17 when the solenoid valve 14 (14a, 14b) is opened, and the measured value at regular intervals. Then, a graph creation process is performed by the display processing unit 9f, and a current usage amount display 33 for every predetermined time (for example, one hour) is displayed on one common bar graph display unit 34 as shown in FIG.

この現在使用量表示３３は、一つの共通の棒グラフ表示部３４に一定時間（例えば１時間）毎に表示された設置前表示３１、目標値表示３２に重ねて棒グラフとして表示されるもので、一定時間（例えば１時間）毎に表示された設置前表示３１の先端と現在使用量表示３３の先端との差がそれぞれ、一日の一定時間（例えば１時間）毎の節水量となる。これにより、例えば、節水用給水装置６を設置した当該業務用厨房における午前８時から午前９時までの１時間の実際の節水量がどのくらいか、あるいは、午後６時から午後７までの１時間の実際の節水量がどのくらいかといったことが一目で把握できる。   The current usage amount display 33 is displayed as a bar graph superimposed on the pre-installation display 31 and the target value display 32 displayed every fixed time (for example, one hour) on one common bar graph display unit 34. The difference between the front end of the pre-installation display 31 displayed every time (for example, 1 hour) and the front end of the current usage amount display 33 is the amount of water saved every fixed time (for example, 1 hour) of the day. Thus, for example, what is the actual amount of water saved in one hour from 8:00 am to 9:00 am in the commercial kitchen where the water-saving water supply device 6 is installed, or one hour from 6:00 pm to 7 pm You can see at a glance how much water is actually saved.

また、一定時間（例えば１時間）毎に表示された目標値表示３２と現在使用量表示３３の先端とを見比べることで、現在使用している給水の使用量が目標とする使用量に対してどのくらい少ないかあるいはどのくらい多いかが一目で把握できるようになっている。   Further, by comparing the target value display 32 displayed every fixed time (for example, one hour) with the tip of the current usage amount display 33, the usage amount of the currently used water supply is compared with the target usage amount. You can see at a glance how much or how little.

次に、前述のようにして既設の給水装置５０の一部である既設湯水混合装置１９のみ残して新たに用意した節水用新設給水セットを用いて改装することで構成した本発明の節水用給水装置６を用いた業務用厨房における食器２の前洗い作業について説明する。   Next, the water-saving water supply of the present invention constructed by refurbishing using the newly prepared water-saving water supply set newly prepared while leaving only the existing hot water mixing device 19 which is a part of the existing water supply device 50 as described above. The pre-washing operation of the tableware 2 in the commercial kitchen using the apparatus 6 will be described.

本発明の節水用給水装置６を設置すると、初期設定用操作部２２を操作して当該節水用給水装置６を設置した業務用厨房の前洗い用シンク７に対する水張り水量の初期設定を行う。この場合、初期設定される水張り水量とは当該業務用厨房の前洗い用シンク７が満水となる水量のことであり、この水量は本発明の節水用給水装置６が設置される業務用厨房の前洗い用シンク７毎に異なる。   When the water-saving water supply device 6 of the present invention is installed, the initial setting operation unit 22 is operated to perform the initial setting of the amount of water filled in the pre-washing sink 7 of the commercial kitchen where the water-saving water supply device 6 is installed. In this case, the initially set amount of water filling is the amount of water in which the pre-washing sink 7 of the commercial kitchen is full, and this amount of water is that of the commercial kitchen where the water-saving water supply device 6 of the present invention is installed. Different for each pre-washing sink 7.

上記のようにして水張り水量の初期設定がなされた後、実際に使用されることになる。以下、その使用例を詳細に説明する。   After the initial setting of the amount of water filled as described above, it is actually used. Hereinafter, the usage example will be described in detail.

図９に示す実施形態の業務用厨房においては、当日の食器の前洗い作業を行うには、まず、作業者が操作パネル１１の電源スイッチ３０をオン操作をし、更に、自動水張りモード用の操作部２１ｂを操作して自動水張りモードに設定する。図１１には本発明の節水用給水装置６における自動水張りモードの制御フロー図が示してあり、この制御フロー図の流れにしたがって、電磁弁１４（１４ａ、１４ｂ）の開閉制御がなされて前洗い用シンク７に自動的に水張りがされる。   In the commercial kitchen of the embodiment shown in FIG. 9, in order to perform the pre-washing work of the tableware on the day, the operator first turns on the power switch 30 of the operation panel 11, and further, for the automatic water filling mode. The operation unit 21b is operated to set the automatic water filling mode. FIG. 11 shows a control flow chart of the automatic water filling mode in the water-saving water supply device 6 of the present invention. According to the flow of this control flow chart, the opening / closing control of the electromagnetic valves 14 (14a, 14b) is performed and the pre-washing is performed. The sink 7 is automatically filled with water.

ここで、添付図面に示す実施形態では、自動水張りモード用の操作部２１ｂが水張り量選択スイッチ２８を兼用しているので、自動水張りモード用の操作部２１ｂを１回又は２回又は３回押すことで、初期設定された水張り水量の１／３、又は、２／３、初期設定された水張り水量（満水）の何れかに設定する。これにより、電磁弁１４が自動的に開いて給水口１２から給水を開始して給水口１２からの給水が所定量（実施形態では電磁弁１４の開時間が所定時間）になると自動的に電磁弁１４（１４ａ、１４ｂ）を閉じて給水を停止し、前洗い用シンク７に水張りがなされる（前洗い用シンク７内に満水の１／３又は満水の２／３又は満水の水張りがされる）。   Here, in the embodiment shown in the attached drawings, since the operation unit 21b for the automatic water filling mode also serves as the water filling amount selection switch 28, the operation unit 21b for the automatic water filling mode is pushed once, twice or three times. Thus, it is set to either 1/3 or 2/3 of the initially set amount of water-filled water, or one of the initially set water-filled water amount (full water). As a result, when the solenoid valve 14 is automatically opened and water supply is started from the water supply port 12 and the water supply from the water supply port 12 reaches a predetermined amount (in the embodiment, the opening time of the electromagnetic valve 14 is a predetermined time), The valve 14 (14a, 14b) is closed to stop water supply, and the pre-washing sink 7 is filled with water (1/3 full water or 2/3 full water or full water is filled in the pre-washing sink 7). )

このように、前洗い用シンク７に水張りをして、食器２の前洗いの待機をする。次に、汚れた食器２が発生すると、汚れた食器２はいったん台５に置かれ、この台５に置かれた汚れた食器２を手洗いにより前洗いする。この場合、食器２の汚れ状態に応じて、センサ自動給・停止モード用の操作部２１ａ又は間欠給水モード用の操作部２１ｃのいずれかを操作して、センサ自動給・停止モード又は間欠給水モードのいずれかの給水モードに設定する。   In this manner, the pre-washing sink 7 is filled with water, and the tableware 2 is put on standby for pre-washing. Next, when the dirty tableware 2 is generated, the dirty tableware 2 is once placed on the table 5, and the dirty tableware 2 placed on the table 5 is pre-washed by hand washing. In this case, either the sensor automatic supply / stop mode operation unit 21a or the intermittent water supply mode operation unit 21c is operated according to the dirt state of the tableware 2, and the sensor automatic supply / stop mode or intermittent water supply mode is operated. Set to one of the water supply modes.

食器２が中華料理や西洋料理に使用して油分やソースの残滓が洗い流し難いものや汚れのひどいものの場合は、センサ自動給・停止モード用の操作部２１ａを操作してセンサ自動給・停止モードに設定する。図１２にはセンサ自動給・停止モードにおける制御フロー図が示してあり、この制御フロー図の流れにしたがって、電磁弁１４（１４ａ、１４ｂ）の開閉制御がなされ、給水口１２からの給水、給水停止がなされる。   If the tableware 2 is used for Chinese or Western dishes and the oil or sauce residue is difficult to wash away or is very dirty, the sensor automatic feed / stop mode operation unit 21a is operated to operate the sensor automatic feed / stop mode. Set to. FIG. 12 shows a control flow diagram in the sensor automatic supply / stop mode. According to the flow of this control flow diagram, the solenoid valve 14 (14a, 14b) is controlled to open and close, and water supply and water supply from the water supply port 12 are performed. A stop is made.

すなわち、センサ自動給・停止モードに設定すると、検知センサ１５により給水口１２の下方の一定の領域に被検知物（食器や作業者の手）を検知することで、検知センサ１５が食器や作業者の手を検知している間中自動的に電磁弁１４（１４ａ、１４ｂ）を開いて連続給水を行う。したがって、給水口１２の下方の一定領域において食器２の手洗い作業をしている間中給水が継続され、油分やソースの残滓やひどい汚れを確実に前洗いにより洗い流すことができる。   That is, when the sensor automatic supply / stop mode is set, the detection sensor 15 detects the object to be detected (tableware or an operator's hand) in a certain area below the water supply port 12, so that the detection sensor 15 detects the tableware or the work. During the detection of a person's hand, the solenoid valve 14 (14a, 14b) is automatically opened for continuous water supply. Accordingly, the water supply is continued while the tableware 2 is hand-washed in a certain area below the water supply port 12, so that oil, the residue of the sauce, and terrible dirt can be reliably washed away by pre-washing.

上記汚れのひどい食器２の前洗いに当たっては、食器２の全体又は一部を前洗い用シンク７内に張った水内に浸けたり、あるいは、食器２の全体を前洗い用シンク７内に張った水の水面上に出したりしながら給水口１２から供給する水により残滓を洗い流し、すすぎを行って前洗いを行うものである。   When pre-washing the above-mentioned dirty dishes 2, the whole or a part of the dishes 2 is soaked in water stretched in the pre-washing sink 7, or the whole tableware 2 is stretched in the pre-washing sink 7. The residue is washed away with water supplied from the water supply port 12 while being put out on the surface of the water, and rinsed to perform pre-washing.

センサ自動給・停止モードにおける運転中、食器２のすすぎが終わって検知センサ１５により給水口１２の下方の一定の領域に被検知物を検知しなくなると、つまり、給水口１２の下方の一定の領域に食器や作業者の手が存在しなくなると、自動的に電磁弁１４（１４ａ、１４ｂ）を閉じ、センサ自動給・停止モードにおいて一時的に給水が停止される。その後、検知センサ１５が給水口１２の下方の一定の領域に被検知物である食器や作業者の手を検知すると、再び、自動的に電磁弁１４（１４ａ、１４ｂ）を開いて検知センサ１５が食器や作業者の手を検知している間中自動的に電磁弁１４（１４ａ、１４ｂ）を開いて連続給水を行い、汚れのひどい食器２の前洗いを行うことになる。   During the operation in the sensor automatic supply / stop mode, when the tableware 2 has been rinsed and the detection sensor 15 no longer detects an object to be detected in a certain region below the water supply port 12, that is, a certain amount below the water supply port 12. When tableware or an operator's hand no longer exists in the area, the electromagnetic valve 14 (14a, 14b) is automatically closed, and water supply is temporarily stopped in the sensor automatic supply / stop mode. Thereafter, when the detection sensor 15 detects a tableware or an operator's hand, which is an object to be detected, in a certain area below the water inlet 12, the electromagnetic sensor 14 (14a, 14b) is automatically opened again to detect the detection sensor 15. However, while the tableware and the operator's hand are detected, the solenoid valve 14 (14a, 14b) is automatically opened to continuously supply water, and the tableware 2 having a high level of dirt is pre-washed.

このように、センサ自動給・停止モードにおいては、給水口１２の下方の一定領域において食器２の手洗い作業をしている間中給水が継続されるので、油分やソースの残滓やひどい汚れを確実に前洗いにより洗い流すことができると共に、センサ自動給・停止モードにおいて一時的に食器２の前洗いを中止している間は給水が停止されるので、センサ自動給・停止モードにおける給水の無駄がなくなって、節水することができる。   As described above, in the automatic sensor supply / stop mode, the water supply is continued during the hand washing operation of the tableware 2 in a certain area below the water supply port 12, so that oil and sauce residues and terrible dirt can be reliably ensured. In addition, since the water supply is stopped while the pre-washing of the tableware 2 is temporarily stopped in the sensor automatic supply / stop mode, the water supply is wasted in the sensor automatic supply / stop mode. Lost and can save water.

上記センサ自動給・停止モードを終了するには、センサ自動給・停止モード用の操作部２１ａをもう一度操作することでセンサ自動給・停止モードがオフになって該モードが終了する。   To end the sensor automatic feed / stop mode, the sensor automatic feed / stop mode is turned off by operating the sensor automatic feed / stop mode operation unit 21a once again, and the mode ends.

一方、食器２が日本料理に使用されたものや汚れが比較的少ないものの場合は、間欠給水モード用の操作部２１ｃを操作して間欠給水モードに設定する。図１３には間欠給水モードにおける制御フロー図が示してあり、この制御フロー図の流れにしたがって、電磁弁１４（１４ａ、１４ｂ）の開閉制御がなされ、給水口１２からの給水、給水停止がなされる。   On the other hand, if the tableware 2 is used for Japanese cuisine or has relatively little dirt, the operation unit 21c for the intermittent water supply mode is operated to set the intermittent water supply mode. FIG. 13 shows a control flow chart in the intermittent water supply mode. According to the flow of this control flow chart, the solenoid valve 14 (14a, 14b) is controlled to open and close, and water supply from the water supply port 12 is stopped. The

すなわち、間欠給水モードに設定すると、電磁弁１４（１４ａ、１４ｂ）の開と閉が交互に間欠的に行われて、給水口１２から間欠的に給水される。したがって、作業者は間欠的な給水を利用した食器２の手洗いと、前洗い用シンク７に張った水に漬けての食器２の手洗いとを併用しながら、食器２の手洗い作業を行って、最後にすすぎを行う。この場合、食器２の汚れが比較的少ないので、給水口１２からの給水を連続給水することなく間欠的に給水するものであっても、十分に前洗いを行うことができて、節水をすることができる。   That is, when the intermittent water supply mode is set, the electromagnetic valve 14 (14a, 14b) is alternately opened and closed alternately, and water is intermittently supplied from the water supply port 12. Therefore, the operator performs the hand-washing work of the tableware 2 while using both the hand-washing of the tableware 2 using intermittent water supply and the hand-washing of the tableware 2 soaked in the pre-sink 7 sink, Finally, rinse. In this case, since the tableware 2 is relatively dirty, even if the water supply from the water supply port 12 is intermittently supplied without continuously supplying water, it can be sufficiently pre-washed to save water. be able to.

上記間欠給水モード用の操作部２１ｃを終了するには、間欠給水モード用の操作部２１ｃをもう一度操作することで間欠給水モードをオフにして終了することができる。   To end the intermittent water supply mode operation unit 21c, the intermittent water supply mode can be turned off by operating the intermittent water supply mode operation unit 21c once more.

上記、食器２の前洗いにおけるセンサ自動給・停止モードの際の食器２の手洗い作業や間欠給水モードの際の食器の手洗い作業に当たって、洗剤を適宜使用して手洗いをする。使用する洗剤は作業者がその都度必要に応じて手作業で食器２や洗浄スポンジなどに付けて使用したり、あるいは、洗剤自動供給装置から自動的に供給して使用するようにする。   When washing the tableware 2 in the pre-washing sensor automatic feed / stop mode, the tableware 2 is washed in hand or in the intermittent water supply mode, and handwashing is performed using an appropriate detergent. The detergent to be used is used by the operator by manually attaching it to the tableware 2 or the cleaning sponge as needed, or automatically supplied from the detergent automatic supply device.

また、前洗い用シンク７に張った水が汚れてくると、必要に応じて前洗い用シンク７に設けた排水弁（図示せず）を開いて前洗い用シンク７内の汚れた水を排水し、排水後排水弁を閉じて、前述と同様にして自動水張りモード用の操作部２１ｂを操作して前洗い用シンク７に水張りを行い、その後、センサ自動給・停止モード又は間欠給水モードのいずれかを選択して食器２の手洗いによる前洗いを行う。   Further, when the water stretched on the pre-washing sink 7 becomes dirty, if necessary, the drain valve (not shown) provided in the pre-washing sink 7 is opened to remove the dirty water in the pre-washing sink 7. Drain, close the drain valve after draining, operate the automatic water filling mode operation part 21b in the same manner as described above to fill the pre-washing sink 7, and then use the sensor automatic supply / stop mode or intermittent water supply mode Is selected and the tableware 2 is pre-washed by hand washing.

上記のように、センサ自動給・停止モード又は間欠給水モードを選択して前洗い処理された食器は、食器本洗浄部４に送られて本洗浄される。この食器本洗浄部４においてはコンベアのような自動搬送手段により食器２を搬送しながら、洗剤を使った自動洗浄、自動すすぎを行う。   As described above, the tableware that has been prewashed by selecting the sensor automatic supply / stop mode or the intermittent water supply mode is sent to the tableware cleaning unit 4 for main cleaning. In the tableware cleaning unit 4, automatic cleaning using a detergent and automatic rinsing are performed while the tableware 2 is transferred by an automatic transfer means such as a conveyor.

ところで、本発明においては、上記のようにしてセンサ自動給・停止モード、間欠給水モードを選択して、給水口１２から給水しながら食器２の前洗い作業を行うのであるが、これら給水口１２からの実際に供給されている本日の給水量を一定時間毎（実施形態では１時間毎）表示画面１０に表示することに特徴がある。   By the way, in this invention, the sensor automatic feed / stop mode and the intermittent water supply mode are selected as described above, and the pre-washing operation of the tableware 2 is performed while water is supplied from the water supply port 12. It is characterized in that the water supply amount of today that is actually supplied from is displayed on the display screen 10 at regular intervals (in the embodiment, every hour).

すなわち、電源スイッチ３０をオン操作をすると、表示画面１０の棒グラフ表示部３４に設置前表示３１と、目標値表示３２がなされる。   That is, when the power switch 30 is turned on, a pre-installation display 31 and a target value display 32 are displayed on the bar graph display unit 34 of the display screen 10.

次に、前述のように給水モードを選択し、設定した給水モードに応じて電磁弁１４（１４ａ、１４ｂ）の開閉制御をして給水口１２から給水しながら食器２の前洗い作業をするのであるが、このときの電磁弁制御部９ａにより電磁弁１４（１４ａ、１４ｂ）の開閉を監視し、開にした際の瞬間流量に基づいて演算が行われて一定時間毎の実測値を求め、棒グラフ表示部３４に表示されている設置前表示３１、目標値表示３２に重ねて現在使用量表示３３が一定時間（例えば１時間）毎に表示される。この一定時間毎の表示に当たっては、例えば、電磁弁１４が１分開放する毎に現在の時間帯（例えば図８の例では１４時から１５時）に瞬時流量（例えば１０Ｌ／ｍｉｎ）分グラフが積み上がって表示される。   Next, since the water supply mode is selected as described above, the table 2 is pre-washed while supplying water from the water supply port 12 by controlling the opening and closing of the electromagnetic valves 14 (14a, 14b) according to the set water supply mode. However, the solenoid valve controller 9a at this time monitors the opening and closing of the solenoid valve 14 (14a, 14b), and the calculation is performed on the basis of the instantaneous flow rate when the solenoid valve 14 is opened, and the measured value is obtained every fixed time, A current usage amount display 33 is displayed every predetermined time (for example, one hour) so as to overlap the pre-installation display 31 and the target value display 32 displayed on the bar graph display unit 34. For the display at regular intervals, for example, every time the solenoid valve 14 is opened for 1 minute, a graph for instantaneous flow rate (for example, 10 L / min) is displayed in the current time zone (for example, 14:00 to 15:00 in the example of FIG. 8). Stacked and displayed.

この現在使用量表示３３は本日における電源スイッチ３０をオンにしてから現時点までの給水量が一定時間（例えば１時間）毎に表示されるので、本日における食器の前洗いに使用する一定時間毎の水の使用量が、設置前表示３１、目標値表示３２に対してどの程度の使用量であるかが、作業者が一目で把握でき、設置前表示３１と現在使用量表示３３との差により本発明の節水用給水装置６を設置したことによる節水量を把握できる。   The current usage amount display 33 displays the amount of water supply from the time when the power switch 30 is turned on to the present time every predetermined time (for example, 1 hour), so that the current usage amount display 33 is used for the daily pre-washing of the tableware. The operator can grasp at a glance how much the amount of water used is relative to the pre-installation display 31 and the target value display 32. The difference between the pre-installation display 31 and the current use display 33 It is possible to grasp the amount of water saved by installing the water-saving water supply device 6 of the present invention.

また、現在使用量表示３３が目標値表示３２を下回っていると、前洗い作業が効率よく行なわれて節水効果が上がっていることを作業者に強く意識させ、よりいっそう目標表示３２より下回るような効率のよい前洗い作業をしようとする強い意欲を作業者に与えることができる。   Further, when the current usage amount display 33 is below the target value display 32, the worker is strongly aware that the pre-washing operation is efficiently performed and the water-saving effect is increased, so that the worker is less than the target display 32. It is possible to give the worker a strong desire to perform efficient and efficient pre-cleaning work.

また、現在使用量表示３３が目標値表示３２を上回っていると、現在おこなっている前洗い作業のやり方に改善の余地があることを作業者に強く認識させ、食器２の汚れに応じて選択した給水モードの設定が適切であったか、あるいは、食器２を手洗いする際の作業手順や手洗いに要する時間が適切であったか、といった手洗い作業上の問題点を意識させるという効果がある。   Further, if the current usage amount display 33 exceeds the target value display 32, the worker is strongly aware that there is room for improvement in the manner of the pre-cleaning work currently being performed, and is selected according to the stains on the tableware 2. There is an effect of making the user aware of problems in hand-washing work, such as whether the setting of the water supply mode is appropriate, or whether the work procedure and time required for hand-washing the tableware 2 are appropriate.

一方、業務用厨房の管理者は、食器２の前洗い作業の一日における一定時間毎の水の使用量が適正であるか否か、あるいは、どの程度節水されているかということを知ることができ、水の使用量の管理を適切に行うことができる。   On the other hand, the manager of the commercial kitchen knows whether or not the amount of water used at regular intervals in the day of the pre-washing operation of the tableware 2 is appropriate or how much water is being saved. It is possible to manage the amount of water used appropriately.

このように、設置前表示３１、目標値表示３２、現在使用量表示３３の表示をする表示画面１０を設けることで、作業者、管理者の双方に対して、本発明の節水用給水装置６を設置したことによる節水効果をアピールすると共に、節水に対する強い動機付けを与え、食器の前洗い作業の効率化とコストダウンを図ることができる。また、給水モードを選択して選択した給水モードに基づいて自動的に給水するので、作業者が機器に触れて操作する回数を少なくし、衛生的である。   Thus, by providing the display screen 10 for displaying the pre-installation display 31, the target value display 32, and the current usage amount display 33, the water-saving water supply device 6 of the present invention is provided to both the operator and the administrator. In addition to appealing the water-saving effect of the installation, it can provide a strong motivation for water-saving, and can improve the efficiency and cost of pre-washing dishes. Moreover, since water supply is automatically performed based on the selected water supply mode by selecting the water supply mode, the number of times that the operator touches the device to operate is reduced, which is sanitary.

ところで、本発明においては、給水口１２から給水するに当たり、給水用新設接続菅１６から供給される水と、給湯用新設接続菅１８から供給される湯とが既設湯水混合装置１９で混合されて給水口１２から供給されるようになっている。   By the way, in the present invention, when water is supplied from the water supply port 12, the water supplied from the new water supply connection rod 16 and the hot water supplied from the hot water supply new connection rod 18 are mixed by the existing hot water mixing device 19. It is supplied from the water supply port 12.

既設湯水混合装置１９には水と湯との混合割合を手動で調整する湯温調整操作手段１９ｃが設けてあり、湯温調整操作手段１９ｃを調整することで、食器２の前洗いの際に給水口１２から供給する水（湯）の湯温を調整することができるようになっている。   The existing hot and cold water mixing device 19 is provided with a hot water temperature adjusting operation means 19c for manually adjusting the mixing ratio of water and hot water. By adjusting the hot water temperature adjusting operation means 19c, the tableware 2 is pre-washed. The temperature of the water (hot water) supplied from the water supply port 12 can be adjusted.

また、図１、図２に示す実施形態では、既設湯水混合装置１９に混合した混合水の給水量を手動で調整するための給水量調整操作手段１９ｄを設けてある。   Moreover, in embodiment shown in FIG. 1, FIG. 2, the water supply amount adjustment operation means 19d for adjusting manually the water supply amount of the mixed water mixed with the existing hot water mixing apparatus 19 is provided.

図１、図２に示す実施形態においては既設湯水混合装置１９に設けた一つの操作レバーが湯温調整操作手段１９ｃと給水量調整操作手段１９ｄを兼用しており、操作レバーを手に持って左右方向に回動することで水と湯との混合割合を変えて混合湯温の調整を行い、操作レバーを手に持って上下方向に回動することで湯量の調整、つまり、給水口１２からの単位時間当たりの給水量の調整を行うようにしている。もちろん、湯温調整操作手段１９ｃと給水量調整操作手段１９ｄとが別々の手動の操作部であってもよい。   In the embodiment shown in FIGS. 1 and 2, one operating lever provided in the existing hot water mixing device 19 serves as both the hot water temperature adjusting operation means 19c and the water supply amount adjusting operating means 19d, and holds the operating lever in hand. The mixed water temperature is adjusted by changing the mixing ratio of water and hot water by turning left and right, and the amount of hot water is adjusted by holding the operating lever in the hand and turning up and down, that is, the water inlet 12 The amount of water supply per unit time is adjusted. Of course, the hot water temperature adjustment operation means 19c and the water supply amount adjustment operation means 19d may be separate manual operation units.

この給水量調整操作手段１９ｄの調整は例えば以下のようにして行う。例えば、自動水張りモードにおいて前洗い用シンク７に水張りするに当たっては短時間で水張りする必要があるので、給水量調整操作手段１９ｄを操作して単位時間当たりの給水量を最大（例えば、２０Ｌ／ｍｉｎ）にして給水する。したがって、自動水張りモードにおける給水量の初期設定を、添付図面に示す実施形態のように、初期設定用操作部２２を操作して給水時間の設定を行うことで給水量の初期設定をする場合は、給水量調整操作手段１９ｄを操作して最大に開放して単位時間当たりの給水量を最大にした状態において給水口１２から連続給水して前洗い用シンク７を満水にするまでの給水時間を設定することになる。   The adjustment of the water supply amount adjusting operation means 19d is performed as follows, for example. For example, since it is necessary to fill the sink 7 for pre-washing in the automatic water filling mode in a short time, the water supply adjustment unit 19d is operated to maximize the water supply amount per unit time (for example, 20 L / min). ) To supply water. Therefore, when the initial setting of the water supply amount in the automatic water filling mode is performed by setting the water supply time by operating the initial setting operation unit 22 as in the embodiment shown in the accompanying drawings. The water supply time until the pre-washing sink 7 is fully filled by continuously supplying water from the water supply port 12 in a state where the water supply amount adjusting operation means 19d is operated and opened to the maximum to maximize the water supply amount per unit time. Will be set.

したがって、給水量調整操作手段１９ｄを設けた実施形態においては、自動水張りモード用の操作部２１ｂを操作して自動水張りモードに設定する際に、給水量調整操作手段１９ｄを操作して給水量を最大にし、この状態で前洗い用シンク７に自動的に水張りをするものである。これにより最短時間で前洗い用シンク７に目的とする水量の水張りができる。   Therefore, in the embodiment provided with the water supply amount adjusting operation means 19d, when the automatic water filling mode operation unit 21b is operated to set the automatic water filling mode, the water supply amount adjusting operation means 19d is operated to set the water supply amount. In this state, the pre-sink 7 is automatically filled with water. As a result, the pre-washing sink 7 can be filled with the desired amount of water in the shortest possible time.

一方、センサ自動給・停止モードや間欠給水モードの場合は、給水量調整操作手段１９ｄを操作して開放度を調整して、センサ自動給・停止モードや間欠給水モードにおける単位時間当たりの給水量を任意に調整する（例えば、約１０Ｌ／ｍｉｎ）。これにより、食器２の前洗いに当たっての単位時間当たりの最適の給水量で前洗いができて、よりいっそうの節水を図りながら作業性を向上することができる。   On the other hand, in the case of the sensor automatic water supply / stop mode or the intermittent water supply mode, the water supply amount adjustment operation means 19d is operated to adjust the degree of opening, and the water supply amount per unit time in the sensor automatic water supply / stop mode or the intermittent water supply mode. Is arbitrarily adjusted (for example, about 10 L / min). Thereby, pre-washing can be performed with an optimal water supply amount per unit time for pre-washing the tableware 2, and workability can be improved while further saving water.

そして、上記のような節水効果にすぐれた節水用給水装置６を構成するに当たって、本発明においては、給水用既設接続菅４３及び給湯用既設接続菅４４に代えて、電磁弁１４を備えた給水用新設接続菅１６及び電磁弁１４を備えた給湯用新設接続菅１８を用いて上記既設湯水混合装置１９を上記既設給水配管４１及び既設給湯配管４２に接続し、既設蛇口菅４５に代えて検知センサ１５付の新設蛇口菅２０を上記既設湯水混合装置１９に接続するだけで節水用給水装置６を構成でき、現場施工が簡単に行える。   In constructing the water-saving water supply device 6 having excellent water-saving effects as described above, in the present invention, water supply provided with the electromagnetic valve 14 in place of the existing connection rod 43 for water supply and the existing connection rod 44 for hot water supply. The existing hot water mixing device 19 is connected to the existing water supply pipe 41 and the existing hot water supply pipe 42 by using a new hot water supply connection rod 18 equipped with a new hot water connection rod 16 and a solenoid valve 14, and is detected in place of the existing faucet rod 45. The water-saving water supply device 6 can be configured simply by connecting the new faucet rod 20 with the sensor 15 to the existing hot and cold water mixing device 19, and the construction at the site can be performed easily.
