Description

液体提供装置及び液体提供装置用ノズルLiquid donor and nozzle for liquid donor
　本発明は、ドリンクバー等においてドリンクサーバ等として設置される液体提供装置及び液体提供装置用ノズルに関する。 The present invention relates to a liquid supply device and a nozzle for the liquid supply device installed as a drink server or the like in a drink bar or the like.
　ドリンクサーバでは、ノズルからの飲み物の放出終了後、少量の飲み物がノズル内に残存することがある。残存液は、次に飲み物が放出される時に次の飲み物に混ざって、ノズルから放出される。しかしながら、次の飲み物の放出時までの時間間隔が長いと、残存液内で菌が繁殖して、次の飲み物の品質が悪化する傾向が強まる。 In the drink server, a small amount of drink may remain in the nozzle after the discharge of the drink from the nozzle is completed. The residual liquid is mixed with the next drink and discharged from the nozzle the next time the drink is discharged. However, if the time interval until the release of the next drink is long, bacteria will propagate in the residual liquid, and the quality of the next drink will tend to deteriorate.
　特許文献１は、紫外光の光源がノズルの先端部に取り付けられ、該光源から紫外光をノズル内に放射して、殺菌を行う殺菌装置を開示する。該殺菌装置では、光源の電力の供給は、ノズルから外に配線を延ばし、外部の電源から配線を介して行われる。 Patent Document 1 discloses a sterilizer in which a light source of ultraviolet light is attached to a tip of a nozzle and radiates ultraviolet light into the nozzle from the light source to perform sterilization. In the sterilizer, the power supply of the light source is performed by extending the wiring from the nozzle to the outside and from the external power source via the wiring.
特開２０１８－６１６１８号公報JP-A-2018-61618
　特許文献１のように、ノズルの先端部の光源に外付けの配線を介して給電するときの問題点を列挙すると次のとおりである。 As in Patent Document 1, the problems when power is supplied to the light source at the tip of the nozzle via external wiring are as follows.
（ａ）外部配線がノズルに一体的に接続されているので、ノズルを交換する際は、配線をノズルから取り外す必要がある。しかしながら、ノズルからの配線の取り外し作業は、きわめて煩雑であり、実質上、ノズルの交換は無理となる。
（ｂ）ノズルと外部配線とを分離自在のコネクタで電気的に接続すると、コネクタが外部に露出し、漏電を防止するために電気コネクタに防水対策が必要になる。これは、コスト増につながる。
（ｃ）配線が外に露出しているので、見栄えが悪い。 (A) Since the external wiring is integrally connected to the nozzle, it is necessary to remove the wiring from the nozzle when replacing the nozzle. However, the work of removing the wiring from the nozzle is extremely complicated, and it is practically impossible to replace the nozzle.
(B) When the nozzle and the external wiring are electrically connected by a separable connector, the connector is exposed to the outside, and the electric connector needs to be waterproofed to prevent electric leakage. This leads to increased costs.
(C) Since the wiring is exposed to the outside, it looks bad.
　本発明は、上記問題点に鑑みてなされたもので、電気的なコネクタを用いることなくノズルの光源に給電可能で、かつノズルを容易に交換可能にする液体提供装置及び液体提供装置用ノズルを提供することを目的とする。 The present invention has been made in view of the above problems, and provides a liquid feeder and a nozzle for a liquid donor which can supply power to the light source of the nozzle without using an electric connector and can easily replace the nozzle. The purpose is to provide.

FIG. 3 is a vertical cross-sectional view of the nozzle 17. The nozzle 17 includes a cylindrical nozzle body 45 inside in the radial direction and a cover 46 that covers the outer peripheral portion of the nozzle body 45. The liquid receiving passage 38 extends into the nozzle body 45 along the central axis of the nozzle body 45 as a straight passage.
　ノズル本体４５は、少なくとも先端部（図３では、下端部）において紫外光を透過する材料（例：石英）からなる。１対の突起４９は、ノズル本体４５の基端部（図３では、上端部）の外周部に、相互に周方向に１８０°離れて形成されている。 The nozzle body 45 is made of a material (example: quartz) that transmits ultraviolet light at least at the tip (lower end in FIG. 3).

　（送電側構造）
　図４は、図３のノズル１７が着脱自在に装着される本体部１２側（ノズル用装着部３２）の構造図である。円形の挿通孔６６は、本体部１２の下壁６５においてノズル１７の上端部が挿入される箇所に形成され、下壁６５を貫通している。 (Power transmission side structure)
FIG. 4 is a structural diagram of the main body portion 12 side (nozzle mounting portion 32) to which the nozzle 17 of FIG. 3 is detachably mounted. The circular insertion hole 66 is formed in the lower wall 65 of the main body 12 at a position where the upper end of the nozzle 17 is inserted, and penetrates the lower wall 65.
　ノズル１７がノズル用装着部３２（図２）に装着されたときは、挿通孔６６の周辺部の下壁６５の部分は、フランジ部５３が接触する本体装置２９側の接触部分となる。なお、フランジ部５３と該接触部分との接触は、面接触である。 When the nozzle 17 is mounted on the nozzle mounting portion 32 (FIG. 2), the portion of the lower wall 65 of the peripheral portion of the insertion hole 66 becomes the contact portion on the main body device 29 side with which the flange portion 53 contacts. The contact between the flange portion 53 and the contact portion is a surface contact.
　環状溝６９は、挿通孔６６と同軸となるように、下壁６５の上面に開口して形成されている。送電用コイル７０は、受電用コイル５８の周回半径と同一の周回半径で挿通孔６６の中心軸の周りに周回するように、巻かれて、環状溝６９内に嵌挿されている。 The annular groove 69 is formed by opening on the upper surface of the lower wall 65 so as to be coaxial with the insertion hole 66. The power transmission coil 70 is wound around the central axis of the insertion hole 66 with the same circumference radius as that of the power reception coil 58, and is fitted in the annular groove 69.
　（ノズルの着脱）
　図５は、ノズル１７が本体部１２に取り付けられたときの模式図である。挿通孔６６の周縁には、周方向に１８０°離れた２箇所には、切欠き孔（図示せず）が形成されている。操作者は、周方向にノズル１７の上端部の各突起４９の位置を下壁６５の各切欠き孔の位置に合わせてからノズル１７を上方へ押し込む。これにより、突起４９は、切欠き孔を通過して、本体部１２のノズル用装着部３２（図２）の内周側に進入する。 (Detachment of nozzle)
FIG. 5 is a schematic view when the nozzle 17 is attached to the main body 12. Notches (not shown) are formed at two locations 180 ° apart in the circumferential direction on the peripheral edge of the insertion hole 66. The operator aligns the positions of the protrusions 49 at the upper end of the nozzle 17 with the positions of the notch holes in the lower wall 65 in the circumferential direction, and then pushes the nozzle 17 upward. As a result, the protrusion 49 passes through the notch hole and enters the inner peripheral side of the nozzle mounting portion 32 (FIG. 2) of the main body portion 12.
　次に、操作者は、ノズル１７を周方向に所定量回転させる。これにより、突起４９がノズル用装着部３２の内面の円周案内溝（図示せず）に沿って進み、ノズル用装着部３２の内面に係止されて、ノズル用装着部３２へのノズル１７の装着が完了する。ノズル用装着部３２からのノズル１７の離脱は、装着とは逆の手順で行う。 Next, the operator rotates the nozzle 17 in the circumferential direction by a predetermined amount. As a result, the protrusion 49 advances along the circumferential guide groove (not shown) on the inner surface of the nozzle mounting portion 32, is locked to the inner surface of the nozzle mounting portion 32, and the nozzle 17 to the nozzle mounting portion 32. Installation is completed. The nozzle 17 is detached from the nozzle mounting portion 32 in the reverse procedure of mounting.

　ポンプ駆動部７５がポンプ３３に駆動電流を供給している期間は、ノズル１７への飲み物１８の送出期間となる。ポンプ駆動部７５がポンプ３３に駆動電流の供給を停止している期間は、ノズル１７への飲み物１８の非送出期間となる。この結果、ポンプ駆動部７５は、本体装置２９からノズル１７への給液スイッチ１６の送出期間と非送出期間とを検出する送出検出部の機能を備える。 The period during which the pump drive unit 75 supplies the drive current to the pump 33 is the period during which the drink 18 is delivered to the nozzle 17. The period during which the pump drive unit 75 stops supplying the drive current to the pump 33 is a non-delivery period of the drink 18 to the nozzle 17. As a result, the pump drive unit 75 has a function of a transmission detection unit that detects a transmission period and a non-delivery period of the liquid supply switch 16 from the main body device 29 to the nozzle 17.
　給電切替部７７は、ワイヤレス給電部８０の送電用コイル７０に給電する給電期間と給電を中止する非給電期間とを切り替える。制御部７６は、送出期間は、全期間を非給電期間とし、また、非送出期間は、給電期間と前記非給電期間とを交互に繰り返すように、給電切替部７７を制御する。 The power supply switching unit 77 switches between a power supply period for supplying power to the power transmission coil 70 of the wireless power supply unit 80 and a non-power supply period for stopping power supply. The control unit 76 controls the power supply switching unit 77 so that the entire transmission period is a non-power supply period and the non-delivery period alternately repeats the power supply period and the non-power supply period.
　記憶部７８は、ノズル１７の受液通路３８の残液において繁殖する菌の世代交代の時間間隔に係るデータが書き込まれている。制御部７６は、非送出期間中の各非給電期間の長さを、記憶部７８から読み出した世代交代の時間間隔より短くなるように、給電切替部７７のオン、オフを制御する。 In the storage unit 78, data relating to the time interval of the generational change of the bacteria that propagate in the residual liquid of the liquid receiving passage 38 of the nozzle 17 is written. The control unit 76 controls the on / off of the power supply switching unit 77 so that the length of each non-power supply period during the non-delivery period is shorter than the time interval of the generation change read from the storage unit 78.
　ノズル１７において、受電用コイル５８は、ＬＥＤ３９に接続されている。受電用コイル５８及び送電用コイル７０は、ワイヤレス給電部８０を構成する。 In the nozzle 17, the power receiving coil 58 is connected to the LED 39. The power receiving coil 58 and the power transmission coil 70 form a wireless power feeding unit 80.

The AC distributor 84 distributes the AC from the AC power supply 83 to the AC-DC converter 85 and the AC switch 86.
　ＡＣ－ＤＣ変換器８５は、ＡＣ分配器８４からの交流を直流に変換する。交流スイッチ８６は、ＡＣ分配器８４と電気コネクタ８９との間に介在する。直流スイッチ８７は、ＡＣ－ＤＣ変換器８５と電気コネクタ８９との間に介在する。ＯＮ－ＯＦＦ制御器８８は、給液スイッチ１６からの信号に基づいて交流スイッチ８６及び直流スイッチ８７を制御する。 The AC-DC converter 85 converts the alternating current from the AC distributor 84 into direct current. The AC switch 86 is interposed between the AC distributor 84 and the electric connector 89. The DC switch 87 is interposed between the AC-DC converter 85 and the electric connector 89. The ON-OFF controller 88 controls the AC switch 86 and the DC switch 87 based on the signal from the liquid supply switch 16.

　ＡＣ－ＤＣ変換器９５及び定電流回路９６は、ＬＥＤ３９と共にノズル１７に内蔵されている。ＡＣ－ＤＣ変換器９５及び定電流回路９６は、ＬＥＤ３９と受電用コイル５８との間に介在する。 The AC-DC converter 95 and the constant current circuit 96 are built in the nozzle 17 together with the LED 39. The AC-DC converter 95 and the constant current circuit 96 are interposed between the LED 39 and the power receiving coil 58.
　（ワイヤレス給電）
　交流スイッチ８６がオンであるとき、送電用コイル７０は、電気コネクタ８９，９０を介してＡＣ分配器８４からの交流を受け、磁束を変化させる。この磁束変化は、ワイレスでノズル１７の受電用コイル５８に伝わり、受電用コイル５８は交流を生成する。 (Wireless power supply)
When the AC switch 86 is on, the power transmission coil 70 receives alternating current from the AC distributor 84 via the electrical connectors 89 and 90 to change the magnetic flux. This change in magnetic flux is transmitted wirelessly to the power receiving coil 58 of the nozzle 17, and the power receiving coil 58 generates alternating current.
　受電用コイル５８が生成した交流は、ＡＣ－ＤＣ変換器９５において直流に変化される。定電流回路９６は、ＡＣ－ＤＣ変換器９５が出力する直流から定電流を生成し、ＬＥＤ３９に出力する。ＬＥＤ３９は、定電流回路９６から供給された定電流により紫外光を生成する。なお、ＬＥＤ３９は、受電用コイル５８が生成した交流電流を受けて発光するように、複数のＬＥＤを逆並列に接続した構成であってもよい。 The alternating current generated by the power receiving coil 58 is changed to direct current in the AC-DC converter 95. The constant current circuit 96 generates a constant current from the direct current output by the AC-DC converter 95 and outputs the constant current to the LED 39. The LED 39 generates ultraviolet light by the constant current supplied from the constant current circuit 96. The LED 39 may have a configuration in which a plurality of LEDs are connected in antiparallel so as to receive an alternating current generated by the power receiving coil 58 and emit light.

FIG. 8 is a flowchart of the main routine of the liquid control method in the drink server 10.
　ステップＳ１０１では、制御部７６は、ドリンクサーバ１０の電源がオンになったか否かを判定する。制御部７６は、該判定の結果が肯定的（ＹＥＳ）であれば、処理をステップＳ１０２に進め、否定的（ＮＯ）であれば、該判定の結果が肯定的になるまでステップＳ１０１を繰り返す。 In step S101, the control unit 76 determines whether or not the power of the drink server 10 has been turned on. If the result of the determination is positive (YES), the control unit 76 advances the process to step S102, and if the result of the determination is negative (NO), the control unit 76 repeats step S101 until the result of the determination becomes positive.
　次に、制御部７６は、ステップＳ１０２の給液処理ルーチン及びステップＳ１０３の殺菌処理ルーチンを順番に実施する。 Next, the control unit 76 sequentially executes the liquid supply processing routine in step S102 and the sterilization processing routine in step S103.
　ステップＳ１０４では、制御部７６は、ドリンクサーバ１０の電源がオフになったか否かを判定する。制御部７６は、該判定の結果が肯定的であれば、メインルーチンを終了し、否定的であれば、処理をステップＳ１０２に戻す。 In step S104, the control unit 76 determines whether or not the power of the drink server 10 has been turned off. If the result of the determination is positive, the control unit 76 ends the main routine, and if the result of the determination is negative, returns the process to step S102.
　図９は、給液処理ルーチンのフローチャートである。 FIG. 9 is a flowchart of the liquid supply processing routine.
　ステップＳ１１０では、制御部７６は、給液スイッチ１６がオフからオンに切替わったか否かを判定する。制御部７６は、該判定が肯定的であれば、処理をステップＳ１１１に進ませ、否定的であれば、該ルーチンを終了する（メインルーチンに戻る）。 In step S110, the control unit 76 determines whether or not the liquid supply switch 16 has been switched from off to on. If the determination is positive, the control unit 76 advances the process to step S111, and if the determination is negative, the control unit 76 ends the routine (returns to the main routine).
　ステップＳ１１１では、制御部７６は、ワイヤレス給電を強制的に終了させる。制御部７６は、具体的には、給電切替部７７（交流スイッチ８６）をオフにして、ワイヤレス給電を強制的に終了させる。これは、給液スイッチ１６がオンに切り替わったときにワイヤレス給電が実施されていた場合にこれを終了させるためのステップである。 In step S111, the control unit 76 forcibly terminates the wireless power supply. Specifically, the control unit 76 turns off the power supply switching unit 77 (AC switch 86) to forcibly terminate the wireless power supply. This is a step for terminating the wireless power supply when the liquid supply switch 16 is switched on.
　ステップＳ１１２では、ポンプ駆動部７５は、ポンプ３３の駆動を開始する。ポンプ駆動部７５は、具体的には、直流スイッチ８７をオンにして、ポンプ３３への駆動電流を供給開始することによりポンプ３３の駆動を開始する。 In step S112, the pump drive unit 75 starts driving the pump 33. Specifically, the pump drive unit 75 starts driving the pump 33 by turning on the DC switch 87 and starting to supply the drive current to the pump 33.
　ステップＳ１１３では、ポンプ駆動部７５は、ポンプ３３の駆動時間Ｔｏが所定値Ｃｐを超えたか否かを判定する。Ｔｏ＝Ｃｐは、図１においてノズル１７からの飲み物１８の放出量が所定値に達し、カップ１５内に規定量の飲み物１８が供給されたことを意味する。 In step S113, the pump drive unit 75 determines whether or not the drive time To of the pump 33 exceeds the predetermined value Cp. To = Cp means that the amount of the drink 18 released from the nozzle 17 in FIG. 1 has reached a predetermined value, and the specified amount of the drink 18 has been supplied into the cup 15.
　ポンプ駆動部７５は、ステップＳ１１３の判定が肯定的になるまで、ステップＳ１１３の判定を繰り返す。そして、該判定が肯定的になりしだい、処理をステップＳ１１４に進める。 The pump drive unit 75 repeats the determination in step S113 until the determination in step S113 becomes affirmative. Then, as soon as the determination becomes positive, the process proceeds to step S114.
　ステップＳ１１４では、ポンプ駆動部７５は、ポンプ３３の駆動を終了する。これにより、ノズル１７からカップ１５への飲み物１８の放出が停止する。ステップＳ１１５では、制御部７６は、ワイヤレス給電の強制停止を解除する。 In step S114, the pump drive unit 75 ends the drive of the pump 33. As a result, the discharge of the drink 18 from the nozzle 17 to the cup 15 is stopped. In step S115, the control unit 76 releases the forced stop of the wireless power supply.
　ノズル１７からの飲み物１８の放出は、途絶えるものの、一部の飲み物１８がノズル１７から放出されることなく、ノズル１７の受液通路３８に付着して残る。このようにして残った飲み物１８は、次の給液スイッチ１６のオン操作時に次に放出される飲み物１８と混ざって、ノズル１７から放出される。 Although the discharge of the drink 18 from the nozzle 17 is interrupted, a part of the drink 18 remains attached to the liquid receiving passage 38 of the nozzle 17 without being discharged from the nozzle 17. The drink 18 remaining in this way is mixed with the drink 18 to be discharged next when the next liquid supply switch 16 is turned on, and is discharged from the nozzle 17.
　しかしながら、次の給液スイッチ１６のオン操作時までの時間間隔が長くなると、残液中で菌が繁殖して、飲み物１８の品質低下につながることがある。さらには、ノズル１７の内面の受液通路３８に残液がなくても、結露により大気中の水蒸気が受液通路３８に付着して、菌が繁殖することがある。その菌は、次の飲み物１８の放出時に該次の飲み物１８に混ざるので、これも飲み物１８の品質低下につながる。 However, if the time interval until the next on operation of the liquid supply switch 16 becomes long, bacteria may propagate in the residual liquid, leading to deterioration of the quality of the drink 18. Further, even if there is no residual liquid in the liquid receiving passage 38 on the inner surface of the nozzle 17, water vapor in the atmosphere may adhere to the liquid receiving passage 38 due to dew condensation and bacteria may propagate. Since the bacteria are mixed with the next drink 18 when the next drink 18 is released, this also leads to a deterioration in the quality of the drink 18.
　したがって、ノズル１７からの飲み物１８の非放出期間において定期的に紫外光を残液に照射して、殺菌することが望ましい。殺菌処理は、次の図１０の殺菌処理ルーチンで説明する。 Therefore, it is desirable to sterilize the residual liquid by periodically irradiating the residual liquid with ultraviolet light during the non-emission period of the drink 18 from the nozzle 17. The sterilization process will be described in the sterilization process routine of FIG. 10 below.
　制御部７６は、ステップＳ１１６において給電タイマーの計測時間Ｔｃをリセットする。給電タイマーは、カウンタから構成され、リセットされてからの経過時間を計測する（図１０のステップＳ１２４）。給電タイマーは、次の図１０の殺菌処理ルーチンにおいてワイヤレス給電部８０の非給電期間の長さを検出するために用いられる。 The control unit 76 resets the measurement time Tc of the power supply timer in step S116. The power supply timer is composed of a counter and measures the elapsed time since it was reset (step S124 in FIG. 10). The power supply timer is used to detect the length of the non-power supply period of the wireless power supply unit 80 in the sterilization processing routine of FIG. 10 below.
　図１０は、殺菌処理ルーチンのフローチャートである。 FIG. 10 is a flowchart of the sterilization processing routine.
　ステップＳ１２１では、制御部７６は、計測時間Ｔｃが所定値Ｃ１を超えたか否かを判定する。所定値Ｃ１は、菌の世代交代の時間として予め記憶部７８に記憶されている。 In step S121, the control unit 76 determines whether or not the measurement time Tc exceeds the predetermined value C1. The predetermined value C1 is stored in advance in the storage unit 78 as the time for the alternation of generations of the bacteria.
　ノズル１７からの紫外光の非照射時間の長さが所定値Ｃ１を超えてしまうと、ノズル１７の受液通路３８における残液内の菌が大量に増殖してしまい、紫外光の照射時間を大幅に増大させるか、紫外光の強度を大幅に増大させる必要が生じる。したがって、効率的な殺菌処理のためには、Ｃ１より短い時間間隔で紫外光を残液に照射すればよい。 If the length of the non-irradiation time of the ultraviolet light from the nozzle 17 exceeds the predetermined value C1, a large amount of bacteria in the residual liquid in the liquid receiving passage 38 of the nozzle 17 will proliferate, and the irradiation time of the ultraviolet light will be increased. It will be necessary to increase it significantly or increase the intensity of ultraviolet light significantly. Therefore, for efficient sterilization treatment, the residual liquid may be irradiated with ultraviolet light at intervals shorter than C1.
　制御部７６は、ステップＳ１２１の判定が肯定的であれば、処理をステップＳ１２２に進ませ、否定的であれば、ステップＳ１２４に進む。 If the determination in step S121 is positive, the control unit 76 advances the process to step S122, and if it is negative, proceeds to step S124.
　ステップＳ１２２では、制御部７６は、ワイヤレス給電を一定時間、実施する。 In step S122, the control unit 76 executes wireless power supply for a certain period of time.
　具体的には、制御部７６は、給電切替部７７（交流スイッチ８６）をオンに切り替えて、送電用コイル７０に交流を供給することによりワイヤレス給電を開始し、給電切替部７７をオフに切り替えて、送電用コイル７０への交流の供給を中止することによりワイヤレス給電を終了する。 Specifically, the control unit 76 switches the power supply switching unit 77 (AC switch 86) on, starts wireless power supply by supplying AC to the power transmission coil 70, and switches the power supply switching unit 77 off. Then, the wireless power supply is terminated by stopping the supply of alternating current to the power transmission coil 70.
　ステップＳ１２３では、制御部７６は、給電タイマーの計測時間Ｔｃをリセットする。 In step S123, the control unit 76 resets the measurement time Tc of the power supply timer.
　ステップＳ１２４では、制御部７６は、計測時間Ｔｃを計測する。具体的には、給電タイマーのカウンタ値を１だけインクリメントする。こうして、給電タイマーのカウンタ値は、給電タイマーがリセットされた時刻から一定時間が経過するごとに１、インクリメントされる。ステップＳ１２４の処理が実行された後、処理は、メインルーチンに戻される。 In step S124, the control unit 76 measures the measurement time Tc. Specifically, the counter value of the power supply timer is incremented by 1. In this way, the counter value of the power supply timer is incremented by 1 every time a certain time elapses from the time when the power supply timer is reset. After the processing of step S124 is executed, the processing is returned to the main routine.
