しかしながら、飲料供給装置を設置して最初に使用を開始する時は、湯ポンプには湯が導入されていないために空運転となり、湯ポンプがギヤポンプである場合には潤滑の働きをする湯がない状態でギヤを高速回転してギヤの歯面に異常磨耗を生じる虞がある。また、電磁ポンプの場合にはピストンにかかる負荷が小さいために、電磁プランジャおよびピストンがフルストロークで往復動をおこし、電磁プランジャと共に往復動するピストンを支持する上ばねと下ばねに無理な伸縮が要求されることとなり、ばねに異常衝撃荷重が加わり破損を招く虞がある。このように、ギヤポンプのギヤ歯面の異常磨耗、また、電磁ポンプの電磁プランジャと共に往復動するピストンを支持する上ばねまた下ばねの破損が生じると、抽出機のシリンダ内に高圧の湯を供給することができなくなり、飲料供給装置がコーヒー飲料を調理して供給することができなくなる。   However, when the beverage supply device is first installed and used for the first time, no hot water is introduced into the hot water pump, so that the hot operation is performed. If there is no gear, the gear may rotate at a high speed to cause abnormal wear on the gear teeth. In the case of an electromagnetic pump, since the load applied to the piston is small, the electromagnetic plunger and the piston reciprocate at full stroke, and the upper and lower springs that support the piston reciprocating together with the electromagnetic plunger do not expand or contract excessively. As a result, the spring may be damaged due to an abnormal impact load. As described above, when abnormal wear of the gear tooth surface of the gear pump occurs, or when the upper spring or lower spring supporting the piston reciprocating with the electromagnetic plunger of the electromagnetic pump is damaged, high pressure hot water is supplied into the cylinder of the extractor. And the beverage supply device cannot cook and supply the coffee beverage.

本発明は、上記実情に鑑みて、飲料供給装置の使用開始時に、ポンプに湯が導入されていない状態からポンプを駆動した場合にも、ポンプに不具合を生じさせることなくコーヒー飲料を供給可能な飲料供給装置を提供することを目的とする。   In view of the above circumstances, the present invention can supply a coffee beverage without causing a malfunction of the pump even when the pump is driven from the state where hot water is not introduced into the pump at the start of use of the beverage supply device. It aims at providing a drink supply apparatus.

また、本発明の請求項２に係る飲料供給装置は、上述した請求項１において、前記制御手段は、前記電磁ポンプを駆動開始時に、その駆動定格値より小さい駆動力で所定時間駆動後、駆動定格値で駆動するように前記ポンプ電源を制御することを特徴とする。   The beverage supply apparatus according to claim 2 of the present invention is the beverage supply apparatus according to claim 1, wherein the control means drives the electromagnetic pump after driving for a predetermined time with a driving force smaller than a rated drive value when starting to drive the electromagnetic pump. The pump power supply is controlled to drive at a rated value.

請求項１の発明によれば、飲料供給装置に、原料および水を用いて飲料を調理する飲料調理機と、飲料を供給する時に水を圧送する電磁ポンプと、電磁ポンプが圧送した水を加熱して飲料調理機に供給するボイラと、電磁ポンプを駆動するポンプ電源と、ポンプ電源を制御する制御手段と、を備えたので、飲料供給装置の使用開始時に、ポンプに湯が導入されていない状態からポンプを駆動した場合にも、ポンプに不具合を生じさせることなくコーヒー飲料を供給可能な飲料供給装置を実現することができる。
請求項２の発明によれば、制御手段が、電磁ポンプを駆動開始時にその駆動定格値より小さい駆動力で所定時間駆動後、駆動定格値で駆動するように前記ポンプ電源を制御すると、駆動開始時の電磁コイルの励磁力が小さくなり、電磁プランジャがピストンと共に磁気吸引力で磁気ロッドへ吸引される吸引力が弱くなる。これにより、電磁ポンプ空運転時の電磁プランジャおよびピストンのフルストローク往復動による上ばねと下ばねが急激な伸縮を要求されることがなく、ばねに異常衝撃荷重が加わることもなくなり、ばね破損をなくすることができる。 According to the first aspect of the present invention, a beverage cooker that cooks beverages using raw materials and water, an electromagnetic pump that pumps water when supplying the beverage, and water pumped by the electromagnetic pump are heated to the beverage supply device.

According to the invention of claim 2, when the control means controls the pump power supply so that the electromagnetic pump is driven at a driving rated value after driving for a predetermined time with a driving force smaller than the driving rated value at the start of driving, the driving starts. The exciting force of the electromagnetic coil at the time becomes small, and the attractive force that the electromagnetic plunger is attracted to the magnetic rod by the magnetic attractive force together with the piston becomes weak. As a result, the upper and lower springs are not required to suddenly expand and contract due to the full stroke reciprocation of the electromagnetic plunger and piston during the idling operation of the electromagnetic pump. Can be eliminated.

FIG. 2 shows a cross-sectional side view of the electromagnetic pump 20 of the beverage supply device 1 according to one embodiment of the present invention. The electromagnetic pump 20 is provided with an electromagnetic coil 22 to which a current is applied in a case 21 made of a magnetic material such as iron.

上記構成における電磁ポンプ２０は、電磁コイル２２に所定のパルス数（例えば、５０ＨＺ）のパルス電流が印加されると、電磁コイル２２が励磁され、電磁プランジャ２６、電磁ロッド２３、ケース２１で磁気回路が構成され、電磁プランジャ２６の上端がＮ極、下端がＳ極となって、電磁プランジャ２６は磁気吸引力にて磁気ロッド２３へ上ばね２９に抗して吸引される。そして、電磁コイル２２が消磁されると、吸磁力が消滅して上ばね２９の反発力で下方へ戻される。このような繰り返しにより電磁プランジャ２６は往復動されることになる。 The electromagnetic plunger 26 is formed in a substantially cylindrical shape by a magnetic material such as iron, and a piston 27 is inserted into a free cylinder 28 at a lower portion thereof.

When the electromagnetic coil 22 is demagnetized, the attractive force disappears and is returned downward by the repulsive force of the upper spring 29. The electromagnetic plunger 26 is reciprocated by such repetition.

この電磁プランジャ２６の上昇と共にピストン２７が上昇すると、ポンプ室３３内の圧力が低下して吸入弁３１を開いて吸入ロッド３４の吸入口３４ａから水を吸入し、ピストン２７が下降するとポンプ室３３内の圧力が上昇して吐出弁３２を開いて水を吐出させ、水は流出孔３５から電磁プランジャの中心を縦方向に貫通する貫通孔２６ａ、貫通孔２３ａを介して吐出側の流路となる吐出ロッド２５の吐出口２５ａへ送り出される。
図３は、本発明の一実施形態による飲料供給装置１の制御ブロック図を示す。電磁ポンプ２０からボイラ４０に流れた水量を計測して計測信号を出力する流量計１３と、ボイラ本体４１内の湯の温度を検出し、その検出信号を出力するボイラ湯温センサ４３と、飲料を供給するための制御を行う制御装置８０（制御手段）と、制御装置８０が出力する信号で各々動作する、制御装置８０によって制御されるポンプ電源９０からの通電によって水をボイラ４０に供給する電磁ポンプ２０と、電源９２からの通電によってボイラ本体４１内の水を加熱するヒータ４２と、弁を開放してボイラ本体４１内にたまっている空気を抜くエア抜き弁１５と、飲料を供給する給湯時に弁を開放してボイラ４０で加熱された高圧の湯をコーヒー抽出機５０に供給する抽出弁１６と、供給されたコーヒー豆および湯を用いてコーヒーを抽出するコーヒー抽出機５０と、飲料供給装置１各部の制御データを記憶するメモリ（記憶手段）８１と、基準クロック発生部（図示せず）で発生するクロックをカウントして時間を計測するタイマー８２を有する。 When the piston 27 rises as the electromagnetic plunger 26 rises, the pressure in the pump chamber 33 decreases, the suction valve 31 opens, water is sucked from the suction port 34a of the suction rod 34, and when the piston 27 descends, the pump chamber 33 The internal pressure rises, and the discharge valve 32 is opened to discharge water. The water passes through the outlet hole 35 in the longitudinal direction through the center of the electromagnetic plunger through the through hole 26a and the through hole 23a.

図４は、本発明の一実施形態による飲料供給装置１を設置して最初に使用を開始する時の電磁ポンプ２０に印可するパルス電流の電圧値を示し、電磁ポンプ２０駆動開始時のパルス電流は、電磁ポンプ２０の駆動定格値より小さい駆動力（例えば、定格パルス電圧の５０％の電圧値）で所定時間（例えば、１５秒間）パルス電流を印可して電磁ポンプ２０内に水を導入し、その後定格パルス電圧を印可して駆動するようにしている。このように、飲料供給装置１を設置しての電磁ポンプ２０に水が導入されていない駆動開始時の空運転の状態では、電磁コイル２２に供給するパルス電流の電圧値を駆動定格値より小さくして、電磁コイル２２の励磁力を小さくすると、電磁プランジャ２６、電磁ロッド２３、ケース２１で構成する磁気回路の磁気吸引力が小さくなり、電磁プランジャ２６がピストン２７と共に磁気吸引力で磁気ロッド２３へ吸引される吸引力が弱くなる。これにより、電磁ポンプ２０空運転時の電磁プランジャ２６およびピストン２７のフルストローク往復動による上ばね２９と下ばね３０が急激な伸縮を要求されることがなく、ばねに異常衝撃荷重が加わることもなくなり、ばね破損を招くようなこともなくなる。   FIG. 4 shows the voltage value of the pulse current applied to the electromagnetic pump 20 when the beverage supply device 1 according to the embodiment of the present invention is installed and first used, and the pulse current at the start of driving the electromagnetic pump 20 Applies a pulse current for a predetermined time (for example, 15 seconds) with a driving force (for example, a voltage value of 50% of the rated pulse voltage) smaller than the rated driving value of the electromagnetic pump 20 to introduce water into the electromagnetic pump 20. Then, the rated pulse voltage is applied to drive. Thus, in the idling state at the start of driving when water is not introduced into the electromagnetic pump 20 with the beverage supply device 1 installed, the voltage value of the pulse current supplied to the electromagnetic coil 22 is smaller than the drive rated value. When the exciting force of the electromagnetic coil 22 is reduced, the magnetic attractive force of the magnetic circuit constituted by the electromagnetic plunger 26, the electromagnetic rod 23, and the case 21 is reduced. The suction power that is sucked into is weakened. Accordingly, the upper spring 29 and the lower spring 30 due to full stroke reciprocation of the electromagnetic plunger 26 and the piston 27 during the idling operation of the electromagnetic pump 20 are not required to be rapidly expanded and contracted, and an abnormal impact load is applied to the spring. This eliminates the possibility of spring breakage.

以上説明したように、本発明の実施の形態に係る飲料供給装置によれば、飲料供給装置使用開始時のポンプに湯水が導入されていない空運転の状態からポンプを駆動した場合にも、ポンプに不具合を生じさせることなくコーヒー飲料を供給可能な飲料供給装置を提供することができる。   As described above, according to the beverage supply device according to the embodiment of the present invention, even when the pump is driven from the idle operation state where hot water is not introduced into the pump at the start of use of the beverage supply device, the pump It is possible to provide a beverage supply device that can supply a coffee beverage without causing any problems.
