Although the water temperature (upper limit value and lower limit value) is set to the same water temperature, the present invention is not limited to this, and the upper limit value and lower limit value of the optimal water temperature region in the drinking water supply pipe 7 The water temperature (upper limit value and lower limit value) that triggers opening and closing of the electromagnetic valve 9 may be set as a different water temperature.

冬季などに温茶などを製造する場合には、制御装置10を冬季モードに設定しておく。冬季モードにおいては、タンク内温度センサ14によって検知された飲料水(お茶)の水温が例えば75℃〜85℃の水温域の範囲内に維持されるように制御装置10がプラグヒータ15を制御する。この貯留タンク6内の水温域を飲料水供給管7内の最適な水温域である70℃〜80℃よりも高い水温域の範囲内とするのは、貯留タンク6から飲料水供給管7内に供給されるうちに温茶が若干冷めてしまうことを考慮しているからである。   When manufacturing warm tea or the like in winter, the control device 10 is set to the winter mode. In the winter mode, the control device 10 controls the plug heater 15 so that the water temperature of the drinking water (tea) detected by the tank temperature sensor 14 is maintained within a water temperature range of 75 ° C. to 85 ° C., for example. . The water temperature range in the storage tank 6 is set within the range of the water temperature range higher than 70 ° C. to 80 ° C., which is the optimum water temperature range in the drinking water supply pipe 7, from the storage tank 6 to the drinking water supply pipe 7. This is because it is considered that warm tea gets slightly cooled while it is being supplied.

図2に示すように、冷却器16の内部には、飲料水供給管7が配設されるとともに、冷媒用のガスを密閉した冷却パイプ(図示略)が設けられており、冷却パイプ(図示略)と飲料水供給管7との間で熱交換が行われるようになっている。   As shown in FIG. 2, a drinking water supply pipe 7 is disposed inside the cooler 16, and a cooling pipe (not shown) in which a refrigerant gas is sealed is provided. The heat exchange is performed between the abbreviated) and the drinking water supply pipe 7.

夏季などに冷茶などを製造する場合には、制御装置10を夏季モードに設定しておく。夏季モードにおいては、飲料水(お茶)の水温が冷却器16を通過する際に、1℃〜6℃の水温域の範囲内に冷却されて供給されるようになっている。この冷却器16を通過する飲料水の水温域を飲料水供給管7内の最適な水温域である3℃〜8℃よりも低い水温域である1℃〜6℃の範囲内とするのは、冷却器16から飲料水供給管7内に供給されるうちに冷茶が若干温まってしまうことを考慮しているからである。   When manufacturing cold tea or the like in summer, the control device 10 is set to summer mode. In the summer mode, when the water temperature of the drinking water (tea) passes through the cooler 16, it is cooled and supplied within the range of the water temperature range of 1 ° C to 6 ° C. The water temperature range of the drinking water passing through the cooler 16 is set within the range of 1 ° C. to 6 ° C., which is a water temperature range lower than 3 ° C. to 8 ° C. which is the optimum water temperature range in the drinking water supply pipe 7. This is because it is considered that the cold tea is slightly warmed while being supplied from the cooler 16 into the drinking water supply pipe 7.

また、図2に示すように、飲料水供給管7の下流側に設けられた電磁バルブ9の近傍には、電磁バルブ9より上流側にある飲料水供給管7内の飲料水(お茶)の水圧を検知する圧力検知手段としての圧力センサ17が設けられているとともに、飲料水供給管7内の飲料水の水温を検知する温度検知手段としての管内温度センサ18が設けられており、これら圧力センサ17と管内温度センサ18は制御装置10に接続されている。   In addition, as shown in FIG. 2, in the vicinity of the electromagnetic valve 9 provided on the downstream side of the drinking water supply pipe 7, drinking water (tea) in the drinking water supply pipe 7 on the upstream side of the electromagnetic valve 9 is provided. A pressure sensor 17 is provided as pressure detecting means for detecting the water pressure, and an in-pipe temperature sensor 18 is provided as temperature detecting means for detecting the temperature of the drinking water in the drinking water supply pipe 7, and these pressures are provided. The sensor 17 and the pipe temperature sensor 18 are connected to the control device 10.

更に図2に示すように、供給ポンプ8はインバータ19を介して制御装置10に制御されるようになっており、インバータ19を介することで電源の周波数と電圧が制御され、供給ポンプ8のモータ回転速度(出力)が制御されている。   Further, as shown in FIG. 2, the supply pump 8 is controlled by the control device 10 via the inverter 19, and the frequency and voltage of the power supply are controlled via the inverter 19, and the motor of the supply pump 8 is controlled. The rotation speed (output) is controlled.

また、供給ポンプ8は常に駆動されており、通常運転時に適用されるLowモードと、多数のグラスフィラ4から同時に飲料水(お茶)が抽出されるとき、すなわち、水圧が低下したときに適用され、Lowモードよりもモータ回転速度が速いHighモードとの2段階のモータ回転速度を切り換えて駆動されるようになっている。具体的には、前記Lowモードは、例えば通常時等において少数のグラスフィラ4が使用されているときに飲料水供給管7内の水圧を予め定められた0.3Mpa以上に維持させることができるモータ回転速度に供給ポンプ8が制御されるモードであり、前記Highモードは、例えば繁忙期等において多数のグラスフィラ4が使用されて水圧が0.3Mpa以下となったときに、該水圧を0.3Mpa以上まで上昇させることができるモータ回転速度に供給ポンプ8が制御されるモードである。   The supply pump 8 is always driven, and is applied when the low mode applied during normal operation and when drinking water (tea) is simultaneously extracted from many glass fillers 4, that is, when the water pressure is reduced. The motor is driven by switching the two-stage motor rotation speed with the High mode, where the motor rotation speed is faster than the Low mode. Specifically, the Low mode can maintain the water pressure in the drinking water supply pipe 7 at a predetermined 0.3 Mpa or more when, for example, a small number of glass fillers 4 are used in normal times. In this mode, the supply pump 8 is controlled at the motor rotation speed, and the High mode reduces the water pressure to 0 when the water pressure becomes 0.3 Mpa or less when a large number of glass fillers 4 are used in a busy season, for example. In this mode, the supply pump 8 is controlled at a motor rotation speed that can be increased to 3 Mpa or more.

このように本実施例1における制御装置10は、飲料水供給管7内の水圧が予め定められた0.3Mpa以上であるときには供給ポンプ8をLowモードにて駆動させる制御を行い、例えば多数のグラスフィラ4が使用されるなどして管内の水圧が0.3Mpa以下であるときには供給ポンプ8をHighモードにて駆動させる後述する供給ポンプ制御処理を行う。   As described above, the control device 10 according to the first embodiment performs control to drive the supply pump 8 in the low mode when the water pressure in the drinking water supply pipe 7 is equal to or higher than a predetermined 0.3 Mpa. When the glass filler 4 is used and the water pressure in the pipe is 0.3 Mpa or less, a supply pump control process to be described later for driving the supply pump 8 in the High mode is performed.

また、制御装置10は、飲料水供給管7内の水圧が予め定められた0.3Mpa以下であり、かつ、飲料水供給管7内の水温が冬季モードにおける上限値である80℃以上であるときまたは飲料水供給管7内の水温が夏季モードにおける下限値である3℃以下であるときに電磁バルブ9を閉鎖させるとともに、飲料水供給管7内の水温が冬季モードにおける下限値である70℃以下であるとき並びに飲料水供給管7内の水温が夏季モードにおける上限値である8℃以上であるときに電磁バルブ9を開放させる後述する電磁バルブ制御処理を行う。   In addition, the control device 10 has a water pressure in the drinking water supply pipe 7 of not more than a predetermined 0.3 Mpa, and the water temperature in the drinking water supply pipe 7 is not less than 80 ° C., which is the upper limit value in the winter mode. When the water temperature in the drinking water supply pipe 7 is 3 ° C. or lower which is the lower limit value in the summer mode, the electromagnetic valve 9 is closed, and the water temperature in the drinking water supply pipe 7 is the lower limit value in the winter mode 70 When the temperature is not higher than ° C. and when the water temperature in the drinking water supply pipe 7 is equal to or higher than 8 ° C., which is the upper limit value in the summer mode, an electromagnetic valve control process, which will be described later, is performed.

例えば多数のグラスフィラ4が使用されるなどして管内の水圧が0.3Mpa以下であるときには、各グラスフィラ4からの飲料水の流出量が弱まるため、水圧を上昇させるために供給ポンプ8による飲料水の供給量を増加させる供給ポンプ制御処理が行われるとともに、管内の水温が、冬季モードにおいて所定水温(70℃)以下であるとき、夏季モードにおいて所定水温(8℃)以上であるときには、最適な水温の飲料水が飲食客に提供されないため、電磁バルブ9を開放させて貯留タンク6内にて生成された水温の飲料水の供給量を増大して循環させ、飲料水供給管7内全体の水温を短時間で前記所定の水温域の範囲内に維持するための電磁バルブ制御処理が行われる。   For example, when a large number of glass fillers 4 are used and the water pressure in the pipe is 0.3 Mpa or less, the outflow amount of drinking water from each glass filler 4 is weakened, so that the supply pump 8 increases the water pressure. When the supply pump control process for increasing the supply amount of drinking water is performed and the water temperature in the pipe is equal to or lower than the predetermined water temperature (70 ° C.) in the winter mode, or when the water temperature is equal to or higher than the predetermined water temperature (8 ° C.) in the summer mode, Since the drinking water having the optimum water temperature is not provided to the eating and drinking customers, the electromagnetic valve 9 is opened and the supply amount of the drinking water having the water temperature generated in the storage tank 6 is increased and circulated, so that the drinking water supply pipe 7 An electromagnetic valve control process is performed to maintain the entire water temperature within the predetermined water temperature range in a short time.

つまり、制御装置10は、圧力検知手段としての圧力センサ17による水圧の検知に基づいて、飲料水供給管7内の水圧が前記所定の水圧域に維持されるように流量調節手段としての電磁バルブ9を制御する第1の流量調節制御手段と、温度検知手段としての管内温度センサ18による水温の検知に基づいて、飲料水供給管7内の水温が所定の水温域に維持されるように流量調節手段としての電磁バルブ9を制御する第2の流量調節制御手段とを構成している。   That is, the control device 10 uses the electromagnetic valve as the flow rate adjusting means so that the water pressure in the drinking water supply pipe 7 is maintained in the predetermined water pressure region based on the detection of the water pressure by the pressure sensor 17 as the pressure detecting means. On the basis of detection of the water temperature by the first flow rate adjustment control means for controlling 9 and the in-pipe temperature sensor 18 as the temperature detection means, the flow rate is set so that the water temperature in the drinking water supply pipe 7 is maintained in a predetermined water temperature range. It constitutes a second flow rate adjustment control means for controlling the electromagnetic valve 9 as the adjustment means.

また、本実施例においては、冬季モードにおいて所定水温(70℃)以下であるとき、または夏季モードにおいて所定水温(8℃)以上であるときにおいて、管内の水圧が0.3Mpa以下であるときには前記水温に基づく電磁バルブ9を開放させる制御は行われないようになっている。すなわち、水温に基づく電磁バルブ制御処理よりも水圧に基づく電磁バルブ制御処理が優先して行われるようになっている。   Further, in the present embodiment, when the water pressure in the pipe is 0.3 Mpa or less when the water temperature is not more than a predetermined water temperature (70 ° C.) in the winter mode or when the water temperature is not less than the predetermined water temperature (8 ° C.) in the summer mode. Control for opening the electromagnetic valve 9 based on the water temperature is not performed. That is, the electromagnetic valve control process based on the water pressure is preferentially performed over the electromagnetic valve control process based on the water temperature.

つまり、制御装置10は、管内温度センサ18による水温の検知に基づく電磁バルブ9の制御よりも、圧力センサ17による水圧の検知に基づく電磁バルブ9の制御を優先して行わせる優先制御手段を構成している。   That is, the control device 10 constitutes priority control means for giving priority to the control of the electromagnetic valve 9 based on the detection of the water pressure by the pressure sensor 17 over the control of the electromagnetic valve 9 based on the detection of the water temperature by the pipe temperature sensor 18. is doing.

尚、本実施例においては、水温に基づく電磁バルブ制御処理よりも水圧に基づく電磁バルブ制御処理を優先して行うようにしているが、水圧に基づく電磁バルブ制御処理よりも水温に基づく電磁バルブ制御処理を優先して行うようにしてもよい。   In this embodiment, the electromagnetic valve control process based on the water pressure is prioritized over the electromagnetic valve control process based on the water temperature, but the electromagnetic valve control based on the water temperature is performed rather than the electromagnetic valve control process based on the water pressure. Processing may be performed with priority.

ここで、本実施例における制御装置10が実行する供給ポンプ制御処理の制御内容を、図3のフローチャートに基づいて以下に説明すると、制御装置10は、圧力センサ17により検知された水圧に基づいて、飲料水供給管7内の飲料水(お茶)の水圧が設定された水圧(0.3Mpa)以下であるか否か判定し(Sa01)、飲料水供給管7内の飲料水の水圧が設定された水圧(0.3Mpa)以上ならば、Lowモードで供給ポンプ8を駆動させる(Sa03)。   Here, the control content of the supply pump control process executed by the control device 10 in the present embodiment will be described below based on the flowchart of FIG. 3. The control device 10 is based on the water pressure detected by the pressure sensor 17. It is determined whether or not the water pressure of the drinking water (tea) in the drinking water supply pipe 7 is equal to or lower than the set water pressure (0.3 Mpa) (Sa01), and the drinking water pressure in the drinking water supply pipe 7 is set. If it is equal to or higher than the water pressure (0.3 Mpa), the supply pump 8 is driven in the low mode (Sa03).

尚、Lowモードで供給ポンプ8を駆動させたときには、飲料水供給管7内の水圧が設定された水圧(0.3Mpa)よりも若干高めになり、グラスフィラ4の使用数が少ないときには、供給ポンプ8がLowモードで駆動されても飲料水供給管7内の水圧が、設定された水圧(0.3Mpa)よりも下がらないようになっている。   When the supply pump 8 is driven in the low mode, the water pressure in the drinking water supply pipe 7 is slightly higher than the set water pressure (0.3 Mpa), and when the number of glass fillers 4 used is small, supply is performed. Even if the pump 8 is driven in the Low mode, the water pressure in the drinking water supply pipe 7 does not drop below the set water pressure (0.3 Mpa).

また、例えば店内の客の数が増え、複数配置設けられたグラスフィラ4の使用数が増えること等により、Sa01のステップにおいて、飲料水供給管7内の飲料水の水圧が設定された水圧(0.3Mpa)以下であると判定した場合、制御装置10が供給ポンプ8をHighモードで駆動させる(Sa02)。   In addition, for example, the number of customers in the store increases, and the number of glass fillers 4 provided in a plurality is increased. Thus, in the step of Sa01, the water pressure (the water pressure at which the drinking water supply pressure in the drinking water supply pipe 7 is set ( When it is determined that the pressure is 0.3 MPa or less, the control device 10 drives the supply pump 8 in the high mode (Sa02).

このように供給ポンプ8がHighモードに切り換わると、大量の飲料水が飲料水供給管7内に供給されて飲料水供給管7内の水圧が上がり、設定された水圧(0.3Mpa)に近づくようになる。そのためグラスフィラ4から流出される飲料水の流出量が弱まることを防ぐことができる。   When the supply pump 8 is switched to the high mode in this way, a large amount of drinking water is supplied into the drinking water supply pipe 7 to increase the water pressure in the drinking water supply pipe 7 and to a set water pressure (0.3 Mpa). Get closer. Therefore, it can prevent that the outflow amount of the drinking water which flows out out of the glass filler 4 weakens.

また、グラスフィラ4の使用数が減ったときに供給ポンプ8がHighモードで駆動されていると、飲料水供給管7内の水圧が設定された水圧(0.3Mpa)以上に上がるため、図3に示すSa01のステップにおいて、飲料水供給管7内の飲料水の水圧が設定された水圧(0.3Mpa)以下ではないと判定されると、制御装置10が供給ポンプ8をLowモードで駆動させ、水圧を安定させることになる。   In addition, when the supply pump 8 is driven in the high mode when the number of glass fillers 4 is reduced, the water pressure in the drinking water supply pipe 7 rises to a set water pressure (0.3 Mpa) or more. In step Sa01 shown in FIG. 3, when it is determined that the drinking water pressure in the drinking water supply pipe 7 is not lower than the set water pressure (0.3 Mpa), the control device 10 drives the supply pump 8 in the low mode. To stabilize the water pressure.

次に、本実施例における制御装置10が実行する電磁バルブ制御処理の制御内容を、図4のフローチャートに基づいて以下に説明すると、制御装置10は、圧力センサ17によって検知された飲料水供給管7内の水圧が、設定された水圧(本実施例では0.3Mpa)以下であるか否かを判定し(Sb01)、飲料水供給管7内の飲料水の水圧が設定された水圧(0.3Mpa)以下ならば電磁バルブ9を閉鎖して当該処理を終了する(Sb02)。   Next, the control content of the electromagnetic valve control process executed by the control device 10 in the present embodiment will be described below based on the flowchart of FIG. 4. The control device 10 detects the drinking water supply pipe detected by the pressure sensor 17. 7 is determined whether or not the water pressure in the drinking water is equal to or lower than the set water pressure (0.3 Mpa in this embodiment) (Sb01), and the drinking water pressure in the drinking water supply pipe 7 is set to the set water pressure (0 .3 MPa), the electromagnetic valve 9 is closed and the process is terminated (Sb02).

また、Sb01のステップにおいて、飲料水供給管7内の飲料水の水圧が設定された水圧(0.3Mpa)以下ではないと判定したときは、電磁バルブ9の制御を行うことなくSb03に進み、冬季モードに設定されているか否かを判定し(Sb03)、Sb03において冬季モードに設定されていると判定したときには、管内温度センサ18によって検知された飲料水供給管7内の飲料水(温茶)の水温が、冬季モードで設定された水温域の下限値(70℃)以下であるか否か、すなわち、飲食客に提供される飲料水(温茶)の水温が適温以下であるか否かを判定し(Sb04)、飲料水の水温が水温域の下限値(70℃)以下ならば、電磁バルブ9を開放する(Sb05)。   If it is determined in step Sb01 that the water pressure of the drinking water in the drinking water supply pipe 7 is not lower than the set water pressure (0.3 Mpa), the process proceeds to Sb03 without controlling the electromagnetic valve 9. It is determined whether or not the winter mode is set (Sb03). When it is determined that the winter mode is set in Sb03, the drinking water (warm tea) in the drinking water supply pipe 7 detected by the pipe temperature sensor 18 is determined. ) Is below the lower limit (70 ° C.) of the water temperature range set in the winter mode, that is, whether the water temperature of the drinking water (warm tea) provided to the restaurant is below the appropriate temperature. If the water temperature of the drinking water is equal to or lower than the lower limit value (70 ° C.) of the water temperature range, the electromagnetic valve 9 is opened (Sb05).

Sb05のステップにおいて電磁バルブ9が開放されると、貯留タンク6内で温められた75℃〜85℃の飲料水(温茶)が飲料水供給管7内に循環供給され、これにより、複数のグラスフィラ4が使用されているか否かに関わらず、飲料水供給管7内の飲料水の水温が急速に上昇することになる。   When the electromagnetic valve 9 is opened in step Sb05, drinking water (warm tea) of 75 ° C. to 85 ° C. warmed in the storage tank 6 is circulated and supplied into the drinking water supply pipe 7, thereby Regardless of whether or not the glass filler 4 is used, the temperature of the drinking water in the drinking water supply pipe 7 rises rapidly.

また、Sb04のステップにおいて、管内の水温が冬季モードで設定された下限値(70℃)以下ではないと判定されたときは、管内温度センサ18により水温が上限値(80℃)以上であるか否か、すなわち、飲食客に提供される飲料水(温茶)の水温が適温以上であるか否かを判定し(Sb06)、上限値(80℃)以上であると判定した場合は制御装置10が電磁バルブ9を閉鎖する(Sb07)。尚、Sb06において上限値(80℃)以上でないと判定した場合はそのときの状態を維持する。このため、冬季モードで飲料水供給装置5が運転されているときには、グラスフィラ4から抽出される飲料水の水温が冬季モードにおける最適な水温域である70℃〜80℃に維持されることになる。   If it is determined in step Sb04 that the water temperature in the pipe is not lower than the lower limit (70 ° C.) set in the winter mode, is the water temperature higher than the upper limit (80 ° C.) by the pipe temperature sensor 18? In other words, it is determined whether or not the water temperature of the drinking water (warm tea) provided to the restaurant is equal to or higher than the appropriate temperature (Sb06), and when it is determined that the temperature is equal to or higher than the upper limit (80 ° C.), the control device 10 closes the electromagnetic valve 9 (Sb07). In addition, when it determines with it not being more than an upper limit (80 degreeC) in Sb06, the state at that time is maintained. For this reason, when the drinking water supply device 5 is operated in the winter mode, the water temperature of the drinking water extracted from the grass filler 4 is maintained at 70 ° C. to 80 ° C. which is the optimum water temperature range in the winter mode. Become.

また、Sb03のステップにおいて夏季モードに設定されていると判定したときには、管内温度センサ18によって検知された飲料水供給管7内の飲料水(冷茶)の水温が、夏季モードで設定された上限値(8℃)以上であるか否か、すなわち、飲食客に提供される飲料水(温茶)の水温が適温以上であるか否かを判定し(Sb08)、飲料水の水温が上限値(8℃)以上ならば電磁バルブ9を開放する(Sb09)。   When it is determined that the summer mode is set in step Sb03, the water temperature of the drinking water (cold tea) in the drinking water supply pipe 7 detected by the pipe temperature sensor 18 is the upper limit value set in the summer mode. It is determined whether it is (8 ° C.) or higher, that is, whether the water temperature of the drinking water (warm tea) provided to the restaurant is equal to or higher than the appropriate temperature (Sb08), and the drinking water temperature is the upper limit value ( If it is 8 ° C. or higher, the electromagnetic valve 9 is opened (Sb09).

Sb09のステップにおいて電磁バルブ9が開放されると、冷却器16で冷却された1℃〜6℃の飲料水(冷茶)が飲料水供給管7内に循環供給され、これにより、複数のグラスフィラ4が使用されているか否かに関わらず、飲料水供給管7内の飲料水の水温が急速に下降することになる。   When the electromagnetic valve 9 is opened in the step of Sb09, the drinking water (cold tea) of 1 ° C. to 6 ° C. cooled by the cooler 16 is circulated and supplied into the drinking water supply pipe 7, thereby a plurality of glass fillers. Regardless of whether or not 4 is used, the temperature of the drinking water in the drinking water supply pipe 7 is rapidly lowered.

また、Sb08のステップにおいて、管内の水温が夏季モードで設定された上限値(8℃)以上ではないと判定されたときは、管内の水温が下限値(3℃)以下であるか否か、すなわち、飲食客に提供される飲料水(温茶)の水温が適温以下であるか否かを判定し(Sb10)、が下限値(3℃)以下であると判定したときは制御装置10が電磁バルブ9を閉鎖する(Sb11)。尚、Sb10において下限値(3℃)以下でないと判定した場合はそのときの状態を維持する。このため、夏季モードで飲料水供給装置5が運転されているときには、グラスフィラ4から抽出される飲料水の水温が夏季モードにおける最適な水温域である3℃〜8℃に維持されることになる。   In step Sb08, when it is determined that the water temperature in the pipe is not equal to or higher than the upper limit value (8 ° C.) set in the summer mode, whether or not the water temperature in the pipe is equal to or lower than the lower limit value (3 ° C.). That is, it is determined whether or not the temperature of the drinking water (warm tea) provided to the restaurant is not more than an appropriate temperature (Sb10), and when it is determined that is not more than the lower limit (3 ° C.), the control device 10 The electromagnetic valve 9 is closed (Sb11). In addition, when it determines with it not being below a lower limit (3 degreeC) in Sb10, the state at that time is maintained. For this reason, when the drinking water supply apparatus 5 is operated in the summer mode, the water temperature of the drinking water extracted from the grass filler 4 is maintained at 3 ° C. to 8 ° C. which is the optimum water temperature range in the summer mode. Become.

このように実施例1における飲料水供給装置5では、圧力センサ17が飲料水供給管7内の飲料水(お茶)の水圧を検知し、供給ポンプ制御処理によって、供給ポンプ8がLowモードとHighモードの2種類のモードを切り換えて駆動されるとともに、電磁バルブ制御処理によって電磁バルブ9が開閉され、飲料水供給管7内における飲料水の循環状態が切り換わることで、供給ポンプ8による飲料水供給管7内の水圧の調節に加えて、電磁バルブ9でも飲料水供給管7内の水圧を調節できるので、飲料水供給管7内の飲料水を所定の水圧域に効率的に維持することができ、多数のグラスフィラ4が同時に使用されてもグラスフィラ4から流出される飲料水(お茶)の流出量が弱まることがない。   As described above, in the drinking water supply device 5 according to the first embodiment, the pressure sensor 17 detects the water pressure of the drinking water (tea) in the drinking water supply pipe 7, and the supply pump 8 operates in the low mode and the high by the supply pump control process. It is driven by switching between two types of modes, and the electromagnetic valve 9 is opened and closed by electromagnetic valve control processing, and the drinking water circulation state in the drinking water supply pipe 7 is switched, so that the drinking water by the supply pump 8 is switched. In addition to the adjustment of the water pressure in the supply pipe 7, the water pressure in the drinking water supply pipe 7 can also be adjusted by the electromagnetic valve 9, so that the drinking water in the drinking water supply pipe 7 is efficiently maintained in a predetermined water pressure range. Even if a large number of glass fillers 4 are used at the same time, the amount of drinking water (tea) flowing out from the glass filler 4 does not weaken.

また、水圧が設定された水圧以下であるときは、水温が前記所定の水温域以上または以下であっても電磁バルブ9は閉鎖されるため、飲食客によりグラスフィラ4が使用されない状況が続く場合や、供給ポンプ8に近い上流側のグラスフィラ4ばかり使用される状況が続く場合においては、飲料水供給管7内の飲料水(お茶)が停滞し、夏季の暑い使用時期には冷茶の水温が上昇して温まりやすいとともに、冬季の寒い使用時期には温茶の水温が下降して冷めやすいが、管内温度センサ18により検知された飲料水供給管7内の水温に基づいて、上限値の水温以上または下限値の水温以下と判定したときには制御装置10が電磁バルブ9を開放することで、夏季モードでは冷却器16により冷やされたお茶が、冬季モードではプラグヒータ15により温められたお茶が飲料水供給管7内に供給されて循環することで、飲料水供給管7内全域の水温を、短時間で設定された最適な水温域に維持させることができる。   In addition, when the water pressure is equal to or lower than the set water pressure, the electromagnetic valve 9 is closed even when the water temperature is equal to or higher than the predetermined water temperature range. In the case where only the upstream glass filler 4 near the supply pump 8 is used, the drinking water (tea) in the drinking water supply pipe 7 is stagnant, and the temperature of the cold tea is hot during the hot summer season. The temperature of the hot tea falls and tends to cool down during the cold winter season, but the upper limit value is determined based on the water temperature in the drinking water supply pipe 7 detected by the pipe temperature sensor 18. When it is determined that the water temperature is equal to or higher than the water temperature or lower than the lower limit value, the control device 10 opens the electromagnetic valve 9 so that the tea cooled by the cooler 16 in the summer mode and the plug heater 1 in the winter mode. The warmed tea By circulated is supplied into the water supply pipe 7, the water temperature of the entire region in the drinking water supply pipe 7, it is possible to maintain the optimum temperature range is set in a short time.

更に、本実施例においては、管内温度センサ18が飲料水供給管7における下流側に配設され、下流側における管内の水温を検知することで、例えば供給ポンプ8に近い上流側のグラスフィラ4から流出する飲料水の水温が所定の水温域の範囲内であっても、供給ポンプ8から遠い下流側のグラスフィラ4から流出する飲料水の水温が所定の水温域の範囲外となったときに電磁バルブ処理が行われることになるため、供給ポンプ8から遠い下流側のグラスフィラ4から常に冷めた温茶やぬるい冷茶が提供されてしまうことが効果的に防止される。   Further, in the present embodiment, the pipe temperature sensor 18 is disposed on the downstream side of the drinking water supply pipe 7 and detects the water temperature in the pipe on the downstream side, so that, for example, the upstream glass filler 4 close to the supply pump 8. Even if the temperature of the drinking water flowing out from the water is within a predetermined water temperature range, the temperature of the drinking water flowing out from the downstream glass filler 4 far from the supply pump 8 is outside the predetermined water temperature range. Since the electromagnetic valve processing is performed, it is effectively prevented that warm tea or cold cold tea always cooled from the glass filler 4 on the downstream side far from the supply pump 8 is provided.

また、電磁バルブ制御処理において、冬季モードでは、管内の水温が下限値(第1の水温)である70℃以下となったときから、前記下限値よりも高い上限値(第2の水温)である80℃以上となるまで電磁バルブ9を開放させるため、飲料水供給管7内の水温が下限値である70℃まで低下するのに時間がかかることになり、これにより制御装置10が電磁バルブ9を頻繁に開閉制御しなくても済むため、制御負荷が軽減される。   Further, in the electromagnetic valve control processing, in the winter mode, when the water temperature in the pipe becomes equal to or lower than 70 ° C., which is the lower limit value (first water temperature), the upper limit value (second water temperature) higher than the lower limit value. Since the electromagnetic valve 9 is opened until the temperature reaches 80 ° C. or higher, it takes time for the water temperature in the drinking water supply pipe 7 to decrease to 70 ° C. which is the lower limit value. Since it is not necessary to frequently open and close 9, the control load is reduced.

また、夏季モードでは、管内の水温が上限値(第3の水温)である8℃以上となったときから、前記上限値よりも低い下限値(第4の水温)である3℃以下となるまで電磁バルブ9を開放させるため、飲料水供給管7内の水温が上限値である8℃まで上昇するのに時間がかかることになり、これにより制御装置10が電磁バルブ9を頻繁に開閉制御しなくても済むため、制御負荷が軽減される。   Further, in the summer mode, when the water temperature in the pipe becomes 8 ° C. or more which is the upper limit value (third water temperature), it becomes 3 ° C. or less which is the lower limit value (fourth water temperature) lower than the upper limit value. Since the electromagnetic valve 9 is opened until the water temperature in the drinking water supply pipe 7 rises to the upper limit of 8 ° C., the controller 10 frequently controls the electromagnetic valve 9 to open and close. Therefore, the control load is reduced.

次に、実施例2に係る飲料水供給装置につき、図6を参照して説明する。尚、前記実施例1と同一構成で重複する構成は省略することとする。図6は、実施例2における飲料水供給装置を示す概念図である。   Next, a drinking water supply apparatus according to Example 2 will be described with reference to FIG. In addition, suppose that the same structure as Example 1 and the overlapping structure are abbreviate | omitted. FIG. 6 is a conceptual diagram illustrating a drinking water supply apparatus according to the second embodiment.

図6に示すように、この飲料水供給装置20は、水源となる水道管(図示略)から電磁切換弁21を介して供給された飲料水(水道水)を貯留するための貯留タンク22と、貯留タンク22内の水位を検知する水位計23と、お茶の原液を貯留タンク22に供給するチューブポンプ24と、貯留タンク22内の飲料水の水温を検知するためのタンク内温度センサ25と、貯留タンク22内に貯留された飲料水を加熱するための本実施例における水温生成手段及び加熱器としてのプラグヒータ26と、上流側と下流側の両端部が貯留タンク22に連結された飲料水供給管27と、飲料水供給管27内の飲料水の水圧を検知するための圧力センサ28と、飲料水供給管27に連結された本実施例における抽出バルブとしての複数のグラスフィラ29と、貯留タンク22内の飲料水を飲料水供給管27内に供給するための供給ポンプ30と、インバータ31を介して供給ポンプ30を制御する本実施例における供給ポンプ制御手段としての制御装置32と、から構成されている。   As shown in FIG. 6, this drinking water supply device 20 includes a storage tank 22 for storing drinking water (tap water) supplied from a water pipe (not shown) serving as a water source via an electromagnetic switching valve 21. A water level meter 23 for detecting the water level in the storage tank 22, a tube pump 24 for supplying tea stock solution to the storage tank 22, and an in-tank temperature sensor 25 for detecting the temperature of the drinking water in the storage tank 22, In the present embodiment for heating the drinking water stored in the storage tank 22, the plug heater 26 as the water temperature generating means and the heater, and the beverage whose upstream and downstream ends are connected to the storage tank 22. A water supply pipe 27, a pressure sensor 28 for detecting the water pressure of the drinking water in the drinking water supply pipe 27, and a plurality of glass fillers 2 as extraction valves in this embodiment connected to the drinking water supply pipe 27 A supply pump 30 for supplying the drinking water in the storage tank 22 into the drinking water supply pipe 27, and a control device 32 as a supply pump control means in this embodiment for controlling the supply pump 30 via the inverter 31. And is composed of.

また、制御装置32は、前述した実施例1と同様に水位計23やタンク内温度センサ25などの各種センサ類からの信号に基づいて、電磁切換弁21やチューブポンプ24やプラグヒータ26や供給ポンプ30などの各種装置類の制御を行うようになっており、プラグヒータ26を作動させ、供給ポンプ30の駆動させることによって、飲料水供給管27内及び貯留タンク22内を、常に温められた飲料水(温茶)が循環されるようになっている。   The control device 32 also controls the electromagnetic switching valve 21, the tube pump 24, the plug heater 26, and the supply based on signals from various sensors such as the water level gauge 23 and the tank temperature sensor 25, as in the first embodiment. Various devices such as the pump 30 are controlled, and by operating the plug heater 26 and driving the supply pump 30, the inside of the drinking water supply pipe 27 and the inside of the storage tank 22 are always warmed. Drinking water (hot tea) is circulated.

更に、実施例1における供給ポンプ8は、LowモードとHighモードの2段階のモードを切り換えて駆動させることができるようになっていたが、実施例2における供給ポンプ30のモータ回転速度は、回転速度の低いレベル1から回転速度の速いレベル10までの10段階の回転速度を切り換えて駆動させることができる。   Furthermore, the supply pump 8 in the first embodiment can be driven by switching between the two modes of the low mode and the high mode, but the motor rotation speed of the supply pump 30 in the second embodiment is It can be driven by switching the rotation speed in 10 steps from level 1 where the speed is low to level 10 where the speed is high.

そして、制御装置32は、圧力センサ28による水圧の検知に基づいて、飲料水供給管27内の飲料水の水圧が、設定された水圧(0.3Mpa)以下ならば、供給ポンプ30のモータ回転速度のレベルを下げ、飲料水供給管27内の飲料水の水圧が、設定された水圧(0.3Mpa)以上ならば、供給ポンプ30のモータ回転速度のレベルを段階的に上げるように制御する。   Then, based on the detection of the water pressure by the pressure sensor 28, the control device 32 rotates the motor of the supply pump 30 if the drinking water pressure in the drinking water supply pipe 27 is equal to or lower than the set water pressure (0.3 Mpa). If the pressure level of the drinking water in the drinking water supply pipe 27 is lower than the set water pressure (0.3 Mpa), the level of the motor rotation speed of the supply pump 30 is controlled to increase stepwise. .

尚、飲料水供給管27に連結されたグラスフィラ29が使用されていないときに飲料水供給管27内の飲料水の水圧が、設定された水圧(0.3Mpa)になるようにレベル1のモータ回転速度が設定されるとともに、飲料水供給管27に連結されたグラスフィラ29が全て使用されているときに飲料水供給管27内の飲料水の水圧が、設定された水圧(0.3Mpa)になるようにレベル10のモータ回転速度が設定されている。   In addition, when the glass filler 29 connected to the drinking water supply pipe 27 is not used, the water pressure of the drinking water in the drinking water supply pipe 27 is set to a set water pressure (0.3 Mpa). When the motor rotation speed is set and all the glass fillers 29 connected to the drinking water supply pipe 27 are used, the water pressure of the drinking water in the drinking water supply pipe 27 is set to the set water pressure (0.3 MPa). ), The motor rotation speed of level 10 is set.

このように供給ポンプ30のモータ回転速度を複数段階で上昇または下降するように制御することで、飲料水供給管27内の飲料水の水圧を常に一定に保つことができ、多数のグラスフィラ29を同時に使用してもグラスフィラ29から流出される飲料水の水圧を一定に保つことができる。   By controlling the motor rotation speed of the supply pump 30 to increase or decrease in a plurality of stages in this way, the water pressure of the drinking water in the drinking water supply pipe 27 can always be kept constant, and a large number of glass fillers 29 can be maintained. Even if used simultaneously, the water pressure of the drinking water flowing out from the glass filler 29 can be kept constant.

However, the temperature sensor 18 may not necessarily be provided in the vicinity of the electromagnetic valve 9, for example, in the vicinity of the glass filler 4 on the most downstream side in the drinking water supply pipe 7. Alternatively, it may be disposed in the middle stream region or upstream region. Further, for example, the pipe temperature sensors 18 may be arranged at a plurality of locations, and the electromagnetic valve 9 may be controlled by determining an average value of the water temperature.
