  The electric pump 30 is a well-known electric water pump in which an internal rotor such as a vane pump is rotated by a motor, and the drinking water WA from the communication pipes 4 and 5 is circulated to the beverage storage section 20 side. The rotor of the electric pump 30 is provided with a notch so as to allow natural circulation of the drinking water WA by gravity even when the rotor is not rotating. In addition, the electric pump 30 includes a detection unit 31 that detects whether or not the drinking water WA in the electric pump 30 is distributed. The detection means 31 comprises a known ammeter, and detects the presence or absence of the circulation of the drinking water WA in the electric pump 30 based on the difference in the drive current of the electric pump 30. That is, when the drinking water WA is circulating in the electric pump 30, a predetermined load is generated in the motor that rotates the rotor, and the current value of the driving current of the electric pump 30 is greater than or equal to a predetermined magnitude. When the drinking water WA is not circulating in the pump 30, since the current value of the drive current is less than a predetermined magnitude, it is possible to detect the presence or absence of the drinking water WA in the electric motor 30.

  The discharge valve 40 is a well-known flow control valve that opens and closes the flow path by the rotation of the spindle, and is fixed to the side surface portion of the beverage dispenser body 1 with its discharge port facing downward. Moreover, the mounting base 1b which mounts the cup for drinks under the discharge valve 40 of the drink dispenser main body 1 is provided. Furthermore, when the discharge valve 40 is opened, the rotor of the electric pump 30 is configured to rotate.

  As shown in FIG. 4, the control unit 50 is composed of a microcomputer and is connected to the detection means 31 of the electric pump 30 and the electromagnetic valves 6 and 7. The control unit 50 is configured to open one of the electromagnetic valves 6 and 7 and close the other.

  In the beverage dispenser configured as described above, as shown in FIG. 1, the beverage container 10 in which the drinking water WA is accommodated in each beverage inlet 2, 3 on the upper portion of the beverage dispenser main body 1 has its opening 10 a. Can be mounted facing downward. Since the drinking water WA in each beverage container 10 is circulated to the electromagnetic valves 6 and 7 through the communication pipes 4 and 5 and either one of the electromagnetic valves 6 or 7 is opened by the control unit 50, either Drinking water WA in one beverage container 10 circulates in the electric pump 30. For example, when the first electromagnetic valve 6 is opened and the second electromagnetic valve 7 is closed, the drinking water WA in the beverage container 10 connected to the beverage inlet 2 flows to the electric pump 30, and the electric pump 30. The drinking water WA flows from the notch provided in the rotor to the beverage storage section 20 side, and the drinking water WA flows into the tank 21 until the communication pipe 24 is immersed in the drinking water WA. .

  When the discharge valve 40 is opened in this state, the rotor of the electric pump 30 is rotated by opening the discharge valve 40, and the drinking water WA is circulated to the beverage storage unit 20 side by the electric pump 30. Drinking water WA is discharged from the discharge valve 40.

  As shown in FIG. 2, when there is no drinking water WA in the beverage container 10 attached to the beverage inlet 2 and the drinking water WA no longer circulates in the electric pump 30, the load on the motor of the electric pump 30 is reduced. The current value of the drive current decreases. Therefore, the flow of the drinking water WA in the electric pump 30 is not detected by the detection means 31, and the first electromagnetic valve 6 is closed and the second electromagnetic valve 7 is opened by the control unit 50. The operation of the control unit 50 at this time will be described with reference to the flowchart shown in FIG. 5. When the control unit 50 opens the first electromagnetic valve 6 and closes the second electromagnetic valve 7, the detection means 31. When the flow of the drinking water WA in the electric pump 30 is no longer detected (S1), the opened first electromagnetic valve 6 is closed and the closed second electromagnetic valve 7 is opened (S2). Thereby, the drinking water WA of the beverage container 10 attached to the beverage inlet 3 is circulated on the electric pump 30 side.

  While the drinking water WA of the beverage container 10 attached to the beverage inlet 3 is being circulated through the beverage reservoir 20, the beverage container 10 at the beverage inlet 2 can be replaced with a new beverage container 10. Therefore, when the drinking water WA in the beverage container 10 attached to the beverage injection port 3 runs out next, the control unit 50 closes the second electromagnetic valve 7 and the first electromagnetic valve 6 to open the beverage injection. Drinking water WA in the beverage container 10 connected to the inlet 2 flows to the electric pump 30 side. That is, when there is no drinking water WA in one of the beverage containers 10, the drinking water WA in the other beverage container 10 is circulated.

Here, for example, when the drinking water WA of each beverage container 10 is lost because the beverage container 10 is not replaced, the water level in the tank 21 is lowered and the drinking water WA does not circulate through the communication pipe 24. The heater 22 is exposed from the drinking water WA. At this time, the beverage reservoir 20 becomes lighter, the spring member 26 raises the base portion 21a of the beverage reservoir 20 from the bottom surface 1a in the beverage dispenser body 1, and the switch 27 cuts off the power supply to the heater 22. It has become. That is, even if the beverage container 10 is forgotten to be replaced and the water level of the beverage reservoir 20 is lowered, the heater 22 can be prevented from being deteriorated due to emptying.

  Thus, according to the beverage dispenser of the present embodiment, a plurality (two in the present embodiment) of beverage containers 10 are detachably mounted on the beverage dispenser 1 at the beverage inlets 2 and 3, respectively. 10 is provided with electromagnetic valves 6 and 7 that can respectively open and close the flow path of the drinking water WA from the beverage reservoir 20 to the side of the beverage storage section 20, and when one of the electromagnetic valves 6 and 7 is opened, the other is closed. Since the drinking water WA in each beverage container 10 is lost one side at a time, when the drinking water WA in either one of the beverage containers 10 is exhausted, the opening and closing of the electromagnetic valves 6 and 7 are switched respectively. By allowing the drinking water WA in the beverage container 10 to circulate, it will not become unusable even until the new beverage container 10 is mounted.

  Moreover, since the drinking water WA was supplied to the beverage storage part 20 from the other beverage container 10 when exchanging the beverage container 10 from which the drinking water WA has disappeared, the operation of replacing the beverage container 10 is performed. Even if there is no urgent need, the beverage dispenser will not be immediately disabled. Therefore, it is possible to use a small capacity for each beverage container, and the replacement work of the beverage container 10 becomes easy.

  In the present embodiment, two beverage containers 10 are mounted, but three or more beverage containers 10 may be mounted. Thereby, it becomes possible to make the capacity | capacitance of each drink container 10 still smaller, and the replacement | exchange operation | work of the drink container 10 becomes easier.

  Furthermore, when the presence or absence of the drinking water WA in each beverage container 10 is detected by the detection means 31 provided in the electric pump 30, and the distribution of the drinking water WA in the electric pump 30 is no longer detected by the detection means 31, the control unit 50 Since the opening and closing of the electromagnetic valves 6 and 7 are switched by the above, the drinking water WA in the other beverage container 10 automatically circulates when the drinking water WA in one beverage container 10 runs out, and the beverage dispenser cannot be used. Can be surely prevented.

  Moreover, since the detection means 31 detects the presence or absence of the drinking water WA in each beverage container 10 based on the difference in the drive current of the electric pump 30, the drinking water is provided like a flow meter provided in the flow path of the drinking water WA. There is no need to newly provide a device that directly contacts the WA, and the taste of the drinking water WA is not deteriorated by the means for detecting the distribution of the drinking water WA.

  In addition, since the drink container 10 can accommodate the drink water WA and the screw part 10b is provided in the outer peripheral side of the opening part 10a, the commercially available PET bottle containing the drink water WA may be used. It is also possible to use it. Since many PET bottles containing drinking water WA are distributed in the market, it is easy to obtain, and since there is a wide range of capacity selection, it is easier to attach the beverage container 10 to the beverage dispenser body. It is also possible to select a smaller one.

  Furthermore, in this embodiment, although what heated the drinking water WA in the beverage storage part 20 with the heater 22 was shown, it uses the cooler, such as an evaporator, instead of the heater 22, and drinks in the beverage storage part 20 The water WA may be cooled. Moreover, you may make it cool the drinking water WA of the other beverage storage part 20 while heating the drinking water WA of some drink storage parts 20 using two or more drink storage parts 20. FIG.

  In addition, as shown in FIG. 6, in order to show the open / close state of each electromagnetic valve 6 and 7, it is also possible to provide the 1st LED60 and the 2nd LED61 as a display means. That is, the LEDs 60 and 70 are connected to the control unit 50. When the first electromagnetic valve 6 is opened, the first LED 60 is turned on, and when the first electromagnetic valve 6 is closed, the first LED 60 is not turned on. The second LED 61 is turned on when the second electromagnetic valve 7 is opened, and the second LED 61 is not turned on when the second electromagnetic valve 7 is closed. .

  The operation of the control unit 50 at this time will be described with reference to the flowchart shown in FIG. 7. For example, the control unit 50 opens the first electromagnetic valve 6, closes the second electromagnetic valve 7, and sets the first LED 60. In the case where the second LED is not lit while being lit, when the flow of the drinking water WA in the electric pump 30 is not detected by the detection means 31 (S10), the opened first electromagnetic valve 6 is closed, The closed second electromagnetic valve 7 is opened (S11). At this time, the first LED 60 is turned off and the second LED is turned on (S12).

  Thus, when the open / close state of each electromagnetic valve 6, 7 is indicated by each LED 60, 61, the open / close state of each electromagnetic valve 6, 7 is ensured even when the inside of each beverage container 10 cannot be visually observed. Can be distinguished.

  In addition, as shown in FIG. 8, in order to show the presence or absence of the drinking water WA of each drink container 10, it is also possible to provide 3rd LED62 and 4th LED63 as a display means. That is, each LED 62, 63 is provided corresponding to each beverage container 10 and is connected to the control unit 50. When the opening and closing of each solenoid valve 6, 7 is switched, drinking water WA is stored immediately before that. It is comprised so that the LED by the side of the drink container 10 supplied to the part 20 may be lighted.

  The operation of the control unit 50 at this time will be described with reference to the flowchart shown in FIG. 9. For example, the control unit 50 opens the first electromagnetic valve 6 and closes the second electromagnetic valve 7, and the third LED 62 The fourth LED 63 is configured to indicate the presence or absence of the drinking water WA in the beverage container 10 on the second electromagnetic valve 7 side, and configured to indicate the presence or absence of the drinking water WA in the beverage container 10 on the first electromagnetic valve 6 side. When the flow of the drinking water WA in the electric pump 30 is no longer detected by the detection means 31 (S20), the first electromagnetic valve 6 that has been opened is closed and the second electromagnetic valve that has been closed 7 is released (S21). At this time, the third LED 62 indicating the presence or absence of the drinking water WA in the beverage container 10 on the first electromagnetic valve 6 side is turned on (S22). The third LED 62 and the fourth LED 63 are configured to be turned off by operating the control unit 50 from the outside, and are operated by an operator who replaces the beverage container 10 with a new beverage container 10.

  Thus, if the presence or absence of the drinking water WA in each beverage container 10 is indicated by the LEDs 62 and 63, the presence or absence of the drinking water WA in each beverage container 10 can be determined even when the inside of each beverage container 10 cannot be visually observed. Can be reliably identified.

  Furthermore, as shown in FIG. 10, it is also possible to provide a fifth LED 64 as a display means that lights up when both of the drinking waters WA in each beverage container 10 are exhausted. The fifth LED 64 is connected to the control unit 50 and is configured to be lit when the drinking water WA in each beverage container 10 runs out, that is, when both the LEDs 62 and 63 are lit.

  The operation of the control unit 50 at this time will be described with reference to the flowchart shown in FIG. 11. For example, the control unit 50 opens the first electromagnetic valve 6 and closes the second electromagnetic valve 7, and the third LED 62 The fourth LED 63 is configured to indicate the presence or absence of the drinking water WA in the beverage container 10 on the second electromagnetic valve 7 side, and configured to indicate the presence or absence of the drinking water WA in the beverage container 10 on the first electromagnetic valve 6 side. If the flow of the drinking water WA in the electric pump 30 is no longer detected by the detection means 31 (S30), the first electromagnetic valve 6 that has been opened is closed and the second electromagnetic valve that has been closed 7 is released (S31). At this time, the third LED indicating the presence or absence of the drinking water WA in the beverage container 10 on the first electromagnetic valve 6 side is turned on (S32).

  In this state, when the flow of the drinking water WA in the electric pump 30 is not detected again by the detection means 31 without replacing the beverage container 10 (S33), the opened second electromagnetic valve 7 is closed. At the same time, the closed first electromagnetic valve 6 is opened (S34). At this time, the fourth LED indicating the presence or absence of the drinking water WA in the beverage container 10 on the second electromagnetic valve 7 side is turned on (S34). Thereby, since each LED62, 63 lights up (S35), the 5th LED64 which shows that the drinking water WA of each beverage container 10 was lost for both uses is lighted (S36).

  As described above, when the fifth LED 64 indicates that both of the drinking water WA in each beverage container 10 has disappeared, the beverage dispenser becomes unusable even when the inside of each beverage container 10 cannot be visually observed. Can be reliably identified.
