FIG. 6 shows only the processing procedure of the processing relating to the coffee providing (extraction) operation, which is a characteristic processing in the beverage dispenser of the present embodiment, and other processing (for example, when an abnormality is detected). The processing procedure regarding the processing is omitted.

  First, the control unit 18A in the beverage dispenser of the present embodiment invalidates the beverage selection button 13 as shown in the flowchart of FIG. 6 (step S11). At this time, the control unit 18A turns off the LED lamp included in the beverage selection button 13 and notifies the user that the beverage selection button 13 is invalidated.

  Next, the control unit 18A causes the outlet door opening / closing detection sensor 12 to start detecting the opening / closing state of the outlet door 10 and causes the cup detection sensor 8 to start detecting the presence or absence of the cup 17 (step S12). Next, the control unit 18A starts recording the extraction history and the cup detection history (step S13). The control unit 18A records the time when the coffee extraction mechanism 3 last completed the extraction of coffee in the extraction history recording unit 18B as an extraction history. Further, the control unit 18A records the time at which the detection result of the cup detection sensor 8 last changed from having no cup to having a cup in the cup detection history recording unit 18C as a cup detection history.

  Next, 18 A of control parts monitor the change of the detection result of the opening / closing state of the exit door 10, and the detection result of the presence or absence of the cup 17 (step S14). If the detection result is changed (step S15: Yes), and it is determined that the outlet door closing sensor 12 detects the outlet door closing and the cup detection sensor 8 detects the presence of the cup after the change (step S15: Yes) ( Step S16: Yes), the controller 18A confirms the extraction history and the cup detection history (Step S17). On the other hand, when there is no change in the detection result (step S15: No), and when the detection result after the change does not satisfy that the outlet door is closed and the cup is present (step S16: No), the control unit 18A The process returns to the process for monitoring the change (step S14).

  When there is no extraction history (step S18: No), the control unit 18A confirming the extraction history and the cup detection history performs the coffee extraction and injection process (step S20) regardless of the cup detection history. On the other hand, when there is an extraction history (step S18: Yes), the control unit 18A confirms whether or not the cup detection sensor 8 detects the absence of a cup after the coffee extraction mechanism 3 has finally completed extraction (step S19). . When the absence of the cup is detected after the completion of the extraction (step S19: Yes), the control unit 18A performs a coffee extraction and injection process (step S20). On the other hand, if the absence of a cup has not been detected after the last extraction (step S19: No), the control unit 18A displays an error (step S21) and monitors the change in the detection result (step S14). Return to).

  When the control unit 18A starts the coffee extraction and injection process (step S20), first, as shown in the flowchart of FIG. 7, the beverage selection button 13 is activated (step S2001), and the user presses the beverage selection button 13 It waits to do (step S2002: No). At this time, the control unit 18A turns on the LED lamp included in the beverage selection button 13 to notify the user that the beverage selection button 13 has been activated.

  When the user presses the beverage selection button 13 (step S2002: Yes), the control unit 18A invalidates the beverage selection button 13 (step S2003) and causes the outlet door lock member 11 to lock the outlet door 10. (Step S2004). At this time, the control unit 18A turns off the LED lamp included in the beverage selection button 13 and notifies that the beverage selection button 13 is invalidated.

  Subsequently, the control unit 18A causes the coffee extraction mechanism 3 to extract coffee, and causes the extracted coffee to be injected into the cup 17 (step S2005). At this time, the control unit 18A turns on a predetermined operation state display lamp 14 to notify the user that coffee is being extracted.

  When the coffee extraction mechanism 3 completes the coffee extraction and the injection of the coffee into the cup 17 is completed, the control unit 18A causes the outlet door lock member 11 to unlock the outlet door 10 (step S2006). Subsequently, the control unit 18A notifies the user that the pouring of coffee into the cup 17 has been completed (step S2007). At this time, the control unit 18A turns on the predetermined operation state display lamp 14 to notify the user that the coffee injection is completed.

  Thereafter, the control unit 18A records the time when the coffee extraction by the coffee extraction mechanism 3 is completed as an extraction history (step S2008), and finishes the coffee extraction injection process.

  Control part 18A will return to the flowchart of FIG. 6 after finishing coffee extraction injection | pouring process, and will confirm the presence or absence of a raw material or a filter (step S22), and when provision of coffee can be continued (step S23: Yes) ) Returns to the process of monitoring the change in the detection result of the opening / closing state of the outlet door 10 and the detection result of the presence / absence of the cup 17 (step S14). On the other hand, if the coffee cannot be provided for some reason (for example, the raw material or the filter has run out) (step S23: No), the control unit 18A ends the process related to the coffee providing operation.

  In the beverage dispenser of the present embodiment, after the coffee extraction mechanism 3 completes the extraction of the coffee, until the cup detection sensor 8 detects the absence of the cup, the outlet door opening / closing detection sensor 12 detects the outlet door closing, Even if the cup detection sensor 8 detects the presence of a cup, the beverage selection button 13 is invalid. That is, in the beverage dispenser of the present embodiment, the user presses the beverage selection button 13 until the cup 17 containing the coffee is taken out from the cup mounting portion 7 after the coffee extraction and the injection into the cup 17 are completed. Even if pressed, the coffee extraction mechanism 3 does not extract coffee. Therefore, further coffee is poured into the cup 17 already containing coffee, and the coffee can be prevented from overflowing from the cup 17. Therefore, the beverage dispenser of this embodiment can suppress waste of raw materials and water due to the coffee extracted by the coffee extraction mechanism 3 overflowing from the cup 17 and becoming drainage.

  Furthermore, since the beverage dispenser of this embodiment does not inject further coffee into the cup 17 that already contains coffee, there is no possibility that the coffee overflows from the cup 17 or that the cup is full of coffee. For this reason, when the user takes out the cup 17, the possibility that the beverage spills and the clothes and the like become dirty is significantly reduced.

  As described above, according to the beverage dispenser of the present embodiment, it is possible to suppress waste of raw materials and water and to prevent the cup beverage from spilling and the user's clothes from becoming dirty.

  After the coffee extraction mechanism 3 completes the coffee extraction, as one of the determination conditions for causing the coffee extraction mechanism 3 to extract the coffee again, in the beverage dispenser of the present embodiment, after the coffee extraction is completed, It is set to detect no cup. However, when detecting the absence of a cup as a determination condition for causing the coffee extraction mechanism 3 to extract coffee, the present invention is not limited to this, and a predetermined time may be allowed to elapse. . By prolonging the detection time without a cup, for example, when the cup 17 is shaken due to vibration and it is detected that there is no cup, and when the cup 17 is held but placed again on the cup mounting portion 7, it is determined that there is no cup. By being detected, it is possible to prevent the coffee from being poured again into the cup 17 already containing coffee.

  After the coffee extraction is completed, if the determination condition for causing the coffee extraction mechanism 3 to extract the coffee again is that the time for detecting the absence of the cup has elapsed for a predetermined time, for example, from the presence of the cup to the absence of the cup And the time when the subsequent change to the presence of a cup is recorded as a cup detection history. Then, the determination in step S19 in the processing procedure shown in FIG. 6 is made when the time when the absence of the cup is detected for a predetermined time or more after the completion of the extraction (step S19: Yes). Extraction injection processing (step S20) is performed.

  Further, after the coffee extraction is completed, the determination condition for causing the coffee extraction mechanism 3 to extract the coffee again is that the extraction door opening / closing detection sensor 12 detects the opening of the outlet door after the coffee extraction is completed. It may be. In this case, the determination condition may be that a time during which the opening of the outlet is detected elapses over a predetermined time.

  After completing the coffee extraction, if the condition for causing the coffee extraction mechanism 3 to extract the coffee again is to detect the opening of the take-out door, it is taken instead of the cup detection history recording unit 18C shown in FIG. An exit door detection history recording unit is provided in the control means 18, and for example, the time when the exit door is closed to the exit door closed is recorded as the exit door detection history. Then, the process of step S17 in the processing procedure shown in FIG. 6 is changed to a process of confirming the extraction history and the outlet door detection history, and the determination of step S19 is finally detected after the extraction is completed and the opening of the outlet door is detected. If so (step S19: Yes), the coffee extraction and injection process (step S20) is performed.

  Furthermore, after completing the coffee extraction, the judgment condition for causing the coffee extraction mechanism 3 to extract the coffee again is to detect the opening of the outlet door and the absence of the cup after the coffee extraction is completed. May be.

  A specific example of control related to the provision (extraction) of coffee performed by the control unit 18A in the beverage dispenser of the present embodiment will be described with reference to FIGS.

  FIG. 10 is a flowchart showing a processing procedure of processing performed by the control unit in the beverage dispenser of the present embodiment. FIG. 11 is a flowchart showing a processing procedure of the coffee extraction and injection processing of FIG. FIG. 10 shows only the processing procedure of the processing related to the coffee providing (extraction) operation, which is a characteristic processing in the beverage dispenser of the present embodiment, and other processing (for example, when an abnormality is detected). The processing procedure regarding the processing is omitted.

  First, as shown in the flowchart of FIG. 10, the control unit 18A in the beverage dispenser of the present embodiment invalidates the beverage selection button 13 and the continuous extraction request button 21 (step S110). At this time, the control unit 18A turns off the LED lamps included in the beverage selection button 13 and the continuous extraction request button 21, and notifies the user that these buttons are disabled.

  Next, 18 A of control parts start the detection of the opening / closing state of the outlet door 10 by the outlet door opening / closing detection sensor 12, and the detection of the presence or absence of the cup 17 by the cup detection sensor 8 (step S12). Next, the control unit 18A starts recording the extraction history and the cup detection history (step S13). The control unit 18A records the time when the coffee extraction mechanism 3 last completed the extraction of coffee in the extraction history recording unit 18B as an extraction history. Further, the control unit 18A records the time at which the detection result of the cup detection sensor 8 last changed from having no cup to having a cup in the cup detection history recording unit 18C as a cup detection history.

  Next, 18 A of control parts monitor the change of the detection result of the opening / closing state of the exit door 10, and the detection result of the presence or absence of the cup 17 (step S14). If the detection result is changed (step S15: Yes), and the change is detected, the outlet door opening / closing detection sensor 12 detects the outlet door closing and the cup detection sensor 8 detects the presence of the cup (step). S16: Yes), the controller 18A confirms the extraction history and the cup detection history (step S17). On the other hand, when there is no change in the detection result (step S15: No), and when the detection state after the change does not satisfy that the outlet door is closed and the cup is present (step S16: No), the control unit 18A The process returns to the process for monitoring the change (step S14).

  When there is no extraction history (No at Step S18), the control unit 18A that has confirmed the extraction history and the cup detection history performs the coffee extraction and injection process (Step S200) regardless of the cup detection history. On the other hand, when there is an extraction history (step S17: Yes), the control unit 18A confirms whether or not the cup detection sensor 8 detects the absence of a cup after the coffee extraction mechanism 3 has finally completed extraction (step S19). . Then, when the absence of the cup is detected after the extraction is finally completed (step S19: Yes), the control unit 18A performs a coffee extraction and injection process (step S200). On the other hand, if the absence of a cup has not been detected after the last extraction (step S19: No), the control unit 18A displays an error (step S21) and monitors the change in the detection result (step S14). Return to).

  When starting the coffee extraction / injection process (step S200), the control unit 18A first activates the beverage selection button 13 and the continuous extraction request button 21 as shown in the flowchart of FIG. 11 (step S20001). It waits for the beverage selection button 13 to be pressed (step S20002: No). At this time, the control unit 18A turns on the LED lamps included in the beverage selection button 13 and the continuous extraction request button 21 to notify the user that these buttons have been activated.

  When the user presses the beverage selection button 13 (step S20002: Yes), the control unit 18A invalidates the beverage selection button 13 and the continuous extraction request button 21 (step S20003), and takes out to the outlet door lock member 11. The exit door 10 is locked (S20006). At this time, the control unit 18A turns off the LED lamps included in the beverage selection button 13 and the continuous extraction request button 21 and notifies that these buttons are invalidated.

  If the user presses down before disabling the continuous extraction request button 21 (step S20004: YES), the control unit 18A accepts a request for continuous extraction (step S20005), and then continues to the exit door. The exit door 10 is locked to the lock member 11. On the other hand, if the user does not press the continuous extraction request button 21 before invalidating it (step S20004: NO), the control unit 18A skips the process of step S20005 and opens the outlet door lock member 11 to the outlet. The door 10 is locked.

  After locking the outlet door 10, the control unit 18A causes the coffee extraction mechanism 3 to extract coffee, and causes the extracted coffee to be poured into the cup 17 (step S20007). At this time, the control unit 18A turns on the predetermined operation state display lamp 14 to notify the user that coffee is being extracted.

  When the coffee extraction mechanism 3 completes the coffee extraction and the coffee injection into the cup 17 is completed, the control unit 18A confirms whether a request for continuous extraction has been received. When a request for continuous extraction is received (step S20008: Yes), the control unit 18A confirms whether coffee has been extracted twice in succession. When the extraction is performed only once (step S20009: No), the control unit 18A causes the coffee extraction mechanism 3 to perform the second extraction (step S20007). On the other hand, when extracted twice (step S20009: No), the control unit 18A causes the outlet door lock member 11 to unlock the outlet door 10 (step S20010), and then the coffee is poured into the cup 17. The user is notified of the completion (step S200011). Similarly, when the request for continuous extraction is not received (step S20008: No), the control unit 18A causes the outlet door lock member 11 to unlock the outlet door 10 (step S20010) and continues. Then, the user is notified that the pouring of coffee into the cup 17 has been completed (step S20011). At this time, the control unit 18A turns on the predetermined operation state display lamp 14 to notify the user that the coffee injection is completed.

  Thereafter, the control unit 18A records the time when the coffee extraction by the coffee extraction mechanism 3 is completed as the extraction history in the extraction history recording unit 18B (step S20012), and ends the coffee extraction and injection process.

  Control part 18A will return to the flowchart of FIG. 10 after finishing coffee extraction injection | pouring process, and will confirm the presence or absence of a raw material or a filter (step S22), and when provision of coffee can be continued (step S23: Yes) ) Returns to the process of monitoring the change in the detection result of the opening / closing state of the outlet door 10 and the detection result of the presence / absence of the cup 17 (step S14). On the other hand, if the coffee cannot be provided for some reason (for example, the raw material or the filter has run out) (step S23: No), the control unit 18A ends the process related to the coffee providing operation.

  In the beverage dispenser of the present embodiment, when the user does not press the continuous extraction request button 21, the cup detection sensor 8 uses the cup detection sensor 8 after the coffee extraction mechanism 3 completes the extraction of coffee as in the beverage dispenser of the first embodiment. Until the absence of the cup is detected, even if the outlet door opening / closing detection sensor 12 detects the outlet door closing and the cup detection sensor 8 detects the presence of the cup, the beverage selection button 13 is invalid. That is, in the beverage dispenser of the present embodiment, the user presses the beverage selection button 13 until the cup 17 containing the coffee is taken out from the cup mounting portion 7 after the coffee extraction and the injection into the cup 17 are completed. Even if pressed, the coffee extraction mechanism 3 does not perform the next extraction. Therefore, it is possible to prevent the beverage from overflowing from the cup 17 by further injecting the beverage into the cup 17 already containing coffee.

  Moreover, the beverage dispenser of the present embodiment can cause the coffee extraction mechanism 3 to extract coffee twice in succession regardless of the detection result of the cup detection sensor 8 when the user presses the continuous extraction request button 21. Therefore, when a user who wants two cups of coffee places a cup on which the cup of two cups of coffee can be placed, the cup is removed after the first extraction is completed. Two cups of coffee can be poured without doing. After extracting coffee twice, until the cup detection sensor 8 detects the absence of the cup, the outlet door opening / closing detection sensor 12 detects the outlet door closing and the cup detection sensor 8 has a cup. Is detected, the beverage selection button 13 is invalid. Therefore, the beverage is further poured into the cup 17 already containing two cups of coffee, and the beverage can be prevented from overflowing from the cup 17.

  That is, the beverage dispenser of the present embodiment can not only suppress waste of raw materials and water caused by the coffee extracted by the coffee extraction mechanism 3 overflowing from the cup 17 and becoming wastewater, but also desires two cups of coffee. It is also possible to prevent a decrease in convenience for the user.

  In addition, the beverage dispenser of the present embodiment is unlikely to cause coffee to overflow from the cup 17 or to fill the cup, and when the user removes the cup 17, the beverage may spill and the clothes etc. may become dirty. Will be much lower.

  As described above, according to the beverage dispenser of the present embodiment, it is possible to suppress waste of raw materials and water and to prevent the cup beverage from spilling and the user's clothes from becoming dirty. Furthermore, according to the beverage dispenser of the present embodiment, it is possible to prevent a decrease in convenience for a user who desires two cups of coffee while suppressing waste of raw materials and water.

  In the present embodiment, after the coffee extraction mechanism 3 completes the coffee extraction, as one of the determination conditions for causing the coffee extraction mechanism 3 to extract the coffee again, the coffee extraction mechanism 3 completes the coffee extraction, It is set to detect. However, when detecting the absence of a cup as a determination condition for causing the coffee extraction mechanism 3 to extract coffee, the present invention is not limited to this, and a predetermined time may be allowed to elapse. . By prolonging the detection time without a cup, for example, when the cup 17 is shaken due to vibration and it is detected that there is no cup, and when the cup 17 is held but placed again on the cup mounting portion 7, it is determined that there is no cup. By being detected, it is possible to prevent the coffee from being poured again into the cup 17 already containing coffee.

  Further, after the coffee extraction is completed, the determination condition for causing the coffee extraction mechanism 3 to extract the coffee again is that the extraction door opening / closing detection sensor 12 detects the opening of the outlet door after the coffee extraction is completed. It may be. In this case, the determination condition may be that a time during which the opening of the outlet is detected elapses over a predetermined time.

  Furthermore, after completing the coffee extraction, the judgment condition for causing the coffee extraction mechanism 3 to extract the coffee again is to detect the opening of the outlet door and the absence of the cup after the coffee extraction is completed. May be.

  Further, the continuous extraction request button 21 may have a shape or a size different from that of the beverage selection button 13 so as to be easily distinguished from the beverage selection button 13, and is arranged at a position away from the beverage selection button 13. May be.
