  In the forming unit 52, the amount of foaming of the milk drink is increased and the foamed foam comes into contact with the wall surface or the like. The foamed milk beverage passes through the beverage outlet passage and is delivered to the nozzle portion 54, and is discharged from the nozzle portion 54 to the cup C, whereby the milk beverage is supplied.

  Next, as shown in FIG. 2, in a state where the second connection portion 33 is disconnected from the first connection portion 26 and the third connection portion 68 is connected to the first connection portion 26, a predetermined input means ( When a cleaning command is given to the control unit 100 as a result of performing an input operation through (not shown), the control unit 100 performs a cleaning control process. In the following, it is assumed that each valve is closed and each pump is stopped.

  FIG. 7 is a flowchart showing the processing content of the cleaning control process performed by the control unit 100. In this cleaning control process, the control unit 100 performs a pre-rinse process (step S100).

  FIG. 8 is a flowchart showing the processing contents of the pre-rinsing process shown in FIG. In this pre-rinsing process, the control unit 100 sends a drive command to the cleaning water pump 65a (step S101), starts measuring time through a built-in clock unit (not shown), and waits for elapse of a preset drive time. (Step S102).

  As a result, hot water is supplied from the hot water tank 25 to the mixing container 61 through the cleaning hot water supply pipe 65 as cleaning hot water. As described above, since the other end side of the cleaning water supply pipe 65 is branched into two, a part of the hot water is discharged upward from the discharge port 611. In addition, as described above, the washing hot water supply pipe 65 communicating with the upper hot water supply port 612 extends in the substantially tangential direction of the side portion 61a of the mixing container 61 at the upper hot water supply port 612. It is discharged from the upper hot water supply port 612 and passes spirally downward along the inner wall surface of the side portion 61 a of the mixing container 61.

  When the drive time has elapsed (step S102: Yes), the control unit 100 sends a drive stop command to the hot water pump 65a (step S103), starts measuring time through the clock unit, and sets a standby time that is set in advance. (Step S104). Here, the waiting time is a time provided for the hot water sent out by the washing water pump 65a to reach the mixing container 61 with certainty.

  When the standby time has elapsed (step S104: Yes), the control unit 100 sends a driving command to the cleaning liquid pump 64a (step S105), starts measuring time through the clock unit, and elapses of a preset driving time. The process waits (step S106). Thereby, the hot water in the mixing container 61 is used as washing hot water, the first connection part 26, the liquid supply pipe 27, the mixing part 50, the beverage delivery pipe 51, the forming part 52, and the beverage derivation constituting the beverage supply path from the cleaning liquid supply pipe 64. It passes through the passage and nozzle part 54.

  When the drive time has elapsed (step S106: Yes), the control unit 100 sends a drive stop command to the cleaning liquid supply pump and gives an open command to the second steam supply valve 23a (step S107, step S108). Thus, the control part 100 which gave the opening instruction | command to the 2nd steam supply valve 23a starts time measurement through a timepiece part, and waits for progress of the preset opening time (step S109).

  Accordingly, the second steam supply valve 23a is opened until the opening time elapses, so that the pressurized steam that has passed through the second steam supply pipe 23 is converted into the first connection part 26, the liquid supply pipe 27, the mixing part 50, The hot water supplied in step S105 can be blown through the beverage delivery pipe 51, the forming portion 52, the beverage outlet passage and the nozzle portion 54.

  When the opening time has elapsed (step S109: Yes), the control unit 100 sends a close command to the second steam supply valve 23a (step S110), and then returns the procedure to end the current pre-rinsing process.

  Thus, the control part 100 which implemented the pre-rinsing process performs an alkali washing process (step S200).

  FIG. 9 is a flowchart showing the contents of the alkali cleaning process shown in FIG. In this alkali cleaning process, the control unit 100 sends a drive command to the first cleaning stock solution supply pump 62a (step S201), starts measuring time through the clock unit, and waits for elapse of a preset driving time ( Step S202).

  When the drive time has elapsed (step S202: Yes), the control unit 100 sends a drive stop command to the first cleaning stock solution supply pump 62a (step S203).

  As a result, the first cleaning stock solution supply pump 62a is driven for the above driving time, and the alkaline cleaning stock solution stored in the first cleaning stock solution storage unit 66 is supplied to the mixing container 61 by a predetermined amount. The alkaline cleaning stock solution supplied to the mixing container 61 is stored in the lower part of the mixing container 61.

  Then, the control unit 100 sends a drive command to the hot water pump 65a (step S204), starts measuring time through the clock unit, and waits for elapse of a preset drive time (step S205). Thus, hot water is supplied from the hot water tank 25 to the mixing container 61 as cleaning hot water through the cleaning hot water supply pipe 65. As described above, the other end of the cleaning water supply pipe 65 is branched into two, a part of the hot water is discharged upward from the discharge port 611, and the remaining hot water is mixed from the upper hot water supply port 612. Since it passes spirally downward along the inner wall surface of the side portion 61a of the container 61, the already stored alkaline cleaning stock solution and hot water (cleaning hot water) can be satisfactorily stirred. A cleaning liquid can be generated.

  When the drive time has elapsed (step S205: Yes), the control unit 100 sends a drive stop command to the hot water pump 65a (step S206), starts measuring the time through the clock unit, and sets a preset standby time. (Step S207). This standby time is a time provided for the hot water sent out by the washing hot water pump 65a to reach the mixing container 61 reliably, as in the pre-rinsing process described above.

  When the standby time has elapsed (step S207: Yes), the control unit 100 performs an alkaline cleaning liquid supply process (step S208).

  FIG. 10 is a flowchart showing the processing contents of the alkaline cleaning liquid supply processing shown in FIG. In this alkaline cleaning liquid supply process, the control unit 100 sends a drive command to the cleaning liquid pump 64a (step S208a), starts measuring time through the clock unit, and waits for elapse of a preset set time (step S208b). .

  Thereby, the alkaline cleaning liquid of the mixing container 61 is supplied from the cleaning liquid supply pipe 64 to the first connection part 26, the liquid supply pipe 27, the mixing part 50, the beverage delivery pipe 51, the forming part 52, the beverage outlet passage and the nozzle. Pass through part 54.

  When the set time has elapsed (step S208b: Yes), the control unit 100 sends a drive stop command to the cleaning liquid supply pump (step S208c), starts measuring time through the clock unit, and sets a preset drive stop time. (Step S208d).

  According to this, it is possible to perform an intermittent drive in which the cleaning liquid supply pump is driven for the set time and the cleaning liquid supply pump is stopped during the drive stop time.

  When the drive stop time has elapsed (step S208d: Yes), the control unit 100 sends an open command to the second steam supply valve 23a (step S208e), starts time measurement through the clock unit, and is set in advance. It waits for the elapsed open time (step S208f).

  When the opening time has elapsed (step S208f: Yes), the control unit 100 sends a close command to the second steam supply valve 23a (step S208g), and the cleaning liquid pump 64a is driven a predetermined number of times in advance. It is confirmed whether or not n times have been reached (step S208h).

  When the number of driving times of the cleaning liquid pump 64a has not reached n times (step S208h: No), the control unit 100 repeats the processes of steps S208a to S208g described above.

  On the other hand, when the number of times of driving the cleaning liquid pump 64a has reached n (step S208h: Yes), the control unit 100 sends a driving command to the cleaning liquid pump 64a (step S208i), and then returns the procedure. This alkaline cleaning liquid supply process is terminated.

  The controller 100 that has performed the alkali cleaning liquid supply process in this way, when the time measured through the clock unit after performing Step S208i has passed a preset driving time (Step S209: Yes), the mixing container 61 Assuming that all of the alkaline cleaning liquid inside is supplied, a drive stop command is sent to the cleaning liquid pump 64a (step S210).

  Then, the control unit 100 gives an opening command to the second steam supply valve 23a (step S211), starts time measurement through the clock unit, and waits for elapse of a preset opening time (step S212). Thereby, the alkali cleaning liquid supplied in the above procedure can be blown.

  When the opening time has elapsed (step S212: Yes), the control unit 100 sends a close command to the second steam supply valve 23a (step S213), and then returns the procedure to end the current alkali cleaning process. .

  The control unit 100 that has performed the alkali cleaning process in this manner performs an alkali cleaning rinse process (step S300).

  FIG. 11 is a flowchart showing the processing contents of the alkaline cleaning rinsing processing shown in FIG. In this alkaline cleaning rinsing process, the control unit 100 sends a drive command to the hot water pump 65a (step S301), starts measuring time through the clock unit, and waits for elapse of a preset driving time (step S302). ).

  As a result, hot water is supplied from the hot water tank 25 to the mixing container 61 through the cleaning hot water supply pipe 65 as cleaning hot water. As described above, since the other end side of the cleaning water supply pipe 65 is branched into two, a part of the hot water is discharged upward from the discharge port 611. In addition, as described above, the washing hot water supply pipe 65 communicating with the upper hot water supply port 612 extends in the substantially tangential direction of the side portion 61a of the mixing container 61 at the upper hot water supply port 612. It is discharged from the upper hot water supply port 612 and passes spirally downward along the inner wall surface of the side portion 61 a of the mixing container 61.

  When the drive time has elapsed (step S302: Yes), the control unit 100 sends a drive stop command to the hot water pump 65a (step S303), starts measuring the time through the clock unit, and sets a preset standby time. (Step S304). Here, the waiting time is a time provided for the hot water sent out by the washing water pump 65a to reach the mixing container 61 with certainty.

  When the standby time has elapsed (step S304: Yes), the control unit 100 sends a driving command to the cleaning liquid pump 64a (step S305), starts measuring time through the clock unit, and elapses of a preset driving time. Waiting (step S306). Thereby, the hot water in the mixing container 61 is used as washing hot water, the first connection part 26, the liquid supply pipe 27, the mixing part 50, the beverage delivery pipe 51, the forming part 52, and the beverage derivation constituting the beverage supply path from the cleaning liquid supply pipe 64. It passes through the passage and nozzle part 54.
