Next, in a state where the second connection unit 33 is separated from the first connection unit 27 and the third connection unit 68 is connected to the first connection unit 27, an input operation is performed by the user through a predetermined input means (not shown). When a cleaning command is given to the control unit 100 as a result of the above, the control unit 100 executes the cleaning control process. In the following, it is assumed that each valve is closed and each pump is stopped.

FIG. 2 is a flowchart showing the processing contents of the cleaning control process executed by the control unit 100. In this cleaning control process, the control unit 100 performs a pre-rinse process (step S100).

FIG. 3 is a flowchart showing the processing content of the prerinsing process shown in FIG. In this prerinsing process, the control unit 100 drives the washing hot water pump 64a by sending a drive command to the washing hot water pump 64a (step S101), and starts measuring the time through the built-in clock unit (not shown). Waiting for the elapse of the preset drive time (step S102).

As a result, hot water (hot water of 85 ° C. or higher) is supplied from the hot water tank 25 to the diffusion unit 61 as washing hot water through the washing hot water supply pipe 64. The hot water supplied to the diffusion unit 61 flows inside the diffusion unit 61, is discharged from the discharge port to the cleaning supply pipe 63, and passes through the cleaning supply pipe 63. The hot water that has passed through the cleaning supply pipe 63 is used as the cleaning hot water, and is the first connecting portion 27, the liquid supply pipe 28, the mixing portion 50, the beverage delivery pipe 51, the forming portion 52, the beverage outlet passage and the nozzle portion that constitute the beverage supply path. Pass through 54.

When the drive time has elapsed (step S102: Yes), the control unit 100 sends a drive stop command to the washing hot water pump 64a to stop the washing hot water pump 64a (step S103), and the second steam supply valve 23a Is given an open command to open the second steam supply valve 23a (step S104). The control unit 100 that has opened the second steam supply valve 23a in this way starts measuring the time through the clock unit, and waits for the elapse of the preset opening time (step S105).

As a result, 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 transferred to the first connection portion 27, the liquid supply pipe 28, and the mixing portion 50. The hot water supplied in step S101 can be blown through the beverage delivery pipe 51, the forming unit 52, the beverage outlet passage and the nozzle unit 54.

When the opening time has elapsed (step S105: Yes), the control unit 100 sends a closing command to the second steam supply valve 23a to close the second steam supply valve 23a (step S106), and then the procedure is performed. Return and finish this prerinsing process.

The control unit 100 that has performed the prerinsing treatment in this way carries out the alkaline cleaning treatment (step S200).

FIG. 4 is a flowchart showing the processing contents of the alkaline cleaning treatment shown in FIG. In this alkaline cleaning process, the control unit 100 performs a hot water temperature adjusting process (step S201).

FIG. 5 is a flowchart showing the processing contents of the hot water temperature adjusting process shown in FIG. In this hot water temperature adjusting process, the control unit 100 turns off the heater 25a in a non-energized state and stops the drive (step S201a). Then, the control unit 100 drives the washing hot water pump 64a by sending a drive command to the washing hot water pump 64a (step S201b), starts measuring the time through the clock unit, and waits for the elapse of the preset adjustment time. (Step S201c). Here, the adjustment time is the time until the hot water in the hot water tank 25 becomes about half of the full water. Therefore, the amount of hot water in the hot water tank 25 is reduced to about half.

When the adjustment time has elapsed (step S201c: Yes), the control unit 100 sends a drive stop command to the washing hot water pump 64a to stop the driving of the washing hot water pump 64a (step S201d), and the water level from the float switch 25b. Waiting for signal input (step S201e).

When the water level signal is input (step S201e: Yes), the control unit 100 determines whether or not the water level (detected water level) included in the water level signal is equal to or higher than the upper limit value stored in the memory or the like (step S201f). ..

As described above, since the washing hot water pump 64a is driven to reduce the amount of hot water in the hot water tank 25 to about half of that when the water level is full, the water level included in the water level signal is less than the upper limit value. That is, when the water level is less than the upper limit value (step S201f: No), the control unit 100 gives an open command to the water supply valve 26a to open the water supply valve 26a (step S201g). As a result, water is supplied to the hot water tank 25 through the water supply pipe 26.

The control unit 100 that has opened the water supply valve 26a in this way returns to the process of step S201e, and steps S201e, step S201f, and step S201g until it is determined in step S201f that the water level is equal to or higher than the upper limit value. Repeat the process of.

When it is determined that the water level is equal to or higher than the upper limit value (step S201f: Yes), the control unit 100 gives a closing command to the water supply valve 26a to close the water supply valve 26a (step S201h), and then performs the procedure. Return and end this process.

According to this, water is supplied to the hot water tank 25 in a non-energized state of the heater 25a, and the temperature of the hot water stored in the hot water tank 25 is adjusted to an appropriate cleaning temperature range (for example, about 40 to 70 ° C.). NS.

The control unit 100 that has performed the hot water temperature adjusting process controls the switching valve 62a so that the alkaline cleaning stock solution passes through the cleaning stock solution supply pipe 62 by sending a command to the switching valve 62a (step S202), and the cleaning hot water is cleaned. A drive command is sent to the pump 64a to drive the washing hot water pump 64a (step S203).

As a result, hot water in the cleaning appropriate temperature range is supplied from the hot water tank 25 to the diffusion unit 61 as washing hot water through the washing hot water supply pipe 64. The hot water supplied to the diffusion unit 61 flows inside the diffusion unit 61, is discharged from the discharge port to the cleaning supply pipe 63, and passes through the cleaning supply pipe 63.

After that, the control unit 100 intermittently drives the cleaning stock solution supply pump 62b by intermittently sending a drive command to the cleaning stock solution supply pump 62b (step S204), starts measuring the time through the clock unit, and starts measuring the time in advance. Waiting for the elapse of the set drive time (step S205).

As a result, the alkaline cleaning stock solution is intermittently supplied to the diffusion unit 61 after passing through the cleaning stock solution supply pipe 62. The alkaline cleaning stock solution intermittently supplied to the diffusion unit 61 in this way collides with the hot water flowing inside the diffusion unit 61 and is in a state of being diffused into the hot water. As a result, the alkaline cleaning stock solution is discharged from the discharge port to the cleaning supply pipe 63 in a state of being diffused in hot water, passes through the cleaning supply pipe 63, and then the first connection portion 27 and the liquid supply pipe constituting the beverage supply path. 28, the mixing unit 50, the beverage delivery pipe 51, the forming unit 52, the beverage outlet passage and the nozzle unit 54 pass through.

When the drive time has elapsed (step S205: Yes), the control unit 100 sends a drive stop command to the cleaning stock solution supply pump 62b to stop the drive of the cleaning stock solution supply pump 62b (step S206), and at the same time, the cleaning hot water pump A drive stop command is sent to 64a to stop the drive of the washing hot water pump 64a (step S207), and an open command is given to the second steam supply valve 23a to open the second steam supply valve 23a (step S208). The control unit 100 that has opened the second steam supply valve 23a in this way starts measuring the time through the clock unit, and waits for the elapse of the preset opening time (step S209).

As a result, 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 transferred to the first connection portion 27, the liquid supply pipe 28, and the mixing portion 50. The hot water in which the alkaline cleaning stock solution supplied in steps S202 to S207 is diffused can be blown through the beverage delivery pipe 51, the forming unit 52, the beverage outlet passage and the nozzle unit 54.

When the opening time has elapsed (step S209: Yes), the control unit 100 sends a closing command to the second steam supply valve 23a to close the second steam supply valve 23a (step S210), and then the procedure is performed. Return and finish the alkaline cleaning process this time.
