As soon as the stirring blade 82 enters the cup C, the hot water supply valve V3 connected to the hot water storage tank 3 is opened for a predetermined time. When the hot water supply valve V3 is opened, the hot water in the hot water storage tank 3 is discharged toward the rotating shaft 81 of the stirring blade 82 lowered through the pipe P6 and flows down along the rotating shaft 4 and flows from the stirring blade 2 to the cup C. Supplied. When a predetermined amount of hot water is supplied into the cup C, the stirring blade 82 is rotated by the drive of the stirring motor to stir and mix to adjust the beverage. After the beverage adjustment, the elevating motor is reversed to raise the stirring blade 82 so that it comes out of the cup C. At that time, the hot water supply valve V3 is opened to discharge the hot water to the rotary shaft 81, thereby cleaning the rotary shaft 81 and the stirring blade 82. Thereafter, the cup transport mechanism 7 transfers the cup C toward the outlet 11 and provides it to the purchaser, and then the arm returns to the standby position.

  In the case of selling cold beverages, when adjusting the hot beverage described above, the hot water supply valves V2, V3 are opened to discharge a smaller amount of hot water than the amount discharged and stirred by the stirring blade 82, An ice piece unloading command is given to a solenoid that opens and closes an ice unloading door 23 provided in the ice storage section 22 of the auger type ice making machine 2, and the ice unloading door 23 is opened to be transferred to a beverage cooking position via a hose H. After supplying ice pieces to the cup C, the cup C is transferred toward the outlet 11 and provided to the purchaser. Therefore, the cup-type vending machine 100 according to this embodiment does not require a cooling water tank (which cools water from the water reservoir into cold water) that is necessary in the conventional apparatus when selling cold beverages. It is.

  Now, in the present invention, a water reservoir drain control unit 20f that performs replacement of the water stored in the water reservoir 1 via a hot water storage tank 3 that is a component of the beverage supply device is provided. The replacement control of the water stored in the water reservoir 1 will be described with reference to the time chart shown in FIG. In this embodiment, the replacement control of the water stored in the water reservoir 1 by the water reservoir drain control unit 20f is performed at night when there are few sales opportunities, for example, at midnight. In this case, the sales control unit 20a Displays the characters “sale discontinued” on the display device 22 and prohibits the acceptance of money into the money insertion unit 23. The time t0 on the horizontal axis in FIG. 3 indicates midnight, and “ON "Indicates operation" and "OFF" indicates non-operation. In FIG. 3, water and hot water are stored in the water reservoir 1 and the hot water tank 3 up to the upper limit water level at time t0, and the water stored in the hot water tank 3 is heated to a desired temperature (for example, 94 to 97 ° C.). The figure shows a case where a predetermined amount of ice pieces are stored in the ice storage chamber 22 of the auger type ice making machine 2, and when the drainage from the hot water storage tank 3 is drained via the hot water supply valves V2 and V3, The case where the coffee brewer 13 is washed by drainage from the valve V2 and the stirring blade 82 of the beverage stirring device 8 is washed by drainage from the hot water supply valve V3 is illustrated. That is, at time t0, the water supply sensor S1 that detects the upper limit water level of the water reservoir 1 is OFF and the water supply valve V1 is OFF, the water supply start sensor S3 that detects the lower limit water level of the hot water storage tank 3 is OFF, and the upper limit water level is set. The water supply stop sensor S4 to be detected is on and the water pump PMP is off, the compressor of the auger type ice making machine 2 is off, and the heater 31 of the hot water storage tank 3 is off.

  At time t0 in such a state, the water supply valve V1, the compressor of the auger type ice making machine 2 and the heater 31 of the hot water storage tank 3 are forcibly turned off and the coffee brewer 13 and the beverage agitator 8 are operated in parallel. That is, in the coffee brewer 13, when the time t0 is reached, the extraction container is lowered to open the upper end opening of the extraction container. At the time t1 when the upper end opening of the extraction container is opened, the hot water supply valve V2 of the hot water storage tank 3 is opened to supply a predetermined amount (for example, 200 ml) of hot water. In the coffee brewer 13, when a predetermined amount of hot water is supplied from the hot water storage tank 3 through the pipe P5, the upper end opening of the extraction container is closed by the valve mechanism, and then air is supplied from the lower air inlet of the extraction container. And stir the warm water. The inside of the extraction container is washed by the stirring of the warm water. Next, when the stirring is completed, the cleaning liquid that has cleaned the inside of the extraction container is discharged to the beverage cooking position via the pipe P7. In this case, the liquid discharged through the pipe P7 falls into the tray main body 91 of the powder tray 9 and flows into the cup housing 92, and the waste liquid is discharged through the waste liquid port 92a and the waste liquid tube 92b of the cup housing 92. It is collected in the bucket 10.

  On the other hand, in the beverage agitator 8, when the time t0 is reached, the elevating motor that moves the rotating blade 82 up and down is driven to lower the rotating blade 82. At the time t3 when the rotary blade 82 is lowered, the hot water supply valve V3 of the hot water storage tank 3 is opened to supply hot water. In this case, in the beverage stirring device 8, the hot water supplied from the hot water storage tank 3 via the pipe P <b> 6 is discharged to the rotating shaft 81 of the stirring blade 82, and thus is discharged to the rotating shaft 81. The warm water flows down through the stirring blade 8 via the rotating shaft 81. The rotating shaft 81 and the stirring blade 8 are washed by the hot water flowing down the rotating shaft 81 and the stirring blade 8. As described above, the washing water that has washed the rotating shaft 81 and the stirring blade 8 flows down to the tray main body 91 of the powder tray 9 and is collected in the waste liquid bucket 10 through the waste liquid port 92a and the waste liquid tube 92b of the cup housing 92. The In addition, the hot water supply valve V3 of the hot water storage tank 3 is opened until the time t7 when the drainage of the water stored in the water reservoir 1 is completed, as will be described later.

  As described above, when the hot water supply valve V2 of the hot water storage tank 3 is opened and the hot water is discharged, the water supply stop sensor S4 that detects the upper limit water level of the hot water storage tank 3 by lowering the level of the hot water stored in the hot water storage tank 3 is provided. The water pump PMP is forcibly driven at a time point t2 when it is turned off from on. As a result, the water stored in the water reservoir 1 is supplied to the hot water storage tank 3 via the pipe P4, so that the water level of the water reservoir 1 gradually decreases. The flow rates of the water pump PMP and the hot water supply valves V2 and V3 of the hot water storage tank 3 are determined as (water pump PMP)> (hot water supply valves V2 and V3 of the hot water storage tank 3) in this embodiment. When the water level 3 rises and the water supply stop sensor S4 is turned on, the driving of the water pump PMP is temporarily stopped (time t4). However, since the hot water supply valve V3 of the hot water storage tank 3 is opened and the hot water in the hot water storage tank 3 continues to be discharged, the water pump PMP at the time t5 when the water level of the hot water storage tank 3 falls again and the water supply stop sensor S4 is turned off from on. When the water level of the hot water storage tank 3 rises and the water supply stop sensor S4 is turned on, the operation of temporarily stopping the water pump PMP is repeated (indicated by the dotted line in the figure). In this way, the water supply valve is driven after a predetermined time T has elapsed (time t7) from time t6 when the abnormality detection sensor S2 that detects the lower limit water level of the water reservoir 1 is turned on by driving the water pump PMP and the lower limit water level of the water reservoir 1 is turned on. V1 is opened to supply water from the water pipe to the water reservoir 1.

  Here, during the predetermined time T, water remains in the water reservoir 1 and the pipes P1, P2, and P3 even when the abnormality detection sensor S2 that detects the lower limit water level of the water reservoir 1 is turned on. This is the time until water is supplied to the hot water storage tank 3 by the water pump PMP. Therefore, when the water supply valve V1 is opened to supply water from the water pipe to the water reservoir 1, all the water in the water reservoir 1 and the pipes P1, P2, P3 is drained and replaced.

  Although the water level of the hot water storage tank 3 at the time point t7 is normal, FIG. 3 shows a case where the upper limit water level has not been reached at the time point t7. In this case, after the water pump PMP is stopped once at the time point t7, The driving is resumed when the abnormality detection sensor S2 is turned off, and the driving is continued until the water supply stop sensor S4 is turned on.

  Further, since the hot water supply valve V3 of the hot water storage tank 3 is closed at the time point 7, the beverage agitating device 8 raises the rotary blades 82 by driving the lift motor for moving the rotary blades 82 up and down in reverse. At time t7, the heater 31 is turned on on condition that the water supply start sensor S3 for detecting the lower limit water level of the hot water storage tank 3 is turned off, and the abnormality detection sensor S2 for detecting the lower limit water level of the water reservoir 1 is turned off. And the compressor of the auger ice making machine 2 is driven on condition that the ice making start switch for detecting that the ice storage amount in the ice storage chamber of the auger ice making machine 2 is lowered to the ice storage amount lower limit position is ON. Begin ice making.

  In FIG. 3, the water supply start sensor S3 that detects the lower limit water level of the hot water storage tank 3 remains off and does not change to on. This is because, in this embodiment, the capacity of the water reservoir 1 and the hot water storage tank 3 is determined as water reservoir 1 <hot water storage tank 3, so that when the water in the water reservoir 1 is replaced, This is because all the hot water is not drained and emptied. When the hot water in the hot water storage tank 3 is drained and replaced simultaneously with the replacement of the water in the water reservoir 1, the hot water supply valves V2 and V3 of the hot water storage tank 3 are turned off after the water pump PMP is stopped after time t7. The above-described operation of opening and draining is repeated until the water supply start sensor S3 is turned on, and then the water pump PMP is driven to supply water from the water reservoir 1 to the hot water storage tank 3. It is.
