As a result, if there is no expected carbonic acid content, it is considered to discard the carbonated water and regenerate carbonated water, but unnecessary waste will occur. In addition, it has been considered that too much carbonated water is added to the carbonated water directly to contain carbonic acid, but carbonic acid cannot be contained efficiently, and it is difficult to return to the desired carbonic acid content. In addition, it is generally necessary to perform regular sterilization in a beverage supply device, but a sterilization method that efficiently utilizes the device configuration of the carbonization tank has not been proposed. In this way, there is still room for improvement in the technique used to optimize the operation of the carbonization tank.

In addition, carbonic acid is extracted from carbonated water by heating carbonated water. However, as mentioned above, because carbonated water can be fed into the carbonization tank through the carbonated water outlet and branch pipelines, the carbonated water can be fed from the water supply path again, so the efficiency can be improved again Contains carbonic acid.

One aspect is best if it includes a cooler for cooling the carbonated water in the carbonization tank.

As shown in Figure 1, the beverage supply device of this embodiment mainly includes a water supply source 10, a cold water tank 20 for cooling and storing water 50 supplied from the water supply source 10, and a cold water tank The water 50 supplied to the barrel 20 is added with carbon dioxide gas to produce carbonated water in the carbonization tank barrel 30, and a part of the water 50 in the cold water tank barrel 20 is taken out and heated and stored in the warm water tank barrel 40.

The water supply source 10 supplies water 50 such as mineral water to the cold water tank 20. In this embodiment, although the water supply source 10 is shown as a container for storing mineral water, the water supply source 10 may be a water channel or the like, and the water 50 can be supplied to the cold water tank 20 is not particularly limited. In this embodiment, the water supply source 10 is arranged above the cold water tank barrel 20, and the water supply part 11 provided at the bottom of the water supply source 10 is connected to the cold water tank barrel 20. In addition, the water 50 is supplied from the water supply source 10 to the cold water tank 20 by the permeated water supply unit 11.

The cold water tank barrel 20 is a cooler that uses the water 50 in the cold water tank barrel 20 as a cooler, is arranged in a spiral shape on its outer surface, and has a cooling coil 21 that circulates the refrigerant inside by opening the solenoid valve 21a. By cooling the water 50 supplied from the water supply source 10 by the cooling coil 21, The cold water tank 20 stores the cooled water 50. In addition, a check valve 21b is provided in a part of the flow path through which the used refrigerant flows to prevent the used refrigerant from flowing backward. In addition, the cold water tank 20 is provided with a temperature sensor (not shown), and the temperature of the water 50 is detected by the temperature sensor. The cold water tank bucket 20 has a water delivery path 22 that sends water 50 as beverage water from the cold water tank bucket 20. By opening the solenoid valve 22a provided in the water delivery path 22, the water delivery path 22 can be passed from the cold water tank. Water 50 is provided in the bucket 20. In addition, the cold water tank barrel 20 has a water supply path 24 for supplying water 50 to the carbonization tank barrel 30, and the water 50 is carbonized from the cold water tank barrel 20 by the operation of the high-pressure pump 24b provided in the water supply path 24 The tank 30 is supplied. Moreover, in the carbonization tank barrel 30 side of the high-pressure pump 24b in the water supply path 24, a check valve 24c that prevents the water 50 and carbon dioxide from flowing back to the cold water tank barrel 20 side is inserted.

The carbonization tank barrel 30 is connected to the carbon dioxide gas high-pressure vessel 31 through the carbon dioxide gas supply path 32. By opening the solenoid valve 32a inserted between the carbon dioxide supply path 32, carbon dioxide is supplied from the carbon dioxide high-pressure vessel 31 to the carbonization tank 30, and the pressure is adjusted by a pressure regulating valve not shown in the figure to make The inside of the carbonization tank barrel 30 is filled with carbon dioxide gas at a predetermined pressure. The solenoid valve 32a in the carbon dioxide supply path 32 is provided with a check valve 32b that prevents carbon dioxide from flowing back to the carbon dioxide high pressure container 31 side. Furthermore, a branch pipe 33 into which a safety valve 33a is inserted is connected to the carbonization tank barrel 30 side of the on-off valve 32a in the carbon dioxide supply path 32. When the internal pressure of the carbonization tank barrel 30 rises above a predetermined level, the branch pipe 33 will Carbon dioxide gas is discharged from the carbonization tank 30, thereby reducing the internal pressure to ensure safety.

The carbonization tank barrel 30 is connected to the water supply path 24 from the cold water tank barrel 20, and the carbonated gas supplied from the carbonated gas supply path is added to the water 50 supplied from the water supply path to generate carbonated water 50, and the carbonated water is stored. In more detail, the water 50 supplied from the water supply path 24 is sprayed into the carbonization tank barrel 30 in a mist form through the spray nozzle 34. The water 50 sprayed from the spray nozzle 34 absorbs the carbonic acid gas in the carbonization tank 30 to produce carbonated water 60. In addition, the carbonization tank barrel 30 has a carbonated water delivery path 26 that sends carbonated water 60 as beverage water from the carbonization tank barrel 30, and the carbonated water 60 can be supplied from the carbonated water delivery path 26 by opening the solenoid valve 26a. Since the internal pressure of the carbonization tank barrel 30 increases, if the solenoid valve 26a provided in the carbonated water delivery path 26 is opened, the carbonated water 60 can be supplied from the carbonization tank barrel 30 through the carbonated water delivery path 26 due to the pressure difference. In addition, the end of the carbonated water delivery path 26 on the carbonization tank barrel 30 side is near the bottom of the carbonization tank barrel 30, so that the carbonated water 60 in the tank barrel can be sent up to the upper limit. In addition, the carbonization tank 30 has a water level sensor 35 that measures the water level of the carbonated water 60. When the water level sensor 35 detects a drop in the water level, the high-pressure pump 24b operates, and the water 50 flows into the carbonization tank 30. The carbonated water 60 is sprayed and regenerated (In Figure 1, it is shown that the carbonated water 60 is taken out by the opening of the solenoid valve 26a, the water level sensor 35 detects the drop in the water level, and the high-pressure pump 24b operates and restarts The state of generating carbonated water 60).

Furthermore, the carbonization tank barrel 30 is a cooler that cools the carbonated water 60 in the carbonization tank barrel 30. The outer surface of the carbonization tank barrel 30 is arranged in a spiral shape and has a cooling system that circulates the refrigerant inside by opening the solenoid valve 36a. But the coil 36. In addition, a check valve 36b is provided in a part of the flow path through which the used refrigerant flows to prevent the used refrigerant from flowing backward. In addition, the carbonization tank barrel 30 is equipped with a heater (corresponding to a heater for the carbonization tank barrel) 37 for heating the carbonated water 60 in the carbonization tank barrel 30. In addition, when the carbonated water 60 is heated by the heater 37, a considerable amount of carbonic acid is removed from the carbonated water 60. Therefore, by providing the second branch pipe 38 in the carbon dioxide supply path 32 and opening the solenoid valve 38a, carbonic acid generated when the carbonated water 60 is heated is released from the second branch pipe 38 to the outside.

The warm water tank 40 is a person who stores warm water 70 as a beverage water, and stores the warm water 70 for sterilizing the warm water in the cold water tank 20. In addition, the warm water tank barrel 40 is provided with a heater (equivalent to a heater for the warm water tank barrel) 41 for heating the water in the warm water tank barrel 40, and a heater for supplying the water 50 in the cold water tank barrel 20 to the warm water tank barrel 40 The second water supply path 42 supplies the hot water 70 in the hot water tank tub 40 to the hot water supply path 43 of the cold water tank tub 20. In addition, the hot water supply path 43 includes an electromagnetic valve 43a and a hot water circulation pump 43b. In the warm water tank 40, in the sterilization treatment of the cold water tank 20 described later, the water 50 in the cold water tank 20 is sent out to the warm water tank 40 through the second water supply path 42, and the warm water in the warm water tank 40 The water 70 is sent out to the cold water tank 20 through the warm water supply path 43 only when the water 50 is contained. And, in parallel with this, the water (water 50 and warm water 70) in the warm water tank tub 40 (water 50 and warm water 70) is heated by the heater 41 including the water 50 contained in the cold water tank tub 20. That is, while the water (water 50 and warm water 70) is heated by the heater 41, the water 50 in the cold water tank 20 can be circulated through the second water supply path 42 and the warm water tank 40 and the warm water supply path 43. . By continuing to substantively In the above, the water 50 in the cold water tank 20 is heated by the heater 41, and the cold water tank 20 can be filled with warm water 70. In this way, the warm water tank tub 40, the heater 41, the second water supply path 42, and the warm water supply path 43 function as a heating device for the cold water tank tub that heats the water 50 in the cold water tank tub 20. By heating the cold water tank barrel 20, the cold water tank barrel 20 can be sterilized. Moreover, in this embodiment, since the warm water 70 in the warm water tank 40 can be heated by the water 50 in the cold water tank 20, the water in the cold water tank 20 can be heated efficiently. In addition, the warm water tank 40 is provided with a warm water delivery path 44 for delivering warm water 70 as beverage water from the warm water tank 40. By opening the solenoid valve 44a provided in the warm water delivery path 44, the hot water tank is accessible from the hot water tank. Warm water 70 is provided in the bucket 40.

Furthermore, in the beverage supply device of this embodiment, a branch pipe 27 that connects the water supply path 24 and the carbonated water delivery path 26 is provided. In addition, a solenoid valve 24 a is provided on the upstream side of the branch pipe 27 of the water supply path 24. Thus, the carbonated water delivery path 26, the branch pipe 27, and the water supply path 24 function as a circulation path that circulates the carbonated water 60 in the carbonization tank 30. With the solenoid valve 24a closed, the high-pressure pump Operation 24b circulates the carbonated water 60 in the carbonization tank 30 through the carbonated water delivery path 26, the branch pipeline 27, and the water supply path 24.

In addition, in the beverage supply device of this embodiment, the pipe heater 25 is provided in the water supply path 24. Specifically, they are provided on the upstream side and the downstream side of the check valve 24c one by one. The water in the water supply path 24 is heated by the operation of the heater 25 for pipes, so that the water supply path 24 can be heat sterilized.

In addition, the beverage supply device has a control unit not shown, and switches and timers for various operations not shown. The operation of the switches corresponding to the various parts of the beverage supply device and the timing device are described later by the control unit. Running. In addition, the detection signals of the temperature sensor, pressure sensor, and water level sensor 35 described above are sent to the control unit, and the control unit executes the operation of each unit corresponding to the detection result.

Next, the operation of this beverage supply device will be described with reference to the drawings. Also, in Figures 2 to 6, the solenoid valve in the open state is colored. First, the preparation operation before use will be explained.

[Ready to run]

For example, by pressing the main switch (not shown) of the beverage dispenser, the preparatory operation is started. First, in the preparatory operation, the water 50 is supplied from the water supply source 10 to the cold water tank 20. When the cold water tank 20 is filled with water 50, the cooling coil 21 starts cooling, and the water 50 in the cold water tank 20 is cooled to a set temperature (5-10°C, etc.). In addition, in parallel with the supply and cooling of the water 50, the solenoid valve 32a of the carbon dioxide supply path 32 is opened, and the supply of carbon dioxide to the carbonization tank barrel 30 is started until the internal pressure of the carbonization tank barrel 30 reaches a predetermined value. Up to the above, it is supplied to the carbonization tank barrel 30. The lower the temperature of the water and the higher the pressure of carbon dioxide, the carbon dioxide absorption of the water increases, so the water 50 is set to be cooled until the temperature, and the internal pressure of the carbonization tank 30 reaches a predetermined value. When ascending, the high-pressure pump 24 b is operated to spray the cooled water 50 (water) into the carbonization tank 30. Water 50 is supplied from high pressure to filled with carbon dioxide gas In addition to the carbonization tank 30 of the body, the mist is further formed to increase the contact area between the water 50 and the carbon dioxide gas. As a result, the carbonated water 60 is efficiently generated. In addition, carbonated water 60 is produced up to a predetermined water level. Furthermore, the solenoid valve 43a is opened, and by starting the warm water circulation pump 43b, the water 50 in the cold water tank 20 is supplied to the warm water tank 40 through the second water supply path 42, and the warm water tank 40 is filled with water 50 If this is the case, the heater 41 is heated thereafter. The temperature is detected by a temperature sensor (not shown), and if the temperature rises to a predetermined temperature (for example, 80°C, etc.), the heating of the heater is stopped and the preparatory operation is completed.

[Normal operation]

After the preparatory operation is finished, it enters the normal operation state. For example, by pressing the switch for water supply, water 50 can be supplied from the water outlet 22, and by pressing the switch for carbonated water supply, the carbonated water outlet 26 can be supplied. The carbonated water 60 is provided, and the warm water 70 can be provided from the warm water delivery path 44 by pressing the switch for the warm water supply. In addition, in the normal operating state, the water 50 in the cold water tank 20, the carbonated water 60 in the carbonization tank 30, and the warm water 70 in the warm water tank 40 are maintained within a predetermined temperature range. Not shown. The temperature detected by the temperature sensor of the cooling coils 21, 36 is cooled and the heater 41 is heated at any time. In addition, in order to prevent the carbonic acid from the carbonated water 60 from being released, the internal pressure in the carbonization tank barrel 30 is maintained within a predetermined pressure range, and carbon dioxide gas is supplied to the carbonization tank barrel 30 with a pressure regulating valve not shown.

And for example, when necessary when the specified switch is operated, etc., The operation of adding carbonic acid to the carbonated water 60 in the carbonization tank 30 is performed at a high temperature. Specifically, in a state where carbon dioxide gas is supplied from the carbon dioxide gas supply path 32 to the carbonization tank barrel 30, and the solenoid valve 24a is closed, the high-pressure pump 24b is operated. Thus, the carbonated water 60 in the carbonization tank barrel 30 is circulated through the carbonated water delivery path 26, the branch pipe 27, and the water supply path 24, and the carbonated water 60 is added with carbonate gas again. In this way, carbonic acid can be efficiently contained in the carbonated water 60.

〔Sterilization operation〕

The control unit periodically performs the sterilization operation at intervals determined by the timer in advance. Specifically, the control unit is switchable: using the warm water tank 40 as a heating device for the cold water tank, the heater 41, the second water supply path 42, the warm water supply path 43, and the heater 25 for the pipeline. The sterilization operation on the barrel side of the cold water tank for heat sterilization and the sterilization operation on the barrel side of the carbonization tank for heat sterilization using the heater 37 are performed by the barrel side sterilization operation of the cold water tank and the barrel side sterilization operation of the carbonization tank. In addition, the control unit executes the sterilization operation on the barrel side of the cold water tank at a higher frequency than the sterilization operation on the barrel side of the carbonization tank. Since carbonated water 60 generally has an effect of inhibiting the propagation of bacteria, the frequency of sterilization on the side of the carbonization tank 30 can be reduced compared to the side of the cold water tank 20. In addition, a switch for each sterilization operation may be provided, and each sterilization operation may be performed by operation of the switch. First, the sterilization operation on the barrel side of the cold water tank will be explained using Figures 2 to 4.

〔Sterilization operation on the side of the cold water tank〕

In the cold water tank side sterilization operation, first, as shown in Figure 2, the solenoid valve 43a of the warm water supply path 43 is opened. By starting the warm water circulation pump 43b, the warm water 70 flows from the warm water tank 40 to the cold water tank. The tub 20 is sent out, and the water 50 is sent out from the cold water tank 20 to the warm water tank 40. In addition, the heater 41 also operates at the same time, and at the same time, the water 50 contained in the cold water tank 20 is heated by the heater 41 to heat the water in the warm water tank 40. As a result, the water (water 50 and warm water 70) between the cold water tank 20 and the warm water tank 40 is circulated while being heated by the heater 41, and with this, the water 50 in the cold water tank 20 is essentially borrowed Heated by the heater 41, the temperature of the water in the cold water tank 20 rises. In addition, the heater 25 for pipes is operated to heat the water 50 in the water supply path 24. Also, at this time, as explained in the normal operation, the carbonization tank barrel 30 is maintained at a high internal pressure to prevent the carbonated water 60 from escaping, so the water 50 heated from the water supply path 24 will not flow toward The inside of the carbonization tank barrel 30 flows. By performing this operation to some extent, as shown in Fig. 3, the water temperature in the cold water tank 20 and the water supply path 24 is sufficiently increased (for example, 80°C). And, by maintaining this state for a certain period of time, heat sterilization of the cold water tank 20 and the water supply path 24 is performed. After the sterilization, as shown in FIG. 4, the heater 41 and the pipe heater 25 are stopped, and the refrigerant is circulated in the cooling coil 21 to cool the warm water 70 in the cold water tank 20. In addition, the water supply path 24 is naturally cooled. This completes the sterilization operation on the side of the cold water tank. In this way, in the beverage supply device of the present embodiment, the water supply path 24 that supplies the water 50 to the carbonization tank 30 can also be sterilized.

[Sterilization operation on the barrel side of the carbonization tank]

In the carbonization tank barrel side sterilization operation, first, the solenoid valve 32a of the carbon dioxide supply path 32 is closed to block the supply of carbon dioxide, and then the heater 37 is operated to heat the carbonated water 60. In addition, at this time, since a considerable amount of carbonic acid is extracted from the carbonated water 60, the solenoid valve 38a is opened, and the generated carbonic acid gas is discharged from the second branch pipe 38 to the outside. When the carbonated water 60 is heated to a certain degree, the carbonated water 60 in the carbonization tank 30 is heated by the heater 37 and the solenoid valve 24a is closed, and the high-pressure pump 24b is operated. Thereby, the heated carbonated water 60 (warm water 70) in the carbonization tank barrel 30 is circulated through the carbonated water delivery path 26, the branch pipe 27, and the water supply path 24. By continuously heating and sterilizing the carbonization tank barrel 30, the carbonated water delivery path 26, the branch pipe 27, and the water supply path 24 for this predetermined time.

After the sterilization, the heater 37 and the high-pressure pump 24b are stopped, and the cooling coil 36 cools the carbonated water 60 (warm water 70) in the carbonization tank barrel 20 by circulating a refrigerant in the cooling coil 36.
