2. Description of the Related Art Conventionally, drinking water mixed with a vending machine for canned juice and a concentrated undiluted solution (hereinafter referred to as syrup) is poured together with a diluting solution into a container for providing juice and coffee. There is a beverage supply device that provides the following. Therefore, a conventional example of such a beverage supply device will be described with reference to the drawings. FIG. 4 is an external front view showing a conventional beverage supply device, and FIG. 5 is a conceptual diagram showing the beverage supply device. The conventional beverage supply device 51 is provided with nozzles 52 to 55 for each drinking water as shown in FIG. 4 if it supplies four types of drinking water, for example. That is, as shown in FIG. 5, syrup tanks 56 to 59 of different types of syrups A to D.
Are connected to corresponding ones of the valves 60 to 63, and
A diluent tank 64 for a diluent to be mixed with the syrup is connected to the valves 60 to 63.

In the conventional beverage supply device 51 having such a configuration, when a desired drinking water switch is turned on by a purchaser, a corresponding one of the valves 60 to 63 is opened and closed. And the corresponding syrup tanks 56-5
A predetermined amount of syrup and a diluent supplied from the diluent 9 and the diluent tank 64 are discharged from any of the nozzles 52 to 55 and mixed in the container to provide drinking water.

However, such a beverage supply device 51
Had the following problems. That is, did note out of the different nozzles is provided a separate valve for each syrup becomes difficult to secure the installation space device themselves may have become larger. This is particularly acute now that land prices have risen due to soaring land prices. Further, for supplying dilution liquid to each valve 60-63 are connected to branched supply pipe from the diluent tank 64
Jar in the pipe becomes too complicated for you, workability at the time of manufacture and maintenance of the apparatus has become very bad.

[0005] To solve such a problem, a beverage supply device as shown in FIGS. 6 and 7 has been devised. FIG. 6 is an external view of the beverage supply device, and FIG.
It is a figure showing the concept of the supply device for drinks. The beverage supply device 71 includes one nozzle 72 as shown in FIG. As shown in FIG. 8, the syrup tanks 56 to 59 and the diluent tank 64 are connected to a multi-valve 73 (to be described in detail later), and the multi-valve 73 is connected to the nozzle 72.

[0006]

However, in such a beverage supply device 51, the installation space can be reduced, and the structure of the piping can be simplified.
The following new problems have arisen. That is, although the installation space can be reduced by using one nozzle 72, since all the syrup is poured out through the multi-valve 73, when making drinking water, the syrup that was previously discharged is mixed with the multi-valve. It will remain in 73 and will be flushed and poured out. At this time, the amount of the remaining syrup is a very small amount because it is only the syrup adhering in the multi-valve 73. However, syrups also have various flavors and color strengths, so if a thin one is selected after a strong one, or a colorless and transparent one after a colored one, the taste and appearance Can cause discomfort. There is no problem if the beverage supply device 71 is used frequently, but if the beverage supply device 71 is not used for a long time, it will be left inside the multi-valve 73. In such a case, especially in summer when the temperature rises, breeding of mold and the like may occur even for a relatively short time.

Accordingly, an object of the present invention is to provide a beverage supply device which prevents mixing of different syrups and prevents the occurrence of mold and the like by the syrup.

Further, the valve 12 is connected to a carbonated water supply path 36 for supplying carbonated water, and the valve 13 is connected to a cold water supply path 37 for supplying cold water. Further, in the present embodiment, the carbonated water supply passage 36 connected to the valve 12 is also connected to the valve 21 communicating with the stock solution supply hole 1a via the throttle valve 38.
The carbonated water supply path 36 branches on the way and communicates with the return path 40 via the evaporator 39. A controller 22 is connected to the multi-valve 6 to control the opening and closing of each valve.

The beverage supply device 20 according to the present embodiment having such a configuration operates as follows. When the purchaser turns on the switch of the drinking water desired by the purchaser, the drinking supply device 20 opens and closes the syrup valve corresponding to the drinking water by driving means (not shown), as in the above-described conventional example.
A predetermined amount of the syrup and the diluent are poured into the container 30 on the mounting table 25. Specifically, assuming that the syrup carbonated drinking water supplied to the valve 8 is selected, the valve 8c opens for a predetermined time. Then, the inside of the syrup supply path 32 becomes 3.5.
The syrup that has been supplied under a pressure of kg flows from the valve hole 8a through the valve hole 8b into the undiluted solution supply hole 1a, and is further discharged through the pouring hole 2a into the container 30 from the pouring port 4. It is. Then, as the syrup is poured, the valve body 12c opens for a predetermined time. Then, the carbonated water supplied under the pressure of 6 kg in the carbonated water supply passage 36 flows into the communication hole 1b through the valve hole 12b, and further flows through the communication hole 2b to the container 30 from the outlet 4. It is poured in.

The beverage supply device 2 of the present embodiment
0, the carbonated water further supplied to the valve 21 through the carbonated water supply passage 36 is supplied to the undiluted solution supply hole 1 after the syrup flows.
a by the opening and closing of the valve 21 at a predetermined timing. The trace amount of carbonated water flows out together with the syrup remaining in the stock solution supply hole 1a and the pouring hole 2a, and is also poured into the container 30. In this way, the syrup and the carbonated water are poured into the container 30, and the desired carbonated water is provided.

Now, a description will be given with reference to a time chart of the syrup and the diluent thus discharged. FIG.
FIG. 2 is a diagram showing a time chart of the beverage supply device 20 of the present embodiment in comparison with a conventional one. FIG. 1A shows a conventional example, and FIG. 1B shows an example of the present embodiment. In the conventional beverage supply device 71, the syrup and the diluent are simultaneously poured out for the same time (5 seconds). On the other hand, in the beverage supply device 20 of the present embodiment, the syrup and the diluent are simultaneously poured out, but the diluent is discharged for 4.6 seconds, whereas the syrup is discharged only for 4.4 seconds. So that
4.6 seconds after the start of the pouring, the carbonated water was discharged from the valve 21 for 0.4 seconds. At this time, the amount of this embodiment and the conventional example also poured into the container was 200 cc in total, 30 cc of syrup and 17 liter of diluent.
0 cc.

In this embodiment, in particular, 1
Of the 70 cc diluent, 7 to 10 cc of carbonated water flows out of the valve 21 for cleaning. By the way, when the valve 21 is opened, the carbonated water supplied at a pressure of 6 kg increases its flow rate by the throttle valve 38 and flows into the stock solution supply hole 1a vigorously, and the stock solution supply hole 1a and the discharge hole 2a. Then, the syrup remaining in the valve holes 8a, 9a, 10a, and 11a is flushed and discharged from the spout 4. In addition, since the amount of carbonated water for cleaning is very small, there is no effect even if the selected diluent of drinking water is cold water supplied from the cold water supply path 37, and the carbonated water supply path 36 for cleaning is not affected. Supplies carbonated water.

In the beverage supply device 20 of the present embodiment,
As can be seen from the time chart, a time lag of 0.2 seconds occurs between the syrup flowing through the stock solution supply hole 1a and the carbonated water. This is because flowing the carbonated water in a state where the syrup is poured out and the flow in the stock solution supply hole 1a is stopped is more effective in removing the syrup remaining in the stock solution supply hole 1a. The reason for setting the time to 0.4 seconds is that, as described above, an appropriate amount of the diluent for washing is 7 to 10 cc, and if it is less than that, syrup is not sufficiently removed. This is because the syrup of the water itself and the diluent are not well mixed.

The configuration and operation of the embodiment of the beverage supply device 20 have been described above. According to this, the following effects can be obtained. After pouring out the syrup, the undiluted solution supply hole 1a and the pouring hole 2a, in which the remaining syrup remains exposed to the atmosphere, are washed. Therefore, the remaining syrup is removed, and a sanitary beverage in which mold propagation is prevented. It became possible to provide a supply device for use. Since the diluent carbonated water was used as the washing liquid for washing the syrup in the undiluted solution supply hole 1a,
There is no need to separately provide a tank for the cleaning liquid or a pipe for the cleaning liquid, so that the structure can be simplified and the cost can be reduced.

The beverage supply device of the present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the invention. For example, in the above embodiment, a case where four types of syrups are supplied has been described, but there is no problem even if more valves are provided. Further, in the embodiment, the carbonated water was used for cleaning, but this is because carbonated water has a more bactericidal effect than cold water,
For example, if hot water is used as the diluent, hot water may be used for washing.
