BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage supply device for providing mixed drinking water by pouring into a container a stock solution for beverage and a diluent for diluting the stock solution, and more particularly, a plurality of stock solutions. The present invention relates to a beverage supply device for producing and providing drinking water by pouring water from one pouring outlet.

[0002]

2. Description of the Related Art Conventionally, for providing juice, coffee, etc., together with an automatic vending machine for canned juice, a concentrated stock solution (hereinafter referred to as syrup) is poured together with a diluting solution into a single drinking water There is a beverage supply device that provides 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. If the conventional beverage supply device 51 supplies, for example, four types of drinking water, as shown in FIG. 4, each of the drinking water is provided with nozzles 52 to 55. That is, as shown in FIG. 5, syrup tanks 56-59 of different types of syrups A-D are shown.
Is connected to the corresponding one of the valves 60-63, and
A diluent tank 64 for the 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 the purchaser turns on the desired drinking water, the corresponding one of the valves 60 to 63 is opened and closed. And corresponding syrup tanks 56-5
9 and a predetermined amount of syrup and diluent supplied from the diluent tank 64 are poured out 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, if an independent valve is provided for each syrup and the syrup is poured out from different nozzles, the size of the device itself becomes large, and it is difficult to secure an installation space. This is especially serious at the present time when the rent for installation has become higher due to the rise in land prices. Further, in supplying the diluting liquid to each of the valves 60 to 63, the supply pipe is branched from the diluting liquid tank 64 to make the connection quantity, and therefore the piping becomes complicated, and the workability at the time of manufacturing and maintenance of the device is extremely high. It became bad.

Then, as a beverage supply device for solving such a problem, a 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 the figure which showed the concept of the supply apparatus for drinks. The beverage supply device 71 includes one nozzle 72 as shown in FIG. Then, as shown in FIG. 8, the syrup tanks 56 to 59 and the diluent tank 64 are connected to a multi-valve 73 (details of which will be described later), and the multi-valve 73 is connected to the nozzle 72. When the purchaser turns on a desired switch, the beverage supply device 71 having such a configuration communicates with the predetermined syrup tanks 56 to 59 and the diluting liquid tank 64 of the multi-valve 73,
Drinking water is dispensed from the nozzle 72.

[0006]

However, such a beverage supply device 51 can reduce the installation space and simplify the pipe structure.
The following new problems have arisen. That is, although the nozzle 72 was made one and the installation space could be made small, since all the syrup is poured out through the multi-valve 73, when the drinking water is made, the syrup poured before is the multi-valve. It remains in 73 and will be poured and poured together. At this time, the amount of the previous syrup remaining is a very small amount because it is only the amount attached to the inside of the multi-valve 73. However, syrup also has various tastes and color strengths, so if you select a dark one after a strong taste, or a colorless and transparent one after a colored one, the taste and appearance will be different. There may be a feeling of strangeness. Further, when the beverage supply device 71 is frequently used, there is no problem, but when the beverage supply device 71 is not used for a long time, it is left in the multi-valve 73. In such a case, especially in summer when the temperature rises, the reproduction of mold and the like can occur even for a relatively short time.

[0007] Therefore, an object of the present invention is to provide a beverage supply device which prevents mixing of different syrups and prevents generation of mold and the like due to the syrups.

By the way, the pouring hole 2a formed in the diffuser 2 is formed coaxially with the undiluted solution supply hole 1a and communicates therewith.

First, the multi-valve 6 is formed with a syrup supply section 6a composed of valves 8, 9, 10, 11 for supplying four types of syrups. All the valves 8, 9, 10, 11 have the same structure, and valve holes 8a, 9a, 10a, 11 formed on the side surface of the body 1
a, valve holes 8b, 9b, 10 communicating with the stock solution supply hole 1a.
b, 11b are formed and their valve holes 8b, 9b, 10b,
Valve bodies 8c, 9c, 10c, 11 for opening and closing 11b
c is fitted in the valve holes 8a, 9a, 10a, 11a.

On the other hand, the beverage supply device 20 of the present embodiment
The feature of the above is that the valve 21 is provided at the upper part of the syrup supply part 6a of the multi-valve 6, that is, at the most upstream part of the stock solution supply hole 1a. This valve 21 also has the same structure as the valve 8 of the syrup supply unit 6a and the like, and a valve hole 21b communicating with the undiluted solution supply hole 1a is formed in the valve hole 21a.
1c is inserted.

Further, below the syrup supply section 6a, there is formed a diluent supply section 6b constituted by valves 12 and 13 for supplying cold water and carbonated water for diluting the poured syrup. At this time, the valve 12 is distinguished for carbonic acid and the valve 13 for cold water. The structure of the valve hole 12 is the same as that of the valve 8 and the like.
a, 13a communicates with the valve holes 12b, 13b, and the valve body 12
c and 13c are inserted and formed. The communication holes 1b and 1c formed in the body 1 and the communication holes 2b and 2c formed in the diffuser 2 are in communication with each other, from the valve holes 12b and 13b to the spout 4.

Here, FIG. 2 is a conceptual diagram of the beverage supply device 20. As shown in the figure, valves 8, 9, 10, 1
1 is connected to syrup supply paths 32, 33, 34 and 35 for supplying different syrups. The valve 12 is connected to a carbonated water supply passage 36 for supplying carbonated water, and the valve 13 is connected to a cold water supply passage 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.
Further, the carbonated water supply path 36 is branched on the way and communicated with the return path 40 via an evaporator 39. A controller 22 is connected to the multi-valve 6 so as to control the opening / closing of each valve.

The beverage supply device 20 of the present embodiment having such a structure operates as follows. Like the conventional example, the beverage supply device 20 turns on and off the syrup valve corresponding to the drinking water by driving means (not shown) when the purchaser turns on the drinking water switch desired by the purchaser.
A predetermined amount of syrup and diluent are poured into the container 30 on the mounting table 25. Specifically, if the carbonated drinking water of the syrup supplied to the valve 8 is selected, the valve body 8c opens for a predetermined time. Then, the inside of the syrup supply path 32 is set to 3.5.
The syrup supplied under the pressure of kg flows from the valve hole 8a through the valve hole 8b into the undiluted solution supply hole 1a, and then through the pouring hole 2a to the pouring port 4 into the container 30. Be done. Then, as the syrup is poured out, the valve body 12c opens for a predetermined time. Then, the carbonated water which has been supplied with a pressure of 6 kg in the carbonated water supply passage 36 flows into the communication hole 1b through the valve hole 12b, and further through the communication hole 2b from the spout 4 to the container 30. It is poured in.

Then, the beverage supply device 2 of the present embodiment
At 0, the carbonated water further supplied to the valve 21 through the carbonated water supply passage 36 is the stock solution supply hole 1 after the syrup flows.
A small amount of a is flown by opening and closing the valve 21 at a predetermined timing. This small amount of carbonated water is poured 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 carbonated water are poured into the container 30 to provide the desired carbonated water.

By the way, a time chart of the syrup and the diluting liquid thus dispensed will be shown and described. FIG.
FIG. 7 is a diagram showing a time chart of the beverage supply device 20 of the present embodiment in comparison with a conventional one. The figure (a) is a conventional one and the figure (b) is that of the present embodiment. In the conventional beverage supply device 71, the syrup and the diluting liquid 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 diluting liquid are simultaneously poured out, but the diluting liquid is poured out for 4.6 seconds, whereas the syrup is poured for only 4.4 seconds. So that
Carbonated water was poured out from the valve 21 for 0.4 seconds after 4.6 seconds from the start of pouring. At this time, the total amount of this embodiment and the conventional example poured into the container is 200 cc, of which syrup is 30 cc and diluent is 17 cc.
0 cc.

In particular, in the present embodiment, 1
Carbonated water flows out from the valve 21 for cleaning 7 to 10 cc of the 70 cc of the diluted solution. 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 vigorously flows into the undiluted solution supply hole 1a, and the undiluted solution supply hole 1a and the spout hole 2a are supplied. Then, the syrup remaining in the valve holes 8a, 9a, 10a, 11a is washed away and poured out from the spout 4. Further, since the carbonated water for cleaning is in a small amount in this way, even if the selected diluting liquid of drinking water is cold water supplied from the cold water supply passage 37, there is no influence, and for cleaning, the carbonated water supply passage 36 is used. Carbonated water is supplied from.

In the beverage supply device 20 of this embodiment,
As can be seen from the time chart, there is a 0.2 second time lag between the syrup flowing through the stock solution supply hole 1a and the carbonated water. This is because it is more effective to remove the syrup remaining in the stock solution supply hole 1a by 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. In addition, what was set to 0.4 seconds, 7 to 10 cc is an appropriate amount as a diluting solution for washing as described above, and if it is less than that, syrup removal is insufficient, while if it is more than that, the beverage This is because the syrup of the water itself and the diluting liquid will not mix well.

The configuration and operation of one embodiment of the beverage supply device 20 have been described above, but according to this, the following effects can be obtained. After pouring out the syrup, the remaining syrup remains in contact with the atmosphere, so that the undiluted solution supply hole 1a and the pouring hole 2a are cleaned, so that the residual syrup is removed and a hygienic beverage that prevents the growth of mold. It has become possible to provide a supply device for use. Since carbonated water, which is a diluting solution, is used as a cleaning liquid for cleaning the syrup in the stock solution supply hole 1a,
It was not necessary to separately provide a tank for the cleaning liquid or a pipe for that purpose, and it was possible to simplify the structure and reduce the cost.

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

[0025]

The present invention provides drinking water in which two or more different stock solutions for drinking water and a diluting solution for diluting the stock solution are mixed by pouring into a container. Multiple stock solution valves that control the inflow of each stock solution into the stock solution outlets that share the same stock solution, and dilution into the dilute solution pouring hole that juxtaposes the dilution solution that is installed in parallel with the stock solution pouring holes. One or two or more diluent valves for controlling the inflow of the liquid are formed, and a cleaning liquid valve for controlling the inflow of the cleaning liquid into the undiluted liquid pouring hole is provided at the most upstream part of the undiluted liquid pouring hole. Therefore, it is possible to provide a beverage supply device that prevents different syrups from mixing with the provided drinking water, and that prevents syrup from causing mold and the like.
