Description

The present invention relates to a beverage supply device, such as a beverage dispenser and cup type automatic vending machine for supplying a beverage diluted by mixing the diluent with the liquid source.

  Conventionally, a beverage dispenser generally has a structure in which a beverage in which a liquid raw material (hereinafter referred to as “syrup” as appropriate) and a diluent (diluted water or carbonated water) are mixed in a mixing nozzle flows down to a cup (beverage container). It is used. In the case of a structure in which the syrup and the diluting liquid are mixed in the mixing nozzle in this way, the diluted syrup adheres to the inner wall surface of the mixing nozzle and remains, so that there is a possibility that various bacteria may easily propagate. Nozzle cleaning was essential for hygiene management.

  On the other hand, since it is difficult to perform daily nozzle cleaning in a cup-type vending machine, the nozzle that discharges the syrup and the nozzle that discharges the diluent are separated and made to collide with the inner wall surface of the cup. To mix. In the case of this mixing method, the undiluted syrup that remains in the syrup nozzle outlet can maintain a strong acid concentration at which no germs grow.

As described above, since the syrup nozzle and the diluting liquid nozzle are provided separately from each other in the nozzle of the cup type vending machine, there is no possibility that various germs propagate.
However, the cups used in beverage dispensers are different in size and shape, and the position where the cup is placed is not constant, and the positional relationship between the cup inner wall surface and the nozzle is not fixed, so the syrup and dilution on the inner wall surface of the cup It was not possible to adopt a method of mixing by colliding with the liquid.

  In order to solve such inconvenience, for example, Patent Document 1 discloses a beverage in which a syrup flow is discharged downward into a cup, and a dilution water flow discharged from a dilution water nozzle is joined to the syrup flow and mixed in the air. A beverage supply device for supplying a cup to a cup is disclosed.

  In addition, for example, the beverage supply device disclosed in Patent Document 2 filed by the present applicant includes a plurality of syrup nozzles that distribute and discharge syrup and one dilution liquid nozzle that discharges dilution liquid, The syrup distributed and discharged to the syrup nozzle collides with the diluent discharged from the diluent nozzle in the air, and the mixed beverage is allowed to flow down into the cup.

JP 2000-187773 A JP 2007-45496 A

However, in the beverage supply device of Patent Document 1, since the nozzle tip discharge port is circular, there is a problem that the contact area between the syrup and the diluted water is small and the mixture is not sufficiently mixed in the air.
In addition, since the syrup discharged from the nozzle and the dilution water flow down directly into the cup, the syrup and the dilution water do not mix well, so the syrup with high specific gravity sinks to the bottom of the cup, The syrup concentration is high (for example, sugar content 14), the upper beverage has a low syrup concentration (for example, sugar content 6), and the syrup concentration is uneven (for example, sugar content difference 8).

  Further, the beverage supply device of Patent Document 2 includes a plurality of syrup nozzles that distribute and discharge syrup, and the syrup distributed and discharged to the plurality of syrup nozzles collides with the dilution liquid discharged from the dilution liquid nozzle in the air. Due to the mixing method, the structure is complicated, and there is a problem that it is difficult to arrange the syrup nozzle in order to construct an apparatus capable of supplying various kinds of beverages.

The present invention has been made in order to solve the above-described problems, hygienically manages a nozzle for supplying a uniform syrup concentration of a beverage, and a wide variety of beverages in a limited space. and to provide a beverage supply device capable of supplying.
