Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of connecting a soft drink such as beer or carbonated water packed in a container such as a tank provided with a cooling means with a liquid guide tube such as a hose connecting the container to the container. In a soft drink dispenser that guides to a draft cock that is installed on an appropriate machine such as a counter and pours a predetermined amount from the draft cock into a receiver such as a mug / cop, etc. The present invention relates to a cooling device in a soft drink dispenser for keeping the temperature of soft drink to be taken out at a desired cooling temperature.

[0002]

2. Description of the Related Art The cooling means in the above-mentioned soft drink dispenser is a dispenser for drawing out and dispensing soft drinks such as carbonated water. Specifically, as shown in FIG. 1, soft drinks are packed. Container T such as tank
The dispensing head 1 is attached to the mouth, and the suction outlet 10 of the dispensing head 1 is connected to a cooling tank provided in a water tank 20 filled with cooling water in the cooling machine 2 through an outlet pipe 11 such as a hose. 21 is connected to the inlet side, and the outlet side of the cooling snake tube 21 is connected to the upstream end of a liquid guide tube a such as a hose, and the downstream side of the liquid guide tube a is connected to an appropriate machine such as a counter. A cylinder 5 in which a compressed gas such as carbon dioxide gas or nitrogen gas is filled in a gas connection port of the dispense head 1 connected to a draft cock 4 installed on the table 3 and mounted on the mouth of the container T. The discharge port is connected to a gas hose 51 connected via a regulator 50. When the draft cock 4 is operated to open the discharge port 40, the pressure of the compressed gas in the cylinder 5 is reduced. The beverage extruded from the container T with Through the extraction pipe 11 is sent to the cooling coiled 21 chiller 2, where it is cooled to a predetermined cooling temperature,
It is guided to the draft cock 4 via the liquid guide pipe a, and is taken out from the discharge port 40 thereof.

[0003]

The above-described cooling means for a soft drink uses the cooling device 2 when the take-out of the drink from the draft cock 4 is performed almost continuously.
As a result, the soft drink kept at the cooling temperature set is taken out, but when this taking out is carried out after a certain time, a soft soft drink higher than the set cooling temperature is poured from the discharge port 40 of the draft cock 4. There is a problem that will be issued.

[0004] This is a container T filled with soft drinks.
The cylinder 5 and the cooler 2 are installed collectively in the back of a store kitchen or the like, and only the draft cock 4 is installed on a counter or the like in the store. A hose is connected between the draft cock 4 and the cooler 2. Alternatively, since the connection is often made with the liquid guide pipe a, the liquid guide pipe a from the cooler 2 to the draft cock 4 tends to be long, and when there is an interval for taking out the beverage from the draft cock 4 This is because the soft drink in the liquid guide pipe a between the cooling snake pipe 21 of the cooler 2 and the draft cock 4 is heated by the outside air temperature.

[0005] The problem is that the cooling means may be mounted on the liquid guide pipe a connecting the cooling snake pipe 21 of the cooler 2 and the draft cock 4. Since the place where the draft cock 4 is installed is different depending on the shop where the soft drink dispenser is installed, the length and the state of the pipe of the liquid guide pipe a are changed.
There is a problem that it cannot be manufactured in a factory in advance as a fixed shape, and the cooling means of the liquid guide tube a must be made to match the cooling temperature at which the soft drink is cooled by the cooling snake tube 21 of the cooler 2. Having to do that presents a difficult problem to control.

The present invention has been made in order to solve the above-mentioned problem occurring in the cooling means in the conventional soft drink dispenser. The present invention is directed to pumping the soft drink from the container T and cooling the cooling tube 21 of the cooler 2. While the soft drink cooled to the predetermined temperature is present in the liquid guide pipe a leading from the cooling snake pipe 21 to the draft cock 4, the soft drink is maintained at the predetermined temperature cooled by the cooling snake pipe 21 of the cooler 2. It is an object to provide a new means for feeding the draft cock 4.

[0007]

Means for Solving the Problems In the present invention, as a means for achieving the above-mentioned object, a beverage packed in a container T such as a tank is pumped out by gas pressure to provide a separate cooling machine 2. In a cooling device for cooling a soft drink, cooling is performed by passing through a cooling snake tube 21 stored in a water tank 20 in the machine and guided to a receiving port 41 of a draft cock 4 installed in a machine 3 such as a counter in a store by a liquid guide tube a. A watertight cylindrical chamber w is formed on the outer periphery of the liquid guide pipe a that guides the beverage from the downstream side of the flexible pipe 21 to the receiving port 41 of the draft cock 4, and the cooling pipe 21 in the water tank 20 for cooling the flexible flexible pipe 21 is formed in the chamber w. A cooling device in a soft drink dispenser characterized by circulating a cooling liquid by a pump device P is provided.

A liquid guide pipe a that connects and communicates between the cooling snake pipe 21 and the draft cock 4 so as to circulate and flow between the chamber w that is formed.
Is cooled under the same temperature condition as the cooling snake tube 21 with the refrigerant liquid in the water tank 20 that cools the cooling snake tube 21 for cooling the beverage taken out from the draft cock 4.

As the pipe b forming a chamber w for cooling the liquid guide pipe a from its outer periphery by circulating the refrigerant liquid in the water tank 20, an appropriate pipe such as a steel pipe or a vinyl chloride pipe is used. A flexible vinyl tube that bends freely may be used. And the pipe of the pipe b is the container T
The cylinder 5 and the cooler 2 are installed at a predetermined place such as a corner of a kitchen, and then the draft cock 4 is installed at a place suitable for selling beverages, and between the draft cock 4 and the cooling snake tube 21 of the cooler 2. When a liquid guide pipe a is connected to a pipe, a pipe b is inserted into the outer circumference of the liquid guide pipe a, and the pipe b is piped in a predetermined form. A sealing member 80 formed of a metal material or a synthetic resin material in a mouth shape or a plug shape is fitted to both ends of the pipe b to seal the openings at both ends of the pipe b in a watertight manner. The lumen is formed in a chamber w that is kept watertight.

The seal member 80 is provided with a fitting hole for inserting the liquid guide pipe a and a fitting hole for inserting the communication pipes 73 and 74 so as to pass through in the axial direction. With the liquid guide pipe a and the communication pipes 73 and 74 fitted in the fitting holes in a watertight manner, the pipes b fitted on the outer periphery of the liquid guide pipe a are fitted watertight in the openings at both ends. At this time, when a flexible vinyl tube is used for the pipe b, a fastener 81 such as a hose band is further fastened from the outer peripheral side of the pipe b to the body peripheral surface of the cap-shaped sealing member 80. Into the openings at both ends of the pipe b,
