Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which a soft drink such as beer or carbonated water packed in a container such as a tank provided with cooling means is placed in the container. A soft drink that leads to a draft cock installed on an appropriate machine such as a counter through a liquid guide tube such as a hose to be connected, and pours out a predetermined amount from the draft cock to a receiver such as a mug or cup. The present invention relates to a cooling device in a soft drink dispenser for keeping the temperature of soft drink taken out of a draft cock into a cup or the like at a desired cooling temperature. [0002] The cooling means in the above-mentioned soft drink dispenser is a dispenser that draws out and distributes soft drink such as carbonated water. Specifically, as shown in FIG. Containers T such as tanks
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-mentioned means for cooling a soft drink uses the cooling device 2 when the drink is taken out from the draft cock 4 in a substantially continuous state.
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 of 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. According to 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 and cooled separately. A cooling device for a soft drink, which is cooled by passing through a cooling coil 21 stored in a water tank 20 in the machine 2 of the machine 2 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 pipe a. In the above, a pipe b made of a vinyl tube having an inner diameter larger than that of the liquid guide tube a is inserted around the outer periphery of the liquid guide tube a that guides the beverage from the downstream side of the cooling snake tube 21 to the receiving port 41 of the draft cock 4. Are provided with a fitting hole through which the liquid guide pipe a is inserted and a fitting hole through which the communication pipes 73 and 74 are inserted, and a seal member 80 formed in a base shape is fitted to seal watertightly.

And a communication pipe 73 communicating with a discharge port 71 of a pump device P in which a suction port 70 communicates with a cooling water tank 20 through a communication pipe 72 with a cooling water tank 20 for cooling.
Into the fitting hole provided in the sealing member 80 from the side opposite to the draft cock 4 of the chamber w, and penetrate through the chamber w to seal the sealing member 80 on the side adjacent to the draft cock 4. It is made to penetrate and protrude to the outside, and its protruding end is made to make a U-turn outside and inserted again into the chamber w through the fitting hole opened in the seal member 80 and at a position close to the draft cock 4, the chamber w The end of the chamber w on the side away from the draft cock 4 is communicated with the water tank 20 by a communication pipe 74, and the cooling liquid in the water tank 20 for cooling the cooling snake pipe 21 is supplied to the chamber w by the pump device P.
