BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubbler for carbon dioxide drinks and a server equipped with the bubbler, and more particularly, supplies draft beer from a draft beer barrel to a mug via an instant cooling beer server. The present invention relates to a draft beer service device.

[0002]

2. Description of the Related Art FIG. 4 is a block diagram showing a draft beer server of the instant cooling type.

A carbon dioxide gas is supplied from a carbon dioxide gas cylinder 81 to a fitting 84 of a draft beer barrel 80 via a pressure regulating valve 82 and a gas hose 83. Draft beer in the draft beer barrel 80 is pressed by the carbon dioxide gas supplied from the fitting 84, and is supplied to the beer supply hose 86 via the down tube 87 and the fitting 85. The draft beer supplied to the beer supply hose 86 is
When passing through the cooling coil 91 of the server main body 96 of the draft beer server 90 of the instant cooling type, it is cooled. The cooled draft beer is poured into a glass 93 or the like when the discharge valve 92 is opened. Further, the cooling coil 91 includes a cooling unit 95.
Is cooled by the cooling water in the cooling water tank 94. In addition, reference numeral 88 denotes a bubble cut-off device described later provided with a gas release valve 89.

[0004] If the beer in the draft beer barrel 80 is empty and empty, and the pouring is continued in a state filled with carbon dioxide, carbon dioxide is inevitably mixed into the beer supply hose 86 and the cooling coil 91. Empty draft beer barrel 80 in this state
Is newly replaced and the dispensing operation is performed again. At first, since the carbon dioxide gas and the beer are dispensed in a mixed state, stable dispensing cannot be performed. In extreme cases, 2-3 mugs of beer are wasted. In order to solve this, a bubble opener may be used in some cases.

[0005] Here, the bubble removing device will be described.

As shown in FIG. 4 and FIG.
Reference numeral 8 includes a cylindrical body 97, and a top plate 99 and a bottom plate 98 fixed to the upper and lower ends of the cylindrical body 97, respectively. Top plate 9
9 is provided with a gas vent 101, and a bottom plate 98 is provided with a beer inlet 103 and a beer outlet 104. The beer inlet 103 is connected to an outlet of a beer supply hose 86, and the beer outlet 104 is connected to an inlet of a cooling coil 91. Further, the gas vent port 101 is provided with a gas vent valve 89 via a conduit.

[0007] The liquid level of the beer in the defoamer 88 is maintained at an appropriate constant position. When the amount of beer in the draft beer barrel 80 decreases and carbon dioxide gas is mixed into the beer to be poured, the beer is immediately poured. The outlet valve 92 is closed to stop the pouring operation, and the draft beer barrel 80 is replaced (the fitting 85 is provided with a check valve, and no backflow of beer occurs). Thereafter, the gas vent valve 89 is opened to guide the carbon dioxide gas in the beer supply hose 86 to the bubbler 88. However, the carbon dioxide gas passes through the beer 102, and the beer 102 is in a state of being clogged, and it takes a long time to settle down. A standing time is required. Generally, it is about 30 seconds, and about 60 seconds when it is long.

[0008] In addition, beer supply hose 8 during normal pouring.
When the carbon dioxide gas is separated from the beer due to high temperature or low pressure, for example, inside 6, the gas enters the defoaming device 88 and the beer 86 is trapped, so that the beer is smooth. Can not be dispensed.

[0009]

In the above prior art, since the liquid inlet and the liquid outlet are not partitioned, the liquid near the liquid outlet in the bubble opening device diffuses violently, so that when the beverage container is exchanged, the liquid is not easily exchanged. It requires a long waiting time and the service is degraded, even in a situation where it is necessary to urgently pour out. Also, if carbon dioxide gas is separated in a beer hose or the like even during normal pouring, beer is spilled near the liquid outlet in the bubble opening device, making it impossible to pour beer smoothly.

[0010] The present invention has been made in view of the above-mentioned problems of the prior art, and is capable of quickly discharging a carbon dioxide gas beverage after exchanging a beverage container and a beverage container capable of quickly removing bubbles, It is an object of the present invention to provide a server that can continue pouring even when carbon dioxide gas separation occurs.

And a top plate formed.

In addition, the server of the present invention supplies carbon dioxide gas into a beverage container containing a carbon dioxide beverage,
At the gas pressure, the carbon dioxide beverage is transferred from the beverage container to the server body and poured out. In the server for carbon dioxide beverage, the bubble opening device of the present invention has a liquid inlet and a liquid outlet, the beverage container and the liquid container. The beverage container is interposed between the beverage container and the server main body so as to communicate with the server main body.

[0013]

In the present invention according to the first aspect of the present invention, if carbon dioxide or a mixture of carbon dioxide is supplied from the liquid inlet into the inner cylinder of the bubble removing device, the carbon dioxide is raised upward. It moves and is separated from the liquid, and is discharged from the gas vent to the outside of the bubble removing device. On the other hand, the liquid overflows from the inner cylinder, is contained in the outer cylinder outside the inner cylinder, and exits from the liquid outlet. As described above, since the liquid inlet and the liquid outlet are separated by the inner cylinder, the liquid is leaked in the inner cylinder of the bubble removing device, and the liquid is not leaked near the liquid outlet, and the liquid from which the bubbles are separated. Flows out of the liquid outlet, and the foam is quickly removed.
